Description

HANDLING COLLISION IN MEASUREMENT GAP

TECHNICAL FIELD

The present disclosure relates to wireless communications, and more specifically to a user equipment (UE) , a base station (BS) , methods, apparatuses, and computer readable medium for handling collision in a measurement gap.

BACKGROUND

A wireless communications system may include one or multiple network communication devices, such as base stations, which may be otherwise known as an eNodeB (eNB) , a next-generation NodeB (gNB) , or other suitable terminology. Each network communication devices, such as a base station may support wireless communications for one or multiple user communication devices, which may be otherwise known as user equipment (UE) , or other suitable terminology. The wireless communications system may support wireless communications with one or multiple user communication devices by utilizing resources of the wireless communication system (e.g., time resources (e.g., symbols, slots, subframes, frames, or the like) or frequency resources (e.g., subcarriers, carriers) . Additionally, the wireless communications system may support wireless communications across various radio access technologies including third generation (3G) radio access technology, fourth generation (4G) radio access technology, fifth generation (5G) radio access technology, among other suitable radio access technologies beyond 5G (e.g., sixth generation (6G) ) .

For supporting extended reality (XR) services which requires lower latency, it is proposed to enable transmission or reception during gaps/restrictions for radio resource management (RRM) . Therefore, a study to choose a channel that can be transmitted or received during the measurement gap is needed, to avoid the collision of different channels.

FIG. 1 illustrates an example of a wireless communications system 100 in which some embodiments of the present disclosure can be implemented. The wireless communications system 100 may include one or more network entities 102 (also referred to as network equipment (NE) ) , one or more UEs 104, a core network 106, and a packet data network 108. The wireless communications system 100 may support various radio access technologies. In some implementations, the wireless communications system 100 may be a 4G network, such as a long term evolution (LTE) network or an LTE-Advanced (LTE-A) network. In some other implementations, the wireless communications system 100 may be a 5G network, such as a new radio (NR) network. In other implementations, the wireless communications system 100 may be a combination of a 4G network and a 5G network, or other suitable radio access technology including Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi) , IEEE 802.16 (WiMAX) , IEEE 802.20. The wireless communications system 100 may support radio access technologies beyond 5G. Additionally, the wireless communications system 100 may support technologies, such as time division multiple access (TDMA) , frequency division multiple access (FDMA) , or code division multiple access (CDMA) , etc.

The one or more network entities 102 may be dispersed throughout a geographic region to form the wireless communications system 100. One or more of the network entities 102 described herein may be or include or may be referred to as a network node, a base station, a network element, a radio access network (RAN) , a base transceiver station, an access point, a NodeB, an eNodeB (eNB) , a next-generation NodeB (gNB) , or other suitable terminology. A network entity 102 and a UE 104 may communicate via a communication link 110, which may be a wireless or wired connection. For example, a network entity 102 and a UE 104 may perform wireless communication (e.g., receive signaling, transmit signaling) over a Uu interface.

A network entity 102 may provide a geographic coverage area 112 for which the network entity 102 may support services (e.g., voice, video, packet data, message, broadcast, etc. ) for one or more UEs 104 within the geographic coverage area 112. For example, a network entity 102 and a UE 104 may support wireless communication of signals related to services (e.g., voice, video, packet data, messaging, broadcast, etc. ) according to one or multiple radio access technologies. In some implementations, a network entity 102 may be moveable, for example, a satellite associated with a non-terrestrial network. In some implementations, different geographic coverage areas 112 associated with the same or different radio access technologies may overlap, but the different geographic coverage areas 112 may be associated with different network entities 102. Information and signals described herein may be represented using any of a variety of different technologies and techniques. For example, data, instructions, commands, information, signals, bits, symbols, and chips that may be referenced throughout the description may be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof.

The one or more UEs 104 may be dispersed throughout a geographic region of the wireless communications system 100. A UE 104 may include or may be referred to as a mobile device, a wireless device, a remote device, a remote unit, a handheld device, or a subscriber device, or some other suitable terminology. In some implementations, the UE 104 may be referred to as a unit, a station, a terminal, or a client, among other examples. Additionally, or alternatively, the UE 104 may be referred to as an Internet-of-Things (IoT) device, an Internet-of-Everything (IoE) device, or machine-type communication (MTC) device, among other examples. In some implementations, a UE 104 may be stationary in the wireless communications system 100. In some other implementations, a UE 104 may be mobile in the wireless communications system 100.

The one or more UEs 104 may be devices in different forms or having different capabilities. Some examples of UEs 104 are illustrated in FIG. 1. A UE 104 may be capable of communicating with various types of devices, such as the network entities 102, other UEs 104, or network equipment (e.g., the core network 106, the packet data network 108, a relay device, an integrated access and backhaul (IAB) node, or another network equipment) , as shown in FIG. 1. Additionally, or alternatively, a UE 104 may support communication with other network entities 102 or UEs 104, which may act as relays in the wireless communications system 100.

A UE 104 may also be able to support wireless communication directly with other UEs 104 over a communication link 114. For example, a UE 104 may support wireless communication directly with another UE 104 over a device-to-device (D2D) communication link. In some implementations, such as vehicle-to-vehicle (V2V) deployments, vehicle-to-everything (V2X) deployments, or cellular-V2X deployments, the communication link 114 may be referred to as a sidelink (SL) . For example, a UE 104 may support wireless communication directly with another UE 104 over a PC5 interface.

