Techniques for prioritizing communications for sidelink communications

Abstract

Methods, systems, and apparatus for wireless communications are described for prioritizing sidelink communications of a user equipment (UE) having one or more access link communications. A prioritization scheme may provide inter-UE and intra-UE prioritization that may be used to prioritize sidelink communications and one or more access link communications. Inter-UE prioritization may be used at a UE to determine whether to cancel all or part of a sidelink communication that uses resources indicated in a cancellation indication from a base station, or to send the sidelink communication regardless of the cancellation indication. In the event of resource overlap between access link and sidelink communications, intra-UE prioritization may be used at a UE to determine which of one or more access link communications or sidelink communications to maintain or cancel.

[0002] This patent application claims the benefit of U.S. Provisional Patent Application No. 63 / 008,582, filed on April 10, 2020 by Zhang et al., entitled “Techniques for Prioritizing Communication for Sidelink Communications,” and U.S. Patent Application No. 17 / 224,930, filed on April 7, 2021 by Zhang et al., entitled “Techniques for Prioritizing Communication for Sidelink Communications,” each of which is assigned to the assignee of this Agreement. Technical Field

[0003] The following relates generally to wireless communications and, more particularly, to techniques for prioritizing communications for sidelink communications. Background Art

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasting, etc. 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, advanced LTE (LTE-A) systems, or LTE-APro systems, and fifth generation (5G) systems that may be referred to as new radio (NR) systems. These systems may use techniques such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (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 or one or more network access nodes, each base station or network access node simultaneously supporting communication for multiple communication devices, which may also be referred to as user equipment (UE).

[0005] Some wireless communication systems may support both access links and side links. Access links are communications links between UEs and base stations. In some examples, access links may be referred to as Uu interfaces. Specifically, Uu interfaces may be referred to as air interfaces for downlink transmissions, uplink transmissions, or both. Side links are communications links between similar devices, and in some cases, may be referred to as PC5 interfaces. For example, side links may support communications between multiple UEs (e.g., in other examples, in vehicle-to-everything (V2X) systems, vehicle-to-vehicle (V2V) systems, device-to-device (D2D) systems). Effective and reliable techniques for managing access link communications and side link communications may be required. Summary of the invention

[0006] The described technology relates to improved methods, systems, devices and apparatuses for supporting technologies for prioritizing communications for sidelink communications. According to various aspects, a user equipment (UE) may be configured for sidelink communications, and sidelink communications and access link communications may be prioritized according to a prioritization scheme. In some cases, the UE may receive an uplink cancellation indication (CI) from a base station, which indicates that at least a portion of the radio resources configured for sidelink communications will be used for high-priority communications at the base station (e.g., for high-priority communications with another UE). The prioritization scheme may include inter-UE prioritization, which may be used at the UE to determine whether to cancel all or part of the sidelink communications using the resources indicated in the CI, or to send the sidelink communications regardless of the CI. In some cases, additionally or alternatively, the prioritization scheme may include intra-UE prioritization, which may be used at the UE to determine which of the access link communications or sidelink communications to maintain or cancel in the case of resource overlap between the access link and the sidelink communications.

[0007] A method for wireless communication at a first UE is described. The method may include identifying a first set of resources for a first sidelink communication with a second UE, wherein the first sidelink communication has a first priority; receiving a first indication of a second set of resources for a second communication, the second communication having a second priority, wherein the second set of resources at least partially overlaps with the first set of resources; receiving a second indication of a third set of resources for a third communication, the third communication having a third priority; and determining to drop or send the first sidelink communication based on a priority ordering scheme associated with the first priority, the second priority, and the third priority.

[0008] An apparatus for wireless communication at a first UE is described. The apparatus may include a processor, a memory coupled to the processor, and instructions stored in the memory. The instructions may be executed by the processor to cause the apparatus to identify a first set of resources for a first sidelink communication with a second UE, wherein the first sidelink communication has a first priority; receive a first indication of a second set of resources for a second communication, the second communication having a second priority, wherein the second set of resources at least partially overlaps with the first set of resources; receive a second indication of a third set of resources for a third communication, the third communication having a third priority; and determine to stop or send the first sidelink communication based on a priority sorting scheme associated with the first priority, the second priority, and the third priority.

[0009] Another apparatus for wireless communication at a first UE is described. The apparatus may include a component for identifying a first set of resources for a first sidelink communication with a second UE, wherein the first sidelink communication has a first priority; receiving a first indication of a second set of resources for a second communication, the second communication having a second priority, wherein the second set of resources at least partially overlaps with the first set of resources; receiving a second indication of a third set of resources for a third communication, the third communication having a third priority; and determining to stop or send the first sidelink communication based on a priority ordering scheme associated with the first priority, the second priority, and the third priority.

[0010] A non-transitory computer-readable medium is described, storing code for wireless communication at a first UE. The code may include instructions executed by a processor to perform the following operations: identifying a first set of resources for a first sidelink communication with a second UE, wherein the first sidelink communication has a first priority; receiving a first indication of a second set of resources for a second communication, the second communication having a second priority, wherein the second set of resources at least partially overlaps with the first set of resources; receiving a second indication of a third set of resources for a third communication, the third communication having a third priority; and determining to stop or send the first sidelink communication based on a priority ordering scheme associated with the first priority, the second priority, and the third priority.

[0011] In some examples of the methods, apparatus, and non-transitory computer-readable media described herein, the prioritization scheme provides a priority between a first sidelink communication and an inter-UE cancellation indication that may be associated with a second communication, a priority between the first sidelink communication and an intra-UE channel prioritization for uplink communication with a base station over two or more channels, and any combination thereof. In some examples of the methods, apparatus, and non-transitory computer-readable media described herein, receiving the first indication may include an operation, feature, component, or instruction for receiving an uplink cancellation indication (UL CI) from the base station indicating a second set of resources, and wherein the UL CI may be associated with the second priority and indicate that one or more UEs different from the first UE will transmit using the second set of resources.

[0012] In some examples of the methods, apparatuses, and non-transitory computer-readable media described herein, the determination may include an operation, feature, component, or instruction for determining to stop the first side link communication based on a second priority level that is higher than the first priority level. In some examples of the methods, apparatuses, and non-transitory computer-readable media described herein, the determination may include an operation, feature, component, or instruction for determining to send the first side link communication based on a second priority level that is lower than the first priority level. In some examples of the methods, apparatuses, and non-transitory computer-readable media described herein, the second priority level may be assigned the same priority level as one or more uplink communications between the first UE and the base station. In some examples of the methods, apparatuses, and non-transitory computer-readable media described herein, the first priority level may be assigned a higher priority level than the second priority level, and the first side link communication may always have a priority level relative to the UL CI.

