A first user equipment (UE) may send a group proximity message indicating that a group of UEs including a first UE and a second UE are within a defined proximity of each other. The first UE may receive a beam configuration for the group of UEs based on the group proximity message. The first UE may then communicate with a base station based on the beam configuration. For example, the first UE may be configured for beam measurement and reporting of the group.

Technical Field

[0003] The following relates generally to wireless communications, and more particularly to group indication of spatially proximate UEs. Background Art

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasting, etc. 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-Advanced (LTE-A) systems or LTE-A Pro systems, and fifth generation (5G) systems that may be referred to as new radio (NR) systems. These systems may employ techniques such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA) or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include many base stations or network access nodes, each of which simultaneously supports communication for multiple communication devices, which may be referred to as user equipment (UE).

[0005] A base station may communicate with a UE using beamforming communications. Techniques for managing UE mobility and proximity while performing beamforming communications may be improved. Summary of the invention

[0006] The described technology relates to improved methods, systems, devices and apparatuses for supporting group indication of spatially adjacent user equipment (UE). In general, the described technology provides for managing adjacent UEs. A base station can support beamforming communications with multiple UEs. In some cases, such as if the UEs are adjacent, each beam of a base station can serve multiple UEs. Each UE may not use a large amount of bandwidth for its payload, so the UEs can be frequency-division multiplexed on the same beam. Grouping spatially close UEs can provide some benefits to the base station. For example, when the base station performs beam scanning, the grouped UEs can be scanned together as a group.

[0007] To help the base station identify the UE group, the UE may send a group proximity message to the base station. The group proximity message may indicate that there are groups of UEs that are adjacent to each other. In some cases, the group proximity message may include an approximate value of the UE proximity, such as, the UE is within a specific radius. The group proximity message may include information of the UEs in the group (such as, the identifier of the UE), the identifier of the group, a proximity metric (such as, the group radius), the leader UE identifier, the UE position, or any combination thereof. For example, by sending another group proximity message, the group information may be dynamically updated. The base station may receive the group proximity message and communicate with the group of UEs based on the group proximity message. In some cases, by indicating the group of UEs, the base station is able to reduce the beam measurement and reporting overhead. For example, the base station may configure only a subset of UEs in the group for beam measurement and reporting, and the base station may use the same beam for each UE in the group. In some cases, a reference signal for UE beam measurement may be signaled to the UE of the group (e.g., only one UE of the group), and each UE in the group may measure the reference signal. In some cases, the group proximity message may reduce the beam scanning signaling overhead of the base station. For example, the base station may update the beam scanning pattern for a group of UEs rather than signaling the change to each UE individually.

[0008] A method of wireless communication by a first UE is described. The method may include sending a group proximity message indicating that a group of UEs including the first UE and a second UE are within a defined proximity of each other, receiving a beam configuration for the group of UEs based on the group proximity message, and communicating with a base station based on the beam configuration.

[0059] A base station may support beamforming communications with multiple user equipments (UEs). In some cases, each beam of a base station may serve multiple UEs. For example, if multiple UEs are adjacent, or the antenna array is divided into multiple sub-array MIMO (MU-MIMO) for multi-user (MU), each beam may serve multiple UEs. In some cases, a UE may not use a large amount of bandwidth for its payload. In this example, UEs may be grouped and served by a common beam by frequency division multiplexing the grouped UEs, so that each UE of the group is allocated a different portion of the bandwidth on the beam. Grouping spatially close UEs may provide some benefits to the base station. For example, when the base station performs beam scanning, the grouped UEs may be scanned together as a group. Therefore, there may be some advantages for the base station to identify the group of UEs 115. The technology described herein supports enhanced management of UE proximity and grouping.

[0060] For example, a UE may send a group proximity message to a base station. The group proximity message may indicate that there is a group of UEs that are adjacent to each other. In an example, the group of UEs may be in a car, on a moving robot, or on different vehicles in a queue. In some cases, the indication may include an approximation of the proximity of the UE, such as that the UE is within a certain radius. The UE may detect that other UEs are very close based on, for example, device-to-device (D2D) communication, detection of the same beacon signal, or being preconfigured as a group of related devices. The group proximity message may include information about the UEs in the group. For example, the indication may include an identifier of the UE, an identifier of the group, a proximity metric such as a group radius, a leading UE identifier, a UE location, or any combination thereof. For example, the group information may be dynamically updated by sending another group proximity message.

[0061] The base station may receive the group proximity message and communicate with the group of UEs 115 based on the group proximity message. In some cases, by indicating the group of UEs, the base station is able to reduce beam measurement and reporting overhead. For example, the base station may configure only a subset of the UEs in the group for beam measurement and reporting, and then the base station may use the same beam for each UE in the group. In some cases, a reference signal for UE beam measurement may be signaled to the UEs of the group (e.g., only one UE of the group), and each UE in the group may measure the reference signal. In some cases, the group proximity message may reduce the beam scanning signaling overhead of the base station. For example, the base station may update the beam scanning pattern of the group of UEs instead of signaling the change to each UE individually.

[0062] Aspects of the present disclosure are initially described in the context of a wireless communication system. Aspects of the present disclosure are further illustrated and described by reference to apparatus diagrams, system diagrams, and flow charts related to group indication of spatially proximate UEs.

