Enhanced preemption for multiple consecutive slot transmissions

Abstract

Methods, systems, and devices for wireless communication are described. For example, a first UE may receive an indication of a set of resources available for preemption. The indication of the set of resources may include an indication of a set of consecutive resources. The first UE may select a first set of contiguous resources for transmitting a first message, and may determine that a second UE has reserved a first resource of the set of resources that overlaps the first set of contiguous resources. The first UE may report an indication that the first resource is being preempted based on the overlap. The first UE may perform the reporting based on a first priority of a second message for the first resource, the first priority relative to a second priority of the first message. The first UE may transmit the first message on a second set of contiguous resources based on the report.

Description

Technical Field

[0001] The following relates to wireless communication, including enhanced preemption for multi-slot transmission. Background Technology

[0002] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, message sending and receiving, broadcasting, and so on. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth-generation (4G) systems (such as Long Term Evolution (LTE) systems, LTE-A Advanced (LTE-A) systems, or LTE-A Pro systems) and fifth-generation (5G) systems (which may be referred to as New Radio (NR) systems). These systems can employ technologies such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal FDMA (OFDMA), or Discrete Fourier Transform Extended Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations, each supporting wireless communication of communication devices, which may be referred to as User Equipment (UE).

[0003] Some communication systems support sidelink communication, where each UE can transmit directly to each other. In some cases, a UE can select resources from a resource pool for sidelink transmission with other UEs. For example, a first user equipment (UE) and a second UE can use resources from the resource pool to perform communication. In some aspects, the second UE may attempt to reserve resources in the resource pool that have already been reserved by the first UE. If the first UE and the second UE each transmit on reserved resources, their corresponding transmissions may interfere. This interference may reduce the likelihood of the receiving device receiving the corresponding transmission, and therefore may increase the likelihood of the first UE and the second UE retransmitting their corresponding transmissions. Increased retransmission likelihood may reduce the efficiency of wireless communication. Summary of the Invention

[0004] This disclosure relates to methods, systems, devices, and apparatuses supporting enhanced preemption for multi-continuous time-slot transmission. For example, the described techniques enable user equipment (UE) to resolve resource preemption issues when resources reserved by a first UE for multi-continuous time-slot transmission (MCSt) overlap with resources reserved by other UEs. For example, the first UE may receive an indication of a set of resources available for preemption at a first layer of the first UE and from a second layer of the first UE. In some such examples, the indication of the resource set may include an indication of one or more sets of continuous resources. The first UE may select a first set of continuous resources for transmitting a message and may determine that the second UE has reserved a first resource in the resource set that at least partially overlaps with the first set of continuous resources (e.g., in time and frequency). For example, the first UE may receive sidelink control information (SCI) indicating that the first resource has been reserved by the second UE. Based on receiving the indication that the second UE has reserved the first resource in the resource set, the first UE may report from the first layer to the second layer that the first resource is being preempted. Additionally, the first UE may execute the report based on a first priority of a second message for which the second UE has reserved the first resource, the first priority being relative to a second priority of the first message on the first group of consecutive resources. Based on the report, the first UE may send the first message on a second group of consecutive resources different from the first group of consecutive resources.

[0038] Some communication systems support sidelink communication, where user equipment (UEs) can transmit directly to each other. In some cases, a UE can select resources from a resource pool for sidelink transmission with other UEs. For example, a first UE and a second UE can use resources from the resource pool to perform communication. In some cases, the second UE can attempt to reserve resources in the resource pool that have already been reserved by the first UE. If the reserved resource becomes available for preemption, the first UE can determine whether the resource can be preempted; and if so, it can report the resource to be preempted to a higher layer (e.g., from the first UE's physical (PHY) layer to the first UE's media access control (MAC) layer).

[0039] In some aspects, a first UE may reserve a set of consecutive resources in a resource pool for multi-continuous time-slot transmission (MCSt) (e.g., on time-continuous resources). If a second UE reserves resources in the resource pool that are included in the reserved set of consecutive resources, the first UE may preempt those resources. However, if the preempted resource is not the last resource in a set of consecutive resources (e.g., it is one of the resources preceding the first or last resource), preempting the resource may cause the first UE to lose channel occupancy for the time spanned by the preempted resource. Therefore, the first UE may be unable to transmit on additional resources following the preempted resource. Additionally, the second UE may be unable to contend for the channel of the preempted resource. In any one or both of these scenarios, the efficiency of wireless communication may be reduced.

[0040] This disclosure describes techniques for performing preemption when a first UE or a second UE has reserved a set of consecutive resources for transmitting MCSt. For example, the first UE may receive an indication of a set of resources available for preemption at a first layer (e.g., the PHY layer) and from a second layer (e.g., a higher layer, such as the MAC layer). In some such examples, the indication of the resource set may include an indication of one or more sets of consecutive resources (e.g., an indication of one set of consecutive resources, rather than a separate indication of each resource in the set). The first UE may select a first set of consecutive resources for transmitting a message, wherein the first set of consecutive resources overlaps with a first resource in the set of resources available for preemption. The first UE may determine that the second UE has reserved the first resource in the resource set and may, based on this determination, report from the first layer to the second layer an indication that the first resource is being preempted. In some aspects, the report may be based on a first priority of a second message that the second UE will send on the first resource, the first priority being relative to a second priority of the message sent by the first UE on the first group of consecutive resources. In some aspects, the first UE may report an indication of the first group of consecutive resources (e.g., an indication of the first group of consecutive resources, rather than a separate indication of each resource in the first group of consecutive resources). Following this report, the first UE may send the message on a second group of consecutive resources different from the first group of consecutive resources based on the report.

[0041] The aspects of this disclosure are first described in the context of a wireless communication system. Additional aspects of this disclosure are described in the context of preemption resource indication schemes, resource selection schemes, and process flows. The aspects of this disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts relating to enhanced preemption for multi-continuous time-slot transmission.

[0042] Figure 1 Examples of an enhanced preemptive wireless communication system 100 supporting multi-slot transmission according to one or more aspects of this disclosure are illustrated. The wireless communication system 100 may include one or more network entities 105, one or more UEs 115, and a core network 130. In some 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 expressly mentioned herein.

[0043] Network entity 105 may be distributed across a geographical area to form wireless communication system 100, and may include devices employing different forms or having different capabilities. In various examples, network entity 105 may be referred to as a network element, mobility element, radio access network (RAN) node, or network equipment, among other designations. In some aspects, network entity 105 and UE 115 may wirelessly communicate via one or more communication links 125 (e.g., radio frequency (RF) access links). For example, network entity 105 may support coverage area 110 (e.g., a geographical coverage area) within which UE 115 and network entity 105 may establish one or more communication links 125. Coverage area 110 may be an example of a geographical area within which network entity 105 and UE 115 may support signal communication according to one or more radio access technologies (RATs).

[0044] UE 115 can be distributed throughout the coverage area 110 of wireless communication system 100, and each UE 115 can be stationary or mobile, or stationary and mobile at different times. UE 115 can be devices in different forms or with different capabilities. Figure 1 Some example UE 115s are illustrated herein. The UE 115 described herein may be able to support various types of devices, such as... Figure 1 The other UE 115 or network entity 105 shown communicates.

[0045] As described herein, nodes of the wireless communication system 100 (which may be referred to as network nodes or wireless nodes) may be network entity 105 (e.g., any network entity described herein), UE 115 (e.g., any UE described herein), network controller, apparatus, device, computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, a node may be UE 115. Alternatively, a node may be network entity 105. Furthermore, a first node may be configured to communicate with a second or third node. In one aspect of this example, the first node may be UE 115, the second node may be network entity 105, and the third node may be UE 115. In another aspect of this example, the first node may be UE 115, the second node may be network entity 105, and the third node may be network entity 105. In other aspects of this example, the first node, the second node, and the third node may be different from these examples. Similarly, references to UE 115, network entity 105, device, equipment, computing system, etc., may include disclosures of UE 115, network entity 105, device, equipment, computing system, etc., as nodes. For example, a disclosure that UE 115 is configured to receive information from network entity 105 also discloses that a first node is configured to receive information from a second node.

[0046] In some aspects, network entity 105 may communicate with core network 130, communicate with each other, or both. For example, network entity 105 may communicate with core network 130 via one or more backhaul communication links 120 (e.g., according to S1, N2, N3, or other interface protocols). In some aspects, network entities 105 may communicate with each other directly (e.g., directly between network entities 105) or indirectly (e.g., via core network 130) via backhaul communication links 120 (e.g., according to X2, Xn, or other interface protocols). In some aspects, network entities 105 may communicate with each other via midhaul communication link 162 (e.g., according to midhaul interface protocol) or fronthaul communication link 168 (e.g., according to fronthaul interface protocol) or any combination thereof. Backhaul communication link 120, midhaul communication link 162, or fronthaul communication link 168 may be or include one or more wired links (e.g., electrical links, fiber optic links), one or more wireless links (e.g., radio links, wireless optical links), etc., or various combinations thereof. UE 115 can communicate with core network 130 via communication link 155.

