Collision handling for sub-band full duplex aware user equipment

Abstract

Methods, systems, and devices for wireless communication are described. A network entity may implement a sub-band full duplex communication scheme. For half-duplex UEs, each time slot may be configured as either a downlink time slot or an uplink time slot. Half-duplex UEs may be scheduled with transmissions in directions that collide (e.g., opposite) with respect to slot directions configured for the UE. The UE may determine whether to communicate the scheduled transmission in a conflicting direction of the configured slot direction according to a conflict solution. In addition to the transmission scheduled for the opposite direction to the time slot, the UE may receive scheduling information for a second transmission scheduled for the same direction as the time slot. The UE may apply the collision solution to determine which transmission to communicate.

Technical Field

[0002] The following relates to wireless communications related to collision handling for sub-band full-duplex aware user equipment (UE). Background Art

[0003] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, etc. 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 communication of a communication device, which may be referred to as a UE. Summary of the invention

[0004] The described technology relates to improved methods, systems, devices and apparatuses for supporting collision handling for sub-band full-duplex (SBFD) aware user equipment (UE). For example, the described technology provides conflict resolution for transmissions scheduled for the UE in a conflicting direction that is a configured direction of a time interval (e.g., a time slot or symbol) of the UE. In some wireless communication systems, a network entity may implement an SBFD communication scheme. A half-duplex UE may send uplink communications or may receive downlink communications in a given time resource, but the half-duplex UE cannot simultaneously send and receive in the same time resource. Each time slot for a half-duplex UE may be indicated or configured as any one of a downlink time slot, an uplink time slot, or a flexible time slot. An SBFD aware half-duplex UE may be scheduled (e.g., dynamically scheduled via downlink control information (DCI) or via any one of higher layer semi-static scheduling (such as, radio resource control (RRC))) with respect to transmissions in a direction that conflicts (e.g., opposite) with respect to a time slot direction configured or indicated for the half-duplex UE. For example, an SBFD-aware half-duplex UE may be scheduled for uplink transmission in a time slot configured as a downlink time slot of the half-duplex UE (using an uplink subband of the time slot) or a downlink transmission in a time slot configured as an uplink time slot of the half-duplex UE (using a downlink subband of the time slot). The half-duplex UE may determine whether to communicate the scheduled transmission in a conflicting direction of a time interval (e.g., time slot) direction configured for the half-duplex UE (where the time slot is a SBFD time slot of the network entity) based on a conflict resolution method. In some aspects, in addition to a transmission scheduled in a time slot for a direction opposite to the time slot, the half-duplex UE may also receive scheduling information for a second transmission scheduled in a time slot for the same direction as the time slot. The UE may apply a conflict resolution method to determine whether to communicate the transmission in the opposite direction of the time slot or the second transmission in the same direction as the time slot.

[0060] A network entity may implement a sub-band full-duplex (SBFD) communication scheme, in which a first set of frequency resources (which may include one or more non-contiguous sub-bands) may be used for communication in one direction (e.g., one of the uplink or downlink), and a second set of frequency resources (which may include one or more non-contiguous sub-bands) may be used for communication in the same time interval (e.g., the same time slot or symbol) in the other direction. Some half-duplex user equipment (UE) may be aware that the network may operate in SBFD. A half-duplex UE may send uplink communications or may receive downlink communications in a given time resource, but a half-duplex UE cannot simultaneously send and receive in the same time resource. Each time slot for a half-duplex UE may be indicated or configured (e.g., via radio resource control (RRC) signaling) as either a downlink time slot, an uplink time slot, or a flexible time slot. An SBFD-aware half-duplex UE may be scheduled (e.g., either dynamically via downlink control information (DCI) or via higher layer semi-static scheduling (such as, RRC)) with transmissions in a direction that conflicts with (e.g., is opposite to) a time slot direction configured for the half-duplex UE. For example, an SBFD-aware half-duplex UE may be scheduled for uplink transmissions (using an uplink subband of the time slot) in a time slot that is configured as a downlink time slot for the half-duplex UE or for downlink transmissions (using a downlink subband of the time slot) in a time slot that is configured as an uplink time slot for the half-duplex UE. Currently, there is no conflict handling rule that specifies whether an SBFD-aware half-duplex UE may transmit or receive transmissions in a time slot in a direction that conflicts with a time slot direction configured for the half-duplex UE.

[0061] A half-duplex UE may determine whether to communicate a scheduled transmission in a conflicting direction of a time interval (e.g., time slot) direction configured for the half-duplex UE (wherein the time slot is a SBFD time slot of a network entity) based on a conflict resolution method. In some cases, if the UE is scheduled for a scheduled transmission in the opposite direction of the time slot direction configured for the UE, the UE may interpret the time slot as a flexible time slot, and thus the UE may communicate the transmission. For example, the UE may transmit an uplink transmission in an uplink resource of an SBFD time slot indicated to the UE as a downlink time slot of the UE, or the UE may receive a downlink transmission in a downlink resource of an SBFD time slot indicated to the UE as an uplink time slot of the UE. In some cases, the UE may regard a scheduled communication in a direction that conflicts with the time slot direction of the UE as an error condition, and the UE may discard or cancel the transmission accordingly. In some cases, the UE may be configured to communicate a scheduled transmission in the opposite direction of the time slot direction configured for the UE.

[0062] In some aspects, in addition to a transmission scheduled in a time slot for a direction opposite to the time slot, a half-duplex UE may also receive scheduling information for a second transmission scheduled in a time slot for the same direction as the time slot. The UE may apply a conflict resolution method to determine whether to communicate the transmission in the opposite direction of the time slot or the second transmission in the same direction as the time slot. For example, a conflict resolution method may indicate priority to a transmission that is dynamically scheduled, in the same direction as the time slot, in a given direction (e.g., either uplink or downlink may be prioritized), or indicated as having a higher priority level (e.g., based on the type of communication or the number of retransmissions).

[0063] Aspects of the present disclosure are first described in the context of a wireless communication system. Aspects of the present disclosure are further illustrated by and described with reference to resource diagrams and process flows. Aspects of the present disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flow diagrams related to collision handling for SBFD-aware UEs.

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 aspects, 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).

[0065] 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 names. In some aspects, the network entities 105 and the UEs 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 UEs 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 UEs 115 may support signal communications according to one or more radio access technologies (RATs).

[0066] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary or mobile, or stationary and mobile at different times. The UEs 115 may be devices in different forms or with different capabilities. Figure 1 Some example UEs 115 are illustrated in FIG. 1 . The UEs 115 described herein may be capable of supporting communication with various types of devices, such as Figure 1 Communicate with other UEs 115 or network entities 105 as shown.

