    摘要: A wireless device receives a timer value of a DRX on duration timer for a DRX operation; radio resources of a reference signals for a transmission of a layer 1 reference signal received power report; and a report indicator indicating the transmission of the layer 1 reference signal received power report is limited to a time period when the DRX on duration timer is running. The layer 1 reference signal received power report is transmitted at a first time based on the DRX on duration timer running at a predefined time period before the first time. The layer 1 reference signal received power report includes a layer 1 reference signal received power value and a reference signal resource index associated with one of the reference signal(s). Based on the report indicator, transmitting of the layer 1 reference signal received power report at a second time is skipped in response to the DRX on duration timer not running at the predefined time period before the second time.

    摘要: A wireless device may receive configuration parameters for configured uplink transmissions via a plurality of resources. A first uplink transmission may be associated with a first resource in the plurality of resources and may be associated with a first HARQ process number. The wireless device may cancel a trigger for transmitting a buffer status report and create a first packet comprising the buffer status report for transmission via the first resource. The wireless device may receive, before a scheduled transmission of the first packet, a downlink control information for transmission of a second packet. The second packet may be associated with the first HARQ process number. In response to the downlink control information, the wireless device may drop the scheduled transmission of the first packet via the first resource and trigger the trigger for transmitting the buffer status report in response to receiving the downlink control information.

    摘要: A base station transmits to a wireless device, a first request to measure synchronization signal(s) of a first cell. The base station receives from the wireless device, measurement report(s) of at least one synchronization signal of the synchronization signal(s). The base station transmits to the wireless device, a second request to measure CSI-RS(s) of the first cell. The base station receives from the wireless device, second measurement report(s) of the CSI-RS(s). The second measurement report(s) are generated in response to the second request. The base station selects first CSI-RS(s) of the CSI-RS(s) based on the second measurement report(s). The base station transmits a downlink control information to the wireless device via one or more control channels. The downlink control information initiates a random access procedure of the first cell. The downlink control information comprises an indication of the first CSI-RS(s).