[0063] Figure 1 An example of a wireless communication system 100 supporting group indication of spatially neighboring UEs according to aspects of the present disclosure is shown. The wireless communication system 100 includes a base station 105, a UE 115, and a core network 130. In some examples, the wireless communication system 100 may be a long term evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, or a new radio (NR) network. In some cases, the wireless communication system 100 may support enhanced broadband communications, ultra-reliable (e.g., mission-critical) communications, low-latency communications, or communications with low-cost and low-complexity devices.

[0064] The base station 105 may communicate wirelessly with the UE 115 via one or more base station antennas. The base station 105 described herein may include or may be referred to by those skilled in the art as a base transceiver, a radio base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB), a next generation NodeB or a giga-NodeB (any of which may be referred to as a gNB), a home NodeB, a home eNodeB, or some other suitable terminology. The wireless communication system 100 may include different types of base stations 105 (e.g., macro cell base stations or small cell base stations). The UE 115 described herein is capable of communicating with various types of base stations 105 and network equipment including macro eNBs, small cell eNBs, gNBs, relay base stations, etc.

[0065] Each base station 105 may be associated with a particular geographic coverage area 110 in which communications with various UEs 115 are supported. Each base station 105 may provide communications coverage for a respective geographic coverage area 110 via a communications link 125, and the communications link 125 between the base station 105 and the UE 115 may utilize one or more carriers. The communications link 125 shown in the wireless communication system 100 may include an uplink transmission from the UE 115 to the base station 105, or a downlink transmission from the base station 105 to the UE 115. Downlink transmissions may also be referred to as forward link transmissions, and uplink transmissions may also be referred to as reverse link transmissions.

[0066] The geographic coverage area 110 of the base station 105 can be divided into sectors that constitute a portion of the geographic coverage area 110, and each sector can be associated with a cell. For example, each base station 105 can provide communication coverage for a macro cell, a small cell, a hotspot, or other type of cell, or various combinations thereof. In some examples, the base station 105 can be mobile and thus provide communication coverage for a mobile geographic coverage area 110. In some examples, different geographic coverage areas 110 associated with different technologies can overlap, and overlapping geographic coverage areas 110 associated with different technologies can be supported by the same base station 105 or by different base stations 105. The wireless communication system 100 may include, for example, a heterogeneous LTE / LTE-A / LTE-APro or NR network in which different types of base stations 105 provide coverage for various geographic coverage areas 110.

[0067] The term "cell" refers to a logical communication entity used to communicate with a base station 105 (e.g., on a carrier), and may be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID)) used to distinguish between adjacent cells operating via the same or different carriers. In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types that may provide access to different types of devices (e.g., machine type communication (MTC), narrowband Internet of Things (NB-IoT), enhanced mobile broadband (eMBB), etc.). In some cases, the term "cell" may refer to a portion (e.g., a sector) of a geographic coverage area 110 on which the logical entity operates.

[0068] UE 115 may be dispersed throughout the wireless communication system 100, and each UE 115 may be fixed or mobile. UE 115 may also be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable term, where "device" may also be referred to as a unit, a station, a terminal, or a client. UE 115 may also be 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, UE 115 may also refer to a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or an MTC device, etc., which may be implemented in various items such as appliances, vehicles, meters, etc.

[0069] Some UEs 115, such as MTC or IoT devices, may be low-cost or low-complexity devices and may provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC may refer to data communication technology that allows devices to communicate with each other or with a base station 105 without human intervention. In some examples, M2M communication or MTC may include communication from devices that integrate sensors or meters to measure or capture information and relay the information to a central server or application that can utilize the information or present the information to a person interacting with the program or application. Some UEs 115 may be designed to collect information or implement automated behavior of machines. Application examples of MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based business charging.

[0070] 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 simultaneous transmission and reception). In some examples, half-duplex communications may be performed at a reduced peak rate. Other power saving techniques for UE 115 include entering a power saving "deep sleep" mode when not engaged in active communications, or operating on a limited bandwidth (e.g., in accordance with narrowband communications). In some cases, UE 115 may be designed to support critical functions (e.g., mission-critical functions), and the wireless communication system 100 may be configured to provide ultra-reliable communications for these functions.

[0071] In some cases, the UE 115 is also able to communicate directly with other UEs 115 (e.g., using a peer-to-peer (P2P) or device-to-device (D2D) protocol). One or more UEs 115 of a group of UEs 115 utilizing D2D communication may be within a geographic coverage area 110 of a base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of the base station 105, or otherwise unable to receive transmissions from the base station 105. In some cases, a group of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system, in which each UE 115 transmits to each other UE 115 in the group. In some cases, the base station 105 facilitates scheduling of resources for D2D communication. In other cases, D2D communication is performed between UEs 115 without involving the base station 105.

[0072] The base stations 105 may communicate with the core network 130 and with each other. For example, the base stations 105 may be connected to the core network 130 via a backhaul link 132 (e.g., via S1, N2, N3, or other interface). The base stations 105 may communicate with each other directly (e.g., directly between the base stations 105) or indirectly (e.g., via the core network 130) on a backhaul link 134 (e.g., via X2, Xn, or other interface).

