Capability reporting based on wireless device cooperation

Abstract

Methods, systems, and devices for wireless communication are described. A UE can cooperate with a group of one or more other UEs, where each UE can operate as a panel in a wireless communication system. To ensure that updated information based on the UE's cooperation status is provided to the network, the UE can receive one or more capability request messages from a base station. The UE can determine a group cooperation capability of the UE based on a current group cooperation status of the UE. The group cooperation status can be based on the UE operating in cooperation with a group of UEs to communicate with the base station. The UE can then transmit one or more messages to the base station indicating the group cooperation capability of the UE.

Description

Technical Field

[0001] The following content relates to wireless communication, including reports on capabilities based on wireless device collaboration. Background Technology

[0002] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, message sending and receiving, broadcasting, and so on. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth-generation (4G) systems (such as Long Term Evolution (LTE) systems, LTE-A Advanced (LTE-A) systems, or LTE-A Pro systems) and fifth-generation (5G) systems, which may be referred to as New Radio (NR) systems. These systems can employ various technologies, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal FDMA (OFDMA), or Discrete Fourier Transform Extended Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations or one or more network access nodes, each of which simultaneously supports communication from multiple communication devices, which may also be referred to as User Equipment (UE).

[0003] In some wireless communication systems, a base station can communicate with multiple UEs that act as a distributed panel set or otherwise operate as such a distributed panel set. The multiple UEs may communicate with each other periodically or work collaboratively (e.g., as a single unit), and may operate as a distributed panel set based on such periodic communication or collaborative work. In some examples, collaboration among the UEs can be achieved through one or more communication links between them (e.g., sidelink communication links). However, these communication links may have varying quality, which could affect the ability of one or more UEs to perform collaboratively.

[0004] Overview

[0005] The described technology relates to improved methods, systems, devices, and apparatuses for supporting capability reporting based on wireless device cooperation. Typically, the described technology provides dynamic signaling of UE capability information in a wireless communication system based on whether a UE is cooperating with other UEs. For example, a UE may cooperate with a group of one or more other UEs, where each UE may operate as a panel in the wireless communication system. To ensure that updated information based on the UE's cooperation status is provided to the base station, the UE may receive one or more capability request messages from the base station, and the UE may transmit one or more messages indicating the UE's capabilities based on its cooperation status. In this scenario, the UE may determine its group cooperation capability based on its current group cooperation status, which may be based on whether the UE is operating cooperatively with a group of UEs to communicate with the base station. In one example, a first group cooperation status (and corresponding capability) may be associated with the UE operating cooperatively with at least one other UE, while a different second group cooperation status (and corresponding capability) may correspond to the UE not cooperating with other UEs. The UE may then transmit one or more messages indicating the UE's group cooperation capability to the base station.

[0052] Detailed description

[0053] In wireless communication systems, a single UE can cooperate with other UEs in a group, such as each UE acting as an antenna in an antenna array or a panel in a distributed panel set. In one example, a group of UEs can cooperate (e.g., combine antenna resources, share downlink information received from the network) to improve the link reliability and throughput of at least one UE in the group. UEs can communicate with each other in cooperative mode, for example, using device-to-device or sidelink communication technologies. For example, a UE can communicate with other UEs via a sidelink communication channel. However, the quality of sidelink communication links between UEs may vary over time, and in some cases, a relatively degraded quality of one or more corresponding sidelinks between UEs may affect the ability of one or more UEs to cooperate. Such a disruption in cooperation may cause a change in the number of UEs cooperating at a given time.

[0054] As a result, the capabilities of a UE (e.g., based on whether it is cooperating with other UEs) may change over time, potentially affecting reliability and throughput. Furthermore, the network may be unaware of the UE's changing cooperation status over time. Conversely, the network may also be unaware of the UE's changing capabilities over time. This lack of information on the network can further impact communication efficiency within the system.

[0055] As described above, in order to notify the network of accurate capability information of a UE, UEs in a UE group can dynamically indicate their capabilities. A UE's capabilities can be based on whether it is operating cooperatively with other UEs in the group. For example, a UE can transmit an indication of a first capability to the base station, indicating cooperation with one or more other UEs. Then, at a different time, the UE can transmit another indication of a second capability, indicating that it is operating without cooperation with other UEs (e.g., operating alone, operating in a non-cooperative mode). In either case, a UE's capabilities can change based on whether it is cooperating with other UEs (e.g., more / fewer panels available for receiving downlink communication, the UE using different time / frequency resources or bandwidths for communication, the UE having different capabilities for switching bandwidth portions, and other examples).

[0056] Here, the first capability can correspond to an additional capability relative to the second capability, such as a relatively large number of multiple-input multiple-output (MIMO) layers supported by the UE and implemented through cooperation. Thus, the report provided to the base station can include an indication of whether the UE is currently cooperating within a group of UEs. In some examples, the base station can transmit a request for UE capabilities, and the UE can, in response, transmit a capability report indicating its current capabilities based on whether it is cooperating within a group of UEs. In some cases, the UE can report its capabilities periodically, or the UE can include indications to the base station regarding changes in its capabilities over time, thereby triggering additional capability requests from the base station. In some cases, the base station can transmit requests for capability information to the UE in a periodic manner.

[0057] Alternatively, the UE may include an indication of a timer based on its cooperation state in its transmission to the base station. Upon expiration of the timer, the base station may then request updated capability information from the UE. The UE may also request activation or deactivation of one or more communication parameters (number of panels, one or more carriers) based on its cooperation state.

[0058] Therefore, the base station can be aware of the dynamic changes in the UE's ability to cooperate with other UEs in the group. The base station can then consistently monitor these changes in cooperation within the UE group and may be able to support UE cooperation more efficiently.

