The following relates to wireless communications including scheduling during time slots with sub-band full-duplex resources.

Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, etc. These systems are capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power). Examples of such multi-access systems include fourth generation (4G) systems (e.g., Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems) and fifth generation (5G) systems (which may be referred to as New Radio (NR) systems). These systems may employ technologies such as: code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), or discrete Fourier transform 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 communication for communication devices, which may be referred to as user equipment (UE).

Some devices of a wireless communication system may operate according to half-duplex constraints, which means that the device may not be able to transmit and receive at the same time. A wireless communication system may support full-duplex devices, which may support transmission and reception at the same time. For example, a network entity may be configured to transmit to a first user equipment (UE) and receive from a second UE on the same time domain resources. Full-duplex communication may support improved communication throughput and efficiency, but may result in increased interference.

The described technology relates to improved methods, systems, devices, and apparatuses that support scheduling during time slots with sub-band full-duplex resources. A network entity may send, and a user equipment (UE) may receive, control signaling to configure or schedule sub-band full-duplex (SBFD) time slots or symbols. The network entity may send, and the UE may receive, control signaling to schedule a timing, a resource block group, or a precoded resource block group that may overlap with a SBFD time slot or symbol.

A wireless communication system may support half-duplex communication, full-duplex communication, or both. For example, a network entity of the wireless communication system may support full-duplex communication, and therefore, the network entity may communicate via uplink and downlink resources simultaneously. Thus, the network entity may transmit to a first user equipment (UE) using a first resource and receive from a second UE using a second resource, and the first resource and/or the second resource may overlap in the time domain within a frequency band or bandwidth portion. For example, the network entity and the UE may be configured with a sub-band full-duplex (SBFD) time slot (e.g., transmission time interval (TTI)) or symbol with separate frequency resources for uplink and downlink communications to support simultaneous transmission/reception at the network entity. However, the utilization of SBFD resources may cause various types of interference, and such interference may be enhanced when UEs are scheduled to have communication resources that conflict with or overlap with SBFD resources.

Various techniques are described herein for resolving communications scheduled in association with SBFD resources. For example, according to the techniques described herein, a UE may receive first control signaling indicating a time slot that includes SBFD resources, and the UE may receive second control signaling scheduling one or more opportunities for communications of a specified signal (e.g., various types of periodic or semi-persistent signals). The UE may apply rules related to opportunities overlapping with the SBFD time slot to adjust communications within the SBFD time slot. For example, the UE may be configured to completely or partially discard an opportunity or to partially or partially modify the SBFD resources.

According to other techniques, a UE may receive first control signaling including symbols having SBFD resources, and receive second control signaling allocating a resource block group (RBG) overlapping the SBFD symbol. One or more resource blocks of the resource block group may overlap with resources of the SBFD resources that conflict with the communication direction of the resource block group. For example, an RBG may be configured for uplink communication, but a resource block (RB) of the RBG may overlap with downlink resources of the SBFD symbol. Thus, the UE may be configured to apply rules to handle resources when this occurs. For example, the UE may discard or not use the RBs that overlap with the conflicting resources, or the UE may adjust or process the SBFD resources to correspond to the communication direction of the RBG. In some cases, the UE considers the size of the RBG and/or the number of RBs that do not overlap with conflicting resources when determining whether to use or adjust the RBG or switch SBFD resources.

Another technique proposes that the UE apply rules when the UE is configured with a precoded resource block group (PRG) for receiving physical downlink shared channel (PDSCH) transmissions that overlap with SBFD symbols. In such cases, the UE may discard non-colliding RBs, treat the PRG as a partial RBG, adjust the size of the number of non-colliding RBs, and/or concatenate the non-colliding RBs with another PRG. In some cases, the PRG is a wideband PRG that may overlap with SBFD with non-contiguous downlink subbands. In such cases, the UE may not use the SBFD resources and/or may monitor PDSCH transmissions in one or both of the downlink resources, and the technique may depend on the UE's ability to monitor in non-contiguous downlink subbands. In other examples, it is not expected that the UE is configured with a partial PRG that overlaps the downlink sub-band and the uplink sub-band. These and other techniques are described in further detail with reference to the accompanying figures.

Aspects of the disclosure are first described in the context of a wireless communication system. Aspects of the disclosure are further described with respect to a wireless communication system showing SBFD communications, resource diagrams, and process flows. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flow diagrams involving scheduling during time slots with sub-band full-duplex resources.

1 illustrates an example of a wireless communication system 100 that supports scheduling during time slots with sub-band full-duplex resources according to one or more aspects of the present disclosure. 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 LTE-Advanced (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.

The network entities 105 may be distributed throughout a geographic area to form the wireless communication system 100 and may include devices of 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 devices, among other terms. 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), and the UE 115 and the network entity 105 may establish one or more communication links 125 over the coverage area 110. The coverage area 110 may be an example of a geographic area over which the network entity 105 and the UE 115 may support transmitting signals according to one or more radio access technologies (RATs).

UE 115 can be dispersed in the whole coverage area 110 of wireless communication system 100, and each UE 115 can be stationary, or mobile, or both at different times. UE 115 can be equipment of different forms or with different capabilities. Some example UE 115 are shown in FIG. 1. UE 115 described herein can support communication with various types of equipment (such as other UE 115 or network entity 105), as shown in FIG. 1.

