Techniques for signaling in sub-band full duplex operation

Abstract

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may adjust signaling in a slot configured for subband full duplex (SBFD) communication based on receiving scheduling information indicating a signal. In a first option, a corresponding sub-band may be expanded to include the signal. If there is a remaining frequency resource, the remaining opposite direction sub-band may be used for the corresponding communication. In a second option, the remaining frequency resources of the opposite direction sub-band are available for communication in the same direction as the signal. In a third option, the signal may be cancelled, or portions of the signal located outside the corresponding sub-band may be cancelled. In a fourth option, the signal may be regarded as an error. In some examples, the option may be configured based on a type of the signal or based on a priority level of the signal.

[0002] This patent application claims priority to U.S. patent application No. 17 / 886,421, entitled “TECHNIQUES FORSIGNALING IN SUBBAND ​​FULL-DUPLEX OPERATION,” filed by Zhang et al. on August 11, 2022, which is assigned to the assignee of this application and is expressly incorporated herein by reference. Technical Field

[0003] The following relates to wireless communications, including techniques for signaling in sub-band full-duplex operation. Background Art

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, 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). Summary of the invention

[0005] The described technology relates to improved methods, systems, devices and apparatuses for supporting technology for signaling in sub-band full-duplex (SBFD) operation. For example, the described technology provides a method that enables a user equipment (UE) to adjust the signaling in a time slot configured for SBFD communication based on the scheduling information received indicating the configured signal in the time slot. In a first option, the corresponding subband may be extended to include the configured signal. If there are remaining frequency resources, the remaining opposite direction subbands can still be used for corresponding communication. In a second option, the remaining frequency resources of the opposite direction subband can be used for communication in the same direction as the configured signal. In a third option, the configured signal can be canceled, or the portion of the configured signal located outside the corresponding subband can be canceled. In a fourth option, the configured signal can be considered an error. For example, if the signal is a downlink signal, the UE can skip receiving the configured signal and send feedback (e.g., negative acknowledgment (NACK) feedback). In some examples, the option can be configured based on the type of the signal or based on the priority level of the signal. The network entity can indicate to the UE priority-based rules for how to convey the configured signal.

[0053] In some cases, a network entity may implement a sub-band full-duplex (SBFD) communication scheme, in which a first one or more sub-bands in a time slot may be reserved for communication in a first direction (e.g., downlink), and a second one or more sub-bands in a time slot may be reserved for communication in a second direction (e.g., uplink) that is different from the first direction. The effect of the SBFD scheme may be to increase the duty cycle of the communication, which may, for example, reduce the latency of uplink communications from a user equipment (UE). However, in some cases, a configured signal (e.g., a downlink signal or an uplink signal) may not be restricted to the corresponding reserved sub-bands.

[0054] According to the techniques described herein, a UE may adjust signaling in a time slot configured for SBFD communication based on scheduling information received indicating a configured signal in a time slot. In a first option, the corresponding subband may be extended to include a configured signal. If there are remaining frequency resources, the remaining opposite direction subband may still be used for corresponding communication. In a second option, the remaining frequency resources of the opposite direction subband may be used for communication in the same direction as the configured signal. In a third option, the configured signal may be canceled, or a portion of the configured signal located outside the corresponding subband may be canceled. In a fourth option, the configured signal may be considered an error. For example, if the signal is a downlink signal, the UE may skip receiving the configured signal and send feedback (e.g., negative acknowledgment (NACK) feedback). In some examples, the options may be configured based on the type of signal or based on the priority level of the signal. The network entity may indicate to the UE priority-based rules for how to convey the configured signal.

[0055] Aspects of the present disclosure are first described in the context of wireless communication systems. Aspects of the present disclosure are further illustrated and described with reference to multiplexing patterns, signaling diagrams, communication schemes, process flows, apparatus diagrams, system diagrams, and flow diagrams related to techniques for signaling in SBFD operations.

[0056] Figure 1 An example of a wireless communication system 100 that supports techniques for signaling in SBFD operations 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.

[0057] 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).

[0058] 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 communications with various types of devices, such as Figure 1 Other UEs 115 or network entities 105 are shown.

[0059] 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 a second node.

[0060] In some examples, the network entities 105 may communicate with the core network 130, or communicate 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 link 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 link 162 (e.g., according to the midhaul interface protocol) or the fronthaul communication link 168 (e.g., according to the fronthaul interface protocol) or any combination thereof. The backhaul communication link 120, the midhaul communication link 162, or the fronthaul communication link 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 .

[0061] 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).

[0062] 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)).

[0063] The functional split between 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 functional split of a protocol stack can be employed between CU 160 and DU 165, such that CU 160 can support one or more layers of a protocol stack and DU 165 can support one or more different layers of a protocol stack. In some examples, CU 160 can 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 DU 165 and the RU 170, such that the DU 165 may support one or more layers of the protocol stack, and the RU 170 may support one or more different layers of the protocol stack. The DU 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 a protocol layer (e.g., some functions of a 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., an open fronthaul (FH) interface). In some examples, midhaul communication link 162 or fronthaul communication link 168 may be implemented based on interfaces (eg, channels) between layers of a protocol stack supported by respective network entities 105 that communicate via those communication links.

