摘要： A wireless device receives a DCI from a base station. The DCI comprises a power control command of an uplink shared channel, a CSI request field, a hybrid automatic repeat request process number, and a redundancy version. Validation of the DCI for an activation of a semi-persistent CSI reporting is performed based on: a radio network temporary identifier of the semi-persistent CSI reporting, the hybrid automatic repeat request process number being set to a first value, and the redundancy version being set to a second value. The semi-persistent CSI reporting indicated by the CSI request field is activated in response to the validation being achieved. A semi-persistent CSI report is transmitted, based on the activated semi-persistent CSI reporting, via the uplink shared channel with a transmission power determined based on the power control command.

摘要： A wireless device may receive a first downlink control information (DCI). The first DCI may indicate a first plurality of resources for one or more uplink transport blocks. A group common DCI may be received via a common control channel. The group common DCI may comprise a field indicating an uplink pre-emption indication. The uplink pre-emption indication may indicate a second plurality resources. One or more first resources may be punctured from the first plurality of resources. The one or more first resources may be overlapping resources of the first plurality of resources and the second plurality of resources. The one or more uplink transport blocks may be transmitted via remaining resources of the first plurality of resources after the puncturing.

摘要： A base station distributed unit may determine that a first uplink timing advance value for a first cell of a wireless device is different than a second uplink timing advance value for a second cell of the wireless device. The first cell and the second cell may belong to a first timing advance group. The base station distributed unit may transmit a first message to a base station central unit in response to the determining. The first message may comprise one or more information elements indicating a reconfiguration of a timing advance group configuration for the wireless device. The base station distributed unit may receive a radio resource control message from the base station central unit based on the reconfiguration for the wireless device.

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).

摘要： A wireless device receives message(s) comprising: a first value for an uplink hybrid automatic repeat request (HARQ) round-trip-time (RTT) timer; and a second value for an uplink discontinuous reception (DRX) retransmission timer. A transport block is transmitted via an uplink data channel. The uplink HARQ RTT timer is started with the first value in response to transmitting the transport block. The first value indicates a first number of symbols. The uplink DRX retransmission timer is started with the second value in response to the uplink HARQ RTT timer expiring. The second value indicates of a second number of slot lengths. A downlink control channel is monitored while the uplink DRX retransmission timer is running.

摘要： A base station central unit receives message(s) for a wireless device from a second base station. The message(s) comprise a first aggregate maximum bit rate of the wireless device at the first base station. The message(s) comprise a PDCP packet duplication parameter indicating that a first packet flow comprises duplicated PDCP packets. The first base station receives the duplicated PDCP packets of the first packet flow from the second base station. The first base station transmits the duplicated PDCP packets to the wireless device. The first base station determines that a bit rate between the wireless device and the first base station exceeds the first aggregate maximum bit rate. The determining ignores, based on the PDCP packet duplication parameter, the duplicated PDCP packets. The first base station limits the bit rate between the wireless device and the first base station based on the determining.

摘要： A base station distributed unit receives information elements (IEs) from a base station central unit. The IEs comprise: at least one bearer configuration information element indicating that PDCP packet duplication is configured for at least one first bearer of a wireless device; and at least one information element indicating activation of the PDCP packet duplication of the at least one first bearer. The base station distributed unit transmits a medium access control control element indicating the activation of the PDCP packet duplication of the at least one first bearer to the wireless device in response to the at least one information element indicating the activation of the PDCP packet duplication. Based on the medium access control control element, the base station distributed unit receives: PDCP packets of the at least one first bearer; and duplicated PDCP packets of the at least one first bearer.

摘要： A wireless device may receive one or more messages comprising a duplication configuration parameter for a bearer. A transport block may be received. The transport block may comprise a control element indicating activation of the duplication for the bearer. In response to receiving the control element, a cell with an uplink control channel may be interrupted. During the interrupting, a hybrid automatic repeat request feedback corresponding to the transport block may be transmitted via the cell.

摘要： A wireless device receives message(s) comprising configuration parameter(s) of a first cell and a second cell. The configuration parameter(s) indicate a plurality of bandwidth parts (BWPs) of the first cell. A first uplink BWP of the plurality of BWPs is activated as an active uplink BWP. A beam failure recovery procedure for the second cell is initiated based on detecting a beam failure. A determination that the first uplink BWP is not configured with one or more beam failure recovery resources for the second cell is made. The active uplink BWP of the first cell is switched, based on the determination, from the first uplink BWP to a second uplink BWP, of the plurality of BWPs, configured with the one or more beam failure recovery resources for the second cell. An uplink signal indicating the beam failure is transmitted via the second uplink BWP.

摘要： A wireless device receives message(s) from a base station comprising configuration parameters of a first uplink bandwidth part of a cell. The configuration parameters comprise: a bandwidth part configuration parameter of the first uplink bandwidth part, and random access channel parameters of a random access channel resource. A preamble is transmitted via the random access channel resource on the first uplink bandwidth part. A random access radio network temporary identifier (RA-RNTI) is determined based on the bandwidth part configuration parameter and one or more of the random access channel parameters. A downlink control channel is monitored for a downlink control information addressed to the RA-RNTI in response to the determining. The downlink control information indicates a downlink radio resource of a random access response is received. The random access response is received via the downlink radio resource in response to the downlink control information.