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, a device, an apparatus, 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 UE 115, the second node may be network entity 105, and the third node may be network entity 105. In other aspects of this example, the first node, the second node, and the third node may be different relative to these examples. Similarly, references to UE 115, network entity 105, devices, equipment, computing systems, etc. may include disclosures that UE 115, network entity 105, devices, equipment, computing systems, etc. are nodes. For example, disclosures that UE 115 is configured to receive information from network entity 105 also disclose that the first node is configured to receive information from the second node.

In some examples, network entities 105 can communicate with core network 130, or with each other, or both. For example, network entities 105 can communicate with core network 130 via one or more backhaul communication links 120 (e.g., according to S1, N2, N3, or other interface protocols). In some examples, network entities 105 can communicate with each other via backhaul communication links 120 (e.g., according to X2, Xn, or other interface protocols) directly (e.g., directly between network entities 105) or indirectly (e.g., via core network 130). In some examples, network entities 105 can communicate with each other via mid-haul communication link 162 (e.g., according to a mid-haul interface protocol) or front-haul communication link 168 (e.g., according to a front-haul interface protocol) or any combination thereof. Backhaul communication link 120, mid-haul communication link 162, or front-haul communication link 168 can be or include one or more wired links (e.g., electrical links, optical fiber links), one or more wireless links (e.g., wireless links, wireless optical links), and other examples or various combinations thereof. UE 115 can communicate with core network 130 via communication link 155.

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 base transceiver station, a radio base station, a 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-e NB), a home Node B, a home evolved Node B, or other suitable terminology). In some examples, the network entity 105 (e.g., a base station 140) may be implemented in a converged (e.g., monolithic, standalone) 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).

In some examples, the network entity 105 can be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture), which can be configured to utilize a protocol stack that is physically or logically distributed among 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, an intelligent 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 a disaggregated RAN architecture may be co-located, or one or more components of the network entity 105 may be located at distributed locations (e.g., separate physical locations). In some examples, one or more network entities 105 of the disaggregated RAN architecture may be implemented as virtual units (eg, virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

The split of functionality between the CU 160, DU 165, and RU 170 is flexible and may support different functionality depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combination thereof) are executed at the CU 160, DU 165, or RU 170. For example, a functional split of a protocol stack may be employed between the CU 160 and DU 165 such that the CU 160 may support one or more layers of the protocol stack and the DU 165 may support one or more different layers of the protocol stack. In some examples, CU 160 can host upper protocol layer (e.g., Layer 3 (L3), Layer 2 (L2)) functionality and signaling (e.g., Radio Resource Control (RRC), Service Data Adaptation Protocol (SDAP), Packet Data Convergence Protocol (PDCP)). CU 160 can be connected to one or more DU 165 or RU 170, and one or more DU 165 or RU 170 can host lower protocol layer (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 can each be at least partially controlled by 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 the CU 160 and the DU 165 or between the DU 165 and the RU 170 may be within the protocol layer (e.g., some functions of a protocol layer may be performed by one of the CU 160, the DU 165, or the RU 170, while other functions of the protocol layer are performed by a different one of the CU 160, the DU 165, or the RU 170). The CU 160 may be further functionally split into CU control plane (CU-CP) and CU user plane (CU-UP) functions. The CU 160 may be connected to one or more DUs 165 via a mid-range communication link 162 (e.g., F1, F1-c, F1-u), and the DU 165 may be connected to one or more RUs 170 via a front-haul communication link 168 (e.g., an open front-haul (FH) interface). In some examples, the mid-range communication link 162 or the front-haul communication link 168 may be implemented according to an interface (e.g., a channel) between layers of a protocol stack supported by a corresponding network entity 105 communicating via such a communication link.

In a wireless communication system (e.g., wireless communication system 100), infrastructure and spectrum resources for wireless access can support wireless backhaul 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) can be partially controlled by each other. One or more IAB nodes 104 can be referred to as a donor entity or an IAB donor. One or more DUs 165 or one or more RUs 170 can be partially controlled 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). IAB nodes 104 may include IAB mobile terminals (IAB-MTs) that are controlled (e.g., scheduled) by DUs 165 of coupled IAB donors. IAB-MTs may include a separate set of antennas for relaying communications with UEs 115, or may share the same antennas of the IAB node 104 (e.g., the same antennas of the RUs 170) for access via the DUs 165 of the IAB node 104 (e.g., referred to as virtual IAB-MTs (vIAB-MTs)). 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 configuration of a relay or access network (e.g., downstream). In such cases, one or more components of the disaggregated 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.

In the case of the techniques described herein applied in the context of a disaggregated RAN architecture, one or more components of the disaggregated RAN architecture may be configured to support scheduling during time slots with sub-band full-duplex resources 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 disaggregated RAN architecture (e.g., an IAB node 104, a DU 165, a CU 160, a RU 170, a RIC 175, a SMO 180).

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

The UE 115 described herein may be capable of communicating with various types of devices, such as other UEs 115 that may sometimes act as repeaters, as well as network entities 105 and network devices (including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples), as shown in FIG. 1 .

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 defined physical layer structure 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 part (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signals (e.g., synchronization signals, system information), control signaling to coordinate operations on the carrier, user data, or other signals. 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 with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may be used with both frequency division duplex (FDD) component carriers and time division duplex (TDD) component carriers. Communications between the network entity 105 and other devices may refer to communications between a device and any portion (e.g., entity, sub-entity) of the network entity 105. For example, when referring to network entity 105, the terms "sending," "receiving," or "communicating" may refer to any portion of a 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).

In some aspects (e.g., in a carrier aggregation configuration), a carrier may also have control signaling to acquire signals or coordinate operation for 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 the channel grid in order to be discovered by a UE 115. A carrier may operate in a standalone mode, in which case a UE 115 may initially acquire and connect via the carrier, or a carrier may operate in a non-standalone mode, in which case a different carrier (e.g., of the same or different radio access technology) is used to anchor the connection.