A network entity 102 may support communications with the core network 106, or with another network entity 102, or both. For example, a network entity 102 may interface with the core network 106 through one or more backhaul links 116 (e.g., via an S1, N2, N3, or another network interface) . The network entities 102 may communicate with each other over the backhaul links 116 (e.g., via an X2, Xn, or another network interface) . In some implementations, the network entities 102 may communicate with each other directly (e.g., between the network entities 102) . In some other implementations, the network entities 102 may communicate with each other or indirectly (e.g., via the core network 106) . In some implementations, one or more network entities 102 may include subcomponents, such as an access network entity, which may be an example of an access node controller (ANC) . An ANC may communicate with the one or more UEs 104 through one or more other access network transmission entities, which may be referred to as a radio heads, smart radio heads, or transmission-reception points (TRPs) .

In some implementations, a network entity 102 may be configured in a disaggregated architecture, which may be configured to utilize a protocol stack physically or logically distributed among two or more network entities 102, 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 102 may include one or more of a central unit (CU) , a distributed unit (DU) , a radio unit (RU) , a RAN Intelligent Controller (RIC) (e.g., a Near-Real Time RIC (Near-RT RIC) , a Non-Real Time RIC (Non-RT RIC) ) , a Service Management and Orchestration (SMO) system, or any combination thereof.

An RU 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 102 in a disaggregated RAN architecture may be co-located, or one or more components of the network entities 102 may be located in distributed locations (e.g., separate physical locations) . In some implementations, one or more network entities 102 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) ) .

Split of functionality between a CU, a DU, and an RU may be flexible and may support different functionalities depending upon which functions (e.g., network layer functions, protocol layer functions, baseband functions, radio frequency functions, and any combinations thereof) are performed at a CU, a DU, or an RU. For example, a functional split of a protocol stack may be employed between a CU and a DU such that the CU may support one or more layers of the protocol stack and the DU may support one or more different layers of the protocol stack. In some implementations, the CU may host upper protocol layer (e.g., a layer 3 (L3) , a layer 2 (L2) ) functionality and signaling (e.g., Radio Resource Control (RRC) , service data adaption protocol (SDAP) , Packet Data Convergence Protocol (PDCP) ) . The CU may be connected to one or more DUs or RUs, and the one or more DUs or RUs may host lower protocol layers, such as a layer 1 (L1) (e.g., physical (PHY) layer) or an 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.

Additionally, or alternatively, a functional split of the protocol stack may be employed between a DU and an RU such that the DU may support one or more layers of the protocol stack and the RU may support one or more different layers of the protocol stack. The DU may support one or multiple different cells (e.g., via one or more RUs) . In some implementations, a functional split between a CU and a DU, or between a DU and an RU may be within a protocol layer (e.g., some functions for a protocol layer may be performed by one of a CU, a DU, or an RU, while other functions of the protocol layer are performed by a different one of the CU, the DU, or the RU) .

A CU may be functionally split further into CU control plane (CU-CP) and CU user plane (CU-UP) functions. A CU may be connected to one or more DUs via a midhaul communication link (e.g., F1, F1-C, F1-U) , and a DU may be connected to one or more RUs via a fronthaul communication link (e.g., open fronthaul (FH) interface) . In some implementations, a midhaul communication link or a fronthaul communication link may be implemented in accordance with an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities 102 that are in communication via such communication links.

The core network 106 may support user authentication, access authorization, tracking, connectivity, and other access, routing, or mobility functions. The core network 106 may be an evolved packet core (EPC) , or a 5G core (5GC) , which may include a control plane entity that manages access and mobility (e.g., a mobility management entity (MME) , an access and mobility management functions (AMF) ) and a 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) ) . In some implementations, the control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management (e.g., data bearers, signal bearers, etc. ) for the one or more UEs 104 served by the one or more network entities 102 associated with the core network 106.

The core network 106 may communicate with the packet data network 108 over one or more backhaul links 116 (e.g., via an S1, N2, N3, or another network interface) . The packet data network 108 may include an application server 118. In some implementations, one or more UEs 104 may communicate with the application server 118. A UE 104 may establish a session (e.g., a protocol data unit (PDU) session, or the like) with the core network 106 via a network entity 102. The core network 106 may route traffic (e.g., control information, data, and the like) between the UE 104 and the application server 118 using the established session (e.g., the established PDU session) . The PDU session may be an example of a logical connection between the UE 104 and the core network 106 (e.g., one or more network functions of the core network 106) .

In the wireless communications system 100, the network entities 102 and the UEs 104 may use resources of the wireless communications system 100 (e.g., time resources (e.g., symbols, slots, subframes, frames, or the like) or frequency resources (e.g., subcarriers, carriers) ) to perform various operations (e.g., wireless communications) . In some implementations, the network entities 102 and the UEs 104 may support different resource structures. For example, the network entities 102 and the UEs 104 may support different frame structures. In some implementations, such as in 4G, the network entities 102 and the UEs 104 may support a single frame structure. In some other implementations, such as in 5G and among other suitable radio access technologies, the network entities 102 and the UEs 104 may support various frame structures (i.e., multiple frame structures) . The network entities 102 and the UEs 104 may support various frame structures based on one or more numerologies.