[0013] In some examples of the methods, apparatuses, and non-transitory computer-readable media described herein, the prioritization scheme provides a priority between a first side link communication, an uplink cancellation indication (UL CI) from a base station indicating a second priority and a second set of resources, and a third communication between a first UE and a base station. In some examples of the methods, apparatuses, and non-transitory computer-readable media described herein, the determination may also include an operation, feature, component, or instruction for determining which of the third communication or the first side link communication has a higher priority before determining whether to comply with the UL CI. In some examples of the methods, apparatuses, and non-transitory computer-readable media described herein, the determination may also include an operation, feature, component, or instruction for determining whether the second priority associated with the UL CI is a higher priority than one or more of the first priority or the third priority before determining whether the first priority has a higher priority than the third priority.

[0014] In some examples of the methods, apparatuses, and non-transitory computer-readable media described herein, the prioritization scheme provides a priority between a first sidelink communication, a first uplink communication between a first UE and a base station having a first channel priority, and a second uplink communication between the first UE and a base station having a second channel priority, and wherein the third group of resources is associated with one or more of the first uplink communication or the second uplink communication. In some examples of the methods, apparatuses, and non-transitory computer-readable media described herein, the prioritization scheme also provides: performing a priority between the first sidelink communication and the first and second uplink communications before prioritizing between the first uplink communication and the second uplink communication.

[0015] In some examples of the methods, apparatuses, and non-transitory computer-readable media described herein, a highest priority of the first channel priority and the second channel priority is selected as the second priority. In some examples of the methods, apparatuses, and non-transitory computer-readable media described herein, when the second priority is higher than the first priority and the first sidelink communication is stopped, a priority ranking between the first uplink communication and the second uplink communication is determined.

[0016] In some examples of the methods, apparatuses, and non-transitory computer-readable media described herein, the prioritization scheme further provides: prioritizing the first side link communication and each of the first uplink communication and the second uplink communication, respectively. In some examples of the methods, apparatuses, and non-transitory computer-readable media described herein, the determination may also include operations, features, components, or instructions for performing the following operations: determining to stop the first side link communication based on the fact that both the first uplink communication and the second uplink communication have a higher priority than the first side link communication, and determining which of the first uplink communication or the second uplink communication to send based on the first channel priority and the second channel priority.

[0017] In some examples of the methods, apparatus, and non-transitory computer-readable media described herein, the determination may also include operations, features, components, or instructions for performing the following operations: determining that the priority of the first uplink communication is higher than the priority of the second uplink communication based on the first channel priority and the second channel priority; setting the second priority to correspond to the first channel priority; and determining which of the first side link communication or the first uplink communication to send based on the first priority and the second priority.

[0027] A wireless communication system may support access links and side links for communication between one or more communication devices. An access link may be referred to as a communication link between a user equipment (UE) and a base station. For example, an access link may support uplink signaling, downlink signaling, a connection process, etc., and may be referred to as a Uu link. A side link may be referred to as any communication link between similar wireless devices (e.g., a communication link between UEs, or a backhaul communication link between base stations), and may be referred to as a PC5 link. Note that although the various examples provided herein are discussed with respect to UE side link devices, such side link technology may be used for any type of wireless device using side link communication. For example, a side link may support device-to-device (D2D) communication, vehicle-to-everything (V2X) or vehicle-to-vehicle (V2V) communication, message relay, discovery signaling, beacon signaling, or other signals wirelessly sent from one wireless device to one or more other similar wireless devices (e.g., UEs).

[0028] In some examples, when resources associated with access link communications overlap with side link resources used for side link communications, a side link device such as a UE may perform inter-UE prioritization, intra-UE prioritization, or a combination thereof. In some cases, the UE may be configured with a prioritization scheme that may be used to prioritize side link communications and access link communications. In some cases, inter-UE prioritization may be used when the UE receives an uplink cancellation indication (CI) from a base station that indicates that at least a portion of the radio resources configured for side link communications will be used for high priority communications at the base station (e.g., for high priority communications with another UE). This inter-UE prioritization may be used at the UE to determine whether to cancel all or part of the side link communications using the resources indicated in the CI, or to send the side link communications regardless of the CI. In some cases, additionally or alternatively, the prioritization scheme may include intra-UE prioritization, which, in the event of resource overlap between access link communications and side link communications, may be used at the UE to determine which of one or more access link communications (e.g., communications conducted on one or more access link channels having different priorities), side link communications, or a combination thereof, to maintain or cancel.

[0029] Certain aspects of the subject matter described in this disclosure may be implemented to achieve one or more of the following potential advantages. The techniques employed by the described UE may provide benefits and enhancements to the operation of the UE. For example, the operations performed by the UE may provide improvements in reliability and efficiency for wireless operations. In some examples, the UE may support high reliability by effectively prioritizing and canceling one or more instances of sidelink communications when necessary. Thus, the described techniques may include features for improving reliability in communications, improving communication efficiency based on prioritization of communications, and in some examples, may facilitate high reliability and low latency operations to improve efficiency, among other benefits.

[0030] Aspects of the present disclosure are first described in the context of a wireless communication system. Aspects of the present disclosure are then illustrated and described by side link resources and access link resources and process flows associated with prioritization of side link communications. Aspects of the present disclosure are further illustrated and described by apparatus diagrams, system diagrams, and flow diagrams associated with techniques for prioritizing communications for side link communications.

[0031] Figure 1 An example of a wireless communication system 100 according to various aspects of the present disclosure is illustrated, the wireless communication system supporting a technique for prioritizing communications for sidelink communications. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a long term evolution (LTE) network, an advanced LTE (LTE-A) network, an LTE-A Pro network, or a new radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communications, ultra-reliable (e.g., mission-critical) communications, low-latency communications, communications with low-cost and low-complexity devices, or any combination thereof.

[0032] The base stations 105 may be dispersed throughout a geographic area to form the wireless communication system 100, and may be devices of different forms or with different capabilities. The base stations 105 and the UE 115 may communicate wirelessly via one or more communication links 125. Each base station 105 may provide a coverage area 110 over which the UE 115 and the base station 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area over which a base station 105 and a UE 115 may support signal communications according to one or more radio access technologies.

[0033] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary, mobile, or both at different times. The UEs 115 may be devices of different forms or capabilities. Figure 1 Some example UEs 115 are shown in FIG. 1. The UEs 115 described herein can communicate with various types of devices, such as other UEs 115, base stations 105, or network devices (e.g., core network nodes, relay devices, integrated access backhaul (IAB) nodes, or other network devices), such as Figure 1 shown.

[0034] The base stations 105 may communicate with the core network 130, or with each other, or with both at the same time. For example, the base stations 105 may be connected to the core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3 or other interfaces). The base stations 105 may communicate with each other via the backhaul link 120 (e.g., via X2, Xn or other interfaces) directly (e.g., directly between base stations 105) or indirectly (e.g., via the core network 130) or both. In some examples, the backhaul link 120 may be or include one or more wireless links.

[0035] One or more of the base stations 105 described herein may include or may be referred to by a person of ordinary skill in the art as a base transceiver station, a radio base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB), a next generation NodeB or a giga-NodeB (both may be referred to as gNBs), a Home NodeB, a Home eNodeB, or other suitable terminology.