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 configurations of transmissions. A carrier may carry either downlink or uplink communications (e.g., in FDD mode) or may be configured to carry both downlink and uplink communications (e.g., in TDD mode).

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 carrier or "system bandwidth" of the 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, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)). Devices of the wireless communication system 100 (e.g., the network entity 105, the UE 115, or both) may have a hardware configuration that supports communication using a particular carrier bandwidth, or may be configurable to support communication using one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a network entity 105 or UE 115 that supports concurrent communication using carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate using a portion (e.g., sub-band, BWP) or all of the carrier bandwidth.

The signal waveform transmitted via a carrier may be composed of 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 systems employing MCM techniques, a resource element may refer to the resources of a symbol period (e.g., the duration of a modulated symbol) and a subcarrier, in which case the symbol period and subcarrier spacing may be inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both), such that a relatively high number of resource elements (e.g., in transmit 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, beams), and the use of multiple spatial resources may increase the data rate or data integrity for communications with UE 115.

One or more numerologies for carriers may be supported, and the numerologies may include subcarrier spacing ( ) and a cyclic prefix. A carrier may be divided into one or more BWPs with the same or different numbering schemes. 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 for a UE 115 may be limited to one or more active BWPs.

It can be expressed in basic time units (which can, for example, refer to The sampling period is 2 seconds (where can indicate the supported subcarrier spacing, and The time interval for the network entity 105 or the UE 115 may be represented as a multiple of a supported discrete Fourier transform (DFT) size). The time intervals of the communication resources may be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

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

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

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

In some examples, the network entities 105 (e.g., base stations 140, RUs 170) may be mobile and, therefore, 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 use the same or different radio access technologies to provide coverage for respective coverage areas 110.

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

In some examples, UE 115 may be configured to support direct communication 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 of a group performing D2D communication may be within a coverage area 110 of a network entity 105 (e.g., a base station 140, a RU 170), and the network entity 105 may support aspects of such D2D communication configured by the network entity 105 (e.g., scheduled by the network entity 105). In some examples, one or more UEs 115 in such a group may be outside of 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, groups of UEs 115 communicating via D2D communication may support a one-to-many (1:M) system, where 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, the D2D communication may be performed between the UEs 115 without involving the network entity 105.

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 that manages access and mobility (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) and at least one user plane entity that routes packets to an external network or interconnects to an external network (e.g., a service gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)). The control plane entities may manage non-access layer (NAS) functions such as mobility, authentication, and bearer management for UEs 115 served by network entities 105 (e.g., base stations 140) associated with the core network 130. User IP packets may be transmitted through user plane entities, which may provide IP address allocation and other functions. The user plane entities may connect to IP services 150 for 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.

The wireless communication system 100 may operate using one or more frequency bands, which may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Typically, 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 approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features (which may be referred to as clusters), but the waves may be sufficient to penetrate structures for macro cells to provide service to UEs 115 located indoors. Communications using UHF waves can be associated with smaller antennas and shorter distances (e.g., less than 100 km) compared to communications using smaller frequencies and longer waves in the high-frequency (HF) or very high-frequency (VHF) portions of the spectrum below 300 MHz.

The wireless communication system 100 can utilize both licensed and unlicensed RF spectrum bands. For example, the wireless communication system 100 can employ licensed 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 the unlicensed RF spectrum band, devices (such as network entities 105 and UEs 115) can employ carrier sensing for conflict detection and avoidance. In some examples, operation using the unlicensed band can be based on a carrier aggregation configuration that combines component carriers operating using a licensed band (e.g., LAA). Operations using the unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.

A network entity 105 (e.g., base station 140, RU 170) or UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of a network entity 105 or UE 115 may be located within one or more antenna arrays or antenna panels (which may support MIMO operations or transmit or receive beamforming). For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly (e.g., an antenna tower). In some examples, antennas or antenna arrays associated with a network entity 105 may be located at different geographic locations. The network entity 105 may include an antenna array having a set of rows and columns of antenna ports that the network entity 105 may use to support beamforming for communications with the UE 115. Likewise, 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 transmitted via the antenna ports.

The network entity 105 or UE 115 may use MIMO communications to exploit multipath signal propagation and improve spectral efficiency by sending or receiving multiple signals via different spatial layers. Such techniques may be referred to as spatial multiplexing. For example, a transmitting device may send multiple signals via different antennas or different combinations of antennas. Similarly, a receiving device may receive multiple signals via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry information associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO technology includes single-user MIMO (SU-MIMO) (where multiple spatial layers are sent to the same receiving device) and multi-user MIMO (MU-MIMO) (where multiple spatial layers are sent to multiple devices).

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., network entity 105, UE 115) to form or steer 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 transmitted via antenna elements of an antenna array such that some signals propagating in a particular orientation relative to the antenna array experience constructive interference and other signals experience destructive interference. Adjustments to signals transmitted via antenna elements may include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to the signal carried via the antenna element associated with the device. The adjustments associated with each of the antenna elements may be defined by a set of beamforming weights associated with a particular orientation (eg, relative to an antenna array of a transmitting device or a receiving device, or relative to some other orientation).

