摘要： A wireless device receives one or more messages comprising spatial relation configuration parameters of a physical uplink control channel. The configuration parameters indicate a plurality of reference signal (RS) sets. An RS set of the plurality of RS sets comprises one or more RSs. A medium access control control element, activating the RS set of the plurality of RS sets, is received. A downlink control information, indicating an RS of the RS set, is received. A spatial domain transmission filter, for the physical uplink control channel, is determined based on based on the RS. Uplink control information is transmitted, via the physical uplink control channel, based on the spatial domain transmission filter.

摘要： A wireless device receives one or more radio resource control messages from a base station. The one or more radio resource control messages comprising configuration parameters of a cell for beam failure recovery. The configuration parameters indicate: a serving beam set, a plurality of candidate beam sets, and a monitoring priority of the plurality of candidate beam sets. A beam failure instance of the serving beam set is detected. In response to the detection, a first candidate beam set of the plurality of candidate beam sets is determined based on the monitoring priority. A candidate beam is selected from the first candidate beam set. A preamble associated with the candidate beam for the beam failure recovery is transmitted.

摘要： A wireless device receives a DCI from a base station. The DCI comprises a power control command of an uplink shared channel, a CSI request field, a hybrid automatic repeat request process number, and a redundancy version. Validation of the DCI for an activation of a semi-persistent CSI reporting is performed based on: a radio network temporary identifier of the semi-persistent CSI reporting, the hybrid automatic repeat request process number being set to a first value, and the redundancy version being set to a second value. The semi-persistent CSI reporting indicated by the CSI request field is activated in response to the validation being achieved. A semi-persistent CSI report is transmitted, based on the activated semi-persistent CSI reporting, via the uplink shared channel with a transmission power determined based on the power control command.

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： A wireless device receives configuration parameters comprising first parameters of downlink RSs and second parameter indicating that a default beam is used for uplink transmission. A DCI indicating a first uplink transmission via a PUSCH resource is received. A spatial relation information, for the first uplink transmission, is determined to be associated with one of the downlink reference signals in response to the second parameter indicating that the default beam is used. A transport block is transmitted via the PUSCH resource according to the spatial relation information.

摘要： A wireless device activates a first downlink bandwidth part (BWP) of a cell and a first uplink BWP of the cell. An active downlink BWP, identified with a second downlink BWP index, is switched from the first downlink BWP to a second downlink BWP. It is determined that the second downlink BWP is configured with one or more beam failure recovery (BFR) parameters. An active uplink BWP, identified with a second uplink BWP index that is the same as the second downlink BWP index, is switched, based on the determining, from the first uplink BWP to a second uplink BWP. The active downlink BWP is switched from the second downlink BWP to a third downlink BWP. Based on a determination that the third downlink BWP is not configured with one or more BFR parameters, the second uplink BWP is kept as the active uplink BWP.

摘要： A wireless device receives one or more configuration parameters for uplink bandwidth parts (BWPs) of a cell. A first preamble, for a random-access procedure, is transmitted via a first uplink BWP of the uplink BWPs. A random-access response comprising a backoff indicator is received. A backoff window associated with the backoff indicator is started. A second uplink BWP of the uplink BWPs, that is different from the first uplink BWP, is selected for transmission of a second preamble during the backoff window. The wireless device transmits, via the second uplink BWP and based on the selecting, the second preamble for the random-access procedure.

摘要： A wireless device receives one or more messages comprising configuration parameters. The configuration parameters indicate pathloss reference signals (RSs) for PUSCH pathloss estimation for transmissions via first and second panels. A medium access control control element (MAC CE) is received. The MAC CE indicates first pathloss RSs of the plurality of pathloss RSs for the first panel. The MAC CE indicates second pathloss RSs of the plurality of pathloss RSs for the second panel. A downlink control information (DCI) is received. The DCI indicates a first pathloss RS. The DCI indicates a second pathloss RS. The wireless device transmits, via the first panel, a first uplink transport block with a first uplink transmission power determined based on the first pathloss RS. The wireless device transmits, via the second panel, a second uplink transport block with a second uplink transmission power determined based on the second pathloss RS.

摘要： A wireless device receives message(s) comprising configuration parameter(s) indicating reference signal(s) of a cell. The configuration parameter(s) may indicate one or more preambles for a beam failure recovery procedure. The configuration parameter(s) may indicate a time alignment timer of a timing advance group comprising the cell. The time alignment timer may start in response to receiving a timing advance command for the timing advance group. The beam failure recovery procedure may be initiated in response to detecting a beam failure of the cell. The beam failure of the cell may be detected based on the reference signal(s) of the cell. A preamble of the one or more preambles may be transmitted for the beam failure recovery procedure. The beam failure recovery procedure may be aborted in response to an expiry of the time alignment timer during the beam failure recovery procedure.