[0059] The aspects of this disclosure are initially described in the context of a wireless communication system. Then, the aspects of this disclosure are described in relation to a process flow. The aspects of this disclosure are further explained and described by means of, and with reference to, apparatus diagrams, system diagrams, and flowcharts relating to capability reports based on wireless device cooperation.

[0060] Figure 1Example 100 of a wireless communication system supporting capabilities reporting based on wireless device collaboration according to various aspects of this disclosure is described. Wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, wireless communication system 100 may be a Long Term Evolution (LTE) network, an Advanced LTE (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, wireless communication system 100 may support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low latency communication, communication with low-cost and low-complexity devices, or any combination thereof.

[0061] Base station 105 can be distributed across a geographical area to form wireless communication system 100, and can be different types of devices or devices with different capabilities. Base station 105 and UE 115 can communicate wirelessly via one or more communication links 125. Each base station 105 can provide a coverage area 110, and UE 115 and base station 105 can establish one or more communication links 125 on the coverage area 110. Coverage area 110 can be an example of a geographical area over which base station 105 and UE 115 can support signal communication according to one or more radio access technologies.

[0062] Each UE 115 can be distributed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 can be stationary or mobile, or stationary and mobile at different times. Each UE 115 can be a different type of device or a device with different capabilities. Figure 1 The document describes some example UE 115s. The UE 115 described herein can communicate with various types of devices, such as other UE 115s, base station 105, or network equipment (e.g., core network nodes, relay equipment, integrated access and backhaul (IAB) nodes, or other network equipment). Figure 1 As shown in the image.

[0063] Each base station 105 may communicate with the core network 130, or with each other, or both. For example, base station 105 may interface with the core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). Base stations 105 may communicate with each other directly (e.g., directly between base stations 105), indirectly (e.g., via the core network 130), or directly and indirectly on backhaul links 120 (e.g., via X2, Xn, or other interfaces). In some examples, backhaul link 120 may be or include one or more radio links.

[0064] One or more of the base stations 105 described herein may include, or may be referred to by those skilled in the art as, base transceiver station, radio base station, access point, radio transceiver, B node, evolved B node (eNB), next-generation B node or gigabit B node (any of which may be referred to as gNB), home B node, home evolved B node, or other suitable terms.

[0065] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or any other suitable term, wherein "device" may also be referred to as a unit, station, terminal, or client, etc. UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine-type communication (MTC) device, which may be implemented in various objects such as appliances or vehicles, meters, etc.

[0066] The UE 115 described herein can communicate with various types of devices, such as other UEs 115 that sometimes act as relays, as well as base station 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, relay base stations, etc. Figure 1 As shown in the image.

[0067] UE 115 and base station 105 can wirelessly communicate with each other via one or more communication links 125 on one or more carriers. The term "carrier" can refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion of the radio spectrum band (e.g., a bandwidth portion (BWP)) operating according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating carrier operation, user data, or other signaling. Wireless communication system 100 may support communication with UE 115 using carrier aggregation or multi-carrier operation. UE 115 may be configured to have multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation can be used in conjunction with frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0068] In some examples (e.g., in a carrier aggregation configuration), the carrier may also have acquisition signaling or control signaling to coordinate the operation of other carriers. The carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Frequency Channel Number (EARFCN)) and may be located according to a channel grid for discovery by UE 115. The carrier may operate in an autonomous mode in which initial acquisition and connection can be performed by UE 115 via that carrier, or in a non-autonomous mode in which the carrier may connect to carriers anchored using different carriers (e.g., different carriers of the same or different radio access technologies).

[0069] The communication link 125 shown in the wireless communication system 100 may include uplink transmission from UE 115 to base station 105, or downlink transmission from base station 105 to UE 115. The carrier may carry downlink or uplink communication (e.g., in FDD mode), or may be configured to carry both downlink and uplink communication (e.g., in TDD mode).

[0070] A carrier may be associated with a specific bandwidth of the radio frequency spectrum, and in some examples, the carrier bandwidth may be referred to as the carrier or the “system bandwidth” of the wireless communication system 100. For example, the carrier bandwidth may be one of several defined bandwidths (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz) of a carrier for a particular radio access technology. Devices of the wireless communication system 100 (e.g., base station 105, UE 115, or both) may have a hardware configuration that supports communication over a specific carrier bandwidth, or may be configurable to support communication over a single carrier bandwidth within a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate over a portion (e.g., a subband, BWP) or all of the carrier bandwidth.

[0071] The signal waveform transmitted on the carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform extended OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element may include a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the code rate of the modulation scheme, or both). Thus, the more resource elements the UE 115 receives and the higher the order of the modulation scheme, the higher the data rate the UE 115 can achieve. Wireless communication resources can refer to a combination of radio frequency spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and using multiple spatial layers can further improve the data rate or data integrity of communication with the UE 115.

[0072] One or more parameter designs for a carrier can be supported, where the parameter design may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier can be divided into one or more BWPs with the same or different parameter designs. In some examples, UE 115 can be configured with multiple BWPs. In some examples, a single BWP for a carrier can be active at a given time, and communication for UE 115 can be limited to one or more active BWPs.

[0073] The time interval of base station 105 or UE 115 can be expressed as a multiple of a basic time unit, such as the sampling period T. s =1 / (Δf) max ·Nf) seconds, where Δf max This can represent the maximum supported subcarrier spacing, while N f This can represent the maximum supported Discrete Fourier Transform (DFT) size. The time interval of the communication resources can be organized according to radio frames, each with a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0074] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may (e.g., in the time domain) be divided into subframes, and each subframe may be further divided into several time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include several symbol periods (e.g., depending on the length of the cyclic prefix added before each symbol period). In some wireless communication systems 100, time slots may be further divided into multiple mini-time slots containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N) symbols.f (Number) sampling periods. The duration of a symbol period can depend on the subcarrier interval or the operating frequency band.