[0073] 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), which may include at least one mobility management entity (MME), at least one serving gateway (S-GW), and at least one packet data network (PDN) gateway (P-GW). The MME may manage non-access stratum (e.g., control plane) functions such as mobility, authentication, and bearer management of UEs 115 served by base stations 105 associated with the EPC. User IP packets may be transmitted through the S-GW, which itself may be connected to the P-GW. The P-GW may provide IP address allocation and other functions. The P-GW may be connected to network operator IP services. Operator IP services may include access to the Internet, an intranet, an IP multimedia subsystem (IMS), or a packet switched (PS) streaming service.

[0074] At least some network devices, such as base stations 105, may include subcomponents, such as access network entities, which may be examples of access node controllers (ANCs). Each access network entity may communicate with UE 115 through a number of other access network transport entities, which may be referred to as radio heads, smart radio heads, or transmit / receive points (TRPs). In some configurations, the various functions of each access network entity or base station 105 may be distributed across various network devices (e.g., radio heads and access network controllers) or merged into a single network device (e.g., base station 105).

[0075] The wireless communication system 100 can operate using one or more frequency bands typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Typically, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelengths are in the range of about one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features. However, the waves can penetrate structures sufficiently to allow macro cells to provide services to UEs 115 located indoors. Transmission of UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 km) compared to transmission of smaller frequencies and longer waves using the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz.

[0076] The wireless communication system 100 may also operate in the Super High Frequency (SHF) region (also known as the centimeter band) using frequency bands from 3 GHz to 30 GHz. The SHF region includes bands such as the 5 GHz Industrial, Scientific, and Medical (ISM) band, which may be used opportunistically by devices that can tolerate interference from other users.

[0077] The wireless communication system 100 can also operate in the extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz), which is also called the millimeter wave band. In some examples, the wireless communication system 100 can support millimeter wave (mmW) communications between the UE 115 and the base station 105, and the EHF antennas of each device can be even smaller and closer than the UHF antennas. In some cases, this can facilitate the use of antenna arrays within the UE 115. However, the propagation of EHF transmissions may be subject to even greater atmospheric attenuation and a shorter range than SHF or UHF transmissions. The technology disclosed herein can be used for transmissions using one or more different frequency regions, and the bands specified for use on different frequency regions may vary from country to country or regulatory agency.

[0078] In some cases, the wireless communication system 100 can use licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 can adopt license assisted access (LAA), LTE-unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band such as the 5GHz ISM band. When operating in an unlicensed radio spectrum band, wireless devices such as base stations 105 and UE 115 can adopt a listen-before-talk (LBT) procedure to ensure that the frequency channel is clear before transmitting data. In some cases, operations in unlicensed bands can be based on a carrier aggregation configuration (e.g., LAA) combined with component carriers operating in licensed bands. Operations in unlicensed spectrum can include downlink transmissions, uplink transmissions, peer-to-peer transmissions, or a combination of these. Duplexing in unlicensed spectrum can be based on frequency division duplexing (FDD), time division duplexing (TDD), or a combination of both.

[0079] In some examples, the base station 105 or the 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. For example, the wireless communication system 100 may use a transmission scheme between a transmitting device (e.g., a base station 105) and a receiving device (e.g., a UE 115), wherein the transmitting device is equipped with multiple antennas and the receiving device is equipped with one or more antennas. MIMO communications may employ multipath signal propagation to improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers, which may be referred to as spatial multiplexing. For example, multiple signals may be transmitted by a transmitting device via different antennas or different antenna combinations. Similarly, multiple signals may be received by a receiving device via different antennas or different antenna combinations. 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. Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO technology includes single-user MIMO (SU-MIMO) that transmits multiple spatial layers to the same receiving device, and multi-user MIMO (MU-MIMO) that transmits multiple spatial layers to multiple devices.

[0080] 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 base station 105 or a UE 115) to shape or control an antenna beam (e.g., a transmit beam or a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining signals transmitted via antenna elements of an antenna array so that signals propagating in a particular direction relative to the antenna array experience constructive interference while other signals experience destructive interference. Adjustment of signals transmitted via antenna elements may include the transmitting device or the receiving device applying a particular amplitude and phase offset to a signal carried via each antenna element associated with the device. The adjustment associated with each antenna element may be defined by a set of beamforming weights associated with a particular direction (e.g., relative to the antenna array of the transmitting device or the receiving device, or relative to some other direction).

[0081] In one example, the base station 105 may use multiple antennas or antenna arrays to perform beamforming operations for directional communication with the UE 115. For example, some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be sent multiple times by the base station 105 in different directions, which may include signals sent according to different beamforming weight sets associated with different transmission directions. The transmissions in different beam directions may be used to identify (e.g., by the base station 105 or a receiving device such as the UE 115) a beam direction for subsequent transmission and / or reception by the base station 105.