One or more numerologies may be supported in the wireless communications system 100, and a numerology may include a subcarrier spacing and a cyclic prefix. A first numerology (e.g., μ=0) may be associated with a first subcarrier spacing (e.g., 15 kHz) and a normal cyclic prefix. In some implementations, the first numerology (e.g., μ=0) associated with the first subcarrier spacing (e.g., 15 kHz) may utilize one slot per subframe. A second numerology (e.g., μ=1) may be associated with a second subcarrier spacing (e.g., 30 kHz) and a normal cyclic prefix. A third numerology (e.g., μ=2) may be associated with a third subcarrier spacing (e.g., 60 kHz) and a normal cyclic prefix or an extended cyclic prefix. A fourth numerology (e.g., μ=3) may be associated with a fourth subcarrier spacing (e.g., 120 kHz) and a normal cyclic prefix. A fifth numerology (e.g., μ=4) may be associated with a fifth subcarrier spacing (e.g., 240 kHz) and a normal cyclic prefix.

A time interval of a resource (e.g., a communication resource) may be organized according to frames (also referred to as radio frames) . Each frame may have a duration, for example, a 10 millisecond (ms) duration. In some implementations, each frame may include multiple subframes. For example, each frame may include 10 subframes, and each subframe may have a duration, for example, a 1 ms duration. In some implementations, each frame may have the same duration. In some implementations, each subframe of a frame may have the same duration.

Additionally or alternatively, a time interval of a resource (e.g., a communication resource) may be organized according to slots. For example, a subframe may include a number (e.g., quantity) of slots. The number of slots in each subframe may also depend on the one or more numerologies supported in the wireless communications system 100. For instance, the first, second, third, fourth, and fifth numerologies (i.e., μ=0, μ=1, μ=2, μ=3, μ=4) associated with respective subcarrier spacings of 15 kHz, 30 kHz, 60 kHz, 120 kHz, and 240 kHz may utilize a single slot per subframe, two slots per subframe, four slots per subframe, eight slots per subframe, and 16 slots per subframe, respectively. Each slot may include a number (e.g., quantity) of symbols (e.g., OFDM symbols) . In some implementations, the number (e.g., quantity) of slots for a subframe may depend on a numerology. For a normal cyclic prefix, a slot may include 14 symbols. For an extended cyclic prefix (e.g., applicable for 60 kHz subcarrier spacing) , a slot may include 12 symbols. The relationship between the number of symbols per slot, the number of slots per subframe, and the number of slots per frame for a normal cyclic prefix and an extended cyclic prefix may depend on a numerology. It should be understood that reference to a first numerology (e.g., μ=0) associated with a first subcarrier spacing (e.g., 15 kHz) may be used interchangeably between subframes and slots.

In the wireless communications system 100, an electromagnetic (EM) spectrum may be split, based on frequency or wavelength, into various classes, frequency bands, frequency channels, etc. By way of example, the wireless communications system 100 may support one or multiple operating frequency bands, such as frequency range designations FR1 (410 MHz –7.125 GHz) , FR2 (24.25 GHz –52.6 GHz) , FR3 (7.125 GHz –24.25 GHz) , FR4 (52.6 GHz –114.25 GHz) , FR4a or FR4-1 (52.6 GHz –71 GHz) , and FR5 (114.25 GHz –300 GHz) . In some implementations, the network entities 102 and the UEs 104 may perform wireless communications over one or more of the operating frequency bands. In some implementations, FR1 may be used by the network entities 102 and the UEs 104, among other equipment or devices for cellular communications traffic (e.g., control information, data) . In some implementations, FR2 may be used by the network entities 102 and the UEs 104, among other equipment or devices for short-range, high data rate capabilities.

FR1 may be associated with one or multiple numerologies (e.g., at least three numerologies) . For example, FR1 may be associated with a first numerology (e.g., μ=0) , which includes 15 kHz subcarrier spacing; a second numerology (e.g., μ=1) , which includes 30 kHz subcarrier spacing; and a third numerology (e.g., μ=2) , which includes 60 kHz subcarrier spacing. FR2 may be associated with one or multiple numerologies (e.g., at least 2 numerologies) . For example, FR2 may be associated with a third numerology (e.g., μ=2) , which includes 60 kHz subcarrier spacing; and a fourth numerology (e.g., μ=3) , which includes 120 kHz subcarrier spacing.

In NR system, there may be a measurement gap configured, during which the UE can perform inter-frequency measurements for FR1 or FR2 and/or intra-frequency measurements for FR2. If a UE is configured with a measurement gap in RRC, all of measurement gaps are activated with a higher priority than data scheduling, that is, the UE is not expected to enable transmission/reception (Tx/Rx) of other signals/channels. For measurement gaps based on per-UE or per-FR measurement gap pattern, the measurement gap period can be 20, 40, 80, or 160 ms, and the measurement gap length can be 1.5, 3, 3.5, 4, 5.5, 6, 10, or 20 ms.

UE could be configured with a synchronization signal block (SSB) measurement timing configuration (SMTC) window, and the UE may do measurement in the window to assist cell selection and cell re-selection. In some cases, the configuration parameter may be:

For example, if the periodicityAndOffset configures that the periodicity is 5 and the offset is 4, and duration =sf1, then it means the measurement period is 5 subframes and a UE should do the measurement in the fourth subframe.