[0075] A subframe, time slot, mini-slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)).

[0076] Physical channels can be multiplexed on a carrier using various techniques. Physical control channels and physical data channels can be multiplexed on a downlink carrier, for example, using one or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or a hybrid TDM-FDM technique. A control region (e.g., a control resource set (CORESET)) for physical control channels can be defined by the number of symbol periods and can extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) can be configured for a set of UEs 115. For example, one or more of the UEs 115 can monitor or search control regions for control information based on one or more search space sets, and each search space set can include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. An aggregation level for control channel candidates can refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with coded information in a control information format having a given payload size. The search space set may include a common search space set configured to send control information to multiple UEs 115 and a UE-specific search space set configured to send control information to a specific UE 115.

[0077] Each base station 105 may provide communication coverage via one or more cells (e.g., macrocells, small cells, hotspots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity used to communicate with base station 105 (e.g., on a carrier) and may be associated with an identifier used to distinguish adjacent cells (e.g., Physical Cell Identifier (PCID), Virtual Cell Identifier (VCID), or others). In some examples, a cell may also refer to a geographic coverage area 110 or a portion of geographic coverage area 110 (e.g., a sector) on which a logical communication entity operates. The extent of such cells may vary from smaller areas (e.g., structures, subsets of structures) to larger areas depending on various factors (such as the capabilities of base station 105). For example, a cell may be or include buildings, subsets of buildings, or external space between or overlapping geographic coverage areas 110, among other examples.

[0078] Macrocells typically cover a relatively large geographic area (e.g., a radius of several kilometers) and allow unrestricted access for UEs 115 that have service subscriptions with a network provider supporting the macrocell. Small cells may be associated with a lower-power base station 105 (compared to macrocells) and may operate in the same or different (e.g., licensed or unlicensed) frequency bands as macrocells. Small cells may provide unrestricted access to UEs 115 that have service subscriptions with a network provider, or may provide restricted access to UEs 115 associated with the small cell (e.g., UEs 115 in a Closed Subscriber Group (CSG), or UEs 115 associated with a user in a home or office). Base station 105 may support one or more cells and may also support communication on one or more cells using one or more component carriers.

[0079] In some examples, a carrier can support multiple cells and can be configured with different cells based on different protocol types that can provide access for different types of devices (e.g., MTC, Narrowband IoT (NB-IoT), Enhanced Mobile Broadband (eMBB)).

[0080] In some examples, base station 105 may be mobile, and thus provide communication coverage to mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but the different geographic coverage areas 110 may be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. Wireless communication system 100 may include, for example, a heterogeneous network, in which different types of base stations 105 use the same or different radio access technologies to provide coverage to various geographic coverage areas 110.

[0081] The wireless communication system 100 can support synchronous or asynchronous operation. For synchronous operation, base stations 105 can have similar frame timing, and transmissions from different base stations 105 can be approximately time-aligned. For asynchronous operation, base stations 105 can have different frame timing, and transmissions from different base stations 105 may not be time-aligned in some examples. The techniques described herein can be used for both synchronous and asynchronous operation.

[0082] Some UE 115 devices (such as MTC or IoT devices) can be low-cost or low-complexity devices and can provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC can refer to data communication technologies that allow devices to communicate with each other or with base station 105 without human intervention. In some examples, M2M communication or MTC may include communication from devices that have integrated sensors or meters to measure or capture information and relay such information to a central server or application that uses the information or presents it to people interacting with the application. Some UE 115 devices may be designed to collect information or automate the behavior of machines or other devices. Examples of applications for MTC devices include: smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wilderness survival monitoring, weather and geographic event monitoring, queue management and tracking, remote security sensing, physical access control, and transaction-based commercial toll collection.

[0083] Some UEs 115 can be configured to operate in reduced-power modes, such as half-duplex communication (e.g., a mode that supports unidirectional communication via transmission or reception but not simultaneous transmission and reception). In some examples, half-duplex communication can be performed at a reduced peak rate. Other power-saving techniques for UEs 115 include entering a power-saving deep sleep mode when not engaged in active communication, operating on limited bandwidth (e.g., according to narrowband communication), or a combination of these techniques. For example, some UEs 115 can be configured to operate using a narrowband protocol type associated with a defined portion or range (e.g., subcarriers or resource block (RB) set) within the carrier, within the carrier's guard band, or outside the carrier.

[0084] Wireless communication system 100 may be configured to support ultra-reliable communication or low latency communication, or various combinations thereof. For example, wireless communication system 100 may be configured to support ultra-reliable low latency communication (URLLC) or mission-critical communication. UE 115 may be designed to support ultra-reliable, low latency, or mission-critical functions (e.g., mission-critical functions). Ultra-reliable communication may include private or group communication and may be supported by one or more mission-critical services, such as Mission-Critical Talk-to-Talk (MCPTT), Mission-Critical Video (MCVideo), or Mission-Critical Data (MCData)). Support for mission-critical functions may include prioritization of services, and mission-critical services may be used for public safety or general business applications. The terms ultra-reliable, low latency, mission-critical, and ultra-reliable low latency are used interchangeably herein.

