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 synchronization signal and physical broadcast channel (SS/PBCH) block. A control order for transmission of a preamble is received. A transmission power is determined for the preamble. The transmission power is based on: a received power value of a channel state information reference signal (CSI-RS) and a power offset value, in response to the wireless device configured with the CSI-RS; and a received power value of the SS/PBCH block and not based on the power offset value, in response to the wireless device not configured with CSI-RS. The preamble is transmitted based on the transmission power.

Abstract: A wireless device initiates a random access procedure for parallel transmissions of random access preambles for beams of a cell. A determination is made that a first calculated transmit power exceeds a first power value. The first calculated transmit power comprises transmission powers corresponding to the parallel transmissions of the random access preambles. In response to the determination, a first transmission of at least one first random access preamble of the random access preambles is dropped based on at least one first pathloss value corresponding to the first transmission being greater than at least one second pathloss value corresponding to a second transmission of at least one second random access preamble of the random access preambles. The at least one second random access preamble of the random access preambles is transmitted by the wireless device.

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 an indication for activation of packet data convergence protocol (PDCP) packet duplication of a radio bearer associated with a first radio link control (RLC) entity and a second RLC entity. A packet of the radio bearer is duplicated. The packet to the first RLC entity is provided. A duplicate packet to the second RLC is provided. The packet of the first RLC entity is transmitted. An acknowledgement of a successful delivery for the packet of the first RLC entity is received. In response to the acknowledgement, the duplicate packet of the second RLC entity is discarded.

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 RRC message(s) comprising: parameter(s) indicating whether a configured periodic grant of a first type can be used for transmission of data of a first logical channel; a timing offset and a symbol number identifying a resource of an uplink grant of the configured periodic grant of the type; and a first periodicity of the configured periodic grant. The first periodicity indicates a time interval between two subsequent resources of the configured periodic grant. The configured periodic grant is activated in response to receiving the RRC message(s). The data of the logical channel is multiplexed onto transport block(s) for transmission via the resource in response to the parameter(s) indicating that the configured periodic grant can be used by the logical channel. The transport block(s) are transmitted via the resource of the configured periodic grant.

Abstract: A wireless device receives, from a base station, at least one first message comprising a first periodicity of resources of a configured periodic grant of a first type. A request for transmission information associated with the configured periodic grant is received. A response is transmitted. The response comprises: a first value based on a number of transmissions via the resources the configured periodic grant; and a second value based on a number of times that the wireless device received no corresponding acknowledgement from the base station in response to the transmissions.
