The SBFD configuration may indicate a first set of resources for downlink communication and a second set of resources for uplink communication. The first set of resources and the second set of resources may include non-overlapping frequency resources in the same time interval. The UE may receive a control message indicating preemption of the first set of resources or cancellation of the second set of resources.

Technical Field

[0003] The following relates to wireless communications, including downlink preemption and uplink cancellation for full-duplex systems. Background Art

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasting, and the like. These systems may be able to support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth generation (4G) systems (such as long term evolution (LTE) systems, advanced LTE (LTE-A) systems, or LTE-A Pro systems) and fifth generation (5G) systems (which may be referred to as new radio (NR) systems). These systems may employ techniques such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations, each of which supports wireless communications for communication devices, which may be referred to as user equipment (UE).

[0044] Some communication devices, such as user equipment (UE) or network entities, may be capable of performing simultaneous transmission and reception according to a full-duplex communication scheme. For example, in a sub-band full-duplex (SBFD) communication scheme, a communication device may use different (non-overlapping) portions of a radio frequency (RF) spectrum band for uplink and downlink operations. In a single-frequency full-duplex (SFFD) communication scheme, a communication device may use code division multiplexing (CDM) or space division multiplexing (SDM) to perform concurrent uplink and downlink operations on resources that overlap in time and frequency. In other full-duplex communication schemes, a communication device may perform simultaneous uplink and downlink operations on resources that partially overlap in time or frequency.

[0045] In some cases, performing simultaneous transmission and reception at a communication device may result in self-interference at the communication device or cross-link interference (CLI) at other communication devices. For example, a downlink transmission from a first network entity may result in CLI at a second network entity that is receiving an uplink transmission from a UE. In order to cancel or silence a transmission that may potentially result in CLI, the network entity may send downlink control information (DCI) including one or more cancellation indications (for uplink communications) or preemption indications (for downlink communications). However, these indications may not be applicable to some channels and transmission types. Therefore, conventional mechanisms cannot mitigate CLI in full-duplex systems.

[0046] Various aspects of the present disclosure improve the flexibility of cancellation indications and preemption indications by configuring different silent modes for different communication schemes. For example, if SBFD communication is configured for the serving cell of the UE, the cancellation indication may apply to all uplink transmission types and channels. Otherwise, the cancellation indication may apply to a subset of uplink channels and transmission types. Similarly, if SBFD communication is enabled for the serving cell, the preemption indication may apply to all downlink transmission types and channels. If SBFD communication is disabled (or not configured), the preemption indication may apply to a subset of downlink channels and priority levels.

[0047] In some examples, the UE may determine, based on the SBFD configuration of the cell serving the UE (e.g., if SBFD communication is enabled for the cell), that the cancellation indication is applicable to a physical uplink control channel (PUCCH) transmission, a physical uplink shared channel (PUSCH) transmission, a physical random access channel (PRACH) transmission, a sounding reference signal (SRS) transmission, or a combination thereof. Similarly, the UE may determine, based on the SBFD configuration of the cell, that the preemption indication is applicable to a synchronization signal block (SSB) transmission and a physical broadcast channel (PBCH) transmission. In some examples, the network entity may indicate a silent mode via UE-specific signaling or group common signaling. The silent mode may indicate time and frequency resources in which uplink transmissions are canceled or downlink transmissions are not expected.

[0048] Various aspects of the present disclosure may be implemented to achieve one or more of the following advantages. The described techniques may reduce CLI caused by full-duplex communications at one or more network entities. For example, a first network entity with SBFD capability may use one or more preemption indications (signaled via DCI) or silent modes (indicated via UE-specific signaling or group-common signaling) to preempt one or more SSB or PBCH transmissions that overlap with uplink transmissions to a second network entity, thereby reducing the likelihood that SSB or PBCH transmissions (from the first network entity) will cause CLI at the second network entity.

[0049] Aspects of the present disclosure are first described in the context of wireless communication systems, resource diagrams, and process flows. Aspects of the present disclosure are further illustrated by apparatus diagrams, system diagrams, and flow diagrams involving downlink preemption and uplink cancellation for full-duplex systems, and are described with reference to these diagrams.

[0050] Figure 1 An example of a wireless communication system 100 that supports downlink preemption and uplink cancellation for a full-duplex system according to one or more aspects of the present disclosure is illustrated. The wireless communication system 100 may include one or more network entities 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an Advanced LTE (LTE-A) network, an LTE-A Pro network, a New Radio (NR) network, or a network operating according to other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.

[0051] The network entities 105 may be dispersed throughout a geographic area to form the wireless communication system 100, and may include devices in different forms or with different capabilities. In various examples, the network entities 105 may be referred to as network elements, mobility elements, radio access network (RAN) nodes, or network equipment, among other nomenclature. In some examples, the network entities 105 and the UE 115 may communicate wirelessly via one or more communication links 125 (e.g., radio frequency (RF) access links). For example, the network entity 105 may support a coverage area 110 (e.g., a geographic coverage area) within which the UE 115 and the network entity 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area within which the network entity 105 and the UE 115 may support signal communications according to one or more radio access technologies (RATs).

[0052] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary or mobile, or stationary and mobile at different times. The UEs 115 may be devices in different forms or with different capabilities. Figure 1 Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be capable of supporting communication with various types of devices such as Figure 1 Other UEs 115 or network entities 105 are shown communicating.

[0053] As described herein, a node of the wireless communication system 100 (which may be referred to as a network node or a 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, an apparatus, a device, a computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, the node may be a UE 115. As another example, the node may be a 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 a UE 115, the second node may be a network entity 105, and the third node may be a UE 115. In another aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a network entity 105. In other aspects of this example, the first node, the second node, and the third node may be different relative to these examples. Similarly, references to UE 115, network entity 105, apparatus, device, computing system, etc. may include disclosure of UE 115, network entity 105, apparatus, device, computing system, etc. as nodes. For example, a disclosure that UE 115 is configured to receive information from network entity 105 also discloses that the first node is configured to receive information from the second node.

[0054] In some examples, the network entities 105 may communicate with the core network 130, or with each other, or both. For example, the network entities 105 may communicate with the 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, the network entities 105 may communicate with each other via the backhaul communication links 120 (e.g., according to X2, Xn, or other interface protocols) directly (e.g., directly between the network entities 105) or indirectly (e.g., via the core network 130). In some examples, the network entities 105 may communicate with each other via the midhaul communication links 162 (e.g., according to the midhaul interface protocol) or the fronthaul communication links 168 (e.g., according to the fronthaul interface protocol) or any combination thereof. The backhaul communication links 120, the midhaul communication links 162, or the fronthaul communication links 168 may be or include one or more wired links (e.g., electrical links, optical fiber links), one or more wireless links (e.g., radio links, wireless optical links), etc. or various combinations thereof. UE 115 may communicate with core network 130 via communication link 155 .