[0085] In some examples, UE 115 may also be able to communicate directly with other UE 115 on a device-to-device (D2D) communication link 135 (e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UE 115s utilizing D2D communication may be within the geographic coverage area 110 of base station 105. Other UE 115s in such a group may be outside the geographic coverage area 110 of base station 105 or may be unable to receive transmissions from base station 105 for other reasons. In some examples, groups of UE 115s communicating via D2D communication may utilize a one-to-many (1:M) system, where each UE 115 transmits to every other UE 115 in the group. In some examples, base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between the individual UE 115s without involving base station 105.

[0086] In some systems, the D2D communication link 135 may be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, vehicles may communicate using vehicle-to-vehicle (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these communications. Vehicles may signal information related to traffic conditions, signaling, weather, safety, emergencies, or any other information relevant to the V2X system. In some examples, vehicles in a V2X system may communicate via vehicle-to-network (V2N) communication through one or more network nodes (e.g., base station 105) with roadside infrastructure (such as roadside units), or with the network, or with both.

[0087] Core network 130 provides user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an evolved packet core (EPC) or a 5G core (5GC). The EPC or 5GC may include at least one control plane entity (e.g., a Mobility Management Entity (MME), Access and Mobility Management Function (AMF)) managing access and mobility, and at least one user plane entity (e.g., a Serving Gateway (S-GW), Packet Data Network (PDN) Gateway (P-GW), or User Plane Function (UPF)) routing packets or interconnecting to external networks. The control plane entity manages non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by base station 105 associated with core network 130. User IP packets can be delivered through the user plane entity, which provides IP address allocation and other functions. The user plane entity may be connected to one or more network operator IP services 150. The IP service 150 may include access to the Internet, intranet, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0088] Some network devices (such as base station 105) may include sub-components, such as access network entity 140, which may be an example of an access node controller (ANC). Each access network entity 140 may communicate with each UE 115 through one or more other access network transport entities 145, which may be referred to as a radio headend, smart radio headend, or transmit / receive point (TRP). Each access network transport entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio headends and ANCs) or combined into a single network device (e.g., base station 105).

[0089] Wireless communication system 100 can operate using one or more frequency bands in the range of 300 MHz to 300 GHz. Generally, the 300 MHz to 3 GHz band is referred to as a UHF band or decimeter band because the wavelengths range from about 1 decimeter to 1 meter. UHF waves can be blocked or redirected by buildings and environmental features, but these waves can penetrate various structures sufficiently for macrocells to provide service to UE 115 located indoors. Compared to transmissions using smaller frequencies and longer waves in the lower HF or VHF portions of the spectrum below 300 MHz, UHF wave transmission can be associated with smaller antennas and shorter ranges (e.g., less than 100 km).

[0090] The wireless communication system 100 can also operate in the ultra-high frequency (SHF) zoning using a frequency band from 3 GHz to 30 GHz (also known as the centimeter band) or in the extremely high frequency (EHF) zoning using a spectrum (e.g., from 30 GHz to 300 GHz) (also known as the millimeter band). In some examples, the wireless communication system 100 can support millimeter-wave (mmW) communication between the UE 115 and the base station 105, and the EHF antennas of the corresponding devices can be smaller and more closely spaced than UHF antennas. In some examples, this can facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may suffer even greater atmospheric attenuation and shorter range than SHF or UHF transmissions. The techniques disclosed herein can be employed across transmissions using one or more different frequency zonings, and the frequency band usage specified across these frequency zonings may vary by country or regulatory authority.

[0091] Wireless communication system 100 may utilize both licensed and unlicensed radio spectrum bands. For example, wireless communication system 100 may employ licensed assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in unlicensed frequency bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band). When operating in unlicensed radio spectrum bands, devices (such as base station 105 and UE 115) may employ carrier sensing for collision detection and avoidance. In some examples, operation in unlicensed frequency bands may be based on carrier aggregation configuration (e.g., LAA) in coordination with component carriers operating in licensed frequency bands. Operation in unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, etc.

[0092] Base station 105 or UE 115 may be equipped with multiple antennas that can be used to employ technologies such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels that can support MIMO operation 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, the antennas or antenna arrays associated with base station 105 may be located in different geographical locations. Base station 105 may have an antenna array with several rows and columns of antenna ports that base station 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals transmitted via the antenna ports.

[0093] Base station 105 or UE 115 can use MIMO communication to leverage multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. This technique is known as spatial multiplexing. For example, a transmitting device may transmit multiple signals via different antennas or different combinations of antennas. Similarly, a receiving device may receive multiple signals 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 bits 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), where multiple spatial layers are transmitted to the same receiving device; and multi-user MIMO (MU-MIMO), where multiple spatial layers are transmitted to multiple devices.

[0094] Beamforming (also known as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., base station 105, UE 115) to shape or guide an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array, such that some signals propagating relative to a particular orientation of the antenna array experience constructive interference, while others experience destructive interference. Adjustments to the signals transmitted via the antenna elements may include the transmitting or receiving device applying amplitude offset, phase offset, or both to the signals carried via the antenna elements associated with that device. The adjustments associated with each antenna element may be defined by a beamforming weight set associated with a particular orientation (e.g., the antenna array relative to the transmitting or receiving device, or relative to some other orientation).

[0095] Base station 105 or UE 115 may use beamsweeping techniques as part of beamforming operations. For example, base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times by base station 105 in different directions. For example, base station 105 may transmit signals according to different beamforming weight sets associated with different transmission directions. Transmissions in different beam directions may be used (e.g., by the transmitting device (such as base station 105) or the receiving device (such as UE 115)) to identify the beam direction that base station 105 will use for later transmission or reception.

