Frequency adjustment for sub-band full duplex conflict handling

Abstract

Methods, systems, and devices for wireless communication are described. In general, a user equipment (UE) may perform an adjustment procedure for one or more frequency resources of an uplink message or a downlink message to avoid collisions within a sub-band full duplex (SBFD) slot. In some cases, the UE may identify that a resource allocation for a downlink message extends over at least a portion of a resource allocation for an uplink message (or a guard band for the uplink message), and may perform an adjustment procedure for the uplink resource allocation. The adjustment process may include using only resources of the uplink resource allocation that do not overlap with resources of the downlink resource allocation, offsetting the uplink resource allocation within the uplink subband, or both. Additionally or alternatively, such techniques may be extended to adjust downlink resource allocation, for example, based on the type of downlink message.

Technical Field

[0002] This patent application claims the benefit of U.S. Patent Application No. 18 / 446,846, filed August 9, 2023, entitled “FREQUENCYADJUSTMENT FOR SUB-BAND FULL DUPLEX CONFLICT HANDLING”, which has been assigned to the assignee of this application and is expressly incorporated herein by reference. Technical Field

[0003] The following content relates to wireless communications, including frequency adjustment for subband full-duplex (SBFD) collision handling. Background Technology

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, message sending and receiving, broadcasting, and so on. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth-generation (4G) systems (such as Long Term Evolution (LTE) systems, LTE-A Advanced (LTE-A) systems, or LTE-A Pro systems) and fifth-generation (5G) systems (which may be referred to as New Radio (NR) systems). These systems 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 of communication devices, which may be referred to as User Equipment (UE). Summary of the Invention

[0005] The described techniques relate to improved methods, systems, devices, and apparatuses for frequency adjustment to support subband full-duplex (SBFD) collision handling. For example, the described techniques enable user equipment (UE) to perform adjustment procedures for one or more frequency resources for uplink or downlink messages to avoid collisions within SBFD time slots (e.g., time slots, micro-time slots, symbols, or other time periods that include uplink and downlink subbands or frequency resource allocations for multiple communication directions). In some cases, the UE may identify that a resource allocation for a downlink message extends over at least a portion of a resource allocation for an uplink message (or a guard band for an uplink message) and may perform adjustment procedures for the uplink resource allocation. The adjustment procedures may include using only resources of the uplink resource allocation that do not overlap with the resources of the downlink resource allocation, offsetting the uplink resource allocation within the uplink subband, or both. Such techniques can be extended to adjust downlink resource allocations, for example, based on the type of downlink message (e.g., whether the downlink message is a synchronization signal block (SSB)).

[0058] In some wireless communication systems, certain time slots (e.g., time-domain resource elements) can be configured to support sub-band full-duplex (SBFD) communication. For example, the bandwidth associated with an SBFD time slot can support multiple sub-bands in different communication directions, such as one or more downlink sub-bands and one or more uplink sub-bands (e.g., enabling devices to communicate simultaneously in two communication directions within an SBFD time slot). SBFD time slots can support enhancements in latency, coverage, system capacity, spectral efficiency, and system flexibility, among other advantages.

[0059] In some cases, a User Equipment (UE) can be an example of an SBFD-aware UE, indicating that the UE is still able to communicate during SBFD slots despite its capacity to limit (e.g., if the UE is configured for half-duplex communication). For example, uplink messages may be scheduled for transmission by the UE via the uplink subband of the SBFD slot at the same symbol as downlink messages transmitted via the downlink subband of the SBFD slot. However, some of these downlink messages may overlap at least partially with resources (e.g., resource blocks (RBs)) allocated to the uplink subband (or the guard band used for the uplink subband), which could interfere with the transmission of uplink messages by the UE, other UEs receiving downlink messages, or both.

[0060] To reduce or otherwise mitigate interference caused by resource conflicts at the same symbol within the SBFD time slot, the UE may perform an adjustment procedure to modify the resource allocation for uplink or downlink messages. In some cases, when a downlink resource allocation (e.g., for a periodic synchronization signal block (SSB)) overlaps with an uplink resource allocation at the same symbol in the SBFD, the UE may adjust the uplink resource allocation (e.g., for dynamically scheduled or semi-persistent uplink messages). For example, if a downlink resource allocation extends over a portion of an uplink resource allocation, the UE may adjust the uplink resource allocation to instead use the remainder of the original uplink allocation (e.g., using resources that do not overlap with the downlink resource allocation) to transmit uplink messages. Additionally or alternatively, the UE may offset the uplink resource allocation within an uplink subband (e.g., if sufficient resources are available within the uplink subband) to avoid conflicts with downlink resources. Similarly, the UE may perform such resource adjustments for downlink resource allocations (e.g., adjusting resources for monitoring downlink messages) to avoid conflicts with uplink messages. Such technologies can mitigate or reduce interference when UEs use SBFD time slots for communication, thereby improving network efficiency and SBFD communication.

In some examples, network entity 105 and UE 115 may wirelessly communicate via one or more communication links 125 (e.g., radio frequency (RF) access links). 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 one or more communication links 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).

For example, a node may be UE 115. Alternatively, a node may be network entity 105. Furthermore, a first node may be configured to communicate with a second or 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.