[0067] As described herein, a node (which may be referred to as a node, a network node, a network entity, or a wireless node) may include, may be, or may be included in (e.g., as a component of) a base station (e.g., any base station described herein), a UE (e.g., any UE described herein), a network controller, an apparatus, a device, a computing system, an integrated access and backhaul (IAB) node, a distributed unit (DU), a central unit (CU), a remote / radio unit (RU) (which may also be referred to as a remote radio unit (RRU)), and / or another processing entity configured to perform any of the techniques described herein. For example, the network node may be a UE. For another example, the network node may be a base station or a network entity. For another example, a first network node may be configured to communicate with a second network node or a third network node. In one aspect of this example, the first network node may be a UE, the second network node may be a base station, and the third network node may be a UE. In another aspect of this example, the first network node may be a UE, the second network node may be a base station, and the third network node may be a base station. In yet other aspects of this example, the first network node, the second network node, and the third network node may be different relative to these examples. Similarly, references to UE, base station, apparatus, device, computing system, etc. may include disclosure of UE, base station, apparatus, device, computing system, etc. as a network node. For example, a disclosure that a UE is configured to receive information from a base station also discloses that a first network node is configured to receive information from a second network node. Consistent with the present disclosure, once a specific example is expanded according to the present disclosure (e.g., a UE is configured to receive information from a base station also discloses that a first network node is configured to receive information from a second network node), a broader example of a narrower example may be interpreted in reverse, but in a broad, open-ended manner. In the above example that a UE is configured to receive information from a base station also discloses that a first network node is configured to receive information from a second network node, the first network node may refer to a first UE configured to receive information, a first base station, a first apparatus, a first device, a first computing system, a first set of one or more components, a first processing entity, etc.; and the second network node may refer to a second UE, a second base station, a second apparatus, a second device, a second computing system, a second set of one or more components, a second processing entity, etc.

[0068] As described herein, different terms may be used in various aspects to describe the communication of information (e.g., any information, signal, etc.). Disclosure of one communication term includes disclosure of other communication terms. For example, a first network node may be described as being configured to send information to a second network node. In this example and consistent with the present disclosure, disclosure that the first network node is configured to send information to the second network node includes disclosure that the first network node is configured to provide, transmit, output, communicate, or send information to the second network node. Similarly, in this example and consistent with the present disclosure, disclosure that the first network node is configured to send information to the second network node includes disclosure that the second network node is configured to receive, obtain, or decode information provided, transmitted, output, communicated, or sent by the first network node.

[0069] In some aspects, the network entities 105 may communicate with the core network 130, or with each other, or both. For example, the network entities 105 may communicate with the core network 130 via one or more backhaul communication links 120 (e.g., according to S1, N2, N3, or other interface protocols). In some aspects, the network entities 105 may communicate with each other via the backhaul communication links 120 (e.g., according to X2, Xn, or other interface protocols), directly (e.g., directly between the network entities 105) or indirectly (e.g., via the core network 130). In some aspects, the network entities 105 may communicate with each other via the midhaul communication links 162 (e.g., according to the midhaul interface protocol) or the fronthaul communication links 168 (e.g., according to the fronthaul interface protocol), or any combination thereof. The backhaul communication links 120, the midhaul communication links 162, or the fronthaul communication links 168 may be or include one or more wired links (e.g., electrical links, optical fiber links), one or more wireless links (e.g., radio links, wireless optical links), etc., or various combinations thereof. UE 115 may communicate with core network 130 via communication link 155 .

[0070] 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 terminology). In some aspects, the network entity 105 (e.g., a base station 140) may be implemented in a converged (e.g., monolithic, stand-alone) base station architecture that may be configured to utilize a protocol stack that is physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as a base station 140).

[0071] In some aspects, 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 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 aspects, 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)).

[0072] The functional split between the CU 160, DU 165, and RU 170 is flexible and may support different functionalities, depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combination thereof) are performed at 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 a protocol stack and the DU 165 may support one or more different layers of the protocol stack. In some aspects, the CU 160 may host higher protocol layer (e.g., Layer 3 (L3), Layer 2 (L2)) functionality and signaling (e.g., 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 the CU 160 and the DU 165 or between the DU 165 and the RU 170 may be within a protocol layer (e.g., some functions of a protocol layer may be performed by one of the CU 160, DU 165, or RU 170, while other functions of the protocol layer are performed by a different one of the CU 160, DU 165, or 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 midhaul 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 fronthaul communication link 168 (e.g., an open fronthaul (FH) interface). In some aspects, midhaul communication link 162 or fronthaul communication link 168 may be implemented according to an interface (eg, a channel) between layers of a protocol stack supported by respective network entities 105 communicating via such communication links.

[0073] 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 (e.g., of the RU 170) of the IAB node 104 for access via the DU 165 of the IAB node 104 (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some aspects, 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.

[0074] For example, an access network (AN) or RAN may include an access node (e.g., an IAB donor), communications between an IAB node 104, and one or more UEs 115. The IAB donor may facilitate connectivity between the core network 130 and the AN (e.g., via a wired or wireless connection to the core network 130). That is, the IAB donor may refer to a RAN node having a wired or wireless connection to the core network 130. The IAB donor may include a CU 160 and at least one DU 165 (e.g., and RU 170), in which case the CU 160 may communicate with the core network 130 via an interface (e.g., a backhaul link). The IAB donor and the IAB node 104 may communicate via an F1 interface according to a protocol defining signaling messages (e.g., an F1 AP protocol). Additionally or alternatively, CU 160 may communicate with the core network via an interface (which may be an example of a portion of a backhaul link) and may communicate with other CUs 160 (e.g., CUs 160 associated with alternative IAB donors) via an Xn-C interface (which may be an example of a portion of a backhaul link).

[0075] The IAB node 104 may refer to a RAN node that provides IAB functionality (e.g., access for UE 115, wireless self-backhaul capability, etc.). The DU 165 may act as a distributed scheduling node toward a child node associated with the IAB node 104, and the IAB-MT may act as a scheduled node toward a parent node associated with the IAB node 104. That is, the IAB donor may be referred to as a parent node that communicates with one or more child nodes (e.g., the IAB donor may relay the transmission of the UE through one or more other IAB nodes 104). Additionally or alternatively, the IAB node 104 may also be referred to as a parent node or child node of other IAB nodes 104, depending on the relay chain or configuration of the AN. Therefore, the IAB-MT entity of the IAB node 104 may provide a Uu interface for the child IAB node 104 to receive signaling from the parent IAB node 104, and the DU interface (e.g., DU 165) may provide a Uu interface for the parent IAB node 104 to signal to the child IAB node 104 or the UE 115.

[0076] For example, the IAB node 104 may be referred to as a parent node supporting communications for a child IAB node or as a child IAB node associated with an IAB donor, or both. The IAB donor may include a CU 160 having a wired or wireless connection (e.g., backhaul communication link 120) to the core network 130, and may act as a parent node of the IAB node 104. For example, the DU 165 of the IAB donor may relay the transmission to the UE 115 through the IAB node 104, or may directly signal the transmission to the UE 115, or both. The CU 160 of the IAB donor may signal the IAB node 104 via the F1 interface that the communication link is established, and the IAB node 104 may schedule the transmission (e.g., the transmission relayed from the IAB donor to the UE 115) through the DU 165. That is, data may be relayed to and from the IAB node 104 via the NR Uu interface of the MT to the IAB node 104 via signaling. Communications with the IAB node 104 may be scheduled by the DU 165 of the IAB donor, and communications with the IAB node 104 may be scheduled by the DU 165 of the IAB node 104 .

[0077] In the case where the techniques described herein are applied to the context of a decomposed RAN architecture, one or more components of the decomposed RAN architecture may be configured to support collision handling for SBFD-aware UEs as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., a base station 140) may additionally or alternatively be performed by one or more components of the decomposed RAN architecture (e.g., an IAB node 104, a DU 165, a CU 160, a RU 170, a RIC 175, a SMO 180).

[0078] 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 aspects, 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, etc., which may be implemented in various objects such as appliances or vehicles, meters, etc.