[0064] In some wireless communication systems (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 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., 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.

[0065] 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 the techniques described herein for signaling in SBFD operations. 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).

[0066] 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.

[0067] 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.

[0068] 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 portion (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 portion of a network entity 105 (e.g., base station 140, CU 160, DU 165, RU 170) of a RAN communicating with another device (e.g., directly or via one or more other network entities 105).

[0069] In some examples, such as in a carrier aggregation configuration, a carrier may also have acquisition signaling or control signaling that coordinates the operation of other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute RF Channel Number (EARFCN)) and may be identified based on a channel raster for discovery by UE 115. A carrier may operate in a standalone mode, in which case initial acquisition and connection may be made by UE 115 via the carrier, or a carrier may operate in a non-standalone mode, in which case the connection is anchored using a different carrier (e.g., a different carrier of the same or different radio access technology).

[0070] 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, among other transmission configurations. A carrier may carry either downlink communications or uplink communications (e.g., in FDD mode), or may be configured to carry both downlink communications and uplink communications (e.g., in TDD mode).

[0071] 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 a "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of a set of bandwidths (e.g., 1.4 megahertz (MHz), 3 MHz, 5 MHz, 10 MHz, 15 MHz, 20 MHz, 40 MHz, or 80 MHz) of a carrier of a particular radio access technology. A device (e.g., a network entity 105, a UE 115, or both) of the wireless communication system 100 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 a 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 a carrier bandwidth.

[0072] 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 using MCM technology, 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 number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both), so that a relatively high number of resource elements (e.g., in the transmission duration) and a relatively high order modulation scheme may correspond to a relatively high 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.

[0073] 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.

[0074] 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. The time intervals of the communication resources may be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0075] Each frame may include a plurality of consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may be divided 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 100, a time slot may be further divided into a plurality of mini-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.

[0076] A subframe, slot, mini-slot, or symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a transmit time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in a burst of a shortened TTI (sTTI)).

[0077] Carrier multiplexing physical channels may be used for communication according to various techniques. Physical control channels and physical data channels may be multiplexed, 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 to signal via a downlink carrier. 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 UE 115 may monitor or search a control region to obtain 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 .

[0078] 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 various coverage areas 110 using the same or different radio access technologies.

[0079] Some UEs 115 may be configured to employ a reduced power consumption mode of operation, such as half-duplex communication (e.g., a mode that supports one-way communication via transmission or reception but does not transmit and receive concurrently). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power saving techniques for UE 115 include entering a power saving deep sleep mode when not engaged in active communications, 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 subband, which may include a set of subcarriers or resource blocks (RBs)) within a carrier, within a guard band of a carrier, or outside a carrier.

[0080] 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 or 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.

[0081] 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 (e.g., scheduled) by the network entity 105. In some examples, one or more UEs 115 of 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, the network entity 105 may facilitate scheduling of resources for D2D communication. In some other examples, D2D communications may be performed between UEs 115 without involving network entity 105 .

[0082] 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 through the user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to the IP service 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.

[0083] 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.

[0084] The wireless communication system 100 may utilize licensed and unlicensed RF spectrum bands. For example, the wireless communication system 100 may use unlicensed 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 using unlicensed RF spectrum bands, devices such as network entity 105 and UE 115 may employ carrier sensing for conflict detection and avoidance. In some examples, operations using unlicensed bands may be based on a carrier aggregation configuration combined with component carriers operating using licensed bands (e.g., LAA). Operations using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among others.

[0085] 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) communications, 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.

[0086] 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 orientation (e.g., relative to the antenna array of the transmitting device or the receiving device or relative to some other orientation).

[0087] UE 115 and network entity 105 may support retransmission of data to increase the likelihood of data being successfully received. Hybrid automatic repeat request (HARQ) feedback is a technique for increasing the likelihood of correctly receiving data via a communication link (e.g., communication link 125, D2D communication link 135). HARQ may include a combination of error detection (e.g., using a cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ may improve throughput at the MAC layer under poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, a device may support same-slot HARQ feedback, in which case the device may provide HARQ feedback in a specific slot for data received via a previous symbol in the slot. In some other examples, the device may provide HARQ feedback in a subsequent slot or according to some other time interval.

[0088] As described herein, UE 115 may adjust the signaling in the time slot configured for SBFD communication based on the scheduling information received indicating the configured signal in the time slot. In the first option, the corresponding subband may be extended to include the configured signal. If there are remaining frequency resources, the remaining opposite direction subbands may still be used for corresponding communication. In the second option, the remaining frequency resources of the opposite direction subbands may be used for communication in the same direction as the configured signal. In the third option, the configured signal may be canceled, or the portion of the configured signal located outside the corresponding subband may be canceled. In the fourth option, the configured signal may be considered an error. For example, if the signal is a downlink signal, UE 115 may skip receiving the configured signal and send feedback (e.g., a HARQ-NACK feedback message). In some examples, the options may be configured based on the type of signal or based on the priority level of the signal. The network entity 105 may indicate to the UE 115 priority-based rules for how to convey the configured signal.