[0047] One or more network entities in network entity 105 described herein may include or be referred to as base station 140 (e.g., transceiver base station, radio base station, NR base station, access point, radio transceiver, node B, eNodeB (eNB), next-generation node B or gigabit node B (any of which may be referred to as gNB), 5G NB, next-generation eNB (ng-eNB), home node B, home evolution node B, or other suitable terms). In some aspects, network entity 105 (e.g., base station 140) may be implemented in an aggregated (e.g., monolithic, self-contained) base station architecture that may be configured to utilize a protocol stack physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as base station 140).

[0048] In some aspects, network entity 105 may be implemented in a decomposed architecture (e.g., a decomposed base station architecture, a decomposed RAN architecture) that can be configured to utilize a protocol stack physically or logically distributed between two or more network entities 105 (such as an integrated access backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN))). For example, network entity 105 may include one or more of the following: a central unit (CU) 160, a distributed unit (DU) 165, a radio unit (e.g., a 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. RU 170 may also be referred to as a radio headend, an intelligent radio headend, a remote radio headend (RRH), a remote radio unit (RRU), or a transmit-receive point (TRP). One or more components of network entity 105 in a decomposed RAN architecture may be co-located, or one or more components of network entity 105 may be located in distributed locations (e.g., separate physical locations). In some aspects, one or more network entities 105 in a decomposed RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0049] The functional splitting among CU 160, DU 165, and RU 170 is flexible and can support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combination thereof) are performed at CU 160, DU 165, or RU 170. For example, a protocol stack functional splitting can be used between CU 160 and DU 165, allowing CU 160 to support one or more layers of the protocol stack, and DU 165 to support one or more different layers of the protocol stack. In some respects, CU 160 can host higher protocol layer (e.g., Layer 3 (L3), Layer 2 (L2)) functionalities and signaling (e.g., Radio Resource Control (RRC), Serving Data Adaptation Protocol (SDAP), Packet Data Convergence Protocol (PDCP)). CU 160 can connect to one or more DU 165 or RU 170, and one or more DU 165 or RU 170 can host lower protocol layers, such as Layer 1 (L1) (e.g., Physical (PHY) layer) or L2 (e.g., Radio Link Control (RLC) layer, Medium Access Control (MAC) layer) functionality and signaling, and each can be at least partially controlled by CU 160. Additionally or alternatively, a protocol stack functional split can be employed between DU 165 and RU 170, such that DU 165 can support one or more layers of the protocol stack, and RU 170 can support one or more different layers of the protocol stack. DU 165 can support one or more different cells (e.g., via one or more RU 170). In some cases, functional decomposition between CU 160 and DU 165, or between DU 165 and RU 170, can be performed within the protocol layer (e.g., some functions of the protocol layer can be performed by one of CU 160, DU 165, or RU 170, while other functions of the protocol layer can be performed by different of CU 160, DU 165, or RU 170). CU 160 can be further functionally decomposed into CU control plane (CU-CP) and CU user plane (CU-UP) functions. CU 160 can be connected to one or more DU 165s via midhaul communication link 162 (e.g., F1, F1-c, F1-u), and DU 165 can be connected to one or more RU 170s via fronthaul communication link 168 (e.g., open fronthaul (FH) interface). In some respects, the midhaul communication link 162 or the fronthaul communication link 168 may be implemented based on the interfaces (e.g., channels) between the layers of the protocol stack, each layer of which is supported by the corresponding network entity 105 communicating via such communication links.

[0050] In some wireless communication systems (e.g., wireless communication system 100), the infrastructure and spectrum resources for radio access can support wireless backhaul link capabilities to supplement wired backhaul connections, thereby providing an IAB network architecture (e.g., to core network 130). In some cases, in an IAB network, one or more network entities 105 (e.g., IAB node 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as donor entities or IAB donors. One or more DU 165s or one or more RU 170s may be partially controlled by one or more CU 160s associated with donor network entity 105 (e.g., donor base station 140). One or more donor network entities 105 (e.g., IAB donors) may communicate with one or more additional network entities 105 (e.g., IAB node 104) via supported access and backhaul links (e.g., backhaul communication link 120). IAB node 104 may include an IAB mobile terminal (IAB-MT) controlled (e.g., scheduled) by a DU 165 of a coupled IAB donor. The IAB-MT may include a separate set of antennas for relaying communication with UE 115, or may share the same antennas (e.g., those of RU 170) for access to IAB node 104 via DU 165 of IAB node 104. (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some aspects, IAB node 104 may include a DU 165 that supports communication links with additional entities (e.g., IAB node 104, UE 115) within a relay chain or configuration (e.g., downstream) of the access network. In such cases, one or more components of the decomposed RAN architecture (e.g., one or more IAB nodes 104 or components of IAB node 104) may be configured to operate according to the techniques described herein.

[0051] For example, the access network (AN) or RAN may include communication between an access node (e.g., an IAB donor), 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, an 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 IAB node 104 may communicate via an F1 interface according to a protocol defining the signaling messages (e.g., the F1 AP protocol). Additionally or alternatively, the CU 160 may communicate with the core network via an interface (which may be a part of the backhaul link) and may communicate with other CU 160s (e.g., CU 160 associated with an alternative IAB donor) via an Xn-C interface (which may be a part of the backhaul link).

[0052] IAB node 104 may refer to a RAN node that provides IAB functionality (e.g., access for UE 115, radio self-backhaul capability, etc.). DU 165 may act as a distributed scheduling node toward child nodes associated with IAB node 104, and IAB-MT may act as a scheduled node toward a parent node associated with IAB node 104. That is, an IAB donor may be referred to as a parent node communicating with one or more child nodes (e.g., an IAB donor may relay UE transmissions through one or more other IAB nodes 104). Additionally or alternatively, depending on the AN's relay chain or configuration, IAB node 104 may also be referred to as a parent node or child node of other IAB nodes 104. Therefore, the IAB-MT entity of IAB node 104 may provide a Uu interface for child IAB node 104 to receive signaling from parent IAB node 104, and the DU interface (e.g., DU 165) may provide a Uu interface for parent IAB node 104 to signal to child IAB node 104 or UE 115.

[0053] For example, IAB node 104 may be referred to as a parent node supporting communication to child IAB nodes, or as a child IAB node associated with an IAB donor, or both. An IAB donor may include a CU 160 having a wired or wireless connection to core network 130 (e.g., backhaul communication link 120) and may act as a parent node of IAB node 104. For example, the IAB donor's DU 165 may relay transmissions to UE 115 via IAB node 104, or may signal transmissions directly to UE 115, or both. The IAB donor's CU 160 may signal the establishment of a communication link to IAB node 104 via an F1 interface, and IAB node 104 may schedule transmissions via DU 165 (e.g., transmissions relayed from the IAB donor to UE 115). That is, data may be relayed to and from IAB node 104 via signaling through the NR Uu interface of the MT to IAB node 104. Communication with IAB node 104 can be scheduled by DU 165 of the IAB donor, and communication with IAB node 104 can be scheduled by DU 165 of IAB node 104.

[0054] In the context of applying the techniques described herein to a decomposed RAN architecture, one or more components of the decomposed RAN architecture can be configured to support enhanced preemption for multi-slot transmission as described herein. For example, some operations described as being performed by UE 115 or network entity 105 (e.g., base station 140) may additionally or alternatively be performed by one or more components of the decomposed RAN architecture (e.g., IAB node 104, DU 165, CU 160, RU 170, RIC 175, SMO 180).

[0055] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or any other suitable term, wherein "device" may also be referred to as a unit, station, terminal, or client, etc. UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some aspects, UE 115 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine-type communication (MTC) device, which can be implemented in various objects such as electrical appliances or vehicles, instruments, etc.

[0056] The UE 115 described herein may be able to communicate with various types of devices, such as other UEs 115 that may sometimes act as relays, as well as network entities 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc. Figure 1 As shown.

[0057] UE 115 and network entity 105 can wirelessly communicate with each other via one or more communication links 125 (e.g., access links) using resources associated with one or more carriers. The term "carrier" can refer to a set of RF spectrum resources having a physical layer structure defined for supporting communication link 125. For example, a carrier for communication link 125 may include a portion of the RF spectrum band (e.g., a bandwidth portion (BWP)) operating according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating carrier operation, user data, or other signaling. Wireless communication system 100 may support communication with UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used for both frequency division duplex (FDD) and time division duplex (TDD) component carriers. Communication between network entity 105 and other devices can refer to communication between these devices and any part of network entity 105 (e.g., entity, sub-entity). For example, the terms “send,” “receive,” or “communicate” when referring to network entity 105 can refer to any part of the RAN’s network entity 105 (e.g., base station 140, CU 160, DU 165, RU170) communicating with another device (e.g., directly or via one or more other network entities 105).