The wireless communication system 100 may support half-duplex and full-duplex communication. For example, the network entity 105 of the wireless communication system 100 may support full-duplex communication, which means that the network entity 105 may communicate in the uplink/downlink at the same time. In some cases, the network entity 105 may transmit to the first UE 115 using a first resource and receive from the second UE 115 using a second resource, and the first resource and the second resource may overlap in the time domain within a frequency band or bandwidth portion. In such cases, the UE 115 may perform half-duplex communication while the network entity 105 performs full-duplex communication. Thus, the network entity 105 and the UE 115 may be configured with SBFD time slots or symbols having separate frequency resources for uplink and downlink communications, such as to support simultaneous transmit/receive at the network entity 105. In some cases, the UE 115 or the network entity 105 may be configured with resources (e.g., timing, RBG, PRG) that overlap with SBFD resources. The devices of the wireless communication system 100 may be configured with techniques for handling scenarios when the configured resources overlap with SBFD resources.

The techniques described herein support the application of rules for handling the scheduling of opportunities/communications in conjunction with SBFD time slots/symbols. The first proposal is for handling periodic or semi-persistent scheduled opportunities (e.g., for communications of a specified signal) regarding SBFD resources. The UE 115 may not expect these opportunities to be scheduled to overlap with SBFD resources, or if such scheduling occurs, the UE 115 may perform various operations (e.g., completely or partially discarding the opportunity, completely or partially modifying the SBFD resources). The second proposal is for handling resource block groups (RBGs) that overlap with SBFD resources having the same transmission direction (e.g., uplink/downlink) as the RBG and overlap with SBFD resources having a different transmission direction than the RBG. RBs that overlap with resources with a different direction may be discarded, or the SBFD resources may be adjusted to correspond to the direction of the RBG. In some cases, the technique depends on the number of RBs that overlap relative to the total number of RBs in the RBG. A third proposal involves processing precoded resource block groups (PRGs) for PDSCH reception, where the PRGs overlap with uplink SBFD resources. In such cases, the resources of the PRGs may be discarded or adjusted, or the SBFD resources may be adjusted.

FIG2 illustrates an example of a wireless communication system 200 that supports scheduling during time slots with sub-band full-duplex resources in accordance with one or more aspects of the present disclosure. The wireless communication system 200 may implement or be implemented by aspects of the wireless communication system 100 of FIG1. For example, the wireless communication system 200 includes a UE 115-a and a network entity 105-a, which may be examples of corresponding devices as described with respect to FIG1.

As described herein, the wireless communication system 200 may support MIMO communication, and more specifically, support half-duplex communication, full-duplex communication, or both half-duplex communication and full-duplex communication. In such cases, the network entity 105-a may communicate with two different UEs 115 simultaneously. For example, the network entity 105-a may use a first communication resource to send downlink communication to the first UE 115, and the network entity 105-a may simultaneously use a second communication resource to receive communication from the second UE 115. The first communication resource and the second communication resource may overlap in the time domain, but may be in different frequency sub-bands. For example, the network entity 105 may use time slot 225 for full-duplex communication, and time slot 225 may be an example of a time slot configured with SBFD resources. More specifically, a time slot may include resources in a bandwidth portion 235, and the time slot may include downlink resources 240 across a first frequency subband and uplink resources across a second frequency subband of the bandwidth portion 235. In some examples, the frequency subbands may span the duration of the time slot 225, as shown in time slots 225-a and 225-b. In other examples, the frequency subbands may span a portion of the time slot 225, and another portion of the time slot may include resources across the bandwidth portion. As shown, time slot 225-a includes downlink resources 240 across the bandwidth portion 235, and time slot 225-a includes uplink resources 245 across the bandwidth portion 235. Thus, time slots 225-c and 225-d include both SBFD symbols and non-SBFD symbols. It should be understood that other SBFD time slot configurations are contemplated within the scope of the present disclosure. For example, a SBFD time slot may include flexible symbols or subbands.

SBFD timeslots may be configured in a time domain duplex carrier or in an intra-band carrier aggregation configuration and may support the simultaneous transmission of downlink and uplink signals on a sub-band basis in the same timeslot. Utilization of such resource configurations may support latency reduction. For example, SBFD resources may support the transmission (e.g., by UE 115) of uplink signals in uplink sub-bands that may normally fall in downlink-only timeslots or flexible timeslots. Additionally or alternatively, SBFD resources may support the reception (e.g., by UE 115) of downlink signals in downlink sub-bands that may normally fall in uplink-only timeslots. Thus, these techniques may support latency savings and uplink coverage improvements. Additionally, SBFD resources may support enhanced system capacity, resource utilization, and spectral efficiency. In addition, SBFD resources can support flexible and dynamic uplink and downlink resource adaptation based on uplink and downlink traffic in a robust manner.

2, the network entity 105-a may send one or more control messages to the UE 115-a. For example, the network entity 105-a may send a first control signaling 210 to the UE 115-a, and the first control signaling may indicate SBFD resources, such as one or more time slots 225 or one or more SBFD symbols in a time slot. The network entity 105-a may also send a second control signaling 215 to schedule resources 230 during or relative to the SBFD resources. For example, the second control signaling may schedule one or more opportunities for sending a specified signal, such as a synchronization signal block (SSB), a control message in a control resource set (e.g., CORESET0), a random access message in a random access channel opportunity (RO), a common search space set message, a tracking reference signal (TRS), or a sounding reference signal (SRS). Because such signals may be used to establish and/or maintain communications between the UE 115-a and the network entity 105-a, it may be desirable to implement techniques for reducing interference with such signals and ensuring that such signals are sent.

