DETAILED DESCRIPTION

In some wireless communication systems, user equipments (UEs) may communicate with network entities via one or more component carriers. For example, a UE may support carrier aggregation and may signal a UE supported channel bandwidth via a bandwidth combination set (BCS) . Further, the UE may signal a set of features that the UE may be capable of supporting per component carrier. For example, the UE may signal a supported downlink bandwidth capability per component carrier. However, in some cases, a UE may be unable to support all the possible bandwidth configurations of a BCS due to radio frequency or baseband limitations in the hardware or software of the UE. As such, in some examples, a UE may indicate multiple capability messages to indicate the supported bandwidths. Such signaling may result in a relatively large increase in signaling overhead thus causing an increase in delay and a decrease in efficiency and reliability within a wireless communication system.

Therefore, to reduce the signaling overhead, in accordance with the aspects of the present disclosure, a UE may transmit an aggregated capability message to indicate a total processing capability of the UE for a set of component carriers. For example, if the UE supports carrier aggregation, dual connectivity modes, or both the UE may transmit an aggregated capability message for the UE to indicate the capability of the UE over one or more component carriers of the set of component carriers rather than per component carrier. In some cases, the aggregated capability message may indicate a baseband capability of the UE that is based on one or more transmission parameters. In some other cases, the aggregated capability message may indicate a radio frequency processing capability based on the maximum channel bandwidth for each subcarrier spacing (SCS) for the set of component carriers. Further, the UE may indicate the same capability message or different capability message for time domain duplexing (TDD) and frequency domain duplexing (FDD) bands as the maximum number of uplink or downlink layers may be different for TDD and FDD bands. In addition, the UE may be capable of flexibly indicating the baseband processing capability and the radio frequency processing capability for TDD and FDD bands. Moreover, the UE may implement the techniques of the present disclosure for intra-band carrier aggregation, inter-band carrier aggregation, and dual connectivity modes. Therefore, the UE may transmit the aggregated capability message to enable the network entity to schedule resources for future communications over each of the one or more component carriers.

Aspects of the disclosure are initially described in the context of wireless communications systems. Additional aspects of the disclosure are described with reference to a wireless communications system 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 aggregated capability signaling for carrier aggregation and dual connectivity modes.

FIG. 1 shows an example of a wireless communications system 100 that supports aggregated capability signaling for carrier aggregation and dual connectivity modes in accordance with one or more aspects of the present disclosure. The wireless communications system 100 may include one or more devices, such as one or more network devices (e.g., 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 communication link (s) 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 the communication link (s) 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 in the wireless communications system 100 (e.g., other wireless communication devices, including 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 a core network 130, or with one another, or both. For example, network entities 105 may communicate with the core network 130 via backhaul communication link (s) 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 backhaul communication link (s) 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 the 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 link (s) 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) or 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 or network equipment 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 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 one network entity (e.g., a network entity 105 or 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 multiple network entities (e.g., network entities 105) , such as an integrated access and 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) , such as a CU 160, a distributed unit (DU) , such as a DU 165, a radio unit (RU) , such as an RU 170, a RAN Intelligent Controller (RIC) , such as an 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) system, such as an SMO system 180, 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 of the 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, or 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 (e.g., one or more CUs) may be connected to a DU 165 (e.g., one or more DUs) or an RU 170 (e.g., one or more RUs) , or some combination thereof, and the DUs 165, RUs 170, or both 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 multiple different RUs, such as an RU 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 a DU 165 via a midhaul communication link 162 (e.g., F1, F1-c, F1-u) , and a DU 165 may be connected to an RU 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 (e.g., one or more of the network entities 105) that are in communication via such communication links.

