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: Aspects of the present disclosure provide techniques for configuring device-to-device (D2D) communication in new radio (NR) for one or more user equipments (UEs). Specifically, features of the present disclosure provide techniques for initial beam-pairing for sidelink communication that optimize communication resources (e.g., resource pools) by indicating the direction of traffic (e.g., transmit or receive) during the initial beam-pairing procedure and to establish sidelink communication without the need for scheduling request transmissions between the UEs.

Abstract: Some aspects provide a method for wireless communication by a first wireless device. The method generally includes transmitting control information regarding at least one of scheduling or configuration of a channel state information (CSI) report to be transmitted by the first wireless device. The method generally includes generating the CSI report based on one or more CSI reference signals (CSI-RSs) received by the first wireless device. The method generally includes and transmitting the CSI report in accordance with the control information.

Abstract: Certain aspects of the present disclosure provide techniques for managing a hybrid automatic repeat request (HARQ) buffer. An example method that may be performed by a first user equipment (UE) includes dropping, in response to a HARQ budget that is exceeded relative to a number of active HARQ processes, according to one or more rules, at least one of the transmissions or one or more transport blocks (TBs) associated with the at least one of the transmissions from being processed. The method further includes processing the remaining transmissions and taking one or more actions based on the processed remaining transmissions.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a source UE, a first sidelink communication. The UE may generate a transmit power control command based at least in part on a signal to interference noise ratio measurement associated with the first sidelink communication. The UE may transmit, to control a transmit power for a second sidelink communication, the transmit power control command to the source UE. 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 receive a transmit power control (TPC) command that is based at least in part on a scheduled transmission of a sidelink communication. The UE may determine, based at least in part on refraining from transmitting the sidelink communication or transmitting the sidelink communication at a power that is lower than a power configured for the scheduled transmission of the sidelink communication, whether to adjust a transmit power of the UE based at least in part on the TPC command. The UE may selectively adjust the transmit power of the UE based at least in part on determining whether to adjust the transmit power. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for priority-based transmit power control. A method that may be performed by a user equipment (UE) includes communicating with at least a second UE via a link, determining a transmission power for transmitting information via the link based, at least in part, on a priority corresponding to the information, and outputting the information for transmission via the link in accordance with the determined transmission power.