Thus, the UE 115-a and the network entity 105-a may apply rules for regulating communications in SBFD time slots, and the rules are related to scheduling opportunities for designated signals that overlap with SBFD time slots. In one example, the network entity 105-a may be configured such that the network entity 105-a does not schedule opportunities (for sending designated signals) that overlap with SBFD time slots. Thus, such opportunities may be scheduled only in non-SBFD time slots (such as uplink time slots, downlink time slots, or flexible time slots). Thus, the rules may specify that the UE 115 is not expected to be configured (or instructed) to receive SSB, CORESET#0, CSS, or TRS in a time slot (e.g., time slot 225) that is configured as a SBFD time slot. Additionally or alternatively, the rule may specify that the UE 115 is not expected to be configured (or indicated) to transmit a RO or SRS in a time slot (eg, time slot 225) indicated as a SBFD time slot.

Alternatively, the scheduled time may overlap with the SBFD time slot (or the SBFD time slot may overlap with the time slot). In the case where the scheduled time (for sending the designated signal) and the SBFD time slot overlap, the UE 115-a and the network entity 105-a may adjust the communication in the time slot by transmitting the designated signal during one or more time slots that overlap with the time slot. In such a case, the SBFD time slot (e.g., time slot 225) may be implicitly converted to a non-SBFD time slot (e.g., a traditional downlink, flexible, or uplink time slot), such as the communication direction corresponding to the scheduled time. For example, UE 115-a may receive a downlink signal and may discard any uplink signal or channel configured or scheduled in an uplink subband (e.g., uplink resource 245) in the time slot. Alternatively, UE 115-a may send an uplink signal and may discard any downlink signal or channel configured or scheduled in a downlink subband (e.g., downlink resource 240) in the time slot. Thus, resources in a SBFD time slot having a communication direction (e.g., scheduled by first control signaling 210) that is different from the scheduled timing (e.g., scheduled by second control signaling 215) may be viewed by UE 115-a and network entity 105-a as having different directions.

In some cases, instead of converting the entire time slot to a conventional time slot, only symbols that conflict with the scheduled timing may be converted to non-SBFD symbols according to a rule. In this way, the UE 115-a and the network entity 105-a may transmit a designated signal at one or more timings, and SBFD symbols that overlap with (and include) conflicting SBFD resources may be configured as non-SBFD symbols, such as uplink, downlink, or flexible symbols. For example, UE 115-a receives a downlink signal (designated signal) at one or more times and discards any uplink signal in the OFDM symbols configured or scheduled in the uplink sub-band in the time slot (network entity 105-a does not perform SBFD operation in these symbols) or in the uplink channel. The non-overlapping remaining symbols can be used by the network entity 105-a for SBFD operation. In another example, UE 115-a sends an uplink signal (designated signal) at one or more times and discards any downlink signal in the OFDM symbols or channels configured or scheduled in the downlink sub-band of the SBFD time slot. The remaining symbols can be used by the network entity 105-a for SBFD operation.

Another rule may specify that when opportunities are scheduled to overlap with SBFD time slots, the network entity 105-a and/or UE 115-a will discard (e.g., not use according to the schedule) these opportunities for communication of the specified signal. In this case, the time slot can be used for SBFD operations scheduled by the first control signaling 210. Alternatively, instead of completely discarding the opportunity, the rule may specify that the network entity 105-a and/or UE 115 will partially discard the overlapping opportunity. That is, when the opportunity has a direction that conflicts with SBFD resources (e.g., SSB overlaps with the uplink subband), the opportunity is partially discarded (e.g., the RB that conflicts with the subband is not used). Thus, the UE 115-a and/or the network entity 105-a may apply one or more of a variety of rules for handling opportunities scheduled to overlap with SBFD time slots for communication of a specified signal.

As described in further detail herein, instead of resource 230 being one or more opportunities for communication of a specified signal, resource 230 may be a resource block group or a precoded resource block for communication of a PDSCH transmission. UE 115-a may apply various rules for handling scenarios when such resources are scheduled to overlap with SBFD symbols.

FIG. 3 illustrates an example of a resource graph 300 that supports scheduling during time slots with sub-band full-duplex resources in accordance with one or more aspects of the present disclosure. The resource graph 300 may be implemented by aspects of the wireless communication system 100 of FIG. 1 and by the wireless communication system 200 of FIG. 2 . For example, the UE 115 and the network entity 105 described herein may implement aspects of the resource graph 300. Aspects of the resource graph 300 may support full-duplex operation of the network entity 105 and the UE 115. For example, even though some UEs 115 may not be capable of full-duplex operation, these UEs 115 may be "aware" of the SBFD operation of the network entity. Such UEs 115 may be referred to as "SBFD-aware UEs." For SBFD-aware UEs, various options are available for resource allocation in the frequency domain when the boundaries between RBGs and SBFD subbands are not aligned. For example, the portion of the downlink RBGs that are within the downlink subband may be used for communication, and the portion of the uplink RBGs that are within the uplink subband may be used. Alternatively, the portion of the downlink RBGs that are within the downlink subband may not be used, and the portion of the uplink RBGs that are within the uplink subband may not be used.