In some wireless communications systems (e.g., the 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 of the network entities 105 (e.g., network entities 105 or IAB node (s) 104) may be partially controlled by each other. The IAB node (s) 104 may be referred to as a donor entity or an IAB donor. A DU 165 or an RU 170 may be partially controlled by a CU 160 associated with a network entity 105 or base station 140 (such as a donor network entity or a donor base station) . The one or more donor entities (e.g., IAB donors) may be in communication with one or more additional devices (e.g., IAB node (s) 104) via supported access and backhaul links (e.g., backhaul communication link (s) 120) . IAB node (s) 104 may include an IAB mobile termination (IAB-MT) controlled (e.g., scheduled) by one or more DUs (e.g., DUs 165) of a coupled IAB donor. An IAB-MT may be equipped with 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 IAB node (s) 104 used for access via the DU 165 of the IAB node (s) 104 (e.g., referred to as virtual IAB-MT (vIAB-MT) ) . In some examples, the IAB node (s) 104 may include one or more DUs (e.g., DUs 165) that support communication links with additional entities (e.g., IAB node (s) 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., the IAB node (s) 104 or components of the IAB node (s) 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 node (s) 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 the core network 130. The IAB donor may include one or more of a CU 160, a DU 165, and an RU 170, in which case the CU 160 may communicate with the core network 130 via an interface (e.g., a backhaul link) . The IAB donor and IAB node (s) 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 130 via an interface, which may be an example of a portion of a backhaul link, and may communicate with other CUs (e.g., including a CU 160 associated with an alternative IAB donor) via an Xn-C interface, which may be an example of another portion of a backhaul link.

IAB node (s) 104 may refer to RAN nodes that provide 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 (s) 104, and the IAB-MT may act as a scheduled node towards parent nodes associated with IAB node (s) 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 other IAB node (s) 104) . Additionally, or alternatively, IAB node (s) 104 may also be referred to as parent nodes or child nodes to other IAB node (s) 104, depending on the relay chain or configuration of the AN. The IAB-MT entity of IAB node (s) 104 may provide a Uu interface for a child IAB node (e.g., the IAB node (s) 104) to receive signaling from a parent IAB node (e.g., the IAB node (s) 104) , and a DU interface (e.g., a DU 165) may provide a Uu interface for a parent IAB node to signal to a child IAB node or UE 115.

For example, IAB node (s) 104 may be referred to as parent nodes that support communications for child IAB nodes, or may be referred to as child IAB nodes associated with IAB donors, or both. An IAB donor may include a CU 160 with a wired or wireless connection (e.g., backhaul communication link (s) 120) to the core network 130 and may act as a parent node to IAB node (s) 104. For example, the DU 165 of an IAB donor may relay transmissions to UEs 115 through IAB node (s) 104, or may directly signal transmissions to a UE 115, or both. The CU 160 of the IAB donor may signal communication link establishment via an F1 interface to IAB node (s) 104, and the IAB node (s) 104 may schedule transmissions (e.g., transmissions to the UEs 115 relayed from the IAB donor) through one or more DUs (e.g., DUs 165) . That is, data may be relayed to and from IAB node (s) 104 via signaling via an NR Uu interface to MT of IAB node (s) 104 (e.g., other IAB node (s) ) . Communications with IAB node (s) 104 may be scheduled by a DU 165 of the IAB donor or of IAB node (s) 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 test 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., components such as an IAB node, a DU 165, a CU 160, an RU 170, an RIC 175, an SMO system 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, vehicles, or meters, among other examples.

The UEs 115 described herein may be able to communicate with various types of devices, such as UEs 115 that may sometimes operate 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 the communication link (s) 125 (e.g., one or more access links) using resources associated with one or more carriers. The term “carrier” may refer to a set of RF spectrum resources having a defined PHY layer structure for supporting the communication link (s) 125. For example, a carrier used for the communication link (s) 125 may include a portion of an RF spectrum band (e.g., a bandwidth part (BWP) ) that is operated according to one or more PHY layer channels for a given RAT (e.g., LTE, LTE-A, LTE-A Pro, NR) . Each PHY 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, such as one or more of the network entities 105) .