[0089] Figure 2 Examples of multiplexing patterns 200, 201, and 202 that support techniques for signaling in SBFD operations according to one or more aspects of the present disclosure are illustrated. Multiplexing patterns 200, 201, and 202 may be implemented to implement or facilitate aspects of the wireless communication system 100. For example, multiplexing patterns 200, 201, and 202 illustrate IAB nodes 205, MT devices 210, DU 165, and UE 115 (which may be as described in reference Figure 1 In some implementations, the multiplexing patterns 200, 201, and 202 can support one or more signaling-based mechanisms by which a first device (such as an IAB node 205 or another network entity 105) can inform a UE 115 which time and frequency resources can be used for full-duplex communication.

[0090] In some systems, the network entity 105 or one or more TRPs or any combination thereof may communicate with the UE 115 (e.g., send to, receive from, output to send to, obtain from, or any combination thereof) according to a "baseline" non-full-duplex operation. In such systems, flexible TDD may be disabled at both the network entity 105 and the UE 115. Alternatively, the network entity 105 or one or more TRPs or any combination thereof may communicate with the UE 115 (e.g., send to, receive from, output to send to, obtain from, or any combination thereof) according to any one or more of various types of full-duplex. Such types of full-duplex may involve full-duplex operation at the UE 115 or at the network entity 105 (optionally via one or more TRPs), or at both.

[0091] In a first example type of full-duplex, the UE 115 may communicate with a first TRP (such as TRP 1) via a downlink (so that TRP 1 sends signaling to the UE 115) and the UE 115 may communicate with a second TRP (such as TRP 2) via an uplink (so that the UE 115 sends signaling to TRP 2). In such a first example type of full-duplex (which may be associated with an mTRP deployment), flexible TDD may be disabled at the network entity 105 and may be enabled at the UE 115. In a second example type of full-duplex, the network entity 105 may communicate with the first UE 115 via a downlink and may communicate with the second UE 115 via an uplink. In such a second example type of full-duplex (which may be associated with an IAB deployment), flexible TDD may be enabled at the network entity 105 and may be disabled at the first UE and the second UE 115. In a third example type of full-duplex, the network entity 105 may communicate with the UE 115 via both the downlink and the uplink. In such a third example type of full-duplex, flexible TDD may be enabled at both the network entity 105 and the UE 115.

[0092] In addition, one or more network entities 105 or one or more TRPs, or any combination thereof, may communicate with (e.g., transmit to, receive from, output to transmit to, obtain from, or any combination thereof) one or more UEs 115 according to one or more of various deployment scenarios utilizing a type of full-duplex. In a first deployment scenario, a full-duplex network entity 105 (e.g., as described in reference Figure 1 The illustrated and described base station 140) may communicate with multiple half-duplex UEs 115. For example, the first network entity 105 may send downlink signaling to the first UE 115 and may concurrently receive uplink signaling from the second UE 115. The second network entity 105 may send downlink signaling to the third UE 115 and may concurrently receive uplink signaling from the fourth UE 115. In such deployment scenarios, cross-link interference (CLI) may occur between the various communicating devices (where uplink signaling may interfere with downlink signaling), and each of the two full-duplex network entities 105 may experience a certain amount of self-interference.

[0093] In a second deployment scenario, a full-duplex network entity 105 may communicate with a full-duplex UE 115, such as a full-duplex customer premises equipment (CPE). For example, the full-duplex network entity 105 may send downlink signaling to the full-duplex UE 115 and concurrently receive uplink signaling from the full-duplex UE 115. In some aspects, the full-duplex network entity 105 may also send downlink signaling to another UE 115, such as a half-duplex UE 115, and in such aspects, CLI may occur between the two UEs 115. In addition, the full-duplex network entity 105 may experience CLI from the other network entity 105, and both the full-duplex network entity 105 and the full-duplex UE 115 may experience self-interference.

[0094] In a third deployment scenario, a half-duplex network entity 105 or TRP (such as in an mTRP deployment) may communicate with a full-duplex UE 115 (such as a full-duplex CPE). For example, a first network entity 105 or TRP may send downlink signaling to a full-duplex UE 115, and the full-duplex UE 115 may concurrently send uplink signaling to a second network entity 105 or TRP. In some aspects, the first network entity 105 or TRP may also send downlink signaling to another UE 115 (such as a half-duplex UE 115), and in such aspects, CLI may occur between the two UEs 115. In addition, the two network entities 105 or TRPs may experience CLI, and the full-duplex UE 115 may experience self-interference.

[0095] In a fourth deployment scenario, a full-duplex IAB node may communicate with various UEs 115, such as half-duplex UEs 115. For example, an IAB node 205, such as an IAB donor, may control or operate multiple IAB nodes 104, and one or more of the multiple IAB nodes 104 may support full-duplex operation. For example, the IAB node 205 may control or operate a first IAB node 104 capable of sending downlink signaling to a first UE 115 and concurrently receiving uplink signaling from a second UE 115, and may control or operate a second IAB node 104 capable of sending downlink signaling to a third UE 115 and concurrently receiving uplink signaling from a fourth UE 115. In such a deployment, the first IAB node and the second IAB node 104 may experience CLI or self-interference from each other, or both. In some aspects, the IAB node 104 may support conditional duplex capability. Additionally or alternatively, the IAB node 104 may support single frequency full duplex and FDM or space division multiplexing (SDM) with resource block group (RBG) granularity.