Extended reality (XR) is a broad term covering augmented reality (AR) , mixed reality (MR) and virtual reality (VR) . Along with cloud computing, XR applications typically require high throughput and low latency, and have a big packet size and variable data packet size. For an XR service, reliability and latency are important requirements. If data transmission in the measurement gap and SMTC window is not supported, then frequent measurement gaps would be needed, which will add latency to the XR traffic. For example, if the XR traffic which should be transmitted is in the measurement gap or SMTC window, it should be delayed to the next discontinuous reception (DRX) cycle. Therefore, it is necessary to improve XR capacity by relaxing scheduling restrictions based on network indication. For example, there are some discussions in release 19 to support transmission and reception in measurement gap for radio resource management (RRM) .

For solutions based on triggering/enabling by network signaling to enable Tx/Rx in gaps/restrictions that are caused by RRM measurements consider at least one of the following alternatives or combinations for further down-selection:

Alt. 1: Dynamic indication to enable Tx/Rx in particular gap (s) /restriction (s) that are caused by RRM measurements.

Alt. 2: Semi-persistent solution to deactivate/and/or re-activate one or more of gaps/restrictions that are caused by RRM measurements and to enable Tx/Rx during the deactivated in gaps/restrictions that are caused by RRM measurements.

Alt. 3: Semi-static solution to enable TX/RX in gaps/restrictions that are caused by RRM measurements.

Alt. 4: Dynamic solution to adapt/change gap/SMTC configuration to enable TX/RX in gaps/restrictions that are caused by RRM measurements.

Alt. 5: Rule-based solution to enable TX/RX in gaps/restrictions that are caused by RRM measurements.

In some cases, the network, e.g. a gNB, can indicate which channel could be transmitted or received in gaps/restrictions that are caused by RRM measurements. However, there may be multiple (e.g. two) channels overlapped in the measurement gap, details of which should be further studied.

Embodiments of the present disclosure provide a solution of communication. In the solution, a UE receives an indication from the BS, and the indication may indicate at least one channel that can be transmitted or received in the measurement gap. In addition, the UE can determine whether to transmit or receive a first channel or a second channel at least based on the indication, and priority information of the first and second channels, if the first and second channels are overlapped in a time period within the measurement gap. Therefore, a behavior associated with overlapped first and second channels in the measurement gap is defined and thus a communication to/from the UE may be guaranteed. Principles and implementations of the present disclosure will be described in detail below with reference to the figures.

In the present disclosure, the term “measurement gap” is used for the following embodiments, however the measurement gap can be interchangeably with one of the following: an SMTC window, a restriction gap, a gap/restriction caused by RRM measurements, or the like, the present disclosure does not limit for this aspect.

Reference is now made to FIG. 2, which illustrates a signalling chart illustrating communication process 200 in accordance with some example embodiments of the present disclosure. The process 200 may involve the BS 102 (i.e., an example of the network entity 102 in FIG. 1) and the UE 104 as shown in FIG. 1. It is to be understood that the process 200 may also be applied to another scenario different from that shown in FIG. 1, the present disclosure does not limit this aspect.

In the process 200, at 210, the BS 102 may transmit, and the UE 104 may receive, an indication which may indicate at least one channel that can be transmitted or received during a measurement gap.

In some implementations, the indication may be a dynamic indication or a semi-static indication. In some implementations, the indication may be transmitted via downlink control information (DCI) or a radio resource control (RRC) parameter. In some implementations, the indication may indicate at least one allowed transmission or reception in the measurement gap.

In some implementations, the indication may be implemented as at least one message per channel. In some examples, the indication may include first indication information indicating that a first channel can be transmitted/received during the measurement gap. For example, the first indication information may indicate that the first channel can be transmitted/received when it is overlapped with a measurement gap. In some examples, the indication may include second indication information indicating that a second channel can be transmitted/received during the measurement gap. For example, the second indication information may indicate that the second channel can be transmitted/received when it is overlapped with a measurement gap.

In the present disclosure, a first/second channel may also be referred to as a first/second signalling in some cases. The first and second channels (or signalling) are different at one or more of the following: a priority, carried information, a corresponding configuration index, a channel type, or a scheduling method.

In the present disclosure, a channel (such as the first channel and/or the second channel) may be indicated that it can be transmitted/received during the measurement gap, means that the channel can be transmitted/received if it is overlapped with the measurement gap. For example, part of or all the time resource of the channel may be overlapped with the measurement gap.

In some implementations, the first channel and the second channel may be overlapped in a time domain, and both the first channel and the second channel are overlapped with the measurement gap. The first channel and/or the second channel may be indicated to be transmitted/received during the measurement gap. In the process 200, at 220, the UE 104 may determine whether to transmit/receive the first or second channel based on priority information of the first and second channels and the indication.

In some implementations, the priority information of the first and second channels may include some or all of the following: a first priority of the first channel and a second priority of the second channel, first information carried in the first channel and second information carried in the second channel, a first configuration index corresponding to the first channel and a second configuration index corresponding to the second channel, channel types of the first and second channels, or scheduling methods for the first and second channels.

