Technical Field

[0003] The following relates to wireless communications, and more particularly, the following relates to managing full-duplex communications. Background Art

[0004] Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, etc. These systems may have the ability to 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 (e.g., long term evolution (LTE) systems, improved LTE (LTE-A) systems, or LTE-A Pro systems) and fifth generation (5G) systems (which may be referred to as new radio (NR) systems). These systems may employ technologies such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal 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 one or more base stations or one or more network access nodes, each base station or network access node simultaneously supporting communication for multiple communication devices (which may also be referred to as user equipment (UE)).

[0108] A wireless communication system may support access links (e.g., Uu links) and sidelinks (e.g., PC5 links) for communication between wireless devices. For example, a UE (which may be an example of a vehicle supporting vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, device-to-device (D2D) communication, etc.) may select different directional beams for sidelink communication with other UEs. In some wireless communication systems (such as V2X systems), one or more wireless devices may have the ability to perform full-duplex communication to communicate on the sidelink. In such a case, one or more wireless devices may have the ability to perform simultaneous transmission and reception with one or more different devices on various sidelink communication links. Therefore, when performing full-duplex communication, one or more wireless devices may be susceptible to self-interference.

[0109] For example, a wireless device may experience self-interference due to antenna array leakage (e.g., interference between elements of an antenna array) or the use of both a transmit antenna array and a receive antenna array (e.g., communication at the transmit array causes interference at the receive antenna array, and vice versa). In some cases, a wireless device may implement one or more techniques to manage this self-interference for full-duplex communication. However, a device that supports full-duplex communication may experience additional interference due to signal reflections from objects near the device (this may be referred to as signaling echo, clutter echo, clutter interference, or other similar terms, where the objects may similarly be referred to as clutter objects or other terms). More specifically, a first device may send a message to a second device in a certain direction (e.g., using a directional beam), and when using full-duplex communication, the sent signaling may be reflected back to the first device or otherwise detected at the first device, while another message is concurrently received (e.g., from a third device using another directional beam). As a result, the first device may experience interference from its own signaling, which is reflected by one or more objects. In some examples, interference may be based on the physical characteristics of one or more objects and the positional relationship between the objects and the wireless device. Furthermore, objects can be stationary, quasi-stationary, or moving relative to a wireless device, and objects can include buildings, vehicles, infrastructure, or other equipment, among other examples. Thus, in some cases, interference from nearby objects can vary over time and can also be based on the movement of a device that is simultaneously transmitting and receiving (e.g., transmitting at a time that at least partially overlaps with a time when the device is receiving). Furthermore, a wireless device can concurrently experience interference from one or more objects (e.g., can experience interference from one or more objects at a time or at overlapping times).

[0110] As described herein, to account for objects at different locations, a wireless device may report a parameter set that indicates the presence or absence of objects that may cause interference at a full-duplex device. A parameter set may refer to one or more parameters. For example, two or more wireless devices supporting full-duplex communication may exchange information about objects that affect communication performance at various locations. The information about the objects may then be used to determine one or more communication parameters (e.g., transmit and receive beams for use at a particular location) that take into account any detected objects causing interference. The communication parameters may be configured accordingly to achieve efficient communication in the presence of one or more objects at multiple locations (e.g., as previously reported by one or more devices).

[0111] In some aspects, one or more wireless devices may transmit (e.g., broadcast, unicast, multicast) a set of parameters indicating the presence or absence of nearby objects causing interference, and other wireless devices may use these parameters. For example, the parameters reported by a first wireless device (e.g., a UE) may include the location of the first wireless device and the locations of other wireless devices (e.g., other UEs) with which the first wireless device is communicating in full-duplex. The parameters may also include one or more beam directions corresponding to one or more directional beams used by the first wireless device to communicate with the other wireless devices. Additionally or alternatively, the parameters may include the main beam direction and the direction of a zero-interference beam at a transmit and / or receive antenna array used by the first wireless device to communicate with the other wireless devices. Here, the main beam direction information and the direction information for the zero-interference beam may indicate the directional beam used for communication (e.g., based on an analog beamforming codebook) and the direction of reflected signaling / interference (e.g., from the device's own transmission), respectively. For example, the direction information for the zero-interference beam may be identified based on the reduced size of the communication beam due to interference at the first wireless device (e.g., the amplitude of the communication beam has been zeroed or affected by destructive interference). In some examples, the parameters may also include speed information providing the speed and / or direction of each of the first wireless device and the other wireless devices (which may be based on signaling received from the other devices, measurements performed by the first wireless device, etc.). Thus, the first wireless device may report various parameters indicative of its current communication conditions and parameters, which in turn may be used to identify the location of each of one or more objects that may cause reflection-type interference (e.g., interference from the device's own transmissions) at the full-duplex device. This information may then be used to configure, modify, or adjust communication parameters (such as beam direction or other parameters) when communicating in an area corresponding to or near the one or more objects.

[0112] As further described herein, a receiving device such as an RSU can provide information related to an object detected at a certain location, where the information can be based on composite information collected from one or more other wireless devices. For example, one or more wireless devices within the coverage area of ​​the RSU can send a set of parameters to the RSU, including but not limited to location information, directional beam information, main beam information, information for a zero-interference beam, and / or speed information corresponding to full-duplex communication performed by each wireless device. In some examples, the RSU can collect information from one or more wireless devices and estimate the location of the object causing the reflected interference. In addition, the RSU can estimate communication parameters that take into account the detected object. Thus, the RSU can send (e.g., broadcast, unicast, multicast) information to the wireless devices within its coverage area. Additionally or alternatively, the RSU can send information based on a configuration received from a specific wireless device.

[0113] Aspects of the present disclosure are first described in the context of a wireless communication system. Additionally, aspects of the present disclosure are illustrated by additional wireless communication systems and example process flow diagrams. Aspects of the present disclosure are further illustrated by, and described with reference to, apparatus diagrams, system diagrams, and flow diagrams relating to cooperative full-duplex techniques for sidelink communications.

