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.

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 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 initializes a candidate resource set. The candidate resource set comprises candidate resources in a selection window. The wireless device receives a second sidelink transmission. The second sidelink transmission comprises sidelink control information (SCI). The SCI indicates first resources during the selection window. The SCI indicates a priority of the second sidelink transmission. The priority is used for excluding the first resources from the candidate resource set. The wireless device excludes the first resources from the candidate resource set based on the priority being higher than a first priority threshold. The wireless device selects second resources from the candidate resource set based on the excluding of the first resources from the candidate resource set. The wireless device transmits a first sidelink transmission via the second resources.

摘要： A wireless device receives a sidelink (SL) downlink control information (DCI). The SL DCI indicates: one or more first frequency domain resources; one or more first time domain resources; and a periodicity. One or more SL control information (SCI) indicating the periodicity and one or more first SL transmissions is transmitted via a first set of SL resources. The first set of SL resources are determined based on the one or more first frequency domain resources and the one or more first time domain resources. One or more second SL transmissions are transmitted via a second set of SL resources determined based on: the one or more first frequency domain resources; the one or more first time domain resources; and the periodicity.

摘要： A wireless device receives, before a scheduled sidelink transmission via a resource of one or more resources of a sidelink resource pool of a cell, a downlink control information (DCI). The DCI indicates switching from a first bandwidth part of the cell to a second bandwidth part of the cell as an active bandwidth part. In response to the DCI: the second bandwidth part is activated after a delay from the reception of the DCI; the scheduled sidelink transmission via the resource of the one or more resources is dropped; and monitoring physical sidelink control channels for sidelink control information is skipped during the delay.

摘要： Described are embodiments for frequency selective transmission. In an embodiment, a wireless device receives a downlink control information indicating a transmission via uplink resources comprising sub-bands; and a sounding reference signal resource indicator (SRI). The wireless device selects, based on the SRI, one or more sounding reference signal (SRS) resources. Uplink precoders are determined for the transmission. The uplink precoders include an uplink precoder that is determined, for each respective sub-band of the sub-bands, based on a transmission precoder of the one or more SRS resources transmitted via the respective sub-band. The wireless device transmits, based on the determined uplink precoders, a transport block of the transmission via the uplink resources.

摘要： A wireless device triggers a first resource selection procedure for a sidelink transmission. A first ratio from ratios is determined for the first resource selection procedure. The first ratio indicates a first portion of first candidate radio resources. A second resource selection procedure for the sidelink transmission is triggered. A second ratio from the ratios is determined for the second resource selection procedure. The second ratio indicates a second portion of second candidate radio resources. Second remaining candidate radio resources are determined based on excluding third radio resource(s) from the second candidate radio resources. A RSRP of the third radio resource(s) is higher than a second RSRP threshold. Fourth radio resource(s) are selected from the second remaining candidate radio resources, based on a number of the second remaining candidate radio resources being more than the second portion of the second candidate radio 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.
