- collisions between the XR data bursts 215 and the measurement gaps 240 may have one or more impacts on the wireless communications system 200.
- the XR data burst 215-b that corresponds to the XR data message 225-a may completely overlay with the measurement gap 240-b. Thus, a relatively large portion of the XR data message 225-a may be canceled resulting in the UE 115-a having to perform one or more retransmissions thus increasing the latency of the XR data traffic within the wireless communications system 200.
- the network entity 105-a may transmit a duration-based or bitmap-based indication to dynamically indicate the UE 115-a to skip one or more measurement gap occasions. For example, if a duration is indicated, the UE 115-a may activate or deactivate the measurement gaps 240 in one or more measurement occasions for the indicated duration. Further, if a bit string is used to indicate the activation or deactivation of the measurement gaps 240, the UE 115-a may use the bit string to indicate a measurement gap 240 that is disconnected. In some examples, to indicate the measurement gap 240 activation or deactivation, the network entity 105-a may transmit a DCI message to notify the information to the UE 115-a.
- the network entity 105-a may transmit the information within a format of the DCI. In some other cases, the network entity 105-a may reinterpret or reuse a format or parameter of the DCI to indicate the activation or deactivation information. Additionally, or alternatively, in the case that a measurement gap 240 duration overlaps with a CDRX-ON state and a XR data burst 215, part of the measurement gap 240 may be indicated as deactivated for a XR traffic transmission while the remaining part of the measurement gap 240 can be used as a measurement gap 240 that is activated.

Abstract
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a control message that indicates a first measurement gap pattern for the UE where the first measurement gap pattern is from a set of one or more measurement gap patterns for the UE. The UE may then receive a message indicating an adaptation to the first measurement gap pattern based on a latency target associated with traffic for the UE. Further, the adaptation may include an adjustment of one or more UE operational parameters associated with the first measurement gap or a switch from the first measurement gap pattern to a second measurement gap pattern. Thus, the UE may operate, in response to the message, in accordance with the adaptation to the first measurement gap pattern during a measurement gap occasion.

These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power) . Examples of such multiple-access systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may be referred to as New Radio (NR) systems. These systems may employ technologies such as code division multiple access (CDMA) , time division multiple access (TDMA) , frequency division multiple access (FDMA) , orthogonal FDMA (OFDMA) , or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM) . A wireless multiple-access communications system may include one or more base stations, each supporting wireless communication for communication devices, which may be known as user equipment (UE) .
The described techniques relate to improved methods, systems, devices, and apparatuses that support measurement gap adaptation.

In some examples, a network entity may configure a user equipment (UE) with one or more measurement gaps to perform inter-frequency or inter-radio access technology (RAT) measurements, beam measurements, or intra-frequency measurements when an active bandwidth part (BWP) of a UE does not include a synchronization signal block (SSB) . During a measurement gap, the measurement gap may take priority and a UE may refrain from transmitting any uplink messages, receiving any downlink messages, or both.
In some cases, a UE may communicate (e.g., transmit or receive) extended reality (XR) data traffic. XR data may include virtual reality (VR) data, augmented reality (AR) data, mixed reality (MR) data, and other types of data which may be associated with high reliability and low latency transmissions. The UE may transmit a set of XR data to the network entity, or receive a set of XR data from the network entity, during a given time interval in a burst fashion such that XR traffic above a threshold amount occurs periodically or inconsistently in time as opposed to consistently throughout a given time interval. In some cases, one or more XR traffic bursts may collide with or overlap one or more measurement gaps (e.g., periods of time during which a UE is scheduled or configured to perform measurements) , thus impacting the latency of the XR data transmissions. Because XR data may have relatively stringent latency targets and such collisions may be unavoidable, collisions between measurement gaps and the XR data may result in a decrease of the reliability and efficiency of XR traffic communications in a wireless communications system.
Further, while the UE and the network entity may adjust the periodicities of one or more measurement gaps and XR data collisions may still occur. For example, the configured periodicity of measurement gaps may be configured to align with a SSB window which may be unaligned with the XR data traffic bursts. Further, such collisions may reduce the reliability and efficiency of a wireless communications system while increasing the latency of the wireless communications system.
The techniques of the present disclosure include signaling to semi-statically or persistently prioritize XR traffic data over measurement gaps, or vice versa. For example, a UE may receive an indication from a network entity that indicates measurement gap pattern for the UE from a set of (e.g., pre-configured) measurement gap patterns. A measurement gap pattern may indicate a periodicity for one or more measurement gap occasions where a UE performs one or more measurements (e.g., inter-frequency measurements, inter-RAT measurements, BWP measurements for the inactive BWPs, or any combination thereof) for a respective serving cell. The periodicity of the measurement gap pattern may further indicate a duration (e.g., a length of time) between each respective measurement gap occasion, thus indicating the frequency of occasions in which the UE performs measurements during a respective measurement gap occasion. Further, a measurement gap occasion where the UE
performs one or more measurements may also be referred to as a measurement gap elsewhere herein. Thus, it should be obvious to one having ordinary skill in the art that a measurement gap may be the same as a measurement gap occasion.
Following, the UE may receive an indication from the network entity to adapt the measurement gap pattern of the UE. For example, the network entity may indicate for the UE to switch from a sparse measurement gap pattern (e.g., a pattern with measurement gap occasions farther apart in time) to a dense measurement gap pattern (e.g., a pattern with measurement gap occasions closer together in time) . In another example, the network entity may indicate to the UE to skip one or more measurement gaps or to refrain from skipping one or more measurement gaps. Such indications may be triggered to indicate the measurement gap adaptation, a duration for the adaptation, or both. Further, the network entity may transmit the measurement gap adaptation indication via a downlink control information (DCI) message where the adaptation indication is indicated via at least one parameter field of the DCI message. Thus, the UE may operate in accordance with the indicated measurement gap adaptation to support a more reliable and efficient wireless communications system.
Aspects of the disclosure are initially described in the context of wireless communications systems. Additional aspects of the disclosure are described with refence to a wireless communications system, a signaling diagram, and a process flow. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to measurement gap adaptation.
FIG. 1 shows an example of a wireless communications system 100 that supports measurement gap adaptation in accordance with one or more aspects of the present disclosure. The wireless communications system 100 may include one or more network entities 105, one or more UEs 115, and a core network 130. In some examples, the wireless communications system 100 may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, a New Radio (NR) network, or a network operating in accordance with other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.
The network entities 105 may be dispersed throughout a geographic area to form the wireless communications system 100 and may include devices in different forms or having different capabilities. In various examples, a network entity 105 may be referred to as a network element, a mobility element, a radio access network (RAN) node, or network equipment, among other nomenclature. In some examples, network entities 105 and UEs 115 may wirelessly communicate via one or more communication links 125 (e.g., a radio frequency (RF) access link) . For example, a network entity 105 may support a coverage area 110 (e.g., a geographic coverage area) over which the UEs 115 and the network entity 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area over which a network entity 105 and a UE 115 may support the communication of signals according to one or more radio access technologies (RATs) .
The UEs 115 may be dispersed throughout a coverage area 110 of the wireless communications system 100, and each UE 115 may be stationary, or mobile, or both at different times. The UEs 115 may be devices in different forms or having different capabilities. Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be capable of supporting communications with various types of devices, such as other UEs 115 or network entities 105, as shown in FIG. 1.
As described herein, a node of the wireless communications system 100, which may be referred to as a network node, or a wireless node, may be a network entity 105 (e.g., any network entity described herein) , a UE 115 (e.g., any UE described herein) , a network controller, an apparatus, a device, a computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, a node may be a UE 115. As another example, a node may be a network entity 105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a UE 115. In another aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a network entity 105. In yet other aspects of this example, the first, second, and third nodes may be different relative to these examples. Similarly, reference to a UE 115, network entity 105, apparatus, device, computing system, or the like may include
disclosure of the UE 115, network entity 105, apparatus, device, computing system, or the like being a node. For example, disclosure that a UE 115 is configured to receive information from a network entity 105 also discloses that a first node is configured to receive information from a second node.
In some examples, network entities 105 may communicate with the core network 130, or with one another, or both. For example, network entities 105 may communicate with the core network 130 via one or more backhaul communication links 120 (e.g., in accordance with an S1, N2, N3, or other interface protocol) . In some examples, network entities 105 may communicate with one another via a backhaul communication link 120 (e.g., in accordance with an X2, Xn, or other interface protocol) either directly (e.g., directly between network entities 105) or indirectly (e.g., via a core network 130) . In some examples, network entities 105 may communicate with one another via a midhaul communication link 162 (e.g., in accordance with a midhaul interface protocol) or a fronthaul communication link 168 (e.g., in accordance with a fronthaul interface protocol) , or any combination thereof. The backhaul communication links 120, midhaul communication links 162, or fronthaul communication links 168 may be or include one or more wired links (e.g., an electrical link, an optical fiber link) , one or more wireless links (e.g., a radio link, a wireless optical link) , among other examples or various combinations thereof. A UE 115 may communicate with the core network 130 via a communication link 155.
One or more of the network entities 105 described herein may include or may be referred to as a base station 140 (e.g., a base transceiver station, a radio base station, an NR base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB) , a next-generation NodeB or a giga-NodeB (either of which may be referred to as a gNB) , a 5G NB, a next-generation eNB (ng-eNB) , a Home NodeB, a Home eNodeB, or other suitable terminology) . In some examples, a network entity 105 (e.g., a base station 140) may be implemented in an aggregated (e.g., monolithic, standalone) base station architecture, which may be configured to utilize a protocol stack that is physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as a base station 140) .
