[0001] This patent application claims the benefit of U.S. Patent Application No. 18 / 606,964, entitled “FULL-DUPLEXCOLLISION HANDLING AND BEAM PAIRING”, filed March 15, 2024, by ZHANG et al., which has been assigned to the assignee of this application and is expressly incorporated herein by reference. Technical Field

[0002] The following discussion pertains to wireless communications, including full-duplex collision handling and beam pairing. Background Technology

[0003] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, message sending and receiving, and broadcasting. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth-generation (4G) systems (such as Long Term Evolution (LTE) systems, LTE-A Advanced (LTE-A) systems, or LTE-A Pro systems) and fifth-generation (5G) systems (which may be referred to as New Radio (NR) systems). These systems may employ technologies such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal FDMA (OFDMA), or Discrete Fourier Transform Extended Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations, each supporting wireless communication for communication devices, which may be referred to as User Equipment (UE). Summary of the Invention

[0004] The described technology relates to improved methods, systems, devices, and apparatuses supporting full-duplex collision handling and beam pairing. For example, the described technology enables a first wireless device (e.g., a UE, V2X device, full-duplex device) to manage collisions of control instructions requested by other wireless devices to transmit urgent data (e.g., data with a priority higher than a priority threshold), and to manage beam configuration based on the control instructions. The first wireless device can receive a first control instruction from a second wireless device and a second control instruction from a third wireless device. The first and second control instructions can be associated with corresponding parameters configured for (e.g., uniquely configured for, specific to) each wireless device. The first wireless device can send one or more feedback messages to the second and third wireless devices based on determining the corresponding parameters associated with the first and second control instructions. The first wireless device can also adjust one or more parameters associated with the full-duplex beam configuration based on the received control instructions. Such technologies can reduce latency associated with sidelink communication, improve the reliability of full-duplex and other communications, and utilize communication resources in wireless communication systems more efficiently.

[0059] In some wireless communication systems, wireless communication devices (e.g., network entities, user equipment (UEs), sidelink devices, vehicular (V2X) devices, repeaters, or other devices capable of wireless communication) can be configured to support full-duplex communication designs (e.g., single-frequency full-duplex (SFFD), sub-band full-duplex (SBFD)). Full-duplex communication enables wireless communication devices to simultaneously transmit and receive wireless signals. In some cases, a centralized controller (e.g., a network entity, a central unit (CU)) can manage transmit and receive scheduling in a full-duplex scenario. However, in some scenarios (e.g., in cellular V2X deployments), a centralized controller may not be available to coordinate transmit and receive scheduling. Therefore, a first wireless device (e.g., a full-duplex device, UE, sidelink device, V2X device) can manage full-duplex transmit and receive communication between itself and a second wireless device.

[0060] In some cases, a second wireless device may have relatively urgent data messages (e.g., high priority, priority level above a priority threshold, or associated with a priority higher than another message) to send to a first wireless device, and may accordingly send control indication messages (e.g., via a sidelink channel) that include requests to send urgent data to the first wireless device. However, the first wireless device may receive multiple control indications from different wireless devices simultaneously or within the same time window (e.g., this could lead to conflicts between multiple urgent messages), and the first wireless device may not be able to distinguish between multiple control indication messages and prioritize the corresponding urgent messages accordingly. Furthermore, the full-duplex communication of the first wireless device may be associated with self-interference, and the first wireless device may not support mechanisms for mitigating self-interference based on receiving multiple control indications. Therefore, the wireless device may not support techniques for scheduling (e.g., prioritizing, coordinating) competing transmissions from other wireless devices or techniques for reducing self-interference associated with full-duplex communication.

[0061] According to one or more aspects of this disclosure, a wireless communication system can support techniques that enable a first wireless device to handle (e.g., manage) conflicts between multiple control indication messages received from other wireless devices. Furthermore, the aspects described herein can be used to manage full-duplex beampair configurations based on received control indication messages. In some examples, each wireless device can be configured (e.g., by a network entity or CU) with corresponding control indication parameters (e.g., device-specific parameters) for transmitting control indication messages. Control indication parameters can be associated with signal type, sequence configuration, reference signal configuration, waveform type, and frequency resources, etc. Therefore, a wireless device can be able to distinguish conflicting control indication messages (e.g., differentiate, identify differences between them) by associating a given control indication message with a specific wireless device based on corresponding control indication parameters. Each wireless device can also be configured (e.g., via control indication messages) to transmit a priority indication, which can be used (e.g., by a receiving device) to prioritize various communications according to various signaling mechanisms. Additionally or alternatively, one or more techniques described herein can be used to implement beam management techniques (e.g., for self-interference mitigation) based on received control indication messages. For example, a wireless device may use a first beam configuration (e.g., a relatively wide beam) to monitor control indication messages and may control (e.g., adjust, modify, update) the first beam configuration in response to receiving a control indication message.

[0062] By applying the techniques described herein, wireless communication devices can support enhanced methods for managing various conflict scenarios (e.g., sidelink conflicts in URLLC and other emergency messages) and mitigating self-interference. For example, by supporting device-specific control indication parameters, wireless devices can independently schedule communications (e.g., full-duplex communication) with reduced network (e.g., network entities, CU) involvement, which can reduce latency and increase data rates. Furthermore, by managing beam configuration based on received control indication messages, wireless devices can autonomously reduce self-interference associated with full-duplex communication, thereby supporting increased communication reliability and improving the utilization of communication resources.

These aspects are further illustrated and described by reference to network architectures, process flows, apparatus diagrams, system diagrams, and flowcharts relating to full-duplex collision handling and beam pairing.

In various examples, network entity 105 may be referred to as a network element, mobility element, radio access network (RAN) node, or network equipment, etc. In some examples, network entity 105 and UE 115 may wirelessly communicate via communication link 125 (e.g., a radio frequency (RF) access link). For example, network entity 105 may support coverage area 110 (e.g., a geographical coverage area) within which UE 115 and network entity 105 may establish communication link 125. Coverage area 110 may be an example of a geographical area within which network entity 105 and UE 115 may support the transmission of signals according to one or more radio access technologies (RATs).

[0066] UE 115 can be distributed throughout the coverage area 110 of wireless communication system 100, and each UE 115 can be stationary or mobile, or stationary and mobile at different times. UE 115 can be devices in different forms or with different capabilities. Figure 1 Some example UE 115s are shown below. Figure 1 As shown, the UE 115 described herein may be able to support communication with various types of devices in the wireless communication system 100 (e.g., other wireless communication devices, including the UE 115 or network entity 105).

[0067] As described herein, a node in the wireless communication system 100 (which may be referred to as a network node or wireless node) may be a network entity 105 (e.g., any network entity described herein), a UE 115 (e.g., any UE described herein), a network controller, apparatus, device, computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, a node may be UE 115. As another example, a node may be network entity 105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be UE 115, the second node may be network entity 105, and the third node may be UE 115. In another aspect of this example, the first node may be UE 115, the second node may be network entity 105, and the third node may be network entity 105. In other aspects of this example, the first node, the second node, and the third node may be different from these examples. Similarly, references to UE 115, network entity 105, device, equipment, computing system, etc., may include disclosures of UE 115, network entity 105, device, equipment, computing system, etc., as nodes. For example, a disclosure that UE 115 is configured to receive information from network entity 105 also discloses that a first node is configured to receive information from a second node.

[0068] In some examples, network entity 105 may communicate with core network 130, communicate with each other, or both. For example, network entity 105 may communicate with core network 130 via backhaul communication link 120 (e.g., according to S1, N2, N3, or other interface protocols). In some examples, network entity 105 may communicate with each other directly (e.g., directly between network entities 105) or indirectly (e.g., via core network 130) via backhaul communication link 120 (e.g., according to X2, Xn, or other interface protocols). In some examples, network entity 105 may communicate with each other via midhaul communication link 162 (e.g., according to midhaul interface protocol) or fronthaul communication link 168 (e.g., according to fronthaul interface protocol) or any combination thereof. The backhaul communication link 120, midhaul communication link 162, or fronthaul communication link 168 may be one or more wired links (e.g., electrical links, fiber optic links) or one or more wireless links (e.g., radio links, wireless optical links), etc., or various combinations thereof, or may include one or more wired links (e.g., electrical links, fiber optic links) or one or more wireless links (e.g., radio links, wireless optical links), etc., or various combinations thereof. UE 115 may communicate with the core network 130 via communication link 155.

[0069] One or more network entities or network equipment in network entity 105 described herein may include or be referred to as base station 140 (e.g., transceiver base station, radio base station, NR base station, access point, radio transceiver, node B, eNodeB (eNB), next-generation node B or gigabit node B (any of which may be referred to as gNB), 5G NB, next-generation eNB (ng-eNB), home node B, home evolution node B, or other suitable terms). In some examples, network entity 105 (e.g., base station 140) may be implemented in an aggregated (e.g., monolithic, standalone) base station architecture that may be configured to utilize a protocol stack that is physically or logically integrated within a single network entity (e.g., network entity 105 or a single RAN node, such as base station 140).