[0114] Figure 1 An example of a wireless communication system 100 supporting a cooperative full-duplex technique for sidelink communications according to one or more aspects of the present disclosure is shown. The 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, the 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, 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, or any combination thereof.

[0115] Base stations 105 may be dispersed throughout a geographic area to form wireless communication system 100 and may be devices of varying forms or capabilities. Base stations 105 and UEs 115 may communicate wirelessly via one or more communication links 125. Each base station 105 may provide a coverage area 110 over which UEs 115 and base stations 105 may establish one or more communication links 125. Coverage areas 110 may be examples of geographic areas over which base stations 105 and UEs 115 may support transmission of signals according to one or more radio access technologies.

[0116] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary, mobile, or both at different times. The UEs 115 may be devices of different forms or with different capabilities. Figure 1 1. Some example UEs 115 are shown in FIG. 1. The UEs 115 described herein are capable of communicating with various types of devices, such as other UEs 115, base stations 105, or network devices (e.g., core network nodes, relays, integrated access and backhaul (IAB) nodes, or other network devices), such as Figure 1 shown.

[0117] The base stations 105 can communicate with the core network 130, or communicate with each other, or perform both of the above operations. For example, the base stations 105 can interface with the core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3 or other interfaces). The base stations 105 can communicate with each other directly (e.g., directly between base stations 105) on the backhaul links 120 (e.g., via X2, Xn or other interfaces), or communicate with each other indirectly (e.g., via the core network 130), or perform both of the above operations. In some examples, the backhaul links 120 can be or include one or more wireless links. The UE 115 can communicate with the core network 130 via the communication link 155.

[0118] One or more of the base stations 105 described herein may include or may be referred to by those skilled in the art as a base station transceiver, a radio base station, an access point, a radio transceiver, a Node B, an evolved Node B (eNB), a next generation Node B, or a Gigabit Node B (any of which may be referred to as a gNB), a Home Node B, a Home evolved Node B, or some other appropriate terminology.

[0119] UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other appropriate terminology, where a "device" may also be referred to as a unit, a station, a terminal, or a client, among other examples. UE 115 may also include or may be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, among other examples, which may be implemented in various items such as appliances, vehicles, meters, and other examples.

[0120] The UE 115 described herein is capable of communicating with various types of devices, such as other UEs 115, which may sometimes act as relays, as well as base stations 105 and network equipment, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, such as Figure 1 As shown. UE 115 described herein may be capable of communicating with RSU 160. In some cases, RSU 160 may be a wireless node used to connect road infrastructure and vehicles. In some cases, RSU 160 may perform many functions including, but not limited to, receiving data, combining data, synthesizing data, transmitting data, and configuring wireless resources.

[0121] The UE 115 and the base station 105 can communicate wirelessly with each other via one or more communication links 125 on one or more carriers. The term "carrier" can refer to a collection of radio frequency spectrum resources having a defined physical layer structure for supporting the communication link 125. For example, a carrier used for the communication link 125 can include a portion of a radio frequency spectrum band (e.g., a bandwidth part (BWP)) that operates 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 can carry acquisition signaling (e.g., synchronization signals, system information), control signaling to coordinate operation for the carrier, user data, or other signaling. The wireless communication system 100 can support communication with the UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, the UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used with both frequency division duplex (FDD) component carriers and time division duplex (TDD) component carriers.

[0122] The signal waveform transmitted on the carrier may be composed of multiple subcarriers (e.g., using multicarrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In systems employing MCM techniques, a resource element may comprise one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, or may be composed of one symbol period (e.g., the duration of one modulation symbol) and one 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 coding rate of the modulation scheme, or both). 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. Wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers may further increase the data rate or data integrity for communications with UE 115.

[0123] The basic time unit (which may be referred to as T s =1 / (Δf max ·N f ) seconds sampling period, where Δf max It can represent the maximum supported subcarrier spacing, and N fThe time intervals for the base station 105 or the UE 115 may be expressed as multiples of a maximum supported discrete Fourier transform (DFT) size. The time intervals of the communication resources may be organized according to radio frames, each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0124] Each frame may include a plurality of consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a number of 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 a number of symbol periods (e.g., depending on the length of a cyclic prefix added in front of each symbol period). In some wireless communication systems 100, a time slot may be further divided into a plurality of mini-slots containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0125] A subframe, slot, mini-slot, or symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in the form of bursts of shortened TTIs (sTTIs)).

[0126] Physical channels may be multiplexed on a carrier according to various techniques. For example, physical control channels and physical data channels may be multiplexed on a downlink carrier using one or more of time division multiplexing (TDM), frequency division multiplexing (FDM), or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET)) for a physical control channel may be defined by a number of symbol periods and may extend across the system bandwidth of a carrier or a subset of the system bandwidth. One or more control regions (e.g., CORESETs) may be configured for a group of UEs 115. For example, one or more of the UEs 115 may monitor or search the control region for control information according to one or more search space sets, and each search space set may include one or more control channel candidates at one or more aggregation levels arranged in a cascaded manner. The aggregation level for the control channel candidates may refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with the coded information for a control information format having a given payload size. The search space sets may include a common search space set configured for transmitting control information to multiple UEs 115 and a UE-specific search space set for transmitting control information to a specific UE 115 .

[0127] In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)) that may provide access to different types of devices.

[0128] In some examples, base station 105 can be mobile and, therefore, provide communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies can overlap, but the different geographic coverage areas 110 can be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies can be supported by different base stations 105. The wireless communication system 100 can 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 for various geographic coverage areas 110.

[0129] The wireless communication system 100 can support synchronous or asynchronous operation. For synchronous operation, the base stations 105 can have similar frame timing, and transmissions from different base stations 105 can be approximately aligned in time. For asynchronous operation, the base stations 105 can have different frame timing, and in some examples, transmissions from different base stations 105 may not be aligned in time. The techniques described herein can be used for either synchronous or asynchronous operation.

[0130] Some UEs 115 (e.g., 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 base station 105 without human intervention. In some examples, M2M communication or MTC may include communications from devices that incorporate sensors or meters to measure or capture information and relay such information to a central server or application that utilizes the information or presents it to a human interacting with the application. Some UEs 115 may be designed to collect information or implement automated behavior of machines or other equipment. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, climate and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based service billing.