[0066] 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 one or more backhaul communication links 120 (e.g., according to S1, N2, N3, or other interface protocols). In some examples, network entities 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 links 120 (e.g., according to X2, Xn, or other interface protocols). In some examples, network entities 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. Backhaul communication link 120, midhaul communication link 162, or fronthaul communication link 168 may be or include one or more wired links (e.g., electrical links, fiber optic links), one or more wireless links (e.g., radio links, wireless optical links), etc., or various combinations thereof. UE 115 can communicate with core network 130 via communication link 155.

[0067] One or more network entities 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 105 (e.g., a single RAN node, such as base station 140).

[0068] 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 two or more network entities 105, such as an integrated access 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 central unit (CU) 160, a distributed unit (DU) 165, a radio unit (RU) 170, a RAN intelligent controller (RIC) 175 (e.g., a near real-time RIC, a non-real-time RIC), a service management and orchestration (SMO) 180 system, or any combination thereof. 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 105 in a decomposed RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0069] 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, and 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 higher protocol layer (e.g., Layer 3 (L3), Layer 2 (L2)) functionalities and signaling (e.g., Radio Resource Control (RRC), Serving Data Adaptation Protocol (SDAP), Packet Data Convergence Protocol (PDCP)). CU 160 can connect to one or more DU 165 or RU 170, and one or more DU 165 or RU 170 can 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 each can be at least partially controlled by CU 160. Additionally or alternatively, a protocol stack functional split can be employed between DU 165 and RU 170, such that DU 165 can support one or more layers of the protocol stack, and RU 170 can support one or more different layers of the protocol stack. DU 165 can support one or more different cells (e.g., via one or more RU 170). 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 different of CU 160, DU 165, or RU 170). CU 160 can be further functionally decomposed into CU control plane (CU-CP) and CU user plane (CU-UP) functions. CU 160 can be connected to one or more DU 165 via midhaul communication link 162 (e.g., F1, F1-c, F1-u), and DU 165 can be connected to one or more 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 the corresponding network entities 105 communicating via such communication links.

[0070] In some wireless communication systems (e.g., wireless communication system 100), the infrastructure and spectrum resources for radio access may 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 105 (e.g., IAB node 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as donor entities or IAB donors. One or more DU 165s or one or more RU 170s may be partially controlled by one or more CU 160s associated with donor network entity 105 (e.g., donor base station 140). One or more donor network entities 105 (e.g., IAB donors) may communicate with one or more additional network entities 105 (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 a DU 165 of a coupled IAB donor. The IAB-MT may include a separate set of antennas for relaying communication with UE 115, or may share the same antennas (e.g., those of RU 170) for access to IAB node 104 via DU 165 of IAB node 104. (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some examples, IAB node 104 may include a DU 165 that supports 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., one or more IAB nodes 104 or components of IAB node 104) may be configured to operate according to the techniques described herein.

[0071] In the context of applying the techniques described herein to a decomposed RAN architecture, one or more components of the decomposed RAN architecture may be configured to support frequency adjustments as described herein for SBFD conflict handling. 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., IAB node 104, DU 165, CU 160, RU 170, RIC 175, SMO 180).

[0072] 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 or vehicles, meters, etc.

[0073] The UE 115 described herein can communicate with various types of devices, such as other UEs 115 that sometimes act as relays, network entities 105, and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc. Figure 1 As shown.

[0074] UE 115 and network entity 105 can wirelessly communicate with each other via one or more communication links 125 (e.g., access links) using resources associated with one or more carriers. The term "carrier" can refer to a set of RF spectrum resources having a physical layer structure defined 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 physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating carrier operation, user data, or other signaling. Wireless communication system 100 may support communication with UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may 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, CU160, DU 165, RU 170) communicating with another device (e.g., directly or via one or more other network entities 105).

[0075] The communication link 125 shown in 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. A 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).

[0076] 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 bandwidth in a set of bandwidths for a particular radio access technology (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 carrier bandwidth in 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.

[0077] 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, in which case 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.

[0078] It can support one or more sets of parameters for a carrier, and the set of parameters 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, UE 115 can be configured with multiple BWPs. In some examples, a single BWP of a carrier can be active at a given time, and the communication of UE 115 can be constrained to one or more active BWPs.

[0079] 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, of which It can represent the supported subcarrier spacing, and This can represent the supported Discrete Fourier Transform (DFT) size. The time interval of the communication resources can be organized according to radio frames, each with a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0080] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may (e.g., in the time domain) be divided into subframes, and each subframe may be further divided into 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 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.

[0081] 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)).

[0082] 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 of the physical control channel (e.g., a control resource set (CORESET)) 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 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 multiple UEs 115, and a UE-specific search space set used to transmit control information to a specific UE 115.

[0083] 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 to communicate with network entity 105 (e.g., using a carrier) and may be associated with an identifier used to distinguish adjacent cells (e.g., Physical Cell Identifier (PCID), Virtual Cell Identifier (VCID), or other cell identifier). 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 range from smaller areas (e.g., structures, subsets of structures) to larger areas. For example, a cell may be or may include buildings, subsets of buildings, or external space between or overlapping coverage areas 110, etc.

[0084] Macro cells typically cover a relatively large geographical 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, small cells can be associated with a lower-power network entity 105 (e.g., a lower-power base station 140) and can operate using the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells can 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 can support one or more cells and can also use one or more component carriers to support communication via one or more cells.

[0085] 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 110. In some examples, different coverage areas 110 associated with different technologies may overlap, but the different coverage areas 110 may be supported by the same network entity 105. In some other examples, overlapping coverage areas 110 associated with different technologies may be supported by different network entities 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 radio access technologies to provide coverage for various coverage areas 110.