In some examples, a network entity 105 may be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a
disaggregated RAN architecture) , which may be configured to utilize a protocol stack that is physically or logically distributed among two or more network entities 105, such as an integrated access backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance) , or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN) ) . For example, a network entity 105 may include one or more of a central unit (CU) 160, a distributed unit (DU) 165, a radio unit (RU) 170, a RAN Intelligent Controller (RIC) 175 (e.g., a Near-Real Time RIC (Near-RT RIC) , a Non-Real Time RIC (Non-RT RIC) ) , a Service Management and Orchestration (SMO) 180 system, or any combination thereof. An RU 170 may also be referred to as a radio head, a smart radio head, a remote radio head (RRH) , a remote radio unit (RRU) , or a transmission reception point (TRP) . One or more components of the network entities 105 in a disaggregated RAN architecture may be co-located, or one or more components of the network entities 105 may be located in distributed locations (e.g., separate physical locations) . In some examples, one or more network entities 105 of a disaggregated RAN architecture may be implemented as virtual units (e.g., a virtual CU (VCU) , a virtual DU (VDU) , a virtual RU (VRU) ) .
The split of functionality between a CU 160, a DU 165, and an RU 170 is flexible and may support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combinations thereof) are performed at a CU 160, a DU 165, or an RU 170. For example, a functional split of a protocol stack may be employed between a CU 160 and a DU 165 such that the CU 160 may support one or more layers of the protocol stack and the DU 165 may support one or more different layers of the protocol stack. In some examples, the CU 160 may host upper protocol layer (e.g., layer 3 (L3) , layer 2 (L2) ) functionality and signaling (e.g., Radio Resource Control (RRC) , service data adaption protocol (SDAP) , Packet Data Convergence Protocol (PDCP) ) . The CU 160 may be connected to one or more DUs 165 or RUs 170, and the one or more DUs 165 or RUs 170 may host lower protocol layers, such as layer 1 (L1) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU 160. Additionally, or alternatively, a functional split of the protocol stack may be employed between a DU 165 and an RU 170 such that the DU 165 may support one or more layers
of the protocol stack and the RU 170 may support one or more different layers of the protocol stack. The DU 165 may support one or multiple different cells (e.g., via one or more RUs 170) . In some cases, a functional split between a CU 160 and a DU 165, or between a DU 165 and an RU 170 may be within a protocol layer (e.g., some functions for a protocol layer may be performed by one of a CU 160, a DU 165, or an RU 170, while other functions of the protocol layer are performed by a different one of the CU 160, the DU 165, or the RU 170) . A CU 160 may be functionally split further into CU control plane (CU-CP) and CU user plane (CU-UP) functions. A CU 160 may be connected to one or more DUs 165 via a midhaul communication link 162 (e.g., F1, F1-c, F1-u) , and a DU 165 may be connected to one or more RUs 170 via a fronthaul communication link 168 (e.g., open fronthaul (FH) interface) . In some examples, a midhaul communication link 162 or a fronthaul communication link 168 may be implemented in accordance with an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities 105 that are in communication via such communication links.
In wireless communications systems (e.g., wireless communications system 100) , infrastructure and spectral resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, providing an IAB network architecture (e.g., to a core network 130) . In some cases, in an IAB network, one or more network entities 105 (e.g., IAB nodes 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as a donor entity or an IAB donor. One or more DUs 165 or one or more RUs 170 may be partially controlled by one or more CUs 160 associated with a donor network entity 105 (e.g., a donor base station 140) . The one or more donor network entities 105 (e.g., IAB donors) may be in communication with one or more additional network entities 105 (e.g., IAB nodes 104) via supported access and backhaul links (e.g., backhaul communication links 120) . IAB nodes 104 may include an IAB mobile termination (IAB-MT) controlled (e.g., scheduled) by DUs 165 of a coupled IAB donor. An IAB-MT may include an independent set of antennas for relay of communications with UEs 115, or may share the same antennas (e.g., of an RU 170) of an IAB node 104 used for access via the DU 165 of the IAB node 104 (e.g., referred to as virtual IAB-MT (vIAB-MT) ) . In some examples, the IAB nodes 104 may include DUs 165 that support communication links
with additional entities (e.g., IAB nodes 104, UEs 115) within the relay chain or configuration of the access network (e.g., downstream) . In such cases, one or more components of the disaggregated RAN architecture (e.g., one or more IAB nodes 104 or components of IAB nodes 104) may be configured to operate according to the techniques described herein.
For instance, an access network (AN) or RAN may include communications between access nodes (e.g., an IAB donor) , IAB nodes 104, and one or more UEs 115. The IAB donor may facilitate connection between the core network 130 and the AN (e.g., via a wired or wireless connection to the core network 130) . That is, an IAB donor may refer to a RAN node with a wired or wireless connection to core network 130. The IAB donor may include a CU 160 and at least one DU 165 (e.g., and RU 170) , in which case the CU 160 may communicate with the core network 130 via an interface (e.g., a backhaul link) . IAB donor and IAB nodes 104 may communicate via an F1 interface according to a protocol that defines signaling messages (e.g., an F1 AP protocol) . Additionally, or alternatively, the CU 160 may communicate with the core network via an interface, which may be an example of a portion of backhaul link, and may communicate with other CUs 160 (e.g., a CU 160 associated with an alternative IAB donor) via an Xn-C interface, which may be an example of a portion of a backhaul link.
An IAB node 104 may refer to a RAN node that provides IAB functionality (e.g., access for UEs 115, wireless self-backhauling capabilities) . A DU 165 may act as a distributed scheduling node towards child nodes associated with the IAB node 104, and the IAB-MT may act as a scheduled node towards parent nodes associated with the IAB node 104. That is, an IAB donor may be referred to as a parent node in communication with one or more child nodes (e.g., an IAB donor may relay transmissions for UEs through one or more other IAB nodes 104) . Additionally, or alternatively, an IAB node 104 may also be referred to as a parent node or a child node to other IAB nodes 104, depending on the relay chain or configuration of the AN. Therefore, the IAB-MT entity of IAB nodes 104 may provide a Uu interface for a child IAB node 104 to receive signaling from a parent IAB node 104, and the DU interface (e.g., DUs 165) may provide a Uu interface for a parent IAB node 104 to signal to a child IAB node 104 or UE 115.
For example, IAB node 104 may be referred to as a parent node that supports communications for a child IAB node, or referred to as a child IAB node associated with an IAB donor, or both. The IAB donor may include a CU 160 with a wired or wireless connection (e.g., a backhaul communication link 120) to the core network 130 and may act as parent node to IAB nodes 104. For example, the DU 165 of IAB donor may relay transmissions to UEs 115 through IAB nodes 104, or may directly signal transmissions to a UE 115, or both. The CU 160 of IAB donor may signal communication link establishment via an F1 interface to IAB nodes 104, and the IAB nodes 104 may schedule transmissions (e.g., transmissions to the UEs 115 relayed from the IAB donor) through the DUs 165. That is, data may be relayed to and from IAB nodes 104 via signaling via an NR Uu interface to MT of the IAB node 104. Communications with IAB node 104 may be scheduled by a DU 165 of IAB donor and communications with IAB node 104 may be scheduled by DU 165 of IAB node 104.
In the case of the techniques described herein applied in the context of a disaggregated RAN architecture, one or more components of the disaggregated RAN architecture may be configured to support measurement gap adaptation as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., a base station 140) may additionally, or alternatively, be performed by one or more components of the disaggregated RAN architecture (e.g., IAB nodes 104, DUs 165, CUs 160, RUs 170, RIC 175, SMO 180) .
A UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where the “device” may also be referred to as a unit, a station, a terminal, or a client, among other examples. A UE 115 may also include or may be referred to as a personal electronic device such as a cellular phone, a personal digital assistant (PDA) , a tablet computer, a laptop computer, or a personal computer. In some examples, a UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communications (MTC) device, among other examples, which may be implemented in various objects such as appliances, or vehicles, meters, among other examples.
The UEs 115 described herein may be able to communicate with various types of devices, such as other UEs 115 that may sometimes act as relays as well as the network entities 105 and the network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, as shown in FIG. 1.
The UEs 115 and the network entities 105 may wirelessly communicate with one another via one or more communication links 125 (e.g., an access link) using resources associated with one or more carriers. The term “carrier” may refer to a set of RF spectrum resources having a defined physical layer structure for supporting the communication links 125. For example, a carrier used for a communication link 125 may include a portion of a RF spectrum band (e.g., a bandwidth part (BWP) ) that is operated according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR) . Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information) , control signaling that coordinates operation for the carrier, user data, or other signaling. The wireless communications system 100 may support communication with a UE 115 using carrier aggregation or multi-carrier operation. A UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers. Communication between a network entity 105 and other devices may refer to communication between the devices and any portion (e.g., entity, sub-entity) of a network entity 105. For example, the terms “transmitting, ” “receiving, ” or “communicating, ” when referring to a network entity 105, may refer to any portion of a network entity 105 (e.g., a base station 140, a CU 160, a DU 165, a RU 170) of a RAN communicating with another device (e.g., directly or via one or more other network entities 105) .
In some examples, such as in a carrier aggregation configuration, a carrier may also have acquisition signaling or control signaling that coordinates operations for other carriers. A carrier may be associated with a frequency channel (e.g., an evolved universal mobile telecommunication system terrestrial radio access (E-UTRA) absolute RF channel number (EARFCN) ) and may be identified according to a channel raster for discovery by the UEs 115. A carrier may be operated in a standalone mode, in which
case initial acquisition and connection may be conducted by the UEs 115 via the carrier, or the carrier may be operated in a non-standalone mode, in which case a connection is anchored using a different carrier (e.g., of the same or a different radio access technology) .