[0036] In other examples, UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device or a subscriber device, or some other suitable terminology, where "device" may also be referred to as a unit, a station, a terminal or a client. UE 115 may also include or may be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer or a personal computer. In some examples, UE 115 may include or may be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, and in other examples, the UE 115 may be implemented in various objects such as appliances, or vehicles, and meters.

[0037] The UE 115 described herein can communicate with various types of devices, such as other UEs 115, which may sometimes act as relays, as well as base stations 105 and network devices, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc. Figure 1 shown.

[0038] The UE 115 and the base station 105 may wirelessly communicate with each other via one or more communication links 125 through one or more carriers. The term "carrier" may refer to a set of radio spectrum resources with a defined physical layer structure for supporting the communication link 125. For example, a carrier for the communication link 125 may include a portion of a radio spectrum band (e.g., a bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-APro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating carrier operations, user data, or other signaling. The wireless communication system 100 may use carrier aggregation or multi-carrier operation to support communications with the UE 115. Depending on the carrier aggregation configuration, the UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may be used with frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0039] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling that coordinates the operation of other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (UTRA) Absolute Radio Frequency Channel Number (EARFCN)) and may be located according to a channel raster for discovery by a UE 115. A carrier may operate in a standalone mode, where initial acquisition and connection may be performed by a UE 115 via the carrier, or a carrier may operate in a non-standalone mode, where a different carrier (e.g., the same or different radio access technology) is used to anchor the connection.

[0040] The communication link 125 shown in the wireless communication system 100 may include an uplink transmission from the UE 115 to the base station 105, or a downlink transmission from the base station 105 to the UE 115. A carrier may carry downlink or uplink communications (e.g., in FDD mode), or may be configured to carry both downlink and uplink communications (e.g., in TDD mode).

[0041] A carrier may be associated with a specific bandwidth of a radio spectrum, and in some examples, the carrier bandwidth may be referred to as a "system bandwidth" of a carrier or wireless communication system 100. For example, a carrier bandwidth may be one of a plurality of determined bandwidths of a carrier for a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)). A device of the wireless communication system 100 (e.g., the base station 105, the UE 115, or both) may have a hardware configuration that supports communication on a specific carrier bandwidth, or may be configured to support communication on one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or a UE 115 that supports simultaneous communication via carriers associated with a plurality of carrier bandwidths. In some examples, each served UE 115 may be configured to operate on a portion (e.g., a subband, a BWP) or all of a carrier bandwidth.

[0042] The signal waveform transmitted on the carrier may be composed of multiple subcarriers (e.g., using multicarrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, a resource element may include a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and the subcarrier spacing are inversely proportional. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Therefore, if the UE 115 receives more resource elements and the order of the modulation scheme is higher, the data rate of the UE 115 may be higher. Wireless communication resources may refer to a combination of radio spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers may further improve the data rate or data integrity of communications with the UE 115.

[0043] The time interval of the base station 105 or the UE 115 may be expressed as a multiple of a basic time unit. For example, the basic time unit may refer to T s =1 / (Δf max ·N f ) seconds sampling period, where Δf max can represent the maximum supported subcarrier spacing, and N f The maximum supported discrete Fourier transform (DFT) size may be represented. Time intervals of communication resources may be organized according to radio frames, each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0044] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may be divided into subframes (e.g., in the time domain), and each subframe may be further divided into multiple 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 multiple symbol periods (e.g., depending on the length of the cyclic prefix appended to each symbol period). In some wireless communication systems 100, the time slot may be further divided into multiple micro-time slots containing one or more symbols. In addition to the cyclic prefix, each symbol period may contain one or more (e.g., N f ) sampling period. The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0045] A subframe, a time slot, a mini-time slot, or a symbol may be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in a burst of a shortened TTI (sTTI)).

[0046] Physical channels may be multiplexed on a carrier according to various techniques. For example, physical control channels and physical data channels may be multiplexed on a downlink carrier using one or more of a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique. A control region (e.g., a control resource set (CORESET)) of a physical control channel may be defined by a plurality of symbol periods and may extend across a subset of a system bandwidth or a system bandwidth of a carrier. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, one or more UEs 115 may monitor or search for a control region for control information according to one or more search space sets, and each search space set may include one or more control channel candidates of one or more aggregation levels arranged in a cascaded manner. The aggregation level of a control channel candidate may refer to a plurality of control channel resources (e.g., a control channel element (CCE)) associated with coded information of a control information format having a given payload size. A search space set may include a common search space set configured to transmit control information to a plurality of UEs 115, and a UE-specific search space set for transmitting control information to a particular UE 115.

[0047] Each base station 105 may provide communication coverage via one or more cells, such as macro cells, small cells, hot spots or other types of cells, or any combination thereof. The term "cell" may refer to a logical communication entity used to communicate with a base station 105 (e.g., via a carrier), and may be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or other) used to distinguish adjacent cells. In some examples, a cell may also refer to a geographic coverage area 110 or a portion of a geographic coverage area 110 (e.g., a sector) on which a logical communication entity operates. Depending on various factors such as the capabilities of the base station 105, such cells may range from smaller areas (e.g., structures, subsets of structures) to larger areas. For example, a cell may be or include a building, a subset of a building, an external space between or overlapping a geographic coverage area 110, and the like.

[0048] A macro cell typically covers a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access to a UE 115 with a service subscription to a network provider that supports the macro cell. A small cell may be associated with a base station 105 with lower power than a macro cell, and the small cell may operate in a frequency band that is the same or different (e.g., licensed, unlicensed, etc.) from the macro cell. A small cell may provide unrestricted access to a UE 115 with a service subscription to a network provider, or may provide restricted access to a UE 115 associated with a small cell (e.g., a UE 115 in a closed subscriber group (CSG), a UE 115 associated with a user in a home or office). A base station 105 may support one or more cells, and may also support communications on one or more cells using one or more component carriers.

[0049] In some examples, an operator may support multiple cells, and different cells may be configured based on different protocol types (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)) that may provide access to different types of devices.

[0050] In some examples, the base stations 105 may be mobile and thus provide communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but the different geographic coverage areas 110 may be supported by the same base station 105. In other examples, different base stations 105 may support overlapping geographic coverage areas 110 associated with different technologies. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of base stations 105 provide coverage for various geographic coverage areas 110 using the same or different radio access technologies.

[0051] Some UEs 115, such as MTC or IoT devices, may be low-cost or low-complexity devices and may provide automatic communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC may refer to data communication technology that allows devices to communicate with each other or with a base station 105 without human intervention. In some examples, M2M communication or MTC may include communications from a device that integrates sensors or meters to measure or capture information and forward such information to a central server or application that utilizes the information or presents the information to a human interacting with the application. Some UEs 115 may be designed to collect information or implement automatic behavior of a machine or other device. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based service charging.

