摘要： A wireless device receives one or more radio resource control messages. The one or more radio resource control messages indicating: a first control resource set (coreset) group; a second coreset group; a first physical uplink control channel (PUCCH) cell associated with a first index indicating the first coreset group; and a second PUCCH cell associated with a second index indicating the second coreset group. one or more transport blocks are received. A determination is made of a PUCCH cell for transmitting hybrid automatic repeat request (HARQ) feedback of the one or more transport blocks. The determining comprises: determining the first PUCCH cell in response to the one or more transport blocks being scheduled via the first coreset group; and determining the second PUCCH cell in response to the one or more transport blocks being scheduled via the second coreset group. The HARQ feedback is transmitted via the determined PUCCH cell.

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 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 one or more configuration parameters indicating: one or more reference signals for a beam failure detection procedure; and a discontinuous reception (DRX) configuration for controlling transitions between a DRX inactive state and a DRX active state. The beam failure detection procedure is performed based on measurements of the one or more reference signals. A first value of a counter is determined based on detecting at least one beam failure instance during the DRX active state. A transition from the DRX active state to the DRX inactive state is made based on the DRX configuration. The beam failure detection procedure is stopped in response to the transitioning. The beam failure detection procedure continues with the first value of the counter after transitioning from the DRX inactive state to the DRX active state.

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 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.