[0058] In some aspects, such as in carrier aggregation configurations, carriers may also have acquisition signaling or control signaling to coordinate the operation of other carriers. Carriers may be associated with frequency channels (e.g., Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute RF Channel Number (EARFCN)) and may be identified according to a channel grating used for discovery by UE 115. Carriers may operate in standalone mode, in which initial acquisition and connection can be performed by UE 115 via that carrier, or in non-standalone mode, in which connection is anchored using different carriers (e.g., different carriers of the same or different radio access technologies).

[0059] The communication link 125 shown in the wireless communication system 100 may include other transmission configurations such as downlink transmission (e.g., forward link transmission) from network entity 105 to UE 115, uplink transmission (e.g., return link transmission) from UE 115 to network entity 105, or both. The carrier may carry downlink communication or uplink communication (e.g., in FDD mode), or may be configured to carry both downlink and uplink communication (e.g., in TDD mode).

[0060] A carrier may be associated with a specific bandwidth of the RF spectrum, and in some aspects, the carrier bandwidth may be referred to as the carrier or the “system bandwidth” of the wireless communication system 100. For example, the carrier bandwidth may be one bandwidth in a set of bandwidths for a particular radio access technology (e.g., 1.4 MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz, 20 MHz, 40 MHz, or 80 MHz). Devices of the wireless communication system 100 (e.g., network entity 105, UE 115, or both) may have hardware configurations that support communication using a specific carrier bandwidth, or may be configured to support communication using one carrier bandwidth in a set of carrier bandwidths. In some aspects, the wireless communication system 100 may include network entity 105 or UE 115 that supports concurrent communication using carriers associated with multiple carrier bandwidths. In some aspects, each served UE 115 may be configured to operate using a portion (e.g., a sub-band, BWP) or all of the carrier bandwidth.

[0061] The signal waveform transmitted via a carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform extended OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element may refer to a resource of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, in which case the symbol period and subcarrier spacing may be inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the decoding rate of the modulation scheme, or both), such that a relatively high number of resource elements (e.g., in the transmission duration) and a relatively high modulation scheme order correspond to a relatively high communication rate. Wireless communication resources may refer to a combination of RF spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial resources may increase the data rate or data integrity used for communication with UE 115.

[0062] It can support one or more sets of parameters for a carrier, and the parameter sets may include subcarrier spacing ( The carrier can be divided into one or more BWPs with the same or different sets of parameters. In some respects, the UE 115 can be configured with multiple BWPs. In some respects, a single BWP for a carrier can be active at a given time, and communication for the UE 115 can be limited to one or more active BWPs.

[0063] The time interval for network entity 105 or UE 115 can be expressed as a multiple of a basic time unit, such as the sampling period. seconds, of which It can represent the supported subcarrier spacing, and This can represent the supported Discrete Fourier Transform (DFT) size. The time interval of the communication resources can be organized according to radio frames, each with a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0064] 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 (e.g., in the time domain) be divided into subframes, and each subframe may be further divided into a number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a number of symbol periods (e.g., depending on the length of the cyclic prefix appended to each symbol period). In some wireless communication systems 100, time slots may be further divided into multiple micro-time slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., The duration of a symbol period is associated with a (number) sampling period. The duration of a symbol period can depend on the subcarrier spacing or the operating frequency band.

[0065] A subframe, time slot, micro-time slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some aspects, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs)).

[0066] Depending on the technology, carriers can be used to multiplex physical channels for communication. One or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques can be used, for example, to multiplex physical control channels and physical data channels for signaling via a downlink carrier. The control region of the physical control channel (e.g., a control resource set (CORESET)) can be defined by a set of symbol periods and can extend across the system bandwidth of the carrier or a subset of that bandwidth. One or more control regions (e.g., CORESET) can be configured for a set of UEs 115. For example, one or more UEs in UE 115 can monitor or search control regions to obtain control information based on one or more search space sets, and each search space set can include one or more control channel candidates in one or more aggregation levels arranged in a concatenated manner. The aggregation level of control channel candidates can refer to the amount of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space set may include: a common search space set configured to transmit control information to multiple UEs 115, and a UE-specific search space set used to transmit control information to a specific UE 115.

[0067] Network entity 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hotspots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity used to communicate with network entity 105 (e.g., using a carrier) and may be associated with an identifier used to distinguish adjacent cells (e.g., Physical Cell Identifier (PCID), Virtual Cell Identifier (VCID), or other cell identifier). In some aspects, a cell may also refer to a coverage area 110 or a portion of coverage area 110 (e.g., a sector) on which a logical communication entity operates. Depending on various factors such as the capabilities of network entity 105, the extent of such cells may range from smaller areas (e.g., structures, subsets of structures) to larger areas. For example, a cell may be or may include buildings, subsets of buildings, or external space between or overlapping coverage areas 110, etc.

[0068] Macro cells typically cover a relatively large geographical area (e.g., a radius of several kilometers) and allow unrestricted access to UE 115 that has a service subscription with a network provider supporting the macro cell. In contrast, small cells can be associated with a lower-power network entity 105 (e.g., a lower-power base station 140) and can operate using the same or different (e.g., licensed or unlicensed) frequency bands as macro cells. Small cells can provide unrestricted access to UE 115 that has a service subscription with a network provider, or restricted access to UE 115 associated with a small cell (e.g., UE 115 in a Closed Subscriber Group (CSG), or UE 115 associated with a user in a home or office). Network entity 105 can support one or more cells and can also use one or more component carriers to support communication via one or more cells.

[0069] In some respects, a carrier can support multiple cells and can be configured with different cells based on different protocol types that can provide access for different types of devices (e.g., MTC, Narrowband IoT (NB-IoT), Enhanced Mobile Broadband (eMBB)).

[0070] In some aspects, network entity 105 (e.g., base station 140, RU 170) may be mobile, and thus provide communication coverage to mobile coverage areas 110. In some aspects, while different coverage areas 110 associated with different technologies may overlap, different coverage areas 110 may be supported by the same network entity 105. In some other examples, overlapping coverage areas 110 associated with different technologies may be supported by different network entities 105. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of network entities 105 use the same or different radio access technologies to provide coverage for various coverage areas 110.

[0071] The wireless communication system 100 can support synchronous or asynchronous operation. For synchronous operation, network entities 105 (e.g., base station 140) can have similar frame timing, and transmissions from different network entities 105 can be approximately time-aligned. For asynchronous operation, network entities 105 can have different frame timing, and in some respects, transmissions from different network entities 105 can be time-misaligned. The techniques described herein can be used for both synchronous and asynchronous operation.

[0072] Some UE 115 devices (such as MTC or IoT devices) can be low-cost or low-complexity devices and can provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC can refer to data communication technologies that allow devices to communicate with each other or with network entity 105 (e.g., base station 140) without human intervention. In some aspects, M2M communication or MTC may include communication from devices with integrated sensors or meters to measure or capture information and relay such information to a central server or application that uses the information or presents it to people interacting with the application. Some UE 115 devices may be designed to collect information or enable automated behavior of machines or other devices. Examples of applications for MTC devices include: smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geographic event monitoring, queue management and tracking, remote security sensing, physical access control, and transaction-based commercial charging.

[0073] Some UE 115s can be configured to operate in a power-saving mode, such as half-duplex communication (e.g., a mode that supports unidirectional communication via transmission or reception but does not involve concurrent transmission and reception). In some aspects, half-duplex communication can be performed at a reduced peak rate. Other power-saving techniques for UE 115s include: entering a power-saving deep sleep mode when not engaged in active communication, operating with limited bandwidth (e.g., according to narrowband communication), or a combination of these techniques. For example, some UE 115s can be configured to operate using a narrowband protocol type associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs)) within a carrier, within a carrier's guard band, or outside a carrier.

[0074] Wireless communication system 100 may be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, wireless communication system 100 may be configured to support ultra-reliable low-latency communication (URLLC). UE 115 may be designed to support ultra-reliable, low-latency, or critical functions. Ultra-reliable communication may include private or group communication and may be supported by one or more services, such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety or general business applications. The terms “ultra-reliable,” “low-latency,” and “ultra-reliable low-latency” are used interchangeably herein.