[0096] Some signals (such as data signals associated with a specific receiving device) may be transmitted by base station 105 in a single beam direction (e.g., the direction associated with the receiving device (such as UE 115)). In some examples, the beam direction associated with transmission along a single beam direction may be determined based on the signals transmitted in one or more beam directions. For example, UE 115 may receive one or more signals transmitted by base station 105 in different directions and may report to base station 105 an indication of the signals received by UE 115 with the highest signal quality or other acceptable signal quality.

[0097] In some examples, transmissions performed by a device (e.g., by base station 105 or UE 115) may be executed using multiple beam directions, and the device may use a combination of digital precoding or radio frequency beamforming to generate combined beams for transmission (e.g., from base station 105 to UE 115). UE 115 may report feedback indicating precoding weights for one or more beam directions, and this feedback may correspond to a configured number of beams across the system bandwidth or one or more subbands. Base station 105 may transmit reference signals that may be precoded or unprecoded (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)). UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., multi-panel type codebook, linear combination type codebook, port selection type codebook). Although these techniques are described with reference to signals transmitted by base station 105 in one or more directions, UE 115 may use similar techniques to transmit signals multiple times in different directions (e.g., to identify the beam direction used by UE 115 for subsequent transmission or reception) or to transmit signals in a single direction (e.g., to transmit data to a receiving device).

[0098] A receiver device (e.g., UE 115) may attempt multiple receive configurations (e.g., directional listening) when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105. For example, the receiver device may attempt multiple receive directions by: receiving via different antenna subarrays; processing received signals according to different antenna subarrays; receiving according to different sets of receive beamforming weights applied to signals received at multiple antenna elements of the antenna array (e.g., different directional listening weight sets); or processing received signals according to different sets of receive beamforming weights applied to signals received at multiple antenna elements of the antenna array, any of which may be referred to as "listening" according to different receive configurations or receive directions. In some examples, the receiver 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 on a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or other acceptable signal quality based on listening according to multiple beam directions).

[0099] The wireless communication system 100 can be a packet-based network operating according to a layered protocol stack. In the user plane, communication at the bearer or Packet Data Convergence Protocol (PDCP) layer can be IP-based. The Radio Link Control (RLC) layer performs packet segmentation and reassembly for communication on logical channels. The Media Access Control (MAC) layer performs priority handling and multiplexes logical channels into transport channels. The MAC layer can also use error detection, error correction, or both to support MAC layer retransmissions to improve link efficiency. In the control plane, the Radio Resource Control (RRC) protocol layer can provide the establishment, configuration, and maintenance of RRC connections between the UE 115 and the base station 105 or core network 130 that support user plane data radio bearers. At the physical layer, transport channels can be mapped to physical channels.

[0100] UE 115 and base station 105 can support data retransmission to increase the likelihood of successful data reception. Hybrid Automatic Repeat Request (HARQ) feedback is a technique used to increase the likelihood of correctly receiving data on communication link 125. HARQ may include a combination of error detection (e.g., using Cyclic Redundancy Check (CRC)), forward error correction (FEC), and retransmission (e.g., Automatic Repeat Request (ARQ)). HARQ can improve MAC layer throughput in poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, the device may support simultaneous time-slot HARQ feedback, where the device can provide HARQ feedback in a specific time slot for data received in previous symbols within that time slot. In other cases, the device may provide HARQ feedback in subsequent time slots or according to a different time interval.

[0101] In some scenarios, a group of UEs 115 can periodically communicate with each other and work collaboratively (e.g., as a single unit). In this scenario, each UE 115 in the group can act as, or otherwise function as, a distributed panel in a distributed panel set, and can receive at least some of the same control information as the other UEs 115 in the group. To ensure that the network is provided with updated information based on the collaborative state of the UE 115, the UE 115 can receive one or more capability request messages from the base station 105. Additionally or alternatively, the UE 115 can signal one or more capability messages (e.g., based on some periodicity, based on one or more additional requests from the base station, based on the expiration of a timer, etc.). In such scenarios, the UE 115 can determine its group collaborative capability based on its current group collaborative state. This group collaborative state can be based on the UE 115 cooperating collaboratively with the group of UEs 115 to communicate with the base station 105. The UE 115 may then transmit one or more messages to the base station 105 indicating the group cooperation capability of the UE 115. In some cases, the message indicating the group cooperation capability of the UE 115 may indicate to the network whether the UE is cooperating with UE 115 in a group.

[0102] Figure 2 Example 200 of a wireless communication system supporting a capability report based on wireless device cooperation according to various aspects of this disclosure is described. The wireless communication system 200 may include a group of base stations 105-a and UEs 115, including UE 115-a, UE 115-b, and UE 115-c. The base station 105-a and the group of UEs 115 may be referenced. Figure 1 Examples of the corresponding devices described. For example, base station 105-a can be an example of base station 105 or a sub-component of base station 105, as referenced. Figure 1 As described. Similarly, UE 115-a, 115-b, or 115-c may be references. Figure 1 Examples of UE 115 or its sub-components are described. In some examples, base station 105-a may be a transmit-receive point (TRP).

[0103] In some examples, the group of UEs 115 can be used as, or otherwise serve as, a set of distributed panels 210, and each UE 115 in the group of UEs 115 can communicate with base station 105-a as a distributed panel 210 in the set of distributed panels 210. For example, UE 115-a can communicate with base station 105-a via panel 210-a, UE 115-b can communicate with base station 105-a via panel 210-b, and UE 115-c can communicate with base station 105-a via panel 210-c, and all panels 210 can be used by UEs 115 as a distributed panel 210 in the set of distributed panels 210. Each UE 115 can communicate with base station 105-a via communication link 230 via panel 210. For example, UE 115-a can communicate with base station 105-a using communication link 230-a (downlink communication link) and communication link 230-b (uplink communication link). As explained in the wireless communication system 200, the communication link 230 can support both uplink and downlink communication. In some respects, the communication link 230 may be an example of a Uu link (e.g., a Uu interface) between the base station 105-a and the UE 115.