[0082] Some signals, such as data signals associated with a particular receiving device, may be transmitted by base station 105 in a single beam direction (e.g., a direction associated with a receiving device such as UE 115). In some examples, the beam direction associated with transmission along a single beam direction may be determined based at least in part on signals transmitted in different beam directions. For example, UE 115 may receive one or more signals transmitted by base station 105 in different directions, and UE 115 may report to base station 105 an indication of the signal it received having the highest signal quality or an otherwise acceptable signal quality. Although these techniques are described with reference to signals transmitted by base station 105 in one or more directions, UE 115 may employ similar techniques to transmit signals multiple times in different directions (e.g., to identify a beam direction for subsequent transmission or reception by UE 115), or to transmit signals in a single direction (e.g., to transmit data to a receiving device).

[0083] A receiving device (e.g., UE 115, which may be an example of a mmW receiving device) may try multiple receive beams when receiving various signals from base station 105, such as synchronization signals, reference signals, beam selection signals, or other control signals. For example, the receiving device may try multiple receive directions by receiving via different antenna subarrays, by processing signals received according to different antenna subarrays, by receiving according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, or by processing signals received 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 beams or receive directions. In some examples, the receiving device may receive along a single beam direction using a single receive beam (e.g., when receiving a data signal). The single receive beam may be aligned with a beam direction determined based on listening according to different receive beam directions (e.g., a beam direction determined to have the highest signal strength, the highest signal-to-noise ratio, or otherwise acceptable signal quality based on listening according to multiple beam directions).

[0084] In some cases, the antennas of a base station 105 or a UE 115 may be located within one or more antenna arrays that 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 cases, the antennas or antenna arrays associated with a base station 105 may be located at different geographic locations. A base station 105 may have an antenna array with many rows and columns of antenna ports that the base station 105 may use to support beamforming for communications with a UE 115. Likewise, a UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations.

[0085] In some cases, the wireless communication system 100 can be a packet-based network operating according to a layered protocol stack. In the user plane, the communication at the bearer layer or the packet data convergence protocol (PDCP) layer can be based on IP. The radio link control (RLC) layer can perform packet segmentation and reorganization to communicate on the logical channel. The media access control (MAC) layer can perform priority processing and multiplex the logical channel into the transport channel. The MAC layer can also use hybrid automatic repeat request (HARQ) to provide retransmission at the MAC layer to improve link efficiency. In the control plane, the radio resource control (RRC) protocol layer can provide the establishment, configuration and maintenance of the RRC connection between the base station 105 or the core network 130 that supports the radio bearer of the user plane data for UE 115. At the physical layer, the transport channel can be mapped to the physical channel.

[0086] In some cases, UE 115 and base station 105 can support retransmission of data to increase the possibility of successfully receiving data. HARQ feedback is a technique to increase the possibility of correctly receiving data on communication link 125. HARQ can 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 the throughput of the MAC layer under poor radio conditions (e.g., signal-to-noise ratio conditions). In some cases, a wireless device can support simultaneous slot HARQ feedback, where the device can provide HARQ feedback for data received in a previous symbol in a specific time slot. In other cases, the device can provide HARQ feedback in a subsequent time slot or according to some other time intervals.

[0087] The time interval in LTE or NR can be expressed as a multiple of a basic time unit, for example, the basic time unit can refer to a sampling period Ts = 1 / 30,720,000 seconds. The time interval of the communication resource can be organized according to radio frames each having a duration of 10 milliseconds (ms), where the frame period can be expressed as Tf = 307,200Ts. The radio frame can be identified by a system frame number (SFN) ranging from 0 to 1023. Each frame may include 10 subframes numbered from 0 to 9, and each subframe may have a duration of 1ms. A subframe can be further divided into 2 time slots, each time slot has a duration of 0.5ms, and each time slot may contain 6 or 7 modulation symbol periods (for example, depending on the length of the cyclic prefix attached to the front of each symbol period). Excluding the cyclic prefix, each symbol period may contain 2048 sampling periods. In some cases, a subframe may be the smallest scheduling unit of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In other cases, the minimum scheduling unit of the wireless communication system 100 may be shorter than a subframe or may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs) or in selected component carriers using sTTIs).

[0088] In some wireless communication systems, a time slot may be further divided into multiple mini-slots containing one or more symbols. In some cases, a symbol of a mini-slot or a mini-slot may be the minimum unit of scheduling. For example, the duration of each symbol may vary depending on the subcarrier spacing or the frequency band of operation. In addition, some wireless communication systems may implement time slot aggregation, where multiple time slots or mini-slots are aggregated together and used for communication between UE 115 and base station 105.

[0089] The term "carrier" refers to a set of radio frequency spectrum resources having a defined physical layer structure for supporting communications on the communication link 125. For example, a carrier of the communication link 125 may include a portion of a radio frequency spectrum band that operates according to a physical layer channel of a given radio access technology. Each physical layer channel may carry user data, control information, or other signaling. A carrier may be associated with a predefined 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 a UE 115. A carrier may be a downlink or an uplink (e.g., in FDD mode), or may be configured to carry downlink and uplink communications (e.g., in TDD mode). In some examples, a signal waveform transmitted on a carrier may be composed of multiple subcarriers (e.g., using a multi-carrier modulation (MCM) technique such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)).