The techniques described herein address portions of RBGs that are “outside” of corresponding subbands, where the outer portions of the RBGs overlap with a guard band or a subband having a communication direction opposite to the communication direction of the RBGs. For example, a device (e.g., UE 115 and network entity 105) may apply rules to regulate communication via the outer portions of the RBGs, and the rules may be applied to communications on portions of the RBGs that overlap with communication resources having a communication direction different from the communication direction of the RBGs. According to one example of the rule, the UE 115 may discard RBGs that fall outside of a downlink or uplink subband (e.g., a subband corresponding to the communication direction of the RBG). Example scenario 305-a includes RBGs that are configured for downlink communication (e.g., via control signaling). Scenario 305-a includes a SBFD time slot with a downlink-uplink-downlink (DUD) pattern and a guard band between the uplink sub-band and the downlink sub-band (e.g., guard band 315), and resource blocks of the RBG outside the downlink sub-band (e.g., part of RBG 310-a and 310-b) can be "discarded", which means that the device can avoid using the outer RBs for communication. In the example scenario 305-b and according to the rule, the RBG is an uplink RBG that overlaps with the uplink sub-band, and parts of the RBG can be discarded (e.g., part of the uplink RBG 310-c and part of the uplink RBG 310-d). Part of the downlink RBG 310-e and part of the downlink RBG 310-f of the scene 305-c and part of the uplink RBG 310-g and part of the uplink RBG 310-h of the scene 305-d may similarly be discarded according to the rules.

According to an alternative example of the rule, the device may use the external RB for communication according to the communication direction of the configured RBG. In this way, the conflicting symbols may be treated as (or converted to) traditional symbols, such as downlink symbols (when the RBG has a downlink communication direction), uplink symbols (when the communication direction has an uplink communication direction), or flexible symbols. Therefore, in scenario 305-a, UE 115-a and network entity 105-a may use portions of RBGs 310-a and 310-b that overlap with a guard band, an uplink sub-band, or both for uplink communication. Therefore, uplink sub-band resources may be converted to downlink resources.

However, in some cases, the device may not be able to switch the communication direction. Therefore, the outer partial RBG can be used only when the outer subband is flexible. Therefore, in scenario 305-c, the partial downlink RBG 310-e and the partial downlink RBG 310-f overlap with the flexible subband (of the SBFD symbol), and therefore, the partial downlink RBG 310-e and the partial downlink RBG 310-f can be used for downlink communication (e.g., some or all of the flexible subband is used for downlink). Similarly, in scenario 305-d, the partial uplink RBG 310-g overlaps with the flexible subband, and the partial uplink RBG 310-h overlaps with the flexible subband. Therefore, according to this rule, part of the uplink RBG 310-g and part of the uplink RBG 310-h can be used for uplink communication. In this case, the flexible subband can be used as an uplink resource.

In some cases, the device may apply rules to determine whether a portion of an RBG that is within a subband of an SBFD symbol is used for communication. More specifically, the rules applied by the device may indicate whether the device is to use a portion of an RBG that overlaps with SBFD resources having the same communication direction as the RBG. For example, when the number of RBs within a subband (e.g., overlapping with a downlink subband) is greater than a threshold resource block number (e.g., greater than 50% of the size of the RBG), the portion of the downlink RBG that overlaps with the downlink subband may be used. Similarly, when the number of RBs within an uplink subband is greater than the threshold RB number, the portion of the uplink RBG that is within the uplink subband may be used. In the case where the threshold is 50% and RBG size = 16 RBs, if the number of RBs within the subband is less than 8 RBs, these RBs are not used for communication. In another example, if the number of RBs is greater than 8 RBs, these RBs can be used for communication according to the RBG communication direction.

In some examples, the device may apply a rule that specifies that if a portion of an RBG that is inside a subband (e.g., a portion of an RBG that overlaps a subband having the same communication direction as the RBG) cannot be used, then the entire RBG is not used for communication. Thus, in the above example, if the number of RBs inside a subband is less than a threshold, then the entire RBG is not used for communication. Thus, the rule may specify that when a portion of a downlink RBG that overlaps a downlink subband of an SBFD symbol is not used, then another portion of the RBG that overlaps a protection or uplink subband is not used for communication. Similarly, the rule may specify that when a portion of an uplink RBG that overlaps an uplink subband of an SBFD symbol is not used, then another portion of the RBG that overlaps a protection or downlink subband is not used for communication.

In some examples, based on the application of rules, the entire RBG may be used for communication. In this case, the device may apply one or more rules to determine SBFD operation in an SBFD symbol. For example, when a portion of an uplink RBG inside an uplink subband is used, another portion of the RBG outside the uplink subband may be used only when the SBFD symbol is configured with an uplink in a flexible symbol (e.g., another guard band subband is considered flexible and used for uplink transmission). Similarly, when a portion of a downlink RBG within a downlink sub-band is used, then when an SBFD symbol is configured with a downlink in a flexible symbol, another portion of the RBG outside the downlink sub-band may be used (e.g., another guard band sub-band is considered flexible and used for downlink reception). When a portion of a downlink RBG within a downlink sub-band is used, then when an SBFD symbol is configured with a downlink in a downlink symbol, another portion of the RBG outside the downlink sub-band may be used (e.g., the guard band sub-band is converted back to a downlink symbol and used for downlink reception).

FIG4 illustrates an example of a resource graph 400 that supports scheduling during time slots with sub-band full-duplex resources according to one or more aspects of the present disclosure. The resource graph 400 may be implemented by aspects of the wireless communication system 100 of FIG1 and by the wireless communication system 200 of FIG2. For example, the UE 115 and the network entity 105 described herein may implement aspects of the resource graph 400. Aspects of the resource graph 400 may support full-duplex operation of the network entity 105 and the UE 115.

As described herein, UE 115 may be referred to as "SBFD-aware." An SBFD-aware UE may be configured with a PRG for receiving PDSCH transmissions. For example, the PRG may be configured with a size of two or four RBs. As shown in FIG. 4 , the PRG may be configured such that a PDSCH (e.g., PDSCH 410) may overlap with a SBFD timeslot. The device may be configured to use a wideband precoder for SBFD DMRS channel estimation (e.g., when the DMRS is contiguous). Resource diagram 405 - a includes a contiguous PRG (e.g., single subband scheduling) with wideband demodulation reference signal (DMRS) precoding.