As a non-limiting example, the first priority may be the same as, be higher than, or be lower than the second priority. As a non-limiting example, the first information may have a higher priority level or a lower priority level than the second information. As a non-limiting example, the first configuration index may be smaller or larger than the second configuration index, which reflects the priority of the first and second channel. As a non-limiting example, a channel type of the first channel may be the same as or be different from that of the second channel, and different channel type corresponds to a different priority. As a non-limiting example, the scheduling method for the first channel may be the same as or be different from that for the second channel, and different scheduling method corresponds to a different priority. For instance, a channel type may be one of: PUCCH, PUSCH, PDCCH, PDSCH, etc, and the control channel PUCCH or PDCCH may have a higher priority than the data channel such as PUSCH or PDSCH. For instance, a scheduling type may be one of: a configured grant (CG) or a dynamic configured (DG) , and DG may have a higher priority than CG. For example, a PDSCH or a PUSCH may be scheduled by a DCI, in this case, a scheduling method of the PDSCH/PUSCH is DG.

In some example embodiments, at 220, the UE 104 may determine a standby channel based on the priority information of the first and second channels, and in addition determines whether to transmit the standby channel based on the indication.

In some examples, the collision or overlapping between the first and second channels can be handled by the UE 104, so as to determine the standby channel. In some examples, the indication may be considered so as to determine whether to transmit/receive the standby channel. For example, the standby channel may be the first channel, or the second channel, or a channel carrying information that is a multiplex of the first information and the second information.

If the standby channel is the first channel, then the first channel will be transmitted/received if the indication indicates that the first channel can be transmitted/received within the measurement gap.

If the standby channel is the second channel, then the second channel will be transmitted/received if the indication indicates that the second channel can be transmitted/received within the measurement gap.

If the standby channel is a new channel or one channel from the first channel and second channel, then the standby channel will be transmitted/received if the indication indicates that (1) any of the first or second channel can be transmitted/received within the measurement gap, or (2) the new channel can be transmitted/received within the measurement gap, or (3) both the first and second channels can be transmitted/received within the measurement gap.

In some instances, if the first priority of the first channel is higher than the second priority of the second channel, then the standby channel may be the first channel. In some instances, if the first priority of the first channel is higher than the second priority of the second channel and configuration information does not indicate a multiplexing manner for the first and second channels, then the standby channel may be the first channel.

In some instances, if the first priority is the same as the second priority, and the first information has a higher priority level than the second information, then the standby channel may be the first channel. For example, the first channel may be a PUCCH carrying HARQ-ACK, and the second channel may be another PUCCH carrying CSI.

In some instances, if the first channel is PUSCH and the second channel is PUCCH, then the standby channel may be the first channel, i.e. PUSCH. For example, the first priority and the second priority may be the same. For another example, the first priority and the second priority may be different, and configuration information indicates a multiplexing manner for the first and second channels. For example, the second information carried in the PUCCH may be multiplexed into the PUSCH, to determine the standby channel.

In some instances, if a first configuration index corresponding to the first channel is smaller than a second configuration index corresponding to the second channel, and both the first and the second channels are SPS PDSCHs, then the standby channel may be the first channel.

In some instances, if the first channel is a PUSCH scheduled by a DCI and the second channel is a CG PUSCH, and a time duration from an end symbol of the DCI to a starting symbol of the CG PUSCH is larger than a first threshold, then the standby channel may be the first channel.

In some instances, if the first channel is a PDSCH scheduled by a DCI and the second channel is a SPS PDSCH, and a time duration from an end symbol of the DCI to a starting symbol of the SPS PDSCH is larger than a second threshold, then the standby channel may be the first channel.

Some detailed embodiments are provided below for better understanding the solution of the present disclosure.

In some embodiments, the UE 104 would not multiplex different UCI types in a PUCCH transmission with repetitions over slots. If a UE 104 would transmit a first PUCCH over more than one slot and a second PUCCH over one or more slots, and the transmissions of the first PUCCH and the second PUCCH would overlap in a number of slots, then the following priority levels should be considered: for each slot of the number of slots and with UCI type priority of HARQ-ACK > SR > CSI with higher priority > CSI with lower priority.

In some examples, refer to FIG. 3A which illustrates an example schematic of overlapped transmissions 310. If the first channel is PUCCH 1 carrying a higher priority UCI type (e.g. HARQ-ACK) and the second channel is PUCCH 2 carrying a lower priority UCI type (e.g. CSI) , and the first channel and the second channel with a same priority are overlapped in time domain within the measurement gap, then the first channel may be selected, e.g. determined as a standby channel. In addition, an indication associated with the first channel may be considered. For example, if the indication 1 indicates that the first channel (PUCCH 1 carrying HARQ-ACK) can be transmitted during the measurement gap, then the UE 104 may transmit the first channel (PUCCH 1 carrying HARQ-ACK) .

It is understood that if there is no indication 1 associated with the first channel, then the first channel will not be transmitted, in this case, either the first channel or the second channel will be transmitted.

It is understood that the second channel (PUCCH 2 carrying CSI) will not be transmitted, no matter whether there is an indication 2, for example, the indication 2 may indicate that the second channel can be transmitted in the measurement gap.