[0075] In some aspects, UE 115 may be configured to support direct communication with other UE 115s via device-to-device (D2D) communication link 135 (e.g., according to peer-to-peer (P2P), D2D, or sidelink protocols). In some aspects, one or more UEs 115s performing D2D communication in a group may be within the coverage area 110 of network entity 105 (e.g., base station 140, RU 170), which may support aspects of such D2D communication configured (e.g., scheduled) by network entity 105. In some aspects, one or more UEs 115s in such a group may be outside the coverage area 110 of network entity 105, or may otherwise be unable or not configured to receive transmissions from network entity 105. In some aspects, the group of UEs 115s communicating via D2D communication may support a one-to-many (1:M) system, wherein each UE 115 transmits to every other UE 115 in the group. In some respects, network entity 105 can facilitate the scheduling of resources for D2D communication. In some other examples, D2D communication can be performed between UEs 115 without involving network entity 105.

[0076] In some systems, the D2D communication link 135 may be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some aspects, vehicles may communicate using vehicle-to-vehicle (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these. Vehicles may signal information related to traffic conditions, signaling, weather, safety, emergencies, or any other information relevant to the V2X system. In some aspects, vehicles in a V2X system may communicate with roadside infrastructure such as roadside units, or communicate with the network via one or more network nodes (e.g., network entity 105, base station 140, RU 170) using vehicle-to-network (V2N) communication, or with both.

[0077] Core network 130 provides user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), and may include at least one control plane entity (e.g., a Mobility Management Entity (MME), Access and Mobility Management Function (AMF)) for managing access and mobility, and at least one user plane entity (e.g., a Serving Gateway (S-GW), Packet Data Network (PDN) Gateway (P-GW), or User Plane Function (UPF)) for routing packets or interconnecting to external networks. The control plane entity manages non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by network entity 105 (e.g., base station 140) associated with core network 130. User IP packets can be transferred through user plane entities, which provide IP address allocation and other functions. User plane entities may connect to one or more network operator IP services 150. IP services 150 may include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0078] Wireless communication system 100 can operate using one or more frequency bands in the range of 300 MHz to 300 GHz. Generally, the region from 300 MHz to 3 GHz is referred to as the Ultra High Frequency (UHF) region or decimeter band because the wavelength range is approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features (which may be referred to as clusters), but these waves are sufficient to penetrate structures so that macrocells can provide service to UE 115 located indoors. Compared to communication using smaller frequencies and longer waves in the High Frequency (HF) or Very High Frequency (VHF) portions of the spectrum below 300 MHz, communication using UHF waves can be associated with smaller antennas and shorter ranges (e.g., less than 100 km).

[0079] The wireless communication system 100 can also operate in the ultra-high frequency (SHF) region (also known as the centimeter band) in the range of 3 GHz to 30 GHz or in the extremely high frequency (EHF) region (e.g., 30 GHz to 300 GHz) (also known as the millimeter band) using the spectrum. In some aspects, the wireless communication system 100 can support millimeter-wave (mmW) communication between the UE 115 and the network entity 105 (e.g., base station 140, RU 170), and the EHF antennas of the corresponding devices can be smaller and more closely spaced compared to UHF antennas. In some aspects, such techniques facilitate the use of antenna arrays within the device. However, compared to SHF or UHF transmission, EHF transmission may experience even greater attenuation and a shorter range. The techniques disclosed herein can be adopted for transmission across one or more different frequency regions, and the frequency band usage specified across these frequency regions may vary by country or regulatory authority.

[0080] Wireless communication system 100 may utilize licensed and unlicensed RF spectrum bands. For example, wireless communication system 100 may use unlicensed frequency bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band) to employ Licensed Assisted Access (LAA), LTE Unlicensed (LTE-U) radio access technology, or NR technology. When operating using unlicensed RF spectrum bands, devices such as network entity 105 and UE 115 may employ carrier sensing for collision detection and avoidance. In some aspects, operations using unlicensed frequency bands may be combined with component carriers operating using licensed frequency bands based on carrier aggregation configurations (e.g., LAA). Operations using unlicensed spectrum may include downlink transmission, uplink transmission, P2P transmission, or D2D transmission, etc.

[0081] Network entity 105 (e.g., base station 140, RU 170) or UE 115 may be equipped with multiple antennas that can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of network entity 105 or UE 115 may be located within one or more antenna arrays or antenna panels, which can support MIMO operation or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly such as an antenna tower. In some aspects, the antennas or antenna arrays associated with network entity 105 may be located in different geographical locations. Network entity 105 may include an antenna array having a collection of multiple rows and columns of antenna ports that network entity 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may include one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals transmitted via the antenna ports.

[0082] Network entity 105 or UE 115 can use MIMO communication to leverage multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. This technique is known as spatial multiplexing. The multiple signals can be transmitted, 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 used for channel measurement and reporting. MIMO techniques include: single-user MIMO (SU-MIMO), for which multiple spatial layers are transmitted to the same receiving device; and multi-user MIMO (MU-MIMO), for which multiple spatial layers are transmitted to multiple devices.

[0083] Beamforming (also known as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., network entity 105, UE 115) to shape or guide an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array such that some signals propagating along a specific orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to the signals transmitted via the antenna elements may include applying amplitude shifts, phase shifts, or both to the signals carried via the antenna elements associated with the device. The adjustments associated with each of these antenna elements may be defined by a beamforming weight set associated with a specific orientation (e.g., relative to the antenna array of the transmitting or receiving device or relative to some other orientation).

[0084] Network entity 105 or UE 115 may use beam scanning technology as part of beamforming operations. For example, network entity 105 (e.g., base station 140, RU 170) may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times by network entity 105 along different directions. For example, network entity 105 may transmit signals according to different beamforming weight sets associated with different transmission directions. Transmission along different beam directions may be used to identify (e.g., by a transmitting device, such as network entity 105, or by a receiving device, such as UE 115) the beam direction for later transmission or reception by network entity 105.

[0085] Some signals (such as data signals associated with a specific receiving device) may be transmitted by a transmitting device (e.g., transmitting network entity 105, transmitting UE 115) along a single beam direction (e.g., the direction associated with the receiving device (such as receiving network entity 105 or receiving UE 115)).

[0086] In some respects, the beam direction associated with transmission along a single beam direction can be determined based on the signal transmitted along one or more beam directions. For example, UE 115 may receive one or more signals transmitted by network entity 105 in different directions and may report to network entity 105 an indication of signals received by UE 115 with the highest signal quality or other acceptable signal quality.

[0087] In some aspects, transmissions performed by a device (e.g., by network entity 105 or UE 115) may be performed using multiple beam directions, and the device may use a combination of digital pre-decoding or beamforming to generate a combined beam for transmission (e.g., from network entity 105 to UE 115). UE 115 may report feedback indicating pre-decoding weights for one or more beam directions, and this feedback may correspond to a configured beam set across the system bandwidth or one or more sub-bands. Network entity 105 may transmit reference signals (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)) that may or may not be pre-decoded. UE 115 may provide feedback for beam selection, which may be a pre-decoding matrix indicator (PMI) or codebook-based feedback (e.g., multi-panel codebook, linear combination codebook, port selection codebook). Although these techniques are described with reference to signals transmitted by network entity 105 (e.g., base station 140, RU 170) along one or more directions, UE 115 may use similar techniques to transmit signals multiple times along different directions (e.g., to identify the beam direction used by UE 115 for subsequent transmission or reception), or to transmit signals along a single direction (e.g., to transmit data to a receiving device).

[0088] A receiving device (e.g., UE 115) may perform reception operations according to multiple reception 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 reception directions by: receiving via different antenna subarrays; processing the received signals according to different antenna subarrays; receiving according to different sets of reception beamforming weights (e.g., different sets of directional listening weights) applied to signals received at multiple antenna elements of the antenna array; or processing the received signals according to different sets of reception beamforming weights applied to signals received at multiple antenna elements of the antenna array, any of which may refer to “listening” according to different reception configurations or reception directions. In some aspects, the receiving device may use a single reception configuration to receive along a single beam direction (e.g., when a data signal is received). A single receiver configuration can be aligned along a beam direction determined based on listening in different receiver 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 in multiple beam directions).

[0089] The wireless communication system 100 can be a packet-based network operating according to a layered protocol stack. In the user plane, communication at the bearer or PDCP layer can be IP-based. The RLC layer performs packet segmentation and reassembly for transmission via logical channels. The MAC layer performs priority handling and multiplexing of logical channels to transport channels. The MAC layer can also implement error detection, error correction, or both to support retransmission and improve link efficiency. In the control plane, the RRC layer provides the establishment, configuration, and maintenance of RRC connections between the UE 115 and network entity 105 or core network 130 that support user plane data radio bearers. The PHY layer maps transport channels to physical channels.

[0090] UE 115 and network entity 105 can support data retransmission to increase the likelihood of successful data reception. Hybrid Automatic Repeat Request (HARQ) feedback is a technique used to increase the likelihood of correctly receiving data via communication links (e.g., communication link 125, D2D communication link 135). HARQ may include a combination of error detection (e.g., using Cyclic Redundancy Check (CRC)), forward error correction (FEC), and retransmission (e.g., Automatic Repeat Request (ARQ)). HARQ can improve throughput at the MAC layer under poor radio conditions (e.g., low signal-to-noise ratio conditions). In some aspects, the device can support same-slot HARQ feedback, in which case the device can provide HARQ feedback in a specific time slot for data received via a previous symbol in that time slot. In some other examples, the device can provide HARQ feedback in subsequent time slots or according to a different time interval.