[0131] Some UEs 115 may be configured to employ a mode of operation that reduces power consumption, such as half-duplex communication (e.g., a mode that supports one-way communication via transmission or reception rather than simultaneous transmission and reception). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power conservation techniques for UE 115 include entering a power-saving deep sleep mode when not engaged in active communications, when operating over a limited bandwidth (e.g., according to narrowband communication), or a combination of these techniques. For example, some UEs 115 may be configured to operate using a narrowband protocol type that is associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs)) within a carrier, within a guard band of a carrier, or outside a carrier.

[0132] The wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, the wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. UE 115 can be designed to support ultra-reliable, low-latency or critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private communication or group communication and can be supported by one or more mission-critical services such as mission-critical push-to-talk (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData). Support for mission-critical functions can include prioritization of services, and mission-critical services can be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency can be used interchangeably in this article.

[0133] In some examples, UE 115 can communicate directly with other UEs 115 over a device-to-device (D2D) (e.g., sidelink) communication link 135 (e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UEs 115 utilizing D2D communication can be within the geographic coverage area 110 of the base station 105. Other UEs 115 in such a group can 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 examples, groups of UEs 115 communicating via D2D communication can utilize a one-to-many (1:M) system, in which each UE 115 transmits to each other UE 115 in the group. In some examples, the base station 105 facilitates the scheduling of resources for the D2D communication. In other cases, the D2D communication is performed between the UEs 115 without involving the base station 105.

[0134] In some systems, the D2D communication link 135 can be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, the vehicles can communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination thereof. The vehicles can signal information related to traffic conditions, signal scheduling, weather, safety, emergency situations, or any other information related to the V2X system. In some examples, the vehicles in the V2X system can communicate with roadside infrastructure (such as roadside units) or communicate with the network via one or more network nodes (e.g., base station 105) using vehicle-to-network (V2N) communication, or both.

[0135] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function unit (AMF)) that manages access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function unit (UPF)) that routes packets to or interconnects to an external network. The control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management for UEs 115 served by base stations 105 associated with the core network 130. User IP packets may be transmitted through the user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to the network operator IP service 150. Operator IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0136] Some of the network devices (e.g., base stations 105) may include subcomponents such as access network entities 140, which may be examples of access node controllers (ANCs). Each access network entity 140 may communicate with the UE 115 through one or more other access network transport entities 145 (which may be referred to as radio heads, smart radio heads, or transmit / receive points (TRPs)). 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 heads and ANCs) or consolidated into a single network device (e.g., base station 105).

[0137] The electromagnetic spectrum is typically subdivided into various categories, bands, channels, etc. based on frequency / wavelength. In 5G NR, two initial operating bands have been identified with the frequency range names FR1 (410 MHz - 7.125 GHz) and FR2 (24.25 GHz - 52.6 GHz). It should be understood that although a portion of FR1 is greater than 6 GHz, FR1 is often (interchangeably) referred to as the "sub-6 GHz" band in various documents and articles. A similar naming issue sometimes arises with respect to FR2, which is often (interchangeably) referred to as the "millimeter wave" band in documents and articles, although it is different from the extremely high frequency (EHF) band (30 GHz - 300 GHz), which is identified as the "millimeter wave" band by the International Telecommunication Union (ITU).

[0138] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands of these mid-band frequencies as the frequency range designation FR3 (7.125 GHz–24.25 GHz). Frequency bands falling within FR3 may inherit FR1 characteristics and / or FR2 characteristics, and thus may effectively extend the characteristics of FR1 and / or FR2 to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operation above 52.6 GHz. For example, three higher operating bands have been identified as the frequency range designations FR4a or FR4-1 (52.6 GHz–71 GHz), FR4 (52.6 GHz–114.25 GHz), and FR5 (114.25 GHz–300 GHz). Each of these higher frequency bands falls within the EHF band.

[0139] In view of the above, unless otherwise specified, it should be understood that if the term "sub-6 GHz" or the like is used herein, it can be broadly referred to as a frequency that can be less than 6 GHz, can be within FR1, or can include mid-band frequencies. In addition, unless otherwise specified, it should be understood that if the term "millimeter wave" or the like is used herein, it can be broadly referred to as a frequency that can include mid-band frequencies, can be within FR2, FR4, FR4-a or FR4-1 and / or FR5, or can be within the EHF band.

[0140] The wireless communication system 100 can operate using one or more frequency bands in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). The region from 300 MHz to 3 GHz can be referred to as the ultra-high frequency (UHF) region or the decimeter band because the wavelengths range from approximately one decimeter to one meter in length. UHF waves can be blocked or redirected by buildings and environmental features, but the waves can penetrate structures sufficiently for macro cells to provide service to UEs 115 located indoors. Transmissions using UHF waves can be associated with smaller antennas and shorter distances (e.g., less than 100 kilometers) compared to transmissions using the smaller frequencies and longer waves of the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0141] The wireless communication system 100 can utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 can employ license assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band (such as the 5 GHz industrial, scientific, and medical (ISM) band). When operating in an unlicensed radio frequency spectrum band, devices (such as base stations 105 and UEs 115) can employ carrier sensing for conflict detection and avoidance. In some examples, operations in the unlicensed band can be based on a carrier aggregation configuration in combination with component carriers operating in a licensed band (e.g., LAA). Operations in the unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.

[0142] The base station 105 or UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of the base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels (which may support MIMO operations or transmit or receive beamforming). For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, the antennas or antenna arrays associated with the base station 105 may be located at different geographical locations. The base station 105 may have an antenna array having a number of rows and columns of antenna ports that the base station 105 may use to support beamforming for communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals transmitted via the antenna ports.

[0143] The base station 105 or UE 115 can use MIMO communication to take advantage of multipath signal propagation and improve spectral efficiency by sending or receiving multiple signals via different spatial layers. Such a technique may be referred to as spatial multiplexing. For example, a transmitting device may send 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 for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) (where multiple spatial layers are sent to the same receiving device) and multi-user MIMO (MU-MIMO) (where multiple spatial layers are sent to multiple devices).

