Abstract: A user equipment (UE) determines that at least one resource of a first set of resources selected by the UE for sidelink communication overlaps with a second set of resources reserved by a set of UEs. The UE determines whether to reselect at least a subset of the first set of resources for a sidelink transmission upon determining that the at least one resource is an overlapping resource. The at least a subset of the first set of resources includes one of a first overlapping resource of the overlapping resource, the overlapping resource, or the overlapping resource and at least a subset of non-overlapping resources of the first set of resources.

Abstract: A method, a computer-readable medium, and an apparatus for wireless communication at a first user equipment (UE). A channel state information (CSI) report trigger can be received from a second UE, and a channel state information reference signal (CSI-RS) can be received from the second UE in a same slot as the CSI report trigger. A CSI report can be transmitted to the second UE based on the CSI-RS, the CSI report including information identifying the CSI-RS on which the CSI report is based. The UE that triggered the CSI report can determine the CSI-RS on which the CSI report is based using the information included in the CSI report.

Abstract: The present disclosure addresses selection of a modulation and coding scheme (MCS) for control information multiplexed on a data channel. A spectral efficiency associated with control information may be derived as a function of a spectral efficiency associated with data. A modulation order and/or code rate may be selected that is suitable for the spectral efficiency associated with the data. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be configured to determine a first MCS for control information based on spectral efficiency associated with transmission of data, and further configured to transmit the control information with the first MCS, the control information being multiplexed with data.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a first message identifying a set of UEs comprising one or more other UEs with which the UE is engaging in sidelink communication. The UE may transmit a second message, based at least in part on a determination of a loss of a sidelink connection to a previously-connected UE of the set of UEs, identifying a subset of the set of UEs and indicating the loss of the sidelink connection. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a second user equipment, an indication of a time buffer threshold associated with providing sidelink hybrid automatic repeat request feedback on a physical sidelink feedback channel. The UE may receive, from the second user equipment, an indication of an agreement to use the time buffer threshold. The UE may transmit, to the second user equipment and based at least in part on the indication of the agreement, sidelink hybrid automatic repeat request feedback for a sidelink communication received from the second user equipment, the sidelink hybrid automatic repeat request feedback being transmitted on the physical sidelink feedback channel based at least in part on the time buffer threshold. Numerous other aspects are provided.

Abstract: The present disclosure provides techniques for communicating feedback for data transmissions over a sidelink in a wireless communication system. For example, devices and methods are provided for wireless communication by a first wireless device. In one example, the first wireless device determines that only one of either feedback can be transmitted to a second wireless device or a second communication can be communicated, wherein the feedback is indicative of whether a data transmission is successfully decoded, and based on that prioritizes one of the feedback or the second communication. In another example, the first wireless device determines that only one of either feedback can be received from the second wireless device or a second communication can be communicated, wherein the feedback is indicative of whether the data transmission is successfully decoded by the second wireless device, and based on that prioritizes one of the feedback or the second communication.

Abstract: Apparatus, methods, and computer-readable media for facilitating beam-based sequence spaces for synchronization signals are disclosed herein. An example method for wireless communication for a first device includes selecting a subset of synchronization signal block (SSB) occasions including SSB occasions within an SSB period, and wherein the subset of SSB occasions is associated with a pairing of a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). The example method also includes transmitting an SSB using at least one SSB occasion from the subset of SSB occasions. An example method for wireless communication for a user equipment (UE) includes selecting a synchronization signal pairing associated with a pairing of a PSS and a SSS, wherein the synchronization signal pairing maps to a subset of SSB occasions including SSB occasions within an SSB period, and also includes monitoring for an SSB at each SSB occasion from the subset of SSB occasions.

Abstract: Aspects described herein relate to selecting a sidelink control information (SCI) format for indicating a minimum communication range parameter, where the SCI format is a common format defined for requesting both location-based feedback and signal strength-based feedback. SCI indicating a value for the minimum communication range parameter can be generated based on the SCI format. The SCI indicating the value for the minimum communication range parameter can be transmitted to one or more devices.

Abstract: Aspects of the present disclosure propose a mechanism whereby a nearby device may detect scenarios where one device is unable to receive communications from a transmitting device. For example, the nearby device may detect that concurrent transmissions of a transmitting device and intended recipient prevent reception by the intended recipient and provide feedback to the transmitting device. Rather than blindly retransmitting, the transmitting device may only retransmit when it receives feedback from the nearby device, saving power and avoiding unnecessary transmissions.

Abstract: Aspects of the present disclosure are directed to device-to-device (D2D) and, more particularly, vehicle-to-vehicle (V2V) communication in which an efficient ranging protocol allows efficient ranging-assisted vehicle positioning. A vehicle transmits a first slot ID in a first control period, to indicate a first time slot for transmitting a first ranging signal in a ranging cycle including a plurality of time slots. The vehicle transmits the first ranging signal in the first time slot in the ranging cycle. From a second vehicle, the first vehicle receives a second ranging signal in a second time slot that is different from the first time slot in the ranging cycle. The first vehicle determines a first time-of-arrival (ToA) of the second ranging signal when received by the first vehicle, and transmits the first ToA in a second control period.