The communication links 125 shown in the wireless communications system 100 may include downlink transmissions (e.g., forward link transmissions) from a network entity 105 to a UE 115, uplink transmissions (e.g., return link transmissions) from a UE 115 to a network entity 105, or both, among other configurations of transmissions. Carriers may carry downlink or uplink communications (e.g., in an FDD mode) or may be configured to carry downlink and uplink communications (e.g., in a TDD mode) .
A carrier may be associated with a particular bandwidth of the RF spectrum and, in some examples, the carrier bandwidth may be referred to as a “system bandwidth” of the carrier or the wireless communications system 100. For example, the carrier bandwidth may be one of a set of bandwidths for carriers of a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz) ) . Devices of the wireless communications system 100 (e.g., the network entities 105, the UEs 115, or both) may have hardware configurations that support communications using a particular carrier bandwidth or may be configurable to support communications using one of a set of carrier bandwidths. In some examples, the wireless communications system 100 may include network entities 105 or UEs 115 that support concurrent communications using carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured for operating using portions (e.g., a sub-band, a BWP) or all of a carrier bandwidth.
Signal waveforms transmitted via a carrier may be made up of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM) ) . In a system employing MCM techniques, a resource element may refer to resources of one symbol period (e.g., a duration of one modulation symbol) and one subcarrier, in which case the symbol period and subcarrier spacing may be inversely related. The quantity of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the
modulation scheme, or both) , such that a relatively higher quantity of resource elements (e.g., in a transmission duration) and a relatively higher order of a modulation scheme may correspond to a relatively higher rate of communication. A wireless communications resource may refer to a combination of an RF spectrum resource, a time resource, and a spatial resource (e.g., a spatial layer, a beam) , and the use of multiple spatial resources may increase the data rate or data integrity for communications with a UE 115.
One or more numerologies for a carrier may be supported, and a numerology may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier may be divided into one or more BWPs having the same or different numerologies. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time and communications for the UE 115 may be restricted to one or more active BWPs.
The time intervals for the network entities 105 or the UEs 115 may be expressed in multiples of a basic time unit which may, for example, refer to a sampling period of Ts=1/ (Δfmax·Nf) seconds, for which Δfmax may represent a supported subcarrier spacing, and Nf may represent a supported discrete Fourier transform (DFT) size. Time intervals of a communications resource may be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms) ) . Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023) .
Each frame may include multiple consecutively-numbered subframes or slots, and each subframe or slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a quantity of slots. Alternatively, each frame may include a variable quantity of slots, and the quantity of slots may depend on subcarrier spacing. Each slot may include a quantity of symbol periods (e.g., depending on the length of the cyclic prefix prepended to each symbol period) . In some wireless communications systems 100, a slot may further be divided into multiple mini-slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., Nf) sampling periods. The duration of a symbol period may depend on the subcarrier spacing or frequency band of operation.
A subframe, a slot, a mini-slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communications system 100 and may be referred to as a transmission time interval (TTI) . In some examples, the TTI duration (e.g., a quantity of symbol periods in a TTI) may be variable. Additionally, or alternatively, the smallest scheduling unit of the wireless communications system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs) ) .
Physical channels may be multiplexed for communication using a carrier according to various techniques. A physical control channel and a physical data channel may be multiplexed for signaling via a downlink carrier, for example, using one or more of time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET) ) for a physical control channel may be defined by a set of symbol periods and may extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) may be configured for a set of the UEs 115. For example, one or more of the UEs 115 may monitor or search control regions for control information according to one or more search space sets, and each search space set may include one or multiple control channel candidates in one or more aggregation levels arranged in a cascaded manner. An aggregation level for a control channel candidate may refer to an amount of control channel resources (e.g., control channel elements (CCEs) ) associated with encoded information for a control information format having a given payload size. Search space sets may include common search space sets configured for sending control information to multiple UEs 115 and UE-specific search space sets for sending control information to a specific UE 115.
A network entity 105 may provide communication coverage via one or more cells, for example a macro cell, a small cell, a hot spot, or other types of cells, or any combination thereof. The term “cell” may refer to a logical communication entity used for communication with a network entity 105 (e.g., using a carrier) and may be associated with an identifier for distinguishing neighboring cells (e.g., a physical cell identifier (PCID) , a virtual cell identifier (VCID) , or others) . In some examples, a cell also may refer to a coverage area 110 or a portion of a coverage area 110 (e.g., a sector) over which the logical communication entity operates. Such cells may range from
smaller areas (e.g., a structure, a subset of structure) to larger areas depending on various factors such as the capabilities of the network entity 105. For example, a cell may be or include a building, a subset of a building, or exterior spaces between or overlapping with coverage areas 110, among other examples.
A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by the UEs 115 with service subscriptions with the network provider supporting the macro cell. A small cell may be associated with a lower-powered network entity 105 (e.g., a lower-powered base station 140) , as compared with a macro cell, and a small cell may operate using the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells may provide unrestricted access to the UEs 115 with service subscriptions with the network provider or may provide restricted access to the UEs 115 having an association with the small cell (e.g., the UEs 115 in a closed subscriber group (CSG) , the UEs 115 associated with users in a home or office) . A network entity 105 may support one or multiple cells and may also support communications via the one or more cells using one or multiple component carriers.
In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT) , enhanced mobile broadband (eMBB) ) that may provide access for different types of devices.
In some examples, a network entity 105 (e.g., a base station 140, an RU 170) may be movable and therefore provide communication coverage for a moving coverage area 110. In some examples, different coverage areas 110 associated with different technologies may overlap, but the different coverage areas 110 may be supported by the same network entity 105. In some other examples, the overlapping coverage areas 110 associated with different technologies may be supported by different network entities 105. The wireless communications system 100 may include, for example, a heterogeneous network in which different types of the network entities 105 provide coverage for various coverage areas 110 using the same or different radio access technologies.
The wireless communications system 100 may support synchronous or asynchronous operation. For synchronous operation, network entities 105 (e.g., base stations 140) may have similar frame timings, and transmissions from different network entities 105 may be approximately aligned in time. For asynchronous operation, network entities 105 may have different frame timings, and transmissions from different network entities 105 may, in some examples, not be aligned in time. The techniques described herein may be used for either synchronous or asynchronous operations.
Some UEs 115, such as MTC or IoT devices, may be low cost or low complexity devices and may provide for automated communication between machines (e.g., via Machine-to-Machine (M2M) communication) . M2M communication or MTC may refer to data communication technologies that allow devices to communicate with one another or a network entity 105 (e.g., a base station 140) without human intervention. In some examples, M2M communication or MTC may include communications from devices that integrate sensors or meters to measure or capture information and relay such information to a central server or application program that uses the information or presents the information to humans interacting with the application program. Some UEs 115 may be designed to collect information or enable automated behavior of machines or other devices. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based business charging.
Some UEs 115 may be configured to employ operating modes that reduce power consumption, such as half-duplex communications (e.g., a mode that supports one-way communication via transmission or reception, but not transmission and reception concurrently) . In some examples, half-duplex communications may be performed at a reduced peak rate. Other power conservation techniques for the UEs 115 include entering a power saving deep sleep mode when not engaging in active communications, operating using a limited bandwidth (e.g., according to narrowband communications) , or a combination of these techniques. For example, some UEs 115 may be configured for operation using a narrowband protocol type that is associated
with a defined portion or range (e.g., set of subcarriers or resource blocks (RBs) ) within a carrier, within a guard-band of a carrier, or outside of a carrier.
The wireless communications system 100 may be configured to support ultra-reliable communications or low-latency communications, or various combinations thereof. For example, the wireless communications system 100 may be configured to support ultra-reliable low-latency communications (URLLC) . The UEs 115 may be designed to support ultra-reliable, low-latency, or critical functions. Ultra-reliable communications may include private communication or group communication and may be supported by one or more services such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency may be used interchangeably herein.
In some examples, a UE 115 may be configured to support communicating directly with other UEs 115 via a device-to-device (D2D) communication link 135 (e.g., in accordance with a peer-to-peer (P2P) , D2D, or sidelink protocol) . In some examples, one or more UEs 115 of a group that are performing D2D communications may be within the coverage area 110 of a network entity 105 (e.g., a base station 140, an RU 170) , which may support aspects of such D2D communications being configured by (e.g., scheduled by) the network entity 105. In some examples, one or more UEs 115 of such a group may be outside the coverage area 110 of a network entity 105 or may be otherwise unable to or not configured to receive transmissions from a network entity 105. In some examples, groups of the UEs 115 communicating via D2D communications may support a one-to-many (1: M) system in which each UE 115 transmits to each of the other UEs 115 in the group. In some examples, a network entity 105 may facilitate the scheduling of resources for D2D communications. In some other examples, D2D communications may be carried out between the UEs 115 without an involvement of a network entity 105.
In some systems, a D2D communication link 135 may be an example of a communication channel, such as a sidelink communication channel, between vehicles (e.g., UEs 115) . In some examples, vehicles may communicate using vehicle-to-everything (V2X) communications, vehicle-to-vehicle (V2V) communications, or some
combination of these. A vehicle may signal information related to traffic conditions, signal scheduling, weather, safety, emergencies, or any other information relevant to a V2X system. In some examples, vehicles in a V2X system may communicate with roadside infrastructure, such as roadside units, or with the network via one or more network nodes (e.g., network entities 105, base stations 140, RUs 170) using vehicle-to-network (V2N) communications, or with both.
