Abstract: A method, a computer-readable medium, and an apparatus may be a first UE in a bundled TTI comprising a first TTI and a second TTI. The first UE is configured to receive a first data transmission and a first reference signal from a second UE in the first TTI, to transmit a SRS to the second UE, and to receive a second data transmission having one or more transmission parameters adapted based on the SRS in the second TTI. In certain aspects, the first UE is configured to transmit a first data transmission and a first reference signal to a second UE in the first TTI, to receive a SRS from the second UE, to adapt one or more transmission parameters for a second data transmission in the second TTI based on the SRS, and to transmit the second data transmission to the second UE in the second TTI.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, on a sidelink, a groupcast communication and a unicast communication concurrently from a transmitter. The UE may determine a feedback sequence to be transmitted to indicate joint acknowledgment or negative acknowledgement feedback for the groupcast communication and the unicast communication based at least in part on a decoding of the groupcast communication. The UE may transmit the feedback sequence in one or more sidelink feedback resources associated with a sidelink subchannel via which at least one of the groupcast communication or the unicast communication is received. Numerous other aspects are provided.

Abstract: Aspects directed towards network-assisted sidelink scheduling are disclosed. In one example, a scheduled entity receives coverage status information of a peer user equipment (UE), and transmits a coverage status report to a network in which the coverage status report is based on the coverage status information received from the peer UE. The scheduled entity receives a resource scheduling from the network in response to transmitting the coverage status report, and establishes a sidelink communication with the peer UE based on the resource scheduling. In another example, a scheduling entity receives a coverage status report from a UE in which the coverage status report is associated with a peer UE of the UE. The scheduling entity determines a resource scheduling for the UE based on the coverage status report to facilitate a sidelink communication between the UE and the peer UE, and transmits the resource scheduling to the UE.

Abstract: Aspects presented herein may enable vehicle UE(s) to transmit warning message(s) to one or more pedestrian UEs without receiving P2V transmissions from the one or more pedestrian UEs. In one aspect, a first UE determines one or more configuration parameters for a plurality of second UEs, the one or more configuration parameters including an identification parameter, the identification parameter being associated with a time period. The first UE determines, based on the identification parameter for at least one second UE of the plurality of second UEs, whether to transmit a warning message to the at least one second UE. The first UE transmits, based on determining to transmit the warning message, the warning message to the at least one second UE, the warning message including an ID for the at least one second UE, the ID for the at least one second UE being based on the identification parameter.

Abstract: Wireless communication systems and methods related to quality of service mapping, are provided. A first user equipment determines a sidelink radio bearer identifier (SLRB ID) for a quality of service (QoS) flow from a plurality of rules. The rules identify different characteristics of the QoS flow. The SLRB ID is inserted into a header of a packet in the QoS flow. The QoS flow is mapped to a radio bearer that is mapped to an L2 link with other radio bearers that are mapped to other QoS flows. The L2 link transmits the radio bearers to a second UE as part of a broadcast, groupcast or unicast sidelink communication. Based on the SLRB ID, the second UE identifies requirements of the QoS flow.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a plurality of hybrid automatic repeat request (HARQ) feedback for a plurality of sidelink communications. The UE may identify at least a subset of HARQ feedback from the plurality of HARQ feedback based at least in part on one or more parameters. The UE may transmit, on a sidelink, the at least the subset of HARQ feedback in a HARQ feedback occasion. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) that is configured to transmit a message to a neighboring UE via multiple formats, identify a service parameter indicative of a format to be used for the message. The UE may convey information indicating the service parameter from a first layer of the UE to a second layer of the UE, wherein the first layer is an upper layer with respect to the second layer. The UE may generate, by the second layer and based at least in part on the information, the message in the format for communicating with the neighboring UE. Other aspects, embodiments, and features are claimed and described.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may utilize priority levels associated with packets or transmissions to determine whether to transmit feedback for a received transmission. The UE may compare priority levels between a transmission subject to a feedback condition and a transmission scheduled to be received when the feedback is scheduled to be transmitted to determine whether to send the feedback. The UE may communicate with the transmitting device according to the comparison and the determining. The UE may determine signal conditions causing a NAK and determine to send the NAK based on the signal conditions.

Abstract: Techniques are provided for supporting sidelink communication between multiple user equipment (UEs), and which may be implemented in various apparatuses, methods, and/or articles of manufacture. In certain aspects a first UE may establish a sidelink schedule with a second UE, wherein the sidelink schedule corresponds to at least a subset of communication resources indicated available to both the first and second UEs by one or more corresponding link availability schedules or the like. The two UEs may then establish a sidelink with the second UE in accordance with the sidelink schedule. Multiple sidelink schedules may be agreed upon in certain instances such that the UEs may dynamically switch from one schedule to another as desired.