In some embodiments, the UE 104 is not expected to be scheduled by a PDCCH ending in symbol i to transmit a PUSCH on a given serving cell overlapping in time with a transmission occasion, where the UE is allowed to transmit a PUSCH with configured grant (CG-PUSCH) , starting in a symbol j on the same serving cell if the end of symbol i is not at least N₂ symbols before the beginning of symbol j. The value N₂ in symbols is determined according to the UE processing capability.

In some examples, if the first channel is a CG PUSCH and the second channel is a DG PUSCH, and the first channel and the second channel with a same priority are overlapped in time domain within the measurement gap. In some examples, a time duration from an end symbol of a DCI which schedules the second channel to a starting symbol of the first channel may be considered.

For example, if the time duration exceeds N₂ symbols, then the second channel (the DG PUSCH) is selected. If an indication associated with the second channel indicates that the second channel can be transmitted in the measurement gap, then the UE 104 may further transmit the second channel (the DG PUSCH) . Otherwise, if the indication associated with the second channel indicates that the second channel cannot be transmitted in the measurement gap or the indication is absent, then the UE 104 may not transmit the second channel (the DG PUSCH) , e.g. either the first channel or the second channel will be transmitted.

For another example, if the time duration is less than N₂ symbols, then the first channel (the CG PUSCH) is selected. If an indication associated with the first channel indicates that the first channel can be transmitted in the measurement gap, then the UE 104 may further transmit the first channel (the CG PUSCH) . Otherwise, if the indication associated with the first channel indicates that the first channel cannot be transmitted in the measurement gap or the indication is absent, then the UE 104 may not transmit the first channel (the CG PUSCH) , e.g. either the first channel or the second channel will be transmitted.

In some embodiments, if two SPS PDSCHs would be overlapped with each other, then the SPS with larger configuration index would be dropped, only the SPS PDSCH with smaller configuration index would be transmitted.

In some examples, refer to FIG. 3B which illustrates an example schematic of overlapped transmissions 320. If the first channel is SPS PDSCH 1 corresponding to a smaller configuration index and the second channel is SPS PDSCH 2 corresponding to a bigger configuration index, and the first channel and the second channel with a same priority are overlapped in time domain within the measurement gap, then the first channel may be selected and the second channel will be dropped. In addition, an indication associated with the first channel may be considered. For example, if the indication indicates that the SPS PDSCH can be transmitted in the measurement gap, then the UE 104 may receive the first channel (SPS PDSCH 1 corresponding to a smaller configuration index) .

It is understood that if the indication is absent, the UE 104 may determine that the SPS PDSCH cannot be transmitted in the measurement gap, in this case, the first channel will not be received by the UE 104.

In some embodiments, if a PDSCH scheduled by a DCI would be overlapped with a SPS PDSCH, and the DCI ends at least a predefined number (e.g. 14 ) of symbols before the earliest starting symbol of the PDSCH (s) without the corresponding PDCCH transmission, the SPS PDSCH would be dropped, only the PDSCH scheduled by the DCI could be transmitted.

In some examples, if the first channel is a PDSCH without a corresponding DCI (e.g. SPS PDSCH) and the second channel is a PDSCH scheduled by a DCI, and the first channel and the second channel with a same priority are overlapped in time domain within the measurement gap. In some examples, a time duration from an end symbol of a DCI which schedules the second channel to a starting symbol of the first channel may be considered.

For example, if the time duration exceeds a predefined number, then the second channel (the PDSCH scheduled by the DCI) is selected. If an indication indicates that the second channel can be transmitted in the measurement gap, then the UE 104 may determine to receive the second channel (the PDSCH scheduled by the DCI) . Otherwise, if the indication indicates that the second channel cannot be transmitted in the measurement gap or the indication is absent, then the UE 104 may not receive the second channel (the PDSCH scheduled by the DCI) , e.g. either the first channel or the second channel will be received.

For another example, if the time duration is less than the predefined number, then the first channel (the PDSCH without a corresponding DCI) is selected. If an indication indicates that the first channel can be transmitted in the measurement gap, then the UE 104 may determine to receive the first channel (the PDSCH without a corresponding DCI) . Otherwise, if the indication indicates that the first channel cannot be transmitted in the measurement gap or the indication is absent, then the UE 104 may not receive the first channel (the PDSCH without a corresponding DCI) , e.g. either the first channel or the second channel will be transmitted.

In some embodiments, if a transmission of a PUCCH would overlap with a transmission of PUSCH, and the timeline is met, the UCI on the PUCCH could be multiplexed on the PUSCH.

In some examples, refer to FIG. 3C which illustrates an example schematic of overlapped transmissions 330. If the first channel is PUSCH and the second channel is PUCCH, the PUSCH and the PUCCH have a same priority, and the first channel and the second channel are overlapped in time domain within the measurement gap, then the UCI on the second channel will be multiplexed on the first channel. In addition, an indication associated with the first channel may be considered. For example, if the indication indicates that the PUSCH can be transmitted in the measurement gap, then the UE 104 may transmit the first channel (PDSCH with multiplexed UCI) .

It is understood that if the indication is absent, the UE 104 may determine not to transmit the first channel in the measurement gap.

In some embodiments, the first channel may be a PUCCH with a higher priority and the second channel may be another PUCCH with a lower priority, and the first channel and the second channel are overlapped in time domain within the measurement gap.