In some examples, such as in a carrier aggregation configuration, a carrier may 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 RAT) .

The communication link (s) 125 of 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 RAT (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 SCS 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 SCS (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 T_s=1/ (Δf_max·N_f) seconds, for which Δf_max may represent a supported SCS, and N_f 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 SCS. 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, such as the wireless communications system 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., N_f) sampling periods. The duration of a symbol period may depend on the SCS 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 UEs 115 (e.g., one or more UEs) or may include UE-specific search space sets for sending control information to a UE 115 (e.g., a specific UE) .

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) ) . 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 network entity 105 operating with lower power (e.g., a base station 140 operating with lower power) relative to 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 more 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, such as the coverage area 110. In some examples, coverage areas 110 (e.g., different coverage areas) associated with different technologies may overlap, but the coverage areas 110 (e.g., different coverage areas) may be supported by the same network entity (e.g., a network entity 105) . In some other examples, overlapping coverage areas, such as a coverage area 110, associated with different technologies may be supported by different network entities (e.g., the network entities 105) . The wireless communications system 100 may include, for example, a heterogeneous network in which different types of the network entities 105 support communications for coverage areas 110 (e.g., different coverage areas) using the same or different RATs.

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 may 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 (e.g., one or more of the UEs 115) via a device-to-device (D2D) communication link, such as a 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 one or more of the 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 one hundred 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) RAT, 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 a transmitting device (e.g., a network entity 105 or a UE 115) along a single beam direction (e.g., a direction associated with the receiving device, such as another network entity 105 or 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., the communication link (s) 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 relatively 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 of the wireless communications system 100, UEs 115 may communicate with network entities 105 via one or more component carriers. For example, a UE 115 may support carrier aggregation and may signal a UE 115 supported channel bandwidth via a BCS. Further, the UE 115 may signal a set of features that the UE 115 may be capable of supporting per component carrier. For example, the UE 115 may signal a supported downlink bandwidth capability per component carrier. However, in some cases, a UE 115 may be unable to support all the possible bandwidth configurations of a BCS due to radio frequency or baseband limitations. As such, in some examples, a UE 115 may indicate multiple capability messages to indicate the supported bandwidths. Such signaling may result in a relatively large increase in signaling overhead thus causing an increase in delay and a decrease in efficiency and reliability within the wireless communications system 100.

Therefore, to reduce the signaling overhead, in accordance with the aspects of the present disclosure, a UE 115 may transmit an aggregated capability message to indicate a total processing capability of the UE 115 for a set of component carriers. For example, if the UE 115 supports carrier aggregation, dual connectivity modes, or both the UE 115 may transmit an aggregated capability message for the UE 115 to indicate the capability of the UE 115 with respect to multiple component carriers of the set of component carriers rather than per component carrier. In some cases, the aggregated capability message may indicate a baseband capability of the UE 115 that is based on one or more transmission parameters. In some other cases, the aggregated capability message may indicate a radio frequency processing capability based on the maximum channel bandwidth for each SCS for the set of component carriers. Further, the UE 115 may indicate the same capability message or different capability message for TDD and FDD bands as the maximum number of uplink or downlink layers may be different for TDD and FDD bands. In addition, the UE 115 may be capable of flexibly indicating the baseband processing capability and the radio frequency processing capability for TDD and FDD bands. Moreover, the UE 115 may implement the techniques of the present disclosure for intra-band carrier aggregation, inter-band carrier aggregation, and dual connectivity modes. Therefore, the UE 115 may transmit the aggregated capability message to enable the network entity 105 to schedule resources for future communications over each of the one or more component carriers.