[0096] In some aspects, the network entity 105, one or more TRPs, and UE 115 may support various evaluation techniques and performance evaluation metrics associated with different deployment scenarios for full-duplex operation (such as for NR duplex). In addition, the network entity 105, one or more TRPs, and UE 115 may support one or more technologies to support coexistence with other systems in any co-channel or adjacent channel for sub-band non-overlapping full-duplex operation or for dynamic or flexible TDD or for both. For example, the network entity 105, one or more TRPs, and UE 115 may support technologies associated with the evolution of duplex operation of NRTDD across various spectrums (including in unpaired spectrum). In such examples, the network entity 105 (via one or more TRPs) may support full-duplex operation, the UE 115 may support half-duplex operation, and the network entity 105 and UE 115 may be configured or expected to have no restrictions on which frequency ranges are available for use.

[0097] Such techniques may include various full-duplex types or schemes and corresponding metrics for evaluating the performance of such full-duplex types or schemes, inter-network entity 105 and inter-UE 115 CLI mitigation techniques, intra-subband CLI and inter-subband CLI mitigation techniques (such as in a specific implementation of sub-band non-overlapping full-duplex), or a metric-based evaluation process for the impact of full-duplex operation on half-duplex operation (assuming coexistence in co-channel and adjacent channels). Additionally or alternatively, such techniques may include a metric-based evaluation process for the impact of RF constraints that consider adjacent channel coexistence and for the impact of RF constraints that consider self-interference, inter-subband CLI and inter-operator CLI at the network entity 105, and inter-subband CLI and inter-operator CLI at the UE 115. In addition, such techniques may include antenna or RF and algorithm design for interference mitigation, including antenna isolation, transmit interference management suppression in the receive side portion, filtering, and digital interference suppression. In addition, such techniques may comply with one or more regulations or network specifications associated with full-duplex operation in TDD unpaired spectrum.

[0098] In some aspects, various devices within the system may support a signaling mechanism to inform the UE 115 of the time or frequency locations of subbands that the network entity 105 may use for full-duplex operation, such as for SBFD operation. In addition, the various devices may support specific resource allocations in symbols or time slots with subbands that the network entity 105 may use for full-duplex operation, such as for SBFD operation.

[0099] Multiplexing patterns 200, 201, and 202 may support various types of resource management and various types of multiplexing. For example, multiplexing pattern 200-a and multiplexing pattern 200-b may illustrate TDM. Multiplexing pattern 200-a may illustrate DU transmission and reception, and multiplexing pattern 200-b may illustrate MT transmission and reception. In the examples of multiplexing pattern 200-a and multiplexing pattern 200-b, the MT downlink or uplink may use a first set of time domain resources, and the DU downlink or uplink may use a second set of (non-overlapping) time domain resources.

[0100] Multiplexing mode 201-a and multiplexing mode 201-b may illustrate SDM reception and SDM transmission, respectively. For example, multiplexing mode 201-a illustrates MT reception and DU reception (which may be performed using overlapping or non-overlapping time or frequency resources), and multiplexing mode 201-b illustrates MT transmission and DU transmission (which may be performed using overlapping or non-overlapping time or frequency resources). Multiplexing mode 202-a and multiplexing mode 202-b illustrate example full-duplex scenarios. For example, multiplexing mode 202-a illustrates MT transmission and DU reception (which may be performed using overlapping or non-overlapping time or frequency resources), and multiplexing mode 202-b illustrates MT reception and DU transmission (which may be performed using overlapping or non-overlapping time or frequency resources).

[0101] In any SDM or full-duplex scenario, communications may occur concurrently or at different times and may be performed using different frequency resources, using partially overlapping frequency resources, or using the same frequency resources. For example, various devices or components may communicate MT downlinks or uplinks and DU downlinks or uplinks using non-overlapping frequency resources (e.g., in an FDM scheme), using partially overlapping frequency resources, or using completely overlapping frequency resources. In addition, various devices or components may use any combination of MT downlinks or uplinks and DU downlinks or uplinks across different subbands (e.g., across different subbands). In addition, various devices or components may support switching across different configurations over time (e.g., slot by slot).

[0102] Figure 3 An example of a signaling diagram 300 that supports techniques for signaling in SBFD operations according to one or more aspects of the present disclosure is illustrated. The signaling diagram 300 may be implemented or implemented to implement or facilitate aspects of the wireless communication system 100 or any one or more of the multiplexing patterns 200, 201, and 202. For example, the signaling diagram 300 illustrates communications between the UE 115-a and the network entity 105-a, which may be reference Figure 1Examples of corresponding devices described. In some implementations, the UE 115-a and the network entity 105-a may support one or more signaling-based mechanisms by which the network entity 105-a may inform the UE 115-a which time and frequency resources are available for full-duplex communication configured via a per-subband timeslot format.

[0103] In some cases, the UE 115-a and the network entity 105-a may utilize a sub-band specific slot format configuration to indicate which time or frequency resources are scheduled for full-duplex communication, and select between a sub-band specific slot format or a baseline slot format in the same manner. Such a signaling mechanism may promote greater adoption of full-duplex communication and simplify scheduling of full-duplex communication.