[0144] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting device or a receiving device (e.g., a base station 105, a UE 115) to form or direct an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array so that some signals propagating at a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals transmitted via antenna elements can include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to the signals carried via the antenna elements associated with the device. Adjustments associated with each of the antenna elements can be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to the antenna array of the transmitting device or the receiving device, or relative to some other orientation).

[0145] As part of the beamforming operation, the base station 105 or the UE 115 can use beam scanning techniques. For example, the base station 105 can use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with the UE 115. The base station 105 can transmit some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) multiple times in different directions. For example, the base station 105 can transmit signals according to different sets of beamforming weights associated with different transmission directions. The transmissions in different beam directions can be used (e.g., by a transmitting device (such as the base station 105) or by a receiving device (such as the UE 115)) to identify the beam direction for subsequent transmission or reception by the base station 105.

[0146] Base station 105 may transmit some signals (e.g., data signals associated with a particular receiving device (e.g., UE 115)) in a single beam direction (e.g., a direction associated with the receiving device). In some examples, the beam direction associated with transmissions along the single beam direction may be determined based on signals transmitted in one or more beam directions. For example, UE 115 may receive one or more of the signals transmitted by base station 105 in different directions and may report to base station 105 an indication of the signal received by UE 115 having the highest signal quality or otherwise acceptable signal quality.

[0147] In some examples, transmissions by a device (e.g., by a base station 105 or a UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (e.g., from the base station 105 to the UE 115). The UE 115 may report feedback indicating precoding weights used for one or more beam directions, and the feedback may correspond to a configured number of beams across the system bandwidth or one or more subbands. The base station 105 may send reference signals (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)) that may be precoded or not precoded. The UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel type codebook, a linear combination type codebook, a port selection type codebook). Although these techniques are described with reference to signals sent by base station 105 in one or more directions, UE 115 may employ similar techniques to send signals multiple times in different directions (e.g., to identify a beam direction for subsequent transmission or reception by UE 115) or to send signals in a single direction (e.g., to send data to a receiving device).

[0148] When receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from the base station 105, a receiving device (e.g., UE 115) can try multiple reception configurations (e.g., directional listening). For example, the receiving device can try multiple reception directions by receiving via different antenna subarrays, by processing the received signals according to different antenna subarrays, by receiving according to different sets of receive beamforming weights applied to the signals received at multiple antenna elements of the antenna array (e.g., different sets of directional listening weights), or by processing the received signals according to different sets of receive beamforming weights applied to the signals received at multiple antenna elements of the antenna array (any of the above operations can be referred to as "listening" according to different reception configurations or reception directions). In some examples, the receiving device can use a single reception configuration to receive along a single beam direction (e.g., when receiving data signals). A 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 otherwise acceptable signal quality based on listening according to multiple beam directions).

[0149] The wireless communication system 100 can be a packet-based network operating according to a layered protocol stack. In the user plane, communications at the bearer or packet data convergence protocol (PDCP) layer can be IP-based. The radio link control (RLC) layer can perform packet segmentation and reassembly for transmission on logical channels. The medium access control (MAC) layer can perform priority handling and multiplexing of logical channels to transport channels. The MAC layer can also use error detection technology, error correction technology, or both to support 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 an RRC connection (which supports radio bearers for user plane data) between the UE 115 and the base station 105 or the core network 130. At the physical layer, transport channels can be mapped to physical channels.

[0150] In various examples, a communication manager can be a component of a device or included in a device to support various full-duplex technologies, such as reporting parameters indicating the presence or absence of objects that may cause reflection-type interference. For example, the UE 115 can include the communication manager 101, or the RSU 160 can include the receiving device communication manager 102.

[0151] In some examples, the communication manager 101 may send a first message to a device (e.g., UE 115) on a first sidelink communication link, and the first message may be sent using a first directional beam. The communication manager 101 may also receive a second message from another device (e.g., UE 115) on a second sidelink communication link when sending concurrently, and the second message may be received using a second directional beam different from the first directional beam. In some examples, the communication manager 101 may determine a parameter set based on concurrently sending the first message and receiving the second message, and the parameter set indicates the presence or absence of one or more objects causing interference at the first device. In some aspects, the parameter set includes location information, or directional beam information, or antenna array information, or speed information, or any combination thereof. The communication manager 101 may broadcast a fourth message including an indication of the parameter set.

[0152] The communication manager 101 may also receive a first message from a device (e.g., UE 115), the first message including a first parameter set indicating the presence or absence of one or more objects causing interference at a first location of a second device. The communication manager 101 may receive a second message from another device (e.g., UE 115), the second message including a second parameter set indicating the presence or absence of one or more objects causing interference at a second location different from the first location of a third device. In some examples, the first parameter set and the second parameter set may each include position information, or directional beam information, or antenna array information, or speed information, or any combination thereof. The communication manager 101 may determine communication parameters (e.g., beam direction) based on the first parameter set and the second parameter set, and use the communication parameters to communicate with one or more devices on a sidelink communication link.

[0153] In some examples, communication manager 101 may also determine a first location of UE 115 and receive a message from RSU 160 that includes communication parameters indicating the presence or absence of one or more objects causing interference at the first location of UE 115. Communication manager 101 may determine one or more beam directions for communicating with at least a second device based on the communication parameters and a second location of the second device (e.g., another UE 115). In some examples, communication manager 101 may communicate with the second device on a sidelink communication link using a directional beam according to the one or more beam directions.

[0154] The receiving device communication manager 102 may receive a first message from a first device (e.g., a first UE 115), the first message including a first parameter set indicating the presence or absence of one or more objects causing interference at a first location of the first device. In some examples, the receiving device communication manager 102 may receive a second message from a second device (e.g., a second UE 115), the second message including a second parameter set indicating the presence or absence of one or more objects causing interference at a second location of the second device that is different from the first location. In some aspects, the first parameter set and the second parameter set may each include location information, or directional beam information, or antenna array information, or speed information, or any combination thereof. The receiving device communication manager 102 may determine communication parameters based on the first parameter set and the second parameter set, the communication parameters indicating at least one or more beam directions for communicating at the location based on the presence or absence of one or more objects at the first location and the second location. In some cases, the receiving device communication manager 102 may send a third message including an indication of the communication parameters to at least the first device, or the second device, or any combination thereof.