[0070] In some examples, network entity 105 may be implemented in a decomposed architecture (e.g., a decomposed base station architecture, a decomposed RAN architecture) that can be configured to utilize protocol stacks physically or logically distributed across multiple network entities (e.g., network entity 105) such as an Integrated Access and Backhaul (IAB) network, an Open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a Virtualized RAN (vRAN) (e.g., a Cloud RAN (C-RAN)). For example, network entity 105 may include one or more of the following: a CU (such as CU 160), a Distributed Unit (DU) such as DU 165, a Radio Unit (RU) such as RU 170, a RAN Intelligent Controller (RIC) such as RIC 175 (e.g., a near real-time RIC (near RT RIC), a non-real-time RIC (non-RT RIC)), a Service Management and Orchestration (SMO) system such as SMO system 180, or any combination thereof. RU 170 may also be referred to as a radio headend, intelligent radio headend, remote radio headend (RRH), remote radio unit (RRU), or transmit / receive point (TRP). One or more components of network entity 105 in a decomposed RAN architecture may be co-located, or one or more components of network entity 105 may be located in distributed locations (e.g., separate physical locations). In some examples, one or more network entities in network entity 105 of a decomposed RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0071] The functional splitting among CU 160, DU 165, and RU 170 is flexible and can support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, or any combination thereof) are performed at CU 160, DU 165, or RU 170. For example, a protocol stack functional splitting can be used between CU 160 and DU 165, allowing CU 160 to support one or more layers of the protocol stack, and DU 165 to support one or more different layers of the protocol stack. In some examples, CU 160 can host upper-layer protocol layer (e.g., Layer 3 (L3), Layer 2 (L2)) functionality and signaling (e.g., Radio Resource Control (RRC), Service Data Adaptation Protocol (SDAP), Packet Data Convergence Protocol (PDCP)). CU 160 (e.g., one or more CUs) may connect to DU 165 (e.g., one or more DUs) or RU 170 (e.g., one or more RUs) or some combination thereof, and DU 165, RU 170, or both may host lower protocol layers, such as Layer 1 (L1) (e.g., Physical (PHY) layer) or L2 (e.g., Radio Link Control (RLC) layer, Medium Access Control (MAC) layer) functionality and signaling, and may each be at least partially controlled by CU 160. Additionally or alternatively, a protocol stack functional split may be employed between DU 165 and RU 170, such that DU 165 may support one or more layers of the protocol stack, and RU 170 may support one or more different layers of the protocol stack. DU 165 may (e.g., via one or more different RUs, such as RU 170) support one or more different cells. In some cases, functional decomposition between CU 160 and DU 165, or between DU 165 and RU 170, can be performed within the protocol layer (e.g., some functions of the protocol layer can be performed by one of CU 160, DU 165, or RU 170, while other functions of the protocol layer can be performed by a different one of CU 160, DU 165, or RU 170). CU 160 can be further functionally decomposed into CU control plane (CU-CP) functions and CU user plane (CU-UP) functions. CU 160 can be connected to DU 165 via midhaul communication link 162 (e.g., F1, F1-c, F1-u), and DU 165 can be connected to RU 170 via fronthaul communication link 168 (e.g., open fronthaul (FH) interface). In some examples, the midhaul communication link 162 or the fronthaul communication link 168 may be implemented based on the interfaces (e.g., channels) between the layers of the protocol stack, which are supported by corresponding network entities (e.g., one or more network entities in network entity 105) that communicate via such communication links.

[0072] In some wireless communication systems (e.g., wireless communication system 100), the infrastructure and spectrum resources for radio access can support wireless backhaul link capabilities to supplement wired backhaul connections, thereby providing an IAB network architecture (e.g., to core network 130). In some cases, in an IAB network, one or more network entities in network entity 105 (e.g., network entity 105 or IAB node 104) may be partially controlled by each other. IAB node 104 may be referred to as a donor entity or IAB donor. DU 165 or RU 170 may be partially controlled by CU 160 associated with network entity 105 or base station 140 (such as a donor network entity or donor base station). One or more donor entities (e.g., IAB donors) may communicate with one or more additional devices (e.g., IAB node 104) via supported access and backhaul links (e.g., backhaul communication link 120). IAB node 104 may include an IAB mobile terminal (IAB-MT) controlled (e.g., scheduled) by one or more DUs (e.g., DU 165) of a coupled IAB donor. The IAB-MT may be equipped with a separate set of antennas for relaying communication with UE 115, or may share the same antennas (e.g., RU 170) of IAB node 104 accessed via (e.g., referred to as a virtual IAB-MT (vIAB-MT)) DU 165. In some examples, IAB node 104 may include one or more DUs (e.g., DU 165) that support communication links with additional entities (e.g., IAB node 104, UE 115) within a relay chain or configuration (e.g., downstream) of the access network. In such cases, one or more components of the decomposed RAN architecture (e.g., IAB node 104, or components of IAB node 104) may be configured to operate according to the techniques described herein.

[0073] For example, the access network (AN) or RAN may include an access node (e.g., an IAB donor), communication between IAB node 104 and one or more UEs 115. The IAB donor may facilitate connectivity between the core network 130 and the AN (e.g., via a wired or wireless connection to the core network 130). That is, an IAB donor may refer to a RAN node having a wired or wireless connection to the core network 130. The IAB donor may include one or more of CU 160, DU 165, and RU 170, in which case CU 160 may communicate with the core network 130 via an interface (e.g., a backhaul link). The IAB donor and IAB node 104 may communicate via an F1 interface according to a protocol defining the signaling messages (e.g., the F1 AP protocol). Additionally or alternatively, CU 160 may communicate with core network 130 via an interface (which may be part of a backhaul link) and may communicate with other CUs (e.g., including CU 160 associated with an alternative IAB donor) via an Xn-C interface (which may be another part of a backhaul link).

[0074] IAB node 104 may refer to a RAN node that provides IAB functionality (e.g., access for UE 115, radio self-backhaul capability). DU 165 may act as a distributed scheduling node toward child nodes associated with IAB node 104, and IAB-MT may act as a scheduled node toward a parent node associated with IAB node 104. That is, an IAB donor may be referred to as a parent node communicating with one or more child nodes (e.g., an IAB donor may relay for UE transmissions via other IAB nodes 104). Additionally or alternatively, IAB node 104 may also be referred to as a parent or child node of other IAB nodes 104, depending on the AN's relay chain or configuration. Therefore, the IAB-MT entity of IAB node 104 can provide a Uu interface for the child IAB node (e.g., IAB node 104) to receive signaling from the parent IAB node (e.g., IAB node 104), and the DU interface (e.g., DU 165) can provide a Uu interface for the parent IAB node to send signaling notifications to the child IAB node or UE 115.

[0075] For example, IAB node 104 may be referred to as a parent node supporting communication to child IAB nodes, or as a child IAB node associated with an IAB donor, or both. An IAB donor may include a CU 160 having a wired or wireless connection to core network 130 (e.g., backhaul communication link 120) and may act as a parent node of IAB node 104. For example, an IAB donor's DU 165 may relay transmissions to UE 115 via IAB node 104, or may signal transmissions directly to UE 115, or both. An IAB donor's CU 160 may signal the establishment of a communication link to IAB node 104 via an F1 interface, and IAB node 104 may schedule transmissions (e.g., transmissions relayed from the IAB donor to UE 115) via one or more DUs (e.g., DU 165). In other words, data can be relayed to and from IAB node 104 via signaling through the NR Uu interface of the MT to IAB node 104 (e.g., other IAB nodes). Communication with IAB node 104 can be scheduled by the IAB donor or by DU 165 of IAB node 104.

[0076] When the techniques described herein are applied in the context of a decomposed RAN architecture, one or more components of the decomposed RAN architecture may be configured to support the tests described herein. For example, some operations described as being performed by UE 115 or network entity 105 (e.g., base station 140) may additionally or alternatively be performed by one or more components of the decomposed RAN architecture (e.g., components such as IAB node, DU 165, CU 160, RU 170, RIC 175, SMO system 180).

[0077] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or any other suitable term, wherein "device" may also be referred to as a cell, station, terminal, or client, etc. UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine-type communication (MTC) device, etc., which may be implemented in various objects such as appliances, vehicles, or meters.

[0078] The UE 115 described herein can communicate with various types of devices, such as the UE 115 which sometimes operates as a relay, as well as network entity 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc. Figure 1 As shown.

[0079] UE 115 and network entity 105 can wirelessly communicate with each other via communication link 125 (e.g., one or more access links) using resources associated with one or more carriers. The term "carrier" can refer to a set of RF spectrum resources having a defined PHY layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion of the RF spectrum band (e.g., a bandwidth portion (BWP)) operating according to one or more PHY layer channels for a given RAT (e.g., LTE, LTE-A, LTE-A Pro, NR). Each PHY layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating operation for the carrier, user data, or other signaling. Wireless communication system 100 can support communication with UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, UE 115 can be configured using multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used in conjunction with both frequency division duplex (FDD) component carriers and time division duplex (TDD) component carriers. Communication between network entity 105 and other devices can refer to communication between these devices and any part of network entity 105 (e.g., entity, sub-entity). For example, the terms “send,” “receive,” or “communicate” when referring to network entity 105 can refer to any part of the RAN’s network entity 105 (e.g., base station 140, CU 160, DU 165, RU 170) communicating with another device (e.g., directly or via one or more other network entities, such as one or more network entities in network entity 105)).

[0080] In some examples, such as in carrier aggregation configurations, a carrier may have acquisition signaling or control signaling that coordinates the operation of other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute RF Channel Number (EARFCN)) and may be identified according to a channel grating used for discovery by UE 115. A carrier may operate in standalone mode, in which case initial acquisition and connection can be performed by UE 115 via that carrier, or the carrier may operate in non-standalone mode, in which case different carriers (e.g., of the same or different RATs) are used to anchor the connection.

[0081] The communication link 125 of the wireless communication system 100 may include downlink transmission (e.g., forward link transmission) from network entity 105 to UE 115, uplink transmission (e.g., return link transmission) from UE 115 to network entity 105, or both, as well as other transmission configurations. The carrier may carry downlink communication or uplink communication (e.g., in FDD mode), or may be configured to carry both downlink and uplink communication (e.g., in TDD mode).

[0082] A carrier may be associated with a specific bandwidth of the RF spectrum, and in some examples, the carrier bandwidth may be referred to as the carrier or the “system bandwidth” of the wireless communication system 100. For example, the carrier bandwidth may be one of a set of bandwidths for a carrier for a specific RAT (e.g., 1.4 MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz, 20 MHz, 40 MHz, or 80 MHz). Devices of the wireless communication system 100 (e.g., network entity 105, UE 115, or both) may have hardware configurations that support communication using a specific carrier bandwidth, or may be configured to support communication using one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include network entity 105 or UE 115 that supports concurrent communication using carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate using a portion (e.g., subband, BWP) or all of the carrier bandwidth.