[0104] In some cases, full-duplex communication may cause or otherwise induce self-interference at one or both of the UE 115-a and the network entity 105-a. Accordingly, in some implementations, the UE 115-a and the network entity 105-a may further support one or more configuration or signaling-based mechanisms, according to which the UE 115-a and the network entity 105-a may configure a guard band between frequency resources allocated for concurrent uplink and downlink communications according to a sub-band-specific time slot format. In other words, the UE 115-a and the network entity 105-a may support a communication scheme, according to which the UE 115-a and the network entity 105-a may select or indicate a guard band RB during a symbol or time slot associated with full-duplex communication.

[0105] like Figure 3 As illustrated in , the UE 115-a and the network entity 105-a may be configured to communicate in one or more time intervals 325 (e.g., one or more time slots). For example, the time interval 325-a may be configured for communication in a first direction (e.g., downlink communication), and the time interval 325-c may be configured for communication in a second direction (e.g., uplink communication). In some examples, the network entity 105-a may output a first message 310 of a time interval 325-b configured for SBFD communication. For example, the first message 310 may indicate that in the time interval 325-b, one or more subbands 320 (e.g., subband 320-a and subband 320-c) are reserved for communication in the first direction (e.g., downlink communication), and one or more subbands 320 (e.g., subband 320-b) are reserved for communication in the second direction (e.g., uplink communication).

[0106] However, in some cases, the configured signal (e.g., a downlink signal or an uplink signal) may not be restricted to the reserved subband 320. For example, the network entity 105-a may output a second message 315 indicating scheduling information for the configured signal in the time interval 325-b. In some examples, the configured signal may include a synchronization signal block (SSB), a CORESET (e.g., CORESET0), a semi-persistent signaling (SPS) transmission, a configured grant (CG) transmission, a physical uplink control channel (PUCCH), a channel state information reference signal (CSI-RS), a radio link monitoring (RLM) signal, a beam failure detection (BFD) signal, a physical random access channel (PRACH), another reference signal, another control signal, or another data signal.

[0107] As described herein, UE 115-a may adjust signaling in time interval 325-b based on scheduling information in second message 315. In a first option, the corresponding subband 320 may be extended to include a configured signal for a portion of time interval 325-b. If there are remaining frequency resources, the remaining opposite direction subband 320 may still be used for corresponding communication. In a second option, the remaining frequency resources of the opposite direction subband 320 may be used for communication in the same direction as the configured signal. In a third option, the configured signal may be canceled, or a portion of the configured signal located outside the corresponding subband 320 may be canceled. In a fourth option, the configured signal may be considered an error. For example, if the signal is a downlink signal, UE 115-a may skip receiving the configured signal and send feedback (e.g., NACK feedback) in a subsequent time interval 325. In some examples, the options may be configured based on the type of signal or based on the priority level of the signal. The network entity 105-a may indicate to UE 115-a priority-based rules for how to communicate the configured signal.

[0108] Figure 4 An example of a communication scheme 400 that supports techniques for signaling in SBFD operation according to one or more aspects of the present disclosure is illustrated. The communication schemes 400 and 401 may be implemented or implanted to implement aspects of the wireless communication system 100, any one or more of the multiplexing patterns 200, 201, and 202, or the signaling diagram 300. For example, the UE 115 and the network entity 105 may employ the communication schemes 400 and 401 to add a guard band between frequency resources allocated for concurrent uplink and downlink communications conforming to a subband-specific slot format configuration.

[0109] According to communication schemes 400 and 401, UE 115 and network entities may define one or more relatively narrow subbands representing guard bands RBs between each downlink and uplink subband. The slot format associated with such narrow guard bands may include an "NA" value or a bitmap (where a first bit (such as a 0 bit) indicates that the corresponding slot or symbol is available for use, and a second bit (such as a 1 bit) indicates that the corresponding slot or symbol is not available for use).

[0110] For example, and as illustrated in the communication scheme 400, the UE 115 and the network entity 105 may support subband-specific slot format configurations for a plurality of subbands 405, including subband 405-a, subband 405-b, subband 405-c, subband 405-d, and subband 405-e. The network entity 105 may indicate a first slot format configuration "DDDDDD" corresponding to a first index of the subband 405-a, a second slot format configuration "UUUUU" corresponding to a second index of the subband 405-b, and a third slot format configuration "DDDDDD" corresponding to a third index of the subband 405-c. To indicate the guard bands between the subbands 405-a, 405-b, and 405-c, the network entity 105 may indicate a slot format "NA ... NA" or "11111" corresponding to the fourth index of the subband 405-d and another slot format "NA ... NA" or "11111" corresponding to the fifth index of the subband 405-e. Such slot formats "NA ... NA" or "11111" may indicate that the RBs of the subbands 405-d and 405-e are not available for communication and are used as guard bands for full-duplex communication.

