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 one or more radio resource control messages. The one or more radio resource control messages indicating: a first control resource set (coreset) group; a second coreset group; a first physical uplink control channel (PUCCH) cell associated with a first index indicating the first coreset group; and a second PUCCH cell associated with a second index indicating the second coreset group. one or more transport blocks are received. A determination is made of a PUCCH cell for transmitting hybrid automatic repeat request (HARQ) feedback of the one or more transport blocks. The determining comprises: determining the first PUCCH cell in response to the one or more transport blocks being scheduled via the first coreset group; and determining the second PUCCH cell in response to the one or more transport blocks being scheduled via the second coreset group. The HARQ feedback is transmitted via the determined PUCCH cell.

摘要： The wireless device receives one or more radio resource control messages comprising configuration parameters of a cell. The configuration parameters indicate: a first set of transmission time intervals configured for a first control resource set (coreset) group of the cell; a first transmission configuration indicator (TCI) state of the first coreset group; a second set of transmission time intervals configured for a second coreset group of the cell; and a second TCI state of a second coreset group. A first downlink control information (DCI) comprising an assignment of a resource of the cell is received. A TCI state for the resource is selected, based on which of the first set of transmission time intervals or the second set of transmission time intervals overlaps in time with the resource, one of: the first TCI state; or the second TCI state. Based on the TCI state, data is received via the resource.

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： A wireless device receives configuration parameters indicating: a plurality of hybrid automatic repeat request (HARQ) processes of a cell; a subset of the plurality of HARQ processes; and a HARQ process identifier offset. A downlink control information (DCI) comprising a first HARQ process identifier and a resource assignment is received. The first HARQ process identifier indicates a HARQ process in the subset of the plurality of HARQ processes. A second HARQ process identifier is determined based on the first HARQ process identifier and the HARQ process identifier offset. The second HARQ process identifier indicates a second HARQ process of the plurality of HARQ processes. Based on the resource assignment, a transport block of a HARQ buffer associated with the second HARQ process is transmitted.

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 from a second base station, a RRC message comprising access information, for a handover to a first cell of a first base station, indicating that a first timing advance of a first beam of the first cell is a timing advance of a first timing advance group of a secondary cell group and that a second timing advance of a second beam of the first cell is a timing advance of a second timing advance group of the secondary cell group. The wireless device selects, as a selected beam, one of the first beam and the second beam. The wireless device transmits transport blocks, via the selected beam of the first cell, using one of: the first timing advance in response to the selected beam being the first beam; and the second timing advance in response to the selected beam being the second beam.

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 wireless device receives one or more radio resource control messages from a base station. The one or more radio resource control messages comprising configuration parameters of a cell for beam failure recovery. The configuration parameters indicate: a serving beam set, a plurality of candidate beam sets, and a monitoring priority of the plurality of candidate beam sets. A beam failure instance of the serving beam set is detected. In response to the detection, a first candidate beam set of the plurality of candidate beam sets is determined based on the monitoring priority. A candidate beam is selected from the first candidate beam set. A preamble associated with the candidate beam for the beam failure recovery is transmitted.