[0079] 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, relay base stations, etc. Figure 1 as shown in .

[0080] The UE 115 and the network entity 105 may communicate wirelessly 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 set 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 with 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).

[0081] In some aspects, 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 according to 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 a UE 115 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.

[0082] The communication link 125 shown in the wireless communication system 100 may include downlink transmissions (e.g., forward link transmissions) from the network entity 105 to the UE 115, uplink transmissions (e.g., return link transmissions) from the UE 115 to the network entity 105, or both, as well as other transmission configurations. A carrier may carry 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).

[0083] A carrier may be associated with a particular bandwidth of the RF spectrum, and in some aspects, 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 of carriers for a particular radio access technology (e.g., 1.4 megahertz (MHz), 3 MHz, 5 MHz, 10 MHz, 15 MHz, 20 MHz, 40 MHz, or 80 MHz). 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 communications using a particular carrier bandwidth, or may be capable of being configured to support communications using one of the carrier bandwidths in the set of carrier bandwidths. In some aspects, 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 aspects, each served UE 115 may be configured to operate using a portion (e.g., a subband, a BWP) or all of the carrier bandwidth.

[0084] The signal waveform transmitted via the carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, a resource element may refer to a resource of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, in which case the symbol period and the subcarrier spacing may be inversely related. The 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.

[0085] One or more parameter sets for a carrier may be supported, and a parameter set may include a subcarrier spacing ( ) and cyclic prefix. A carrier may be divided into one or more BWPs with the same or different parameter sets. In some aspects, a UE 115 may be configured with multiple BWPs. In some aspects, a single BWP for a carrier may be active at a given time, and communications for a UE 115 may be limited to the one or more active BWPs.

[0086] 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. seconds, of which can indicate the supported subcarrier spacing, and 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).

[0087] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some aspects, 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, the 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.

[0088] A subframe, a time slot, a mini-time slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In some aspects, 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)).

[0089] Physical channels may be multiplexed according to various techniques for communication using a carrier. For example, physical control channels and physical data channels 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 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 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 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 .

[0090] The network entity 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hotspots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity used to communicate with the network entity 105 (e.g., using a carrier), and may be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or other identifier) ​​used to distinguish adjacent cells. In some aspects, a cell may also refer to a coverage area 110 or a portion of a coverage area 110 (e.g., a sector) on which a logical communication entity operates. Depending on various factors such as the capabilities of the network entity 105, such cells may range from smaller areas (e.g., structures, subsets of structures) to larger areas. For example, a cell may be or may include a building, a subset of a building, or an external space between or overlapping coverage areas 110, and the like.

[0091] A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access to UEs 115 that have a service subscription with a network provider that supports the macro cell. A small cell may be associated with a lower power network entity 105 (e.g., a lower power base station 140) (compared to a macro cell), and the small cell may operate using the same or different (e.g., licensed, unlicensed) frequency band as the macro cell. A small cell may provide unrestricted access to UEs 115 that have a service subscription with a network provider, or may provide restricted access to UEs 115 associated with the small cell (e.g., UEs 115 in a closed subscriber group (CSG), UEs 115 associated with users in a home or office). A network entity 105 may support one or more cells, and may also use one or more component carriers to support communications via one or more cells.

[0092] In some aspects, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)) that may provide access to different types of devices.

[0093] In some aspects, 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 aspects, 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.

[0094] The wireless communication system 100 may support synchronous or asynchronous operation. For synchronous operation, the network entities 105 (e.g., base stations 140) may have similar frame timing, and transmissions from different network entities 105 may be approximately aligned in time. For asynchronous operation, the network entities 105 may have different frame timings, and in some aspects, transmissions from different network entities 105 may not be aligned in time. The techniques described herein may be used for either synchronous operation or asynchronous operation.

[0095] 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). The UE 115 may be designed to support ultra-reliable or low-latency or critical functions. Ultra-reliable communications may include private communications or group communications 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.

[0096] In some aspects, 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 aspects, 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 as configured (e.g., scheduled) by the network entity 105. In some aspects, 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 aspects, 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 other UE 115 in the group. In some aspects, network entity 105 may facilitate scheduling of resources for D2D communications. In some other examples, D2D communications may be performed between UEs 115 without involving network entity 105.

[0097] 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 UEs 115 served by network entities 105 (e.g., base stations 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 services 150 of one or more network operators. IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0098] 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 wavelengths range 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 service 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 the lower frequencies and longer wavelengths of the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0099] The wireless communication system 100 may also operate using a super high frequency (SHF) region, which may be in the range of 3 GHz to 30 GHz (also referred to as a centimeter band), or an extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) (also referred to as a millimeter band). In some aspects, the wireless communication system 100 may support millimeter wave (mmW) communications between a UE 115 and a network entity 105 (e.g., a base station 140, a RU 170), and the EHF antennas of the respective devices may be smaller and more closely spaced than UHF antennas. In some aspects, such techniques may facilitate the use of antenna arrays within a device. However, the propagation of EHF transmissions may be affected by even greater attenuation and shorter range than SHF or UHF transmissions. The techniques disclosed herein may be employed across transmissions using one or more different frequency regions, and the use of frequency bands specified across these frequency regions may vary by country or regulatory agency.

[0100] The wireless communication system 100 can utilize licensed and unlicensed RF spectrum bands. For example, the wireless communication system 100 can use unlicensed bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band) to employ License 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 can employ carrier sensing for collision detection and avoidance. In some aspects, operations performed using unlicensed bands can be based on carrier aggregation configuration (e.g., LAA) in combination with component carriers operating using licensed bands. Operations performed using unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among others.

[0101] The network entity 105 (e.g., base station 140, RU 170) or UE 115 may be equipped with multiple antennas that can be used to employ technologies such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of the network entity 105 or UE 115 may be located in one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some aspects, 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 set of antenna ports of multiple rows and columns that the network entity 105 may 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.

[0102] The network entity 105 or UE 115 can use MIMO communication to utilize multipath signal propagation and improve spectrum efficiency by sending or receiving multiple signals via different spatial layers. Such technology can be referred to as spatial multiplexing. The multiple signals can be sent, for example, by a transmitting device via different antennas or different combinations of antennas. Similarly, the multiple signals can be received by a receiving device via different antennas or different combinations of antennas. Each of the multiple signals can be referred to as a separate spatial stream and can carry information associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers can be associated with different antenna ports for channel measurement and reporting. MIMO technology includes: single-user MIMO (SU-MIMO), for which multiple spatial layers are sent to the same receiving device; and multi-user MIMO (MU-MIMO), for which multiple spatial layers are sent to multiple devices.

[0103] 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 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 communicated via antenna elements of an antenna array so that some signals propagating in a particular direction relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals communicated via antenna elements may include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. Adjustments associated with each of these antenna elements may be defined by a set of beamforming weights associated with a particular direction (e.g., relative to the antenna array of the transmitting device or the receiving device or relative to some other direction).

[0104] The network entity 105 or the UE 115 may use beam scanning techniques as part of a beamforming operation. For example, the network entity 105 (e.g., the base station 140, the RU 170) may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with the UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be sent multiple times by the network entity 105 along different directions. For example, the network entity 105 may send signals according to different sets of beamforming weights associated with different transmission directions. Transmissions along different beam directions may be used to identify (e.g., by a transmitting device (such as the network entity 105), or by a receiving device (such as the UE 115)) beam directions for later transmission or reception by the network entity 105.