[0155] The wireless communication system 100 may support technology that enables a UE 115 to report a set of parameters used to communicate with other devices, wherein the set of parameters may provide an indication of one or more nearby objects that cause reflection interference when the UE 115 communicates using full-duplex operation. For example, a UE 115 may communicate with two additional UEs 115 over a sidelink communication link and using directional beams. The UE 115 may determine its current location (e.g., GPS coordinates, absolute location, area ID, etc.) and the corresponding location of the additional UEs 115. The UE 115 may also determine the direction of the directional beam used to send and receive messages from the other UEs 115 (where the beam direction may correspond to a beam index). In addition, the UE 115 may determine the direction of the main beam and any zero-interference beams of its transmit and receive antenna arrays (where the zero-interference beams may be caused by reflection interference as described herein), and the UE 115 may also determine its current speed and / or direction of movement. Using this information, UE 115 can broadcast parameters including location information, beam information, antenna array information, and speed information to other UEs 115, which can then use these parameters to identify the most efficient beam to use based on the objects causing interference at a particular location. In other words, the parameters reported by UE 115 can provide crowdsourced information about multiple different objects at a particular location, and the crowdsourced information can then be used to estimate the locations of other objects and to optimize directional communications with other UEs. In some examples, the parameters can be sent by multiple UEs 115 to RSU 160, and RSU 160 can accumulate the received information and broadcast or send estimated communication parameters (e.g., beam direction) to each UE 115 based on its respective location (e.g., based on an area ID). UE 115 that receives such parameters can use this information to set its initial beam for communicating with other UEs at a particular location (which can be further adjusted through an additional beam refinement process).

[0156] Figure 2A 、 2B, 2C, and 2D illustrate examples of wireless communication systems 200 (e.g., wireless communication system 200-a, wireless communication system 200-b, wireless communication system 200-c, and wireless communication system 200-d) that support cooperative full-duplex technology for sidelink communications according to one or more aspects of the present disclosure. In some examples, wireless communication system 200-a, wireless communication system 200-b, wireless communication device 200-c, and wireless communication device 200-d can implement aspects of wireless communication system 100. For example, wireless communication system 200-a, wireless communication system 200-b, wireless communication device 200-c, and wireless communication device 200-d can include one or more devices 205 (e.g., one or more wireless devices) in a wireless network, where device 205 can include, for example, UE 115. In some examples, device 205 can be an example of a vehicle or another device that supports wireless communication (e.g., via an access link, via a sidelink, or both). In some examples, wireless communication system 200-a, wireless communication system 200-b, wireless communication device 200-c, and wireless communication device 200-d may include two or more wireless devices that communicate on a sidelink communication link using full-duplex communication technology in the presence of clutter objects. Thus, the wireless devices described herein may include, but are not limited to, UEs, vehicle user equipment (V-UEs), vulnerable road users (VRUs), drones, satellites, MTC devices, IoT devices, relays, repeaters, and the like.

[0157] As an example, Figure 2A An example of a wireless communication system 200-a supporting cooperative full-duplex technology for sidelink communications according to one or more aspects of the present disclosure is shown. Figure 2AIn the embodiment of the present invention, the first device 205-a can perform full-duplex communication with the second device 205-b on the side link 235-a and with the third device 205-c on the side link 235-b. For example, the first device 205-a can use the first directional beam 210-a to send one or more messages to the second device 205-b on the side link 235-a. In addition, the first device 205-a can concurrently use the second directional beam 210-b to receive one or more messages from the third device 205-c on the other side link 235-b. As shown, the first directional beam 210-a can be an example of a transmit beam (e.g., generated by one or more antenna elements of the transmit antenna array 240 at the first device 205). The second directional beam 210-b can be an example of a receive beam (e.g., generated by one or more antenna elements of the receive antenna array 245 at the first device 205). Furthermore, it should be noted that each device may form respective transmit and receive beams in directions corresponding to one or more beam directions, which may be based on precoding vectors analogous to a beamforming codebook.

[0158] Devices 205 (e.g., first device 205-a, second device 205-b, and third device 205-c) can communicate with each other in the presence of one or more objects 215 (e.g., clutter objects). Because at least first device 205-a can support full-duplex communication, when communicating using full-duplex communication, object 215 can be a source of interference (e.g., echo or reflection interference) at first device 205-a. In particular, and as described with respect to Figure 3 As described in further detail, the transmission of the first device 205-a can be reflected from the first object 215-a and detected at the receiving antenna array of the first device 205-a (e.g., when the first device concurrently receives from the third device 205-c). Such interference may affect the communication performance and / or signal quality at the first device 205-a. In some examples, the objects (e.g., the first object 215-a, the second object 215-b and / or the third object 215-c) can be stationary or moving. In addition or alternatively, the object 215 can be specific to a certain area 220 (e.g., area 220-a) or region. Although the area 220 is shown as a circle, the area 220 can have different shapes, including rectangles, hexagons, etc. In addition, the area 220 can correspond to an area that can be identified by an area ID. The area 220 can have different sizes or configurations, and the examples provided herein are provided for illustrative purposes and should not be considered limiting.

[0159] In some examples, one or more of the devices 205 can move relative to each other and / or relative to one or more objects 215. As an example, the first device 205-a can be mobile and can move in a certain direction and at a certain speed, as shown by arrow 225-a. Similarly, the second device 205-b can also be mobile, but in a different direction and / or at a different speed than the first device 205-a, for example, as shown by arrow 225-b. Alternatively, the third device 205-c can be stationary. In some examples, the first device 205-a can use signaling (e.g., safety messages) from other devices 205 to determine velocity information of the respective device 205, including speed and direction. In other cases, the first device 205-a can measure the speed and / or direction of the other devices 205.