[0052] Some UEs 115 may be configured to employ an operating mode that reduces power consumption, such as half-duplex communication (e.g., a mode that supports unidirectional communication via transmission or reception but not simultaneous transmission and reception). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power saving techniques for UE 115 include entering a power saving deep sleep mode when not engaged in active communications, operating over a limited bandwidth (e.g., according to narrowband communications), or a combination of these techniques. For example, some UEs 115 may be configured to operate using a narrowband protocol type that is associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs)) within a carrier, within a guard band of a carrier, or outside a carrier.

[0053] The wireless communication system 100 can be configured to support ultra-reliable communication or low-delay communication, or various combinations thereof. For example, the wireless communication system 100 can be configured to support ultra-reliable low-delay communication (URLLC) or mission-critical communication. UE 115 can be designed to support ultra-reliable, low-delay or critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private communication or group communication, and can be supported by one or more mission-critical services, such as mission-critical push-to-talk (MCPTT), mission-critical video (MCVideo) or mission-critical data (MCData). Support for mission-critical functions can include service prioritization, and mission-critical services can be used for public safety or general commercial applications. The terms ultra-reliable, low-delay, mission-critical and ultra-reliable low-delay can be used interchangeably in this article.

[0054] In some examples, UE 115 may also be able to communicate directly with other UE 115 in a side link or device-to-device (D2D) communication link 135 (e.g., using a point-to-point (P2P) or D2D protocol, or a PC5 protocol). One or more UEs 115 utilizing D2D communication may be within a geographic coverage area 110 of a base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of the base station 105 or otherwise unable to receive transmissions from the base station 105. In some examples, a group of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system, in which each UE 115 transmits to each other UE 115 in the group. In some examples, the base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UEs 115 without the involvement of the base station 105.

[0055] In some systems, the D2D communication link 135 can be an example of a communication channel between vehicles (e.g., UE 115), such as a sidelink communication channel. In some examples, vehicles can communicate using vehicle-to-everything (V2X) communications, vehicle-to-vehicle (V2V) communications, or some combination of these. Vehicles can signal information related to traffic conditions, signal scheduling, weather, safety, emergency situations, or any other information related to the V2X system. In some examples, vehicles in a V2X system can communicate with roadside infrastructure (such as roadside units) or with a network, or both, using vehicle-to-network (V2N) communications via one or more network nodes (e.g., base station 105).

[0056] The core network 130 may provide user authentication, access permission, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) for managing access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) for routing packets or interconnecting to an external network. The control plane entity may manage non-access stratum (NAS) functions of UE 115 served by a base station 105 associated with the core network 130, such as mobility, authentication, and bearer management. User IP packets may be transmitted via a user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to an IP service 150 of a network operator. The operator's IP service 150 may include access to the Internet, an intranet, an IP multimedia subsystem (IMS), or a packet-switched streaming service.

[0057] Some network devices, such as base stations 105, may include subcomponents such as access network entities 140, which may be examples of access node controllers (ANCs). Each access network entity 140 may communicate with UE 115 through one or more other access network transport entities 145, which may be referred to as radio heads, smart radio heads, or transmission / reception points (TRPs). Each access network transport entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio heads and ANCs), or merged into a single network device (e.g., base station 105).

[0058] The wireless communication system 100 may operate using one or more frequency bands typically in the range of 300 Hz (MHz) to 300 GHz. Typically, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately 1 decimeter to 1 meter long. UHF waves may be blocked or redirected by buildings and environmental features, but these waves can penetrate structures sufficiently for macro cells to provide services to UEs 115 located indoors. Transmissions using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 km) compared to transmissions using smaller frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0059] The wireless communication system 100 can utilize both licensed and unlicensed radio spectrum bands. For example, the wireless communication system 100 can use license assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in unlicensed bands such as the 5 GHz industrial, scientific and medical (ISM) band. When operating in an unlicensed radio spectrum band, devices such as base stations 105 and UEs 115 can use carrier sensing for conflict detection and avoidance. In some examples, operations in unlicensed bands can be based on a combination of carrier aggregation configurations and component carriers operating in licensed bands (e.g., LAA). Operations in unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, D2D transmissions, and the like.

[0060] The base station 105 or UE 115 may be equipped with multiple antennas, which may employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of the base station 105 or UE 115 may be located in one or more antenna arrays or antenna panels, which may support MIMO operations, or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located in an antenna assembly, such as an antenna tower. In some examples, the antennas or antenna arrays associated with the base station 105 may be located in different geographical locations. The base station 105 may have an antenna array with multiple rows and columns of antenna ports, so that the base station 105 may use the antenna ports to support beamforming for communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays, which may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals sent via the antenna ports.

[0061] Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a base station 105 or a UE 115) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining signals communicated via antenna elements of an antenna array so that some signals propagating in a particular direction relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals communicated via antenna elements may include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. Adjustments associated with each of the antenna elements may be defined by a set of beamforming weights associated with a particular direction (e.g., relative to the antenna array of the transmitting device or the receiving device, or relative to some other direction).

[0062] The wireless communication system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, the communication at the bearer or packet data convergence protocol (PDCP) layer may be IP-based. The radio link control (RLC) layer may perform packet segmentation and reassembly to communicate on a logical channel. The media access control (MAC) layer may perform priority processing and multiplex logical channels into transport channels. The MAC layer may also use error detection techniques, error correction techniques, or both to support retransmission at the MAC layer to improve link efficiency. In the control plane, the radio resource control (RRC) protocol layer may provide the establishment, configuration, and maintenance of an RRC connection between a UE 115 and a base station 105 or a core network 130 that supports a radio bearer of user plane data. At the physical layer, a transport channel may be mapped to a physical channel.

[0063] UE 115 and base station 105 can support retransmission of data to increase the likelihood of successfully receiving data. Hybrid automatic repeat request (HARQ) feedback is a technique that increases the likelihood of correctly receiving data through communication link 125. HARQ can 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 examples, a device can support HARQ feedback for the same time slot, wherein the device can provide HARQ feedback in a specific time slot for data received in the previous symbol in the time slot. In other cases, the device can provide HARQ feedback in a subsequent time slot or according to some other time intervals.

[0064] In some cases, sidelink communications may be enabled between devices in the wireless communication system 100, such as between two or more UEs 115, via a sidelink 135. In some cases, a prioritization scheme may provide inter-UE prioritization and intra-UE prioritization, which may be used to prioritize sidelink communications and one or more access link communications. In some cases, the UE 115 may receive an uplink CI from the base station 105 indicating that at least a portion of the radio resources configured for sidelink communications will be used for high priority communications at the base station (e.g., for high priority communications with another UE 115). The prioritization scheme may include inter-UE prioritization, which may be used at the UE to determine whether to cancel all or part of the sidelink communications using the resources indicated in the CI, or to send the sidelink communications regardless of the CI. In some cases, additionally or alternatively, in the case of resource overlap between the access link and the sidelink communications, the intra-UE prioritization may be used at the UE 115 to determine which of the one or more access link communications or sidelink communications to maintain or cancel.