[0105] Some signals, such as data signals associated with a particular receiving device, may be transmitted by a transmitting device (e.g., a transmitting network entity 105, a transmitting UE 115) along a single beam direction (e.g., a direction associated with a receiving device (such as a receiving network entity 105 or a receiving UE 115)). In some aspects, a beam direction associated with transmission along a single beam direction may be determined based on signals transmitted along one or more beam directions. For example, UE 115 may receive one or more of the signals sent by network entity 105 along different directions and may report to network entity 105 an indication of the signal received by UE 115 with the highest signal quality or other acceptable signal quality.

[0106] In some aspects, transmission by a device (e.g., by a network entity 105 or a UE 115) may be performed using multiple beam directions, and the device may generate a combined beam for transmission (e.g., from the network entity 105 to the UE 115) using a combination of digital precoding or beamforming. The UE 115 may report feedback indicating precoding weights for one or more beam directions, and the feedback may correspond to a configured set of beams across a system bandwidth or one or more subbands. The network entity 105 may transmit a reference signal (e.g., a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS)), which may or may not be precoded. The UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel codebook, a linear combination codebook, a port selection codebook). Although these techniques are described with reference to signals sent along one or more directions by a network entity 105 (e.g., base station 140, RU 170), UE 115 may use similar techniques to send signals multiple times along different directions (e.g., to identify a beam direction for subsequent transmission or reception by UE 115), or to send signals along a single direction (e.g., to send data to a receiving device).

[0107] A receiving device (e.g., UE 115) may perform receiving operations according to multiple receiving configurations (e.g., directional listening) when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from a receiving device (e.g., network entity 105). For example, the receiving device may perform reception according to multiple receiving directions by receiving via different antenna subarrays, processing received signals according to different antenna subarrays, receiving according to different receiving beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or processing received signals according to different receiving beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as "listening" according to different receiving configurations or receiving directions. In some aspects, a receiving device may use a single receiving configuration to receive along a single beam direction (e.g., when receiving a data signal). A single receive configuration may be aligned along a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or other acceptable signal quality based on listening according to multiple beam directions).

[0108] The wireless communication system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, communications at the bearer or PDCP layer may be IP-based. The RLC layer may perform packet segmentation and reassembly to communicate via logical channels. The MAC layer may perform priority handling and multiplexing of logical channels into transport channels. The MAC layer may also implement error detection techniques, error correction techniques, or both to support retransmission to improve link efficiency. In the control plane, the RRC layer may provide the establishment, configuration, and maintenance of an RRC connection that supports a radio bearer for user plane data between the UE 115 and the network entity 105 or the core network 130. The PHY layer may map transport channels to physical channels.

[0109] UE 115 and network entity 105 may support retransmission of data to increase the likelihood that the data is 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 aspects, 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.

[0110] In some aspects, the network entity 105 may implement a SBFD communication scheme, wherein a first set of frequency resources (which may include one or more non-contiguous subbands) may be used for communication in one direction (e.g., one of the uplink or downlink), and a second set of frequency resources (which may include one or more non-contiguous subbands) may be used for communication in the other direction in the same time interval (e.g., the same time slot or symbol). In some aspects, the SBFD operation at the network entity may be transparent to the UE 115 (e.g., the time location and frequency location of the subbands used for SBFD operation may be unknown to the UE 115). In some aspects, SBFD may not be transparent to the UE 115. For example, some half-duplex UEs 115 may know that the network entity 105 may operate in SBFD. In some aspects, only the time location of the subbands used for SBFD operation may be known to the UE 115. In some aspects, both the time location and frequency location of the subbands used for SBFD operation may be known to the UE 115. In some aspects, a SBFD time resource (e.g., a SBFD symbol or time slot) may be a downlink time resource having one or more configured uplink subbands. In some aspects, a SBFD time resource (e.g., a SBFD symbol or time slot) may be a flexible time resource having one or more configured uplink subbands or one or more configured downlink subbands.

[0111] A half-duplex UE 115 may send an uplink communication in a given time resource or may receive a downlink communication in a given time resource, but the half-duplex UE cannot simultaneously send and receive in the same time resource. Each time slot for a half-duplex UE 115 may be indicated or configured (e.g., via RRC signaling) as any one of a downlink time slot, an uplink time slot, or a flexible time slot. An SBFD-aware half-duplex UE 115 may be scheduled (e.g., dynamically scheduled via DCI or via any one of higher-layer semi-static scheduling (such as, RRC)) with respect to a transmission in a direction that conflicts (e.g., opposite) with respect to a time slot direction configured for the half-duplex UE 115. For example, an SBFD-aware half-duplex UE 115 may be scheduled for uplink transmission in a time slot configured as a downlink time slot of the half-duplex UE 115 (using an uplink subband of the time slot) or a downlink transmission in a time slot configured as an uplink time slot of the half-duplex UE 115 (using a downlink subband of the time slot).

[0112] The half-duplex UE 115 may determine whether to communicate a scheduled transmission in a conflicting direction of a time interval (e.g., time slot) direction configured for the half-duplex UE 115 (where the time slot is a SBFD time slot of the network entity 105) based on the conflict resolution. In some cases, if the UE 115 is scheduled for a scheduled transmission in an opposite direction to the time slot direction configured for the UE 115, the UE 115 may interpret the time slot as a flexible time slot, and thus the UE 115 may communicate the transmission. For example, the UE 115 may send an uplink transmission in an uplink resource of a SBFD time slot indicated to the UE 115 as a downlink time slot for the UE 115, or the UE 115 may receive a downlink transmission in a downlink resource of a SBFD time slot indicated to the UE 115 as an uplink time slot for the UE 115. In some cases, the UE 115 may consider a scheduled communication in a direction that conflicts with the time slot direction of the UE 115 as an error condition, and the UE 115 may drop or cancel the transmission accordingly. In some cases, the UE 115 may be configured to communicate scheduled transmissions in the opposite direction of the time slot direction configured for the UE 115. In some aspects, the network entity 105 may apply the same conflict resolution as the UE 115 for transmissions between the UE 115 and the network entity that are scheduled for the opposite direction of the time slot direction configured for the UE 115.

[0113] In some aspects, in addition to the transmission scheduled in the time slot for the direction opposite to the time slot, the half-duplex UE 115 may also receive scheduling information for a second transmission scheduled in the time slot for the same direction as the time slot. The UE 115 may apply a conflict resolution method to determine whether to communicate a transmission in the opposite direction of the time slot direction configured for the UE 115 or to communicate a second transmission in the same direction as the time slot direction configured for the UE 115. For example, the conflict resolution method may indicate that a transmission that is dynamically scheduled, in the same direction as the time slot, in a given direction (e.g., either uplink or downlink may be prioritized), or indicated as having a higher priority level (e.g., based on the type of communication or the number of retransmissions) is given priority. In some aspects, the network entity 105 may apply the same conflict resolution method as the UE 115 to determine whether to communicate a transmission in the opposite direction of the time slot direction configured for the UE 115 or to communicate a second transmission in the same direction as the time slot direction configured for the UE 115.

[0114] Figure 2An example of a wireless communication system 200 that supports collision handling for SBFD-aware UEs according to one or more aspects of the present disclosure is illustrated. The wireless communication system 200 may include a UE 115-a, which may be an example of a UE 115 as described herein. The wireless communication system 200 may include a network entity 105-a, which may be an example of a network entity 105 as described herein.