FIG. 2 shows an example of a wireless communications system 200 that supports aggregated capability signaling for carrier aggregation and dual connectivity modes 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 support carrier aggregation and communicate with the network entity 105-a via a set of component carriers. In some other examples, the UE 115-a may support dual connectivity modes to communicate with the network entity 105-a over two connections (e.g., an LTE and an NR connection) . When supporting carrier aggregation, the UE 115-a may transmit one or more capability messages to indicate a downlink feature set per component carrier (e.g., FeatureSetDownlinkPerCC) to indicate one or more transmission parameters for the respective component carriers of a set of component carriers. For example, the one or more transmission parameters may indicate a supported SCS per component carrier (e.g., supportedSubcarrierSpacingDL) , a maximum channel bandwidth per component carrier (e.g., supportedBandwidthDL) , a maximum quantity of MIMO layers per component carrier (e.g., maxNumberMIMO-LayersPDSCH) , a maximum modulation order supported per component carrier (e.g., supportedModulationOrderDL) , or any combination thereof.

Further, for carrier aggregation, the UE 115-a may signal a channel bandwidth supported by the UE 115-a via a BCS. A BCS may be representative of a set of multiple channel bandwidths that the UE 115-a is capable of supporting. For example, to reduce signaling overhead, the UE 115-a may indicate to the network entity 105-a that the UE 115-a can support any channel bandwidth within in BCS. Further, for carrier aggregation, the maximum channel bandwidth indicated per component carrier via a capability message may limit the channel bandwidth supported by a UE 115-a. However, in some examples, the UE 115-a may be unable to support one or more bandwidth configurations of a BCS due to one or more radio frequency or baseband limitations. Therefore, in some examples, the UE 115-a may indicate multiple supported combinations of feature sets in a feature set combination to cover each possible channel bandwidth aggregation that is below the maximum limit of channel bandwidth supported by the UE 115-a. While such signaling may be relatively simple, there may be an increase in signaling overhead. For example, to indicate the multiple supported bandwidth combinations of feature sets, the UE 115-a may transmit multiple capability messages (e.g., a capability message per component carrier) resulting in an increase in signaling overhead. Further, due to an increase in signaling, the network entity 105-amay refrain from determining scheduling information for the UE 115-a until the network entity 105-a receives each capability message, thus resulting in the increase in latency within the wireless communications system 200.

Thus, in accordance with the techniques of the present disclosure, to reduce the signaling overhead and latency within the wireless communications system 200, the UE 115-a may transmit an aggregated capability message 215 to indicate a total processing capability 220 of the UE 115-a for a set of component carriers. Further, the UE 115-a may transmit the aggregated capability message 215 to indicate the capability of the UE 115-a for communications between the UE 115-a and the network entity. Thus, based on the UE 115-a supporting carrier aggregation, the UE 115-a may transmit the aggregated capability message 215 to indicate the total processing capability 220 of the UE 115-a over the set of component carriers used for the communications between the UE 115-a and the network entity 105-a. Additionally, or alternatively, the UE 115-a may use a dual connectivity mode and the UE 115-a can transmit the aggregated capability message 215 to indicate an aggregate of capabilities both connections associated with the dual connectivity mode (e.g., both an LTE connection and a 5G NR connection) .

In some examples, the total processing capability 220 indicated via the aggregated capability message may be a total baseband processing capability 225 for the UE 115-a. Moreover, the total baseband processing capability 225 of the UE 115-a for the set of component carriers may be based on one or more transmission parameters. The one or more transmission parameters may include a maximum channel bandwidth for each respective component carrier of the set of component carriers (e.g., BWi is the maximum channel bandwidth for the ith component carrier) The one or more transmission parameters may also include an SCS for each respective component carrier of the set of component carriers (e.g., μi is the numerology for the ith component carrier, where 0, 1, and 2 correspond to 15 kHz, 30 kHz, and 60 kHz respectively for frequency range 1 (FR1) ) . Further, the one or more transmission parameters may include a maximum quantity of MIMO layers (e.g., downlink or uplink MIMO layers) for each respective component carrier of the set of component carriers (e.g., is the maximum quantity of MIMO layers for the ith component carrier) . Moreover, the one or more transmission parameters may also include a function, Y (·) , that represents a relation between different modulation orders for each of component carrier (e.g., Y (QPSK) =2, Y (16QAM) =4, Y (64QAM) =8, Y (1024QAM) =10) . Therefore, the UE 115-a may calculate the total baseband processing capability 225 using the one or more transmission parameters in accordance with Equation 1 shown below. For example, the UE 115-a may calculate total baseband processing capability 225 by calculating the sum of the total baseband processing capability 225 for each respective component carrier.

