摘要： The present application relates to a method and an apparatus for sidelink burst transmission. The method includes: performing a channel access procedure for initiating a channel occupancy for sidelink transmission; transmitting sidelink control information (SCI) to another apparatus within the channel occupancy; wherein the SCI includes an indicator indicating a remaining duration of the channel occupancy; and transmitting sidelink data associated with the SCI to the another apparatus without exceeding the remaining duration of the channel occupancy.

摘要： Embodiments of the present disclosure relate to method and apparatus for HARQ feedback. According to an embodiment of the present disclosure, a method can include: transmitting, to a first user equipment (UE), location information of a second UE and a communication range required for at least one sidelink transmission from the second UE, wherein each of the at least one sidelink transmission comprises a set of transport blocks (TBs); detecting feedback information associated with a corresponding TB of the set of TBs from the first UE on a set of feedback resources; and determining whether to retransmit the corresponding TB of the set of TBs based on the detection result of the feedback information. Embodiments of the present disclosure can avoid unnecessary retransmission and can improve transmission efficiency in NR V2X groupcast communication.

摘要： Apparatuses, methods, and systems are disclosed for determining candidate synchronization signal block transmission resources. One method (800) includes receiving (802) first information indicating at least one candidate synchronization signal block transmission resource. The at least one candidate synchronization signal block transmission resource is useable for transmitting a synchronization signal block for inter-node discovery, measurement, or a combination thereof. The method (800) includes receiving (804) second information and downlink data corresponding to the second information. The method (800) includes decoding (806) the downlink data. Decoding the downlink data includes rate-matching around the at least one candidate synchronization signal block transmission resource.