[0083] The signal waveform transmitted via a carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform extended OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element may refer to a resource of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, where the symbol period and subcarrier spacing may be 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 decoding rate of the modulation scheme, or both), such that a relatively high number of resource elements (e.g., in the transmission duration) and a relatively high modulation scheme order correspond to a relatively high communication rate. Wireless communication resources may refer to a combination of RF spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial resources may increase the data rate or data integrity used for communication with UE 115.

[0084] It can support one or more parameter sets for a carrier, and the parameter sets may include subcarrier spacing ( (and cyclic prefix). A carrier can be divided into one or more BWPs with the same or different sets of parameters. In some examples, multiple BWPs can be used to configure UE 115. In some examples, a single BWP of a carrier can be active at a given time, and communication for UE 115 can be constrained to one or more active BWPs.

[0085] The time interval for network entity 105 or UE 115 can be expressed as a multiple of a basic time unit, such as the sampling period. seconds, in response This can represent the supported subcarrier spacing, and This can represent the supported Discrete Fourier Transform (DFT) size. The time interval for organizing communication resources can be based on radio frames, each with a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0086] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may (e.g., in the time domain) be divided into subframes, and each subframe may also be 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 the cyclic prefix appended to each symbol period). In some wireless communication systems, such as wireless communication system 100, time slots may be further divided into multiple micro-time slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., The duration of a symbol period is associated with a (number) sampling period. The duration of a symbol period can depend on the subcarrier spacing or the operating frequency band.

[0087] A subframe, time slot, micro-time slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs)).

[0088] Depending on the technology, carriers can be used to multiplex physical channels for communication. One or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques can be used, for example, to multiplex physical control channels and physical data channels for signaling via a downlink carrier. The control region (e.g., control resource set (CORESET)) of the physical control channel can be defined by a set of symbol periods and can extend across the system bandwidth of the carrier or a subset of that bandwidth. One or more control regions (e.g., CORESET) can be configured for a set of UEs 115. For example, one or more UEs in UE 115 can monitor or search for control regions to obtain control information based on one or more search space sets, and each search space set can include one or more control channel candidates in one or more aggregation levels arranged in a concatenated manner. The aggregation level of control channel candidates can refer to the amount of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space set may include a common search space set configured to transmit control information to UE 115 (e.g., one or more UEs), or it may include a UE-specific search space set configured to transmit control information to UE 115 (e.g., a particular UE).

[0089] Network entity 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hotspots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity used (e.g., using a carrier) to communicate with network entity 105 and may be associated with an identifier used to distinguish adjacent cells (e.g., Physical Cell Identifier (PCID), Virtual Cell Identifier (VCID)). In some examples, a cell may also refer to a coverage area 110 or a portion of coverage area 110 (e.g., a sector) in which a logical communication entity operates. Depending on various factors such as the capabilities of network entity 105, the range of such cells may be from smaller areas (e.g., structures, subsets of structures) to larger areas. For example, a cell may be a building, a subset of buildings, or external space between or overlapping coverage areas 110, etc., or may include buildings, subsets of buildings, or external space between or overlapping coverage areas, etc.

[0090] Macro cells typically cover a relatively large geographic area (e.g., a radius of several kilometers) and allow unrestricted access to UE 115 that has a service subscription with a network provider supporting the macro cell. In contrast to macro cells, small cells may be associated with network entities 105 operating at lower power (e.g., base station 140 operating at lower power) and may operate using the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells may provide unrestricted access to UE 115 that has a service subscription with a network provider, or restricted access to UE 115 associated with a small cell (e.g., UE 115 in a closed subscriber group (CSG), or UE 115 associated with a user in a home or office). Network entity 105 may support one or more cells and may also use one or more component carriers to support communication via one or more cells.

[0091] In some examples, a carrier can support multiple cells and can be configured with different cells based on different protocol types that provide access for different types of devices (e.g., MTC, Narrowband IoT (NB-IoT), Enhanced Mobile Broadband (eMBB)).

[0092] In some examples, network entity 105 (e.g., base station 140, RU 170) may be mobile, and thus provide communication coverage to mobile coverage areas (such as coverage area 110). In some examples, coverage areas 110 associated with different technologies (e.g., different coverage areas) may overlap, but coverage areas 110 (e.g., different coverage areas) may be supported by the same network entity (e.g., network entity 105). In some other examples, overlapping coverage areas (such as coverage area 110) associated with different technologies may be supported by different network entities (e.g., network entity 105). The wireless communication system 100 may include, for example, a heterogeneous network in which different types of network entities 105 use the same or different RATs to support communication in coverage areas 110 (e.g., different coverage areas).

[0093] Some UE 115 devices (such as MTC or IoT devices) can be relatively low-cost or low-complexity devices and can provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC can refer to data communication technologies that allow devices to communicate with each other or with network entity 105 (e.g., base station 140) without human intervention. In some examples, M2M communication or MTC may include communication from devices with integrated sensors or instruments to measure or acquire information and relay such information to a central server or application that uses the information or presents it to people interacting with the application. Some UE 115 devices may be designed to collect information or enable automated behavior of machines or other devices. Examples of applications for 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 service charging.

[0094] Some UE 115s can be configured to operate in a power-saving mode, such as half-duplex communication (e.g., a mode that supports unidirectional communication via transmission or reception but does not involve concurrent transmission and reception). In some examples, half-duplex communication can be performed at a reduced peak rate. Other power-saving techniques for UE 115s include entering a power-saving deep sleep mode when not engaged in active communication, operating with limited bandwidth (e.g., according to narrowband communication), or a combination of these techniques. For example, some UE 115s can be configured to operate using a narrowband protocol type associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs)) within a carrier, within a carrier's guard band, or outside a carrier.

[0095] Wireless communication system 100 may be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, wireless communication system 100 may be configured to support ultra-reliable low-latency communication (URLLC). UE 115 may be designed to support ultra-reliable, low-latency, or critical functions. Ultra-reliable communication may include private or group communication and may be supported by one or more services, such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functions may include prioritizing services, and such services may be used for public safety or general business applications. The terms “ultra-reliable,” “low-latency,” and “ultra-reliable low-latency” are used interchangeably herein.

[0096] In some examples, UE 115 may be configured to support direct communication with other UEs (e.g., one or more UEs in UE 115) via a device-to-device (D2D) communication link (such as D2D communication link 135) (e.g., according to a peer-to-peer (P2P), D2D, or sidelink protocol). In some examples, one or more UEs 115 in a group performing D2D communication may be within the coverage area 110 of network entity 105 (e.g., base station 140, RU 170), which may support aspects of such D2D communication configured (e.g., scheduled by network entity 105). In some examples, one or more UEs 115 in such a group may be outside the coverage area 110 of network entity 105, or may otherwise be unable or not configured to receive transmissions from network entity 105. In some examples, a group of UEs 115 communicating via D2D communication can support a one-to-many (1:M) system, in which each UE 115 transmits to one or more UEs in the group. In some examples, network entity 105 can facilitate the scheduling of resources used for D2D communication. In some other examples, D2D communication can be performed between UEs 115 without involving network entity 105.

[0097] In some systems, the D2D communication link 135 may be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, vehicles may communicate using V2X communication, vehicle-to-vehicle (V2V) communication, or some combination of these communications. Vehicles may signal information related to traffic conditions, signaling, weather, safety, emergencies, or any other information relevant to the V2X system. In some examples, vehicles in a V2X system may communicate with roadside infrastructure (such as roadside units), or communicate with the network via one or more network nodes (e.g., network entity 105, base station 140, RU 170) using vehicle-to-network (V2N) communication, or both.

[0098] Core network 130 provides user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity (e.g., a Mobility Management Entity (MME), Access and Mobility Management Function (AMF)) for managing access and mobility, and at least one user plane entity (e.g., a Serving Gateway (S-GW), Packet Data Network (PDN) Gateway (P-GW), or User Plane Function (UPF)) for routing packets or interconnecting to external networks. The control plane entity manages non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by network entity 105 (e.g., base station 140) associated with core network 130. User IP packets can be delivered through the user plane entity, which provides IP address allocation and other functions. The user plane entity may connect to one or more network operator IP services 150. IP services 150 may include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0099] Wireless communication system 100 can operate using one or more frequency bands in the range of 300 MHz to 300 GHz. Generally, the area from 300 MHz to 3 GHz is referred to as the Ultra High Frequency (UHF) band or decimeter band because the wavelength range is approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features (which may be referred to as clusters), but these waves are sufficient to penetrate structures so that macrocells can provide service to UE 115 located indoors. Compared to communication using smaller frequencies and longer wavelengths in the High Frequency (HF) or Very High Frequency (VHF) portions of the spectrum below 300 MHz, communication using UHF waves can be associated with smaller antennas and shorter ranges (e.g., less than one hundred kilometers).

[0100] The wireless communication system 100 can also operate using the ultra-high frequency (SHF) region (also known as the centimeter band) in the range of 3 GHz to 30 GHz or the extremely high frequency (EHF) region (e.g., 30 GHz to 300 GHz) (also known as the millimeter band). In some examples, the wireless communication system 100 can support millimeter-wave (mmW) communication between the UE 115 and network entity 105 (e.g., base station 140, RU 170), and the EHF antennas of the corresponding devices can be smaller and more closely spaced than UHF antennas. In some examples, such techniques facilitate the use of antenna arrays within the device. However, compared to SHF or UHF transmissions, EHF transmissions may experience even greater attenuation and shorter range. The techniques disclosed herein can be adopted across transmissions using one or more different frequency regions, and the frequency band usage specified across these frequency regions may vary by country or regulatory authority.