In some examples, refer to FIG. 3D which illustrates an example schematic of overlapped transmissions 340. In some examples, if UCI-MuxWithDifferentPriority is provided, then UCI in the first channel and UCI in the second channel can be multiplexed in a new PUCCH. As shown in FIG. 3D, a PUCCH 3 may be determined by multiplexing UCI in PUCCH 1 and UCI in PUCCH 2. For example, resources of the PUCCH 3 may be determined based on the UCI in PUCCH 1 and the UCI in PUCCH 2.

In addition, an indication 1 associated with PUCCH 1 and/or an indication 2 associated with PUCCH 2 may be further considered. The indication 1 may indicate that PUCCH 1 can be transmitted in the measurement gap, and the indication 2 may indicate that PUCCH 2 can be transmitted in the measurement gap.

For example, if the indication 1 indicates that PUCCH 1 can be transmitted in the measurement gap and/or the indication 2 may indicate that PUCCH 2 can be transmitted in the measurement gap, then the UE 104 may determine to transmit the PUCCH 3. For instance, if any one of PUCCH 1 or PUCCH 2 is indicated to be transmitted in the measurement gap, then the UE 104 may determine to transmit the PUCCH 3.

For example, if both the indication 1 and the indication 2 are absent, then the UE 104 may determine not to transmit the PUCCH 3. For instance, if none of PUCCH 1 or PUCCH 2 is indicated to be transmitted in the measurement gap, then the UE 104 may determine not to transmit the PUCCH 3.

In some other examples, if UCI-MuxWithDifferentPriority is not provided, then the first channel which is a PUCCH with a higher priority can be transmitted, if the indication 1 indicates that the PUCCH 1 can be transmitted in the measurement gap. In some other examples, if UCI-MuxWithDifferentPriority is not provided, then none of the first channel or the second channel will be transmitted, if the indication 1 indicates that the PUCCH 1 cannot be transmitted in the measurement gap or if the indication 1 is absent.

In some embodiments, the first channel may be a PUCCH with a higher priority and the second channel may be a PUSCH with a lower priority, and the first channel and the second channel are overlapped in time domain within the measurement gap.

In some examples, if UCI-MuxWithDifferentPriority is provided, then UCI in the first channel can be multiplexed into the second channel (i.e. PUSCH) . In addition, an indication 1 associated with the first channel and/or an indication 2 associated with the second channel may be further considered. The indication 1 may indicate that the first channel can be transmitted in the measurement gap, and the indication 2 may indicate that the second channel can be transmitted in the measurement gap.

For example, if the indication 1 indicates that the first channel can be transmitted in the measurement gap and/or the indication 2 may indicate that the second channel can be transmitted in the measurement gap, then the UE 104 may determine to transmit the second channel with multiplexed UCI. For instance, if any one of the first channel or the second channel is indicated to be transmitted in the measurement gap, then the UE 104 may determine to transmit the second channel with multiplexed UCI.

For example, if both the indication 1 and the indication 2 are absent, then the UE 104 may determine not to transmit the second channel. For instance, if none of the first channel or the second channel is indicated to be transmitted in the measurement gap, then the UE 104 may determine not to transmit the second channel.

In some other examples, if UCI-MuxWithDifferentPriority is not provided, then the first channel which is a PUCCH with a higher priority can be transmitted, if the indication 1 indicates that the PUCCH can be transmitted in the measurement gap. In some other examples, if UCI-MuxWithDifferentPriority is not provided, then none of the first channel or the second channel will be transmitted, if the indication 1 indicates that the PUCCH cannot be transmitted in the measurement gap or if the indication 1 is absent.

It should be noted that the examples with reference to FIGS. 3A-3D are provided only for illustration without any limitations, for example, although the first and second channels are shown within the measurement gap, the present disclosure may also include examples that only part of the first/second channel is overlapped with the measurement gap.

As such, the UE 104 may handle the channel collision according to priority information firstly, and then determines whether to transmit/receive according to the indication.

In some example embodiments, at 220, the UE 104 may determine whether the first channel or the second channel can be transmitted or received during the measurement gap based on the indication.

In some examples, if none of the first or second channel can be transmitted/received during the measurement gap, then the UE 104 may determine not to transmit/receive the first or second channel, that is, no channel will be transmitted/received.

In some examples, if the first channel can be transmitted/received during the measurement gap and the second channel cannot be transmitted/received during the measurement gap, then the UE 104 can determine to transmit/receive the first channel.

In some examples, if the second channel can be transmitted/received during the measurement gap and the first channel cannot be transmitted/received during the measurement gap, then the UE 104 can determine to transmit/receive the second channel.

In some examples, if both the first and second channels can be transmitted/received during the measurement gap, then the UE 104 may further determine whether to transmit or receive the first or second channel based on a first overlap size between the first channel and the measurement gap and a second overlap size between the second channel and the measurement gap. For example, if the first overlap size is smaller than the second overlap size, the UE 104 may determine to transmit or receive the first channel. For example, if the first overlap size is smaller than a size threshold (e.g., pre-configured by the BS 102) , the UE 104 may determine to transmit or receive the first channel. For another example, if the first overlap size equals to the second overlap size, then the UE 104 may further determine whether to transmit/receive a standby channel based on the priority information of a first and second channels.