[0091] In some aspects, UE 115 can perform resource selection (e.g., sidelink resource selection, resource selection in Mode 2). Performing resource selection may include performing two steps. For example, the first step may include UE 115 identifying candidate resources through sensing and exclusion. The second step may include UE 115 performing candidate resource selection from the identified resources. In some aspects, higher layers of UE 115 can perform candidate resource selection.

[0092] To identify candidate resources in the first step, UE 115 can sense sidelink resources during the sensing window (e.g., when UE 115 is not transmitting). The sensing window can be defined by the time slot range [n-T0, NT]. proc,0 The time interval is defined as n, where n is the resource (re)selection trigger or time slot for selecting new resources, T0 is configured or pre-configured (e.g., 100 milliseconds (ms), 200 ms, 500 ms, 1000 ms, or 1100 ms), and T... proc,0This could be the time involved in completing the sensing process. Additionally, the first step could include UE 115 excluding candidate resources in a selection window (e.g., a selection window that appears after the sensing window). The selection window could include each resource within a time slot range [n-T1, n-T2], where T1 is the processing time involved in identifying candidate resources and selecting sidelink resources, and where T2 is the minimum value (e.g., T...). 2,min The range defined by the maximum value of the packet delay budget (PDB) and the maximum value of the packet delay budget (PDB). In some aspects, UE 115 may exclude any resources associated with resources in a time slot of the sensing window in which UE 115 transmits as part of half-duplex operation. Additionally, UE 115 may exclude candidate resources based on reservations made from other UEs (e.g., Phase 1 Side Link Control Information (SCI) detected during the sensing window). In some aspects, the first step may be performed in the PHY layer, and after identifying available candidate resources through sensing and exclusion, the PHY layer of UE 115 may report the available candidate resources to a higher layer of the UE (e.g., the MAC layer).

[0093] In some aspects, the second step may include a higher layer randomly selecting a sidelink resource from the available candidate resources reported by the UE 115 PHY. To select N candidate resources from the available candidate resources, the UE 115 may first randomly select one of the N candidate resources (e.g., a candidate resource in time slot m1). Additionally, the UE 115 may randomly select a second candidate resource, subject to the constraint that the gap between these second candidate resources must be less than a window W of 32 time slots. For example, the second candidate resource may be located within the time slot range [m...]. 1– (At time slot m2 within the range [32, m1+31]). If N is greater than 2, UE 115 can select a third candidate resource, subject to the constraint that the third candidate resource is located within the time slot range [m... 1– 32, m1+31] or [m 2– Time slots within [32, m2+31] m3 The above process can be repeated until all N candidate resources are selected.

[0094] If a higher layer (e.g., the MAC layer) of UE 115 requests UE 115 to determine a subset of resources from which the higher layer can select for transmission (e.g., Physical Side Link Shared Channel (PSSCH) transmission or Physical Side Link Control Channel (PSCCH) transmission) as part of a reassessment or preemption process, the higher layer (e.g., the UE MAC layer) can provide the set of resources that can be reassessed. , , , . . .) and the set of resources that can be seized ( , , . . .).

[0095] In some respects, reserved resources can be preempted by higher-priority reserved resources. If a resource meets one or more conditions, the UE PHY can report the preemption of the resource to a higher layer of the UE. For example, if the resource is preempted by another UE 115 (e.g., whose priority is...). Reserved, UE 115 can report preemption of resources. Additionally, if sl-PreemptiveEnable is equal to (for example, set to) "Enabled" and (For example, UE 115 has already reserved resources for its transmission priority) greater than Or if sl-PreemptiveEnable is not equal to (for example, not set to) "Enabled" and (For example, UE 115 has already reserved resources for its transmission priority) greater than and Then UE 115 can report preemption of resources. In some aspects, This can be a priority level configured by sl-PreemptiveEnable. In some respects, regarding priority values... , and Lower values ​​can correspond to higher priorities. If the UE PHY indicates that resources are reserved (e.g., A subset of resources can be used for preemption, and higher layers of UE 115 can remove them. There are several resources, and you can randomly select from available candidate resources within the new selection window. A new candidate resource.

[0096] In some examples, preemptible resources can be defined as described herein. For example, UE 115 can report a set to higher layers. (For example, a collection of resources). If resources (from collection () , , , . . .))no If a member is a member, then UE 115 can report the resource to a higher layer. A reassessment of resources. (from collection () , If one or more conditions are met, UE 115 can report resource requests to a higher layer. The seizure. For example, if no Members; if Satisfy according to the threshold (e.g.) One or more exclusion conditions; and if sl-PreemptionEnable equals "Enabled", Or when sl-PreemptionEnable is not equal to "Enabled", and .

[0097] In shared spectrum (e.g., unlicensed sidelink spectrum), UEs can transmit MCSts, which can improve channel utilization efficiency. Similar to licensed bands, a UE's reserved resources may be preempted by another higher-priority UE. The reserved resources preempted by the higher-priority UE may be within the lower-priority UE's MCSt (e.g., may include non-edge resources of the MCSt). In such examples, the lower-priority UE may lose Channel Occupancy Time (COT), and the higher-priority UE may be unable to contend for the channel. If, after a higher-priority UE preempts a reserved resource, the lower-priority UE's reserved resource has a higher priority than the higher-priority UE's reserved resource, the lower-priority UE may be unable to transmit higher-priority services due to losing COT.

[0098] The techniques described herein enhance MCSt in shared spectrum (e.g., unlicensed sidelinks). For example, the techniques described herein may include higher layers indicating contiguous groups of resources available for preemption (e.g., instead of just indicating a single resource). Additionally or alternatively, the techniques described herein may include enhanced conditions for the UE PHY to report resource preemption to the higher layers of UE 115 (e.g., using the priority of MCSt as these conditions). Additionally or alternatively, the techniques described herein may include enhanced behavior of the UE PHY and / or the higher layers of UE 115 that report preemption after receiving a preemption indication (e.g., the UE PHY reports MCSt resources instead of just a single resource).

[0099] Figure 2 Examples of a wireless communication system 200 supporting enhanced preemption for multi-slot transmission according to one or more aspects of this disclosure are illustrated. In some aspects, the wireless communication system 200 may implement one or more aspects of the wireless communication system 100. For example, UEs 115-a and 115-b may be as described in the reference. Figure 1 Examples of UE 115 described herein. In some respects, UE 115-a may be referred to as UE1, and UE 115-b may be referred to as UE2.

[0100] UEs 115-a and 115-b can perform sidelink communication. In some aspects, UE 115-a can reserve resources 215 of selection window 202 (e.g., including resources 215-a and 215-b), and UE 115-b can reserve resources 225 of selection window 202. Additionally, selection window 202 can include excluded resources 230 that UE 115-a cannot use. In some aspects, UE 115-a can determine preemption of reserved resources 215. For example, UE 115-a can select a first set of consecutive resources (resources 215-a, 215-b, and 235) in selection window 202 to send a first message (e.g., MCSt), wherein each resource in selection window 202 can be defined according to one or more time slots 210 and one or more sub-channels 205. However, UE 115-b may reserve a first resource (e.g., resource 235, which may be indicated in the SCI of UE 115-b) for the second message, which may overlap with the first group of consecutive resources.

[0101] In some respects, UE 115-a can determine whether to report preemption of the first resource based on one or more conditions. In the first preemption condition scheme, if one or more single-slot resources of UE 115-a's MCSt in a multi-slot resource are reserved by UE 115-b, UE 115-a can determine whether each resource (e.g., resource 235) in the one or more single-slot resources will be preempted based on the transmission priority of UE 115-b on each single-slot resource compared to the priority of the MCSt on the single-slot resource. For example, in this example, the first priority of the first message on resource 235 may have a value... Furthermore, the second message may have a value on resource 235 with a second priority. If the preemption enable parameter (e.g., sl-PreempyEnable) is equal to (e.g., set to) "Enabled" and Greater than Or if the preemption enable parameter (e.g., sl-PreempyEnable) is not equal to (e.g., not set to) "Enabled" and Greater than and Then UE 115-a can report preemption of resources. In some aspects, regarding priority values... , and Lower values ​​can correspond to higher priorities. For example, priority values... , and It can be the Channel Access Priority Class (CAPC) value.