Because a partial PRG or a wideband PRG may overlap with a SBFD symbol, the device may apply rules to adjust the communication in the PRG. For example, for a PRG size of two or four and a remaining RB inside a downlink subband (e.g., a downlink RB that overlaps with a downlink subband), the device may perform various operations according to the rules. For example, it may not be expected that a device (e.g., a UE) is configured with a partial PRG in the middle of a BWP (e.g., an edge of a DL/UL subband). That is, the rule may specify that it is not expected that a UE is configured with a precoded resource block group that overlaps with an uplink subband and a downlink subband of a portion of the bandwidth. In another example, the device may discard the inner RBs if there is no communication of PDSCH (e.g., the UE does not monitor or receive PDSCH in the PRG and the network entity 105 does not send PDSCH in the PRG). Alternatively, the device may treat the PRG as a partial PRG with one RB and may transmit PDSCH in one RB in the inner PRG. Alternatively, the device may concatenate the RBs with one or more neighboring PRGs and form a new PRG of size three (if the neighboring PRG has size two) or size five (if the neighboring PRG has size four).

In the case where the size of the PRG is four and the number of downlink RBs overlapping the downlink subband is two or three, the device may perform one or more different operations according to the rule. For example, it may not be expected that the device (e.g., UE) is configured with a partial PRG in the middle of the BWP (e.g., the edge of the DL/UL subband). That is, the rule may specify that the UE is not expected to be configured with a precoded resource block group that overlaps the uplink subband and the downlink subband of the bandwidth portion. In another example, the device may discard two or three RBs without communication, or treat the RPG as a portion with two RBs or three RBs. In some cases, when there are three RBs within the downlink subband, the device can adjust the size of the PRG to two RBs and discard (eg, not use) the third RB. Alternatively, the device can concatenate the three RBs with one or more adjacent PRGs and form a new PRG of size six or seven.

As shown in resource diagram 405-b, if a wideband PRG is configured and the SBFD timeslot or symbol has non-contiguous downlink subbands, the device can apply rules to adjust the communication in the PRG. In some example applications of the rules, the device can determine not to utilize the SBFD configuration of the timeslot or symbol. Alternatively, the utilization of the SBFD resources can depend on the UE capabilities. For example, if the UE is capable, it can use RBs in the downlink subband for reception while using the same precoder on both downlink subbands. Alternatively, the device can use one of the downlink subbands for communication. For example, the device can select one of the downlink subbands for communication via the RBs and rate match the RBs in another downlink subband. In another example of this rule, the UE is not expected to be configured with non-contiguous RBs across two downlink subbands for PDSCH configured with wideband PRG. That is, it is not expected that the UE is configured with non-contiguous resource blocks across two downlink subbands for receiving a physical downlink shared channel transmission configured with a wideband precoding resource block group.

FIG. 5 illustrates an example of a process flow 500 for supporting scheduling during a time slot with sub-band full-duplex resources in accordance with one or more aspects of the present disclosure. The process flow 500 may implement aspects of the wireless communication system 100, or may be implemented by aspects of the wireless communication system 100. For example, the process flow 500 includes a UE 115-b and a network entity 105-b, which may be examples of corresponding devices as described with respect to FIGS. 1 to 4. In the following description of the process flow 500, operations between the UE 115-b and the network entity 105-b may be sent in a different order than the example order shown, or the operations performed may be performed in a different order or at a different time. Some operations may also be omitted from the process flow 500, and other operations may be added to the process flow 500.

In a first example of process flow 500, at 505, the network entity 105-b may send and the UE 115-b may receive first control signaling indicating a time slot allocated for sub-band full-duplex communication. The time slot may be scheduled to include sub-band full-duplex symbols, each sub-band full-duplex symbol including a combination of uplink resources and downlink resources in a corresponding frequency sub-band.

At 510, the network entity 105-b may send, and the UE 115-b may receive, second control signaling that schedules one or more opportunities for communication of a specified signal within a time slot or outside of a time slot.

At 515, based on rules regarding scheduling timing for designated signals overlapping with the sub-band full-duplex time slot, UE 115-b may adjust and network entity 105-a may participate in communications during the time slot.

In one example of adjusting communications according to a rule, the second control signaling schedules one or more opportunities outside of a time slot according to the rule. In this case, the rule may specify that UE 115 is not expected to transmit a specified signal in a time slot allocated for sub-band full-duplex communications. Therefore, communications during the time slot do not include the specified signal scheduled by the second control signaling.

In other examples of adjusting communications according to rules, the second control signaling schedules one or more timings to overlap with a time slot. In this case, the UE 115-a and the network entity 105-a can transmit a specified signal during one or more timings overlapping with a time slot in a first communication direction and according to the rules, such that the time slot is considered a downlink time slot, an uplink time slot, or a flexible time slot based on the first communication direction. Alternatively, the UE 115-a and the network entity 105-a can transmit a specified signal during one or more timings overlapping with a time slot in a first communication direction and according to the rules, such that one or more symbols that conflict with the one or more timings are converted to a downlink time slot, an uplink time slot, or a flexible symbol based on the first communication direction.