[0055] One or more of the network entities 105 described herein may include or may be referred to as a base station 140 (e.g., a transceiver base station, a radio base station, an NR base station, an access point, a radio transceiver, a Node B, an evolved Node B (eNB), a next generation Node B, or a Gigabit Node B (any of which may be referred to as a gNB), a 5G NB, a next generation eNB (ng-eNB), a home Node B, a home evolved Node B, or other suitable terms). In some examples, the network entity 105 (e.g., a base station 140) may be implemented in an aggregated (e.g., monolithic, stand-alone) base station architecture, which may be configured to utilize a protocol stack physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as a base station 140).

[0056] In some examples, the network entity 105 may be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) that may be configured to utilize a protocol stack that is physically or logically distributed between 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, the 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 (near RT RIC), a non-real-time RIC (non-RT RIC)), a service management and orchestration (SMO) 180 system, or any combination thereof. The RU 170 may also be referred to as a radio head, a smart radio head, a remote radio head (RRH), a remote radio unit (RRU), or a transmit receive point (TRP). One or more components of the network entity 105 in the decomposed RAN architecture may be co-located, or one or more components of the network entity 105 may be located in distributed locations (e.g., separate physical locations). In some examples, one or more network entities 105 of the decomposed RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0057] The functional split between CU 160, DU 165, and RU 170 is flexible and may 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 functional split of a protocol stack may be employed between CU 160 and DU 165 such that CU 160 may support one or more layers of a protocol stack and DU 165 may support one or more different layers of a protocol stack. In some examples, CU 160 may host higher 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)). The CU 160 may be connected to one or more DUs 165 or RUs 170, and the one or more DUs 165 or RUs 170 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 the CU 160. Additionally or alternatively, a functional split of the protocol stack may be employed between the DUs 165 and RUs 170, such that the DUs 165 may support one or more layers of the protocol stack, and the RUs 170 may support one or more different layers of the protocol stack. The DUs 165 may support one or more different cells (e.g., via one or more RUs 170). In some cases, the functional split between CU 160 and DU 165 or between DU 165 and RU 170 may be within the protocol layer (e.g., some functions of the protocol layer may be performed by one of CU 160, DU 165, or RU 170, while other functions of the protocol layer are performed by different ones of CU 160, DU 165, or RU 170). CU 160 may be further functionally split into CU control plane (CU-CP) and CU user plane (CU-UP) functions. CU 160 may be connected to one or more DUs 165 via midhaul communication links 162 (e.g., F1, F1-c, F1-u), and DU 165 may be connected to one or more RUs 170 via fronthaul communication links 168 (e.g., open fronthaul (FH) interface). In some examples, midhaul communication link 162 or fronthaul communication link 168 may be implemented based on an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities 105 that communicate via such communication links.

[0058] In a wireless communication system (e.g., wireless communication system 100), 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 a core network 130). In some cases, in an IAB network, one or more network entities 105 (e.g., IAB nodes 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 DUs 165 or one or more RUs 170 may be controlled in part by one or more CUs 160 associated with a donor network entity 105 (e.g., a 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 nodes 104) via supported access and backhaul links (e.g., backhaul communication links 120). The IAB node 104 may include an IAB mobile terminal (IAB-MT) controlled (e.g., scheduled) by a coupled IAB donor's DU 165. The IAB-MT may include an independent set of antennas for relaying communications with the UE 115, or may share the same antennas of the IAB node 104 (e.g., of the RU 170) for access via the DU 165 of the IAB node 104 (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some examples, the 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 the IAB node 104) may be configured to operate according to the techniques described herein.

[0059] In the case where the techniques described herein are applied to the context of a decomposed RAN architecture, one or more components of the decomposed RAN architecture may be configured to support downlink preemption and uplink cancellation for a full-duplex system as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., a base station 140) may additionally or alternatively be performed by one or more components of the decomposed RAN architecture (e.g., an IAB node 104, a DU 165, a CU 160, a RU 170, a RIC 175, a SMO 180).

[0060] UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable term, where a "device" may also be referred to as a unit, a station, a terminal, or a client, etc. UE 115 may also include or may be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, UE 115 may include or may be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, etc., which may be implemented in various objects such as appliances or vehicles, meters, etc.

[0061] The UE 115 described herein may be capable of communicating with various types of devices, such as other UEs 115, which may sometimes act as relays, as well as network entities 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc. Figure 1 shown.

[0062] The UE 115 and the network entity 105 may 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" may refer to a collection of RF spectrum resources having a physical layer structure defined for supporting the communication link 125. For example, a carrier for the communication link 125 may include a portion of an RF spectrum band (e.g., a bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating carrier operations, user data, or other signaling. The wireless communication system 100 may support communications with the UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, the UE 115 may be configured to have multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may be used for both frequency division duplex (FDD) and time division duplex (TDD) component carriers. Communication between the network entity 105 and other devices may refer to communication between these devices and any part (e.g., entity, sub-entity) of the network entity 105. For example, the terms "send", "receive", or "communicate" when referring to the network entity 105 may refer to any part of the network entity 105 (e.g., base station 140, CU 160, DU 165, RU 170) of the RAN communicating with another device (e.g., directly or via one or more other network entities 105).

[0063] The communication link 125 shown in the wireless communication system 100 may include downlink transmissions (e.g., forward link transmissions) from the network entity 105 to the UE 115, uplink transmissions (e.g., return link transmissions) from the UE 115 to the network entity 105, or both, as well as other transmission configurations. A carrier may carry downlink communications or uplink communications (e.g., in FDD mode), or may be configured to carry downlink communications and uplink communications (e.g., in TDD mode).

[0064] A carrier may be associated with a particular bandwidth of the RF spectrum, and in some examples, the carrier bandwidth may be referred to as the "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of a set of bandwidths of carriers for a particular radio access technology (e.g., 1.4 megahertz (MHz), 3 MHz, 5 MHz, 10 MHz, 15 MHz, 20 MHz, 40 MHz, or 80 MHz). A device of the wireless communication system 100 (e.g., a network entity 105, a UE 115, or both) may have a hardware configuration that supports communications using a particular carrier bandwidth, or may be capable of being configured to support communications using one of the carrier bandwidths in the set of carrier bandwidths. In some examples, the wireless communication system 100 may include a network entity 105 or a UE 115 that supports concurrent communications using carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate using a portion (e.g., a subband, a BWP) or all of the carrier bandwidth.

[0065] The signal waveform transmitted via the carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, 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 the subcarrier spacing may be inversely related. The amount of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both), so that a relatively higher amount of resource elements (e.g., in the transmission duration) and a relatively higher order of the modulation scheme may correspond to a relatively higher communication rate. Wireless communication resources may refer to a combination of RF spectrum resources, time 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.

[0066] One or more parameter sets for a carrier may be supported, and the parameter sets may include subcarrier spacing (Δf) and cyclic prefixes. A carrier may be divided into one or more BWPs with the same or different parameter sets. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time, and communications of a UE 115 may be constrained to one or more active BWPs.

