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.

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 initiates a beam failure recovery procedure in response to detecting a first number of beam failure instances. A beam failure recovery timer is started with a first timer value. A first reference signal is selected in response to an expiry of the beam failure recovery timer. A first preamble associated with the first reference signal is transmitted. A downlink control channel for a downlink control information is monitored during a response window and in response to transmitting the first preamble. A preamble transmission counter is incremented, from a value of the preamble transmission counter before the expiry of the beam failure recovery timer, in response to not receiving the downlink control information during the response window. A second preamble for the beam failure recovery procedure is transmitted in response to the preamble transmission counter indicating a second number equal to or less than a third number for preamble transmissions.

摘要： A wireless device receives one or more messages comprising configuration parameters. The configuration parameters indicate: a plurality of bandwidth parts (BWPs) comprising a first BWP and a second BWP; and a timer value for a BWP inactivity timer. The BWP inactivity timer associated with the timer value starts in response to switching to the first BWP as an active BWP. A beam failure recovery procedure is initiated based on reaching a number of beam failure instance indications for the first BWP. Based on an expiry of the BWP inactivity timer during the beam failure recovery procedure: the beam failure recovery procedure for the first BWP is aborted; and the active BWP is switched from the first BWP to the second BWP.

摘要： A wireless device receives message(s) comprising configuration parameter(s) of a first cell and a second cell. The configuration parameter(s) indicate a plurality of bandwidth parts (BWPs) of the first cell. A first uplink BWP of the plurality of BWPs is activated as an active uplink BWP. A beam failure recovery procedure for the second cell is initiated based on detecting a beam failure. A determination that the first uplink BWP is not configured with one or more beam failure recovery resources for the second cell is made. The active uplink BWP of the first cell is switched, based on the determination, from the first uplink BWP to a second uplink BWP, of the plurality of BWPs, configured with the one or more beam failure recovery resources for the second cell. An uplink signal indicating the beam failure is transmitted via the second uplink BWP.

摘要： A wireless device receives one or more messages comprising one or more configuration parameters. The one or more configuration parameters indicate: a value of a timer for controlling a radio link failure indication based on a beam failure recovery procedure, and a first number of out-of-synchronization indications. The wireless device determines a second number of out-of-synchronization indications. The timer associated with the value is started in response to the second number being equal to the first number of out-of-synchronization indications. A first failure of the beam failure recovery procedure is determined. The first failure is ignored, by not causing a radio link failure, in response to the timer running when the first failure is determined. A second failure of the beam failure recovery procedure is determined. A radio link failure is indicated in response to the timer being expired when the second failure is determined.

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.