In other examples of adjusting communications, the UE may avoid transmitting the designated signal during one or more time periods based on a rule that specifies that the UE will discard opportunities for communication of the designated signal that overlap with sub-band full-duplex time slots. Instead of discarding one or more opportunities, the UE may discard a portion of one or more opportunities that overlap with resources of a time slot for a different communication direction than the one or more opportunities. In this way, the UE 115-b and the network entity may determine that at least a first portion of the one or more opportunities overlap with a second portion of uplink resources or downlink resources for a communication direction different from the communication direction of the one or more opportunities, and avoid transmitting the designated signal during the first portion based on the rule. The designated signal may be a synchronization signal block, a control message in a control resource set, a random access message in a random access channel timing, a common search space set message, a tracking reference signal, or a sounding reference signal.

In a second example of process flow 500, at 505, the network entity 105-b may send and the UE 115-b may receive first control signaling indicating a sub-band full-duplex symbol that includes at least a first communication resource associated with a first communication direction and spanning a first frequency sub-band and a second communication resource associated with a second communication direction and spanning a second frequency sub-band.

At 510, the network entity 105-b may send, and the UE 115-b may receive, second control signaling that allocates a resource block group for communicating during a sub-band full-duplex symbol. The resource block group may include a plurality of resource blocks and may be associated with a first communication direction, and a first portion of the plurality of resource blocks overlaps a first frequency sub-band of a first communication resource, and a second portion of the plurality of resource blocks overlaps a guard band or a second frequency sub-band of a second communication resource.

At 515, based on rules relating to communication on a portion of a resource block group overlapping communication resources having a communication direction different from a first communication direction of the resource block group, UE 115-b may adjust communication via a second portion of the plurality of resource blocks, and network entity 105-a may participate in communication via a second portion of the plurality of resource blocks.

In some examples, UE 115-b and network entity 105-b can avoid using a second portion of the plurality of resource blocks based on a rule specifying that the UE will discard reception during a resource block that overlaps with a communication resource having a communication direction different from a first communication direction of the resource block group. In some examples, adjusting the communication includes using the second portion for communication via the first communication direction or as a flexible resource based on the rule. If the device determines to use the second portion, the device can modify the second communication resource to have the first communication direction or to have a flexible allocation (e.g., modifying the resource to have a traditional uplink, a downlink, or a flexible symbol). In some examples, UE 115-b and network entity 105-b may determine whether to use a first portion of multiple resource blocks for communication based at least in part on the amount of the first portion relative to a threshold, and the threshold may be based on a total number of resource blocks in the resource block group.

In a third example of process flow 500, at 505, the network entity 105-a may send and the UE 115-b may receive first control signaling indicating a sub-band full-duplex symbol that includes at least a first uplink communication resource across a first frequency sub-band and a second downlink communication resource across a second frequency sub-band.

At 510, the network entity 105-a may send, and the UE 115-a may receive, second control signaling that allocates a precoded resource block set for receiving a physical downlink shared channel transmission. The precoded resource block set may include a plurality of resource blocks, and a first portion of the plurality of resource blocks overlaps with a first frequency subband of a first uplink communication resource.

At 515, based on rules related to communication on the portion of the precoded resource block group that overlaps with uplink communication resources of the sub-band full-duplex symbol, UE 115-b can adjust communication via the precoded resource block group and network entity 105-a can participate in communication via the precoded resource block group.

For example, the UE may not expect to be configured with a partial PRG in the middle of the BWP (e.g., the edge of a downlink/uplink subband). Thus, the second control signaling may schedule the PRG so that the PRG does not overlap with the uplink subband. As another example, if the size of the precoded resource block group is two or four and the number of resource blocks in the first portion is one, the UE 115-b may avoid monitoring physical downlink shared channel transmissions during the first portion based at least in part on the size and the number, and the network entity may send physical downlink shared channel transmissions during the first portion based at least in part on the size and the number. In other examples, UE 115-b may monitor the physical downlink shared channel transmission during the first portion based at least in part on the size and amount, and network entity 105-b may send the physical downlink shared channel transmission during the first portion based at least in part on the size and amount. In other examples, UE 115-b and the network entity may combine the first portion with the second precoded resource block group to generate a combined precoded resource block group based at least in part on the size and amount, and transmit the physical downlink shared channel transmission in the combined precoded resource block group.

If the size of the precoded resource block group is four and the number of resource blocks in the first part is two or three, the device can avoid using the resource block group or use the resource block group for communication of the physical downlink shared channel transmission according to the rule. In other cases, the device can use a sub-portion of the first part for communication of the physical downlink shared channel transmission. That is, the device can effectively adjust the size of the portion overlapping with the sub-band.

In the case where the first control signaling indicates a sub-band full-duplex symbol including non-contiguous downlink sub-bands (for example, the first control signaling indicates a first uplink communication resource, a second downlink communication resource, and a third downlink communication resource that is discontinuous with the second downlink communication resource), and the second control signaling indicates a precoding resource block group as a broadband precoding resource block group, the device may use the precoding resource block group and avoid using uplink resources of the sub-band full-duplex symbol. In other cases, the device may use two downlink sub-bands for communication transmitted by a physical downlink shared channel. In such a case, the first downlink communication resource and the second downlink communication resource may use the same precoder according to a rule. The use of two downlink subbands may depend on the UE's ability to monitor non-contiguous physical downlink shared channel transmissions with wideband precoded resource block groups. In other cases, the device may select one of the downlink subbands for transmitting the physical downlink shared channel transmission. In this case, the unselected resource blocks are rate matched with the selected resources. As another example, the UE is not expected to be configured with non-contiguous RBs spanning two downlink subbands for a PDSCH configured with a wideband PRG. In this way, the wideband PRG is not scheduled to overlap with two downlink subbands.