[0067] The time interval for the network entity 105 or the UE 115 may be expressed in multiples of a basic time unit, which may be, for example, a sampling period T s =1 / (Δf max ·N f ) seconds, where Δf max It can represent the supported subcarrier spacing, and N f The supported discrete Fourier transform (DFT) size may be indicated. Time intervals of the communication resources may be organized according to radio frames, each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0068] 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, the frame may be divided into subframes (e.g., in the time domain), and each subframe may be further divided into a certain 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 certain number of symbol periods (e.g., depending on the length of the cyclic prefix appended in front of each symbol period). In some wireless communication systems, the time slot may be further divided into 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., N f The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0069] A subframe, a time slot, a mini-time slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the amount of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in a burst of a shortened TTI (sTTI)).

[0070] Physical channels may be multiplexed using carriers for communication according to various techniques. Physical control channels and physical data channels may be multiplexed via downlink carriers for signaling, for example, using one or more of a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique. A control region (e.g., a control resource set (CORESET)) of a physical control channel may be defined by a set of symbol periods and may extend across a system bandwidth of a carrier or a subset of that system bandwidth. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, one or more UEs in UE115 may monitor or search a control region for control information according to one or more search space sets, and each search space set may include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. The aggregation level of a control channel candidate may 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 sets may include a common search space set configured for transmitting control information to multiple UEs 115 , and a UE-specific search space set for transmitting control information to a specific UE 115 .

[0071] In some examples, the network entities 105 (e.g., base stations 140, RUs 170) may be mobile and thus provide communication coverage for 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 provide coverage for respective coverage areas 110 using the same or different radio access technologies.

[0072] The wireless communication system 100 may support synchronous or asynchronous operation. For synchronous operation, the network entities 105 (e.g., base stations 140) may have similar frame timing, and transmissions from different network entities 105 may be approximately aligned in time. For asynchronous operation, the network entities 105 may have different frame timing, and in some examples, transmissions from different network entities 105 may not be aligned in time. The techniques described herein may be used for either synchronous operation or asynchronous operation.

[0073] Some UEs 115 may be configured to employ an operating mode that reduces power consumption, such as half-duplex communication (e.g., a mode that supports unidirectional communication via transmission or reception but does not transmit and receive concurrently). In some examples, half-duplex communication may be performed with a reduced peak rate. Other energy-saving techniques for UEs 115 include entering a power-saving deep sleep mode when not engaged in active communications, operating using limited bandwidth (e.g., according to narrowband communications), or a combination of these techniques. For example, some UEs 115 may be configured to operate using a narrowband protocol type that is associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs)) within a carrier, within a guard band of a carrier, or outside a carrier.

[0074] The wireless communication system 100 may be configured to support ultra-reliable communication or low-latency communication or various combinations thereof. For example, the 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 communication 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 commercial applications. The terms ultra-reliable, low-latency and ultra-reliable low-latency may be used interchangeably herein.

[0075] In some examples, a UE 115 may be configured to support communication directly with other UEs 115 via a device-to-device (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 that are performing D2D communication may be within a coverage area 110 of a network entity 105 (e.g., a base station 140, a RU 170), which may support aspects of such D2D communication configured by the network entity 105 (e.g., scheduled by the network entity). In some examples, one or more UEs 115 in such a group may be outside the coverage area 110 of the network entity 105, or may otherwise be unable or not configured to receive transmissions from the network entity 105. In some examples, a group of UEs 115 communicating via D2D communication may support a one-to-many (1:M) system, in which each UE 115 transmits to each of the other UEs 115 in the group. In some examples, network entity 105 may facilitate scheduling of resources for D2D communications. In some other examples, D2D communications may be conducted between UEs 115 without involving network entity 105.

[0076] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) for managing access and mobility and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) for routing packets or interconnecting to an external network. The control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by a network entity 105 (e.g., a base station 140) associated with the core network 130. User IP packets may be delivered via user plane entities, which may provide IP address allocation and other functions. The user plane entity may be connected to IP services 150 of one or more network operators. IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0077] The wireless communication system 100 may operate using one or more frequency bands that may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally speaking, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelength ranges from about 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 may be sufficient to penetrate structures so that macro cells provide services to UEs 115 located indoors. Communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) than communications using lower frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0078] The wireless communication system 100 may utilize licensed and unlicensed RF spectrum bands. For example, the wireless communication system 100 may employ license assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology using unlicensed bands such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating using unlicensed RF spectrum bands, devices such as network entities 105 and UEs 115 may employ carrier sensing for conflict detection and avoidance. In some examples, operations using unlicensed bands may be based on carrier aggregation configuration (e.g., LAA) in conjunction with component carriers operating using licensed bands. Operations using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, and the like.

[0079] The 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 technologies such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of the network entity 105 or UE 115 may be located in one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly such as an antenna tower. In some examples, antennas or antenna arrays associated with the network entity 105 may be located at different geographical locations. The network entity 105 may include an antenna array having a collection of multiple rows and columns of antenna ports that the network entity 105 can use to support beamforming for communications with the UE 115. Similarly, the UE 115 may include one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals sent via the antenna ports.

[0080] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a network entity 105, a UE 115) to shape or direct an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining signals conveyed via antenna elements of an antenna array so that some signals propagating along a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals conveyed via antenna elements may include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. Adjustments associated with each of these antenna elements may be defined by a set of beamforming weights associated with a particular direction (e.g., relative to the antenna array of the transmitting device or the receiving device or relative to some other direction).

[0081] The wireless communication system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, communications at the bearer or PDCP layer may be IP-based. The RLC layer may perform packet segmentation and reassembly to communicate via logical channels. The MAC layer may perform priority handling and multiplexing of logical channels into transport channels. The MAC layer may also implement error detection techniques, error correction techniques, or both to support retransmission to improve link efficiency. In the control plane, the RRC layer may provide the establishment, configuration, and maintenance of an RRC connection that supports radio bearers of user plane data between the UE 115 and the network entity 105 or the core network 130. The PHY layer may map transport channels to physical channels.

[0082] The wireless communication system 100 may support full-duplex communication (e.g., simultaneous transmission and reception). Some full-duplex communication schemes may include TDD bands without duplex enhancements for FDD bands. Other full-duplex communication schemes may support full-duplex operation at the network entity 105 and half-duplex operation at the UE 115. Other full-duplex communication schemes may support SBFD deployments, where non-overlapping frequency resources are used to perform concurrent downlink and uplink operations. Some wireless communication systems may support techniques for mitigating inter-gNB CLI and inter-UE CLI in full-duplex deployments. These systems may have RF requirements (and various other regulatory aspects) for self-interference, inter-subband CLI, inter-operator CLI, and FDD-like operation in TDD bands.

[0083] Some SBFD deployments that support non-overlapping full-duplex operation and dynamic (flexible) TDD may have regulations and RF requirements for adjacent channel coexistence with other RATs and communication schemes. These requirements may involve RF antennas, algorithms, antenna isolation, transmit intermodulation suppression (at the receiving device), filtering and digital interference suppression, etc. These regulations may affect full-duplex deployments in TDD non-paired spectrum.