The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or 5G core (5GC) , which may include at least one control plane entity that manages access and mobility (e.g., a mobility management entity (MME) , an access and mobility management function (AMF) ) and at least one user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW) , a Packet Data Network (PDN) gateway (P-GW) , or a user plane function (UPF) ) . The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for the UEs 115 served by the network entities 105 (e.g., base stations 140) associated with the core network 130. User IP packets may be transferred through the user plane entity, which may provide IP address allocation as well as other functions. The user plane entity may be connected to IP services 150 for one or more network operators. The IP services 150 may include access to the Internet, Intranet (s) , an IP Multimedia Subsystem (IMS) , or a Packet-Switched Streaming Service.
The wireless communications system 100 may operate using one or more frequency bands, which may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz) . Generally, the region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, which may be referred to as clusters, but the waves may penetrate structures sufficiently for a macro cell to provide service to the UEs 115 located indoors. Communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) compared to communications using the smaller frequencies and longer waves of the
high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz.
The wireless communications system 100 may also operate using a super high frequency (SHF) region, which may be in the range of 3 GHz to 30 GHz, also known as the centimeter band, or using an extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) , also known as the millimeter band. In some examples, the wireless communications system 100 may support millimeter wave (mmW) communications between the UEs 115 and the network entities 105 (e.g., base stations 140, RUs 170) , and EHF antennas of the respective devices may be smaller and more closely spaced than UHF antennas. In some examples, such techniques may facilitate using antenna arrays within a device. The propagation of EHF transmissions, however, may be subject to even greater attenuation and shorter range than SHF or UHF transmissions. The techniques disclosed herein may be employed across transmissions that use one or more different frequency regions, and designated use of bands across these frequency regions may differ by country or regulating body.
The wireless communications system 100 may utilize both licensed and unlicensed RF spectrum bands. For example, the wireless communications system 100 may employ License Assisted Access (LAA) , LTE-Unlicensed (LTE-U) radio access technology, or NR technology using an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. While operating using unlicensed RF spectrum bands, devices such as the network entities 105 and the UEs 115 may employ carrier sensing for collision detection and avoidance. In some examples, operations using unlicensed bands may be based on a carrier aggregation configuration in conjunction with component carriers operating using a licensed band (e.g., LAA) . Operations using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.
A network entity 105 (e.g., a base station 140, an RU 170) or a UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of a network entity 105 or a UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base
station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with a network entity 105 may be located at diverse geographic locations. A network entity 105 may include an antenna array with a set of rows and columns of antenna ports that the network entity 105 may use to support beamforming of communications with a UE 115. Likewise, a UE 115 may include one or more antenna arrays that may support various MIMO or beamforming operations. Additionally, or alternatively, an antenna panel may support RF beamforming for a signal transmitted via an antenna port.
The network entities 105 or the UEs 115 may use MIMO communications to exploit multipath signal propagation and increase spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques may be referred to as spatial multiplexing. The multiple signals may, for example, be transmitted by the transmitting device via different antennas or different combinations of antennas. Likewise, the multiple signals may be received by the receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry information associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords) . Different spatial layers may be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) , for which multiple spatial layers are transmitted to the same receiving device, and multiple-user MIMO (MU-MIMO) , for which multiple spatial layers are transmitted to multiple devices.
Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a network entity 105, a UE 115) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining the signals communicated via antenna elements of an antenna array such that some signals propagating along particular orientations with respect to an antenna array experience constructive interference while others experience destructive interference. The adjustment of signals communicated via the antenna elements may include a transmitting device or a receiving device applying amplitude offsets, phase
offsets, or both to signals carried via the antenna elements associated with the device. The adjustments associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g., with respect to the antenna array of the transmitting device or receiving device, or with respect to some other orientation) .
A network entity 105 or a UE 115 may use beam sweeping techniques as part of beamforming operations. For example, a network entity 105 (e.g., a base station 140, an RU 170) may use multiple antennas or antenna arrays (e.g., antenna panels) to conduct beamforming operations for directional communications with a UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted by a network entity 105 multiple times along different directions. For example, the network entity 105 may transmit a signal according to different beamforming weight sets associated with different directions of transmission. Transmissions along different beam directions may be used to identify (e.g., by a transmitting device, such as a network entity 105, or by a receiving device, such as a UE 115) a beam direction for later transmission or reception by the network entity 105.
Some signals, such as data signals associated with a particular receiving device, may be transmitted by transmitting device (e.g., a transmitting network entity 105, a transmitting UE 115) along a single beam direction (e.g., a direction associated with the receiving device, such as a receiving network entity 105 or a receiving UE 115) . In some examples, the beam direction associated with transmissions along a single beam direction may be determined based on a signal that was transmitted along one or more beam directions. For example, a UE 115 may receive one or more of the signals transmitted by the network entity 105 along different directions and may report to the network entity 105 an indication of the signal that the UE 115 received with a highest signal quality or an otherwise acceptable signal quality.
In some examples, transmissions by a device (e.g., by a network entity 105 or a UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or beamforming to generate a combined beam for transmission (e.g., from a network entity 105 to a UE 115) . The UE 115 may report feedback that indicates precoding weights for one or more beam directions, and the
feedback may correspond to a configured set of beams across a system bandwidth or one or more sub-bands. The network entity 105 may transmit a reference signal (e.g., a cell-specific reference signal (CRS) , a channel state information reference signal (CSI-RS) ) , which may be precoded or unprecoded. The UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel type codebook, a linear combination type codebook, a port selection type codebook) . Although these techniques are described with reference to signals transmitted along one or more directions by a network entity 105 (e.g., a base station 140, an RU 170) , a UE 115 may employ similar techniques for transmitting signals multiple times along different directions (e.g., for identifying a beam direction for subsequent transmission or reception by the UE 115) or for transmitting a signal along a single direction (e.g., for transmitting data to a receiving device) .
A receiving device (e.g., a UE 115) may perform reception operations in accordance with multiple receive configurations (e.g., directional listening) when receiving various signals from a transmitting device (e.g., a network entity 105) , such as synchronization signals, reference signals, beam selection signals, or other control signals. For example, a receiving device may perform reception in accordance with multiple receive directions by receiving via different antenna subarrays, by processing received signals according to different antenna subarrays, by receiving according to different receive beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or by processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as “listening” according to different receive configurations or receive directions. In some examples, a receiving device may use a single receive configuration to receive along a single beam direction (e.g., when receiving a data signal) . The single receive configuration may be aligned along a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have a highest signal strength, highest signal-to-noise ratio (SNR) , or otherwise acceptable signal quality based on listening according to multiple beam directions) .
The wireless communications system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, communications at the bearer or PDCP layer may be IP-based. An RLC layer may perform packet segmentation and reassembly to communicate via logical channels. A MAC layer may perform priority handling and multiplexing of logical channels into transport channels. The MAC layer also may implement error detection techniques, error correction techniques, or both to support retransmissions to improve link efficiency. In the control plane, an RRC layer may provide establishment, configuration, and maintenance of an RRC connection between a UE 115 and a network entity 105 or a core network 130 supporting radio bearers for user plane data. A PHY layer may map transport channels to physical channels.
The UEs 115 and the network entities 105 may support retransmissions of data to increase the likelihood that data is received successfully. Hybrid automatic repeat request (HARQ) feedback is one technique for increasing the likelihood that data is received correctly via a communication link (e.g., a communication link 125, a D2D communication link 135) . HARQ may include a combination of error detection (e.g., using a cyclic redundancy check (CRC) ) , forward error correction (FEC) , and retransmission (e.g., automatic repeat request (ARQ) ) . HARQ may improve throughput at the MAC layer in poor radio conditions (e.g., low signal-to-noise conditions) . In some examples, a device may support same-slot HARQ feedback, in which case the device may provide HARQ feedback in a specific slot for data received via a previous symbol in the slot. In some other examples, the device may provide HARQ feedback in a subsequent slot, or according to some other time interval.
In some examples of the wireless communications system 100, a network entity 105 may configure a UE 115 with one or more measurement gaps to perform inter-frequency/RAT measurements, beam measurements, or intra-frequency measurements when an active BWP of a UE 115 does not include an SSB. During a measurement gap, the measurement gap may take priority and a UE 115 may refrain from transmitting any uplink transmissions, receiving any downlink transmissions, or both. Thus, the UE 115 may refrain from transmitting physical uplink control channel (PUCCH) data, sounding reference signals (SRSs) , physical uplink shared channel (PUSCH) data along with refraining from receiving physical downlink control channel
(PDCCH) and physical downlink shared channel (PDSCH) data during a measurement gap occasion. However, the UE 115 may transmit and receive data related to random access channel (RACH) activities during a measurement. Further, if the reception of a CSI-RS overlaps or collides with a measurement gap, the UE 115 may be configured to report the latest CSI report.
Moreover, in some cases, during a measurement gap occasion, a MAC entity of a UE 115, on the serving cell (s) in a corresponding frequency range of the measurement gap occasion configured with a measurement gap configuration (e.g., measGapConfig) , may follow a set of rules. For example, during a measurement gap occasion, the UE 115 may refrain from performing a transmission of HARQ feedback, of an SR, or a CSI, refrain from reporting SRSs, and may refrain from transmitting on the uplink shared channel (UL-SCH) except for Msg3 or the MsgA payload of a random access procedure. Additionally, or alternatively, if the random access response window (e.g., ra-ResponseWindow) , the random access contention resolution timer (e.g., ra-ContentionResolutionTimer) , or the MsgB response window (e.g., msgB-ResponseWindow) are configured and running, the UE 115 a may monitor the PDCCH, otherwise the UE 115 a may refrain from monitoring the PDCCH, and may refrain from receiving transmissions on the downlink shared channel (DL-SCH) .