[0160] The first device 205-a can also communicate with other devices using full-duplex communication. For example, the first device 205-a can communicate with other devices 205 (such as the fourth device 205-d) in different directions (e.g., using corresponding directional beams 210). Similarly, the fourth device 205-d can move in the same direction as the first device 205-a, but can have a different speed, as shown by arrow 225-c. Each device 205 of the wireless communication system 200-a can be located at a different location. For example, the first device 205-a can be located at a first location, the second device 205-b can be located at a second location different from the first location, and the third device 205-c can be located at a third location different from the first and second locations. Similarly, one or more objects 215 in the area 220 can be located at corresponding locations. Each location can correspond to an absolute location, a set of GPS coordinates, an area ID, etc. Additionally, devices may be located in and move about in different planes, where, for example, first device 205-a may be a vehicle traveling on a road or highway, and second device 205-b may be another vehicle traveling on an overpass or bridge that is located on a different plane (e.g., above) than first device 205-a. Thus, one or more of objects 215 (such as object 215-a or 215-c) may correspond to at least some portion of infrastructure that may reflect transmissions from device 205.

[0161] In another example, Figure 2B Devices 205 (e.g., device 205-e, device 205-f, device 205-g, device 205-h) may be shown, each of which may perform full-duplex communication (e.g., using directional beams 210) on a sidelink communication link. Each device may be an example of a vehicle, and one or more of the devices 205 may communicate with an RSU 230, which may be a reference Figure 12. In this example, an RSU 160 is described. In such a case, device 205-e can communicate with other devices on a sidelink using full-duplex communication (e.g., using directional beams 210-c and 210-d), and device 205-f can communicate with the same or other devices 205 on a sidelink using full-duplex communication (e.g., using directional beams 210-e and 210-f). Here, full-duplex communication can be performed in the presence of one or more objects 215 (e.g., objects 215-c and 215-e) located within area 220-b. In addition, each device 205 can exchange messaging with RSU 230.

[0162] Additionally or alternatively, as Figure 2C As shown, device 205-i can perform full-duplex communication on a sidelink with other devices, which may include a vehicle 245 (e.g., an unmanned aerial vehicle, a drone, an airplane, etc.) or a satellite 240, to name a few examples. Thus, device 205-i, aircraft 245, and satellite 240 can move perpendicular to each other. Device 205-i can communicate with other devices (e.g., vehicle 245 and / or satellite 240) using directional beams 210-g and 210-h. In addition, one or more objects 215 (e.g., objects 215-f and 215-g) can generate interference (e.g., reflected interference) at device 205-i based on full-duplex communication. Based on the altitude of vehicle 245 and / or satellite 240, objects can also be located above device 205-i within area 220-c. For example, object 215-f can be an example of a building or other infrastructure above device 205-i.

[0163] exist Figure 2DIn another example, wireless communication system 200-d may illustrate devices 205 that can communicate with each other using full-duplex communication, where one or more of devices 205 may include a VRU. As an example, first device 205-j may use directional beams 210-i and 210-j to communicate with other devices 205 within area 220-d (such as second device 205-k and bicycle 245). First device 205-j may be an example of a UE carried by a pedestrian (e.g., UE 115), while second device 205-k may be a vehicle (e.g., moving in a certain direction at a certain speed). Bicycle 245 may have an onboard device capable of performing wireless communication, or may be operated by a user with a UE. In any case, each device 205 and / or bicycle 245 may communicate in the presence of one or more objects 215 (e.g., objects 215-h, 215-i, 215-j) within area 220-d. These objects may cause reflection-type interference at one or more devices 205 communicating on the sidelink using full-duplex communication. It should be understood that the above examples are merely some scenarios, environments, or arrangements in which objects 215 may cause interference at full-duplex capable devices 205, and that other examples, scenarios, environments, and arrangements are possible but are not described herein for the sake of brevity.

[0164] As described herein, to account for objects 215 at different locations (e.g., within area 220), a device 205 (e.g., a wireless device) can report a set of parameters 230 indicating the presence or absence of objects 215 that may cause interference at a full-duplex device 205. For example, two or more devices 205 supporting full-duplex communication can exchange information about objects 215 that affect communication performance at various locations. The information about the objects 215 can then be used to determine one or more communication parameters (e.g., transmit and receive beams for use at a particular location) that account for any detected objects 215 that cause interference. The communication parameters can be configured accordingly to enable efficient communication in the presence of one or more objects 215 at multiple locations (e.g., as previously reported by one or more devices 205).

[0165] As an example, one or more devices 205 may transmit (e.g., broadcast, unicast, or multicast) a parameter set 230 indicating the presence or absence of a nearby object 215 causing interference, and the parameter set 230 may be used by other devices 205. For example, parameters 230-a, 230-b, 230-c, and 230-d reported by first device 205-a, device 205-e, device 205-i, and device 205-j, respectively, may include the location of the first device 205 and the locations of other devices 205 that exchange messages with the first device 205 using full-duplex communication. The location of the device 205 may be an absolute location, GPS coordinates, coordinates of a global navigation satellite system (GNSS), an area ID, etc. In some cases, the area ID may be mapped based on the absolute GPS coordinates.

[0166] The parameter set 230 may also include one or more beam directions corresponding to one or more directional beams 210 used by the first device 205 to communicate with other devices 205. In such a case, the beam direction may be represented by a beam index corresponding to each directional beam 210. For example, the first directional beam 210-a may have a first index, and the second directional beam 210-b may have a second index. The determined parameters may provide an indication of the index used by the device 205 for communicating using full-duplex communication.