[0115] UE 115-a may communicate with network entity 105-a using communication link 125-a, which may be an example of an NR or LTE link between UE 115-a and network entity 105-a. Communication link 125-a may include a bidirectional link that enables both uplink and downlink communications. For example, UE 115-a may use communication link 125-a to send uplink transmissions, such as uplink control signals or uplink data signals, to network entity 105-a, and network entity 105-a may use communication link 125-a to send downlink transmissions, such as downlink control signals or downlink data signals, to UE 115-a.

[0116] The network entity 105-a and the UE 115-a may implement SBFD communication. Some half-duplex UEs 115 may know that the network may operate in SBFD, so that the UE 115 may be SBFD-aware. Some UEs 115 may operate in a half-duplex configuration, where the UE 115 may send uplink communications (U) in a given time resource or may receive downlink communications (D) in a given time resource, but may not simultaneously send and receive in the same time resource (e.g., such as in a time slot). Each time slot for a half-duplex UE 115 may be a downlink time slot (D), an uplink time slot (U), or a flexible time slot (F). The network entity 105-a may indicate to the UE 115-a that some time slots (D, U, or F) are used for network entity SBFD operation, and indicate to the UE 115-a the positions of the uplink subbands and downlink subbands in the SBFD symbol. An SBFD-aware half-duplex UE 115 may be scheduled (e.g., either dynamically scheduled via DCI or via higher layer semi-static scheduling) with transmissions in a conflicting direction of a configured direction (e.g., a time slot direction) of a time slot for the UE 115. For example, an SBFD-aware half-duplex UE 115-a may be scheduled for uplink transmissions in a downlink time slot (using an uplink subband of the time slot used by the network entity 105-a for SBFD operations) or downlink transmissions in an uplink time slot (using a downlink subband of the time slot used by the network entity 105-a for SBFD operations). As discussed herein, collision handling rules (e.g., collision resolution) may specify whether an SBFD-aware half-duplex UE 115 may transmit or receive transmissions in a time slot in a direction that conflicts with the time slot direction configured for the UE.

[0117] The UE 115-a may be an SBFD-aware half-duplex UE 115. The UE 115-a may receive control signaling 210 from the network entity 105-a, the control signaling including an indication of BWPs, such as BWP 230-a associated with a first communication direction (e.g., downlink), BWP 230-b also associated with the first communication direction, BWP 230-c associated with a second communication direction (e.g., uplink), and BWP 230-d also associated with the second communication direction. The control signaling may indicate which timeslot is associated with which BWP. For example, timeslot 225-a may be associated with BWP 230-a (e.g., a downlink timeslot), timeslot 225-b may be associated with BWP 230-c and BWP 230-b (e.g., an SBFD timeslot), and timeslot 225-c may be associated with BWP 230-d (e.g., an uplink timeslot). In some aspects, the SBFD time slot 225-b may be a downlink time slot having one or more configured uplink subbands (e.g., uplink BWP 230-c). In some aspects, the SBFD time slot 225-b may be a flexible time slot having one or more configured uplink subbands (e.g., uplink BWP 230-c).

[0118] The SBFD time slot (e.g., time slot 225-b) may include a subband 240. For example, BWP 230-b includes a first subband 240-a and a second subband 240-b, which may be non-contiguous in the frequency domain. Each BWP (e.g., frequency band or subband) in BWP 230 may be associated with a corresponding resource set (such as a resource block (RB)). BWP 230-b including the first subband 240-a may be associated with a first set of RBs, and the second subband 240-b may be associated with a second set of RBs, and they may be non-contiguous in the frequency domain. BWP 230-c and its corresponding RBs may not overlap with the first subband 240-a and the second subband 240-b. In some examples, a guard band may include RBs between RBs associated with BWP 230-b and BWP 230-c.

[0119] The control signaling 210 may indicate that the SBFD mode including the BWP 230 - b and the BWP 230 - c is applied to the set of time resources of the time slot 225 - b .

[0120] The network entity 105-a and the UE 115-a may exchange communications 215 during the time slot 225-b, wherein the network entity 105-a operates in SBFD mode via the BWP 230-b and the BWP 230-c. If the UE 115-a is a half-duplex UE, the UE 115-a may be configured to send uplink signals in the BWP 230-c or receive signals in the BWP 230-b in the time slot 225-b. The network entity 105-a may send signals in the BWP 230-b to one or more UEs 115 and receive uplink signals in the BWP 230-c in the time slot 225-b (e.g., in SBFD mode).

[0121] In some examples, control signaling 210 may be RRC signaling. In some examples, control signaling 210 may include a BWP information element (IE) indicating RBs associated with a downlink BWP (e.g., BWP 230-b) and an uplink BWP (e.g., BWP 230-c). For example, control signaling 210 may include an IE indicating an array for each of BWP 230-a and BWP 230-b, the array indicating the RBs included in the respective BWP 230. Control signaling 210 may indicate a communication direction (e.g., uplink or downlink) for each BWP 230 (e.g., BWP 230-b and BWP 230-c). In some examples, control signaling 210 may indicate for each time slot whether the time slot is configured as an uplink time slot, a downlink time slot, or a flexible time slot for UE 115-a. In the flexible time slot, UE 115-a may determine to send an uplink signal or receive a downlink signal. In some examples, control signaling 210 may only indicate a time location as SBFD (e.g., a time slot / symbol in which network entity 105-a performs SBFD communication). In some examples, control signaling 210 may indicate both a time location and a frequency location (e.g., RBs for uplink and downlink of a SBFD time slot / symbol).

[0122] In a half-duplex configuration, the network entity 105-a may send a downlink signal in a downlink time slot via BWP 230-a and may receive an uplink signal in a time slot BWP 230-d. In half-duplex operation, the time slot may be switched or rotated according to a pattern between an uplink time slot and a downlink time slot. In a half-duplex configuration, the UE 115-a and the network entity 105-a may switch between BWP 230-a and BWP 230-d. For a half-duplex configuration, a BWP pair (e.g., BWP 230-a and BWP 230-d) has the same BWP ID and the same center frequency. For a SBFD configuration, the IE may include an array indicating a plurality of values ​​that may be used to determine an RB in a BWP. The network entity 105-a may configure a BWP 230 and / or a subband 240 to a communication direction as either a downlink or an uplink via control signaling 210.

[0123] In some aspects, UE 115-a may receive scheduling information 245 (e.g., via DCI or RRC signaling) that schedules a transmission 250 that is opposite to the communication direction of UE 115-a for time slot 225-b. For example, control signaling 210 may indicate that time slot 225-b is a downlink time slot for UE 115-a, and scheduling information 245 may schedule an uplink transmission 250 for UE 115-b via BWP 230-c. For another example, control signaling 210 may indicate that time slot 225-b is an uplink time slot for UE 115-a, and scheduling information 245 may schedule a downlink transmission 250 for UE 115-b via BWP 230-c.

[0124] The conflicting communication direction of UE 115-a between the scheduled transmission 250 and the direction indicated by control signaling 210 for time slot 225-b may result in a time domain collision. UE 115-a and network entity 105-a may implement a collision resolution method to resolve such a time domain collision.