[0084] The wireless communication system 100 may support various DCI formats, such as DCI format 2_1 and DCI format 2_4. DCI format 2_1 may be used to inform one or more UEs 115 of physical resource blocks (PRBs) and OFDM symbols, where the UE 115 may assume that no transmission is intended for the UE 115. One or more preemption indications may be sent via DCI format 2_1 with a cyclic redundancy check (CRC) scrambled by an interruption radio network temporary identifier (INT-RNTI). The size of DCI format 2_1 can be configured by a higher layer, up to 126 bits, with each preemption indication being 14 bits. If the UE 115 detects DCI format 2_1 of a serving cell from a configured serving cell set, the UE 115 may assume that there is no transmission to the UE 115 in the PRBs and symbols indicated by DCI format 2_1 (of the PRB set and symbol set from the last monitoring period). However, the preemption indication sent via DCI format 2_1 may not be applicable to SSB or PBCH transmissions.

[0085] DCI format 2_4 may be used to notify one or more UEs 115 of the PRBs and OFDM symbols in which uplink transmissions from UE 115 are canceled. One or more cancellation indications may be sent via DCI format 2_4 with a CRC scrambled by a cancellation indication radio network temporary identifier (CI-RNTI). The size of DCI format 2_4 may be configured by a high-level parameter dci_PayloadSizeforCI, up to 126 bits. The number of bits for each cancellation indication may be configured by a high-level parameter ci-PayloadSize. For a given UE 115, DCI format 2_4 may include at most one cancellation indication per uplink carrier. The cancellation indication sent via DCI format 2_4 applies to PUSCH transmissions and SRS transmissions on the serving cell of UE 115.

[0086] According to the techniques described herein, a UE 115 may receive an indication of an SBFD configuration for a serving cell of the UE 115. The SBFD configuration may indicate a first set of resources for downlink communication and a second set of resources for uplink communication. The first set of resources and the second set of resources may include non-overlapping frequency resources in the same time interval. The UE 115 may receive a control message indicating preemption of the first set of resources or cancellation of the second set of resources. Thus, the UE 115 may determine, based on the control message and the SBFD configuration of the cell, that downlink transmission in at least a portion of the first set of resources is preempted or uplink transmission in at least a portion of the second set of resources is canceled.

[0087] Various aspects of the wireless communication system 100 may be implemented to achieve one or more of the following advantages. Figure 1 Techniques are described that may reduce CLI caused by full-duplex communications at one or more network entities 105. For example, a first network entity 105 with SBFD capability may use one or more cancellation indications (sent via DCI format 2_4) to cancel one or more PUCCH or PRACH transmissions that overlap with downlink transmissions from a second network entity, thereby reducing the likelihood that the downlink transmissions (from the second network entity) interfere with reception of the PUCCH or PRACH transmissions at the first network entity.

[0088] Figure 2 An example of a wireless communication system 200 that supports downlink preemption and uplink cancellation for a full-duplex system according to one or more aspects of the present disclosure is illustrated. The wireless communication system 200 may implement aspects of the wireless communication system 100 or be implemented by these aspects. For example, the wireless communication system 200 may include a network entity 105-a, a network entity 105-b, a UE 115-a, a UE 115-b, and a UE 115-c, which may be reference Figure 1In the wireless communication system 200, the network entity 105 can use the preemption indication (sent through DCI format 2_1), the cancellation indication (sent through DCI format 2_4) and the silent mode (sent through UE-specific signaling or group common signaling) to mitigate CLI.

[0089] exist Figure 2 In an example of , one or more of UE 115 or network entity 105 may support full-duplex communications. For example, network entity 105-a may send downlink message 205-a to UE 115-a while simultaneously, receiving uplink message 210-b from UE 115-b. Similarly, network entity 105-b may receive uplink message 210-d from UE 115-c while concurrently sending downlink message 205-c to UE 115-b. However, in some cases, these full-duplex communications may result in self-interference or CLI. For example, sending uplink message 210-a to network entity 105-a while receiving downlink message 205-a from network entity 105-a may result in self-interference at UE 115-a. Similarly, a downlink message 205-b from network entity 105-a may interfere with reception of an uplink message 210-c (from UE 115-b) at network entity 105-b, and a downlink message 205-d from network entity 105-b may interfere with reception of an uplink message 210-b (from UE 115-b) at network entity 105-a.

[0090] The wireless communication system 200 may support different DCI formats. However, some of these DCI formats (2_1 and 2_4) may be limited to full downlink and uplink muting scenarios. For example, DCI format 2_4 may only be applicable to PUSCH transmission and SRS transmission. That is, DCI format 2_4 may not be applicable to random access timing and PUCCH transmission. Similarly, DCI format 2_1 may not be applicable to SSB transmission. In addition, DCI formats 2_1 and 2_4 are group common DCI formats that may have limited reliability in some cases. When the network entity 105 silences the downlink transmission (via one or more preemption indications), the UE 115 may not expect any downlink transmission (including SSB transmission) at the indicated resources. Similarly, when the network entity 105 silences the uplink transmission from the UE 115 (via one or more cancellation indications), the UE 115 may suppress all uplink transmissions on the indicated resources.

[0091] refer to Figure 2The described techniques and operations can enhance downlink preemption indication and uplink cancellation indication to enable comprehensive downlink and uplink muting for downlink and uplink signals and channels with different priorities. The described techniques can also support the use of UE-specific L1 signaling to indicate muting mode and improve the reliability of detection (compared to group common DCI). If both uplink cancellation indication and UE-internal priority indicator are configured for one or more of UE 115, RRC parameters can be used to configure different behaviors for different scenarios. If the parameter is provided to UE 115, the uplink cancellation indication can be applicable to uplink transmissions indicated or configured with a low priority level. Otherwise, the uplink cancellation indication can be applicable to all uplink transmissions (regardless of the priority level).

[0092] Various aspects of the wireless communication system 200 may be implemented to achieve one or more of the following advantages. Figure 2 Techniques are described that may reduce CLI caused by full-duplex communications at network entity 105. For example, network entity 105-a (e.g., a gNB with SBFD capability) may use one or more preemption indications (sent via DCI format 2_1) to preempt one or more SSB or PBCH transmissions from network entity 105-a that overlap with uplink transmissions to network entity 105-b, thereby reducing the likelihood that the SSB or PBCH transmissions (from network entity 105-a) interfere with reception of the uplink transmissions at network entity 105-b.

[0093] Figure 3 An example of a resource map 300 supporting downlink preemption and uplink cancellation for a full-duplex system according to one or more aspects of the present disclosure is illustrated. The resource map 300 may implement aspects of the wireless communication system 100 or the wireless communication system 200, or may be implemented by aspects of the wireless communication system 100 or the wireless communication system 200. For example, the communication scheme 300 may be implemented by a UE or a network entity (which may be a reference Figure 1 and Figure 2 The resource diagram 300 illustrates various full-duplex communication schemes and deployment scenarios.

[0094] The full-duplex communication scheme 320 may be an example of a SBFD deployment scenario with non-overlapping uplink and downlink subbands. The full-duplex communication scheme 325 may be an example of a full-duplex deployment scenario with partially overlapping uplink and downlink subbands. The full-duplex communication scheme 330 may be an example of a SFFD deployment scenario with fully overlapping uplink and downlink subbands. In some examples, the full-duplex communication scheme 320 may correspond to a deployment scenario with a full-duplex gNB and a half-duplex UE, and the full-duplex communication scheme 325 may correspond to a deployment scenario with a full-duplex gNB and a UE. In some examples, the full-duplex communication scheme 330 may be applicable to a deployment scenario with a half-duplex gNB, a half-duplex multiple transmit-receive point (mTRP), a UE with SBFD capabilities, or any combination thereof.