[0167] Additionally or alternatively, the parameter set 230 may include a main beam direction and a direction of a zero interference beam at a transmit and / or receive antenna array used by the first wireless device for communicating with other wireless devices. Here, the main beam direction information and the direction information for the zero interference beam may indicate a directional beam used for communication (e.g., based on an analog beamforming codebook) and a direction of reflected signaling / interference (e.g., a transmission from the device itself), respectively. In some examples, the main beam direction information and the direction information for the zero interference beam may be represented as an index into a codebook of precoding vectors used by the device 205 for communicating with one or more other devices 205. Specifically, and with reference to Figure 2A , the transmit main beam direction and the direction for the zero interference beam can be represented as an index into the codebook of precoding vectors used by the first device 205-a for communication with the second device 205-b. Similarly, another index can be used to represent the receive main beam direction and the direction for the zero interference beam used by the first device 205-a for communication with the third device 205-c.

[0168] In some examples, the parameters may also include speed information providing a speed and / or direction of each of the first wireless device and the other wireless devices (which may be based on signaling received from the other devices, measurements performed by the first wireless device, etc.). As described herein, the speed information may include the speed and / or direction of the other devices 205, which may be determined or inferred based on a message from the device 205 or through measurements performed by one or more devices 205.

[0169] Thus, device 205 may report various parameters indicative of its current communication conditions and parameters, which in turn may be used to identify the location of each of one or more objects 215 that may be causing reflection-type interference (e.g., interference from the device's own transmissions) at full-duplex device 205. This information may then be used to configure, modify, or adjust communication parameters (such as beam direction or other parameters) when communicating in an area corresponding to or near the one or more objects.

[0170] In some examples, the device 205 may be configured to periodically send the parameter set 230. The period may be pre-configured, or the period may be dynamically configured. In some cases, the period may be determined by a base station (e.g., Figure 1 The configuration may be performed by the base station 105 described above, the RSU 230, or another controller or device. In some examples, the device 205 may be configured to transmit the parameter set 230 with a certain probability p, where the probability may be configured so as not to flood the channel if many wireless devices simultaneously transmit their parameter sets. In some cases, the probability may also be configured based on the priority of the wireless device, which may depend on the full-duplex capability of the device 205. As an example, the device 205 may have a relatively high capability (e.g., associated with a configuration processor of the device 205), and the configured probability may determine how often the device 205 reports the parameter set 230 to other devices. Additionally or alternatively, the configured probability may be based on the device's speed, which may also determine how often the device 205 reports the parameters. In yet another example, information about objects 215 in a certain area 220 may have been previously collected with a certain degree of accuracy, and the probability may be configured such that the device 205 reports the parameter set 230 less frequently, for example, based on accurate information about the objects 215 in the area 220.

[0171] In some examples, a first device 205 can determine communication parameters for a transmit or receive beam (e.g., a directional beam 210) based on a parameter set 230 received from one or more other devices 205. In such a case, the first device 205 can receive the parameter set 230 from another device 205 and use the parameter set 230 to determine the direction of a transmit and / or receive beam for the second device 205. The parameter set 230 can indicate the location, presence, or absence of an object 215 within a certain location and can be used to inform the starting direction of one or more directional beams 210. For example, a first device 205 at a first location can determine a beam direction for communicating with a second device 205 at a second location based at least on a transmit or receive beam direction used by a third wireless device at a third location (e.g., for communicating with a fourth device 205 at a fourth location). In this example, the first device 205 can also receive a beam direction used by the fifth device 205 at a fifth location to communicate with a sixth device 205 at a sixth location from a fifth device 205 at a fifth location. In some examples, the first device 205 may use parameter sets (eg, indicating object locations) from any number of other wireless devices 205 to determine a beam direction to use for communicating with the second device 205 .

[0172] As further described herein, the RSU 230 can provide information related to objects detected at a location to the device 205, where the information can be based on synthesized information collected from one or more other devices 205. In such cases, the RSU 230 can provide information to the device 205 based on synthesized information from multiple devices 205 in a geographic location (e.g., area 220). For example, one or more devices 205 can send a parameter set 230 to the RSU 230, the parameter set 230 including, but not limited to, location information, directional beam information, main beam information, information for a zero-interference beam, and / or speed information corresponding to full-duplex communications performed by each wireless device. That is, each device 205 can report its own location and the locations of other devices 205 with which it is performing full-duplex communications. In addition, each device 205 can report the transmit and receive main beam direction and the direction for a zero-interference beam, as well as the location of the device 205 with which it is performing full-duplex communications. The device 205 can also report the speed and / or direction of movement of the device with which it is performing full-duplex communications.

[0173] In some examples, the RSU can collect information from one or more wireless devices and estimate the location of objects causing reflective interference. Additionally, the RSU can estimate communication parameters that take into account the detected objects. Accordingly, the RSU can send (e.g., broadcast, unicast, multicast) information to wireless devices within its coverage area. Additionally or alternatively, the RSU can send information based on a configuration received from a specific wireless device.

[0174] In some examples, the RSU 230 may send (broadcast, unicast, multicast) the refined estimate based on the region ID. In such a case, there may be different sets or subsets of parameters for different locations (regions). As an example, a first set of parameters may correspond to a first region (e.g., region-ID1), while a second set of parameters may correspond to a second region (e.g., region-ID2), and so on. The first set of parameters may include the locations of the nodes (or their region IDs) and their corresponding transmit, receive, main beam directions, and / or directions for zero-interference beams, as represented by beam indices and precoding vector indices in an analog beamforming codebook. Thus, the device 205 receiving such information from the RSU 230 may identify the refined estimate and use the communication parameters based on the current location of the device 205.

[0175] Additionally or alternatively, the device 205 may configure the RSU 230 (e.g., via RRC signaling) to report refined communication parameters. For example, the RSU 230 may be configured to report parameters periodically, report parameters, or report parameters based on an event trigger. An event trigger may include, for example, the first time a device 205 enters a particular location, at which location information may be provided to the device 205 so that the device 205 is aware of any nearby objects 215 and possible beam directions for avoiding interference from these objects 215 (e.g., based on previously collected information). In another example, an event trigger may be based on increased network load or congestion (e.g., due to an increase in the number of devices 205 within the area 220), where the number and location of the interfering objects 215 may change dynamically or differ from the objects 215 previously detected / reported at the area 220. Other examples of event triggering are possible.