[0125] In some examples, control signaling 210 may also indicate a gap period or delay, such as time gap 235-a and time gap 235-b between time resource sets of time slots 225 corresponding to a switch (e.g., uplink transmission and downlink transmission) for BWP 230 to transmit. The gap period (time gap 235-a and time gap 235-b) may include multiple symbols or resources of time slot 225, depending on, for example, a filter tuning delay of UE 115-a.

[0126] Figure 3An example of a resource map 300 that supports collision handling for SBFD-aware UEs according to one or more aspects of the present disclosure is illustrated. The resource map 300 may implement aspects of the wireless communication system 100 or the wireless communication system 200.

[0127] The time slot 325-a may include a BWP 330-a configured for downlink transmission and a BWP 330-b configured for uplink transmission. The time slot 325-b may include a BWP 330-c configured for uplink transmission and a BWP 330-d configured for downlink transmission. The BWP and the subbands associated with the BWP (e.g., the first subband 340-a and the second subband 340-b of the BWP 330-a) may operate and correspond to Figure 2 BWP 230 and sub-band 240.

[0128] Resource diagram 300 illustrates an example of a conflict between a time slot direction semi-statically configured for UE 115 and a semi-statically / RRC-scheduled transmission (e.g., an uplink transmission 305-a in a BWP 330-b of a time slot 325-a, where the time slot 325-a is configured as a downlink time slot for UE 115; or a downlink transmission 305-b in a BWP 330-d of a time slot 325-b, where the time slot 325-b is configured as an uplink time slot for UE 115). For example, an SBFD-aware UE 115 (e.g., aware of the time or time location and frequency location of SBFD operation) may be configured by higher layers (e.g., RRC signaling) to transmit an uplink transmission 305-a, which may be a sounding reference signal (SRS), a physical uplink control channel (PUCCH) transmission, a physical uplink shared channel (PUSCH) transmission, or a physical random access channel (PRACH) transmission. Similarly, the SBFD-aware UE 115 may be configured by higher layers (e.g., RRC signaling) to receive a downlink transmission 305-b, which may be a physical downlink control channel (PDCCH) transmission, a physical downlink shared channel (PDSCH) transmission, or a channel state information reference signal (CSI-RS). The time slot 325-a may be indicated as a downlink time slot by the broadcast parameter dd-UL-DL-ConfigurationCommon, or the time slot 325-b may be indicated as an uplink time slot by the UE-specific RRC parameter tdd-UL-DLConfigurationDedicated. As used herein, semi-static D / U / F may refer to symbols configured as downlink, uplink, or flexible in tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated, respectively.

[0129] As used herein, RRC-D may refer to semi-static PDCCH / PDSCH / CSI-RS transmissions scheduled by higher layer configurations. As used herein, RRC-U may refer to semi-static PUCCH / PUSCH / SRS / PRACH transmissions scheduled by higher layer configurations. Dynamic D may refer to PDSCH / CSI dynamically scheduled by DCI. As used herein, dynamic U may include PUCCH / PUSCH / SRS dynamically scheduled by DCI.

[0130] Control signaling 210 may indicate a slot direction (uplink for slot 325 - a or downlink for slot 325 - b ), and scheduling information 245 (eg, RRC signaling) may schedule uplink transmission 305 - a or downlink transmission 305 - b .

[0131] As part of a conflict resolution process for time domain collisions, the UE 115 and the network entity 105 may determine whether to communicate a scheduled transmission (eg, an uplink transmission 305 - a or a downlink transmission 305 - b ) in an opposite direction to the time slot direction of the UE 115 .

[0132] In some aspects, depending on the conflict resolution, the UE 115 and the network entity 105 may determine to communicate a transmission (eg, an uplink transmission 305 - a or a downlink transmission 305 - b ) in an opposite direction to the time slot direction of the UE 115 .

[0133] In some cases, if the UE 115 is scheduled for a scheduled transmission in the opposite direction of the configured time slot direction, the UE 115 may interpret the time slot (e.g., time slot 325-a or time slot 325-b) as a flexible time slot, and the UE and network entity 105 may communicate the transmission accordingly. For example, the UE 115 may transmit the uplink transmission 305-a in the uplink resources of the time slot 325-a indicated to the UE 115 as a downlink time slot, or the UE 115 may receive the downlink transmission 305-b in the downlink resources of the time slot 325-b indicated to the UE 115 as an uplink time slot.

[0134] In some cases, UE 115 may treat a scheduled transmission (e.g., uplink transmission 305-a or downlink transmission 305-b) as an error condition and discard or cancel the transmission. That is, UE 115 does not send a PUCCH, PUSCH, or PRACH configured by a higher layer, or UE 115 does not receive a PDCCH, PDSCH, or CSI-RS configured by a higher layer on a symbol set.

[0135] Figure 4 An example of a resource map 400 that supports collision handling for SBFD-aware UEs in accordance with one or more aspects of the present disclosure is illustrated. The resource map 400 may implement aspects of the wireless communication system 100 or the wireless communication system 200.

[0136] The time slot 425-a may include a BWP 430-a configured for downlink transmission and a BWP 430-b configured for uplink transmission. The time slot 425-b may include a BWP 430-c configured for uplink transmission and a BWP 430-d configured for downlink transmission. The BWP and the subbands associated with the BWP (e.g., the first subband 440-a and the second subband 440-b of the BWP 430-a) may operate and correspond to Figure 2 BWP 230 and sub-band 240.

[0137] Resource diagram 400 illustrates an example of a conflict between a time slot direction semi-statically configured for UE 115 and a dynamically scheduled transmission (e.g., an uplink transmission 410-a scheduled by DCI 420 in BWP 430-b of time slot 425-a, where time slot 425-a is configured as a downlink time slot for UE 115; or a downlink transmission 410-b scheduled by DCI 420 in BWP 430-d of time slot 425-b, where time slot 425-b is configured as an uplink time slot for UE 115).

[0138] In some examples, when UE 115 detects DCI 420 for a transmission (e.g., uplink transmission 410-a or downlink transmission 410-b) scheduled on a SBFD symbol in a direction opposite to the direction indicated by broadcast parameter tdd-UL-DL-ConfigurationCommon and / or RRC parameter tdd-UL-DL-ConfigurationDedicated (and where control signaling indicates the symbol as a SBFD symbol), UE 115 communicates the dynamically scheduled transmission (e.g., uplink transmission 410-a or downlink transmission 410-b). In some cases, UE 115 communicates the dynamically scheduled transmission (e.g., uplink transmission 410-a or downlink transmission 410-b) as long as it meets the minimum PDCCH processing time (N2) and time slot offset for UE 115.

[0139] Figure 5 An example of a resource map 500 that supports collision handling for SBFD-aware UEs according to one or more aspects of the present disclosure is illustrated. The resource map 500 may implement aspects of the wireless communication system 100 or the wireless communication system 200.

[0140] The time slot 525-a may include a BWP 530-a configured for downlink transmission and a BWP 530-b configured for uplink transmission. The time slot 525-b may include a BWP 530-c configured for uplink transmission and a BWP 530-d configured for downlink transmission. The BWP and the subbands associated with the BWP (e.g., the first subband 540-a and the second subband 540-b of the BWP 530-a) may operate and correspond to Figure 2 The BWP 230 and the sub-band 240 .