In some cases, the UE 115-a may refrain from including one or more transmission parameters when calculating the total baseband processing capability 225 to reduce the signaling design complexity of the aggregated capability message 215. For example, the maximum quantity of MIMO layers and the maximum modulation orders for each respective component carrier of the set of components may be equal or the same with the same band combination (e.g., within the same BCS) . Therefore, the UE 115-a may use Equation 2 below to calculate the total baseband processing capability 225 via the aggregated capability message 215 and refrain from considering the maximum quantity of MIMO layers and the maximum modulation orders for each respective component carrier of the set of components. Further, the total baseband processing capability 225 may be based on a maximum channel bandwidth for each respective SCS of a set of SCSs that the UE 115-a is capable of supporting over the set of component carriers.

In some other examples, the total processing capability 220 indicated via the aggregated capability message 215 may be a total radio frequency processing capability 230 for the UE 115-a. Further, the total radio frequency processing capability 230 may be based on a maximum radio frequency bandwidth for each respective SCS of the set of SCSs that the UE 115-a is capable of supporting over the set of component carriers. Therefore, the UE 115-a may calculate the total radio frequency processing capability 230 in accordance with Equation 3 below.

Further, in some cases, the total processing capability 220 may include a first capability and a second capability. The first capability may be applicable to one or more frequency bands associated with TDD and the second capability may be applicable to one or more frequency bands associated with FDD. That is, the UE 115-a transmitting the aggregated capability message 215 may include the UE 115-a transmitting a first aggregated capability message for frequency bands associated with TDD and a second aggregated capability message for frequency bands associated with FDD. For example, for indicating the total baseband processing capability 225 of the UE 115-a, the UE 115-a may calculate the total baseband processing capability 225 using Equation 2 for frequency bands associated with TDD as shown in Equation 4 below and for frequency bands associated with FDD as shown in Equation 5.

The UE 115-a may also calculate the total baseband processing capability 225 using Equation 1 and the total radio frequency processing capability 230 using Equation 3 for the frequency bands associated with TDD separately for the frequency bands associated FDD in a similar fashion as shown above in Equation 4 and Equation 5. Additionally, or alternatively, the UE 115-a may transmit or signal the aggregated capability message 215 to the network entity 105-a for both the frequency bands associated with TDD and the frequency bands associated with FDD.

Further, in some examples, the UE 115-a may be capable of dynamically (e.g., flexibly) indicating the total baseband processing capability 225 or the total radio frequency processing capability 230 via the aggregated capability message 215. For example, when calculating the total processing capability 220 for the aggregated capability message 215, the UE 115-a may use an index, Z, when calculating the total processing capability 220 to indicate either the total baseband processing capability 225 or the total radio frequency processing capability 230 via the aggregated capability message 215. Thus, the UE 115-a may use a first index value (e.g., Z=1) to indicate the total baseband processing capability 225 and a second index value (e.g., Z=2) to indicate the total radio frequency processing capability 230. Thus, in some cases, the UE 115-a may calculate the total processing capability 220 of the UE 115-a for the aggregated capability message 215 using the index, Z, for both the frequency bands associated with TDD and FDD. In some cases, the UE 115-a may calculate the total processing capability 220 of the UE 115-a for the aggregated capability message 215 using the index, Z, separately for the frequency bands associated with TDD as shown by Equation 6 below and the frequency bands associated with FDD as shown by Equation 7 below.