[0104] Additionally, UE 115 can communicate with each other via sidelink 235 (e.g., a sidelink communication link, PC5 interface). For example, UE 115-a and UE 115-b can communicate using sidelink 235-b, UE 115-b and UE 115-c can communicate using sidelink 235-c, and UE 115-c and UE 115-a can communicate using sidelink 235-c. In some examples, UE 115 can use sidelink communication to facilitate cooperative operation or functionality between UE 115. For example, UE 115 can be an example of wireless devices capable of cooperating or collaborating, and thus can operate or function together (performing similar or complementary operations collectively). For example, this group of UE 115 can be used as a disaggregated UE, which may differ from the individual UE 115 including the co-location panel 210. A group of UEs 115 can be an example of a group of unmanned aerial vehicles (UAVs) (e.g., drones), industrial equipment, or any other devices that make operational decisions (such as driving, moving, or placement decisions) based on communication with other peer devices. In some aspects, UEs 115 can act as a distributed panel set based on having cooperative or collaborative functionality. In other words, the basis for a group of UEs 115 to serve as a distributed panel set can be related to the ability of the group of UEs 115 to cooperate or collaborate on operational decisions. Within a group of UEs 115, the UE identity (ID) or identifier can be an explicit ID (such as a Radio Network Temporary Identifier (RNTI)) or an implicit ID associated with a channel ID or reference signal ID. For example, any of the following can be used to identify UEs 115 within a group of UEs 115: beam ID, Transmission Configuration Indicator (TCI) status ID, Spatial Relationship Information ID, Detection Reference Signal (SRS) resource ID, or SRS resource set ID.

[0105] The ability of UE 115 to cooperate within a group of UE 115s can depend on the quality of sidelink 235. For example, if the quality of sidelink 235-a deteriorates (e.g., due to range, interference, or other interruptions), one or both of UE 115-a or 115-c may have difficulty cooperating within the group of UE 115s. In some examples, base station 105-a may be unaware of changes in the number of UE 115s capable of cooperating in the group, which may change over time. Furthermore, because UE 115 can have dynamically changing cooperative states, its ability to communicate with base station 105-a (e.g., one or more parameters supported by the UE) may also change over time.

[0106] To ensure that base station 105-a and the network are aware of the cooperative status within the group of UEs 115, base station 105-a can communicate with UEs 115 to request and receive indications for dynamic updates to the cooperative status. Base station 105-a can transmit one or more capability request messages 205 to one or more UEs 115 (e.g., UE 115-a) capable of cooperating within the group of UEs 115. One or more capability request messages 205 can be transmitted by base station 105-a without, for example, RRC establishment or RRC reconstruction procedures between base station 105-a and UE 115-a.

[0107] Based on the received capability request message 205, UE 115-a can transmit a cooperation capability indication 215 (e.g., an indication of group cooperation capability). The cooperation capability indication 215 may include general UE 115 capability information, which base station 105-a can use to determine the cooperation capability of UE 115-a. The cooperation capability indication 215 may also include specific cooperation capability information.

[0108] The cooperative capability of UE 115 can be based not only on the quality of sidelink 235, but also on other communication parameters of UE 115. Communication parameters may include supported bandwidth, subcarrier spacing, HARQ procedure formatting, Physical Uplink Control Channel (PUCCH) formatting, frequency hopping, Physical Uplink Shared Channel (PUSCH) repetition format, MIMO layer, and several other communication parameters. The cooperative capability indication 215 provided by UE 115 may include any combination of the capabilities of UE 115 as reported in the general and specific capability information.

[0109] In some scenarios, UE 115-a may have a cooperation capability that varies over time. In these scenarios, UE 115-a may transmit multiple cooperation capability indications 215. For example, at a first timing point, UE 115-a may transmit a cooperation capability indication 215 indicating support for several MIMO layers (e.g., two MIMO layers), which may implicitly indicate that UE 115-a is not cooperating. At a second timing point, UE 115-a may transmit a second cooperation capability indication indicating support for a different number of MIMO layers (e.g., four MIMO layers), which may implicitly indicate that UE 115-a is cooperating with one or more other UE 115s (e.g., UE 115-b or UE 115-c, or both).

[0110] In some cases, UE 115-a may report in the Cooperative Capability Indication 215 that its capabilities may change over time. For example, UE 115-a may include an indicator notifying base station 105-b of the change in its capabilities over time. For example, the indicator may be a one-bit flag. In some aspects, base station 105-a may transmit an Additional Capability Request message instructing UE 115-a to periodically transmit the updated Cooperative Capability Indication 215. In other aspects, base station 105-a may transmit an Additional Capability Request message to UE 115-a, allowing base station 105-a to receive the updated Cooperative Capability Indication 215 on demand. When UE 115-a reports its capabilities over time, UE 115-a may not expect to perform RRC establishment or RRC re-establishment procedures with base station 105-a.

[0111] In some scenarios, UE 115-a may format the cooperation capability indication 215 as a multi-level report. As an example, the cooperation capability indication 215 may indicate two capabilities at two levels. The first level may include non-cooperation-based UE capabilities (e.g., the capabilities of UE 115-a when it is not cooperating with other UE 115s), and the second level may include cooperation-based UE capabilities (e.g., the capabilities of UE 115-a when it is cooperating with at least one other UE 115). In some examples, the second level may additionally or alternatively include an indicator for changing capabilities.