[0086] The wireless communication system 100 can support synchronous or asynchronous operation. For synchronous operation, network entities 105 (e.g., base station 140) can have similar frame timings, and transmissions from different network entities 105 can be approximately time-aligned. For asynchronous operation, network entities 105 can have different frame timings, and in some examples, transmissions from different network entities 105 may not be time-aligned. The techniques described herein can be used for both synchronous and asynchronous operation.

[0087] Some UE 115 devices (such as MTC or IoT devices) can be low-cost or low-complexity devices and can provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC can refer to data communication technologies that allow devices to communicate with each other or with 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 meters 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 geographic event monitoring, queue management and tracking, remote security sensing, physical access control, and transaction-based commercial charging.

[0088] Some UE 115s can be configured to operate in reduced-power modes, such as half-duplex communication (e.g., a mode that supports unidirectional communication via transmission or reception but does not involve concurrent transmission and reception). In some examples, half-duplex communication can be performed at reduced peak rates. 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., subcarriers or RB sets) within the carrier, within the carrier's guard band, or outside the carrier.

[0089] 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 or 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 prioritization of 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.

[0090] In some examples, UE 115 may be configured to support direct communication with other UE 115s via device-to-device (D2D) communication link 135 (e.g., according to peer-to-peer (P2P), D2D, or sidelink protocols). In some examples, one or more UE 115s performing D2D communication in a group 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 UE 115s 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, the group of UE 115s communicating via D2D communication may support a one-to-many (1:M) system, where each UE 115 transmits to each of the other UE 115s in the group. In some examples, network entity 105 may facilitate the scheduling of resources used for D2D communication. In other examples, D2D communication may be performed between UEs 115 without involving network entity 105.

[0091] In some systems, the D2D communication link 135 may be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, vehicles may communicate using vehicle-to-vehicle (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these. 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.

[0092] Core network 130 provides user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), and 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.

[0093] Wireless communication system 100 can operate using one or more frequency bands in the range of 300 MHz to 300 GHz. Generally, the region from 300 MHz to 3 GHz is referred to as the Ultra High Frequency (UHF) region 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 waves 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 100 km).

[0094] Wireless communication system 100 may utilize licensed and unlicensed RF spectrum bands. For example, wireless communication system 100 may use unlicensed frequency bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band) to employ licensed assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology. When operating with unlicensed RF spectrum bands, 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 combined with component carriers operating with licensed frequency bands based on carrier aggregation configurations (e.g., LAA). Operation using unlicensed spectrum may include downlink transmission, uplink transmission, P2P transmission, or D2D transmission, etc.

[0095] 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.

[0096] 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).

[0097] 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.

[0098] In some examples of the wireless communication system 100, UE 115 may communicate during an SBFD time slot, which can refer to any time duration (e.g., a time slot, micro-slot, symbol, etc., with uplink and downlink subbands or uplink and downlink resource allocations). For example, UE 115 may be an SBFD-aware UE, indicating that UE 115 is still capable of communicating during an SBFD time slot despite its capacity limitations (e.g., if UE 115 is a half-duplex UE). In some cases, to avoid conflicts between uplink and downlink messages within an SBFD time slot, UE 115 may perform an adjustment procedure for one or more frequency resources for either the uplink or downlink message. For example, UE 115 may identify that the resource allocation for the downlink message extends over at least a portion of the resource allocation for the uplink message (or the guard band for the uplink message) and may perform an adjustment procedure for the uplink resource allocation. This adjustment process may include using only uplink resource allocations that do not overlap with downlink resource allocations, offsetting uplink resource allocations within uplink subbands, or both. Such techniques can be extended to adjust downlink resource allocations, for example, based on the type of downlink message (e.g., whether the downlink message is an SSB). By performing this adjustment process, communication during SBFD slots can be improved.

[0099] Figure 2 An example of a wireless communication system 200 supporting frequency adjustment for SBFD collision handling according to one or more aspects of this disclosure is shown. The wireless communication system 200 may implement, or be implemented by, one or more aspects of the wireless communication system 100. For example, the wireless communication system 200 may include network entities 105-a and UE 115-a, which may be references... Figure 1 Examples of corresponding devices described. In some cases, wireless communication system 200 may support UE 115-a and network entity 105-a to perform communication 205, which may include uplink communication (e.g., transmission by UE 115-a and reception by network entity 105-a) and downlink communication (e.g., transmission by network entity 105-a and reception by UE 115-a).

[0100] UE 115-a and network entity 105-a may perform communication 205 via a set of time-frequency resources. For example, UE 115-a and network entity 105-a may communicate in the time domain during a set of time slots 210, including time slots 210-a, 210-b, 210-c, and 210-b. In some examples, each time slot 210 may be associated with one or more communication directions between UE 115-a and network entity 105-a. For example, time slots 210-a and 210-d may be examples of downlink time slots (e.g., associated with downlink resource 215), time slot 210-c may be an example of an uplink time slot (e.g., associated with uplink resource 220), and time slot 210-b may be an example of an SBFD time slot (e.g., associated with both downlink resource 215 and uplink resource 220).

