Abstract: A wireless device starts a beam failure recovery (BFR) timer in response to initiating a contention-free random access procedure for a BFR. Based on expiry of the BFR timer, a first preamble employing a contention-based random access for the BFR is transmitted. In response to not receiving a response for the first preamble, a preamble transmission counter is incremented from a value of the preamble transmission counter of the contention-free random access procedure before the expiry of the BFR timer. A second preamble is transmitted in response to a value of the preamble transmission counter being equal to or less than a number.

Abstract: A wireless device receives: a value for a discontinuous reception (DRX) inactivity timer; and a semi-persistent channel state information (SP-CSI) radio network temporary identifier (RNTI). receive a first downlink control information (DCI) corresponding to the SP-CSI RNTI is received. The SP-CSI RNTI indicates: activation of SP-CSI reporting; and no uplink grant for uplink packet transmission. The DRX inactivity timer is started based on the first DCI indicating the activation of the SP-CSI reporting. The DRX inactivity timer controls monitoring for DCIs of the SP-CSI RNTI. a transport block is transmitted based on receiving, while the DRX inactivity timer is running, a second DCI.

Abstract: A wireless device receives one or more messages comprising a parameter indicating a first value of a listen before talk (LBT) counter. The LBT counter is incremented based on an LBT procedure indicating an LBT failure for an uplink transmission via a first bandwidth part. Based on the LBT counter reaching the first value, a switch is made from the first bandwidth part to a second bandwidth part as an active bandwidth part.

Abstract: A wireless device receives configuration parameters indicating resource configurations of reference signals for a layer 1 reference signal received power (RSRP) reporting of a secondary cell. A control element indicating activation of the secondary cell is received. In response to the control element, a layer 1 RSRP report is transmitted. The layer 1 RSRP report comprises: a first field indicating a reference signal of the reference signals of the secondary cell; and a second field indicating a layer 1 RSRP value of the reference signal.

Abstract: A wireless device transmits one or more preambles in response to initiating a beam failure recovery. The wireless device determines a failure of the beam failure recovery based on a number of transmissions of the one or more preambles exceeding a first number. The wireless device determines a radio link failure in response to the failure of the beam failure recovery. The wireless device starts, based on the radio link failure, a radio resource control (RRC) connection re-establishment procedure with a radio link failure report indicating the failure of the beam failure recovery is a cause of the radio link failure.