[0112] In some scenarios, UE 115-a may report an indication of a timer, the expiration of which may indicate when the capabilities of UE 115-a can change. In such scenarios, UE 115-a may determine the timer based on, for example, the number of other UE 115s with which UE 115-a can cooperate, the link quality with other UE 115s, or any combination thereof. Base station 105-a may transmit an additional capability request message 205 upon the expiration of the timer, and UE 115-a may, in response, transmit an additional cooperation capability indication 215 (e.g., with updated capability information, with capability information similar to that previously reported, with different capability information, and other examples).

[0113] Additionally or alternatively, UE 115-a can be configured with multiple (e.g., two) levels of RRC configurations (e.g., UE 115-a may receive two RRC configurations from base station 105-a). For example, the first level RRC configuration may be based on UE capabilities associated with non-cooperation, and the second level may be based on UE capabilities associated with cooperation. Each level may be associated with a corresponding time alignment expiration timer. Separate failure reports can be defined for each of the first and second RRC configurations. In some examples, UE 115-a may use resources based on the first level RRC configuration to report failure events for the second level RRC configuration.

[0114] Additionally or alternatively, UE 115-a may request semi-static enable or disable support for the UE capabilities reported in Group Coordination Capability Indication 215. For example, if UE 115-a reports capabilities for multi-panel operation, UE 115-a may transmit a request to activate or deactivate a subset of the reported supported panel groups. In another example, if UE 115-a reports capabilities for carrier aggregation operation, UE 115-a may request to activate or deactivate a subset of the reported supported number (e.g., maximum, threshold number) of carriers. These requests may be transmitted via Layer 1 (L1), Layer 2 (L2), or Layer 3 (L3) signaling. In the case of L1 signaling, the request may include a failure report corresponding to an uplink control transmission, a random access transmission, or both. In the case of L2 signaling, the request may include a MAC-CE report for panel activation, panel deactivation, or a combination thereof. In the case of L3 signaling, the request may include UE assistance information. Note that other examples of L1, L2, and L3 signaling may be used, and the examples provided herein should not be construed as limiting the scope of the claims or this disclosure.

[0115] Figure 3 An example of a process flow 300 supporting capabilities reporting based on wireless device collaboration according to various aspects of this disclosure is explained. Process flow 300 may include base station 105-b, which may be as described in reference... Figure 1 and 2 The example of base station 105 described herein. Base station 105-b can also be an example of TRP. Process flow 300 also includes UE 115-d, which can be as described in reference Figure 1 and 2 An example of UE 115 is described. UE 115-d can operate cooperatively with one or more other UE 115s. UE 115-d and base station 105-b can communicate as part of a wireless communication system.

[0116] At 305, UE 115-d can receive one or more capability request messages from base station 105-b.

[0117] In 310, UE 115-d can determine its group cooperation capability based on its group cooperation state. This group cooperation state can be based on UE 115-d cooperating with a group of UE 115s to communicate with base station 105-b. UE 115-d can determine that it is cooperating with one or more UE 115s in a group of UE 115s to communicate with base station 105-b, where UE 115-d's group cooperation capability corresponds to cooperating with one or more UE 115s. UE 115-d can determine that UE 115-d and one or more UE 115s operate as a distributed panel set.

[0118] In step 315, UE 115-d may transmit a group cooperation capability indication to base station 105-b. UE 115-d may transmit the group cooperation capability indication in response to a capability request message received from base station 105-d. In some cases, UE 115-d may transmit a first group cooperation capability indication at a first time. UE 115-d may also transmit a second group cooperation capability message at a second time. No RRC establishment or RRC reconstruction procedure may occur between the time of the first group cooperation capability indication and the time of the second group cooperation capability indication. In some cases, the first group cooperation capability message may indicate that UE 115-d operates non-cooperatively with the UE 115 group (e.g., where the group cooperation state includes UE 115-d operating non-cooperatively). In these cases, the second group cooperation capability message may indicate that UE 115-d operates cooperatively with at least one UE 115 in the UE 115 group (e.g., where the group cooperation state corresponds to UE cooperative operation). In other cases, the first group cooperation capability message may instruct UE 115-d to operate cooperatively with at least one UE 115 in the UE 115 group, and the second group cooperation capability message may instruct UE 115-d to operate non-cooperatively with the UE 115 group.

[0119] In some cases, UE 115-d can also transmit indications of changed capability indicators based on UE 115-d's group cooperation status. The changed capability indicator can indicate to base station 105-b that UE 115-d's group cooperation capability can change over time.

[0120] In these scenarios, UE 115-d may receive one or more additional capability queries at 320. The additional capability query may be based on UE 115-d transmitting indications of changed capability indicators. At 325, UE 115-d may transmit one or more group collaboration capability indications in response to the additional capability query at 320.

[0121] Additionally or alternatively, UE 115-d may identify an expiration timer associated with its group cooperation capability based on its group cooperation status. In these cases, UE 115-d may transmit an indication of the expiration timer within one or more group cooperation capability indications (e.g., at 315 or 325). UE 115-d may then receive an additional capability request query based on the expiration of the expiration timer (e.g., at 320 or later). At 325 or later, UE 115-d may transmit one or more group cooperation capability indications in response to the additional capability query.

[0122] Additionally or alternatively, UE 115-d may receive additional (e.g., second) capability request messages from base station 105-b (e.g., at 320 or later), wherein the second capability request message includes an indication that UE 115-d periodically transmits one or more group cooperation capability indications (e.g., at 325). UE 115-d may subsequently periodically transmit one or more additional group cooperation capability indications (e.g., at 325 and thereafter at periodic intervals).