[0101] In some examples, UE 115-a may receive resource allocations for one or more uplink messages 235 from network entity 105-a. For example, network entity 105-a may schedule one or more uplink messages 235 for UE 115-a to transmit during the corresponding symbol period of time slot 210-b and within the uplink subband of time slot 210-b. Such messages may be dynamically scheduled, may be based on periodic configuration, or may be activated from a semi-persistent configuration. For example, uplink messages 235 may be scheduled for UE 115-a to transmit based on scheduling by network entity 105-a, configuration for uplink messages 235, measurements in response to UE 115-a, priority rules based on UE 115-a, or any combination thereof. In some examples, since time slot 210-b is configured for SBFD communication, UE 115-a can identify resource allocation for downlink message 230, which is scheduled for communication at the same symbol as uplink message 235. For example, UE 115-a can receive an indication of resource allocation for downlink message 230 from network entity 105-a.

[0102] In some examples, resource allocation for downlink message 230 may extend into the uplink subband (or guard band for the uplink subband) of time slot 210-b, which could result in an overlap 225 (e.g., conflict) between the frequency resources allocated to downlink message 230 and those allocated to uplink message 235. For example, if downlink message 230 is a periodic downlink signal (e.g., SSB), network entity 105-a may allocate resources for each transmission of downlink message 230 before scheduling uplink message 235. Therefore, frequency resource allocation for downlink message 230 may be within the downlink resources 215 of downlink time slots 210-a and 210-d, but may extend into the uplink resources 220 of SBFD time slot 210-d (e.g., without dynamic adjustments from network entity 105-a).

[0103] In some cases, UE 115-a may perform an adjustment procedure for the resource allocation of uplink message 235 that conflicts with downlink message 230 during SBFD time slots (e.g., time slot 210-b). As an example of the adjustment procedure, UE 115-a may select a new frequency resource allocation for uplink message 235 from the portion of the original frequency resource allocation for uplink message 235 that does not overlap with downlink message 230, as referenced below. Figure 3 As described. As another example of the adjustment process, UE 115-a may use the frequency resource allocation offset for uplink message 235 within the uplink subband of SBFD slot 210, as referenced below. Figure 4 As described.

[0104] Additionally or alternatively, UE 115-a may perform such adjustments for the resource allocation used for downlink message 230 (e.g., without changing the frequency allocation used for uplink message 235). For example, UE 115-a may determine to adjust the frequency allocation used for downlink message 230 based on the type of downlink message 230 (e.g., if downlink message 230 is not an SSB), the frequency allocation used for uplink message 235 in the downlink subband extending to SBFD slot 210-b, or both. In such an example, UE 115-a may perform the adjustment procedure for downlink message 230 as described below. Figure 5 and Figure 6 As described.

[0105] In some cases, UE 115-a can adjust frequency resources for various combinations of message types, such as dynamically scheduled uplink message 235 and periodic or semi-persistent downlink message 230, periodic or semi-persistent uplink message 235 and dynamically scheduled downlink message 230, or periodic or semi-persistent uplink message 235 and periodic or semi-persistent downlink message 230. If both downlink message 230 and uplink message 235 are dynamically scheduled by network entity 105-a, overlap 225 can be avoided by scheduling by network entity 105-a (e.g., by not selecting conflicting resources). In some examples, UE 115-a can adjust frequency resources based on which message (e.g., downlink message 230 or uplink message 235) extends beyond the associated subband, as referenced. Figure 7 As described.

[0106] In some cases, UE 115-a may determine the type of adjustment procedure to apply based on one or more rules (e.g., autonomously after identifying overlap 225). For example, UE 115-a may identify one or more pre-configured rules (e.g., rules predefined in the standard) for selecting an adjustment procedure from one or more candidate adjustment procedures. In some cases, one or more rules may indicate which adjustment procedure to use based on overlap 225 (e.g., the number of overlapping RBs), the configuration of SBFD slot 210-b (e.g., the number of RBs allocated to each subband), or both.

[0107] Additionally or alternatively, network entity 105-a may send a message to UE 115-a indicating the type of adjustment procedure to be applied (e.g., in the case of overlap 225). In some examples, network entity 105-a may send such information via RRC messages (e.g., for periodic code group timings that may overlap with SSB timings), Media Access Control Control Element (MAC-CE), or Downlink Control Information (DCI) messages. In some examples, network entity 105-a may send the message as a UE-specific message (e.g., specific to UE 115-a), a group-shared message (e.g., sent to a group of UEs 115 including UE 115-a), a broadcast message (e.g., sent to each UE 115 in the cell serving UE 115-a), or any combination thereof.

[0108] Figure 3An example of resource diagram 300 supporting frequency adjustment for SBFD collision handling according to one or more aspects of this disclosure is shown. Resource diagram 300 may implement, or be implemented by, one or more aspects of wireless communication systems 100 and 200. For example, resource diagram 300 may support communication between UE 115 and network entity 105 during time slot 305, the UE and the network entity being references. Figure 1 and Figure 2 Examples of the corresponding devices described. In some cases, time slot 305 can be an SBFD time slot (such as reference). Figure 2 The example described is time slot 210-b). For example, time slot 305 may include downlink subbands 310-a and 310-b for conveying downlink signaling, and uplink subband 315 for conveying uplink signaling. It should be noted that time slot 305 may support any configuration or ordering of subbands supported by SBFD, and is therefore not limited to... Figure 3 The example shown.