[0095] exist Figure 3 In the example of , a first network entity (SBFD gNB) enabled with SBFD and a second network entity (TDD gNB) enabled with TDD may be configured to have different uplink and downlink frequency subbands. For example, the downlink resources 310-a of the SBFD gNB may overlap with the uplink resources 305-a of the TDD gNB. To mitigate the inter-gNB CLI caused by this overlap, the TDD gNB may silence the uplink resources 305-a, as illustrated in resource diagram 300. Similarly, if the downlink resources 310-b of the TDD gNB overlap with the uplink resources 305-c of the SBFD gNB, the TDD gNB may silence the downlink resources 310-b to reduce the likelihood that downlink transmissions from the TDD gNB interfere with uplink reception at the SBFD gNB.

[0096] Aspects of the present disclosure support enhancements to DCI format 2_4. For example, when SBFD (for the serving cell of the UE) is configured, the cancellation indication sent via DCI format 2_4 may be applicable to PUCCH transmissions and PRACH transmissions. In some examples, the cancellation indication may be applicable to all uplink signals and channels (regardless of whether uplinkCancellationPriority is configured). In other examples, if uplinkCancellationPriority is configured, higher priority signals and channels may be sent with higher power to enable uplink reception at the victim gNB (equivalently referred to as a network entity) that is experiencing inter-gNB CLI. The cancellation indication may be applicable to RRC-configured uplink transmissions as well as dynamically scheduled uplink transmissions.

[0097] If SBFD communication is configured for the serving cell of the UE, the cancellation indication sent by DCI format 2_4 may be applicable to PUSCH transmission and SRS transmission. Otherwise, the cancellation indication may be applicable to all uplink signals, channels and priorities. In some examples, if the uplink transmission 335 partially overlaps with the silent uplink frequency resources, the UE may completely discard (suppress, avoid sending) the uplink transmission 335. In other examples, if the uplink transmission 335 is an SRS transmission, the UE may truncate the uplink transmission 335 at the cancelled resource. If the uplink transmission 335 is a PUSCH transmission, the UE may rate match the uplink transmission 335 around the cancelled resource. Additionally or alternatively, the UE may apply a transmit power boost to the uplink transmission 335 by increasing the power spectral density (PSD) of the frequency resources used for the uplink transmission 335. In some examples, the PSD boost may be selectively applied to frequency resources overlapping with the cancelled resources.

[0098] Aspects of the present disclosure also support enhancements to DCI format 2_1. Specifically, when SBFD is configured for the serving cell of the UE, DCI format 2_1 may be used to silence or preempt all downlink signals and channels (including SSB transmissions). For example, the TDD gNB may discard (silence, suppress) SSB transmission 340 to mitigate inter-gNB CLI in the uplink subband of the SBFD gNB. If the UE detects DCI format 2_1 for the serving cell (from the configured serving cell set), the UE may assume that there is no transmission to the UE in the PRBs and OFDM symbols indicated by DCI format 2_1 (of the PRB set and symbol set from the previous monitoring period). When SBFD communication is configured for the serving cell or a neighboring cell, the indication of DCI format 2_1 may apply to SSB transmissions and PBCH transmissions.

[0099] The resource map 300 may also support techniques for reducing inter-gNB CLI by using UE-specific signaling (L1 or L2 signaling) to indicate a muting pattern that specifies time and frequency resources in which uplink transmissions are canceled or downlink transmissions are not expected. For each set of time and frequency resources indicated by the muting pattern, a bit may indicate whether uplink transmissions are canceled or downlink transmissions are not expected. If the indicated symbol is designated as a downlink symbol (via RRC signaling), the UE may not expect to receive a downlink transmission in the indicated symbol. Similarly, if the indicated symbol is configured as an uplink symbol, the UE may cancel uplink transmissions in the indicated symbol. The muting pattern may be applicable to the UE's serving cell.

[0100] When SBFD communication is enabled (configured) for the serving cell of the UE, the silence mode (indicated by L1 or L2 signaling) may indicate subband blanking. When the downlink subband is blanked (silent), the UE may not expect to receive downlink transmissions in the downlink subband for the indicated time resources (OFDM symbols). However, in some examples, the UE may be dynamically scheduled to send uplink messages in the blanked downlink subband. In other words, the silence mode may optionally convert the downlink subband to an uplink subband. When the uplink subband is blanked, the UE may cancel all uplink transmissions in the uplink subband for the indicated time resources. In some examples, the UE may be dynamically scheduled to receive downlink transmissions in the silent uplink subband (e.g., the silence mode may optionally convert the uplink subband to a downlink subband).

[0101] Figure 4 An example of a resource map 400 supporting downlink preemption and uplink cancellation for a full-duplex system according to one or more aspects of the present disclosure is illustrated. The resource map 400 may implement aspects of the wireless communication system 100 or the wireless communication system 200, or may be implemented by aspects of the wireless communication system 100 or the wireless communication system 200. For example, the communication scheme 400 may be implemented by a UE or a network entity (which may be a reference Figure 1 and Figure 2 Resource diagram 400 illustrates various communication schemes for supporting coexistence between a first network entity (SBFD gNB) with SBFD communication enabled and a second network entity (TDD gNB) with TDD configured.

[0102] In some examples, if the SBFD gNB and TDD gNB are configured with different uplink and downlink subbands, downlink transmissions from the SBFD gNB may cause inter-gNB CLI at the TDD gNB (or vice versa). For example, if the downlink subband of the TDD gNB overlaps with the uplink subband of the SBFD gNB, then downlink transmissions from the TDD gNB (aggressor gNB) may interfere with uplink reception at the SBFD gNB (victim gNB). To mitigate this inter-gNB CLI, the TDD gNB may mute downlink frequency resources that overlap with the uplink subband resources of the SBFD gNB. Similarly, if downlink transmissions from the SBFD gNB (aggressor gNB) interfere with uplink reception at the TDD gNB (victim gNB), the TDD gNB may mute uplink frequency resources that overlap with the downlink subband frequency resources of the SBFD gNB.

[0103] As an example, if the uplink resources 405-a of the TDD gNB partially overlap with the downlink resources 410-a of the SBFD gNB, the TDD gNB may silence (cancel) the uplink resources 415-a overlapping with the downlink resources 410-a. Alternatively, the SBFD gNB may silence (preempt) the downlink resources 415-b overlapping with the uplink resources 405-a. Similarly, if the downlink resources 410-b of the TDD gNB partially overlap with the uplink resources 405-b of the SBFD gNB, the TDD gNB may silence (preempt) the downlink resources 415-c overlapping with the uplink resources 405-b. Alternatively, the SBFD gNB may silence (cancel) the uplink resources 415-d overlapping with the downlink resources 410-b.

