Abstract: A method for sidelink communication is provided. The method is applied to a peer-receiving UE (peer-Rx UE) in a sidelink communication. The method includes the steps of decoding a first sidelink control information (SCI) in a first time slot from a peer-transmitting UE (peer-Tx UE) successfully, wherein the first SCI provides a resource allocation information that indicates one or more time slots allocated for one or more second SCIs to be transmitted by the peer-Tx UE; performing SCI decoding in the one or more time slots allocated for the one or more second SCIs; and transmitting assistance information when a trigger condition is met, wherein the trigger condition is based on the performing SCI decoding in the one or more time slots allocated for the one or more second SCIs.

Abstract: A method for performing sidelink transmission over an unlicensed band is provided. The method includes performing a first-type listen-before-talk (LBT) process on the unlicensed band to obtain a channel occupancy time (COT) for the sidelink transmission. The first-type LBT process includes a random backoff process. Duration of the random backoff process is determined by a randomly generated LBT counter. The method further includes determining, based on a result from a sensing operation performed on the unlicensed band within a sensing window, a plurality of candidate sidelink resources on the unlicensed band within a sidelink resource selection window. The method also includes selecting, based on a completion time point of the first-type LBT process, a sidelink resource from the plurality of candidate sidelink resources. The method also includes performing the sidelink transmission within the obtained COT on the selected sidelink resource.

Abstract: A receive (Rx) UE performs blind detection to decode a first-stage Sidelink Control Information (SCI) in a received signal. The first-stage SCI contains control information for the Rx UE to locate time-and-frequency resources used by a transmit (Tx) UE. The time-and-frequency resources are used to transmit the first-stage SCI and a second-stage SCI via a Physical Sidelink Control Channel (PSCCH) and to transmit data via a Physical Sidelink Shared Channel (PSSCH) associated with the PSCCH. The Rx UE locates the second-stage SCI in the time-and-frequency resources based on the first-stage SCI. The second-stage SCI contains additional control information from the Tx UE to the Rx UE for the sidelink V2X communication. The Rx UE decodes the second-stage SCI using at least in part an identifier which identifies the Rx UE as a destination of the received signal.

Abstract: Aspects of the disclosure provide a method for physical broad-cast channel (PBCH) processing at a base station (B S) in a wireless communication system. The method can include performing a channel coding process to generate encoded PBCH data at the BS. The encoded PBCH data is to be carried in a synchronization signal block (SS block) having an SS block index (SBI), and transmitted from a cell having a cell ID. The method can further include performing a second scrambling over the encoded PBCH data with a second scrambling code determined based on the cell ID and the SBI to generate second scrambled PBCH data.

Abstract: Aspects of the disclosure provide an apparatus that includes a transceiver circuit and a baseband processing circuit. The transceiver circuit is configured to transmit signals that carry a data unit to another apparatus and receive signals that carry a response from the other apparatus. The baseband processing circuit is configured to provide a first digital stream to carry a data unit to the transceiver circuit for transmission, and provide a second digital stream to carry a portion of the data unit to the transceiver circuit for retransmission when the transceiver circuit receives a response that is indicative of a partial receiving failure of the data unit at the other apparatus.