[0109] Resource diagram 300 illustrates adjustment procedure 320, which can be a first example of an adjustment procedure for handling resource conflicts in SBFD slots. Adjustment procedure 320 can be performed for uplink resource allocation 325 (e.g., for conveying uplink messages). In some cases, UE 115 can perform adjustment procedure 320 based on the overlap between uplink resource allocation 325 and downlink resource allocation 330 (e.g., for conveying downlink messages). For example, downlink resource allocation 330 can be configured for periodic SSB and can extend into uplink subband 315 (or guard band 340 between downlink subband 310-b and uplink subband 315) during SBFD slot 305. In such examples, downlink resource allocation 330 can overlap with uplink resource allocation 325 if uplink resource allocation 325 occupies the entire uplink subband 315.

[0110] To avoid interference caused by the overlap between downlink resource allocation 330 and uplink resource allocation 325, UE 115 may perform an adjustment procedure 320 for uplink resource allocation 325 to obtain an adjusted uplink resource allocation 335 (e.g., an adjustment of resources used for transmitting uplink messages). The adjustment procedure 320 may include selecting resources from the original uplink resource allocation 325 for the adjusted uplink resource allocation 335 such that the resource interval (e.g., in frequency) between the adjusted uplink resource allocation 335 and downlink resource allocation 330 satisfies the same number of RBs (e.g., a threshold number of N RBs) as the guard band 340. For example, as part of the adjustment procedure 320, UE 115 may select resources from the portion of uplink resource allocation 325 that does not overlap with downlink resource allocation 330 for the adjusted uplink resource allocation 335 (e.g., using N RBs of that portion as a guard band and using the remaining RBs of that portion for the adjusted uplink resource allocation 335).

[0111] In some cases, due to the execution of adjustment procedure 320, UE 115 may adjust the data rate of uplink messages. For example, the adjusted uplink resource allocation 335 may include fewer frequency resources (e.g., RBs) than uplink resource allocation 325, and UE 115 may reduce the data rate of uplink messages to support data transmission using the reduced number of frequency resources. Alternatively, UE 115 may apply uplink rate matching to the adjusted uplink resource allocation 335, which may allow UE 115 to maintain the same data rate used to transmit uplink messages (e.g., the same as the original data rate configured for uplink messages). For example, UE 115 may indicate to network entity 105 its ability to perform uplink rate matching and may transmit uplink messages via the adjusted uplink resource allocation 335 after applying uplink rate matching.

[0112] Figure 4 An example of a resource diagram 400 supporting frequency adjustment for SBFD collision handling according to one or more aspects of this disclosure is shown. Resource diagram 400 may implement, or be implemented by, one or more aspects of wireless communication systems 100 and 200. For example, resource diagram 400 may support communication between UE 115 and network entity 105 during time slot 405, the UE and the network entity being references. Figure 1 and Figure 2 Examples of the corresponding devices described. In some cases, time slot 405 can be an SBFD time slot (such as reference). Figure 2The example described is time slot 210-b). For example, time slot 405 may include downlink subbands 410-a and 410-b for conveying downlink signaling, and uplink subband 415 for conveying uplink signaling. It should be noted that time slot 405 may support any configuration or ordering of subbands supported by SBFD, and is therefore not limited to... Figure 4 The example shown.

[0113] Resource diagram 400 illustrates adjustment procedure 420, which can be a second example of an adjustment procedure for handling resource conflicts in SBFD slots. Adjustment procedure 420 can be performed for uplink resource allocation 425 (e.g., for conveying uplink messages). In some cases, UE 115 can perform adjustment procedure 420 based on the overlap between uplink resource allocation 425 and downlink resource allocation 430 (e.g., for conveying downlink messages). For example, downlink resource allocation 430 can be configured for periodic SSB and can extend into uplink subband 415 (or guard band 440 between downlink subband 410-b and uplink subband 415) during SBFD slot 405. In such examples, downlink resource allocation 430 can overlap with uplink resource allocation 425 within uplink subband 415.

[0114] To avoid interference caused by the overlap between downlink resource allocation 430 and uplink resource allocation 425, UE 115 may perform an adjustment procedure 420 for uplink resource allocation 425 to obtain an adjusted uplink resource allocation 435 (e.g., an adjustment of resources used for transmitting uplink messages). The adjustment procedure 420 may include UE 115 offsetting uplink resource allocation 425 within uplink subband 415 to obtain the adjusted uplink resource allocation 435. For example, UE 115 may identify the remaining number of RBs (e.g., available RBs) in uplink subband 415 that are not part of uplink resource allocation 425, and may offset uplink resource allocation 425 to occupy available RBs, such that the adjusted uplink resource allocation 435 and downlink resource allocation 430 do not overlap (e.g., offsetting uplink resource allocation 425 away from downlink resource allocation 430).

[0115] Additionally, UE 115 can offset uplink resource allocation 425 such that the resource interval between the adjusted uplink resource allocation 435 and downlink resource allocation 430 satisfies the same number of RBs as guard band 440 (e.g., a threshold number of N RBs). In such an example, since uplink resource allocation 425 and adjusted uplink resource allocation 435 include the same number of RBs, UE 115 can maintain the same data rate for uplink message transmission.