[0111] For further example, and as illustrated in the communication scheme 401, the UE 115 and the network entity 105 may support subband-specific slot format configurations for multiple subbands 410 (including subband 410-a, subband 410-b, subband 410-c, subband 410-d, and subband 410-e). The network entity may indicate a first slot format "DDDDDDDDDDUUUUU" corresponding to a first index of subband 410-a, a second slot format "DDDDDUUUUUUUUUU" corresponding to a second index of subband 410-b, and a third slot format "DDDDDDDDDDUUUUUU" corresponding to a third index of subband 410-c. Thus, each of subband 410-a, subband 410-b, and subband 410-c may be allocated for downlink communication during a first time interval 415-a (which may include 5 symbols or slots). During a second time interval 415-b (which may include 5 symbols or time slots), subband 410-a and subband 410-c may be allocated for downlink communications and subband 410-b may be allocated for uplink communications. During a third time interval 415-c (which may include 5 symbols or time slots), each of subband 410-a, subband 410-b, and subband 410-c may be allocated for uplink communications.

[0112] The network entity 105 may also indicate (e.g., via a second message) a time slot format “DDDDDNA ... NAUUUUU” or “000001111100000” corresponding to the fourth index of subband 410-d and another time slot format “DDDDDNA ... NAUUUUU” or “000001111100000” corresponding to the fifth index of subband 410-e. Such time slot formats “NA ... NA” or “11111” may indicate that the RBs of subband 410-d and subband 410-e are not available for communication and are used as guard bands for full-duplex communication. Thus, the UE 115 and the network entity 105 may use subband 410-d and subband 410-e as guard bands during the second time interval 415-b, but may otherwise use subband 410-d and subband 410-e for communication (such as during the first time interval 415-a and the third time interval 415-c).

[0113] Figure 5An example of a communication scheme 500 that supports techniques for signaling in SBFD operations in accordance with one or more aspects of the present disclosure is illustrated. The communication scheme 500 may be implemented or implanted to implement aspects of the wireless communication system 100, any one or more of the multiplexing patterns 200, 201, and 202, or the signaling diagram 300. For example, the UE 115 and the network entity 105 may employ the communication scheme 500 to add a guard band 510 between frequency resources (such as subbands 505) allocated for concurrent uplink and downlink communications conforming to a subband-specific time slot format configuration.

[0114] In some implementations, the network entity 105 may explicitly signal one or more guard bands 510 to be used between subbands 505 associated with different transmission directions. For example, the network entity 105 may indicate a value N, which may be a configurable value, and a certain number of N RBs may be correspondingly unused when applicable (e.g., when adjacent subbands 505 are allocated for uplink and downlink, respectively, during at least partially overlapping time intervals). For example, the CU entity may indicate N to the DU entity, and the DU entity may use the N RBs as guard bands 510 when appropriate.

[0115] Additionally or alternatively, the UE 115 and the network entity 105 may support rules (such as rules provided by a network specification) for indicating that the UE 115 and the network entity 105 are to borrow N RBs between each downlink and uplink subband 505 from either or both of the downlink subband 505 or the uplink subband 505 as a guard band 510 on the associated SBFD symbol or slot. N may be indicated from the network entity 105 (and configurable), may be a fixed value, or may be a function of the size of the subband 505 from which the RBs are reserved, for example.

[0116] For example, and as illustrated in the communication scheme 500, subband 505-a may be configured for downlink communication, subband 505-b may be configured for uplink communication, and subband 505-c may be configured for downlink communication. Thus, in some examples, UE 115 and network entity 105 may reserve RBs from subband 505-b and suppress the use of the reserved RBs for communication. For example, UE 115 and network entity 105 may use a first set of reserved RBs as a guard band 510-a between subband 505-b and subband 505-c and may use a second set of reserved RBs as a guard band 510-b between subband 505-a and subband 505-b. Furthermore, although illustrated and described in the context of reserving RBs from subband 505-b, UE 115 and network entity 105 may additionally or alternatively reserve RBs from one or both of subband 505-a and subband 505-c.

[0117] Figure 6 An example of a communication scheme 600 that supports techniques for signaling in SBFD operations according to one or more aspects of the present disclosure is illustrated. The communication scheme 600 may be implemented or implanted to implement aspects of the wireless communication system 100, any one or more of the multiplexing patterns 200, 201, and 202, or the signaling diagram 300. For example, the UE 115 and the network entity 105 may employ the communication scheme 600 to improve SBFD communications.

[0118] like Figure 6 As illustrated in , the UE 115 and the network entity 105 may be configured to communicate in one or more time intervals 605 (e.g., one or more time slots). For example, the time interval 605-a may be configured for communication in a first direction (e.g., downlink communication), and the time interval 605-c may be configured for communication in a second direction (e.g., uplink communication). In some examples, the network entity 105 may output a first message of a time interval 605-b configured for SBFD communication. For example, the first message may indicate that in the time interval 605-b, one or more subbands 610 (e.g., subband 610-a and subband 610-c) are reserved for communication in the first direction (e.g., downlink communication), and one or more subbands 610 (e.g., subband 610-b) are reserved for communication in the second direction (e.g., uplink communication). In some examples, the first message may also indicate one or more guard bands 615 between the subbands 610. For example, guard band 615 - a may separate sub-band 610 - a and sub-band 610 - b , and guard band 615 - b may separate sub-band 610 - b and sub-band 610 - c .

[0119] However, in some cases, the configured signal 620 (e.g., a downlink signal or an uplink signal) may not be restricted to the reserved subband 610. For example, the network entity 105 may output a second message indicating scheduling information for the configured signal 620 in the time interval 605-b. As described herein, the UE 115 may adjust the signaling in the time interval 605-b based on the scheduling information in the second message.