[0101] Wireless communication system 100 may utilize both licensed and unlicensed RF spectrum bands. For example, wireless communication system 100 may employ licensed assisted access (LAA), LTE-Unlicensed (LTE-U) RAT, or NR technology using unlicensed frequency bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band). When operating with unlicensed RF spectrum, devices such as network entity 105 and UE 115 may employ carrier sensing for collision detection and avoidance. In some examples, operation using unlicensed frequency bands may be based on carrier aggregation configurations combined with component carriers operating with licensed frequency bands (e.g., LAA). Operation using unlicensed spectrum may include downlink transmission, uplink transmission, P2P transmission, or D2D transmission, etc.

[0102] Network entity 105 (e.g., base station 140, RU 170) or UE 115 may be equipped with multiple antennas that can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of network entity 105 or UE 115 may be located within one or more antenna arrays or antenna panels, which can support MIMO operation or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly (such as an antenna tower). In some examples, the antennas or antenna arrays associated with network entity 105 may be located at different geographical locations. Network entity 105 may include an antenna array having a collection of multiple rows and columns of antenna ports that network entity 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may include one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals transmitted via the antenna ports.

[0103] Network entity 105 or UE 115 can use MIMO communication to leverage multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. This technique is known as spatial multiplexing. The multiple signals can be transmitted, for example, by a transmitting device via different antennas or different combinations of antennas. Similarly, the multiple signals can be received by a receiving device via different antennas or different combinations of antennas. Each of the multiple signals can be referred to as a separate spatial stream and can carry information associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers can be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include: single-user MIMO (SU-MIMO), where multiple spatial layers are transmitted to the same receiving device; and multi-user MIMO (MU-MIMO), where multiple spatial layers are transmitted to multiple devices.

[0104] Beamforming (also known as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., network entity 105, UE 115) to shape or guide an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array such that some signals propagating along a specific orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to the signals transmitted via the antenna elements may include applying amplitude shifts, phase shifts, or both to the signals carried via the antenna elements associated with the device. The adjustments associated with each of these antenna elements may be defined by a beamforming weight set associated with a specific orientation (e.g., relative to the antenna array of the transmitting or receiving device or relative to some other orientation).

[0105] Network entity 105 or UE 115 may use beam scanning technology as part of beamforming operations. For example, network entity 105 (e.g., base station 140, RU 170) may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times by network entity 105 along different directions. For example, network entity 105 may transmit signals according to different beamforming weight sets associated with different transmission directions. Transmission along different beam directions may be used to identify (e.g., by a transmitting device (such as network entity 105) or by a receiving device (such as UE 115)) the beam direction for later transmission or reception by network entity 105.

[0106] Some signals (such as data signals associated with a specific receiving device) may be transmitted by a transmitting device (e.g., network entity 105 or UE 115) along a single beam direction (e.g., a direction associated with a receiving device such as another network entity 105 or UE 115). In some examples, the beam direction associated with transmission along a single beam direction may be determined based on the signals transmitted along one or more beam directions. For example, UE 115 may receive one or more signals transmitted by network entity 105 along different directions and may report to network entity 105 an indication of signals received by UE 115 with the highest signal quality or other acceptable signal quality.

[0107] In some examples, transmissions performed by a device (e.g., network entity 105 or UE 115) may be performed using multiple beam directions, and the device may use a combination of digital pre-decoding or beamforming to generate a combined beam for transmission (e.g., from network entity 105 to UE 115). UE 115 may report feedback indicating pre-decoding weights for one or more beam directions, and this feedback may correspond to a set of beams configured across the system bandwidth or one or more sub-bands. Network entity 105 may transmit reference signals (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)) that may or may not be pre-decoded. UE 115 may provide feedback for beam selection, which may be a pre-decoding matrix indicator (PMI) or codebook-based feedback (e.g., multi-panel codebook, linear combination codebook, port selection codebook). Although these techniques are described with reference to signals transmitted by network entity 105 (e.g., base station 140, RU 170) along one or more directions, UE 115 may use similar techniques to transmit signals multiple times along different directions (e.g., to identify the beam direction used by UE 115 for subsequent transmission or reception), or to transmit signals along a single direction (e.g., to transmit data to a receiving device).

[0108] A receiving device (e.g., UE 115) may perform reception operations according to multiple reception configurations (e.g., directional listening) when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from a transmitting device (e.g., network entity 105). For example, the receiving device may perform reception according to multiple reception directions by: receiving via different antenna subarrays; processing the received signal according to different antenna subarrays; receiving according to different sets of reception beamforming weights (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of the antenna array; or processing the received signal according to different sets of reception beamforming weights applied to signals received at multiple antenna elements of the antenna array. Any of these operations may be referred to as “listening” according to different reception configurations or reception directions. In some examples, the receiving device may use a single reception configuration to receive along a single beam direction (e.g., when a data signal is received). A single receiver configuration can be aligned along a beam direction determined based on listening according to different receiver configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or other acceptable signal quality based on listening according to multiple beam directions).

[0109] The wireless communication system 100 can be a packet-based network operating according to a layered protocol stack. In the user plane, communication at the bearer or PDCP layer can be IP-based. The RLC layer performs packet segmentation and reassembly for transmission via logical channels. The MAC layer performs priority processing and multiplexing of logical channels to transport channels. The MAC layer can also use error detection, error correction, or both to support retransmission to improve link efficiency. In the control plane, the RRC layer provides the establishment, configuration, and maintenance of RRC connections between the UE 115 and network entity 105 or core network 130 that support user plane data radio bearers. The PHY layer maps transport channels to physical channels.

[0110] UE 115 and network entity 105 can support data retransmission to increase the likelihood of successful data reception. Hybrid Automatic Repeat Request (HARQ) feedback is a technique used to increase the likelihood of correctly receiving data via communication links (e.g., communication link 125, D2D communication link 135). HARQ may include a combination of error detection (e.g., using Cyclic Redundancy Check (CRC)), forward error correction (FEC), and retransmission (e.g., Automatic Repeat Request (ARQ)). HARQ can improve throughput at the MAC layer under relatively poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, the device may support same-slot HARQ feedback, in which case the device can provide HARQ feedback in a specific time slot for data received via a previous symbol in that time slot. In some other examples, the device may provide HARQ feedback in subsequent time slots or according to a different time interval.

[0111] In some cases, the wireless communication system 100 can support NR duplex operation (e.g., full-duplex operation, SFFD, SBFD). Duplex operation can be associated with various deployment scenarios and evaluation methods, and can affect other operations (e.g., assuming coexistence in co-channel and adjacent channels). Specifically, duplex enhancement can be associated with identifying and evaluating potential enhancements to support duplex evolution for NR time-division duplex (TDD) in unpaired spectrum (e.g., dynamic and / or flexible TDD). In some cases, the wireless communication system 100 can support SBFD in scenarios based on TDD carriers or in-band carrier aggregation (CA). Such cases can be associated with the simultaneous transmission and reception of downlink and uplink signals on a subband basis and within the same time slot. For example, component carrier bandwidth can support one or more downlink subbands and one or more uplink subbands within the same time resource (e.g., the same time slot). Full-duplex communication (e.g., SBFD communication) can provide an increased uplink duty cycle, which can reduce latency. For example, full-duplex communication can enable communication of uplink signals in one or more uplink subbands within downlink or flexible time resources (e.g., time slots), or communication of downlink signals in one or more downlink subbands within uplink time resources. This can achieve latency savings and improved uplink coverage. In some cases, full-duplex communication can enhance system capacity, resource utilization, and spectrum efficiency, and (e.g., in a relatively robust manner according to uplink / downlink traffic) enable flexible and dynamic uplink / downlink resource adaptation.

[0112] According to one or more aspects of this disclosure, the wireless communication system 100 can support techniques that enable a first wireless device (e.g., UE 115, a V2X device, a V2V device) to manage conflicts between multiple control indication messages received from other wireless devices. Furthermore, the aspects described herein can be used to manage full-duplex beampair configurations based on received control indication messages. In some examples, each wireless communication device can be configured (e.g., by network entity 105) using corresponding control indication parameters (e.g., device-specific parameters) for transmitting control indication messages. Therefore, UE 115 or other devices can be able to distinguish conflicting control indication messages by associating a given control indication message with a specific wireless device based on the corresponding control indication parameters. Each wireless device can also be configured to transmit a priority indication, which can be used to prioritize various communications according to various signaling mechanisms. Additionally or alternatively, one or more techniques described herein can be used to implement beam management techniques (e.g., for self-interference mitigation) based on received control indication messages. For example, UE 115 can use a first beam configuration (e.g., a relatively wide beam) to monitor control indication messages and can control (e.g., adjust, modify, update) the first beam configuration in response to receiving a control indication message.

[0113] Figure 2 An example of a network architecture 200 (e.g., a decomposed base station architecture, a decomposed RAN architecture) supporting full-duplex collision handling and beamp-pairing according to one or more aspects of this disclosure is shown. Network architecture 200 may exemplify examples of one or more aspects for implementing wireless communication system 100. Network architecture 200 may include one or more CUs 160-a that can communicate directly with core network 130-a via backhaul communication link 120-a, or indirectly with core network 130-a via one or more decomposed network entities 105 (e.g., near-RT RIC 175-b via an E2 link or a non-RT RIC 175-a associated with SMO 180-a (e.g., an SMO framework) or both). CUs 160-a may communicate with one or more DUs 165-a via a corresponding midhaul communication link 162-a (e.g., an F1 interface). DUs 165-a may communicate with one or more RUs 170-a via a corresponding fronthaul communication link 168-a. RU 170-a may be associated with a corresponding coverage area 110-a and may communicate with UE 115-a via one or more communication links 125-a. In some implementations, UE 115-a may be served by multiple RU 170-a simultaneously.