[0090] The organization structure of the carrier may be different for different radio access technologies (e.g., LTE, LTE-A, LTE-A Pro, NR). For example, communications on a carrier may be organized according to TTIs or time slots, each of which may include user data and control information or signaling to support decoding of the user data. A carrier may also include dedicated acquisition signaling (e.g., synchronization signals or system information, etc.) and control signaling to coordinate operations for the carrier. In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling to coordinate operations for other carriers.

[0091] Physical channels may be multiplexed on a carrier according to various techniques. Physical control channels and physical data channels may be multiplexed on a downlink carrier, for example, using a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique. In some examples, control information transmitted in a physical control channel may be distributed in a cascaded manner between different control regions (e.g., between a common control region or common search space and one or more UE-specific control regions or UE-specific search spaces).

[0092] A carrier may be associated with a particular bandwidth of the radio spectrum, and in some examples, the carrier bandwidth may be referred to as the "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of many predetermined bandwidths of a carrier for a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz). In some examples, each served UE 115 may be configured to operate on part or all of the carrier bandwidth. In other examples, some UEs 115 may be configured to operate using a narrowband protocol type associated with a predefined portion or range (e.g., a set of subcarriers or RBs) within a carrier (e.g., an "in-band" deployment of a narrowband protocol type).

[0093] In a system using MCM technology, a resource element may consist of a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and the 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). Therefore, the more resource elements received by UE 115 and the higher the order of the modulation scheme, the higher the data rate for UE 115. In a MIMO system, wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and space resources (e.g., space layers), and the use of multiple space layers may further increase the data rate for communicating with UE 115.

[0094] A device (e.g., base station 105 or UE 115) of wireless communication system 100 may have a hardware configuration that supports communication on a specific carrier bandwidth, or may be configured to support communication on one carrier bandwidth in a carrier bandwidth set. In some examples, wireless communication system 100 may include base stations 105 and / or UE 115 that support simultaneous communication via carriers associated with more than one different carrier bandwidths.

[0095] The wireless communication system 100 may support communication with the UE 115 on multiple cells or carriers, a feature that may be referred to as carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, the UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may be used with both FDD and TDD component carriers.

[0096] In some cases, the wireless communication system 100 can utilize an enhanced component carrier (eCC). An eCC can be characterized by one or more characteristics including a wider carrier or frequency channel bandwidth, a shorter symbol duration, a shorter TTI duration, or a modified control channel configuration. In some cases, an eCC can be associated with a carrier aggregation configuration or a dual connectivity configuration (e.g., when multiple serving cells have suboptimal or non-ideal backhaul links). An eCC can also be configured for use in an unlicensed spectrum or a shared spectrum (e.g., where more than one operator is allowed to use the spectrum). An eCC characterized by a wide carrier bandwidth can include one or more segments that can be used by a UE 115 that is unable to monitor the entire carrier bandwidth or is otherwise configured to use a limited carrier bandwidth (e.g., for power conservation).

[0097] In some cases, an eCC may use a different symbol duration than other component carriers, which may include using a reduced symbol duration compared to the symbol duration of other component carriers. The shorter symbol duration may be associated with an increased or decreased spacing between adjacent subcarriers. A device using an eCC, such as a UE 115 or a base station 105, may transmit a wideband signal with a reduced symbol duration (e.g., 16.67 microseconds) (e.g., based on a frequency channel or carrier bandwidth of 20, 40, 60, 80 MHz, etc.). A TTI in an eCC may consist of one or more symbol periods. In some cases, the TTI duration (i.e., the number of symbol periods in a TTI) may be variable.

[0098] The wireless communication system 100 may be an NR system that may utilize any combination of licensed, shared, and unlicensed frequency bands, etc. The flexibility of eCC symbol duration and subcarrier spacing may allow the use of eCC across multiple spectrums. In some examples, NR shared spectrum may improve spectrum utilization and spectrum efficiency, particularly through dynamic vertical (e.g., across frequency domain) and horizontal (e.g., across time domain) sharing of resources.

[0099] The base station 105 may wirelessly communicate with multiple UEs 115 using beamforming communications. In some cases, each beam of the base station 105 may serve multiple UEs 115, such as if the UEs 115 are in close proximity. Each UE 115 may not use a large amount of bandwidth for its payload, so the UEs 115 may be frequency-division multiplexed on the same beam. Grouping UEs 115 that are spatially close may provide some benefits to the base station 105. For example, when the base station 105 performs beam scanning, the grouped UEs 115 may be scanned together as a group.

[0100] To help the base station 105 identify the UE group, the UE 115 may send a group proximity message to the base station 105. The group proximity message may indicate that there are groups of UEs 115 that are in proximity to each other. In some cases, the group proximity message may include an approximation of the proximity of the UEs 115, such as the UEs 115 being within a certain radius. The group proximity message may include information of the UEs 115 in the group (such as an identifier of the UE 115), an identifier of the group, a proximity metric such as a group radius, a leader UE identifier, a UE location, or any combination thereof. The group information may be dynamically updated, for example, by sending another group proximity message.

