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.

摘要： A wireless device receives one or more RRC messages comprising configuration parameters of a cell. The configuration parameters indicate uplink BWPs of an uplink carrier of the cell. The uplink BWPs comprise a first uplink BWP and a second uplink BWP. The configuration parameters further indicate a sidelink BWP of the uplink carrier of the cell. A numerology of the second uplink BWP is different than a numerology of the sidelink BWP. The wireless device activates the first uplink BWP. The wireless device activates the sidelink BWP. The wireless device switches from the first uplink BWP to the second uplink BWP as an active uplink BWP. The wireless device deactivates, based on the switch, the sidelink BWP.

摘要： A first wireless device receives one or more messages indicating a distance threshold for a distance between: the first wireless device; and a second wireless device. A control information is received. The control information indicates transmission of a measurement report of a sidelink between: the first wireless device; and the second wireless device. Based on the distance threshold and a distance between the first wireless device and the second wireless device, a determination is made to transmit the measurement report of the sidelink. The measurement report is transmitted to the second wireless device via the sidelink.

摘要： Described are embodiments for frequency selective transmission. In an embodiment, a wireless device receives a downlink control information indicating a transmission via uplink resources comprising sub-bands; and a sounding reference signal resource indicator (SRI). The wireless device selects, based on the SRI, one or more sounding reference signal (SRS) resources. Uplink precoders are determined for the transmission. The uplink precoders include an uplink precoder that is determined, for each respective sub-band of the sub-bands, based on a transmission precoder of the one or more SRS resources transmitted via the respective sub-band. The wireless device transmits, based on the determined uplink precoders, a transport block of the transmission via the uplink resources.

摘要： A wireless device may receive one or more radio resource control (RRC) messages. 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 radio resource control message comprising configuration parameters of a plurality of cells. An activation command indicating activation of a plurality of secondary cells (SCells) of the plurality of cells is received. A first downlink control information (DCI), comprising a power saving indication bitmap, is received. Each bit of the power saving indication bitmap indicates whether to monitor a downlink control channel on a corresponding activated SCell of the plurality of SCells. The wireless device starts monitoring a downlink control channel of an activated SCell of the activated SCells, in response to a bit, of the power saving indication bitmap, corresponding to the activated SCell, indicating monitoring the downlink control channel. A second DCI is received via the downlink control channel.

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.
