Abstract: Methods, systems, and devices for wireless communications are described. A first UE may receive a message indicating a configuration or a sidelink discovery burst transmission window. The configuration may include time periods for transmitting multiple sidelink synchronization signals. The first UE may perform a channel access procedure during the sidelink discovery burst transmission window. The first UE may perform the channel access procedure for transmitting one or more of the sidelink synchronization signals according to a pattern indicated by the configuration. The pattern may be based on a quasi co-location relationship between associated pairs of the sidelink synchronization signals. The first UE may transmit the one or more sidelink synchronization signals to a second UE in accordance with the pattern indicated by the configuration.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for multi-bit feedback via a sidelink feedback channel. In some aspects, a first user equipment (UE) and a second UE may support a physical sidelink feedback channel (PSFCH) design that is capable of conveying multi-bit feedback across multiple resource blocks. For example, the first UE may monitor for one or more sidelink data messages from the second UE and may transmit, to the second UE over multiple resource blocks of a PSFCH, a feedback message indicating multiple feedback bits associated with the sidelink data messages. The first UE may indicate or otherwise convey the multiple feedback bits via various sequence types or coding schemes. Additionally, or alternatively, the first UE and the second UE may support a resource selection scheme involving one or more parameters associated with conveying multi-bit feedback over a PSFCH.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may monitor a set of physical sidelink shared channel (PSSCH) resources for sidelink messages from a second wireless device. The first wireless device may generate one or more codebooks that include acknowledgement (ACK) or negative acknowledgement (NACK) bits corresponding to the sidelink messages. The first wireless device may transmit one or more feedback messages to the second wireless device on one or more physical sidelink feedback channel (PSFCH) resources in accordance with a sidelink feedback configuration of the first wireless device. The one or more feedback messages may include an indication of the one or more codebooks. The techniques described herein may enable the first wireless device to transmit the one or more feedback messages to the second wireless device with higher throughput and greater signaling efficiency, among other benefits.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may receive an indication of a configuration for transmitting a propagation delay compensation (PDC) report and a reference signal resource for performing one or more round trip timing (RTT) measurements associated with the PDC report. The UE may receive control signaling from the base station which includes a request for the UE to transmit the PDC report which includes the one or more RTT measurements. The UE may transmit the PDC report based on receiving the request from the base station, and the UE may perform one or more PDC procedures based on transmitting the PDC report. In some other examples, the base station may transmit a request to a higher layer to obtain the RTT measurements, and may relay the RTT measurements to the UE for performing the PDC procedures.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE, a first channel occupancy time (COT) sharing request. The UE may transmit, to a third UE, after a time window has elapsed, a second COT sharing request, wherein the second COT sharing request is transmitted based at least in part on the first UE having received no response to the first COT sharing request within the time window or the first UE having received a negative response to the first COT sharing request within the time window. Numerous other aspects are described.

Abstract: Mechanisms for transmitting a plurality of uplink (UL) transmission block (TB) repetitions associated with a plurality of TBs in a configured grant (CG) resource are provided. In one aspect, a method for multi-TB PUSCH repetition performed by a CE includes determining, based on a first parameter and a second parameter, a number of transport blocks (TBS) for a multi-TB repetition uplink (UL) communication in a configured grant (CG) resource, where the first parameter indicates a first number of TB repetitions, and where the second parameter indicates a second number of TB repetitions. The method further includes transmitting, to a base station (BS) using the CG resource in an unlicensed band, a plurality of TB repetitions based on the determined number of TBs.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station using UE cooperation. For example, a first UE may transmit an uplink signal indicating a request for the base station to transmit a UE discovery request signal to a second UE. In response to transmitting the uplink signal, the first UE may receive a sidelink signal from the second UE. The sidelink signal may indicate that the second UE may be available for a cooperative link with the first UE. In some cases, based on the sidelink signal, the first UE may establish the cooperative link with the second UE. In some examples, based on establishing the cooperative link, the first UE may receive downlink communications from the base station via at least sidelink communications from the second UE over the cooperative link.