[0123] Figure 4 An example of process flow 400 supporting capabilities reporting based on wireless device collaboration according to various aspects of this disclosure is explained. Process flow 400 may include base station 105-c, which may be as described in reference... Figures 1 to 3 The described example is base station 105. Base station 105-c can also be an example of TRP. Process flow 400 also includes UE 115-e, which can be as described in reference Figures 1 to 3 An example of UE 115 is described. UE 115-e can operate cooperatively with one or more other UE 115s. UE 115-e and base station 105-c can communicate as part of a wireless communication system. UE 115-e and base station 105-c can perform communications in response to process flow 300 and communications described with respect to process flow 400, or perform communications of process flow 300 or process flow 400, or a combination thereof.

[0124] At 405, UE 115-e can receive one or more capability request messages from base station 105-c.

[0125] At 410, UE 115-e can determine its group cooperation capability based on its group cooperation state. This group cooperation state can be based on UE 115-e cooperating with a group of UE 115s to communicate with base station 105-c. UE 115-e can determine that it is cooperating with one or more UE 115s in a group of UE 115s to communicate with base station 105-c, where UE 115-e's group cooperation capability corresponds to cooperating with one or more UE 115s. UE 115-e can determine that UE 115-e and one or more UE 115s operate as a distributed panel set.

[0126] At 415, UE 115-e can transmit a group cooperation capability indication to base station 105-c. UE 115-e can transmit the group cooperation capability indication in response to a capability request message received from base station 105-c.

[0127] At 420, UE 115-e can receive a first RRC configuration from base station 105-c. The first RRC configuration can be associated with the group cooperation capability of UE 115-e. For example, the first RRC configuration can be associated with UE 115-e operating non-cooperatively with UE 115 in a group. In some cases, the first RRC configuration may include a first time alignment expiration timer.

[0128] At 420, UE 115-e can also receive a second RRC configuration from base station 105-c. The second RRC configuration can be associated with UE 115-e's group cooperation capability. For example, the second RRC configuration can correspond to UE 115-e operating in group cooperation with UE 115. In some cases, the second RRC configuration may include a second time alignment expiration timer that is different from the first time alignment expiration timer.

[0129] In some scenarios, at 425, UE 115-e can report a first failure report according to a first failure reporting procedure that can be based on a first RRC configuration. At 425, UE 115-e can also report a second failure report according to a second failure reporting procedure that can be based on a second RRC configuration. The first failure corresponding to the second RRC configuration can be reported in the resource corresponding to the first RRC configuration.

[0130] In some scenarios, at 425, UE 115-e may transmit a request to enable or disable one or more parameters for communicating with base station 105-c. This request may be based on UE 115-e's group cooperation capabilities. UE 115-e may also transmit a request to activate or deactivate a subset of UE 115-e's panel set. UE 115-e may transmit a request to activate or deactivate a subset of UE 115-e's supported carriers (e.g., component carriers), wherein UE 115-e can operate according to a multi-component carrier scheme. These requests may be transmitted via Layer 1, Layer 2, or Layer 3 signaling. In the case of Layer 1 signaling, the request may include a failure report corresponding to an uplink control transmission, a random access transmission, or both. In the case of Layer 2 signaling, the request may include a MAC-CE report for panel activation, panel deactivation, or a combination thereof. In the case of Layer 3 signaling, the request may include UE assistance information.

[0163] Figure 8 A diagram of a system 800 including device 805 supporting capability reporting based on wireless device collaboration, according to various aspects of this disclosure, is shown. Device 805 may be an example of device 505, device 605, or UE 115 as described herein, or a component including such devices. Device 805 may wirelessly communicate with one or more base stations 105, UE 115, or any combination thereof.

[0164] I / O controller 810 manages the input and output signals of device 805. I / O controller 810 can also manage peripheral devices not integrated into device 805. In some cases, I / O controller 810 may represent a physical connection or port to an external peripheral device. In some cases, I / O controller 810 may utilize an operating system, such as...

Memory 830 may store computer-readable, computer-executable code 835, including instructions that, when executed by processor 840, cause device 805 to perform the various functions described herein. Code 835 may be stored in a non-transitory computer-readable medium, such as system memory or other types of memory. In some cases, code 835 may not be directly executed by processor 840, but may cause a computer (e.g., when compiled and executed) to perform the functions described herein. In some cases, memory 830 may, in particular, include a basic I / O system (BIOS) that controls basic hardware or software operations, such as interaction with peripheral components or devices.

[0167] Processor 840 may include intelligent hardware devices (e.g., general-purpose processors, DSPs, CPUs, microcontrollers, ASICs, FPGAs, programmable logic devices, discrete gate or transistor logic components, discrete hardware components, or any combination thereof). In some cases, processor 840 may be configured to use a memory controller to operate a memory array. In other cases, the memory controller may be integrated into processor 840. Processor 840 may be configured to execute computer-readable instructions stored in memory (e.g., memory 830) to cause device 805 to perform various functions (e.g., supporting various functions or tasks based on wireless device cooperation capability reporting). For example, device 805 or components of device 805 may include processor 840 and memory 840 coupled to processor 830, wherein processor 840 and memory 830 are configured to perform the various functions described herein.

For example, the communication manager 820 may be configured or otherwise support means for receiving one or more capability request messages from a base station. The communication manager 820 may be configured or otherwise support means for determining the group cooperation capability of the UE based on the group cooperation state of the UE, wherein the group cooperation state is based on the UE cooperating with a group of UEs to communicate with the base station. The communication manager 820 may be configured or otherwise support means for transmitting one or more messages indicating the group cooperation capability of the UE to the base station in response to at least one of the one or more capability request messages, based on the determination.