[0120] In some examples, subband 610 (e.g., subband 610-a) may be extended to include frequency resources for configured signal 620 for a portion of time interval 605-b. Figure 6As illustrated in , subband 610-a may be extended to include frequency resources of subband 610-b and, in some cases, frequency resources of guard band 615-a. Based on extended subband 610-a, the UE may be configured to communicate (e.g., send, receive, obtain, or output for transmission) configured signal 620 in extended subband 610-a.

[0121] In some examples, if there are remaining frequency resources in portion 625 of subband 610-b, portion 625 may still be used for corresponding communication in the configured direction of subband 610-b. In some examples, portion 625 of subband 610-b may be used for communication in the same direction as configured signal 620. In some examples, UE 115 may adjust signaling in RB set 630 in subband 610-c, where RB set 630 may overlap with configured signal 620 in the time domain. For example, UE 115 and network entity 105 may be configured to use RB set 630 for communication in the same direction as configured signal 620, or UE 115 and network entity 105 may be configured to use RB set 630 for corresponding communication in the configured direction of subband 610-c. In some examples, the operation for communicating configured signal 620 may be based on the type of configured signal 620, or based on the priority level of configured signal 620. The network entity 105 may indicate to the UE 115 the priority-based rules for how the configured signal 620 is communicated.

[0122] Figure 7 An example of a communication scheme 700 that supports techniques for signaling in SBFD operations according to one or more aspects of the present disclosure is illustrated. The communication scheme 700 may be implemented or implanted to implement aspects of the wireless communication system 100, any one or more of the multiplexing patterns 200, 201, and 202, or the signaling diagram 300. For example, the UE 115 and the network entity 105 may employ the communication scheme 700 to improve SBFD communications.

[0123] like Figure 7As illustrated in , the UE 115 and the network entity 105 may be configured to communicate in one or more time intervals 705 (e.g., one or more time slots). For example, the time interval 705-a may be configured for communication in a first direction (e.g., downlink communication), and the time interval 705-c may be configured for communication in a second direction (e.g., uplink communication). In some examples, the network entity 105 may output a first message of a time interval 705-b configured for SBFD communication. For example, the first message may indicate that in the time interval 705-b, one or more subbands 710 (e.g., subband 710-a and subband 710-c) are reserved for communication in the first direction (e.g., downlink communication), and one or more subbands 710 (e.g., subband 710-b) are reserved for communication in the second direction (e.g., uplink communication). In some examples, the first message may also indicate one or more guard bands 715 between the subbands 710. For example, guard band 715 - a may separate sub-band 710 - a and sub-band 710 - b , and guard band 715 - b may separate sub-band 710 - b and sub-band 710 - c .

[0124] However, in some cases, the configured signal 720 (e.g., a downlink signal or an uplink signal) may not be restricted to the reserved subband 710. For example, the network entity 105 may output a second message indicating scheduling information for the configured signal 720 in the time interval 705-b. As described herein, the UE 115 may adjust the signaling in the time interval 705-b based on the scheduling information in the second message.

[0125] In some examples, the configured signal 720 may be canceled. That is, the network entity 105 and the UE 115 may be configured to refrain from communicating the configured signal 720. In some examples, the network entity 105 may send scheduling information indicating a subsequent time interval 705 in which the configured signal 720 is to be communicated. In some examples, the network entity 105 and the UE 115 may be configured to communicate a portion 725-a of the configured signal 720 within the reserved subband 710-a and cancel a portion 725-b of the configured signal outside the subband 710-a. In some examples, the operation for communicating the configured signal 720 may be based on the type of the configured signal 720, or based on the priority level of the configured signal 720. The network entity 105 may indicate to the UE 115 a priority-based rule for how to communicate the configured signal 720.

[0126] Figure 8An example of a communication scheme 800 that supports techniques for signaling in SBFD operations according to one or more aspects of the present disclosure is illustrated. The communication scheme 800 may be implemented or implanted to implement aspects of the wireless communication system 100, any one or more of the multiplexing patterns 200, 201, and 202, or the signaling diagram 300. For example, the UE 115 and the network entity 105 may employ the communication scheme 800 to improve SBFD communications.

[0127] like Figure 8 As illustrated in , the UE 115 and the network entity 105 may be configured to communicate in one or more time intervals 805 (e.g., one or more time slots). For example, the time interval 805-a may be configured for communication in a first direction (e.g., downlink communication), and the time interval 805-c may be configured for communication in a second direction (e.g., uplink communication). In some examples, the network entity 105 may output a first message of a time interval 805-b configured for SBFD communication. For example, the first message may indicate that in the time interval 805-b, one or more subbands 810 (e.g., subband 810-a and subband 810-c) are reserved for communication in the first direction (e.g., downlink communication), and one or more subbands 810 (e.g., subband 810-b) are reserved for communication in the second direction (e.g., uplink communication). In some examples, the first message may also indicate one or more guard bands 815 between the subbands 810. For example, guard band 815 - a may separate sub-band 810 - a and sub-band 810 - b , and guard band 815 - b may separate sub-band 810 - b and sub-band 810 - c .