[0065] Figure 2 An example of a wireless communication system 200 that supports techniques for prioritizing communications for sidelink communications according to aspects of the present disclosure is illustrated. In some examples, the wireless communication system 200 can implement aspects of the wireless communication system 100. The wireless communication system 200 can include a base station 105-a and a group of UEs 115 (e.g., UEs 115-a to UEs 115-c), which can be examples of base stations 105 and UEs 115, respectively, as described with reference to FIG. Figure 1 In some cases, the group of UEs 115 may communicate with each other via sidelink communications (eg, within a V2X system, a D2D system, etc.).

[0066] In accordance with some aspects, the group of UEs 115 may communicate sidelink communications 230 with each other (or with another group of UEs 115) via a sidelink 205, which may be referred to as a PC5 link (e.g., using a peer-to-peer (P2P) or D2D protocol, such as a PC5 interface). For example, a UE 115-a may monitor a resource pool for the sidelink 205 or indications of sidelink resources (e.g., resource reservations, control channel transmissions, etc.) from other UEs 115 in the group. Additionally or alternatively, a UE 115 may have data to send to one or more UEs 115 in the group and may use the sidelink 205 to send the data. In some examples, the group of UEs 115 may utilize a sidelink 205, which may be referred to as a Uu link or Uu interface, in addition to an access link 210 with a base station 105.

[0067] For example, one or more UEs 115 may be within a coverage area 110-a of a base station 105 (e.g., see Figure 1 110). In such an example, one or more UEs 115, including UE 115-a, may communicate with base station 105 via access link 210 (e.g., a Uu link for communications that may send downlink communications to one or more UEs 115 and carry uplink communications to base station 105-a). In some other examples, one or more UEs 115 may not be within coverage area 110-a, or may not communicate with base station 105 using an access link. In some cases, UE 115 may be configured with one or more resource pools for sidelink 205 that may carry sidelink communications 230. In some deployments, there may be two modes specified for sidelink communications 230 (e.g., in NR sidelink (PC5) communications), including mode 1 and mode 2, in which base station 105-a allocates sidelink resources among UEs 115, and in which UE 115 autonomously selects sidelink resources without control by base station 105-a. In Mode 1, the base station 105-a may provide a dynamic grant or activate a configured sidelink grant for the sidelink communication 230, and may report the sidelink feedback (e.g., HARQ ACK / NACK feedback) back to the base station 105-a by sending the sidelink feedback (e.g., HARQ ACK / NACK feedback) by the UE 115. In some cases, to enhance the reliability of high priority communications on the access link 210 or the side link 205, the UE 115 may be configured with a prioritization scheme for prioritizing one or more sidelink communications 230 relative to the resources of the access link 210.

[0068] In some cases, for example, base station 105-a may allocate resources for high priority traffic on access link 210 for UEs that use the latter (e.g., with Figure 2 15-a (which may be referred to as "later UEs"). Such resources may be allocated after a portion of all resources have been allocated for other communications, such as the first UE 115-a (which may be referred to as an "earlier UE"). To reduce the likelihood of interference in the allocated high priority resources, the base station 105-a may send a cancellation indicator 215. Such a cancellation indicator 215 may allow the base station 105-a to schedule a later UE with high priority traffic by signaling the earlier UE to cancel the lower priority traffic.

[0069] In some cases, a cancellation indicator 215 may be sent using a defined downlink control information (DCI) format (e.g., DCI format 2_4 in an NR system) that indicates that a set of resources (e.g., a first set of resources) is to be used for high priority traffic. For example, if UE 115-a detects a DCI format defined for a serving cell (e.g., DCI format 2_4), it may cancel the uplink transmission if one or more bits in the CI bitmap associated with the uplink resources overlap with resources allocated to UE 115-a (e.g., resources allocated for PUSCH transmission, repetitions of PUSCH transmissions, or SRS transmissions on access link 210). For example, if DCI format 2_4 includes symbols and PRBs of an earlier uplink communication of UE 115-a (e.g., if one or more T CI The value of the symbol has a bit value of "1" and one or more B CI In the case where cancellation indicator 215 indicates resources allocated for uplink transmission by UE 115-a, the cancellation may include all symbols from the earliest symbol of the uplink transmission that overlap with the set of resources signaled by cancellation indicator 215 that continues to the end of the uplink transmission. In the case where the uplink transmission is an SRS transmission, the cancelled symbols may only include symbols that overlap with the symbols indicated in cancellation indicator 215. According to various aspects of the present disclosure, as will be described with respect to Figure 3 As discussed in more detail, upon receiving the cancellation indicator 215 based on the prioritization scheme, the UE 115-a (or any other UE 115 configured for sidelink transmissions) may determine whether to cancel one or more sidelink communications 230.

[0070] In some cases, the prioritization scheme used at the UE 115 may also include prioritization of one or more of the communication channels on the access link 210 (e.g., which may provide higher priority uplink communications 220 and lower priority uplink communications 225), the sidelink communications 230, and the cancellation indicator 215. The prioritization between the higher priority uplink communications 220 and the lower priority uplink communications 225 relative to the sidelink communications 230 may be referred to as intra-UE prioritization. The higher priority uplink communications 220 and the lower priority uplink communications 225 may include uplink shared channel communications (e.g., PUSCH communications), uplink control channel communications (e.g., PUCCH communications), or any combination thereof.

[0071] In some cases, on the access link 210, the intra-UE prioritization may provide that when a higher priority uplink communication 220 overlaps at least a portion of a lower priority uplink communication 225, the UE 115-a anticipates cancelling all or a portion of the lower priority uplink communication 225. For example, the UE 115-a may be configured with resources for the lower priority uplink communication 225 and receive a scheduling PDCCH that schedules the overlapping higher priority uplink communication 220. In this case, starting from a defined symbol after the scheduling PDCCH (e.g., from T after the end of the scheduling PDCCH), the UE 115-a may be configured with resources for the lower priority uplink communication 225. proc,2 +d1 symbol starts, where T proc,2 d2 is a value corresponding to the processing time capability of the carrier at UE 115-a, and d1 is a duration corresponding to 0, 1, or 2 symbols reported by the UE capability. In some cases, under such conditions, the minimum processing time of the high priority channel associated with the higher priority uplink communication 220 can be extended by d2 symbols, where the value d2 is a duration corresponding to 0, 1, or 2 symbols reported by the UE capability. In addition, in the event that cancellation of the lower priority uplink communication 225 occurs due to overlap of the higher priority uplink communication 220 in the time slot, it is not desirable to schedule UE 115-a to transmit in the non-overlapping cancelled symbols.