[0114] Each network entity in network entity 105 of network architecture 200 (e.g., CU 160-a, DU 165-a, RU170-a, non-RT RIC 175-a, near-RT RIC 175-b, SMO 180-a, Open Cloud (O-Cloud) 205, Open eNB (O-eNB) 210) may include one or more interfaces or may be coupled to one or more interfaces configured to receive or transmit signals (e.g., data, information) via wired or wireless transmission media. Each network entity 105 or an associated processor (e.g., a controller) that provides instructions to the interfaces of network entity 105 may be configured to communicate with one or more network entities in other network entities 105 via transmission media. For example, these network entities 105 may include wired interfaces configured to receive signals or transmit signals to one or more network entities in other network entities 105 via wired transmission media. Additionally or alternatively, network entity 105 may include a wireless interface that may include a receiver, transmitter, or transceiver (e.g., an RF transceiver) configured to receive signals via a wireless transmission medium or to transmit signals to one or more other network entities in network entity 105, or both.

[0115] In some examples, the CU 160-a can host one or more higher-level control functions. Such control functions may include RRC, PDCP, SDAP, etc. Each control function can be implemented using an interface configured to communicate signaling with other control functions hosted by the CU 160-a. The CU 160-a can be configured to handle user plane functionalities (e.g., CU-UP), control plane functionalities (e.g., CU-CP), or combinations thereof. In some examples, the CU 160-a can be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP units can communicate bidirectionally with the CU-CP units via an interface such as an E1 interface. The CU 160-a can be implemented to communicate with the DU 165-a for network control and signaling purposes, as needed.

[0116] DU 165-a may correspond to a logic unit that includes one or more functions (e.g., base station functions, RAN functions) for controlling the operation of one or more RU 170-a. In some examples, DU 165-a may at least partially host one or more aspects of the RLC layer, MAC layer, and PHY layer (e.g., high PHY layers, such as modules for FEC encoding and decoding, scrambling, modulation and demodulation, etc.), depending at least in part on the functional partitioning, such as those defined by the 3rd Generation Partnership Project (3GPP). In some examples, DU 165-a may also host one or more low PHY layers. Each layer may be implemented using an interface configured to communicate with other layers hosted by DU 165-a or with control functions hosted by CU 160-a.

[0117] In some examples, lower-layer functionality may be implemented by one or more RU 170-a units. For example, an RU 170-a controlled by a DU 165-a may correspond to a logical node that hosts RF processing functions or low-PHY layer functions (e.g., performing Fast Fourier Transform (FFT), Inverse FFT (iFFT), digital beamforming, Physical Random Access Channel (PRACH) extraction and filtering, or both) based at least in part on functional decomposition (such as lower-layer functional decomposition). In such architectures, the RU 170-a may be implemented to handle over-the-air (OTA) communications with one or more UE 115-a units. In some specific implementations, the real-time and non-real-time aspects of control plane and user plane communications with the RU 170-a may be controlled by the corresponding DU 165-a unit. In some examples, such configurations enable the DU 165-a and CU 160-a to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.

[0118] The SMO 180-a can be configured to support RAN deployment and provisioning of both non-virtualized and virtualized network entities 105. For non-virtualized network entities 105, the SMO 180-a can be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via an operation and maintenance interface (e.g., the O1 interface). For virtualized network entities 105, the SMO 180-a can be configured to interact with a cloud computing platform (e.g., O-Cloud 205) via a cloud computing platform interface (e.g., the O2 interface) to perform network entity lifecycle management (e.g., to instantiate virtualized network entities 105). Such virtualized network entities 105 may include, but are not limited to, CU 160-a, DU 165-a, RU 170-a, and near-RT RIC 175-b. In some specific implementations, the SMO 180-a can communicate with components configured according to the 4G RAN (e.g., via the O1 interface). Additionally or alternatively, in some implementations, the SMO 180-a may communicate directly with one or more RU 170-a via the O1 interface. The SMO 180-a may also include a non-RT RIC 175-a configured to support the functionality of the SMO 180-a.

[0119] The non-RT RIC 175-a can be configured to include logical functions that enable non-real-time control and optimization of RAN elements and resources, artificial intelligence (AI) or machine learning (ML) workflows (including model training and updates, or policy-based guidance of applications / features in the near-RT RIC 175-b). The non-RT RIC 175-a can be coupled to or communicate with the near-RT RIC 175-b (e.g., via the A1 interface). The near-RT RIC 175-b can be configured to include logical functions that enable near real-time control and optimization of RAN elements and resources via data collection and actions on an interface (e.g., via the E2 interface) connecting one or more CU 160-a, one or more DU 165-a, or both, and the O-eNB 210 to the near-RT RIC 175-b.

[0120] In some examples, to generate AI / ML models to be deployed in a near-RT RIC 175-b, a non-RT RIC 175-a may receive parameters or external enrichment information from an external server. This information can be utilized by the near-RT RIC 175-b and can be received from non-network data sources or network functions at the SMO 180-a or non-RT RIC 175-a. In some examples, a non-RT RIC 175-a or near-RT RIC 175-b may be configured to tune RAN behavior or performance. For example, a non-RT RIC 175-a may monitor long-term trends and patterns in performance and employ AI or ML models to perform corrective actions via the SMO 180-a (e.g., via O1 reconfiguration) or via the generation of RAN management policies such as the A1 policy.

[0121] According to one or more aspects of this disclosure, network architecture 200 can support techniques that enable a first wireless device (e.g., UE115, DU 165, CU 160, RU 170) to manage conflicts between multiple control indication messages received from other wireless devices. The aspects described herein can also implement management of full-duplex beampair configurations based on received control indication messages. In some examples, each wireless device can be configured (e.g., by network entity 105, CU 160, etc.) using corresponding control indication parameters (e.g., device-specific parameters) for transmitting control indication messages. Wireless devices can distinguish conflicting control indication messages by associating a given control indication message with a specific wireless device based on corresponding control indication parameters. Each wireless device can also be configured (e.g., via control indication messages) to transmit a priority indication, which can be used (e.g., by a receiving device) to prioritize various communications according to various signaling mechanisms. One or more techniques described herein can also implement beam management techniques (e.g., for self-interference mitigation) based on received control indication messages. For example, a wireless device may use a first beam configuration (e.g., a relatively wide beam with a beamwidth above a beamwidth threshold) to monitor control indication messages and may control (e.g., adjust, modify, update) the first beam configuration in response to receiving a control indication message.

[0122] Figure 3 An example of a wireless communication system 300 supporting full-duplex collision handling and beam pairing according to one or more aspects of this disclosure is shown. The wireless communication system 300 can support sidelink communication (e.g., V2X communication) between various wireless communication devices (e.g., UE 115, vehicles). Additionally, the wireless communication system 300 can implement as referenced... Figure 1 and Figure 2The described aspects of the wireless communication system 100 and network architecture 200 may be implemented by or by the wireless communication system and the network architecture. For example, the wireless communication system 300 may include multiple UEs 115 (e.g., UE 115-a, UE 115-b, UE 115-c, UE 115-d), which may represent as referenced. Figure 1 and Figure 2 An example of the corresponding device described. Although Figure 3 The examples depict UE 115-a, UE 115-b, UE 115-c, UE 115-d, and UE 115-e as vehicle devices (e.g., V2X devices), but the techniques described herein can be similarly applied to any wireless communication device, such as other UEs, network devices (e.g., network entities 105, DU 165, RU 170, CU 160), or other wireless communication devices (e.g., including those mentioned in the references). Figure 1 and Figure 2 (as described).

[0123] In some cases, UE 115-a (e.g., a V2X device, a sidelink device, a gNB) can communicate with one or more other UE 115s via a corresponding communication link 310 (e.g., a sidelink channel). For example, UE 115-a can communicate with UE 115-b, UE 115-c, UE 115-d, and UE 115-e via communication links 310-a, 310-b, 310-c, and 310-d, respectively. UE 115-a can be configured for full-duplex communication and may include a full-duplex radio 305, enabling UE 115-a to transmit (e.g., output, transmit) a first communication signaling and receive (e.g., acquire, monitor) a second communication signaling within the same time resources (e.g., at the same time, simultaneously). Each of UE 115-b, UE 115-c, UE 115-d, and UE 115-e may support full-duplex communication (e.g., via their own full-duplex radio) or may support half-duplex communication. As described herein, the wireless communication system 300 may support techniques for managing communication conflicts (e.g., contention) and beam pairing in cellular V2X (C-V2X) applications (e.g., in the absence of a central controller).

[0124] In some cases, half-duplex design can be a constraint in C-V2X applications, especially when there is no centralized controller (e.g., gNB, CU, network entity 105) to coordinate transmit and receive scheduling. This problem can become more pronounced in mixed-service scenarios, where there may be a relatively large number of best-effort traffic and a relatively small number of urgent messages (e.g., URLLC data). For example, UE 115-a may be transmitting a relatively large amount of data traffic 315 (e.g., best-effort traffic) to UE 115-b, while simultaneously, UE 115-b (e.g., or another UE 115) may have an urgent message to transmit to UE 115-a. However, the arrival time of the urgent message from UE 115-b may not be known in advance, and UE 115-a may be continuously monitoring (e.g., using full-duplex radio 305) for incoming reception (e.g., even while transmitting data traffic 315) to receive the urgent message.

[0125] Additionally, UE 115-a may be equipped with a full-duplex radio 305 (e.g., SFFD radio, SBFD radio) and may be a device with full-duplex capability. Full-duplex communication may be associated with self-interference and may impose further constraints on UE 115-a. For example, the transmitted signal of UE 115-a may interfere with the incoming signal to be received by UE 115-a. Furthermore, self-interference may originate from other sources, such as signal leakage within the device (e.g., within internal components of UE 115-a), signal reflection, and / or clutter associated with the environment in which the wireless communication system 300 is operating. While UE 115-a is transmitting, UE 115-a may also use the full-duplex radio 305 to monitor control indications 320 (e.g., control indication signals, control indication messages) from another UE 115 (e.g., UE 115-c, UE 115-d). Control indication 320 may be an example of a message indicating a message transmission request (e.g., an emergency message request, a URLLC transmission request, or a request for emergency transmission to UE 115 that receives control indication 320).