Thus, the UE 115-a may use Equation 6 and Equation 7 to dynamically indicate the total baseband processing capability 225 or the total radio frequency processing capability 230 via the aggregated capability message 215 where the UE 115-a may report either a first value (e.g., 1) or a second value (e.g., 2) for the index, Z. Moreover, the UE 115-a may transmit the aggregated capability message 215 using the techniques of the present disclosure for intra-band carrier aggregation (e.g., the aggregation of two or more component carriers within a single wireless band) , inter-band carrier aggregation (e.g., the aggregation of two or more component carriers within two or more wireless bands) , or for dual connectivity modes as described elsewhere herein with reference to FIG. 1. Additionally, or alternatively, the UE 115-amay transmit the aggregated capability message 215 to indicate the total processing capability 220 of the UE 115-a for uplink communications, downlink communications, or both. Thus, in some cases, the UE 115-a may transmit a first aggregated capability message 215 to indicate the uplink communication capabilities of the UE 115-a and a second aggregated capability message 215, that is different from the first aggregated capability message 215, to indicate the downlink communication capabilities of the UE 115-a. In some other cases, the UE 115-a may transmit the aggregated capability message 215 to indicate both the uplink and the downlink communication capabilities of the UE 115-a.

Therefore, using the techniques of the present disclosure, the network entity 105-a may receive the aggregated capability message 215 from the UE 115-a such that the network entity 105-a can transmit scheduling information 235 in accordance with the aggregated capability message 215. Further, the scheduling information 235 may be for the communication between the UE 115-a and the network entity 105-a via one or more component carriers of the set of component carriers. In some cases, the scheduling information 235 may configure the UE 115-a with a band combination configuration for the UE 115-a that is in accordance with the aggregated capability message 215. That is, the baseband configuration indicated via the scheduling information 235 may be based on the aggregated capability message 215 indicating that the UE 115-a is capable of supporting the band combination configuration. For example, the UE 115-a may receive the scheduling information 235 that indicated a first band combination configuration (e.g., 100 MHz + 40 MHz + 60 MHz) or a second band combination configuration (e.g., 80 MHz + 80 MHz + 40 MHz) within the capability indicated via the aggregated capability message 215 (e.g., 200 MHz) .

Thus, using the scheduling information 235, the UE 115-a may be capable of communicating with the network entity 105-a via the uplink communication link 205 and the downlink communication link 210 relatively more efficiently. Therefore, the techniques of the present disclosure may enable the UE 115-a to reduce the signaling overhead of indicating the capabilities of the UE 115-a for communications between the UE 115-a and the network entity 105-a via the set of one or more component carriers, resulting in an increase in efficiency and reliability and a decrease in latency within the wireless communications system 200. Further descriptions of the techniques of the present disclosure may be described elsewhere herein, such as with reference to FIG. 3.

FIG. 3 shows an example of a process flow 300 that supports aggregated capability signaling for carrier aggregation and dual connectivity modes in accordance with one or more aspects of the present disclosure. In some examples, the process flow 300 may implement or be implemented by the wireless communications system 100, the wireless communications system 200, or both. For example, the process flow 300 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 300, 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 300, 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 300, some aspects of some operations may also be performed by one or more other wireless devices.

At 305, the UE 115-b may transmit an aggregated capability message to the network entity 105-b for communications between the UE 115-b and the network entity 105-b via a set of component carriers. Further, the aggregated capability message may indicate a total processing capability of the UE 115-b for the set of component carriers. In some examples, the total processing capability of the UE 115-b may include a total baseband processing capability of the UE 115-b for the set of component carriers that is based on one or more transmission parameters. In some cases, the one or more transmission parameters may include a maximum channel bandwidth for each respective component carrier of the set of component carriers, an SCS for each respective component carrier of the set of component carriers, a maximum quantity of uplink MIMO layers, downlink MIMO layers, or both for each respective component carrier of the set of component carriers, a modulation order for each respective component carrier of the set of component carriers, or any combination thereof. In some other cases, the one or more transmission parameters may include a maximum channel bandwidth for each respective SCS of a set of SCSs for the set of component carriers where the maximum channel bandwidth that the SCSs are based on a maximum quantity of uplink MIMO layers, downlink MIMO layers, or both and on a maximum modulation order being equal or the same for each respective component carrier of the set of component carriers.

