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： 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.

摘要： A wireless device receives configuration parameters indicating a first PDSCH processing capability value associated with a first power state of a cell, and a second PDSCH processing capability value associated with a second power state of the cell. The first PDSCH processing capability value indicates a first applicable gap between receiving a TB and transmitting an acknowledgement when the cell is in the first power state. The second PDSCH processing capability value indicates a second applicable gap between receiving a TB and transmitting an acknowledgement when the cell is in the second power state. A first TB is processed based on the first PDSCH processing capability value, when the cell in the first power state. A command is received indicating transitioning to the second power state. A second TB is processed based on the second PDSCH processing capability value, in response to transitioning to the second power state.

摘要： A wireless device receives a first downlink control information (DCI) comprising a first hybrid automatic request (HARQ) process identifier and a first new data indicator (NDI). A second DCI is received with the first HARQ process identifier and a second NDI. The second NDI is considered as toggled regardless of a value of the second NDI in response to the first DCI indicating postponing a HARQ acknowledgement transmission for a HARQ process identified by the first HARQ process identifier. The wireless device flushes a HARQ buffer associated with the HARQ process based on the second NDI being toggled.

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 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 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 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.