[0126] In some cases, UE 115-a may be sending data service 315 (e.g., a relatively large volume of traffic) to UE 115-b. Simultaneously (e.g., or at least partially overlapping in time or within a time window), UE 115-c and UE 115-d (e.g., more than one UE 115) may both have urgent messages to transmit to UE 115-a. Therefore, UE 115-c may send control indication 320-a, and UE 115-d may send control indication 320-b. However, control indication 320-a and control indication 320-b may both arrive at UE 115-a simultaneously (e.g., detected by monitoring UE 115-a). That is, a conflict (e.g., contention) may exist between control indication 320-a and control indication 320-b, which could lead to a conflict between the transmission of first urgent data from UE 115-c and the transmission of second urgent data from UE 115-d to UE 115-a. Additionally, UE 115-a may not support a mechanism for distinguishing different control indications 320, nor a mechanism for prioritizing the corresponding transmission of emergency data from multiple requesting UE 115s.

[0127] According to one or more techniques described herein, UE 115-a may support techniques for determining (e.g., differentiating, distinguishing, identifying, detecting) the association between a given control indication 320 and a specific UE 115 based on one or more control indication parameters 330. For example, in order for UE 115-a to differentiate different control indications 320 (e.g., emergency data transmission requests) from different devices (e.g., UE 115-c and UE 115-d), network entity 105 (not shown) (e.g., gNB or CU 160) may configure each device of wireless communication system 300 with unique (e.g., device-specific) control indication parameters 330. That is, UE 115-c may be configured with a first set of one or more control indication parameters 330-a, and UE 115-d may be configured with a second set of one or more control indication parameters 330-b (e.g., where at least one parameter differs between control indication parameters 330-a and control indication parameters 330-b).

[0128] Therefore, UE 115-c can transmit control indication 320-a according to one or more control indication parameters 330-a in the first set, and UE 115-d can transmit control indication 320-b according to one or more control indication parameters 330-b in the second set. Control indication parameters 330 may include device-specific control signals (e.g., signal types), signal sequences, reference signals, waveforms, scrambling codes, other signaling parameters, or any combination thereof. In some examples, network entity 105 may additionally or alternatively configure device-specific frequency resources (e.g., specific resource elements (REs)) for each UE 115 for the transmission of control indication 320. Device-specific frequency resources (e.g., REs) may be orthogonal in the frequency domain, and thus conflicts between control indication 320-a and control indication 320-b for transmission to UE 115-a can be avoided. Using device-specific control indication parameters 330, UE 115-a can determine (e.g., identify, determine, or otherwise identify) which UE 115 has an emergency message request.

[0129] In some examples, UE 115-a may receive control indication 320-a and control indication 320-b within the same (e.g., at least partially overlapping) time resources, and both control indications 320 may indicate corresponding emergency message transmission requests from UE 115-c and UE 115-d. To determine which UE 115 (e.g., UE 115-c or UE 115-d) will transmit (e.g., be permitted to transmit) its emergency message first, a priority indication may be sent (e.g., transmitted) from UE 115-c and UE 115-d to UE 115-a. In some examples, the priority indication may be included in control signaling (e.g., control indication 320, request signaling, as an additional or optional value) to enable UE 115-a to determine the transmission order when conflicts arise among multiple control indications 320. For example, a priority indicator may include a priority index (e.g., 0, 1, or some other value), and UE115-a may determine the order in which emergency messages are sent based on the value of the priority index associated with UE 115. As a non-limiting example, UE 115-c may indicate priority 0, UE 115-d may indicate priority 1, and UE 115-a may determine that an emergency message from UE 115-c is sent before an emergency message from UE 115-d.

[0130] After transmission control instruction 320, UE 115-c and / or UE 115-d may not autonomously (e.g., automatically, automatically) send their emergency data messages because data transmissions may conflict (e.g., from two devices in this case), which could cause message reception failure at UE 115-a. Therefore, UE 115-a may send one or more feedback messages 325 (e.g., feedback signaling) to instruct (e.g., grant, command, permit) UE 115-c or UE 115-d to send their emergency data. UE 115-a's decision may be based on the appropriate priority indication in control instruction 320 (e.g., request signaling). As a non-limiting example, if a first priority indication from UE 115-c has a relatively higher priority than a second priority indication from UE 115-d (e.g., data from UE 115-c has a higher priority than data from UE 115-d), then UE 115-a may transmit a feedback message 325-a to UE 115-c that includes an acknowledgment (ACK) message. UE 115-a may also transmit a feedback message 325-b to UE 115-d that includes a negative acknowledgment (NACK) message, thereby allowing (e.g., permitting) UE 115-c to send urgent data to UE 115-a (e.g., before UE 115-d).

[0131] Additionally or alternatively, UE 115-a may transmit a feedback message 325 (e.g., in response to control indication 320) indicating (e.g., for UE 115-c and UE 115-d) the transmission order and the time resources (e.g., time slots) for the respective UE 115 to transmit its emergency data. For example, feedback message 325-a may indicate a first time slot for UE 115-c to transmit a first emergency data message, and feedback message 325-b may indicate a second time slot for UE 115-d to transmit a second emergency data message. UE 115-a may determine (e.g., decide) the time resources for the respective UE based on the priority indication in control indication 320 (e.g., request signaling). As a non-limiting example, if UE 115-c has a relatively higher priority than UE 115-d (e.g., data from UE 115-c has a higher priority than data from UE 115-d), then feedback message 325-a may instruct UE 115-c to send emergency data in a first time slot (e.g., time slot 0, the same time slot as feedback message 325-a and / or control indication 320-a), and feedback message 325-b may instruct UE 115-d to send emergency data in a second time slot (e.g., time slot 1, a subsequent time slot after the time slot including feedback message 325-b and / or control indication 320-b).

[0132] In some examples, feedback message 325 may indicate time resources for emergency data transmission based on one or more bits included in feedback message 325. For example, a first value of one or more bits (e.g., "00") may indicate that UE 115 (e.g., UE 115 receiving feedback message 325) will transmit emergency data in the same time slot that includes feedback message 325 and / or control indication 320-a. A second value of one or more bits (e.g., "01") may indicate that UE 115 will transmit emergency data in the subsequent time slot immediately following feedback message 325 (e.g., the next time slot). A third value of one or more bits (e.g., "10") may indicate that UE 115 will transmit emergency data in a second subsequent time slot after feedback message 325 (e.g., the time slot after the next time slot). A fourth value of one or more bits (e.g., "11") may indicate that UE 115 is not allowed to transmit emergency data (e.g., transmission by UE 115 is not allowed). For example, in an example where UE 115-c has a relatively higher priority than UE 115-d, UE 115-a can prioritize the urgent data of UE 115-c by sending a first value (e.g., "00") to UE 115-c via feedback message 325-a and a second value (e.g., "01") to UE 115-d via feedback message 325-b.

[0133] In some additional or alternative examples, feedback message 325 from UE 115-a may indicate the transmission order of UE 115-c and UE 115-d, as well as the time offset (e.g., backoff offset time) for the lower-priority UE 115 to transmit its urgent data. The decision on transmission order made by UE 115-a may be based on the priority indication included in control indication 320 (e.g., request signaling). As a non-limiting example, if UE 115-c has a relatively higher priority than UE 115-d, feedback message 325-a may instruct UE 115-c to transmit urgent data in a first timeslot (e.g., the same timeslot as feedback message 325-a and / or control indication 320-a, which may include an ACK message), and feedback message 325-b may instruct UE 115-d to transmit urgent data after the time offset (e.g., backoff offset). In some examples, the time offset may be associated with (or represented by) the number of symbols, time slots, milliseconds, or some other time resource indicated in feedback message 325.

[0134] In some examples, UE 115-a may receive one or more control indications 320 after another data transmission previously scheduled by another UE 115 (e.g., UE 115-e). For example, while UE 115-a is receiving control indication 320-a or control indication 320-b (e.g., other control signal requests), UE 115-a may have already scheduled a data transmission from UE 115-e in the same time slot. In such examples, if the data to be transmitted by UE 115-e has a higher priority than the data from UE 115-c and UE 115-d, UE 115-a may send a NACK message (e.g., or may send the bit value "11") via both feedback message 325-a and feedback message 325-b, indicating that the transmission will not be sent from UE 115-c or UE 115-d. If the data to be transmitted by UE 115-e has a lower priority than the data from UE 115-c and UE 115-d, UE 115-a can send a feedback message 325-c (e.g., a cancellation message, a quick cancellation indication) (e.g., a bit value "11") to UE 115-e, indicating cancellation of the scheduled transmission for UE 115-e. That is, the bit value of feedback message 325 (e.g., "11") can be interpreted as "no transmission" for UE 115-c and UE 115-d, and can be interpreted as cancellation of the existing scheduled data transmission for UE 115-e.

[0135] Figure 4 An example of a wireless communication system 400 supporting full-duplex collision handling and beam pairing according to one or more aspects of this disclosure is shown. The wireless communication system 400 can support sidelink communication (e.g., V2X communication) between various wireless communication devices (e.g., UEs, vehicles). Additionally, the wireless communication system 400 can implement as referenced... Figures 1 to 3 The described aspects of the wireless communication system 100, network architecture 200, and wireless communication system 300, or aspects implemented by these aspects. For example, the wireless communication system 400 may include multiple UEs 115 (e.g., UE 115-f and UE 115-g), which may represent, as referenced... Figures 1 to 3 An example of the corresponding device described. Although Figure 4 The examples depict UE 115-f and UE 115-g as vehicles (e.g., V2X devices), but the techniques described herein can be similarly applied to any wireless communication device, such as other UE devices or network devices (e.g., network entities 105, DU 165, RU 170, CU 160).