[0116] Figure 5 An example of a resource diagram 500 supporting frequency adjustment for SBFD collision handling according to one or more aspects of this disclosure is shown. Resource diagram 500 may implement, or be implemented by, one or more aspects of wireless communication systems 100 and 200. For example, resource diagram 500 may support communication between UE 115 and network entity 105 during time slot 505, the UE and the network entity being references. Figure 1 and Figure 2 Examples of the corresponding devices described. In some cases, time slot 505 can be an SBFD time slot (such as reference). Figure 2 The example described is time slot 210-b). For example, time slot 505 may include downlink subbands 510-a and 510-b for transmitting downlink signaling, and uplink subband 515 for transmitting uplink signaling. It should be noted that time slot 505 may support any configuration or ordering of subbands supported by SBFD, and is therefore not limited to... Figure 5 The example shown.

[0117] Resource diagram 500 illustrates adjustment procedure 520, which can be a third example of an adjustment procedure for handling resource conflicts in SBFD slots. Adjustment procedure 520 can be performed for downlink resource allocation 525 (e.g., for conveying downlink messages). In some cases, adjustment procedure 520 can be performed for downlink resource allocation 525 based on the type of downlink message associated with it (e.g., if the downlink message is not an SSB). In some cases, UE 115 can perform adjustment procedure 520 based on the overlap between downlink resource allocation 525 and uplink resource allocation 530 (e.g., for conveying uplink messages). For example, uplink resource allocation 530 can extend into downlink subband 510-b (or guard band 540 between downlink subband 510-b and uplink subband 515) during SBFD slot 505. In such examples, if downlink resource allocation 525 occupies the entire downlink subband 510-b, then uplink resource allocation 530 may overlap with downlink resource allocation 525.

[0118] To avoid interference caused by the overlap between downlink resource allocation 525 and uplink resource allocation 530, UE 115 may perform an adjustment procedure 520 for downlink resource allocation 525 to obtain an adjusted downlink resource allocation 535 (e.g., an adjustment of resources for monitoring the reception of downlink messages). The adjustment procedure 520 may include selecting resources from the original downlink resource allocation 525 for the adjusted downlink resource allocation 535 such that the resource interval (e.g., in frequency) between the adjusted downlink resource allocation 535 and the uplink resource allocation 530 satisfies the same number of RBs (e.g., a threshold number of N RBs) as the guard band 540. For example, as part of the adjustment procedure 520, UE 115 may select resources from the portion of downlink resource allocation 525 that does not overlap with uplink resource allocation 530 for the adjusted downlink resource allocation 535 (e.g., using N RBs of that portion as a guard band and using the remaining RBs of that portion for downlink resource allocation 535).

[0119] In some cases, due to the execution of adjustment procedure 520, UE 115 may adjust the data rate of downlink messages. For example, the adjusted downlink resource allocation 535 may include fewer frequency resources (e.g., RBs) than downlink resource allocation 525, and UE 115 may reduce the data rate while monitoring downlink messages to support receiving data using the reduced number of frequency resources. Alternatively, UE 115 may apply downlink rate matching to the adjusted downlink resource allocation 535, which allows UE 115 to maintain the same data rate used to receive downlink messages (e.g., the same as the original data rate configured for downlink messages).

[0120] Figure 6 An example of a resource diagram 600 supporting frequency adjustment for SBFD collision handling according to one or more aspects of this disclosure is shown. Resource diagram 600 may implement, or be implemented by, one or more aspects of wireless communication systems 100 and 200. For example, resource diagram 600 may support communication between UE 115 and network entity 105 during time slot 605, the UE and the network entity being references. Figure 1 and Figure 2 Examples of the corresponding devices described. In some cases, time slot 605 can be an SBFD time slot (such as reference). Figure 2 The example described is time slot 210-b). For example, time slot 605 may include downlink subbands 610-a and 610-b for conveying downlink signaling, and uplink subband 615 for conveying uplink signaling. It should be noted that time slot 605 may support any configuration or ordering of subbands supported by SBFD, and is therefore not limited to... Figure 6 The example shown.

[0121] Resource diagram 600 illustrates adjustment procedure 620, which can be a fourth example of an adjustment procedure for handling resource conflicts in SBFD slots. Adjustment procedure 620 can be performed for downlink resource allocation 625 (e.g., for conveying downlink messages). In some cases, adjustment procedure 620 can be performed for downlink resource allocation 625 based on the type of downlink message associated with it (e.g., if the downlink message is not an SSB). In some cases, UE 115 can perform adjustment procedure 620 based on the overlap between downlink resource allocation 625 and uplink resource allocation 630 (e.g., for conveying uplink messages). For example, uplink resource allocation 630 can extend into downlink subband 610-b (or guard band 640 between downlink subband 610-b and uplink subband 615) during SBFD slot 605. In such examples, downlink resource allocation 625 can overlap with uplink resource allocation 630 within downlink subband 610-b.

[0122] To avoid interference caused by the overlap between downlink resource allocation 625 and uplink resource allocation 630, UE 115 may perform an adjustment procedure 620 for downlink resource allocation 625 to obtain an adjusted downlink resource allocation 635 (e.g., an adjustment of resources for monitoring the reception of downlink messages). The adjustment procedure 620 may include UE 115 offsetting downlink resource allocation 625 within downlink subband 610-b to obtain the adjusted downlink resource allocation 635. For example, UE 115 may identify the remaining number of RBs (e.g., available RBs) in downlink subband 610-b that are not part of downlink resource allocation 625, and may offset downlink resource allocation 625 to occupy available RBs so that the adjusted downlink resource allocation 635 and uplink resource allocation 630 do not overlap (e.g., offsetting downlink resource allocation 625 to a different frequency resource than uplink resource allocation 630).