[0072] In addition, where one or more sidelinks 205 are configured, the intra-UE prioritization may also take into account the relative priority of the sidelink communication 230 relative to one or more uplink transmissions, which may include one or both of a higher priority uplink communication 220 and a lower priority uplink communication 225. In some cases, the intra-UE prioritization may be used where the sidelink 205 is configured for mode 1 sidelink communication, where the base station 105-a allocates resources for the sidelink communication 230 between the UEs 115. Where the sidelink 205 is configured for mode 2 sidelink communication, the UE 115 may autonomously select the sidelink resources without the control of the base station 105, so that non-conflicting resources may be selected. In mode 1 communication, the base station 105-a may provide a dynamic grant or activate a configured sidelink grant for the sidelink communication 230, and the sidelink feedback may be reported back to the base station 105-a by the transmitting UE 115. In mode 1, the UE 115 may be scheduled to send an uplink transmission that overlaps with the transmission of the sidelink 205. In some cases, such a UE 115 may prioritize overlapping transmissions based on the configured priority of the access link 210 (e.g., the priority indicated in the RRC) and the priority of the side link 205, and determine whether to send on the access link 210 or the side link 205 based on the priority ranking. In addition, in the case where there may be multiple access link 210 channel communications and / or CI (e.g., cancellation indicators 215, higher priority uplink communications 220, lower priority uplink communications 225), the UE 115 may use a priority ranking scheme such as discussed herein to determine whether to stop or send Uu or PC5, such as reference Figure 4 The prioritization techniques are discussed in more detail.

[0073] Figure 3 An example of a cancellation indication and associated resources 300 according to aspects of the present disclosure is illustrated, wherein the cancellation indication and associated resources support a technique for prioritizing communications for sidelink communications. In some examples, the cancellation indication and associated resources 300 can implement aspects of the wireless communication system 100 or 200. In this example, a UE (such as, Figure 1 or Figure 2 The UE 115) can be configured with a first set of resources 305 for sidelink communications.

[0074] In some cases, the first set of resources 305 may be configured as part of a sidelink configuration in which two or more UEs communicate directly. In some cases, the first set of resources 305 may be provided by a serving base station (e.g., Figure 1or 2) configuration of the base station 105. In this example, the UE may receive a cancellation indicator 310 that may identify a second set of resources 315, which may include higher priority resources (e.g., URLLC resources for URLLC communications of different UEs) or lower priority resources (e.g., if the sidelink communication is a high priority communication). For example, the cancellation indicator 310 indicating the second set of resources 315 may be received before the configured cancellation timing 320 at the UE. Therefore, the second set of resources 315 may be associated with communications of different UEs, and inter-UE priority sorting may be used at the UE to determine whether to cancel all or part of the first set of resources 305. In some cases, the UE may cancel a portion of the sidelink communication using the first set of resources 305, which starts with a starting symbol corresponding to the first symbol indicated in the cancellation indicator 310 and continues for multiple canceled symbols 325 until the first set of resources 305 ends.

[0075] In some cases, the prioritization scheme used to determine whether to cancel or send a sidelink communication using the first set of resources 305 in the presence of the cancellation indicator 310 can be an inter-UE prioritization based on a configured priority associated with the cancellation indicator 310, and the associated priority of the transmission using the second set of resources 315. In this case, when the uplink cancellation indicator 310 has a higher priority than the sidelink communication that will use the first set of resources 305, the UE can obey the uplink cancellation indication and cancel all or a portion of the sidelink transmission. Similarly, when the uplink cancellation indicator 310 has a lower priority than the sidelink communication, the UE will ignore the uplink cancellation indicator 310 and continue the sidelink communication using the first set of resources 305. In some cases, the prioritization scheme can be configured as part of the sidelink configuration provided to the UE (e.g., provided in RRC signaling from the base station or other sidelink UE) when establishing a sidelink connection with other UEs. In some cases, the inter-UE prioritization provides that the cancellation indicator 310 is assigned the same priority as the UE's uplink communication on the access link (e.g., assigned the same priority as the intra-UE prioritization of the access link communication). In other cases, the UE may always ignore the uplink cancellation indicator 310 and send the sidelink communication in the first set of resources 305 (e.g., setting the sidelink prioritization to a higher priority than any received cancellation indicator 310, such as when the sidelink communication provides, for example, critical safety information in a V2X system). This prioritization scheme can allow the UE and the base station to set appropriate priorities for different communications for different devices, which can enhance communication of higher priority data relative to lower priority data, thereby providing flexibility and efficiency in wireless communications. As discussed herein, the prioritization scheme at the UE may additionally or alternatively include intra-UE prioritization for one or more access link communications that may overlap with the sidelink communication, an example of which is shown in FIG. Figure 4 for discussion.

[0076] Figure 4 An example of multiple access link resources 400 according to aspects of the present disclosure is illustrated, wherein the multiple access link resources support a technique for prioritizing communications for sidelink communications. In some examples, the multiple access link resources 400 can implement aspects of the wireless communication system 100 or 200. In this example, a UE (such as, Figure 1 or Figure 2 The UE 115) can be configured with a first set of resources 405 for sidelink communication.

[0077] In some cases, the first set of resources 405 may be configured as part of a sidelink configuration in which two or more UEs communicate directly. In some cases, the first set of resources 405 may be provided by a serving base station (e.g., Figure 1 4 or 2) configuration of the base station 105. In this example, the UE may receive a first indication 410 that may identify an uplink grant or cancellation indication, and an associated second set of resources 415 for communications on the access link. In addition, the UE may receive a second indication 430 that may identify an uplink grant or cancellation indication, and an associated third set of resources 435 for communications on the access link. In some cases, the first indication 410 and the second indication 430 may be associated with different channels (e.g., URLLC and eMBB communication channels) that may have different priorities with respect to sidelink communications at the UE.

[0078] In some cases, one or more of the first indication 410 or the second indication 430 may provide a cancellation indicator. For example, the UE may be scheduled or configured to transmit on both the side link and the access link, and receive an uplink cancellation indicator (e.g., in the second indication 430). In addition, the UE may have overlapping resources between the side link resources and the access link resources. For example, the first indication 410 may provide an uplink grant for a second set of resources 415, which may overlap with the time and / or frequency resources of the first set of resources 405 for side link communication. In this example, the second indication 430 may provide a cancellation indication. In some cases, a prioritization scheme may provide that the side link communication has a lower priority than the access link communication associated with the second set of resources 415. Therefore, based on the first indication 410, the UE may determine to cancel a portion of the side link symbols 425 of the first set of resources starting from the first symbol 420 of the second set of resources 415. In the event that the side link communication has a higher priority, the UE may determine to stop the uplink communication via the second set of resources 415. In addition, in cases such as Figure 4 In some cases as shown in the example of , the second indication 430 may provide a cancellation indication that cancels at least a portion of the access link uplink transmission using the second set of resources 415. In addition, in this example, the third set of resources 435 indicated by the second indication 430 may have an initial symbol 440 start time that causes the third set of resources 435 to not overlap with the first set of resources 405. Based on the configured priority sorting scheme, the UE may determine to cancel one or more of the communications using the first set of resources 405 or the second set of resources 415.