[0136] UE 115-f and UE 115-g can be configured for full-duplex operation. For example, UE 115-f can support beam configuration 405 for receiving (e.g., acquiring, monitoring, detecting) radio signaling and beam configuration 410 for transmitting (e.g., outputting, transmitting, delivering) radio signaling. In some examples, when UE 115-f is transmitting (e.g., transmitting message 415), UE 115-f can utilize full-duplex radios (e.g., full-duplex radio 305, SFFD radio, SBFD radio) to monitor control indications 420 (e.g., control indication 320, control indication signal) from UE 115-g indicating a request to send an emergency message (e.g., URLLC data) (e.g., UE 115-g may have an emergency message to send to UE 115-f).

[0137] UE 115-f may use a relatively narrow beam for beam configuration 410 (e.g., transmit beam, beam 1, transmit beam associated with the highest reference signal received power (RSRP) to UE 115-g), and UE 115-f may use a relatively wide beam for beam configuration 405 (e.g., omnidirectional or quasi-omnidirectional receive beam, receive beam 3) for receive control indication 420. Beam configuration 405 may also be associated with a relatively low signal-to-interference and noise ratio (SINR). In some examples, beam configuration 405 (e.g., transmit beam) and beam configuration 410 (e.g., omnidirectional / quasi-omnidirectional receive beam) for full-duplex communication may be impractical (e.g., beam configuration 410 may generate a relatively high level of self-interference at beam configuration 405). Therefore, UE 115-f can apply one or more of the techniques described herein to reduce self-interference and increase the reliability of full-duplex operation between UE 115-f and UE 115-g (e.g., by maintaining transmission from UE 115-f to UE 115-g while receiving emergency data services from UE 115-g in full-duplex mode).

[0138] In some examples, UE 115-f can monitor and receive control indication 420 via beam configuration 405. Based on (e.g., in response to) receiving control indication 420, UE 115-f can apply one or more techniques to determine one or more parameters 430 associated with beam configuration 405, beam configuration 410, or both, in order to manage beam pairing (e.g., beam selection). In some examples, UE 115-f can switch beam configuration 405 and beam configuration 410 (e.g., beam pair) such that the corresponding beam is associated with reduced self-interference (e.g., a viable beam pair where the selected beam may be different from the highest RSRP beam used for half-duplex operation). That is, UE 115-f can use beam configuration 405 (e.g., wide beam) to monitor control waveforms (e.g., control indication 420) and can then adjust beam configuration 405 (e.g., switch to narrow beam) in response to detecting an incoming waveform.

[0139] For example, based on previous beam management (e.g., a previous selection of a beam pair consisting of beams 1 and 3), updated beams (e.g., beams 4 and 5) can be paired for full-duplex operation at UE 115-a (e.g., by adjusting one or more parameters 430 associated with beam configuration 405 and / or beam configuration 410). Therefore, UE 115-f can send an indication 425 to UE 115-g (e.g., a beam switching indication can be signaled) for a corresponding beam switching (e.g., beam switching at UE 115-g). For example, UE 115-g can use a receive beam "M" quasi-co-located with beam configuration 410 (e.g., beam 4 of UE 115-f) and can use a transmit beam "N" quasi-co-located with beam configuration 405 (e.g., beam 5 of UE 115-f). Therefore, beams “M” and “N” at UE 115-g can be paired for full-duplex operation. After receiving an emergency data message from UE 115-g, UE 115-f can adjust beam configuration 405 (e.g., from narrow beam to wide beam) to monitor control waveforms (e.g., for other control indications 420).

[0140] Additionally or alternatively, UE 115-f may reduce the transmit power parameter associated with beam configuration 410. For example, UE 115-f may reduce the transmit power parameter by “X” dB to support self-interference mitigation. In some examples, “X” may depend on the level of self-interference (e.g., according to a rule, which could be an industry-standard rule). Additionally or alternatively, UE 115-f may send an indication 425 signal to UE 115-g to increase (e.g., boost) the transmit power by “Y” dB to improve data reception reliability associated with simultaneous data transmission and reception and to support improved self-interference mitigation.

[0141] In some examples, the control indication 420 can be cell-specific or UE-specific (e.g., as described herein, including references). Figure 2 For example, if network entity 105 (e.g., gNB) assigns UE-specific control signals to each UE 115, then UE 115-f can identify (e.g., determine, identify, detect) UE 115 (e.g., UE 115's device identifier) ​​and can pair with the corresponding full-duplex beam for full-duplex operation with UE 115 (e.g., UE 115-g). Furthermore, UE 115-f can stop (e.g., of message 415) transmission and switch to half-duplex operation based on receiving control indication 420 (e.g., to increase the likelihood of successfully receiving an emergency message from UE 115-g). Additionally or alternatively, UE 115-g can switch beam configurations 405 and 410, decrease the transmit power parameter in one or more parameters 430 associated with beam configuration 410, send an indication 425 notifying UE 115-g to increase the transmit power parameter, or any combination thereof, based on receiving control indication 420 (e.g., device-specific control indication).

[0142] Figure 5 An example of a process flow 500 supporting full-duplex collision handling and beam pairing according to one or more aspects of this disclosure is shown. In some examples, process flow 500 may implement aspects of wireless communication system 100, wireless communication system 300, wireless communication system 300, and wireless communication system 400. For example, process flow 500 may support signaling between UE 115-h, UE 115-i, UE 115-j, and UE 115-k. UE 115 of process flow 500 may be any of the following (including references): Figures 1 to 4 Examples of corresponding devices are provided. In the following description of process flow 500, operations between UE 115 may be performed in a different order than those shown, or other operations may be added to or removed from process flow 500. For example, some operations may be omitted from process flow 500, or may be performed in a different order or at different times. Furthermore, although some operations or signaling are shown to occur at different times for discussion purposes, these operations may occur simultaneously. Although UE 115 (e.g., a V2X device, a sidelink device) is shown performing operations of process flow 500, one or more aspects of process flow 500 may be additionally or alternatively performed by one or more other wireless or network devices (e.g., network entity 105).

[0143] At 505, UE 115-g can be configured for full-duplex communication (e.g., SFFD, SBFD can support full-duplex radio 305), and UE 115-h can send messages to UE 115-k (e.g., best-effort data service, data service 315). UE 115-k can also simultaneously monitor one or more control indications from other UE 115 (e.g., using full-duplex radio 305).

[0144] At 510, UE 115-h can receive (e.g., when sending a message at 505) a first control indication (e.g., control indication 320, emergency data transmission request) from UE 115-i. The first control indication may be associated with a first set of control indication parameters specific to UE 115-i. The first control indication may include a first request to send a message (e.g., emergency message, URLLC data) from UE 115-i to UE 115-h. In some examples, the first set of control indication parameters may include one or more first signal types, one or more first sequence parameters, one or more first reference signal parameters, one or more first waveform parameters, one or more first frequency resources, or any combination thereof.

[0145] At 515, UE 115-h can receive a second control instruction (e.g., control instruction 320) from UE 115-j (e.g., at the same time as receiving the first control instruction at 510 and sending a message at 505). The second control instruction may be associated with a second set of control instruction parameters specific to UE 115-j (e.g., different from the first set of control instruction parameters). The second control instruction may include a second request from UE 115-j to send a message (e.g., an emergency message, URLLC data) to UE 115-h. In some examples, the second set of control instruction parameters may include one or more second signal types, one or more second sequence parameters, one or more second reference signal parameters, one or more second waveform parameters, one or more second frequency resources, or any combination thereof. In some examples, UE 115-h may receive a first priority instruction (e.g., a priority index) associated with UE 115-i via the first control instruction and may receive a second priority instruction associated with UE 115-j via the second control instruction.

[0146] In some examples, the first control indication and the second control indication may at least partially overlap in the time domain, or they may not overlap in the time domain. The first control indication may be orthogonal to the second control indication in the frequency domain based on a first set of control indication parameters and a second set of control indication parameters. The UE 115-h may receive the first and second control indications via a sidelink channel.

[0147] At 520, UE 115-h can distinguish between a first control indication and a second control indication (e.g., or with multiple other control indications) (e.g., determine the differences between them, differentiate them). For example, UE 115 can distinguish a control indication based on a difference in at least one parameter between a first set of control indication parameters and a second set of control indication parameters (e.g., based on the fact that one or more of the corresponding control indication parameters are device-specific or unique to UE 115).

[0148] At point 525, UE 115-h may send a feedback message (e.g., feedback message 325) to UE 115-i, UE 115-j, or both. UE 115-h may send the feedback message via a sidelink channel. Sending the feedback message may be based on a first control indication and a second control indication (e.g., based on a distinguishing control indication, based on a determination associated with the corresponding control indication parameters). The feedback message may indicate whether UE 115-i, UE 115-j, or both wish to send a message to UE 115-h. The feedback message may be based on a corresponding priority indication of multiple received control indications. In some examples, UE 115-h may send a feedback message indicating that UE 115-i will send a first message based on determining that a first request (e.g., a first control indication) includes an indication for an emergency message request (e.g., a URLLC message).

[0149] UE 115-h can send a feedback message indicating that UE 115-i will send a first message based on a first priority indication (e.g., of UE 115-i) that is associated with a higher priority than a second priority indication (e.g., of UE 115-j). In some examples, sending the feedback message may include sending an ACK message to UE 115-i indicating that UE 115-i will send a first message based on the first priority associated with UE 115-i being higher than the second priority associated with UE 115-j. UE 115-h can also send a NACK message to UE 115-j indicating that UE 115-j will not send a second message.