[0123] Additionally, UE 115 can offset downlink resource allocation 625 such that the resource interval between the adjusted downlink resource allocation 635 and uplink resource allocation 630 satisfies the same number of RBs as guard band 640 (e.g., a threshold number of N RBs). In such an example, since downlink resource allocation 625 and adjusted downlink resource allocation 635 include the same number of RBs, UE 115 can maintain the same data rate for receiving uplink messages.

[0124] Figure 7An example of a resource diagram 700 supporting frequency adjustment for SBFD collision handling according to one or more aspects of this disclosure is shown. Resource diagram 700 may implement, or be implemented by, one or more aspects of wireless communication systems 100 and 200. For example, resource diagram 700 may support communication between UE 115 and network entity 105 during time slot 705, the UE and the network entity being references. Figure 1 and Figure 2 Examples of the corresponding devices described. In some cases, time slot 705 can be an SBFD time slot (such as reference 705). Figure 2 The example described is time slot 210-b). For example, time slot 705 may include downlink subbands 710-a and 710-b for conveying downlink signaling, and uplink subband 715 for conveying uplink signaling. It should be noted that time slot 705 may support any configuration or ordering of subbands supported by SBFD, and is therefore not limited to... Figure 7 The example shown.

[0125] Resource diagram 700 illustrates adjustment procedure 720, which can be a fifth example of an adjustment procedure for handling resource conflicts in SBFD slots. Adjustment procedure 720 can be performed for uplink resource allocation 725 (e.g., for conveying uplink messages) or downlink resource allocation 730 (e.g., for conveying downlink messages) based on which resource allocation extends beyond the associated subband. For example, if uplink resource allocation 725 extends into downlink subband 710-b (or the guard band between uplink subband 715 and downlink subband 710-b) and overlaps with downlink resource allocation 730, then UE 115 can perform adjustment procedure 720-a for uplink resource allocation 725 to obtain adjusted uplink resource allocation 735. Alternatively, if downlink resource allocation 730 extends into uplink subband 715 (or the guard band between uplink subband 715 and downlink subband 710-b) and overlaps with uplink resource allocation 725, then UE 115 may perform adjustment procedure 720-b for downlink resource allocation 730 to obtain adjusted downlink resource allocation 740.

[0126] In some cases, adjustment process 720 can be used as a reference. Figure 3 – Figure 6 An example of the described adjustment process. For instance, adjustment process 720-a may include UE 115 selecting an adjusted uplink resource allocation 735 from uplink resource allocation 725 (e.g., in the case of applying or not applying rate matching), as referenced. Figure 3As described. Alternatively, the adjustment process 720-a may include UE 115 offsetting uplink resource allocation 725 away from downlink resource allocation 730 (e.g., offsetting to uplink subband 715) to obtain an adjusted uplink resource allocation 735, as referenced. Figure 4 As described. Similarly, the adjustment process 720-b may include UE 115 selecting an adjusted downlink resource allocation 740 from downlink resource allocation 730 (e.g., applying or not applying rate matching), as referenced. Figure 5 As described. Alternatively, the adjustment process 720-b may include UE115 offsetting downlink resource allocation 730 away from uplink resource allocation 725 (e.g., offsetting it to downlink subband 710-b) to obtain an adjusted downlink resource allocation 740, as described in reference. Figure 6 As described.

[0127] Figure 8 An example of a process flow 800 supporting frequency adjustment for SBFD collision handling according to one or more aspects of this disclosure is shown. Process flow 800 may implement or be implemented by one or more aspects of wireless communication systems 100 and 200 and resource diagrams 300, 400, 500, 600, and 700. For example, process flow 800 may be implemented using reference... Figures 1 to 7 The described technique is an example of signaling between UE 115-b and network entity 105-b to handle frequency resource conflicts during SBFD time slots. Alternative examples of the following may be implemented, some of which may be performed in a different order than described, or not at all. In some cases, the procedures may include additional features not mentioned below, or additional procedures may be added.

[0128] At 805, UE 115-b may send a capability report to network entity 105-b indicating one or more capabilities of UE 115-b. For example, the capability report may indicate UE 115-b's ability to apply rate matching (e.g., uplink rate matching or downlink rate matching).

[0129] At 810, network entity 105-b may send a control message (referred to herein as a third control message) to UE 115-b instructing on the configuration of an adjustment procedure. For example, network entity 105-b may configure UE 115-b with one or more types of adjustment procedures to be used in the event of a resource conflict. In some cases, this type may instruct UE 115-b to select a new resource allocation from the original resource allocation, offset the original resource allocation to obtain the new resource allocation, or both. In some cases, the control message may be specific to UE 115-b, associated with a group of UE 115s including UE 115-b, or broadcast to each UE 115 of the cell including UE 115-b.

[0130] At 815, network entity 105-b may send a first control message to UE 115-b, the first control message indicating one or more first frequency resources associated with a first signal having a first communication direction (e.g., uplink or downlink) between UE 115-b and network entity 105-b and allocated within the SBFD time slot. For example, the one or more first frequency resources may indicate an uplink resource allocation for UE 115-b to transmit uplink messages. Alternatively, the one or more first frequency resources may indicate a downlink resource allocation for UE 115-b to monitor downlink messages. In some cases, the first control message may dynamically schedule the first signal or may activate the first signal for semi-persistent scheduling.