In cases where a UE 115 is transmitting regular data traffic with relatively loose latency targets or data traffic that can be aligned with a measurement gap pattern, the measurement gaps may refrain from impacting the wireless communications system 100. However, in cases where a UE 115 transmits XR data, the data traffic throughput and latency performance of the wireless communications system 100 may be impacted by one or more measurement gaps. For example, a UE 115 may transmit XR data traffic in a burst fashion and such XR data bursts may collide with one or more measurement gaps of a measurement gap pattern. That is, an XR data burst may collide with the measurement gap where the UE 115 is configured to perform one or more measurements. For example, the UE 115 may transmit a set of XR data to the network entity at a given time. XR data may include VR data, AR data, MR data, and other types of data which may be associated with high reliability and low latency transmissions. In some cases, while the UE 115 and the network entity 105 may adjust the periodicities of one or more measurement gaps, XR data collisions may still occur as the configured
periodicity of measurement gaps as the periodicity of the measurement gaps may be configured to align with a SSB window. Therefore, since XR data may have relatively stringent latency targets and such collisions may be unavoidable, collisions between measurement gaps and the XR data may result in a decrease of reliability and efficiency and an increase of latency within the wireless communications system 100.
Therefore, the techniques of the present disclosure may describe enabling signaling between a network entity 105 and a UE 115 to semi-statically or persistently prioritize XR traffic data over measurement gaps, or vice versa to decrease the impact of measurement gaps on XR data burst transmissions. For example, a UE 115 may receive an indication from a network entity 105 that indicates measurement gap pattern for the UE 115 from a set of pre-configured measurement gap patterns. Following, the UE 115 may receive an indication from the network entity 105 to adapt the measurement gap pattern of the UE 115. For example, the network entity 105 may indicate for the UE 115 to switch from a sparse measurement gap pattern (e.g., a pattern with measurement gaps close together) to a dense measurement gap pattern (e.g., a pattern with measurement gaps far apart) . In another example, the network entity 105 may indicate to the UE 115 to skip one or more measurement gaps or to refrain from skipping one or more measurement gaps. Such indications may be triggered to indicate the measurement gap adaptation, a duration for the adaptation, or both. Further, the network entity 105 may transmit the measurement gap adaptation indication via a DCI message where the adaptation indication is indicated via at least one parameter field of the DCI message. Thus, the UE 115 may operate in accordance with the indicated measurement gap adaptation to enable the wireless communications system 100 in being more reliable and efficient.
FIG. 2 shows an example of a wireless communications system 200 that supports measurement gap adaptation in accordance with one or more aspects of the present disclosure. In some examples, the wireless communications system 200 may implement or be implemented by the wireless communications system 100. For example, the wireless communications system 200 may include a UE 115-a and a network entity 105-a, which may be examples of devices described herein. The UE 115-a may communicate with the network entity 105-a via an uplink communication link 205 and a downlink communication link 210. In some examples, the uplink
communication link 205 and the downlink communication link 210 may be examples of Uu links, sidelink links, backhaul links, D2D links, or some other type of communication links 125 described herein with reference to FIG. 1.
In some examples, the UE 115-a may transmit the XR data bursts 215 (e.g., an XR data burst 215-a, an XR data burst 215-b, an XR data burst 215-c, an XR data burst 215-d, an XR data burst 215-e, an XR data burst 215-f, an XR data burst 215-g, and an XR data burst 215-h) to the network entity 105-a via the uplink communication link 205. In some cases, each XR data burst 215 may be associated with a corresponding XR data message 220 (e.g., an XR data message 220-a, an XR data message 220-b) , an XR data message 225 (e.g., an XR data message 225-a, an XR data message 225-b) , an XR data message 230 (e.g., an XR data message 230-a, an XR data message 230-b, an XR data message 230-c) , an XR data message 235 (e.g., an XR data message 235-a, an XR data message 235-b) , or any combination thereof. For example, the XR data burst 215-a may correspond to the XR data message 220-a. That is, for the XR data burst 215-a, the UE 115-a may transmit the XR data message 220-a to the network entity 105-a. Further, the UE 115-a may be configured with a set of (e.g., one or more) measurement gaps 240 (e.g., a measurement gap 240-a, a measurement gap 240-b, a measurement gap 240-c, a measurement gap 240-d, a measurement gap 240-e, a measurement gap 240-f) .
In some cases, as discussed herein, a measurement gap 240 may collide with the transmission of an XR data burst 215. In some examples, the network entity 105-amay change the periodicity of the measurement gaps 240 and the UE 115-a may change the periodicity of the XR data bursts 215. However, the network entity 105-a may be unable to match periodicity of the measurement gaps 240 to the periodicity of the XR data bursts 215. For example, the periodicity of the measurement gaps 240 (e.g., 20, 40, 80, or 160 ms) may be designed to match the periodicity of an SSB-based radio resource management (RRM) measurement timing configuration (SMTC) window or an SSB window. Further, the periodicity of the XR data traffic of the XR data bursts 215 may typically be between 30, 45, 60, 90, and 120 frames per seconds (fps) that corresponds to a frame periodicity of 33.33, 22.22, 16.66, 11.11, and 8.33 ms. Therefore, collisions between the measurement gaps 240 and the XR data bursts 215 may be unable to be
avoided by the UE 115-a adjusting the offset of the XR data bursts 215 or the network entity 105-a adjusting the offset of the measurement gaps 240.
Further, collisions between the XR data bursts 215 and the measurement gaps 240 may have one or more impacts on the wireless communications system 200. For example, XR data traffic may have a stringent latency target via a packet delay budget (PDB) (e.g., PDB = 10ms) and the network entity 105-a may configure the measurement gaps 240 with a length between 1.5ms to 6ms. Therefore, collisions between the measurement gaps 240 and the XR data bursts 215 may increase the latency of XR data traffic and may force the network to abandon an entire frame. For example, the XR data burst 215-b that corresponds to the XR data message 225-a may completely overlay with the measurement gap 240-b. Thus, a relatively large portion of the XR data message 225-a may be canceled resulting in the UE 115-a having to perform one or more retransmissions thus increasing the latency of the XR data traffic within the wireless communications system 200.
In some examples, a wireless device (e.g., UE 115) may use power-saving procedures to conserve power (e.g., by powering down one or more components of the wireless device, such as a receiver, one or more radio chains, or the like) . As an example, the UE 115-a may use discontinuous reception (DRX) (e.g., connected mode discontinuous reception (CDRX) ) techniques to transition to a sleep state when the UE is not transmitting or receiving data, thereby reducing power consumption of the UE 115-a. Here, the UE 115-a may periodically wake to monitor for indications of incoming data, or wake to transmit uplink data. As shown with reference to FIG. 2, the CDRX cycle may have an ‘ON’s tate where the UE 115-a is awake to transmit the XR data. For example, the XR data message 230-b may be transmitted during an ‘ON’s tate of the UE 115-a. However, in some cases, a portion of the transmission of the XR data message 230-b may collide with the measurement gap 240-f during a first ‘ON’s tate of the UE 115-a. Therefore, the portion of the XR data message 230-b may be canceled and the UE 115-a may have to transmit the remainder of the XR data message 230-b (e.g., the XR data message 230-c) within a separate ‘ON’s tate which may result in an increase of the latency of the XR data transmissions.
In accordance with the techniques of the present disclosure, the network entity 105-a may transmit a message to the UE 115-a on the downlink communication
link 210 to prioritize XR data traffic. In some examples, the network entity 105-a may transmit the message to the UE 115-a semi-statically or semi-persistently to assist the XR service of the UE 115-a and prioritize the XR traffic data over the measurement gaps 240, enabling a flexible dynamic collision handling mechanism for the UE 115-aand the network entity 105-a. For example, the network entity 105-a may transmit signaling to the UE 115-a to dynamically adapt a measurement gap pattern of the UE 115-a to reduce the latency of the XR data traffic. In some cases, the adaptation of the measurement gap pattern of the UE 115-a may include dynamically activating or deactivating one or more measurement gap occasions. In some cases, the network entity 105-a may trigger a measurement gap pattern switch for the UE 115-a instructing the UE to switch from one measurement gap pattern to another.
In some cases, the network entity 105-a may transmit a duration-based or bitmap-based indication to dynamically indicate the UE 115-a to skip one or more measurement gap occasions. For example, if a duration is indicated, the UE 115-a may activate or deactivate the measurement gaps 240 in one or more measurement occasions for the indicated duration. Further, if a bit string is used to indicate the activation or deactivation of the measurement gaps 240, the UE 115-a may use the bit string to indicate a measurement gap 240 that is disconnected. In some examples, to indicate the measurement gap 240 activation or deactivation, the network entity 105-a may transmit a DCI message to notify the information to the UE 115-a. In some cases, the network entity 105-a may transmit the information within a format of the DCI. In some other cases, the network entity 105-a may reinterpret or reuse a format or parameter of the DCI to indicate the activation or deactivation information. Additionally, or alternatively, in the case that a measurement gap 240 duration overlaps with a CDRX-ON state and a XR data burst 215, part of the measurement gap 240 may be indicated as deactivated for a XR traffic transmission while the remaining part of the measurement gap 240 can be used as a measurement gap 240 that is activated. Examples of such messaging and signaling are described elsewhere herein, such as with reference to FIGs. 3A through 3C.