[0102] In the second preemption condition scheme, if one or more single-slot resources in the multi-slot resources of UE 115-a's MCSt are reserved by UE 115-b, UE 115-a can determine whether all single-slot resources (e.g., resource 235) in the one or more single-slot resources in the multi-slot resources will be preempted based on the priority of the MCSt relative to the priority associated with one or more transmissions of UE 115-b on the one or more single-slot resources. For example, in this example, the first priority of UE 115-a's MCSt (e.g., ... ) and UE 115-b's second priority on one or more single-slot resources (e.g., The comparison is as follows. In one aspect, UE 115-a may report preemption for each of one or more single-slot resources (e.g., the entire multi-slot resource for MCSt) based on the following condition: if preemption for MCSt is equal to (e.g., set to) "Enabled" and Greater than ; or if preemption of MCSt is not equal to (not set to) "enabled" and if Greater than And if ,in This can be a priority level configured by Radio Resource Control (RRC) (e.g., CAPC value). In some respects, UE 115-b may reserve one or more single-slot resources to transmit UE 115-b's MCSt, or may reserve one or more single-slot resources for separate transmission.

[0103] In some aspects, the first and second preemption condition schemes for determining whether to report preemption can each determine whether a first preemption enabling parameter (e.g., sl-PreemptionEnable) is equal to (e.g., set to) "Enabled" (e.g., the first and second preemption condition schemes can share the same parameter). Alternatively, the first preemption condition scheme can use the first preemption enabling parameter (e.g., sl-PreemptyEnable), and the second preemption condition scheme can determine whether to report preemption by determining whether a second preemption enabling parameter (e.g., MCSt preemption enabling parameter) different from the first preemption enabling parameter (e.g., sl-PreemptyEnable) is equal to (e.g., set to) "Enabled". In some aspects, Can be equal to In such examples, It can be pre-configured, and Available from OK. In other examples, and They can have different values. In this case, they can be configured separately. and In some examples, for and A lower value can have a higher priority. For example, and It can be a CAPC priority value.

[0104] In some respects, one or more time slots in a multi-time slot resource may be associated with different priorities (e.g., the MCSt on resource 215-a may be associated with a different priority than the MCSt on resource 235). In a first priority determination scheme, UE 115-a may select the highest priority among all single-time slot resources in the single-time slot resources of the MCSt (e.g., the highest priority among the priorities associated with each resource in the multi-time slot resources, such as each resource in resources 215-a, 215-b, and 235). Alternatively, in a second priority determination scheme, UE 115-a may select the highest priority among all single-time slot resources in the MCSt that overlap with resources reserved by another UE (e.g., any other UE with overlapping resources detected by UE 115-b and UE 115-a). Alternatively, in the third priority determination scheme, UE 115-a may select the highest priority among all single-slot resources in the MCSt that overlap with resources reserved only by UE 115-b (e.g., without considering resources of other UEs that overlap with single-slot resources in the MCSt besides UE 115-b). This document may refer to, for example, […]. Figure 4 and Figure 5 Describe additional aspects of the prioritization scheme.

[0105] After determining that one or more single-slot resources (e.g., the first resource, resource 235) will be preempted, the PHY layer of UE 115-a may report the one or more single-slot resources to a higher layer of UE 115-a (e.g., the MAC layer). In some aspects, the PHY of UE 115-a may report preemption for each single-slot resource (e.g., UE 115-a may provide a separate indication for each single-slot resource). In other examples, the PHY of UE 115-a may report preemption for the entire multi-slot resource of MCSt (e.g., UE 115-a may provide a single indication for the multi-slot resource). In one aspect, a single bit may be used to indicate that one or more single-slot resources in the multi-slot resource of MCSt have been preempted. In another example, a bitmap may be used to indicate which resource in the multi-slot resource of MCSt has been preempted. In yet another example, UE 115-a may report a single preemption at the first preempted single-slot resource in the multi-slot resource of MCSt. After reporting one or more single-slot resources to a higher layer, the higher layer may perform resource selection (e.g., the higher layer may select multi-slot resource 220 to send MCSt).

[0106] In some aspects, before the UE determines whether to report preemption of a first resource overlapping with the first set of contiguous resources, a higher layer (e.g., the MAC layer) may indicate a set of resources available for preemption (e.g., preemptible). In some aspects, the higher layer may provide a single-slot set of preemptible resources. In other examples, the higher layer may provide a multi-slot set of preemptible resources. This document may refer to, for example, […]. Figure 3A and Figure 3B Describe additional aspects of how higher levels direct resource sets.

[0107] In some respects, the techniques described herein can be associated with one or more advantages. For example, indicating a set of multi-slot resources at a higher layer can be associated with reduced overhead (e.g., involving fewer bits being transmitted) compared to indicating a single resource within a multi-slot resource. Additionally, determining whether preemption should occur based on a comparison of one priority of the MCSt with other different priorities of the MCSt prevents UE 115-a from reporting preemption when a preemption condition is met for one resource of the MCSt, but another resource of the MCSt is associated with a priority that would cause the preemption condition to fail. Therefore, UE 115-a can maintain COT during the period when the preemption condition is met for that one resource.

[0108] Figure 3A and Figure 3BExamples of preemption resource indication schemes 300-a and 300-b supporting enhanced preemption for multi-continuous time-slot transmission according to one or more aspects of this disclosure are illustrated. In some aspects, preemption resource indication schemes 300-a and 300-b may be implemented by one or more aspects of wireless communication systems 100 and / or 200, and / or one or more aspects of wireless communication systems 100 and / or 200 may be implemented. For example, resource indication schemes 300-a and 300-b may be depicted as referenced. Figure 2 The selection window 202 is described. Additionally or alternatively, each resource in resource indication schemes 300-a and 300-b may be defined by one or more time slots 310 and one or more sub-channels 305, which may be as referenced... Figure 2 Examples of time slot 210 and / or sub-channel 205 described herein. In some aspects, the selected resource 315 may be as described in the reference. Figure 2 The example described is resource 215, and resource 320 has been excluded as shown in the reference. Figure 2 The example described is the excluded resource 230.

[0109] For reference Figure 3A The described UE (e.g., as referenced) Figure 2 The UE 115-a described or as referenced Figure 1 The higher layer of the described UE 115 can provide the UE's PHY layer with a set 315 of preemptible single-slot resources. For example, the higher layer of the UE can provide a set ( , , , , .. . .),in This corresponds to resource 315-a. This corresponds to resource 315-b. It can correspond to resource 315-c, and This corresponds to resource 315-d. Therefore, resources 315-a, 315-b, 315-c, and 315-d can be preempted as part of the resource selection process. In some aspects, resources 315-e and 315-f may not be indicated as preemptible. Therefore, resources 315-e and 315-f cannot be preempted as part of the resource selection process.

[0110] For reference Figure 3B As depicted, the higher layers of the UE can provide the UE's PHY layer with a set of preemptible multi-slot resources 325. For example, the higher layers of the UE can provide a set ( , , , . . .),in This can correspond to multi-timeslot resource 325-a. It can correspond to multi-timeslot resource 325-b, and This can correspond to multi-timeslot resource 325-c. In some aspects, multi-timeslot resource 325-a may include resources 315-a and 315-b; multi-timeslot resource 325-b may include resources 315-c and 315-e, and multi-timeslot resource 325-c may include resources 315-d and 315-f. Therefore, each of resources 315-a to 315-f can be preempted.

[0111] Figure 4 An example is illustrated of a resource selection scheme 400 supporting enhanced preemption for multi-slot transmission according to one or more aspects of this disclosure. In some aspects, the resource selection scheme 400 may be implemented by one or more aspects of the wireless communication system 100 and / or 200, and / or may be implemented by one or more aspects of the wireless communication system and / or 200. For example, the resource selection scheme 400 may depict a selection window 402, which may be as shown in the reference... Figure 2 An example of the selection window 202 described herein. Additionally or alternatively, each resource in resource selection scheme 400 may be defined by one or more time slots 410 and one or more sub-channels 405, the time slots and sub-channels being as described in reference [reference needed]. Figure 2 Examples of time slot 210 and / or sub-channel 205 described herein. In some aspects, the selected resource 415 may be as described in the reference. Figure 2 Examples of described resource 215 (e.g., selected resources of UE 115-a); resource 425 may be as referenced Figure 2 Examples of described resource 225 (e.g., selected and / or reserved resources of UE 115-b); resource 430 may be as referenced Figure 2 The example described excludes resource 230; and resource 435 can be as referenced. Figure 2 Examples of the described resource 235 (e.g., selected and / or reserved resources for UE115-a and 115-b).

[0112] Resource selection scheme 400 may include a sensing window 401 and a selection window 402. The sensing window can be in time... It starts at [location], and can be [time]. End here. Select window 402 to view the time. It starts at [location], and can be [time]. The process ends here. In some respects, T1 is the processing time involved in identifying candidate resources and selecting sidelink resources, and T2 is the minimum value (e.g., T...). 2,minThe range defined by the maximum value of PDB. In some aspects, the UE can use sensing window 401 to sense candidate resources available for selection, and the UE can use selection window 402 to schedule resources for sending messages.