[0104] For example, if both uplink resources 405-c and uplink resources 405-d of the SBFD gNB partially overlap with downlink resources 410-c of the TDD gNB, the SBFD gNB may mute (cancel) uplink resources 415-e and uplink resources 415-f that overlap with downlink resources 410-c of the TDD gNB. Similarly, if both downlink resources 410-d and downlink resources 410-e of the SBFD gNB partially overlap with uplink resources 405-e of the TDD gNB, the SBFD gNB may mute (preempt) downlink resources 415-g and downlink resources 415-h that overlap with uplink resources 405-e of the TDD gNB.

[0105] Figure 5 An example of a process flow 500 for supporting downlink preemption and uplink cancellation for a full-duplex system according to one or more aspects of the present disclosure is illustrated. The process flow 500 may implement or be implemented by aspects of the wireless communication system 100 or the wireless communication system 200. For example, the process flow 500 may include the UE 115-d and the network entity 105-c, which may be reference Figure 1 and Figure 2 Examples of corresponding devices described. In the following description of process flow 500, operations between UE 115-d and network entity 105-c may be added, omitted, or performed in a different order (relative to the exemplary order shown).

[0106] At 505, UE 115-d may receive an indication of an SBFD configuration for a cell serving UE 115-d (e.g., a cell of network entity 105-c). The SBFD configuration may indicate a first set of resources for downlink communication and a second set of resources for uplink communication. The first set of resources and the second set of resources may include non-overlapping frequency resources in the same time slot. At 510, network entity 105-c may send a control message indicating the preemption of the first set of resources or the cancellation of the second set of resources. The control message may include MAC-CE, DCI (format 2_1 or 2_4), UE-specific signaling, group common signaling, or some combination thereof. In some examples, the control message may indicate a silent mode for one or both of the first set of resources or the second set of resources.

[0107] At 515, UE 115-d may determine that the control message is applicable to PUCCH transmission, PRACH transmission, SRS transmission, PUSCH transmission, or a combination thereof based on the SBFD configuration of the cell serving UE 115-d and the format of the control message (DCI format 2_4). Additionally or alternatively, UE 115-d may determine that the control message is applicable to SSB transmission and PBCH transmission based on the SBFD configuration of the cell serving UE 115-d and the format of the control message (DCI format 2_1). If the SBFD configuration indicates that SBFD communication is enabled for network entity 105-c, the control message may be applicable to all uplink transmission types, channels, and priority levels or all downlink transmission types, channels, and priority levels (depending on the format of the control message).

[0108] At 520, UE 115-d may determine that downlink transmission in at least a portion of the first set of resources is preempted or uplink transmission in at least a portion of the second set of resources is canceled based on the control message and the SBFD configuration of the cell serving UE 115-d. For example, UE 115-d may determine to suppress, truncate, or rate match uplink transmissions overlapping with the second set of resources. Additionally or alternatively, UE 115-d may use a higher PSD for uplink transmissions overlapping (in frequency) with the second set of resources. In some examples, UE 115-d may determine that downlink transmission is not expected in a downlink subband based on a blanking indication in a control message. In other examples, UE 115-d may determine that uplink transmission is canceled in an uplink subband based on a blanking indication in a control message.

[0109] In some examples, UE 115-d may send an uplink message to network entity 105-c at 525. For example, UE 115-d may send an uplink message via a second set of resources based on an uplink cancellation priority parameter (uplinkCancellationPriority) indicated by the SBFD configuration of the cell and a priority level of the uplink message. In some examples, UE 115-d may determine a transmit power for the uplink message based on the priority level of the uplink message. In some examples, network entity 105-c may dynamically schedule uplink messages on resources overlapping with a muted (blanked) downlink subband. At 530, network entity 105-c may send dynamically scheduled downlink messages on resources overlapping with a muted (blanked) uplink subband.

[0110] Various aspects of process flow 500 may be implemented to achieve one or more of the following advantages. Figure 5 Techniques are described to reduce CLI caused by full-duplex communications at a network entity 105-c. For example, a network entity 105-c (e.g., a gNB enabled for SBFD communications) may use one or more cancel indications (sent via DCI format 2_4) or muting patterns (sent via UE-specific signaling or group-common signaling) to cancel one or more PUSCH or SRS transmissions (from UE 115-d) that overlap with a downlink transmission from a second network entity, thereby reducing the probability that the downlink transmission causes CLI at the network entity 105-c.

[0111] Figure 6 A block diagram 600 of a device 605 supporting downlink preemption and uplink cancellation for a full-duplex system according to one or more aspects of the present disclosure is shown.

The information may be communicated to other components of device 605. Receiver 610 may utilize a single antenna or a collection of multiple antennas.

[0113] The transmitter 615 may provide means for transmitting signals generated by other components of the device 605. For example, the transmitter 615 may transmit information such as packets associated with various information channels (e.g., control channels, data channels, information channels related to downlink preemption and uplink cancellation for full-duplex systems), user data, control information, or any combination thereof. In some examples, the transmitter 615 may be co-located with the receiver 610 in a transceiver module. The transmitter 615 may utilize a single antenna or a collection of multiple antennas.

[0114] The communication manager 620, the receiver 610, the transmitter 615, or various combinations thereof, or various components thereof may be examples of means for performing various aspects of downlink preemption and uplink cancellation for full-duplex systems as described herein. For example, the communication manager 620, the receiver 610, the transmitter 615, or various combinations thereof, or components thereof may support methods for performing one or more of the functions described herein.

[0115] In some examples, the communication manager 620, the receiver 610, the transmitter 615, or various combinations or components thereof may be implemented in hardware (e.g., in a communication management circuit). The hardware may include a processor, a digital signal processor (DSP), a central processing unit (CPU), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device, a microcontroller, discrete gate or transistor logic, discrete hardware components, or any combination thereof that is configured to or otherwise supports components for performing the functions described herein. In some examples, the processor and a memory coupled to the processor may be configured to perform one or more of the functions described herein (e.g., by executing instructions stored in the memory by the processor).

[0116] Additionally or alternatively, in some examples, the communication manager 620, the receiver 610, the transmitter 615, or various combinations or components thereof may be implemented in code executed by a processor (e.g., as communication management software or firmware). If implemented in code executed by a processor, the functionality of the communication manager 620, the receiver 610, the transmitter 615, or various combinations or components thereof may be performed by a general purpose processor (e.g., configured as or otherwise supporting components for performing the functions described in the present disclosure), a DSP, a CPU, an ASIC, an FPGA, a microcontroller, or any combination of these or other programmable logic devices.

[0117] In some examples, communication manager 620 may be configured to perform various operations (e.g., receive, obtain, monitor, output, transmit) using or otherwise cooperating with receiver 610, transmitter 615, or both. For example, communication manager 620 may receive information from receiver 610, transmit information to transmitter 615, or be integrated in conjunction with receiver 610, transmitter 615, or both to obtain information, output information, or perform various other operations as described herein.