FIG. 3A shows an example of a signaling diagram 300 that supports measurement gap adaptation in accordance with one or more aspects of the present disclosure. In some examples, the signaling diagram 300 may implement or be
implemented by the wireless communications system 100, the wireless communications system 200, or both. Further, the signaling diagram 300 may illustrate a UE 115 that is configured with a set of (e.g., a set of one or more) measurement gap patterns 305 (e.g., a measurement gap pattern 305-a and a measurement gap pattern 305-b) for the UE 115 to operate during a measurement gap 310 (e.g., a measurement gap 310-a, a measurement gap 310-b, a measurement gap 310-c, and a measurement gap 310-d) . In addition, the signaling diagram 300 may illustrate a UE 115 receiving a DCI message 315 (e.g., a DCI message 315-a) indicating an adaption to a measurement gap pattern 305.
In some examples, a UE 115, may receive a first control message from a network entity 105 that may indicate a set of (e.g., a set of one or more) measurement gap patterns 305 including the measurement gap pattern 305-a and the measurement gap pattern 305-b. In some cases, the first control message may be an example of an RRC message that also configures the UE 115 with a measurement gap pattern 305 of the set of measurement gap patterns 305. That is, the network entity 105 may configure the UE 115 with the measurement gap pattern 305-a to operate in accordance with.
As illustrated in FIG. 3A, the UE 115 may be configured with the measurement gap pattern 305-a and may use the measurement gap 310-a and the measurement gap 310-b. That is, the UE 115 may perform one or more measurements within the measurement gap 310-a and the measurement gap 310-b. In some examples, XR data transmissions may collide with the measurement gaps 310 of the measurement gap pattern 305-a. Thus, the network entity 105 may transmit the DCI message 315-a to the UE 115 to perform a measurement gap pattern 305 switch from the measurement gap pattern 305-a to the measurement gap pattern 305-b. Using the DCI message 315-amay allow the UE 115 the flexibility to switch between measurement gap patterns 305 with relatively low signaling overhead.
For example, the DCI message 315-a from the network entity 105 may indicate for the UE 115 to switch between the measurement gap pattern 305-a and the measurement gap pattern 305-b. In some cases, the measurement gap pattern 305 pattern switch may indicate for the UE 115 to switch between a measurement gap pattern 305 that is dense (e.g., the measurement gap pattern 305-a) and a measurement gap pattern 305 that is sparse (e.g., the measurement gap pattern 305-b) . In some
examples, the DCI message 315-a may be within a format (e.g., DCI format 0_1, 1_1, 0_2, 1_2, or any combination thereof) for data scheduling that includes a measurement gap pattern 305 adaptation indication field that indicates (e.g., triggers) a switch between the measurement gap patterns 305. For example, the DCI message 315-a may indicate for the UE 115 to switch to one of the other measurement gap patterns indicated via an RRC message from the network entity 105 that configured the set of measurement gap patterns 305. In some cases, the measurement gap patterns 305 may differ from each other by being associated with measurement gap 310 periodicities that are different. For example, the measurement gap pattern 305-a may have a periodicity of 20ms between the measurement gap 310-a and the measurement gap 310-b. Further, the measurement gap pattern 305-b may have a periodicity of 80ms between the measurement gap 310-c and the measurement gap 310-d.
In some examples, the measurement gap pattern 305 indication field of the DCI message 315-a may indicate the measurement gap pattern 305 within a bit of a bitmap. For example, as illustrated in Tables 1 and 2 below, the indication field may use one or more bits to indicate a measurement gap pattern 305 that a UE 115 should switch to or use. In some cases, the bits may indicate a binary number that corresponds to an index or identifier for a measurement gap pattern 305 stored at the UE 115. Thus, the UE 115 may use the indication field from the DCI message 315-a to determine the measurement gap pattern 305 the UE 115 should use.
Table 1
Table 2
Further, in some examples, the indication of the DCI message 315-a may also indicate a duration for the UE 115 to stay in a measurement gap pattern 305 (e.g., a target pattern) . For example, a UE 115 may switch from the measurement gap pattern 305-a to the measurement gap pattern 305-b for a duration (e.g., a period of time) . Thus, the UE 115 may operate in accordance with the measurement gap pattern 305-b for the duration based on the measurement gap pattern 305 switch. After expiration of the duration the UE 115 may switch from the measurement gap pattern 305-b back to the measurement gap pattern 305-a. Thus, the indication field of the DCI message 315-amay also indicate the duration for the UE 115 to use a measurement gap pattern 305. For example, as shown below in Table 3, a first bit of int indication field may be used to indicate a measurement gap pattern 305 and a second bit may be used to indicate a duration for the UE 115 to use the measurement gap pattern 305. Further, in the example of Table 3, if the first bit (e.g., the most significant bit (MSB) ) of the indication field is a 0, the UE 115 may use a the measurement gap pattern 305-a, and if the first bit of the indication field is a 1, the UE 115 may use the measurement gap pattern 305-b. Similarly, if the second bit (e.g., the least significant bit (LSB) ) of the indication field is a 0, the UE 115 may use a measurement gap pattern (e.g., the measurement gap pattern 305-a or the measurement gap pattern 305-b) for a first duration (e.g., T0) , and if the second bit of the indication field is a 1, the UE 115 may use the measurement gap pattern 305 for a second duration (e.g., T1. Further, the indication field may include more than two bits such that additional measurement gap patterns 305 and additional durations can be indicated via the DCI message 315-a.
Table 3
Additionally, or alternatively, the network entity 105 may indicate the measurement gap pattern 305 switch to the UE 115 via an existing parameter of the DCI
message 315-a. For example, the network entity 105 reuse a parameter of the DCI message 315-a (e.g., switchTriggerToAddModList) of a DCI message 315 format (e.g., DCI format 2_0) that is for search space set group switching. Further, in some examples, the format of the DCI message 315-a may be a group common message format (e.g., a group common DCI) . In some cases, the parameter generally may be a higher layer parameter of a DCI message 315 that, if configured, indicates a search space set group switching flag. The parameter may indicate a search space set group switching flag from 1 to M. Thus, similar to the network entity 105 indicating the search space set group switching via a DCI message 315, the network entity 105 may reuse the search space set group switching parameter to indicate a measurement gap pattern 305 switch. Further, the network entity may reuse a bitmap from an RRC reconfiguration message (e.g., RRCReconfiguration) to indicate an index of a measurement gap pattern 305 (e.g., a target pattern) the UE 115 should switch to and use. Thus, after the UE 115 receives the DCI message 315-a indication that is reinterpreted, the UE 115 may switch to the indicated measurement gap pattern index as shown below in Table 4.
Table 4
In some examples, instead of reusing a parameter of a DCI message 315, the network entity 105 may add a parameter that is designed for indicating measurement gap pattern 305 switching (e.g., MGswitchTriggerToAddModList) to the DCI message 315-a. Similarly, a network entity 105 may include such parameter in a group common DCI (e.g., DCI 2_0) . Thus, in some cases, one or more UEs 115 may receive the DCI message 315-a (e.g., a group of UEs 115 with the same UE 115 vendor or with the same UE 115 manufacturer or type) . Further, the network entity 105 may use the parameter designed for the measurement gap switching indications in a similar fashion as the parameter designed for the search space set group switching indication. That is, the
bitmap of the parameter may reuse the bitmap from the RRC reconfiguration message to indicate the measurement gap pattern 305 index and the UE 115 may switch to the indicated measurement pattern 305 index as indicated and shown in Table 4.
Thus, the UE 115 may use the DCI message 315-a to receive an indication of an adaption to the measurement gap pattern 305 configured for the UE 115 where the adaption includes a switch from the measurement gap pattern 305-a (e.g., a first pattern) to the measurement gap pattern 305-b (e.g., a second pattern) . The UE 115 may then operate in accordance with the adaption to the configured measurement gap pattern 305 during a measurement gap 310 occasion. As such, in some cases, the UE 115 may be capable of prioritizing the transmission of XR data over measurement gaps by switching to a measurement gap pattern 305 where measurement gap 310 occasions are less frequent (e.g., the measurement gap pattern 305-b) . In some other cases, the UE 115 may be capable of prioritizing the measurement gaps 310 over the transmission of XR data by switching to a measurement gap pattern 305 where measurement gap 310 occasions are more frequent (e.g., the measurement gap pattern 305-a) . The measurement gap pattern 305 switching that is indicated via the DCI message 315-amay further enable the UE 115 to prioritize XR data transmissions to reduce latency or to prioritize measurement gaps 310 when one or more synchronization procedures are performed to improve communications within a wireless communications network. Therefore, then measurement gap pattern 305 switch indication via the DCI message 315-a may improve the operations of a wireless communications system by reducing the impact of measurement gaps 310 on XR data transmissions. Further uses of a DCI message to indicate an adaptation to a measurement gap pattern are described elsewhere herein, such as with reference to FIGs. 3B and 3C.
FIG. 3B shows an example of a signaling diagram 301 that supports measurement gap adaptation in accordance with one or more aspects of the present disclosure. In some examples, the signaling diagram 301 may implement or be implemented by the wireless communications system 100, the wireless communications system 200, or both. Further, the signaling diagram 301 may illustrate a UE 115 that is configured with a set of (e.g., a set of one or more) measurement gap patterns 305 (e.g., a measurement gap pattern 305-c and a measurement gap pattern 305-d) for the UE 115 to operate during a measurement gap 310 (e.g., a measurement gap 310-e, a
measurement gap 310-f, a measurement gap 310-g, and a measurement gap 310-h) . In addition, the signaling diagram 301 may illustrate a UE 115 receiving a DCI message 315 (e.g., a DCI message 315-b) indicating an adaption to a measurement gap pattern 305.
In some examples, as described with reference to FIG. 3A, a UE 115, may receive a first control message (e.g., an RRC message) from a network entity 105 that indicates a set of (e.g., a set of one or more) measurement gap patterns 305 including the measurement gap pattern 305-c and the measurement gap pattern 305-d.
