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 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 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 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 a radio resource control message. The radio resource control message comprises a periodicity of uplink resources of an uplink configured periodic grant. A buffer status report (BSR) for transmission is triggered in response to data becoming available for uplink transmission. The BSR indicates a size of the data. Based on the triggering of the BSR, an uplink scheduling request is triggered in response to receiving no additional resource for uplink transmission while the uplink resources for the uplink configured periodic grant are available. The scheduling request is transmitted.

Abstract: A wireless device receives parameters of a configured periodic grant. The parameters indicate: a timing offset and a symbol number; a first periodicity indicating a time interval between two subsequent resources; and demodulation reference signal parameters. One or more symbols of a resource of the configured periodic grant are determining based on the timing offset, the symbol number, and the first periodicity. One or more transport blocks are transmitted, via the resource of the configured periodic grant, employing the demodulation reference signal parameters.