[0113] In this example, the first UE (e.g., as referenced) Figure 2 The described UE 115-a) may select resource 415 for transmitting a first message (e.g., MCSt). These resources may be part of a first multi-timeslot resource (e.g., MCS resource). For example, resources may be temporally contiguous and there may be multiple resources. In this example, the first resource 415 in the multi-timeslot resources of the first UE may be associated with priority level 1; the second resource 415 in the multi-timeslot resources of the first UE may be associated with priority level 5; and the third resource 415 in the multi-timeslot resources of the first UE may be associated with priority level 3, where a lower priority value indicates a higher priority. Additionally, the second UE (e.g., as referenced) Figure 2 The described UE 115-b) may select and / or reserve resource 425 to send a second message (e.g., MCSt). In some aspects, these resources may be part of a second multi-timeslot resource (e.g., MCS resource). In this example, the first resource 425 in the multi-timeslot resources of the second UE may be associated with priority level 3; the second resource 425 in the multi-timeslot resources of the second UE may be associated with priority level 2; and the third resource 425 in the multi-timeslot resources of the second UE may be associated with priority level 2.

[0114] In some aspects, the resources used to send the first message can be mapped to the same resources in selection window 402 used to send the second message. For example, in this example, the first multi-timeslot resource and the second multi-timeslot resource can overlap to form resource 435. For example, the second and third resources 415 in the first multi-timeslot resource can overlap with the first and second resources 425 in the second multi-timeslot resource UE, respectively, to form the first overlapping resource 435 and the second overlapping resource 435. Additionally, the first resource 415 in the first multi-timeslot resource and the third resource 425 in the second multi-timeslot resource may not overlap with any resources in the second and first multi-timeslot resources, respectively.

[0115] In some respects, the first UE may determine whether to perform preemption based on the overlap between the resources used to send the first message and the resources used to send the second message. According to this document (e.g., regarding...), Figure 2 The first preemption condition scheme described herein, the second resource 415 in the first multi-slot resource. It can be 5, and the first resource 425 in the second multi-slot resource. It can be 3. Since for the first overlapping resource 435, (For example, and assuming the preemptive enable parameter is equal to "Enable", or the preemptive enable parameter is equal to "Disable" and) The first UE can report preemption of the first overlapping resource 435. Additionally, according to the first preemption condition scheme described herein, the third resource 415 in the first multi-slot resource... It can be 3, and the second resource 425 in the second multi-slot resource. It can be 2. Since for the second overlapping resource 435, (For example, and assuming the preemptive enable parameter is equal to "Enable", or the preemptive enable parameter is equal to "Disable" and) The first UE can report preemption of the second overlapping resource 435.

[0116] In other examples, according to this article (e.g., regarding...) Figure 2 The first priority determination scheme of the second preemption condition scheme described in the first multi-slot resource, the second resource 415. It can be And the first resource 425 in the second most time slot resources It can be For the first overlapping resource 435, The first UE may not report preemption of the first overlapping resource 435. Additionally, according to this document (e.g., regarding...), Figure 2 The first priority determination scheme of the second preemption condition scheme described in the first multi-slot resource, the third resource 415. It can be And the second resource 425 in the second multi-slot resource It can be For the second overlapping resource 435, The first UE may not report preemption of the second overlapping resource 435.

[0117] In other examples, according to this article (e.g., regarding...) Figure 2 The second priority determination scheme of the second preemption condition scheme described in the first multi-slot resource is the second resource 415. It can be And the first resource 425 in the second most time slot resources It can be For the first overlapping resource 435, (For example, and assuming the preemptive enable parameter is equal to "Enable", or the preemptive enable parameter is equal to "Disable" and) The first UE may report preemption of the first overlapping resource 435. Additionally, according to this document (e.g., regarding...), Figure 2 The second priority determination scheme of the second preemption condition scheme described in the first multi-slot resource is the third resource 415. It can be And the second resource 425 in the second multi-slot resource It can be For the second overlapping resource 435, (For example, and assuming the preemptive enable parameter is equal to "Enable", or the preemptive enable parameter is equal to "Disable" and) The first UE can report preemption of the second overlapping resource 435.

[0118] In other examples, according to this article (e.g., regarding...) Figure 2 The third priority determination scheme of the second preemption condition scheme described in the first multi-slot resource is the second resource 415. It can be And the first resource 425 in the second most time slot resources It can be For the first overlapping resource 435, (For example, and assuming the preemptive enable parameter is equal to "Enable", or the preemptive enable parameter is equal to "Disable" and) The first UE may report preemption of the first overlapping resource 435. Additionally, according to this document (e.g., regarding...), Figure 2 The third priority determination scheme of the second preemption condition scheme described in the first multi-slot resource is the third resource 415. It can be And the second resource 425 in the second multi-slot resource It can be For the second overlapping resource 435, (For example, and assuming the preemptive enable parameter is equal to "Enable", or the preemptive enable parameter is equal to "Disable" and) The first UE can report preemption of the second overlapping resource 435.

[0119] If the first UE reports preemption of the first overlapping resource 435 and / or the second overlapping resource 435 (e.g., if the preemption conditions are met), the first UE may select a new resource 420 in selection window 402 to send the first message. If the first UE does not report preemption of the first overlapping resource 435 and the second overlapping resource 435, the first UE may send the first message on the initially selected resource (e.g., the first resource 415 in the first multi-slot resource and the first overlapping resource and the second overlapping resource 435).

In some aspects, the resource selection scheme 500 may be implemented by one or more aspects of the wireless communication system 100 and / or 200, and / or may be implemented by one or more aspects of the wireless communication system and / or 200. For example, the resource selection scheme 500 may depict a selection window 502, which may be as shown in the reference... Figure 2 An example of the selection window 202 described herein.

Select window 502 to view the time. It starts at [location], and can be [time]. The process ends here. In some respects, T1 is the processing time involved in identifying candidate resources and selecting sidelink resources, and T2 is the minimum value (e.g., T...). 2,min The range defined by the maximum value of PDB. In some aspects, the UE can use sensing window 501 to sense candidate resources available for selection, and the UE can use selection window 502 to schedule resources for sending messages.

[0122] In this example, the first UE (e.g., as referenced) Figure 2The described UE 115-a) can select resources 515 for transmitting a first message (e.g., MCSt). These resources may be part of a first multi-timeslot resource (e.g., MCS resource). For example, the resources may be temporally contiguous and there may be multiple resources. In this example, the first resource 515 in the multi-timeslot resources of the first UE may be associated with priority level 1; the second resource 515 in the multi-timeslot resources of the first UE may be associated with priority level 5; and the third resource 515 in the multi-timeslot resources of the first UE may be associated with priority level 3. Additionally, the second UE (e.g., as referenced) Figure 2 The described UE 115-b) may select and / or reserve resource 525 to send a second message (e.g., MCSt). In some aspects, these resources may be part of a second multi-timeslot resource (e.g., MCS resource). In this example, the first resource 525 in the multi-timeslot resource of the second UE may be associated with priority level 3, and the second resource 525 in the multi-timeslot resource of the second UE may be associated with priority level 2. Additionally, a third UE (e.g., as referenced) may also reserve resource 525. Figure 1 The described UE 115 may choose and / or reserve resource 540 to send a third message. In some respects, resource 540 may be associated with priority level 3.

[0123] In some aspects, resources used to send a first message may be mapped to the same resources in selection window 502 used to send a second message and / or resources used to send a third message. For example, resources 540 of the first multi-timeslot resource and the third UE may overlap to form a first overlapping resource 545. For example, resources 515 in the first multi-timeslot resource may overlap with resources 540 of the third UE to form a first overlapping resource 545. Additionally, resources 515 in the first multi-timeslot resource may overlap to form a second overlapping resource 535. For example, resources 515 in the first multi-timeslot resource may overlap with resources 525 of the second multi-timeslot resource UE to form a second overlapping resource 535. Additionally, resources 515 in the first multi-timeslot resource and resources 525 in the second multi-timeslot resource may not overlap with any resources in the second or first multi-timeslot resource, or with any resources in resources 540 of the third UE.

[0124] In some respects, the first UE may determine whether to perform preemption based on the overlap between resources used to send the first message and resources used to send the second message and / or the third message. According to this document (e.g., regarding...), Figure 2 The first preemption condition scheme described herein, the second resource 515 in the first multi-slot resource. It can be 5, and the third UE's resources are 540. It can be 3. Since for the first overlapping resource 545, (For example, and assuming the preemptive enable parameter is equal to "Enable", or the preemptive enable parameter is equal to "Disable" and) The first UE can report preemption of the first overlapping resource 545. Additionally, according to the first preemption condition scheme described herein, the third resource 515 in the first multi-slot resource... It can be 3, and the first resource 525 in the second multi-slot resource. It can be 3. Since for the second overlapping resource 535, Not greater than The first UE may not report preemption of the second overlapping resource 535.