As illustrated in FIG. 3B, the UE 115 may be configured with the measurement gap pattern 305-c and may use the measurement gap 310-e and the measurement gap 310-f. That is, the UE 115 may perform one or more measurements within the measurement gap 310-e and the measurement gap 310-f. In some examples, XR data transmissions may collide with the measurement gaps 310 of the measurement gap pattern 305-c. Thus, the network entity 105 may transmit the DCI message 315-b to the UE 115 to perform a measurement gap pattern 305 switch from the measurement gap pattern 305-c to the measurement gap pattern 305-d.
In some examples, the DCI message 315-b may indicate for the UE 115 to adapt the measurement gap pattern 305 such that the UE 115 skips a set of (e.g., one or more) measurement gaps 310. For example, the DCI message 315-b may have a data scheduling DCI format (e.g., DCI format 0_1, 1_1, 0_2, and 1_2) that includes a measurement gap 310 adaptation indication field that triggers the measurement gap 310 skips. In some cases, the control message sent to the UE 115 that configures the UE 115 with a measurement gap pattern 305 may configure UE 115 to perform measurements within the measurement gaps 310 (e.g., the measurement gap 310-e and the measurement gap 310-f) . Thus, the DCI message 315-b may indicate for the UE 115 to skip the measurement gap 310-g and the measurement gap 310-h. In some cases, the measurement gap pattern 305-d may be a measurement gap pattern 305 where the UE 115 skips the measurement gaps 310. In some other cases, the measurement gap pattern 305-d may the same as the measurement gap pattern 305-c and the DCI message 315-b indicates for the UE 115 to skip the measurement gaps 310 (e.g., the measurement gap 310-g and the measurement gap 310-h) . For example, as shown in Table 5, the indication field may include a bit that indicates for the UE 115 to either perform
measurements within measurement gaps 310 or to skip measurement gaps 310 that are configured.
Table 5
Further, the indication of the DCI message 315-b may also indicate a duration for the UE 115 to skip the measurement gaps 310 if the UE 115 is configured by default (e.g., via the RRC message) to perform measurements within the measurement gaps 310. In some cases, one or more duration options (e.g., T0, T1, T2) may be configured via the initial control message (e.g., RRC message) that configured the UE 115 with the set of (e.g., the set of one or more) measurement gap patterns 305 or via a different control message (e.g., an RRC or MAC-CE message) . Further, each duration option may correspond to a unique identifier within the indication field of the DCI message 315-b. For example, as shown below in Table 6, a bit value (e.g., a number in binary base 2) may be assigned to each duration such that the UE 115 skips the measurement gaps 310 for the indicated duration.
Table 6
Thus, as shown in Table 6, each duration may be assigned a unique identifier within the DCI message 315-b. For example, if the indication field of the DCI message 315-b indicates a 2 (e.g., ‘10’ in binary base 2) , the UE 115 may skip performing measurements within the measurement gaps 310 (e.g., the measurement gap 310-g and
the measurement gap 310-h) for the duration corresponding to the value of the indication field in the DCI message 315-b (e.g., T1) .
In some cases, the duration for the measurement gap 310 skipping may also be indicated via a UE 115 DCI message 315 that is a group common DCI (e.g., the DCI message 315-b) that supports the indication of a duration. For example, a DCI message 315 format (e.g., DCI 2_0) may indicate a channel occupancy (CO) duration. In some cases, a network entity 105 may configure a DCI message 315 with a cyclic redundancy check (CRC) and scramble the DCI message 315 with a slot format indication (SFI) radio network temporary identifier (SFI-RNTI) . Within the DCI message 315 format, if a first higher layer parameter (e.g., slotFormatCombToAddModList) is configured, a slot format indicator may be indicated (e.g., from slot format indicator 1 to slot format indicator N) . If a second higher later parameter (e.g., availableRB-SetsToAddModList) is configured, an available RB set indicator may be indicated (e.g., from an available RB set indicator 1 to an available RB set indicator N1) . Further, the DCI message 315 may include a third higher layer parameter (e.g., co-DurationPerCellToAddModList) that is configured to indicate a CO time (COT) duration indicator (e.g., from a COT duration indicator 1 to a COT duration indicator N2) .
As such, the duration for the UE 115 to switch measurement gap patterns 305 or to skip measurement gaps 310 for may be indicated via a DCI message 315 that is a non-scheduling message (e.g., the measurement gap pattern 305-b) . The DCI message 315-b may be a UE 115 DCI message 315 that is a group common DCI and can either use a DCI message 315 format that is different or reuse a DCI message 315 format that reinterprets the COT duration field described herein. That is, a duration of the adaptation to a measurement gap pattern 305 may be indicated via a parameter of the DCI message 315-b that is associated with COT durations. In some cases, different COT durations and bit sizes for indicating the one or more durations may be configured via the initial control message (e.g., the RRC message) . Therefore, the COT duration field of the DCI message 315-b, which is a bitmap including one or more bits, may be reused to indicate measurement gap 310 activations or deactivations.
In some cases, the COT duration field may indicate a duration for the UE 115 to skip the measurement gaps 310 for. In some other cases, the COT duration field may indicate a duration for the UE 115 to switch measurement gap patterns 305 for, as
described with reference to FIG. 3A. Additionally, or alternatively, the COT duration field of the DCI message 315-b may include a single bit where a value of 1 indicates that the COT duration field can be reused to indicate a measurement gap 310 or measurement gap pattern 305 activation. Thus, a value of 0 may indicate that the COT duration field can be reused to indicate a measurement gap 310 or measurement gap pattern 305 deactivation.
In another example, a DCI message 315 format (e.g., DCI message 315 format 2_4) that is used to cancel PUSCH or SRS transmissions for a UE 115 may be used to dynamically deactivate the measurement gaps 310. In some cases, the DCI message 315 format may indicate the cancellation of an uplink transmission at a physical RB (PRB) level and a symbol-level. Thus, in the case where a UE 115 is configured with a CDRX cycle for the transmission of XR data, as described with reference to FIG. 2, where a part of a measurement gap 310 may collide with an XR data transmission, a portion of a measurement gap 310 may be canceled. Therefore, a network entity 105 may indicate the adaptation to a measurement gap pattern 305 (e.g., the measurement gap 310-c) via an uplink data transmission cancelation message (e.g., the DCI message 315-b) . Further, the adaptation may include a cancelation to at least a portion of a measurement gap 310 of a measurement gap 310 occasion that overlaps with the traffic (e.g., data traffic) of the UE 115.
Moreover, since a portion of the measurement gap pattern 305 may overlap with the CDRX cycle ON state and the XR data traffic, the DCI message 315-b may cancel the overlapping portion of the measurement gap 310 occasion. For example, the uplink transmission cancellation indication may be reused to indicate the slots, symbols, or both, of a measurement gap 310 occasion to be canceled. Therefore, the XR traffic may be transmitted during the CDRX cycle ON state of the UE 115 and the UE 115 may perform one or more measurements within the remaining symbols of the measurement gap 310 occasion. Further, in some cases, there may be relatively short interval between the deactivation or activation of a measurement gap 310 for radio frequency tuning.
In some other cases, a network entity 105 may use format of a DCI message 315 (e.g., DCI 2_6) associated with indicating the dormancy of a secondary cell for power savings for one or more UEs 115 to indicate the deactivation of the measurement
gaps 310. For example, the DCI message 315-b may include a bitmap that indicates whether a respective secondary cell should go into a dormant state (e.g., an OFF or sleep state) . Therefore, the network entity 105 and the UE 115 may reinterpret the bitmap to dynamically deactivate the measurement gaps 310 within a measurement gap 310 occasion. Further, the bitmap may also be used to indicate the deactivation or activation of a measurement gap pattern 305 as described with reference to FIG. 3A.
Additionally, or alternatively, the DCI message 315-b may indicate for the UE 115 to switch to a measurement gap pattern 305 that excludes measurement gap 310 occasions. The measurement gap pattern 305 may be defined by the RRC message that indicates the set of (e.g., a set of one or more) measurement gap patterns 305 the UE 115 can be configured with such that the measurement gap pattern 305 is assigned a measurement gap pattern 305 index. For example, as described with reference to FIG. 3A, the DCI message 315-b may indicate for the UE 115 to switch from the measurement gap pattern 305-c to the measurement gap pattern 305-d where the measurement gap pattern 305-d excludes measurement gap 310 occasions. Thus, the UE 115 may refrain from performing measurements during the measurement gap 310-g and the measurement gap 310-h based on the measurement gap pattern 305-d excluding measurement gaps 310. Therefore, the UE 115 may receive the DCI message 315-b to receive an indication to skip the measurement gaps 310. Further uses of the DCI message 315 for measurement gap pattern adaptations are described elsewhere herein, such as with reference to FIG. 3C.
FIG. 3C shows an example of a signaling diagram 302 that supports measurement gap adaptation in accordance with one or more aspects of the present disclosure. In some examples, the signaling diagram 302 may implement or be implemented by the wireless communications system 100, the wireless communications system 200, or both. Further, the signaling diagram 302 may illustrate a UE 115 that is configured with a set of (e.g., a set of one or more) measurement gap patterns 305 (e.g., a measurement gap pattern 305-e and a measurement gap pattern 305-f) for the UE 115 to operate during a set of (e.g., one or more) measurement gaps 310 (e.g., a measurement gap 310-i, a measurement gap 310-j, a measurement 310-k, and a measurement gap 310-m) . In addition, the signaling diagram 301 may illustrate a UE
115 receiving a DCI message 315 (e.g., a DCI message 315-c) indicating an adaption to a measurement gap pattern 305.