[0118] According to examples disclosed herein, the communication manager 620 may support wireless communications at the device 605. For example, the communication manager 620 may be configured to or otherwise support a component for receiving an indication of an SBFD configuration of a cell serving the device 605, the SBFD configuration indicating a first set of resources for downlink communications and a second set of resources for uplink communications, wherein the first set of resources and the second set of resources include non-overlapping frequency resources in the same time interval. The communication manager 620 may be configured to or otherwise support a component for receiving a control message indicating preemption of the first set of resources or cancellation of the second set of resources. The communication manager 620 may be configured to or otherwise support a component for determining, based on the control message and the SBFD configuration of the cell, that downlink transmission in at least a portion of the first set of resources is preempted or uplink transmission in at least a portion of the second set of resources is canceled.

[0119] By including or configuring the communication manager 620 according to examples as described herein, the device 605 (e.g., a processor controlling or otherwise coupled with the receiver 610, the transmitter 615, the communication manager 620, or a combination thereof) can support techniques for reducing power consumption by reducing the number of retransmissions performed by the device 605. For example, the techniques described herein can reduce CLI at a network entity communicating with the device 605, which can increase the likelihood that an uplink message from the device 605 is successfully received by the network entity. As a result, the device 605 can retransmit the uplink message less times, which can result in reduced power consumption at the device 605, among other benefits.

[0142] Fig. 9 A diagram of a system 900 including a device 905 that supports downlink preemption and uplink cancellation for a full-duplex system according to one or more aspects of the present disclosure is shown. The device 905 may be an example of a device 605, a device 705, or a UE 115 as described herein, or include components thereof. The device 905 may communicate (e.g., wirelessly) with one or more network entities 105, one or more UEs 115, or any combination thereof. The device 905 may include components for two-way voice and data communications, including components for sending and receiving communications, such as a communication manager 920, an input / output (I / O) controller 910, a transceiver 915, an antenna 925, a memory 930, a code 935, and a processor 940. These components may be electronically communicated or otherwise coupled (e.g., operatively, communicatively, functionally, electronically, electrically) via one or more buses (e.g., a bus 945).

[0143] I / O controller 910 may manage input and output signals for device 905. I / O controller 910 may also manage peripheral devices that are not integrated into device 905. In some cases, I / O controller 910 may represent a physical connection or port to an external peripheral device. In some cases, I / O controller 910 may utilize an operating system, such as or another known operating system. Additionally or alternatively, I / O controller 910 may represent or interact with a modem, keyboard, mouse, touch screen, or similar device. In some cases, I / O controller 910 may be implemented as part of a processor (such as processor 940). In some cases, a user may interact with device 905 via I / O controller 910 or via hardware components controlled by I / O controller 910.

The memory 930 may store computer-readable, computer-executable code 935 including instructions that, when executed by the processor 940, cause the device 905 to perform various functions described herein. The code 935 may be stored in a non-transitory computer-readable medium such as a system memory or another type of memory. In some cases, the code 935 may not be directly executable by the processor 940, but may (for example, when compiled and executed) cause the computer to perform the functions described herein. In some cases, the memory 930 may also include, among other things, a basic I / O system (BIOS) that may control basic hardware or software operations, such as interaction with peripheral components or devices.

[0146] The processor 940 may include an intelligent hardware device (e.g., a general-purpose processor, a DSP, a CPU, a microcontroller, an ASIC, an FPGA, a programmable logic device, a discrete gate or transistor logic component, a discrete hardware component, or any combination thereof). In some cases, the processor 940 may be configured to operate a memory array using a memory controller. In some other cases, the memory controller may be integrated into the processor 940. The processor 940 may be configured to execute computer-readable instructions stored in a memory (e.g., a memory 930) to enable the device 905 to perform various functions (e.g., various functions or tasks supporting downlink preemption and uplink cancellation for a full-duplex system). For example, the device 905 or a component of the device 905 may include a processor 940 and a memory 930 coupled to or coupled to the processor 940, and the processor 940 and the memory 930 are configured to perform the various functions described herein.

[0147] According to examples disclosed herein, the communication manager 920 may support wireless communications at the device 905. For example, the communication manager 920 may be configured to or otherwise support a component for receiving an indication of an SBFD configuration of a cell serving the device 905, the SBFD configuration indicating a first set of resources for downlink communications and a second set of resources for uplink communications, wherein the first set of resources and the second set of resources include non-overlapping frequency resources in the same time interval. The communication manager 920 may be configured to or otherwise support a component for receiving a control message indicating preemption of the first set of resources or cancellation of the second set of resources. The communication manager 920 may be configured to or otherwise support a component for determining, based on the control message and the SBFD configuration of the cell, that downlink transmission in at least a portion of the first set of resources is preempted or uplink transmission in at least a portion of the second set of resources is canceled.

[0148] By including or configuring a communication manager 920 according to an example as described herein, the device 905 may support techniques for reducing inter-gNB CLI in a full-duplex wireless communication system. For example, a network entity that enables SBFD may use one or more preemption indications (sent via DCI format 2_1), cancel indications (sent via DCI format 2_4), or muting patterns (indicated by L1 or L2 signaling) to mute one or more PUCCH, PUSCH, PRACH, or SRS transmissions from the device 905, thereby reducing the probability that such transmissions cause CLI at other communication devices.

[0149] In some examples, the communication manager 920 may be configured to perform various operations (e.g., receive, monitor, transmit) using or otherwise cooperating with the transceiver 915, one or more antennas 925, or any combination thereof. Although the communication manager 920 is illustrated as a separate component, in some examples, one or more functions described with reference to the communication manager 920 may be supported or performed by the processor 940, the memory 930, the code 935, or any combination thereof. For example, the code 935 may include instructions that are executable by the processor 940 to cause the device 905 to perform various aspects of downlink preemption and uplink cancellation for a full-duplex system as described herein, or the processor 940 and the memory 930 may be otherwise configured to perform or support such operations.

Additionally or alternatively, the transmitter 1015 may support outputting information by sending signals via one or more wired (e.g., electrical, optical) interfaces, wireless interfaces, or any combination thereof. In some examples, the transmitter 1015 and the receiver 1010 may be co-located in a transceiver, which may include a modem or be coupled to a modem.

[0153] The communication manager 1020, the receiver 1010, the transmitter 1015, or various combinations thereof, or various components thereof may be examples of means for performing various aspects of downlink preemption and uplink cancellation for full-duplex systems as described herein. For example, the communication manager 1020, the receiver 1010, the transmitter 1015, or various combinations thereof, or components thereof may support methods for performing one or more of the functions described herein.

[0154] In some examples, the communication manager 1020, the receiver 1010, the transmitter 1015, or various combinations or components thereof may be implemented in hardware (e.g., in a communication management circuit).

[0155] Additionally or alternatively, in some examples, the communication manager 1020, the receiver 1010, the transmitter 1015, or various combinations or components thereof may be implemented in code executed by a processor (e.g., as communication management software or firmware). If implemented in code executed by a processor, the functionality of the communication manager 1020, the receiver 1010, the transmitter 1015, or various combinations or components thereof may be performed by a general purpose processor (e.g., configured as or otherwise supporting components for performing the functions described in the present disclosure), a DSP, a CPU, an ASIC, an FPGA, a microcontroller, or any combination of these or other programmable logic devices.