[0101] The base station 105 may receive the group proximity message and communicate with the group of UEs 115 based on the group proximity message. In some cases, by indicating the group of UEs 115, the base station 105 is able to reduce beam measurement and reporting overhead. For example, the base station 105 may configure only a subset of the UEs 115 in the group for beam measurement and reporting, and then the base station 105 may use the same beam for each UE 115 in the group. In some cases, a reference signal for UE beam measurement may be signaled to the UEs 115 of the group (e.g., only one UE 115 of the group), and each UE 115 in the group may measure the reference signal. In some cases, the group proximity message may reduce the beam scanning signaling overhead of the base station. For example, the base station 105 may update the beam scanning pattern of the group of UEs 115 instead of signaling the change to each UE 115 individually.

[0102] Figure 2An example of a wireless communication system 200 according to aspects of the present disclosure is shown. In some examples, the wireless communication system 200 can implement aspects of the wireless communication system 100. The wireless communication system can include a base station 105-a and a UE 115, which can be as described with reference to Figure 1 Corresponding examples of base station 105 and UE 115 are described.

[0103] The wireless communication system 200 may support beamforming communications. For example, the base station 105-a may transmit directionally to the UE 115 using the transmit beam 205, and the UE 115 may monitor the transmission directionally using the receive beam. In an example, the base station 105-a may communicate with two UEs 115 in different directions from the base station 105-a. The base station 105-a may transmit to the first UE 115 using a first beam, and the base station 105-a may transmit to the second UE 115 using a second beam.

[0104] In some cases, each beam 205 (e.g., each base station beam) can serve multiple UEs 115. For example, when the UEs 115 are densely distributed (e.g., multiple UEs 115 are in close proximity) or when the antenna array is divided into multiple sub-arrays for multi-user (MU) MIMO (MU-MIMO), each beam can serve multiple UEs 115. In an example, a first beam 205-a can serve a first group 210-a of UEs 115, and a second beam 205-b can serve a second group 210-b of UEs 115. The first group 210-a of UEs 115 may include three UEs 115 (e.g., UE1, UE2, and UE3). The second group 210-b of UEs 115 may also include three UEs 115 (e.g., UE4, UE5, and UE6). In other examples, the groups 210 of UEs 115 may include different numbers of UEs 115.

[0105] In some cases, UE 115 may not use a large amount of bandwidth for its payload. For example, in an Internet of Things (IOT) system, such as an Industrial Internet of Things (IIOT) system, a scheduled UE may use a smaller bandwidth than the bandwidth allocated for its payload (e.g., a large bandwidth may not be required for its payload). Therefore, UE 115 may be grouped so that the grouped UE 115 can be served by the same beam or a close beam (e.g., close in space) by frequency division multiplexing to save the spatial dimension for multiplexing UE 115 in different directions. For example, a first group 210-a of UE 115 may be adjacent to each other and each use a relatively small amount of bandwidth for communication. Therefore, base station 105-a can communicate with a first group 210-a of UE 115 using a first beam 205-a, and each UE 115 of the first group 210-a may be allocated a different part of the bandwidth on the first beam 205-a.

[0106] Grouping spatially close UEs 115 can provide some benefits for the base station 105 to perform multi-beam scanning. For example, the grouped UEs 115 can be scanned together as a group. In some cases, the group formation can be updated based on UE and environmental mobility. For example, if UE1 is initially closest to the base station 105-a but moves to a position that is spatially farthest compared to other UEs 115 in the first group 210-a (e.g., compared to UE2 and UE3), the base station 105-a can manage and track the positions and relative positions of the UEs 115 in the first group 210-a (e.g., based on positioning reports sent by the UEs 115). The wireless communication system 200 can support techniques for managing UE and UE group proximity and positions.

[0107] For example, UE 115 may indicate to base station 105-a that there is a group 210 of UE 115 that is close to each other. UE 115 may send a group proximity message to indicate the group 210 of UE 115. In an example, a first group 210-a of UE 115 may be in a car, on a moving robot, or on different vehicles in a queue. UE1 in the first group 210-a of UE 115 may send an indication of the proximity of UE1, UE2, and UE3 to base station 105-a. In some cases, the indication may include an approximation of the proximity of UE 115, such as UE 115 being included within a certain radius (e.g., within X meters). For example, the radius may be a group radius. In some cases, a device may be considered high density within a radius of one meter, while a device may be considered normal density if it is included within a radius of two meters. In some examples, multiple UE 115 of group 210 may send a group proximity message of group 210 to base station 105-a.

[0108] UE 115 can use a variety of different techniques to detect the presence of other UE 115 in proximity. For example, UE 115 can communicate using device-to-device (D2D) communication, and two UE 115 can determine that they are in close spatial proximity based on D2D range estimation. In some cases, two UE 115 can detect the same beacon (e.g., from a single vehicle), and UE 115 can determine that they can each detect the beacon. In some cases, a fixed group of UE 115 can be installed on the same mobile object. In some examples, a fixed group of UE 115 can be preconfigured to identify a fixed group. In some cases, the UE 115 of group 210 can form a communication group, such as a UE 115 used in a vehicle platoon.