In some other examples, the total processing capability of the UE 115-b may include a total radio frequency processing capability of the UE 115-b for the set of component carriers based on a maximum channel bandwidth for each respective SCS of a set of SCSs that the UE 115-b is capable of supporting. Further, in some cases the total processing capability of the UE 115-b for the set of component carriers may include a first capability that is applicable to one or more frequency bands associated with TDD and a second capability applicable to one or more frequency bands associated with FDD. In some other cases, the total processing capability of the UE 115-b may include a single capability that is applicable to both TDD bands and FDD bands.

In another example, the total processing capability of the UE 115-b may include one or more of an indication of the total baseband processing capability of the UE 115-b for the set of component carriers, an indication of the total radio frequency processing capability of the UE 115-b for the set of component carriers, or a combination thereof. In addition, the total processing capability of the UE 115-b may indicate the total baseband processing capability of the UE 115-b for the set of component carriers based on an index having a first value and the total processing capability of the UE 115-b may indicate the total radio frequency processing capability of the UE 115-b for the set of component carriers based on the index having a second value. Further, the UE 115-b may transmit the aggregated capability message based on the UE 115-b supporting carrier aggregation, dual connectivity modes, or both. Additionally, or alternatively, the UE 115-b may transmit the aggregated capability message for intra-band carrier aggregation, inter-band carrier aggregation, a dual connectivity mode, or any combination thereof. That is, the aggregated capability message may be applicable to one or more of intra-band carrier aggregation, inter-band carrier aggregation, a dual connectivity mode, or any combination thereof.

At 310, the UE 115-b may receive scheduling information from the network entity 105-b for the communications between the UE 115-b and the network entity 105-b via one or more component carriers of the set of component carriers. Further, the scheduling information may be in accordance with the aggregated capability message transmitted at 305. In some examples, the scheduling information may indicate a baseband combination configuration that is in accordance with the aggregated capability message. Therefore, at 315, the UE 115-b may communicate with the network entity 105-b via the one or more component carriers of the set of component carriers in accordance with the scheduling information received from the network entity 105-b.

A processor may also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration) . Any functions or operations described herein as being capable of being performed by a processor may be performed by multiple processors that, individually or collectively, are capable of performing the described functions or operations.

The functions described herein may be implemented using hardware, software executed by a processor, firmware, or any combination thereof. If implemented using software executed by a processor, the functions may be stored as or transmitted using one or more instructions or code of a computer-readable medium. Other examples and implementations are within the scope of the disclosure and appended claims. For example, due to the nature of software, functions described herein may be implemented using software executed by a processor, hardware, firmware, hardwiring, or combinations of any of these. Features implementing functions may also be physically located at various positions, including being distributed such that portions of functions are implemented at different physical locations.

Computer-readable media includes both non-transitory computer storage media and communication media including any medium that facilitates transfer of a computer program from one location to another. A non-transitory storage medium may be any available medium that may be accessed by a general-purpose or special-purpose computer. By way of example, and not limitation, non-transitory computer-readable media may include RAM, ROM, electrically erasable programmable ROM (EEPROM) , flash memory, compact disk (CD) ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other non-transitory medium that may be used to carry or store desired program code means in the form of instructions or data structures and that may be accessed by a general-purpose or special-purpose computer or a general-purpose or special-purpose processor.

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, ” and “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 figures, 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.