In some examples, as described with reference to FIG. 3A, a UE 115, may receive a first control message (e.g., an RRC message) from a network entity 105 that indicates a set of (e.g., a set of one or more) measurement gap patterns 305 including the measurement gap pattern 305-e and the measurement gap pattern 305-f.
In some examples, the RRC message may indicate that a measurement gap 310 configuration is disabled by default. That is, the UE 115 may refrain from performing one or more measurements during measurement gaps 310 until indicated otherwise. As illustrated in FIG. 3C, the UE 115 may be configured with the measurement gap pattern 305-e and operate in accordance with the measurement gap pattern 305-e. That is, the UE 115 may refrain from performing one or more measurements within the measurement gap 310-i and the measurement gap 310-j.
In some cases, a network entity 105 may transmit the DCI message 315-c to the UE 115 to indicate an adaptation to the measurement gap pattern 305-e. Such adaptation may schedule the measurement gaps 310 within the measurement gap pattern 305-f. Thus, the UE 115 may operate in accordance with the measurement gap pattern 305-f. In some examples, as shown in Table 5, the DCI message 315-c may include an indication field that can indicate for whether the UE 115 should skip the measurement gaps 310. In such cases, the UE 115 may be preconfigured to skip the measurement gaps 310 and the DCI message 315-c may indicate that the UE 115 should refrain from skipping the measurement gaps 310. Further, as shown in Table 6, the DCI message 315-c may also indicate the duration for which the UE 115 should refrain from skipping measurement gaps 310.
Such indications via the DCI message 315 described with reference to FIGs. 3A through 3C may thus decrease the impact of the measurement gaps 310 on the transmission of data. Specifically, when the UE 115 is transmitting XR data, the data traffic may be associated with relatively stringent latency targets that can be disrupted by the measurement gaps 310. Thus, the network entity 105 and the UE 115 may use the techniques of the present disclosure to prevent such disruptions and ensure that the UE 115 can efficiently and accurately transmit XR data. Further descriptions of the
techniques of th present disclosure are described elsewhere herein, such as with reference to FIG. 4.
FIG. 4 shows an example of a process flow 400 that supports measurement gap adaptation in accordance with one or more aspects of the present disclosure. In some examples, the process flow 400 may implement or be implemented by the wireless communications system 100, the signaling diagram 300, the signaling diagram 301, the signaling diagram 302, or any combination thereof. For example, the process flow 400 may include a UE 115-b and a network entity 105-b, which may be examples of devices described herein with reference to FIG. 1.
In the following description of the process flow 400, the operations between the UE 115-b and the network entity 105-b may be performed in different orders or at different times. Some operations may also be left out of the process flow 400, or other operations may be added. Although the UE 115-b and the network entity 105-b are shown performing the operations of the process flow 400, some aspects of some operations may also be performed by one or more other wireless devices.
At 405, the UE 115-b may receive, from the network entity 105-b, a control message (e.g., a second control message) that indicates a set of one or more measurement gap patterns for the UE 115-b. At 410, the UE 115-b may receive, from the network entity 105-b a control message, that is different from or the same as the control message received at 405, that may indicate a first measurement gap pattern for the UE 115-b from the set of one or more measurement gap patterns.
At 415, the UE 115-b may receive, from the network entity 105-b, a message indicating an adaption to the first measurement gap pattern based on a latency target associated with the traffic for the UE 115-b. For example, XR data traffic may be associated with a packet delay budget that includes a latency target for the XR data traffic. Further, the adaptation may include an adjustment of one or more UE 115 operational parameters associated with the first measurement gap pattern or a switch from the first measurement gap pattern to a second measurement gap pattern that is included within the set of one or more measurement gap patterns for the UE 115-b. In some examples, the UE 115-b may receive, from the network entity 105-b, a parameter via the message that is associated with search space set group switching, where the
adaptation to the first measurement gap pattern is indicated via the parameter that is associated with search space set grouping. In some other examples, the UE 115-b may receive, from the network entity 105-b, a parameter via the message that is associated with measurement gap pattern switching, where the adaptation to the first measurement gap pattern is indicated via the parameter that is associated with search space set grouping. Further, in some cases, the message may be a group common control message. Moreover, the parameter of the message that is associated with the measurement gap pattern switching may be for a respective cell of a plurality of cells.
In another example, the UE 115-b may receive, from the network entity 105-b, an indication via the message to perform the switch from the first measurement gap pattern to the second measurement gap pattern. In some cases, the second measurement gap pattern included in the set of one or more measurement gap patterns may exclude measurement gap occasions. Thus, the UE 115-b may refrain from performing measurements at 425 during a measurement gap pattern based on the second measurement gap pattern excluding the measurement gap occasions.
Further, the UE 115-b may receive, from the network entity 105-b, a parameter via the message that is associated with channel occupancy time durations. Thus, a duration of the adaptation to the first measurement gap may be indicated via the parameter that is associated with channel occupancy time durations. In some cases, the UE 115-b may receive an uplink transmission cancellation indication via the message where the adaptation to the first measurement gap pattern is indicated via the uplink transmission cancellation indication. Moreover, the adaptation to the first measurement gap pattern may include a cancelation of at least a portion of a respective measurement gap occasion based on the portion of the respective measurement gap occasion overlapping with the traffic for the UE. In some other cases, the UE 115-b may receive, from the network entity 105-b, an indication of a dormancy of a secondary cell via the message where the adaptation to the first measurement gap is based on the indication of the dormancy.
Additionally, or alternatively, the message from the network entity 105-b that indicated the adaptation to the first measurement gap pattern may include a bitmap that indicated the adaptation. Further, the one or more UE 115 operation parameters may include a periodicity of a set of measurement gap occasions such that the
adaptation to the first measurement gap pattern includes an adjustment to the periodicity of the set of measurement gap occasions for the first measurement gap pattern. In addition, the message that indicates the adaptation may include a duration for the adjustment to the one or more UE 115 operational parameters, a duration for the measurement gap pattern switch, a duration to skip one or more measurement gaps, or any combination thereof. Further, the duration may indicate a quantity of measurement gap occasions of a set of measurement gap occasions for the UE 115-b to skip

Disk and disc, as used herein, include CD, laser disc, optical disc, digital versatile disc (DVD) , floppy disk and Blu-ray disc. Disks may reproduce data magnetically, and discs may reproduce data optically using lasers. Combinations of the above are also included within the scope of computer-readable media. Any functions or operations described herein as being capable of being performed by a memory may be performed by multiple memories that, individually or collectively, are capable of performing the described functions or operations.
As used herein, including in the claims, “or” as used in a list of items (e.g., a list of items prefaced by a phrase such as “at least one of” or “one or more of” ) indicates an inclusive list such that, for example, a list of at least one of A, B, or C means A or B or C or AB or AC or BC or ABC (i.e., A and B and C) . Also, as used herein, the phrase “based on” shall not be construed as a reference to a closed set of conditions. For example, an example step that is described as “based on condition A” may be based on both a condition A and a condition B without departing from the scope of the present disclosure. In other words, as used herein, the phrase “based on” shall be construed in the same manner as the phrase “based at least in part on. ”
As used herein, including in the claims, the article “a” before a noun is open-ended and understood to refer to “at least one” of those nouns or “one or more” of those nouns. Thus, the terms “a, ” “at least one, ” “one or more, ” “at least one of one or more” may be interchangeable. For example, if a claim recites “a component” that performs one or more functions, each of the individual functions may be performed by a single component or by any combination of multiple components. Thus, the term “acomponent” having characteristics or performing functions may refer to “at least one of one or more components” having a particular characteristic or performing a particular function. Subsequent reference to a component introduced with the article “a” using the
terms “the” or “said” may refer to any or all of the one or more components. For example, a component introduced with the article “a” may be understood to mean “one or more components, ” and referring to “the component” subsequently in the claims may be understood to be equivalent to referring to “at least one of the one or more components. ” Similarly, subsequent reference to a component introduced as “one or more components” using the terms “the” or “said” may refer to any or all of the one or more components. For example, referring to “the one or more components” subsequently in the claims may be understood to be equivalent to referring to “at least one of the one or more components. ”
The term “determine” or “determining” encompasses a variety of actions and, therefore, “determining” can include calculating, computing, processing, deriving, investigating, looking up (such as via looking up in a table, a database or another data structure) , ascertaining and the like. Also, “determining” can include receiving (e.g., receiving information) , accessing (e.g., accessing data stored in memory) and the like. Also, “determining” can include resolving, obtaining, selecting, choosing, establishing, and other such similar actions.
In the appended figures, similar components or features may have the same reference label. Further, various components of the same type may be distinguished by following the reference label by a dash and a second label that distinguishes among the similar components. If just the first reference label is used in the specification, the description is applicable to any one of the similar components having the same first reference label irrespective of the second reference label, or other subsequent reference label.
The description set forth herein, in connection with the appended drawings, describes example configurations and does not represent all the examples that may be implemented or that are within the scope of the claims. The term “example” used herein means “serving as an example, instance, or illustration, ” and not “preferred” or “advantageous over other examples. ” The detailed description includes specific details for the purpose of providing an understanding of the described techniques. These techniques, however, may be practiced without these specific details. In some instances, known structures and devices are shown in block diagram form in order to avoid obscuring the concepts of the described examples.
The description herein is provided to enable a person having ordinary skill in the art to make or use the disclosure. Various modifications to the disclosure will be apparent to a person having ordinary skill in the art, and the generic principles defined herein may be applied to other variations without departing from the scope of the disclosure. Thus, the disclosure is not limited to the examples and designs described herein but is to be accorded the broadest scope consistent with the principles and novel features disclosed herein.