[0125] In other examples, according to this article (e.g., regarding...) Figure 2 The first priority determination scheme of the second preemption condition scheme described in the first multi-slot resource, the second resource 515. It can be And the third UE's resources are 540. It can be For the first overlapping resource 545, The first UE may not report preemption of the first overlapping resource 545. Additionally, according to this document (e.g., regarding...), Figure 2 The first priority determination scheme of the second preemption condition scheme described in the first multi-slot resource, the third resource 515. It can be And the first resource 525 in the second most time slot resources It can be For the second overlapping resource 535, The first UE may not report preemption of the second overlapping resource 535.

[0126] In other examples, according to this article (e.g., regarding...) Figure 2 The second priority determination scheme of the second preemption condition scheme described in the first multi-slot resource is the second resource 515. It can be And the third UE's resources are 540. It can be For the first overlapping resource 545, Not greater than The first UE may not report preemption of the first overlapping resource 545. Additionally, according to this document (e.g., regarding...), Figure 2 The second priority determination scheme of the second preemption condition scheme described in the first multi-slot resource is the third resource 515. It can be And the first resource 525 in the second most time slot resources It can be For the second overlapping resource 535, (For example, and assuming the preemptive enable parameter is equal to "Enable", or the preemptive enable parameter is equal to "Disable" and) The first UE can report preemption of the second overlapping resource 535.

[0127] In other examples, according to this article (e.g., regarding...) Figure 2 The third priority determination scheme of the second preemption condition scheme described in the first multi-slot resource is the second resource 515. It can be And the third UE's resources are 540. It can be For the first overlapping resource 545, (For example, and assuming the preemptive enable parameter is equal to "Enable", or the preemptive enable parameter is equal to "Disable" and) The first UE may report preemption of the first overlapping resource 545. Additionally, according to this document (e.g., regarding...), Figure 2 The third priority determination scheme of the second preemption condition scheme described in the first multi-slot resource is the third resource 515. It can be And the first resource 525 in the second most time slot resources It can be For the second overlapping resource 535, Not greater than The first UE may not report preemption of the second overlapping resource 535.

[0128] If the first UE reports preemption of the first overlapping resource 545 and / or the second overlapping resource 535 (e.g., if the preemption conditions are met), the first UE may select a new resource 520 in selection window 502 to send the first message. If the first UE does not report preemption of the first overlapping resource 545 and the second overlapping resource 535, the first UE may send the first message on the initially selected resource (e.g., the first resource 415, the first overlapping resource 545, and the second overlapping resource 535 in the first multi-timeslot resource).

[0129] Figure 6 An example of a process flow 600 supporting enhanced preemption for multi-slot transmission according to one or more aspects of this disclosure is illustrated. In some aspects, process flow 600 may be implemented by one or more aspects of wireless communication systems 100 and / or 200. For example, UE115-c may be as described in reference...

In some respects, higher layer 605 may represent a higher layer of UE 115-c (e.g., the MAC layer), and UE PHY 610 may represent the PHY layer of UE 115-c.

[0130] At 620, the higher layer 605 may provide the UE PHY 610 with an indication of a set of resources available for preemption. In some aspects, this indication of the set of resources includes an indication of one or more sets of consecutive resources. In some aspects, the indication of the set of resources available for preemption includes a separate indication of each resource in the set, wherein each resource in the set spans one time slot.

[0131] At 625, UE 115-c can select a first set of continuous resources for sending the first message, wherein the first set of continuous resources overlaps with the first resource in the set of resources available for preemption.

[0132] At 630, UE 115-c can determine that the second UE has reserved the first resource in the resource set (e.g., UE 115-c can receive the SCI for scheduling the first resource from the second UE).

[0133] At 635, UE PHY 610 may report to higher layer 605 an indication that the first resource is being preempted, based on the received indication that the second UE has reserved the first resource in the resource set. In some aspects, the report may be based on a first priority of a second message from which the second UE has reserved the first resource, the first priority being relative to a second priority of the portion of the message corresponding to a time slot that overlaps with the first resource in time. In some aspects, the report is based on the first priority of the second message from which the second UE has reserved the resource, the first priority being relative to the priority of the message on the first set of contiguous resources. In some aspects, the report includes an indication of preemption for each resource in a subset of the resource set, the subset including the first resource and second resources in the resource set that overlap with the first set of contiguous resources. In some aspects, the report includes an indication that the first set of contiguous resources has been preempted. In some aspects, the report is based on the second priority being higher than the first priority. Alternatively, the report is based on the second priority being lower than the first priority. In some aspects, UE 115-c can determine that UE 115-c has disabled preemption of the first group of continuous resources and can receive an indication of a third priority via RRC signaling, wherein the report is based on the second priority being higher than the third priority and determining that UE 115-a has disabled preemption of the first group of continuous resources. In some aspects, the second priority includes the highest priority in the priority set of the message, each priority in the priority set corresponding to a corresponding resource in a subset of the resource set available for preemption, the subset of the resource set including resources reserved by the second UE and overlapping with the first group of continuous resources. In some aspects, the second priority includes the highest priority in the priority set, wherein each priority in the priority set corresponds to a corresponding resource in the subset of the first group of continuous resources of the first message, and wherein each resource in the subset of the first group of continuous resources overlaps with a corresponding resource in the resource set reserved by the second UE.

[0134] At 640, UE 115-c may, based on this report, transmit the first message on a second set of continuous resources different from the first set of continuous resources. In some aspects, the first set of continuous resources overlaps in time and frequency with at least one resource in the set of resources available for preemption, and the second set of continuous resources does not overlap in time and frequency with the first resource. In some aspects, the first priority and the second priority may each be associated with a different Channel Access Priority Class (CAPC) (e.g., a lower CAPC value may correspond to a higher priority).

[0174] According to the examples disclosed herein, the communication manager 1020 may support wireless communication at a first UE. For example, the communication manager 1020 may be configured as, or otherwise support, a component for: receiving, at a first layer of the first UE and from a second layer of the first UE, an indication of a set of resources available for preemption, wherein the indication of the resource set includes an indication of one or more sets of consecutive resources. The communication manager 1020 may be configured as, or otherwise support, a component for: selecting a first set of consecutive resources for sending a message, wherein the first set of consecutive resources overlaps with a first resource in the set of resources available for preemption. The communication manager 1020 may be configured as, or otherwise support, a component for: receiving an indication that a second UE has reserved the first resource in the resource set. The communication manager 1020 may be configured as, or otherwise support, a component for: reporting from the first layer to the second layer, based on the received indication that the second UE has reserved the first resource in the resource set, an indication that the first resource is being preempted. The communication manager 1020 can be configured as, or otherwise supported as, a component for sending the message on a second set of continuous resources that is different from the first set of continuous resources, based on the report.

[0175] Additionally or alternatively, according to the examples disclosed herein, the communication manager 1020 may support wireless communication at the first UE. For example, the communication manager 1020 may be configured as or otherwise support a component for receiving, at a first layer of the first UE and from a second layer of the first UE, an indication of a set of resources available for preemption. The communication manager 1020 may be configured as or otherwise support a component for selecting a first set of consecutive resources for sending a first message, wherein the first set of consecutive resources overlaps with a first resource in the set of resources available for preemption. The communication manager 1020 may be configured as or otherwise support a component for receiving an indication from a second UE that the first resource in the set has been reserved. The communication manager 1020 may be configured as, or otherwise support, a component for performing the following operations: based on the indication received that the second UE has reserved the first resource in the resource set and a first priority of the second message for which the second UE has reserved the first resource, reporting from the first layer to the second layer an indication that the first resource is being preempted, the first priority being relative to the second priority of the first message on the first group of consecutive resources. The communication manager 1020 may also be configured as, or otherwise support, a component for performing the following operations: based on the report, transmitting the first message on a second group of consecutive resources different from the first group of consecutive resources.

[0176] By including or configuring a communication manager 1020 according to an example as described herein, device 1005 can support related technologies that enable a UE to avoid reporting preemption in a scenario where the priority of MCSt in a time slot overlapping with the transmission of another UE is lower than the priority of MCSt in another time slot, thereby enabling the UE to maintain COT.

[0177] In some aspects, the communication manager 1020 may be configured to use or otherwise coordinate with the transceiver 1015, one or more antennas 1025, or any combination thereof to perform various operations (e.g., receiving, monitoring, transmitting). Although the communication manager 1020 is illustrated as a separate component, in some aspects, one or more functions described with reference to the communication manager 1020 may be supported or performed by the processor 1040, memory 1030, code 1035, or any combination thereof.