[0176] Figure 3An example of communication between devices in a system 300 supporting a cooperative full-duplex technique for sidelink communication according to one or more aspects of the present disclosure is shown. In some examples, communication between devices in the system 300 can implement aspects of the wireless communication system 100 or the wireless communication system 200. The system 300 may include two or more devices 305 (e.g., device 305-a, device 305-b, and device 305-c) that can perform full-duplex communication on a sidelink. In some cases, one or more objects 310 (e.g., objects 310-a and 310-b) may cause interference to one or more of the devices 305. In such a case, the device 305 may report a parameter set 345 identifying the object 310 causing the interference. For example, the parameter set 345 may include an index.

[0177] As shown, a first device 305-a can communicate with a second device 305-b over a communication link 315-a, and the first device 305-a can communicate with a third device 305-c over another communication link 315-b. Communication links 315-a and 315-b can be examples of sidelinks (e.g., where the first device 305-a, the second device 305-b, and the third device 305-c are all UEs 115). In other examples, communication link 315 can be an example of an access link or other channel for communication between devices 305.

[0178] When communicating with a second device 305-b and a third device 305-c, the first device can form a directional beam 320 for sending messages to and receiving messages from the other device 305. As an example, the first device 305-a can use a first antenna array (e.g., a transmit array, TX 325) to form one or more directional transmit beams (e.g., directional beam 320-a) in a first direction of the second device 305-b. The first direction of the directional beam 320-a can be based at least in part on minimizing path loss and maximizing SNR for communication between the first device 305-a and the second device 305-b. Similarly, the first device 305-a can concurrently use a second antenna array (e.g., a receive array, RX 330) to form one or more directional receive beams (e.g., including directional beam 320-b) in a second direction of the third device 305-c. The second direction of the directional beam 320 - b can be based at least in part on minimizing path loss and maximizing SNR for communications between the first device 305 - a and the third device 305 - c .

[0179] In some cases, when transmitting to a second device 305-b and receiving from a third device 305-c, transmissions 340-a and 340-b from the transmit array may propagate from the first device 305-a in one or more directions that are similar to or different from the first direction of the directional beam 320-a. Here, the transmissions 340-a and 340-b may reflect off one or more objects 310 located near or around the first device 305-a. That is, the transmission 340-a may interact with and reflect off of the first object 310-a (e.g., a clutter object). Similarly, another transmission 340-b may encounter and reflect off of the second object 310-b. The transmissions 340-a and / or 340-b may be directional in nature.

[0180] As shown, if one or more of transmissions 340-a and 340-b are reflected back to the receiver array of the first device 305-a, the signaling may cause interference with the reception of communications from the third device 305-c received on the directional beam 320-b. For example, transmission 340-a can be sent in a third direction so that it can be reflected from an object 310-a into the receiver of the first device 305-a, thereby causing interference. This interference can be identified at the first device 305-a by a zero-interference beam 350 at the receive antenna array of the first device 305-a. Thus, transmission 340-a can produce a first zero-interference beam 350-a, and transmission 340-b can produce a second zero-interference beam 350-b. However, each zero-interference beam 350 produced by a transmission can indicate one or more of the objects 310 near or surrounding the first device 305-a.

[0181] Thus, the first device 305-a may transmit (e.g., over a communication link 315) an indication of a parameter set 345 indicating the presence or absence of an object 310. For example, the first device 305-a may transmit (e.g., broadcast, unicast, multicast) a parameter set 345 indicating the presence or absence of the interference-causing object 310, and the parameter set 345 may be used by other devices (e.g., located in the same location and potentially similarly affected by the object 310). The parameter set 345 reported by the first device 305-a may include the location of the first device 305-a, the location of the second device 305-b, and the location of the third device 305-c. The parameter set 345 may also include one or more beam directions corresponding to one or more directional beams 320-a used by the first device 305-a to communicate with the other devices 305. Additionally, the parameter set 345 may include a main beam direction and a direction of a zero-interference beam at a transmit and / or receive antenna array used by the first wireless device to communicate with the other wireless devices. For example, the transmit main beam direction and the direction of the zero interference beam can be indicated by an index 390 of an analog beamforming codebook of precoding vectors that the first device 305-a has been using for communicating with the second device 305-b, where the main beam direction can correspond to the direction of the directional beam 320-a, and the direction of the zero interference beam can correspond to the direction of one or more zero interference beams at the transmit array (TX 325). Similarly, another index can be indicated for the receive main beam direction and the direction of the zero interference beam used by the first device 305-a for communicating with the third device 305-c, where the main beam direction can correspond to the direction of the directional beam 320-b, and the direction of the zero interference beam can correspond to the direction of one or more zero interference beams 350-a and / or 350-b at the receive antenna array (RX 330).

[0182] In some examples, the parameter set 345 may also include speed information that provides the speed and / or direction of the first device 305-a and the speed and / or direction of each of the second device 305-b and the third device 305-c (which may be based on signaling received from other devices, measurements performed by the first device 305-a, etc.). Thus, the first device 305-a may report a parameter set 345 indicating its current communication conditions and parameters, which in turn may be used to identify the location of each of one or more objects 310 that potentially cause reflection-type interference (e.g., interference from the device's own transmissions) at a full-duplex device in the same or similar location. This information may then be used to configure, modify, or adjust communication parameters (such as beam direction or other parameters) when communicating in an area corresponding to or near the one or more objects. For example, another device 305 may receive the parameter set 345 from the first device 305-a and may determine its proximity to the first device 305-a when it reports the parameter set. Based on the proximity, the other device 305 can identify a beam direction to use for communication in the presence of the same object 310. In other examples, the other device 305 can receive communication parameters from the RSU based on the location of the device, and the device 305 can determine the beam direction to use based on the information received from the RSU.

[0183] Figure 4 An example of a process flow 400 in a system supporting cooperative full-duplex technology for sidelink communications according to one or more aspects of the present disclosure is shown. In some examples, the process flow 400 can implement aspects of the wireless communication systems 100 and 200. The process flow 400 can include a first device 405-a, a second device 405-b, a third device 405-c, and a fourth device 405-d, which can be as described herein with reference to Figure 1 2 and 3.
