Abstract: A method of two-stage sidelink control information (SCI) for sidelink transmission is described. In one novel aspect, the SCI is transmitted from a transmission UE (Tx UE) to a reception UE (Rx UE) in two stages. In one embodiment, the 1st-stage SCI carries information related to channel sensing, and is transmitted over a physical sidelink control channel (PSCCH). The 2nd-stage SCI is transmitted over a physical sidelink shared channel (PSSCH) associated with the PSCCH. In one embodiment, the first-stage SCI includes priority information or information of time-frequency resources for the SL transmission. In another embodiment, the first-stage SCI indicates time-frequency location of the second-stage SCI.

Abstract: A method of hybrid automatic repeat request (HARQ) feedback can include receiving data transmitted from a transmission (Tx) user equipment (UE) or a base station (BS) over a channel at a reception (Rx) UE, selecting an acknowledgement/negative acknowledgement (A/N) resource from a set of A/N resources for a HARQ feedback of the data based on a channel condition of the channel or a geographical location of the Rx UE, and transmitting the HARQ feedback with the selected A/N resource.

Abstract: A user equipment (UE) in wireless communication receives a configuration of search space (SS) sets that include a first SS set in a first control resource set (CORESET) and a second SS set in a second CORESET. The first CORESET and the second CORESET have different transmission configuration indication (TCI) states. The UE repeatedly receives downlink control information (DCI) via a first physical downlink control channel (PDCCH) and a second PDCCH. The first PDCCH is allocated with a first set of time-and-frequency resources configured for first SS set and the second PDCCH is allocated with a second set of time-and-frequency resources configured for the second SS set. The UE then parses the DCI to obtain control information for the wireless communication. Alternatively, the configuration of SS sets received by the UE is in one CORESET that has at least a TCI state and a second TCI state activated.

Abstract: A method of two-stage sidelink control information (SCI) can include receiving a transport block, and transmitting from a transmission user equipment (Tx UE) to a reception user equipment (Rx UE) the transport block with two-stage SCI including a 1st-stage SCI and a 2nd-stage SCI. The 1st-stage SCI can be transmitted over a physical sidelink control channel (PSCCH). The 2nd-stage SCI and the transport block can share resources of a physical sidelink shared channel (PSSCH). The 2nd-stage SCI and the transport block can share a demodulation reference signal (DMRS).

Abstract: User equipment (UE) for sounding reference signal (SRS) triggering is provided. The UE may include a radio frequency (RF) signal processing device and a processor. The RF signal processing device receives first slot offset information and second slot offset information from a network node. The first slot offset information is configured through a radio resource control (RRC) information element (IE) to indicate a first time difference between the down link control information (DCI) and a resource reference slot. The second slot offset information indicates the second time difference between the reference slot and an SRS resource. The processor is coupled to the RF signal processing device. When the RF signal processing device receives the DCI, the processor triggers an SRS transmission for the SRS resource according to the first slot offset information and the second slot offset information.