[0156] In some examples, communication manager 1020 may be configured to perform various operations (e.g., receive, obtain, monitor, output, send) using or otherwise cooperating with receiver 1010, transmitter 1015, or both. For example, communication manager 1020 may receive information from receiver 1010, transmit information to transmitter 1015, or be integrated in conjunction with receiver 1010, transmitter 1015, or both to obtain information, output information, or perform various other operations as described herein.

[0158] By including or configuring a communication manager 1020 according to examples as described herein, a device 1005 (e.g., a processor controlling or otherwise coupled to a receiver 1010, a transmitter 1015, a communication manager 1020, or a combination thereof) can support techniques for reducing power consumption and improving communication reliability. For example, the described techniques can reduce CLI at the device 1005, which can increase the likelihood that the device 1005 successfully receives uplink transmissions from other communication devices. As a result, the device 1005 can request fewer retransmissions, which can enable the device to remain in a sleep mode (e.g., a low power state) for a longer duration.

[0169] The transceiver 1310 may support bidirectional communication via a wired link, a wireless link, or both as described herein. In some examples, the transceiver 1310 may include a wired transceiver and may communicate bidirectionally with another wired transceiver. Additionally or alternatively, in some examples, the transceiver 1310 may include a wireless transceiver and may communicate bidirectionally with another wireless transceiver.

In some cases, code 1330 may not be directly executable by processor 1335, but may (e.g., when compiled and executed) cause a computer to perform the functions described herein. In some cases, memory 1325 may also include, among other things, a BIOS that may control basic hardware or software operations, such as interaction with peripheral components or devices.

[0171] The processor 1335 may include an intelligent hardware device (e.g., a general-purpose processor, a DSP, an ASIC, a CPU, an FPGA, a microcontroller, a programmable logic device, a discrete gate or transistor logic, a discrete hardware component, or any combination thereof). In some cases, the processor 1335 may be configured to operate a memory array using a memory controller. In some other cases, the memory controller may be integrated into the processor 1335. The processor 1335 may be configured to execute computer-readable instructions stored in a memory (e.g., a memory 1325) to enable the device 1305 to perform various functions (e.g., various functions or tasks supporting downlink preemption and uplink cancellation for a full-duplex system). For example, the device 1305 or a component of the device 1305 may include a processor 1335 and a memory 1325 coupled to the processor 1335, and the processor 1335 and the memory 1325 are configured to perform the various functions described herein.

[0172] Processor 1335 may be an example of a cloud computing platform (e.g., one or more physical nodes and supporting software such as an operating system, a virtual machine, or a container instance) that may host functions for performing functions of device 1305 (e.g., by executing code 1330). Processor 1335 may be any one or more suitable processors capable of executing scripts or instructions of one or more software programs stored in device 1305 (such as within memory 1325). In some specific implementations, processor 1335 may be a component of a processing system. A processing system may generally refer to a system or a series of machines or components that receive inputs and process these inputs to produce a set of outputs (which may be passed to other systems or components (e.g., device 1305)). For example, a processing system of device 1305 may refer to a system including various other components or subcomponents of device 1305, such as processor 1335, or transceiver 1310, or communication manager 1320, or other components or combinations of components of device 1305.

[0173] The processing system of device 1305 can be docked with other components of device 1305, and can process information (such as input or signal) received from other components or output information to other components. For example, the chip or modem of device 1305 may include a processing system and one or more interfaces for outputting information or for obtaining information or both.

In some specific implementations, the one or more interfaces may refer to an interface between the processing system of the chip or modem and a transmitter, so that the device 1305 can send information output from the chip or modem. Additionally or alternatively, in some specific implementations, the one or more interfaces may refer to an interface between the processing system of the chip or modem and a receiver, so that the device 1305 can obtain information or signal input, and the information can be passed to the processing system. Those of ordinary skill in the art will easily recognize that the first interface can also obtain information or signal input, and the second interface can also output information or signal output.

[0174] In some examples, bus 1340 may support communications of protocol layers (e.g., within a protocol layer) of a protocol stack. In some examples, bus 1340 may support communications associated with logical channels of a protocol stack (e.g., between protocol layers of a protocol stack), which may include communications performed within components of device 1305, or communications performed between different components of device 1305 that may be co-located or may be located in different locations (e.g., where device 1305 may refer to a system in which one or more of communication manager 1320, transceiver 1310, memory 1325, code 1330, and processor 1335 may be located in one component of different components or divided between different components).

[0175] In some examples, communication manager 1320 may manage aspects of communications with core network 130 (e.g., via one or more wired or wireless backhaul links). For example, communication manager 1320 may manage delivery of data communications for client devices such as one or more UEs 115. In some examples, communication manager 1320 may manage communications with other network entities 105 and may include a controller or scheduler for controlling communications with UE 115 in coordination with other network entities 105.

[0176] According to the examples disclosed herein, the communication manager 1320 may support wireless communication at the device 1305. For example, the communication manager 1320 may be configured to or otherwise support a component for sending an indication of an SBFD configuration of a cell serving the UE, the SBFD configuration indicating a first set of resources for downlink communication and a second set of resources for uplink communication, wherein the first set of resources and the second set of resources include non-overlapping frequency resources in the same time interval. The communication manager 1320 may be configured to or otherwise support a component for sending a control message indicating preemption of the first set of resources or cancellation of the second set of resources, the preemption indicating preempting downlink transmission in at least a portion of the first set of resources according to the SBFD configuration of the cell, and the cancellation indicating canceling uplink transmission in at least a portion of the second set of resources according to the SBFD configuration of the cell.

[0177] By including or configuring the communication manager 1320 according to examples as described herein, the device 1305 may support techniques for reducing inter-gNB CLI caused by the device 1305. For example, the device 1305 (SBFD-enabled network entity) may use one or more preemption indications (sent via DCI format 2_1) or muting patterns (indicated by UE-specific signaling or group-common signaling) to preempt one or more SSB or PBCH transmissions from the device 1305 that may potentially cause inter-gNB CLI at the second network entity, thereby increasing the likelihood of successful uplink reception at the second network entity.

[0178] In some examples, the communication manager 1320 may be configured to perform various operations (e.g., receive, obtain, monitor, output, transmit) using or otherwise cooperating with the transceiver 1310, one or more antennas 1315 (e.g., where applicable), or any combination thereof. Although the communication manager 1320 is illustrated as a separate component, in some examples, one or more functions described with reference to the communication manager 1320 may be supported or performed by the transceiver 1310, the processor 1335, the memory 1325, the code 1330, or any combination thereof. For example, the code 1330 may include instructions that are executable by the processor 1335 to cause the device 1305 to perform various aspects of downlink preemption and uplink cancellation for a full-duplex system as described herein, or the processor 1335 and the memory 1325 may be otherwise configured to perform or support such operations.

The operations of the method 1500 may be implemented by a UE or a component thereof. For example, the operations of the method 1500 may be implemented by a UE as described in reference to Figures 1 to 9 The UE 115 described herein may be executed.
