Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a second UE, a second synchronization signal at a reception time. The first UE may adjust a transmission time of a first synchronization signal, resulting in an adjusted transmission time, wherein the adjusted transmission time is based at least in part on the reception time of the second synchronization signal. The first UE may transmit the first synchronization signal at the adjusted transmission time. Numerous other aspects are described.

Abstract: Apparatus, methods, and computer-readable media for facilitating autonomous synchronization are disclosed herein. For example, a UE may be configured to perform an initial synchronization directly to PSCCH and PSSCH when other synchronization sources, such as GNSS, a base station, and/or SLSS, are unavailable. An example method for wireless communication at a user equipment includes receiving a PSCCH. The example method also includes performing an initial synchronization based on the PSCCH. In some examples, the method may also include receiving a PSSCH, and determining a logical subframe number modulo 10 based on the PSSCH. The logical subframe number modulo 10 may correspond to a sequence seed.

Abstract: Method and apparatus for SCI source and destination pruning. The apparatus generates CRC bits corresponding to a payload. The apparatus combines the CRC bits with source information and destination information associated with transmission of the payload to generate a modified CRC. The apparatus transmits, to a second UE, the modified CRC and the payload. The modified CRC may be generated based on an XOR operation between the CRC bits corresponding to the payload and the source information and the destination information. The apparatus may map to a payload one or more bits that correspond to source information and destination information associated with transmission of the payload. The apparatus may transmit, to a second UE, the payload comprising the one or more bits that correspond to the source information and the destination information mapped to the payload.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a control channel message encoded according to a first format that is associated with a different set of shared data channel parameters than a second format supported by the UE. The second format is a legacy format relative to the first format. The UE may further determine that the control channel message is encoded according to the first format based at least in part on comparing one or more bit values, of the control channel message, in bit positions corresponding to a set of bits defined by the second format, and one or more expected bit values defined by the first format. The UE may select one or more resources for transmission based at least in part on information included in the control channel message. Numerous other aspects are provided.
