摘要： A wireless device receives first configuration parameters of a first bandwidth part and a second bandwidth part of a licensed cell; and second configuration parameters of a third bandwidth part and a fourth bandwidth part of an unlicensed cell. A first downlink control information indicating switching from the first bandwidth part to the second bandwidth part as an active bandwidth part is received. A second downlink control information indicating switching from the third bandwidth part to the fourth bandwidth part as an active bandwidth part is received. Based on the receiving the first downlink control information: the wireless device switches from the first bandwidth part to the second bandwidth part; and does not transmit a confirmation. Based on the receiving the second downlink control information, the wireless device switches from the third bandwidth part to the fourth bandwidth part; and transmits a confirmation.

摘要： A wireless device receives one or more messages comprising spatial relation configuration parameters of a physical uplink control channel. The configuration parameters indicate a plurality of reference signal (RS) sets. An RS set of the plurality of RS sets comprises one or more RSs. A medium access control control element, activating the RS set of the plurality of RS sets, is received. A downlink control information, indicating an RS of the RS set, is received. A spatial domain transmission filter, for the physical uplink control channel, is determined based on based on the RS. Uplink control information is transmitted, via the physical uplink control channel, based on the spatial domain transmission filter.

摘要： A first access node receives, from a second access node, at least one message comprising configuration parameters of a first cell of a third access node. The third access node is a child node associated with the second access node. The third access node communicates with the second access node via at least one backhaul link. The configuration parameters comprise an identifier indicating the first cell and backhaul information of the at least one backhaul link. The first access node determines, based on the backhaul information, a handover of a wireless device to the first cell. The first access node transmits, to the second access node, a message requesting the handover of the wireless device to the first cell.

摘要： A wireless device receives configuration parameters of one or more configured grants of an unlicensed cell. The wireless device receives a downlink control information indicating an uplink grant for a first TB corresponding to a first HARQ process. The wireless device stores, based on a first LBT procedure indicating a busy channel, the first TB in a first HARQ buffer associated with the first HARQ process. The first LBT is for a scheduled transmission of the first TB. The wireless device flushes, based on a second LBT procedure indicating a busy channel, a second HARQ buffer associated with a second HARQ process. The second LBT procedure is for a scheduled transmission of a second TB via a first configured grant of the one or more configured grants.

摘要： A wireless device receives one or more messages comprising configuration parameters. The configuration parameters indicate pathloss reference signals (RSs) for PUSCH pathloss estimation for transmissions via first and second panels. A medium access control control element (MAC CE) is received. The MAC CE indicates first pathloss RSs of the plurality of pathloss RSs for the first panel. The MAC CE indicates second pathloss RSs of the plurality of pathloss RSs for the second panel. A downlink control information (DCI) is received. The DCI indicates a first pathloss RS. The DCI indicates a second pathloss RS. The wireless device transmits, via the first panel, a first uplink transport block with a first uplink transmission power determined based on the first pathloss RS. The wireless device transmits, via the second panel, a second uplink transport block with a second uplink transmission power determined based on the second pathloss RS.

摘要： A wireless device receives configuration parameters of physical uplink control channel (PUCCH) resources of a cell. The PUCCH resources are grouped into a plurality of PUCCH resource groups. A downlink control information (DCI), indicating an uplink grant, is received via a control resource set. A PUCCH resource group is selected, based on the control resource set, from the plurality of PUCCH resource groups. A spatial relation information corresponding to a first PUCCH resource of the selected PUCCH resource group is determined. An uplink transport block is transmitted via the uplink grant based on the spatial relation information.

摘要： A wireless device receives one or more first radio resource control (RRC) messages. The first RRC messages comprise one or more configuration parameters of a first cell and a second cell. A second RRC message is received. The second RRC message indicates a first change of a first active bandwidth part (BWP) of the first cell. Processing of the second RRC message is completed. A determination is made that the completing occurs during a time duration of a second change of a second active BWP of the second cell. Based on the determining, the first change of the first active BWP is delayed until the second change of the second active BWP is completed.

摘要： A wireless device receives a radio resource control message from a base station. The radio resource control message comprises one or more configuration parameters for a random access channel. A downlink control information is received that comprises a field indicating a slot format indication, for a slot, among a plurality of SFIs. The plurality of SFIs indicate uplink, flexible, and random access symbols. The wireless device determines radio resources of one or more random access channel occasions of the slot based on the one or more configuration parameters and at least one random access symbol indicated by the slot format indication for the slot. A preamble is transmitted via the radio resources of the one or more random access channel occasions.