[0109] The group proximity message indicating the group 210 may include information of the UEs 115 in the group 210. For example, the indication may include an identifier of the UE 115, a proximity metric such as a group radius (e.g., proximity metric data), a leader UE ID, a UE location, or any combination thereof. In some cases, the leader UE may be identified based on proximity or other factors (e.g., capabilities, device type, etc.). The group information may be dynamically updated. For example, if a UE 115 leaves the proximity range of the group 210 (e.g., moves to a location outside the group radius), the UE 115 of the group 210 (e.g., a UE 115 that leaves the proximity range of the group 210, another UE 115 of the group 210) may send another indication including an indicator that one or more UEs 115 have left the group 210. The proximity indication of the UE may help the base station 105-a because the base station 105-a may not need to continuously poll for positioning data from each UE 115.

[0110] The base station 105-a may receive a group proximity message and communicate with the group 210 of UEs 115 based on the information in the group proximity message. In some aspects, the group proximity message may indicate that the group 210 of UEs 115 is located within a defined proximity to each other based on UE location data of one or more UEs 115 within the group 210 of UEs 115. In some examples, the base station 105-a may receive a set of UE identifiers associated with (e.g., belonging to) a particular group identifier. The base station 105-a may determine neighboring UEs 115 (e.g., based on a threshold, e.g., within a group radius) based on UE location data (e.g., a positioning report) provided by each UE 115. In some cases, by indicating the group 210 of UEs 115, the base station 105-a is able to reduce beam measurement and reporting overhead. For example, if the UE angular spread (e.g., from the base station 105-a to the UEs 115 in the group 210) is less than the base station beam width, the base station 105-a may send a beam configuration that configures a subset of the UEs 115 in the group 210 for beam measurement and reporting. The base station 105-a may then use the same base station beam 205 for all UEs 115 in the group 210.

[0111] For example, UE1, UE2, and UE3 in the first group 210-a may be close enough together (e.g., based on proximity, e.g., within a group radius) so that the UE angular spread measured at the base station 105-a is less than the width of the beam 205 of the base station 105-a. For example, if each UE 115 in the first group 210-a has a separate beam 205, the beams will overlap significantly given the beam width and proximity of the UE 115. Therefore, instead, the base station 105-a may send a beam configuration that configures only UE1 of the first group 210-a for beam measurement and reporting. The base station 105-a may select the first beam 205-a and use the first beam 205-a for each UE 115 in the first group 210-a. In some cases, the base station 105-a may determine to configure UE1 for beam measurement and reporting based on the proximity, capability, signal strength, or other factors of UE1.

[0112] A reference signal for UE beam measurement may be signaled to the UEs 115 of the first group 210-a, e.g., only one UE 115 (e.g., UE1) of the first group 210-a, and each UE 115 in the first group 210-a may measure the reference signal. For example, the base station 105-a may send a reference signal for UE beam refinement to UE1, and the same reference signal may be measured by UE2 and UE3. If the UEs 115 in the group 210 move in a predetermined pattern, the same predetermined beam switching sequence may be applied to the UE group. For example, if the group 210 of UEs 115 moves in the same direction (e.g., and maintains similar proximity, e.g., a proximity range within a threshold), the base station 105-a may switch beams and use a new beam for each UE 115 in the group 210. For example, the base station 105-a may switch from using a separate beam for each UE 115 to using the same beam for each UE 115 in the group 210.

[0113] For some UE group formations (e.g., in a vehicle platoon), the base station 105-a may send a beam configuration to configure a subset of the UEs 115 in the group 210 for beam measurement and reporting, such as the UEs 115 at the edge of the formation. In an example, two UEs 115 at two edges of the formation of the group 210 of UEs 115 may be configured for beam measurement and reporting, and other UEs 115 in the group 210 may not be configured for beam measurement and reporting. Based on the beams determined for the two UEs 115, the base station 105-a may select a beam 205 for each UE 115 in the group 210 based on their relative positions in the formation. In some aspects, the base station 105-a may provide the beam configuration for the group 210 of UEs 115 via a multicast message or a broadcast message for the group 210 of UEs 115. The multicast message or broadcast message may indicate the beam 205 selected by the base station 105-a for each UE 115 in the group 210 of UEs 115. In some aspects, the broadcast or multicast message may include group-common downlink control information (DCI) or a media access control (MAC) control element (MAC-CE). In some examples, the DCI may include a group-common DCI associated with the group 210. In some aspects, the group-common DCI may be scrambled based on a radio network temporary identifier (RNTI) associated with all UEs 115 in the group 210. The RNTI may be indicated by the base station 105-a to each UE 115 in the group 210.

[0114] In some cases, the group proximity message can reduce the beam scanning signaling overhead of the base station 105-a. The base station 105-a can update (e.g., via signaling) the same beam scanning pattern for the group 210 of UEs 115 to save separate signaling overhead. For example, instead of indicating an updated beam scanning pattern for each UE 115 in the first group 210-a, the base station 105-a can send a beam configuration that provides an indication of the updated beam scanning pattern to the UEs 115 of the first group 210-a (e.g., only to UE1). UE1 can then indicate the updated beam scanning pattern to other UEs 115 in the first group 210-a. The base station 105-a can then perform a beam scanning process according to the indicated beam scanning pattern to enable the base station 105-a, the UEs in the first group 210-a, or both to select beams for uplink and downlink transmissions.