[0079] In some cases, the prioritization scheme may provide for the UE to first determine the overlapping condition between the sidelink transmission and the access link transmission, regardless of any cancellation indication that may be received. Thus, in this case, the uplink cancellation indication provided in the second indication 430 may be honored after the access link prioritization and sidelink prioritization of communications using the first set of resources 405 and the second set of resources 415. Thus, in this example, if the prioritization scheme provides that the sidelink communication has a higher priority than the access link communication associated with the first indication 410, the UE may use the first set of resources 405 to send the sidelink communication and cease using the second set of resources 415 for uplink communication. In this case, the cancellation indication provided in the second indication 430 indicates a third set of resources 435 that does not overlap with the first set of resources 405, and thus the UE may ignore the cancellation indication provided in the second indication 430. In the event that the resources indicated by the cancellation indication do overlap with the first set of resources 405 and the UE has prioritized the sidelink communication over the access link communication, the UE may, for example, determine the cancellation indication provided in the second indication 430. Figure 3 In addition, in the case where the prioritization scheme prioritizes access link transmission over sidelink transmission, the UE may stop transmission of the canceled sidelink symbols 425 for the sidelink transmission and then determine whether to stop the portion of the second group of resources 415 that overlaps with the third group of resources 435 based on the access link inter-UE prioritization (e.g., by stopping symbols of the second group of resources 415 starting from the start time of the initial symbol 440 of the third group of resources 435).

[0080] In other cases, the prioritization scheme may provide that the UE applies an uplink cancellation indication on both the access link communication and the side link communication, and then prioritizes the access link communication and the side link communication. Figure 4 In the example of , the UE may therefore apply the cancellation indication of the second indication 430 to the sidelink transmission using the first set of resources 405 and the access link transmission using the second set of resources 415. In some cases, the prioritization scheme may provide that, because the access link communication using the second set of resources 415 is partially or completely canceled, the sidelink communication will be sent using the first set of resources 405 that does not conflict with the third set of resources 435. In other cases, the sidelink or access link communication may be selected based on a percentage of communications that will be canceled based on the cancellation indication, based on the priority of the communication channels associated with the access link and sidelink communications, based on which communication has an earlier start time, or any combination thereof.

[0081] In other cases, the first indication 410 may provide an uplink grant for a first channel (e.g., an eMBB channel), and the second indication 430 may provide an uplink grant for a second channel (e.g., a URLLC channel). Thus, the UE may be scheduled or configured to transmit on a side link and an access link, and may also be scheduled or configured to have transmissions with different priorities on the access link. In some cases, when the priority of the side link communication is lower than the priority of the access link communication, the UE may stop the side link transmission. However, after the access link priority is sorted within the UE, the UE may stop the low priority access link transmission and only retain the high priority transmission. In this case, in Figure 4 In the example of , the UE may therefore stop using the second set of resources 415 for access link transmission and reserve access link transmission using the third set of resources 435 so that the access link transmission and the side link transmission no longer overlap.

[0082] In some cases, a prioritization scheme may provide that the UE will prioritize between sidelink transmissions and access link transmissions before prioritizing access link transmissions within the UE. Such a prioritization scheme may provide that multiple access link transmissions are treated as a complete entity and then compared with the sidelink transmission. Whenever there is any overlap between the sidelink resources and the access link resources, prioritization between the access link and the sidelink is exercised, selecting the higher priority link for transmission and stopping the lower priority communication. In this case, if the access link communication has a higher priority, the UE may perform prioritization between multiple access link transmissions. In Figure 4 In the example of , the second set of resources 415 may be associated with eMBB communications having a lower priority than the sidelink communications, but the third set of resources 435 may be associated with URLLC communications having a higher priority than the sidelink communications, so the access link has a higher priority than the sidelink, and the sidelink communications (e.g., the entire sidelink transmission or a portion of the sidelink transmission corresponding to the canceled sidelink symbol 425) are stopped. The UE may then perform intra-UE access link prioritization to determine whether all or part of the access link communications using the second set of resources 415 and the third set of resources are sent or canceled.

[0083] In other cases, a prioritization scheme may provide for comparing multiple access link transmissions to side link transmissions based on the priority between the side link communication and the access link communication. If more than one access link transmission is selected, the UE may perform access link prioritization. Figure 4In the example of , the second group of resources 415 can be associated with eMBB communications having a lower priority than sidelink communications, but the third group of resources 435 can be associated with URLLC communications having a higher priority than sidelink communications, and thus, the prioritization scheme will provide for stopping eMBB communications on the access link and sending sidelink transmissions and URLLC transmissions because they are non-overlapping.

[0084] In other cases, a prioritization scheme may be provided where the UE first performs intra-UE access link transmission prioritization and then prioritizes sidelink transmissions. This prioritization may provide Figure 4 In an example of a second set of resources 415 associated with eMBB communications may be stopped in favor of higher priority URLLC communications in the third set of resources 435. Sidelink prioritization may then provide that the sidelink communications are sent using the non-overlapping first set of resources 405. In other examples where the third set of resources 435 will overlap with the first set of resources 405, the priority of the sidelink communications may be compared to the priority of the third set of resources 435, and the higher priority communications may be sent and the lower priority communications stopped.

[0085] Figure 5 An example of a process flow 500 according to various aspects of the present disclosure is illustrated, which supports a technique for prioritizing communications for sidelink communications. In some examples, the process flow 500 can implement various aspects of the wireless communication system 100 or 200. The process flow 500 can be implemented by a transmitting UE 115-d, a receiving UE 115-e, and a serving base station 105-b, which can be examples of UE 115 and base station 105 described herein. The following alternative examples can be implemented, in which some steps are performed in a different order than described or not performed at all. In some cases, the steps may include additional features not mentioned below, or more steps may be added.

[0086] At 505, the transmitting UE 115-d, the receiving UE 115-e, and the base station 105-b may establish a sidelink communication connection between the transmitting UE 115-d and the receiving UE 115-e. In some cases, the sidelink communication may be a unicast communication. In other cases, the sidelink communication may be a broadcast or multicast communication to multiple UEs 115.

[0087] At 510, in the case of a broadcast or multicast transmission, the transmitting UE 115-d may identify sidelink resources for one or more sidelink transmissions to the receiving UE 115-e and optionally one or more other receiving UEs. In some cases, the base station 105-b may configure the sidelink resources in accordance with mode 1 sidelink communications. In some cases, the sidelink resources may be configured resources (e.g., configured by RRC signaling), which may be activated or deactivated by the base station 105-b.

[0088] At 515, the transmitting UE 115-d may determine a priority ranking between the sidelink communications and the base station communications. In some cases, the priority ranking may be determined based on a priority ranking scheme configured at the transmitting UE 115-d. In some cases (e.g., in RRC signaling configuring the sidelink communications, in a media access control (MAC) control element, etc.), the priority ranking scheme may be configured or activated by the base station 105-b. As discussed herein, the priority ranking scheme may include inter-UE priority ranking of access link communications and sidelink communications, intra-UE priority ranking of access link communications and sidelink communications, or any combination thereof.