[0150] In some examples, UE 115-h may send a first indication to UE 115-i (e.g., via a first feedback message) of a first time resource in which UE 115-i is permitted to send a first message. UE 115-h may also send a second indication to UE 115-j (e.g., via a second feedback message) of a second time resource in which UE 115-j will send a second message. For example, based on the fact that a first priority associated with UE 115-i is higher than a second priority associated with UE 115-j, the first time resource may precede the second time resource in the time domain. Additionally or alternatively, UE 115-h may send an indication of a time offset via a feedback message after which UE 115 (UE 115-j) receiving the feedback message will send a message to UE 115-h.

[0151] At 530, UE 115-h may have already scheduled the transmission of a message from UE 115-k to UE 115-h (e.g., before receiving control indications at 510 and 515). UE 115-h can determine whether UE 115-k should continue or cancel its transmission based on the appropriate priority associated with UE 115. For example, UE 115-h can send a first feedback message to UE 115-i indicating that UE 115-i will not transmit the first message, based on the fact that the priority associated with UE 115-k is higher than the priority associated with UE 115-i. UE 115-h can also send a second feedback message to UE 115-j indicating that UE 115-j will not transmit the second message, based on the fact that the first priority associated with UE 115-k is higher than the third priority associated with UE 115-j. Alternatively, UE 115-h may send a cancellation message (e.g., a feedback message including NACK, bit value or other cancellation indication) to UE 115-k based on a first priority associated with UE 115-k being lower than a second priority associated with UE 115-i or a third priority associated with UE 115-j.

[0152] Figure 6 An example of a process flow 600 supporting full-duplex collision handling and beam pairing according to one or more aspects of this disclosure is shown. In some examples, process flow 600 may implement aspects of wireless communication system 100, wireless communication system 300, wireless communication system 400, and process flow 500. For example, process flow 600 may support signaling between UE 115-m and UE 115-n. UE 115-m and UE 115-n of process flow 600 may be those described herein (including references). Figures 1 to 5Examples of corresponding devices are provided. In the following description of process flow 600, operations between UE 115-m and UE 115-n may be performed in a different order than shown, or other operations may be added to or removed from process flow 600. For example, some operations may also be omitted from process flow 600, or may be performed in a different order or at different times. Furthermore, although some operations or signaling are shown to occur at different times for discussion purposes, these operations may actually occur simultaneously. Although UE 115 (e.g., a V2X device, a sidelink device) is shown as performing operations of process flow 600, one or more aspects of process flow 600 may additionally or alternatively be performed by one or more other wireless or network devices (e.g., network entity 105).

[0153] At 605, UE 115-m can concurrently send a first message (e.g., message 415) to UE 115-n using a first beam configuration (e.g., beam configuration 410) and a second beam configuration (e.g., beam configuration 405) to monitor control indications from UE 115-n (e.g., control indication 420, which can monitor one or more sidelink channels). The control indications may include a request to send a second message from UE 115-n to UE 115-m. UE 115-m and UE 115-n can be configured for full-duplex communication.

[0154] At 610, UE 115-m can receive control instructions from UE 115-n based on monitoring. For example, UE 115-n may have an emergency message to transmit to UE 115-m and can send control instructions to UE 115-m (e.g., via a sidelink channel).

[0155] At 615, UE 115-m may adjust the first beam parameter (e.g., based on received control indication) among one or more parameters associated with the first beam configuration. For example, UE 115-m may adjust the first beam parameter such that the beamwidth associated with the first beam configuration is reduced (e.g., from a wide beam to a narrow beam). Additionally or alternatively, UE 115-m may reduce the transmit power parameter among one or more parameters associated with the first beam configuration. In some examples, the value of the transmit power parameter (e.g., or the value by which the transmit power is to be reduced) may be based on a self-interference metric associated with the first beam configuration and the second beam configuration.

[0156] At 620, UE 115-m may send an indication to UE 115-n of adjusted beam parameters (e.g., based on adjusting the first beam parameter). In some examples, communication with UE 115-n may be based on sending this indication. Additionally or alternatively, UE 115-m may send an indication (e.g., a command, a request) to UE 115-n to increase the transmit power parameter in one or more parameters associated with the second beam configuration. In some examples, the value of the transmit power parameter (e.g., or a value to reduce the transmit power) may be based on a self-interference metric associated with the first and second beam configurations.

[0157] At 625, UE 115-m can receive a second message from UE 115-n based on a transmission instruction. The second message can be associated with an emergency message (e.g., URLLC data).

For example, data, instructions, commands, information, signals, bits, symbols, and chips mentioned throughout the description can be represented by voltage, current, electromagnetic waves, magnetic fields or magnetic particles, light fields or optical particles, or any combination thereof.

[0304] The various exemplary blocks and components described herein can be implemented or performed using a general-purpose processor, DSP, ASIC, CPU, graphics processing unit (GPU), neural processing unit (NPU), FPGA or other programmable logic device, discrete gate or transistor logic unit, discrete hardware component, or any combination thereof designed to perform the functions described herein. A general-purpose processor may be a microprocessor, but in alternative embodiments, a processor may be any processor, controller, microcontroller, or state machine. A processor may also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors combined with a DSP core, or any other such configuration). Any function or operation described herein that can be performed by a processor may be performed by multiple processors capable of performing the described function or operation individually or jointly.

[0305] The functions described herein can be implemented using hardware, software executed by a processor, firmware, or any combination thereof. When implemented using software executed by a processor, the functions can be stored as one or more instructions or code on a computer-readable medium or transmitted using one or more instructions or code on a computer-readable medium. Other examples and specific implementations are within the scope of this disclosure and the appended claims. For example, due to the nature of software, the functions described herein can be implemented using software executed by a processor, hardware, firmware, hardwiring, or any combination of these. Features implementing the functions can also be physically located in various locations, including various portions distributed such that the functions are implemented in different physical locations.

[0306] Computer-readable media includes both non-transitory computer storage media and communication media, encompassing any medium that facilitates the transfer of a computer program from one location to another. Non-transitory storage media can be any available medium accessible by a general-purpose or special-purpose computer. By way of example, and not limitation, non-transitory computer-readable media may include RAM, ROM, electrically erasable programmable ROM (EEPROM), flash memory, compressed optical disc (CD) ROM or other optical disc storage devices, magnetic disk storage devices or other magnetic storage devices, or any other non-transitory medium that can be used to carry or store desired program code components in the form of instructions or data structures, and accessible by a general-purpose or special-purpose computer or a general-purpose or special-purpose processor. Furthermore, any connection is appropriately referred to as computer-readable media. For example, if software is transmitted from a website, server, or other remote source using coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies such as infrared, radio, and microwave, then coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included within the definition of computer-readable media. As used herein, disks and optical discs include CDs, laser discs, optical discs, digital multifunction discs (DVDs), floppy disks, and Blu-ray discs. Disks can magnetically reproduce data, and optical discs can optically reproduce data using lasers. Combinations of the above are also included within the scope of computer-readable media. Any function or operation described herein that can be performed by memory can be performed by multiple memories capable of performing the described function or operation individually or jointly.

[0307] As used herein, the word "or" in a list of items (e.g., a list of items accompanied by phrases such as "at least one of" or "one or more of") in the claims indicates an inclusive list, such that a list of at least one of, for example, A, B, or C means A or B or C or AB or AC or BC or ABC (i.e., A and B and C). Furthermore, as used herein, the phrase "based on" should not be construed as a reference to a closed set of conditions. For example, an example step described as "based on condition A" could be based on both condition A and condition B without departing from the scope of this disclosure. In other words, as used herein, the phrase "based on" should be interpreted in the same manner as the phrase "at least partially based on".

[0308] As used herein, including in claims, the article “a” preceding a noun is open-ended and is understood to refer to “at least one” or “one or more” of those nouns. Therefore, the terms “a,” “at least one,” “one or more,” and “at least one of one or more” are interchangeable. For example, where a claim enumerates “components” performing one or more functions, each of the individual functions may be performed by a single component or by any combination of multiple components. Thus, the term “component” having a characteristic or performing a function may refer to “at least one of one or more components” having a particular characteristic or performing a particular function. Subsequent references to a component introduced with the article “a” using the terms “the” or “the” can refer to any or all of the one or more components. For example, a component introduced with the article “a” can be understood to mean “one or more components,” and subsequent reference to “the component” in a claim can be understood as equivalent to referring to “at least one of the one or more components.” Similarly, subsequent references to a component introduced with the terms “the” or “the” as “one or more components” can refer to any or all of the one or more components. For example, reference to "the one or more components" in the subsequent claims can be understood as equivalent to reference to "at least one of the one or more components".

[0309] The term "determine" encompasses a wide range of actions, and therefore, "determine" can include calculation, computation, processing, derivation, investigation, lookup (such as by searching in a table, database, or other data structure), identification, and similar actions. Furthermore, "determine" can include receiving (e.g., receiving information), accessing (e.g., accessing data stored in memory), and so on. Moreover, "determine" can include parsing, obtaining, selecting, choosing, creating, and other similar actions.

[0310] In the accompanying drawings, similar components or features may have the same reference numerals. Furthermore, various components of the same type can be distinguished by adding a dash after the reference numeral and a second numeral for differentiation between similar components. If only the first reference numeral is used in the specification, the description applies to any of the similar components having the same first reference numeral, regardless of the second or other subsequent reference numerals.

[0311] The description herein, illustrated with reference to the accompanying drawings, describes an example configuration and does not represent all achievable examples or those within the scope of the claims. The term "example" as used herein means "serving as an example, instance, or illustration," not "preferred" or "advantageous over other examples." The detailed description includes specific details used to provide an understanding of the described techniques. However, these techniques can be practiced without these specific details. In some of the drawings, known structures and devices are shown in block diagram form to avoid obscuring the concept of the described examples.

[0312] The description herein is provided to enable those skilled in the art to implement or use this disclosure. Various modifications to this disclosure will be apparent to those skilled in the art, and the general principles defined herein may be applied to other variations without departing from the scope of this disclosure. Therefore, this disclosure is not limited to the examples and designs described herein, but should be granted the widest scope consistent with the principles and novel features disclosed herein.