[0141] As described herein, in some examples, UE 115 may receive scheduling information that schedules two semi-statically scheduled transmissions in opposite directions (e.g., RRC-D 505-b in BWP 530-a of time slot 525-a and RRC-U 505-a in BWP 530-b of time slot 525-a, or RRC-D 505-d in BWP 530-d of time slot 525-b and RRC-U 505-c in BWP 530-b of time slot 525-a) in a time slot. Time slot 525-a may be configured as a downlink time slot for UE 115, and / or time slot 525-b may be configured as an uplink time slot for UE 115. For example, the SBFD-aware UE 115 may be configured by higher layers to transmit an uplink transmission 505 - a (e.g., SRS, PUCCH, PUSCH, or PRACH) and a downlink transmission 505 - b (e.g., PDCCH, PDSCH, or CSI-RS) in a time slot 525 - a and / or an uplink transmission 505 - c (e.g., SRS, PUCCH, PUSCH, or PRACH) and a downlink transmission 505 - d (e.g., PDCCH, PDSCH, or CSI-RS) in a time slot 525 - b, where the time slot is used for SBFD operations at the network entity.

[0142] In some aspects, based on the conflict resolution, if the time slot 525-a is indicated to the UE 115 as a downlink time slot by the broadcast parameter tdd-UL-DL-ConfigurationCommon or the UE-specific RRC parameter tdd-UL-DLConfigurationDedicated, the UE 115 can determine to receive RRC-D 505-b, and the network entity 105 can be configured to send the RRC-D. In some aspects, based on the conflict resolution, if the time slot 525-b is indicated to the UE 115 as an uplink time slot by the broadcast IE parameter tdd-UL-DL-ConfigurationCommon or the UE-specific RRC parameter tdd-UL-DLConfigurationDedicated, the UE 115 can determine to receive RRC-U 505-c, and the network entity 105 can be configured to send the RRC-U.

[0143] In some aspects, based on conflict resolution, the UE 115 can determine which transmission (e.g., RRC-U 505-a or RRC-D 505-b in time slot 525-a, or RRC-U 505-c or RRC-D 505-d in time slot 525-b) based on priority rules, where the priority rules are based on the configured uplink transmission type or the configured downlink transmission type (e.g., data PDSCH / PUSCH versus PDCCH / PUCCH, content of the transmission, physical / logical priority, time domain behavior, length, or number of repetitions).

[0144] In some aspects, depending on the conflict resolution, the UE 115 and the network entity 105 may always prioritize one communication direction (eg, always prioritize uplink or always prioritize downlink).

[0145] In some aspects, the UE 115 may consider two semi-persistently scheduled transmissions in opposite directions in a time slot as an error case and may drop or cancel both transmissions.

[0146] Figure 6 An example of a resource map 600 that supports collision handling for SBFD-aware UEs according to one or more aspects of the present disclosure is illustrated. The resource map 600 may implement aspects of the wireless communication system 100 or the wireless communication system 200.

[0147] The time slot 625-a may include a BWP 630-a configured for downlink transmission and a BWP 630-b configured for uplink transmission. The time slot 625-b may include a BWP 630-c configured for uplink transmission and a BWP 630-d configured for downlink transmission. The time slot 625-c may include a BWP 630-e configured for downlink transmission and a BWP 630-f configured for uplink transmission. The time slot 625-d may include a BWP 630-g configured for uplink transmission and a BWP 630-h configured for downlink transmission.

[0148] The BWP and the subbands associated with the BWP (eg, the first subband 640-a and the second subband 640-b of the BWP 630-a and the first subband 640-c and the second subband 640-d of the BWP 630-a) may operate and correspond to Figure 2 BWP 230 and sub-band 240.

[0149] Resource diagram 600 illustrates collisions between transmissions semi-statically scheduled by higher layer configuration (eg, RRC-U or RRC-D) and dynamically scheduled transmissions (eg, PUSCH or PDSCH scheduled by DCI 620).

[0150] The SBFD-aware UE 115 may be configured by higher layers to receive RRC-D (e.g., RRC-D 605-a or RRC-D 605-b) and may detect DCI 620 that schedules an uplink transmission (e.g., PUSCH 610-a or PUSCH 610-b) in a SBFD symbol / time slot (e.g., time slot 625-a or time slot 625-b). The time slot 625-a or time slot 625-b may be indicated as downlink or uplink by a broadcast parameter tdd-UL-DL-ConfigurationCommon or a UE-specific RRC parameter tdd-UL-DLConfigurationDedicated. For example, the time slot 625-a may be configured to the UE 115 as a downlink time slot and the time slot 625-b may be configured as an uplink time slot while the time slot is used for SBFD operation at the network entity 105.

[0151] In some examples, based on the conflict resolution, the UE 115 and the network entity 105 may prioritize transmissions scheduled by the DCI 620 (e.g., dynamically scheduled PUSCH 610-a in time slot 625-a and dynamically scheduled PUSCH 610-b in time slot 625-b), and the UE 115 and the network entity 105 may drop or cancel the RRC-D. In some examples, the UE 115 and the network entity 105 may communicate transmissions in the same direction as configured for the time slot (e.g., RRC-D 605-a in time slot 625-a and PUSCH 610-b in time slot 625-b), and may drop or cancel other transmissions (e.g., PUSCH 610-a in time slot 625-a and RRC-D 605-b in time slot 625-b).

[0152] The SBFD-aware UE 115 may be configured by higher layers to receive RRC-U (e.g., RRC-U 605-c or RRC-U 605-d) and may detect DCI 620 that schedules a downlink transmission (e.g., PDSCH 610-c or PDSCH 610-d) in a SBFD symbol / time slot (e.g., time slot 625-c or time slot 625-d). The time slot 625-c or time slot 625-c may be indicated as downlink or uplink by a broadcast parameter tdd-UL-DL-ConfigurationCommon or a UE-specific RRC parameter tdd-UL-DLConfigurationDedicated. For example, the time slot 625-c may be configured to the UE 115 as a downlink time slot and the time slot 625-d may be configured as an uplink time slot while the time slot is used for SBFD operation at the network entity 105.

[0153] In some examples, based on the conflict resolution, the UE 115 and the network entity 105 may prioritize transmissions scheduled by the DCI 620 (e.g., dynamically scheduled PDSCH 610-c in time slot 625-c and dynamically scheduled PDSCH 610-d in time slot 625-d), and the UE 115 and the network entity 105 may drop or cancel the RRC-U. In some examples, the UE 115 and the network entity 105 may communicate transmissions in the same direction as that configured for the time slot (e.g., RRC-U 605-d in time slot 625-d and PDSCH 610-c in time slot 625-c), and may drop or cancel other transmissions (e.g., PDSCH 610-d in time slot 625-d and RRC-U 605-c in time slot 625-c).

[0154] Figure 7An example of a resource map 700 that supports collision handling for SBFD-aware UEs according to one or more aspects of the present disclosure is illustrated. The resource map 700 may implement aspects of the wireless communication system 100 or the wireless communication system 200.

[0155] The time slot 725-a may include a BWP 730-a configured for downlink transmission and a BWP 730-b configured for uplink transmission. The time slot 725-b may include a BWP 730-c configured for uplink transmission and a BWP 730-d configured for downlink transmission. The BWP and the subbands associated with the BWP (e.g., the first subband 740-a and the second subband 740-b of the BWP 730-a) may operate and correspond to Figure 2 The BWP 230 and the sub-band 240 .

[0156] Resource diagram 700 illustrates a collision between two dynamically scheduled transmissions (eg, a PDSCH scheduled by DCI 720 - a and a PUSCH scheduled by DCI 720 - b ).

