    摘要: A wireless device receives one or more messages comprising configuration parameters indicating a timer value of a bandwidth part (BWP) inactivity timer. The BWP inactivity timer associated with the timer value is started in response to switching to a first BWP as an active BWP. A random-access procedure for a beam failure recovery is initiated based on reaching a number of beam failure instance indications for at least one downlink control channel of the first BWP. The BWP inactivity timer is stopped based on initiating the random-access procedure. The at least one downlink control channel is monitored for a control information addressed to the wireless device. The random-access procedure for the beam failure recovery is stopped in response to receiving the control information via the at least one downlink control channel. The BWP inactivity timer is restarted based on the stopping the random-access procedure.

    摘要: In an embodiment, a wireless device receives configuration parameters of a plurality of uplink (UL) transmission configuration indicator (TCI) codepoints. A first codepoint of the plurality of UL TCI codepoints indicates that an activated downlink (DL) TCI state is applicable for UL signal transmission. A second codepoint of the plurality of UL TCI codepoints indicates that a sounding reference signal resource indicator (SRI) is applicable for UL signal transmission. The wireless device receives a control command indicating a codepoint and determines a spatial domain filter based on the indicated codepoint being one of the plurality of UL TCI codepoints. The spatial domain filter is determined using: the activated DL TCI state based on the indicated codepoint being the first codepoint; and the SRI based on the indicated codepoint being the second codepoint. The wireless device transmits the UL signal using the determined spatial domain filter.

    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 may receive one or more messages comprise parameters of a first downlink control information (DCI) format and a second DCI format for monitoring on a first search space. The parameters may comprise the second DCI format configured for monitoring on a second search space. The wireless device may determine, based on the first DCI format, a first DCI size of the second DCI format for the first search space. The wireless device may determine, based on the second DCI format, a second DCI size of the second DCI format in the second search space. The wireless device may monitor for a first DCI on the first search space based on the first DCI size. The wireless device may monitor for a second DCI on the second search space based on the second DCI size.

    摘要: A wireless device transmits, one or more radio resource control (RRC) messages indicating assistance information for a sidelink operation. The assistance information indicates: an identifier indicating a logical channel associated with a sidelink traffic; and one or more periodicities associated with the logical channel. In response to the assistance information, one or more second RRC messages indicating one or more configured grant configurations determined based on the one or more of periodicities of the logical channel is received. The wireless device triggers, a transmission of a buffer status report in response to sidelink data of the logical channel becoming available. A scheduling request (SR) is transmitted. In response to the SR: the transmission of the buffer status report is cancelled; and one or more activation commands indicating activation of the one or more configured grant configurations is received.

    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 first message indicating a first transmission configuration indicator (TCI) state being applicable at a first time for receiving a downlink control channel. A second message is received and indicates a common TCI state being applicable at a second time for: receiving the downlink control channel; and receiving downlink data via a downlink shared channel. The wireless device determines that the second message is received after the first message and that the second time is earlier than the first time. Based on the determining, the downlink control channel is received based on the common TCI state and the downlink data is received via the downlink shared channel based on the common TCI state.