[0128] However, in some cases, the configured signal 820 (e.g., a downlink signal or an uplink signal) may not be restricted to the reserved subband 810. For example, the network entity 105 may output a second message indicating scheduling information for the configured signal 820 in the time interval 805-b. As described herein, the UE 115 may adjust the signaling in the time interval 805-b based on the scheduling information in the second message.

[0129] In some examples, the configured signal 820 may be considered an error. For example, if the configured signal 820 is a downlink signal, the UE 115 may skip monitoring the configured signal 820 and send a feedback message 825 (e.g., NACK feedback) in the time interval 805-d. In some examples, the operation for communicating the configured signal 820 may be based on the type of the configured signal 820, or based on the priority level of the configured signal 820. The network entity 105 may indicate to the UE 115 the priority-based rules for how to communicate the configured signal 820.

[0130] Fig. 9 An example of a process flow 900 for supporting techniques for signaling in SBFD operations in accordance with one or more aspects of the present disclosure is illustrated. The process flow 900 may be implemented or implanted to implement aspects of the wireless communication system 100, any one or more of the multiplexing patterns 200, 201, and 202, or the signaling diagram 300. For example, the process flow 900 may include example operations associated with the UE 115-b or the network entity 105-b, which may be reference Figure 1 Examples of corresponding devices described. In the following description of process flow 900, operations between UE 115-b and network entity 105-b may be performed in an order different from the example order shown, or operations performed by UE 115-b or network entity 105-b may be performed in a different order or at a different time. Some operations may also be omitted from process flow 900, and other operations may be added to process flow 900. The operations performed by UE 115-b and network entity 105-b may support improvements to SBFD operations, and in some examples, may improve communication efficiency and other benefits.

[0131] At 905, the network entity 105-b may output a first message configuring a time interval (e.g., a time slot) for SBFD communication. For example, the first message may indicate that in the time interval, one or more subbands are reserved for communication in a first direction (e.g., uplink communication) and one or more subbands are reserved for communication in a second direction (e.g., downlink communication). In some examples, the first message may also indicate one or more guard bands between the reserved subbands.

[0132] At 910, the network entity 105-b may output a second message indicating scheduling information for a signal in the time interval. That is, the second message may indicate a set of frequency resources used to convey the signal. The signal may be an uplink signal, a downlink signal, or a signal in another direction. As indicated in the scheduling information, the signal may not be restricted to a reserved subband. In some examples, the signal may include an SSB, a CORESET (e.g., CORESET0), an SPS transmission, a CG transmission, a PUCCH, a CSI-RS, an RLM signal, a BFD signal, a PRACH, another reference signal, another control signal, or another data signal.

[0133] In some examples, network entity 105-b may output a third message indicating priority information associated with the signal at 915. In some examples, the third message may be included in a single transmission with the second message.

[0134] At 920, UE 115-b and network entity 105-b may communicate in a set of frequency resources. In some examples, UE 115-b may adjust signaling in the set of frequency resources based on scheduling information in the second message. In a first option, the corresponding subband may be extended to include a signal for a portion of the time interval. If there are remaining frequency resources, the remaining opposite direction subbands may still be used for corresponding communications. In a second option, the remaining frequency resources of the opposite direction subband may be used for communications in the same direction as the signal. In a third option, the signal may be canceled, or a portion of the signal located outside the corresponding subband may be canceled. In a fourth option, the signal may be considered an error.

[0135] In some examples, the options may be configured based on the type of signal or based on the priority level of the signal (e.g., based on priority information included in the third message). In a first example, a signal (e.g., SSB, PRACH, or CORESET0) may be assigned a first priority level (e.g., "high" priority), and the UE 115-b and the network entity 105-b may apply the first option or the second option to the communication. In a second example, a signal (e.g., an SPS transmission, a CG transmission, a reference signal, or a PUCCH carrying a channel state information (CSI) report or a scheduling request (SR)) may be assigned a second priority level (e.g., "medium" priority), and the UE 115-b and the network entity 105-b may apply the first option, the second option, or the third option to the communication. In a third example, a signal (e.g., an SPS transmission that does not include emergency services) may be assigned a third priority level (e.g., "low" priority), and the UE 115-b and the network entity 105-b may apply the third option or the fourth option to the communication.

[0136] In some examples, at 925, UE 115-b may output a feedback message associated with the signal. For example, if the signal is a downlink signal and the UE applies the fourth option, UE 115-b may skip receiving the signal in the communication at 920 and send NACK feedback in the feedback message. By implementing one or more of the described techniques for SBFD communication, UE 115-b and network entity 105-b may be able to send data more efficiently or in a manner that increases data throughput, or consider power consumption or processing load, etc.

[0137] Fig.10A block diagram 1000 of a device 1005 supporting techniques for signaling in SBFD operations according to one or more aspects of the present disclosure is shown. The device 1005 may be an example of aspects of the UE 115 as described herein. The device 1005 may include a receiver 1010, a transmitter 1015, and a communication manager 1020. The device 1005 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

[0138] The receiver 1010 may provide means for receiving information (such as packets, user data, control information, or any combination thereof) associated with various information channels (e.g., control channels, data channels, information channels related to techniques for signaling in SBFD operations). The information may be communicated to other components of the device 1005. The receiver 1010 may utilize a single antenna or a collection of multiple antennas.
