摘要： A first wireless device, receives from a second wireless device, one or more configuration messages comprising a sidelink latency upper bound for sidelink channel state information (CSI) reporting. The first wireless device receives, during a first time slot, from the second wireless device a sidelink CSI reporting triggering indication and one or more CSI reference signals. The first wireless device determines one or more sidelink CSI reporting resources within a time period indicated by the sidelink latency upper bound and starting from the first time slot. The first wireless device transmits one or more sidelink CSIs on the one or more sidelink CSI reporting resources.

摘要： A wireless device receives one or more messages indicating transmission resource pools of a sidelink. The transmission resource pools comprise: a first transmission resource pool for a zone in which the wireless device is located and a second transmission resource pool. The wireless device is allowed to use the second transmission resource pool based on one or more thresholds associated with sidelink transport blocks. A determination is made that a transport block meets the one or more thresholds. A selection is made, based on the determination, of one or more sidelink resources from the first transmission resource pool and the second transmission resource pool. The transport block is transmitted via the one or more sidelink resources.

摘要： A wireless device receives one or more radio resource control (RRC) messages. The RRC messages comprise: one or more first feedback parameters for selecting first feedback radio resources of a sidelink; and one or more second feedback parameters for selecting second feedback radio resources of the sidelink. A sidelink transmission comprising sidelink control information (SCI) indicating a priority level of the sidelink transmission is received. Based on the priority level, one or more radio resources are selected from one of: the first feedback radio resources based on the one or more first feedback parameters; and the second feedback radio resources based on the one or more second feedback parameters. A hybrid automatic repeat request (HARQ) feedback for the sidelink transmission is transmitted via the selected one or more radio resources.

摘要： A wireless device receives one or more messages. The one or more messages indicate: a plurality of repetition values of a physical sidelink shared channel (PSSCH); and a repetition threshold for the PSSCH. A sidelink control information is received. The sidelink control information schedules a transport block. The sidelink control information indicates a first repetition value of the plurality of repetition values. The transport block is received via the PSSCH. A determination is made, based on the first repetition value and the repetition threshold, to transmit an acknowledgment for the transport block. The acknowledgment for the transport block is transmitted.

摘要： A wireless device receives a first configuration message comprising a cell specific time division duplex (TDD) uplink (UL)-downlink (DL) pattern indicating a number of uplink slots. A size of a sidelink resource pool bitmap based on the number of the uplink slots is determined. The wireless device receives, based on the size of the sidelink resource pool bitmap, a second configuration message comprising a sidelink resource pool bitmap. One or more sidelink slots are determined by applying the sidelink resource pool bitmap to the uplink slots. The wireless device transmits one or more transport blocks via the one or more sidelink slots.

摘要： A first wireless device measures a channel busy ratio (CBR). Sidelink control information is received from a second wireless device, via a physical sidelink control channel (PSCCH). The sidelink control information comprises: a number of demodulation reference signal (DMRS) antenna ports; and resource assignment of a physical shared channel (PSSCH) received in one or more first resources. A first reference signal received powers (RSRPs) for a first DMRS antenna port of the PSSCH is measured. A second RSRP of the PSSCH is determined based on: the first RSRP, the number of DMRS antenna ports, and the CBR. One or more second resources are selected, based on the second RSRP of the PSSCH, for transmission within a set of candidate resources. One or more transport blocks are transmitted via the one or more second resources.

摘要： A first wireless device receives, from a base station, one or more radio resource control messages indicating a type of demodulation reference signal (DMRS). The first wireless device determines a length of the DMRS. The first wireless device determines a DMRS configuration of a physical sidelink shared channel (PSSCH) based on based on the type and the length of the DMRS. The first wireless device transmits, to a second wireless device, sidelink control information comprising the DMRS configuration of the PSSCH.

摘要： A first wireless device receives, from a base station, a configuration message indicating: a first power control parameter set for a first sidelink feedback type; and a second power control parameter set for a second sidelink feedback type. The first wireless device receives, from a second wireless device, a sidelink feedback type indication one of the first sidelink feedback type and the second sidelink feedback type. The first wireless device selects, based on the sidelink feedback type indication, one of the first power control parameter set and the second power control parameter set as a selected power control parameter set. The first wireless device determines a transmit power of a feedback signal based on the selected power control parameter set. The first wireless device transmits to the second wireless device, the sidelink feedback signal based on the transmit power.

摘要： A wireless device may determine that sidelink data is transmitted in a slot via multi-layer transmission over multiple antenna ports. A mapping the same sidelink control information to each antenna port of the multiple antenna ports may be made. The sidelink control information based on the mapping and the sidelink data are transmitted during the slot.

摘要： A wireless device receives one or more RRC messages comprising configuration parameters of a cell. The configuration parameters indicate uplink BWPs of an uplink carrier of the cell. The uplink BWPs comprise a first uplink BWP and a second uplink BWP. The configuration parameters further indicate a sidelink BWP of the uplink carrier of the cell. A numerology of the second uplink BWP is different than a numerology of the sidelink BWP. The wireless device activates the first uplink BWP. The wireless device activates the sidelink BWP. The wireless device switches from the first uplink BWP to the second uplink BWP as an active uplink BWP. The wireless device deactivates, based on the switch, the sidelink BWP.
