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 one or more messages from a base station. The one or more messages comprise configuration parameters of a cell. The configuration parameters indicate: a plurality of slot format combinations of the cell; a channel occupancy time (COT) radio network temporary identifier (RNTI); and an index of a field in a downlink control information (DCI) for the cell. The DCI scrambled by the COT-RNTI is received. A COT structure, for the cell, is determined based on one of the plurality of slot format combinations indicated by the field in the DCI associated with the index. A transport block is transmitted, via the cell, on uplink resources according to the COT structure.

摘要： A wireless device receives one or more messages indicating a handover to a cell of a second base station. The one or more messages comprise configuration parameters of the cell. The configuration parameters indicate a plurality of power control parameter sets (PCPSs). The configuration parameters indicate a plurality of downlink reference signals. A downlink reference signal of the plurality of downlink reference signals is determined based on measurements of the plurality of downlink reference signals. A PCPS is selected from the plurality of PCPSs. The PCPS is associated with the downlink reference signal. An uplink transmission power is determined, based on the PCPS, for a physical uplink shared channel (PUSCH) of the cell. An uplink transport block is transmitted with the uplink transmission power via the PUSCH of the cell.

摘要： A wireless device receives one or more messages comprising configuration parameters. The configuration parameters indicate: a first plurality of bandwidth parts (BWPs) of a Uu link; and a second plurality of BWPs of a sidelink. A downlink control information (DCI) is received. The DCI indicates a first BWP of the first plurality of BWPs. The wireless device selects a second BWP, from the second plurality of BWPs, associated with the first BWP. In response to the reception of the DCI: the first BWP is activated; and the second BWP is activated.

摘要： A wireless device receives, from a base station, one or more messages indicating: a number of repetition transmission occasions for uplink transmission of a transport block; and an interval for switching uplink transmissions between a first panel and a second panel. Based on the interval, a determination is made of: a first portion of the number of repetition transmission occasions for uplink transmission of the transport block; and a second portion of the number of repetition transmission occasions for uplink transmission of the transport block. The first portion of the number of repetition transmission occasions of the transport block is transmitted via the first panel. The second portion of the number of repetition transmission occasions of the transport block is transmitted via the second panel.

摘要： A wireless device receives one or more messages. The one or more messages comprise configuration parameters of a cell. The configuration parameters indicate: a plurality of slot format combinations of the cell; a plurality of reference signals (RS) of the cell; and a channel occupancy time (COT) radio network temporary identifier (RNTI). The wireless device receives a downlink control information (DCI) scrambled by the COT-RNTI indicating a slot format combination of the plurality of slot format combinations, for an RS of the plurality of RSs. A channel occupancy time (COT) structure is determined for the RS based on the slot format combination. A transport block is transmitted, via uplink resources of the cell, based on the COT structure.

摘要： A wireless device receives one or more radio resource control (RRC) messages comprising configuration parameters. The configuration parameters indicate a first secondary cell (SCell) group comprising one or more first cells and a second SCell group comprising a plurality of second cells. The wireless device activates, in a non-dormant state, the one or more first cells and the plurality of second cells. In response to receiving a downlink control information indicating transitioning the first SCell group to a dormant state, the wireless device transitions the one or more first cells to the dormant state and maintains the plurality of second cells in the non-dormant state.

摘要： A wireless device monitors a first radio link quality on a first plurality of reference signals of a bandwidth part of a cell in a non-power-saving state. The wireless device detects at least a first synchronization status based on the monitoring the first radio link quality. The wireless device receives a downlink control information indicating transitioning from the non-power-saving state to a power saving state. The wireless device monitors, based on the downlink control information, a second radio link quality on a second plurality of reference signals of the bandwidth part. The wireless device detects at least a second synchronization status based on the monitoring the second radio link quality.

摘要： A wireless device may receive one or more messages comprising configuration parameters of a cell. A reference duration for contention window adjustment may be determined based on the configuration parameters. The reference duration may be from a beginning of a channel occupancy of a first transmission burst and until an end of a first slot. The at least one physical uplink shared channel (PUSCH) may be transmitted. A contention window value may be determined based on a plurality of new data indicators (NDIs) received in a plurality of uplink grants corresponding to a plurality of first transport blocks transmitted by the wireless device during the reference duration. The wireless device may perform a listen before talk procedure based on the contention window value. One or more second transport blocks may be transmitted based on the listen before talk procedure indicating a clear channel.
