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 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, 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.

Abstract: A wireless device receives one or more messages comprising: a parameter indicating that uplink duplication is configured for a bearer corresponding to a first logical channel and a second logical channel; first mapping restrictions of the first logical channel to at least one first cell; and second mapping restrictions of the second logical channel to at least one second cell. A control element indicating activation or deactivation of duplication for the bearer is received. If the control element indicates activation of the duplication, the first mapping restrictions are applied to the first logical channel and the second mapping restrictions are applied to the second logical channel. If the control element indicates deactivation of the duplication, the first mapping restrictions are lifted from the first logical channel and the second mapping restrictions are lifted from the second logical channel.

Abstract: A wireless device receives configuration parameters indicating data bearers each identified by a data bearer identifier. The data bearers comprise: first data bearer(s) configured with duplication; and second data bearer(s) that are not configured with duplication. A received control element comprises duplication activation bits comprising an activation bit for a first data bearer of the first data bearer(s). A first position of the activation bit in the control element identifies a second position of a first data bearer identifier in an ordered list of data bearer identifiers of the first data bearer(s) configured with the duplication. The ordered list of data bearer identifiers excludes the second data bearer(s). In response to the duplication being activated for the first data bearer: a first packet via a first cell; and a duplicate of the first packet is transmitted via a second cell different from the first cell.

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 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.
