摘要： A wireless device receives, from a base station, one or more messages comprising configuration parameters indicating a sounding reference signal (SRS) resource set. A downlink control information is received. The downlink control information comprising an SRS resource indicator (SRI) and an uplink transmission configuration indicator (UL-TCI). The SRI indicates one or more SRS resources of the SRS resource set. In response to the UL-TCI being equal to a predefined value, a determination is made of an uplink spatial domain transmission filter based on the one or more SRS resources of the SRS resource set. A transport block with the uplink spatial domain transmission filter is transmitted via a physical uplink shared channel.

The RRC messages may indicate a first transmission and reception point (TRP) of a cell, a second TRP of the cell, and one or more first beam failure recovery parameters indicating one or more first reference signals for first TRP. The wireless device may determine a first beam failure of the first TRP based on the one or more first reference signals indicated by the one or more first beam failure recovery parameters. The wireless device may transmit an uplink signal via the second TRP of the cell indicating a link recovery request for the first TRP. The wireless device may receive an uplink grant for uplink data. The wireless device may transmit the uplink data indicating a candidate beam of the first TRP.

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 transmits uplink data via a first configured grant resource of a first cell of a plurality of cells. The wireless device determines a second cell from the plurality of cells to transition from a dormant state to a non-dormant state, where the determining is based on the second cell being configured with a control resource set for receiving uplink grants for retransmission of the uplink data. In response to the transmitting, the wireless device transitions the second cell from the dormant state to the non-dormant state. The wireless device receives an uplink grant via the second cell, wherein the uplink grant indicates a radio resource. Based on the uplink grant, the wireless device retransmits the uplink data via the radio resource.

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 receives one or more radio resource control messages comprising configuration parameters for a cell. The configuration parameters indicate a plurality of coreset groups corresponding to a plurality of transmission and reception points (TRPs). Each coreset in the plurality of coreset groups is associated with a transmission configuration indicator (TCI) state. A coreset group of the plurality of coreset groups is selected for a radio link monitoring of the cell. The selection is in response to the coreset group comprising a coreset with a pre-defined index value. One or more reference signals are monitored based on one or more TCI states of one or more coresets of the coreset group.

摘要： A wireless device receives configuration parameters comprising first parameters of downlink RSs and second parameter indicating that a default beam is used for uplink transmission. A DCI indicating a first uplink transmission via a PUSCH resource is received. A spatial relation information, for the first uplink transmission, is determined to be associated with one of the downlink reference signals in response to the second parameter indicating that the default beam is used. A transport block is transmitted via the PUSCH resource according to the spatial relation information.

摘要： A wireless device receives configuration parameters of a cell comprising: a first bandwidth part; and a second bandwidth part. A downlink control information is received. The downlink control information indicates: a priority of a transport block; and a hybrid automatic repeat request (HARQ) feedback timing of a HARQ feedback of the transport block. After receiving the downlink control information (DCI) and before the HARQ feedback timing, the active bandwidth part is switched from the first bandwidth part to the second bandwidth part. The HARQ feedback is transmitted in response to the priority of the transport block being associated with a first service type.

摘要： In some embodiments, a wireless device receives, from a base station, a power offset value for power control of repetition occasions of a transport block. The wireless device receives a downlink control information indicating a sequence of redundancy versions (RVs). and a quantity of the repetition occasions. Then, the wireless device determines: a first transmission power, based on the power offset value and the RVs, for one or more first repetition occasions of the repetition occasions; and a second transmission power, based on the RVs, for one or more second repetition occasions of the repetition occasions. The wireless device transmits the transport block: via the one or more first repetition occasions and with the first transmission power; and via the one or more second repetition occasions and with the second transmission power.
