摘要： A wireless device receives one or more messages. The one or more messages comprise configuration parameters of the cell. The configuration parameters indicate a plurality of control resource sets for multiple transmission reception points. Downlink control information (DCI) is received via a control resource set of the plurality of control resource sets. The DCI comprises a physical uplink control channel (PUCCH) resource indicator. The control resource set comprises one or more control channel elements starting from a first control channel element. A PUCCH resource is determined based on the PUCCH resource indicator. The PUCCH resource is determined based on an index of the first control channel element. The PUCCH resource is determined based on the control resource set. An uplink control information is transmitted via the PUCCH resource in response to the determination of the PUCCH resource.

摘要： A wireless device receives one or more messages. The one or more messages comprise configuration parameters of the cell. The configuration parameters indicate a first reference signal set for a first type of beam switching. The configuration parameters indicate a second reference signal set for a second type of beam switching. A beam switching type indication is transmitted. The beam switching type indication indicates one of the first type of beam switching or the second type of beam switching. A command confirming the beam switching type indication is received. One of the first reference signal set and the second reference signal set is selected as a selected reference signal set based on the command A spatial domain transmission filter is determined based on at least one reference signal of the selected reference signal set. An uplink transport block is transmitted based on the spatial domain transmission filter.

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.

摘要： A wireless device may receive one or more radio resource control (RRC) messages comprising first parameters of a first configured grant configuration of the cell and second parameters of a second configured grant configuration of the cell. The wireless device may trigger a power headroom report. The wireless device may determine one of: a first resource associated with the first configured grant configuration; and a second resource associated with the second configured grant configuration, as a selected uplink resource for transmitting the power headroom report. The wireless device may determine the selected uplink resource based on a first priority of the first configured grant configuration and a second priority of the second configured grant configuration. The first resource and the second resource may overlap in one or more symbols. The wireless device may transmit the power headroom report via the selected uplink resource.

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.

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.