[0115] Figure 3 An example of a process flow 300 according to aspects of the present disclosure is shown. In some examples, the process flow 300 can implement aspects of the wireless communication system 100. The process flow 300 includes a UE 115-a and a base station 105-b, which can be as described in reference Figure 1 1 and 105. UE 115-a may be spatially close to other UEs 115, forming a group 305 of UEs 115. Group 305 may include the UEs 115 and base stations 105 as described above. Figure 2 Aspects of group 210 of UEs 115 are described.

[0116] UE 115-a may identify other UEs 115 in the vicinity. For example, UE 115-a may detect other UEs 115 in the vicinity based on D2D communication, receiving a public beacon signal, etc. At 310, UE 115-a may send a group proximity message indicating that a group 305 of UEs 115 including UE 115-a and at least a second UE 115 are within a defined proximity of each other. For example, the UEs 115 of group 305 may be within a radius of one meter (e.g., for high density) or two meters (e.g., for normal density). The group proximity message may be sent to base station 105-b. In some other examples, the group proximity message may be sent to a relay node or an intermediate communication device that manages group 305.

[0117] In some cases, the group proximity message may include a group identifier for the group of UEs. In some examples, the group proximity message may include group information for the group of UEs 115. In some cases, the group information includes UE identifiers of one or more UEs within the group of UEs, proximity metric data, group radius data, a leader identifier, UE location data, or any combination thereof. At 315, UE 115-a may receive a beam configuration for the group of UEs based on the group proximity message. At 320, UE 115-a may communicate with base station 105-b based on the beam configuration.

[0118] In some cases, beam configuration may reduce beam measurement and reporting overhead for base station 105-b. For example, base station 105-b may configure UEs 115 of group 305 using beam configuration, e.g., only one UE of group 305 (e.g., UE 115-a) for beam measurement and reporting, and base station 105-b may select the same beam for all UEs 115 in group 305 based on beam measurement and reporting of UE 115-a. Base station 105-a may configure UEs 115 of group 305, e.g., only one UE 115 of group 305, if the UE angular spread of UEs 115 in group 305 is less than the width of the beam used by base station 105-a.

[0119] For example, the beam configuration may indicate a beam measurement report configuration for the group 305 of UEs 115. Then, at 320, UE 115-a may send a beam measurement report for the group 305 of UEs 115 to the base station based on the beam measurement report configuration. In some cases, UE 115-a may monitor data transmissions or control transmissions from base station 105-b via beams selected for transmission to the group 305 of UEs 115 based on the beam measurement report.

[0120] In another example, for certain UE group formations, the base station 105-b may use the beam configuration to configure a subset of the UEs 115 in the group 305 for beam measurement and reporting. For example, the base station 105-b may configure the UE 115-a and the second UE 115 for beam measurement and reporting, but the other UEs 115 in the group may not be configured for beam measurement and reporting. In an example, the beam configuration may indicate a first beam measurement report configuration for a first subset of the group of UEs and a second beam measurement report configuration for a second subset of the group of UEs. Then, at 320, the UE 115-a may send a first beam measurement report for the first subset to the base station 105-a based on the first beam measurement report configuration, and the UEs in the second subset may send a second beam measurement report for the second subset to the base station 105-a based on the second beam measurement report configuration. UE 115-a may monitor data transmission or control transmission from base station 105-b via a beam selected by base station 105-b for transmission to the first subset based on the first beam measurement report. UEs in the second subset may similarly monitor data transmission or control transmission from base station 105-b via a beam selected by base station 105-b for transmission to the second subset based on the second beam measurement report.

[0121] In addition, the base station 105-a may send a beam configuration 315 to the UE 115-a that provides an indication of the beam scanning pattern. The UE 115-a may then indicate the beam scanning pattern to other UEs 115 in the group. The base station 105-b may then perform a beam scanning procedure according to the indicated beam scanning pattern to enable the base station 105-b, the UEs in the group, or both, to select a beam for transmitting uplink and / or downlink transmissions at 320.

[0150] Figure 8 A block diagram 800 of a device 805 according to aspects of the present disclosure is shown. The device 805 may be an example of aspects of a base station 105 as described herein. The device 805 may include a receiver 810, a communication manager 815, and a transmitter 820. The device 805 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

[0151] The receiver 810 may receive information such as packets, user data, or control information associated with various information channels (e.g., control channels, data channels, and information related to group indications of spatially neighboring UEs, etc.). The information may be delivered to other components of the device 805. The receiver 810 may be a reference Fig.11 Examples of aspects of the transceiver 1120 are described.

[0154] The actions performed by the communication manager 815 as described herein may be implemented to achieve one or more potential advantages. One implementation may allow the base station 105 to reduce the overhead for managing the beamforming configuration of the neighboring UEs 115. By receiving the group proximity message from the UE 115, the base station 105 may perform efficient signaling by indicating the beamforming configuration of the group of UEs 115 rather than indicating the beamforming configuration of each UE 115 individually. For example, the UEs 115 may be close enough that the base station 105 is able to frequency-division multiplex the UEs 115 on the same beam. The base station 105 may then perform only one beam update and, in some cases, send beam update information for a single UE 115. In addition, the base station 105 may configure a subset of the UEs 115 in the group, and in some cases, a single UE 115, for beam measurement and reporting. This may provide measurement information of the same granularity or approximately the same granularity, with a significant reduction in the overhead of signaling.