[0089] Optionally, at 520, the base station 105-b may determine that a cancellation indicator is to be sent. In some cases, such a determination may be made based on the base station 105-b identifying a high priority communication to be sent instead of one or more lower priority communications. In some cases, the base station 105-b may determine resources associated with the high priority communication and configure a set of bits to be sent with the cancellation indicator to indicate one or more symbols, PRBs, or a combination thereof, which include the high priority communication. At 525, the base station 105-b may send an uplink cancellation indicator to the transmitting UE 115-d.

[0090] At 530, the transmitting UE 105-d may receive the cancellation indicator and determine to cancel or send the sidelink communication based on the cancellation indicator and the prioritization scheme. In some cases, the transmitting UE 105-d may determine that the resources provided by the cancellation indicator overlap with the sidelink communication resources and initiate the prioritization scheme based on the overlapping resources. Based on the prioritization scheme, the transmitting UE 115-d may cancel or send the sidelink transmission. In the event that the sidelink communication takes precedence over the cancellation indication, the transmitting UE 115-d may send the sidelink transmission at 535. In the event that the cancellation indication takes precedence over the sidelink communication, the transmitting UE 115-d may cancel the sidelink transmission.

[0091] At 540, the base station 105-b may determine one or more uplink grants for uplink communications on an access link between the transmitting UE 115-d and the base station 105-b. In some cases, the base station 105-b may provide two or more uplink grants for two or more different types of communications on the access link (e.g., UL RRC communications, eMBB communications, etc.). At 545, the base station 105-b may send the uplink grant(s) to the transmitting UE 115-d.

[0092] At 550, the transmitting UE 115-d may receive uplink grant(s) and determine to send or cancel uplink communications and sidelink communications based on the prioritization scheme and the uplink grant(s). In some cases, the prioritization scheme may provide that prioritization of uplink communications on the access link is first performed using the base station 105-b, and then the resulting priority is used for prioritization between access link communications and sidelink communications. In other cases, the prioritization scheme may provide that each uplink grant is prioritized separately relative to the sidelink transmission, and in the event that multiple access link transmissions remain after prioritization relative to the sidelink, the access link transmissions may be prioritized according to the intra-UE access link prioritization.

[0093] Based on the prioritization scheme indicating that the sidelink communication is to be sent, the transmitting UE 115-d may send the sidelink communication to the receiving UE 115-e at 555. At 560, based on the prioritization scheme indicating that one or more access link communications are to be sent, the transmitting UE 115-d may send the access link communication(s) to the base station 105-b. At 565, the receiving UE 115-e may decode any sidelink communication sent by the transmitting UE 115-d. Likewise, at 570, the base station 105-b may decode any sidelink communication sent by the transmitting UE 115-d.

[0108] Figure 8 A block diagram 800 of a communication manager 805 is shown that supports techniques for prioritizing communications for sidelink communications in accordance with aspects of the present disclosure. The communication manager 805 may be an example of aspects of the communication manager 615, the communication manager 715, or the communication manager 910 as described herein. The communication manager 805 may include a sidelink resource manager 810, an uplink resource manager 815, a prioritization manager 820, a cancellation indication manager 825, and an uplink channel manager 830. Each of these modules may communicate with each other directly or indirectly (e.g., via one or more buses).

[0109] The sidelink resource manager 810 may identify a first set of resources for a first sidelink communication using a second UE, wherein the first sidelink communication has a first priority.

[0110] The uplink resource manager 815 may receive a first indication of a second set of resources for a second communication, the second communication having a second priority, wherein the second set of resources at least partially overlaps with the first set of resources. In some examples, the uplink resource manager 815 may receive a second indication of a third set of resources for a third communication, the third communication having a third priority.

[0111] The prioritization manager 820 may determine to stop or send the first side link communication based on a prioritization scheme associated with the first priority, the second priority, and the third priority. In some examples, the prioritization manager 820 may determine to stop the first side link communication based on a second priority having a higher priority than the first priority. In some examples, the prioritization manager 820 may determine to send the first side link communication based on a second priority having a lower priority than the first priority. In some examples, the prioritization manager 820 may determine which of the third communication or the first side link communication has a higher priority before determining whether to honor the uplink cancellation indication.

[0112] In some examples, the prioritization manager 820 may determine to stop the first side link communication based on both the first uplink communication and the second uplink communication having a priority higher than the priority of the first side link communication. In some examples, the prioritization manager 820 may determine which of the first uplink communication or the second uplink communication to send based on the corresponding first channel priority and the second channel priority. In some examples, the prioritization manager 820 may determine that the first uplink communication has priority over the second uplink communication based on the first channel priority and the second channel priority. In some examples, the prioritization manager 820 may set the second priority to correspond to the first channel priority.

[0113] In some examples, the prioritization manager 820 can determine which of the first side link communication or the first uplink communication to send based on the first priority and the second priority. In some cases, the prioritization scheme provides a priority between the first side link communication and an inter-UE cancellation indication associated with the second communication, a priority between the first side link communication and an intra-UE channel prioritization for uplink communication with a base station via two or more channels, and any combination thereof. In some cases, the second priority is assigned the same priority as one or more uplink communications between the first UE and the base station.

[0114] In some cases, the prioritization scheme provides a priority between a first side link communication, an uplink cancellation indication (UL CI) from the base station indicating a second priority and a second set of resources, and a third communication between the first UE and the base station. In some cases, the first priority is assigned a higher priority than the second priority, and the first side link communication always has priority over the uplink cancellation indication.

[0115] In some cases, the prioritization scheme further provides for separately prioritizing the first sidelink communication and each of the first uplink communication and the second uplink communication.

[0116] The cancellation indication manager 825 may receive an uplink cancellation indication (ULCI) indicating a second set of resources from a base station, and wherein the UL CI is associated with a second priority and indicates that one or more UEs different from the first UE will use the second set of resources for transmission. In some examples, the cancellation indication manager 825 may determine whether the second priority associated with the UL CI is a priority higher than one or more of the first priority or the third priority before determining whether the first priority has a priority higher than the third priority.

[0117] The uplink channel manager 830 can manage the priorities of two or more different uplink channels. In some cases, the priority sorting scheme provides a priority between a first side link communication, a first uplink communication between a first UE and a base station with a first channel priority, and a second uplink communication between a first UE and a base station with a second channel priority, and wherein a third group of resources is associated with one or more of the first uplink communication or the second uplink communication. In some cases, the priority sorting scheme also provides: performing a priority sorting between the first side link communication and the first and second uplink communications before the priority sorting between the first uplink communication and the second uplink communication. In some cases, the highest priority of the first channel priority and the second channel priority is selected as the second priority. In some cases, when the second priority is higher than the first priority and the first side link communication is stopped, the priority sorting between the first uplink communication and the second uplink communication is determined.

[0121] The I / O controller 915 can manage the input and output signals of the device 905. The I / O controller 915 can also manage peripheral devices that are not integrated into the device 905.

The code 935 may be stored in a non-transitory computer-readable medium, such as a system memory or other type of memory.