In some other examples, if both the first and second channels can be transmitted/received during the measurement gap, then the UE 104 may further determine whether to transmit/receive a standby channel based on the priority information of a first and second channels.

For example, the standby channel may be the first channel, or the second channel, or a new channel carrying information that is a multiplex of the first information and the second information.

In some instances, if the first channel is a PUSCH scheduled by a DCI and the second channel is a CG PUSCH, and a time duration from an end symbol of the DCI to a starting symbol of the CG PUSCH is larger than a first threshold, then the standby channel may be the first channel. Otherwise, the standby channel will be the second channel.

In some instances, if the first channel is a PDSCH scheduled by a DCI and the second channel is a SPS PDSCH, and a time duration from an end symbol of the DCI to a starting symbol of the SPS PDSCH is larger than a second threshold, then the standby channel may be the first channel. Otherwise, the standby channel will be the second channel.

It is to be noted that the determination of the standby channel is similar with that discussed above, and thus will not be repeated herein.

As such, the UE 104 may consider the indication firstly, and then handles the channel collision according to the priority information.

In some implementations, the UE 104 may transmit, and the BS 102 may receive, assistant information, and the assistant information may indicate to the BS 102 to enable Tx/Rx in gaps/restrictions that are caused by RRM measurements.

The assistant information could include one or more of the following: assistant information related to measurement occasions, assistance information related to channel conditions, assistance information related to traffic, or assistance information related to UE mobility.

In some implementations, the BS 102 may transmit, and the UE 104 may receive, the indication which is used to enable Tx/Rx in gaps/restrictions that are caused by RRM measurements after predefined number of time units of the time unit when the UE 104 sent the assistant information. For example, the BS 102 may transmit the indication after the predefined number of time units from a time when the assistant information is received. For example, the indication may indicate that at least one channel can be transmitted or received if the at least one channel is overlapped with a measurement gap. The predefined number could be configured by the BS 102 or predefined in the 3GPP specification. The time unit could be any of: slot, or symbol, or subframe.

In some instances, the indication is received in a time window. And the length of the time window could be configured by the BS 102, e.g. via RRC signaling. For example, the BS 102 may send the indication in a time window also.

Using this method, the UE 104 could receive the indication if necessary, which would decrease the complexity of the UE’s implement, and has benefit on UE’s power saving.

In the process 200, the BS 102 may determine whether to transmit/receive the first or second channel at 225. The operation at 225 by the BS 102 is similar with that at 220 by the UE 104, for example, the UE 104 may determine to transmit/receive a standby channel, and the BS 102 may determine to receive/transmit the standby channel. In this way, a consistence between the UE 104 and the BS 102 can be guaranteed.

In addition or alternatively, the BS 102 and the UE 104 may perform a communication at 230. In some examples, the UE 104 transmits (or receives) a standby channel, and the BS 102 receives (or transmits) the standby channel.

According to some embodiments discussed with reference to FIGS. 2-3D, priority information and/or an indication may be used by the BS 102 or the UE 104, to determine whether to transmit/receive a first or a second channel. As such, a channel collision in a measurement gap may be handled, and the communication can be guaranteed. In some cases, a standby channel may be transmitted/received during the measurement gap, and thus related services can be guaranteed with reduced latency.

It is to be understood that the embodiments with reference to FIG. 2 are only for illustration without any limitation, for example, some step (s) may be omitted, reordered, modified, or combined, some further step (s) may be also included, the present disclosure does not limit for this aspect. It is understood that some additional embodiments based on FIG. 2 are still in the protection scope of the present disclosure.

In some implementations, the indication may be omitted or not be considered. In some examples, the first channel and the second channel may be overlapped in a time domain, and both the first channel and the second channel are overlapped with the measurement gap. In some examples, the BS 102 and/or the UE 104 may determine whether to transmit or receive the first or second channel based on a first overlap size between the first channel and the measurement gap and a second overlap size between the second channel and the measurement gap. For example, if the first overlap size is smaller than the second overlap size, the BS 102 and/or the UE 104 may determine to transmit or receive the first channel. For example, if the first overlap size is smaller than a size threshold (e.g., pre-configured by the BS 102) , the BS 102 and/or the UE 104 may determine to transmit or receive the first channel. For example, if the second overlap size is larger than a size threshold (e.g., pre-configured by the BS 102) , the BS 102 and/or the UE 104 may determine to drop the second channel. For another example, if the first overlap size equals to the second overlap size, then the UE 104 may further determine whether to transmit/receive a standby channel based on the priority information of a first and second channels, for instance, details of the standby channel may refer to embodiments above.

It shall be understood that although the terms “first” and “second” or the like may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. For example, a first channel could also be termed as a second channel, and similarly, a second channel could also be termed as a first channel, without departing from the scope of embodiments.

It shall be understood that although a channel collision between a first channel and a second channel is discussed in some embodiments above, more channels can be considered without limiting. For example, there may be channel 1, channel 2, and channel 3 overlapped with each other, and each of channel 1, channel 2, and channel 3 is overlapped with the measurement gap. In some instances, channel 1 and channel 2 may be regarded as the first channel and the second channel respectively, and a candidate standby channel can be determined; in addition, the candidate standby channel and channel 3 may be regarded as the first channel and the second channel respectively, and a standby channel can be determined.