[0157] The SBFD-aware UE 115 may detect two DCIs (DCI 720-a and DCI 720-b) scheduled for transmission in opposite directions in the same time slot (e.g., time slot 725-a and time slot 725-b). For example, DCI 720-a may schedule PDSCH 710-a and DCI 720-b may schedule PUSCH 710-b in time slot 725-a, and DCI 720-a may schedule PDSCH 710-c and DCI 720-b may schedule PUSCH 710-d in time slot 725-b. Time slot 725-a or time slot 725-b may be indicated as downlink or uplink by the broadcast parameter tdd-UL-DL-ConfigurationCommon or the UE-specific RRC parameter tdd-UL-DLConfigurationDedicated. For example, time slot 725 - a may be configured to UE 115 as a downlink time slot and time slot 725 - b may be configured as an uplink time slot, with UE 115 being aware that the time slots are used for SBFD operations at network entity 105 .

[0158] In some aspects, the UE 115 and the network entity 105 may take such collision and error conditions into account and may cancel or discard the two dynamically scheduled transmissions (e.g., PDSCH 710-a and PUSCH 710-b in time slot 725-a may be discarded or cancelled, or PDSCH 710-c and PUSCH 710-d in time slot 725-b may be discarded or cancelled).

[0159] In some aspects, based on conflict resolution, the UE 115 and the network entity 105 may prioritize transmissions scheduled in the same direction as the time slot direction configured for the UE and may drop or cancel other transmissions. For example, in time slot 725-a, the UE 115 and the network entity 105 may communicate PDSCH 710-a and drop or cancel PUSCH 710-b. Similarly, in time slot 725-b, the UE 115 and the network entity 105 may communicate PUSCH 710-d and drop or cancel PDSCH 710-c.

[0160] In some aspects, according to conflict resolution, the UE 115 and the network entity 105 can prioritize transmissions based on the timing order of the transmission / reception scheduling DCIs (DCI 720-a and DCI 720-b). For example, the UE 115 and the network entity can communicate earlier scheduled transmissions and discard later scheduled transmissions, or vice versa.

[0161] In some aspects, according to the conflict resolution, the UE 115 and the network entity 105 can prioritize transmissions based on the corresponding time domain resource allocation (TDRA) configurations of the PUSCH and PDSCH. The corresponding TDRA can be indicated in the corresponding scheduling DCI (DCI 720-a and DCI 720-b). For example, the UE 115 and the network entity 105 can communicate repeated transmissions, transmissions that started earlier, transmissions that lasted longer, or transmissions based on the k0 / 2 value, and other transmissions can be dropped or cancelled.

[0162] In some aspects, depending on the conflict resolution, the UE 115 and the network entity 105 may prioritize one communication direction (e.g., either uplink or downlink) and may drop or cancel transmissions in the opposite direction. In some aspects, the scheduling DCI may include a bit field for the priority of the scheduled communications.

[0163] Figure 8An example of a process flow 800 for supporting collision handling for SBFD-aware UEs according to one or more aspects of the present disclosure is illustrated. The process flow 800 may include a UE 115-b, which may be an example of a UE 115 as described herein. The process flow 800 may include a network entity 105-b, which may be an example of a network entity 105 as described herein. In the following description of the process flow 800, operations between the network entity 105-b and the UE 115-b may be sent in an order different from the example order shown, or operations performed by the network entity 105-b and the UE 115-b may be performed in a different order or at a different time. Some operations may also be omitted from the process flow 800, and other operations may be added to the process flow 800.

[0164] At 805, the network entity 105-b may send control information, and the UE 115-b may receive the control information, the control information including an indication that a time interval is associated with SBFD communications for the network entity 105-b, wherein the control information also includes an indication of a first set of frequency resources for the time interval associated with a first communication direction and a second set of frequency resources for the time interval associated with a second communication direction, and wherein the control information includes an indication that the time interval is associated with the first communication direction of the UE 115-b.

[0165] At 810, network entity 105-b may send scheduling information for a first transmission between UE 115-b and network entity 105-b in the time interval and the second set of frequency resources used for the time interval, and UE 115-b may receive the scheduling information, wherein the scheduling information includes an indication that the first transmission is associated with the second communication direction.

[0166] At 815, the network entity 105-b and the UE 115-b may communicate via the time interval according to a conflict resolution based on the time interval being associated with the first communication direction of the UE 115-b and the first transmission being associated with the second communication direction.

[0167] In some aspects, communicating via the time interval includes: communicating the first transmission via the time interval and the second set of frequency resources in accordance with the conflict resolution. In some aspects, in accordance with the conflict resolution, based on the first transmission being associated with the second communication direction, the time interval is a flexible time interval type, and communicating the first transmission via the second set of time interval and frequency resources is based on the time interval being the flexible time interval type.

[0168] In some aspects, the network entity 105-b and the UE 115-b may communicate the first transmission via the second set of time intervals and frequency resources based on the DCI including the scheduling information in accordance with the conflict resolution, wherein the UE 115-b receiving the scheduling information includes receiving the DCI including the scheduling information.

[0169] In some aspects, network entity 105-b may send second scheduling information for a second transmission between UE 115-b and network entity 105-b in the time interval and the first set of frequency resources used for the time interval, and UE 115-b may receive the second scheduling information, wherein the second scheduling information includes an indication that the second transmission is associated with the first communication direction, and wherein communicating via the time interval includes conveying one of the first transmission or the second transmission via the time interval based on the conflict resolution.

[0173] In some aspects, communicating one of the first transmission or the second transmission via the time interval includes: communicating the second transmission based on the conflict resolution, based on the first communication direction being associated with a higher priority than the second communication direction, the first transmission being a first semi-statically scheduled transmission, and the second transmission being a second semi-statically scheduled transmission.

[0182] Fig. 9 A block diagram 900 of a device 905 supporting collision handling for SBFD-aware UEs according to one or more aspects of the present disclosure is shown. The device 905 may be an example of aspects of the UE 115 as described herein. The device 905 may include a receiver 910, a transmitter 915, and a communication manager 920. The device 905 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

[0183] The receiver 910 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 collision handling for SBFD-aware UEs). The information may be communicated to other components of the device 905. The receiver 910 may utilize a single antenna or a collection of multiple antennas.

[0184] The transmitter 915 may provide means for transmitting signals generated by other components of the device 905. For example, the transmitter 915 may transmit 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 collision handling for SBFD-aware UEs). In some aspects, the transmitter 915 may be co-located with the receiver 910 in a transceiver module. The transmitter 915 may utilize a single antenna or a collection of multiple antennas.

[0185] The communication manager 920, the receiver 910, the transmitter 915, or various combinations thereof, or various components thereof, may be examples of means for performing various aspects of collision handling for SBFD-aware UEs as described herein. For example, the communication manager 920, the receiver 910, the transmitter 915, or various combinations thereof, or components thereof, may support methods for performing one or more of the functions described herein.

[0186] In some aspects, the communication manager 920, the receiver 910, the transmitter 915, or various combinations thereof or components thereof may be implemented in hardware (e.g., in a communication management circuit). The hardware may include a processor, a digital signal processor (DSP), a central processing unit (CPU), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device, a microcontroller, discrete gate or transistor logic components, discrete hardware components, or any combination thereof that is configured as or otherwise supports components for performing the functions described in the present disclosure.