[0131] At 820, network entity 105-b may send a second control message to UE 115-b, the second control message indicating one or more second frequency resources associated with a second signal having a second communication direction different from the first communication direction between UE 115-b and network entity 105-b. In some cases, the one or more second frequency resources may be allocated in SBFD time slots at the same symbol as the one or more first frequency resources (e.g., in the time domain) and may at least partially overlap with the one or more frequency resources in the frequency domain. In some cases, the first signal may be dynamically scheduled, and the second signal may be periodically scheduled or semi-persistently scheduled. Alternatively, the first signal may be periodically scheduled or semi-persistently scheduled, and the second signal may be dynamically scheduled. Alternatively, the first signal may be periodically scheduled or semi-persistently scheduled, and the second signal may be periodically scheduled or semi-persistently scheduled.

[0132] At 825, UE 115-b may perform an adjustment procedure for one or more first frequency resources to obtain one or more third frequency resources for the transmission of a first signal. In some cases, the performance of the adjustment procedure may be based on the fact that one or more second frequency resources at least partially overlap with one or more first frequency resources in the frequency domain. In some cases, UE 115-b may use an adjustment procedure indicated by network entity 105-b. Alternatively, UE 115-b may select the type of adjustment procedure from a set of multiple types of adjustment procedures (e.g., autonomously) based on one or more rules (e.g., predefined in the standard), which are based on the fact that one or more second frequency resources at least partially overlap with one or more first frequency resources in the frequency domain.

[0133] In some cases, one or more first frequency resources and one or more third frequency resources may be allocated within a first subband of the SBFD time slot configured for a first communication direction, and one or more second frequency resources may be allocated at least partially within the first subband or at least partially within a guard band between the first subband and a second subband of the SBFD time slot configured for a second communication direction (e.g., extending out of the associated subband). In such examples, UE 115-b may adjust one or more first frequency resources (e.g., to accommodate one or more second frequency resources extending into the first subband).

[0134] For example, UE 115-b can perform an adjustment process by selecting one or more third frequency resources from one or more first frequency resources (e.g., a subset of one or more first frequency resources), wherein the resource spacing between the one or more third frequency resources and one or more second frequency resources in the frequency domain satisfies a threshold number of RBs corresponding to the size of the guard band. Furthermore, UE 115-b can select one or more third frequency resources from portions of the one or more first frequency resources that do not overlap with the one or more second frequency resources. In some cases, UE 115-b can reduce the data rate of the first signal based on the fact that one or more third frequency resources include fewer RBs than one or more first frequency resources. Alternatively, UE 115-b can apply rate matching to one or more third frequency resources to maintain the same data rate configured for the first signal (e.g., based on an indication capability report).

[0135] For example, UE 115-b can perform an adjustment process by shifting one or more first frequency resources within a first subband to obtain one or more third frequency resources. In some cases, the one or more first frequency resources and the one or more third frequency resources may include the same number of RBs (e.g., maintaining the same data rate for the first signal). For example, UE 115-b can shift one or more first frequency resources away from one or more second frequency resources within a first subband such that the one or more third frequency resources and the one or more second frequency resources do not overlap.

[0136] For example, one or more second frequency resources may be allocated within a second subband of an SBFD time slot configured for a second communication direction, and one or more first frequency resources may be allocated at least partially within the second subband (e.g., extending into an associated subband). In such an example, UE 115-b may perform an adjustment procedure for one or more first frequency resources based on the fact that one or more first frequency resources are allocated at least partially within the second subband. In other words, UE 115-b may perform an adjustment procedure for resources extending into an incorrect subband (e.g., uplink resources in a downlink subband or downlink resources in an uplink subband).

[0137] At 830, UE 115-b and network entity 105-b may, according to the adjustment procedure, transmit a first signal via one or more third frequency resources, a second signal via one or more second frequency resources, or both during the SBFD time slot. In some cases, interference caused by overlap between one or more first frequency resources and one or more second frequency resources can be avoided by performing the adjustment procedure on one or more first frequency resources.

The communication manager 1620 is capable of, configured to, or able to operate to support components for performing the following operations: during the SBFD time slot, transmitting a first signal with the UE via one or more third frequency resources, transmitting a second signal via one or more second frequency resources, or both, wherein the one or more third frequency resources are based on an adjustment process for one or more first frequency resources, and wherein the adjustment process is based on the one or more second frequency resources at least partially overlapping with one or more first frequency resources in the frequency domain.

[0214] By including or configuring a communication manager 1620 according to an example as described herein, device 1605 can support techniques for improving SBFD communication, thereby improving system efficiency, capacity, and latency.

[0215] In some examples, the communication manager 1620 may be configured to use or otherwise coordinate with the transceiver 1610, one or more antennas 1615 (e.g., where applicable), or any combination thereof to perform various operations (e.g., receiving, acquiring, monitoring, outputting, transmitting).

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 working in conjunction 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 functions or operations individually or jointly.

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 portions distributed such that the functions are implemented in different physical locations.

[0273] 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.

[0274] 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".

[0275] 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".

[0276] The term "determine" encompasses a variety 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), etc. Moreover, "determine" can include parsing, acquiring, selecting, choosing, creating, and other similar actions.

[0277] 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 reference numeral to differentiate them. If only the first reference numeral is used in the description, the description can be applied to any of the similar components having the same first reference numeral, regardless of the second or other subsequent reference numerals.

[0278] 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 instances, known structures and devices are shown in block diagram form to avoid obscuring the concept of the described examples.

[0279] 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.
