摘要： A wireless device receives message(s) comprising: a first value for an uplink hybrid automatic repeat request (HARQ) round-trip-time (RTT) timer; and a second value for an uplink discontinuous reception (DRX) retransmission timer. A transport block is transmitted via an uplink data channel. The uplink HARQ RTT timer is started with the first value in response to transmitting the transport block. The first value indicates a first number of symbols. The uplink DRX retransmission timer is started with the second value in response to the uplink HARQ RTT timer expiring. The second value indicates of a second number of slot lengths. A downlink control channel is monitored while the uplink DRX retransmission timer is running.

摘要： In some embodiments, a wireless device receives a plurality of downlink control information (DCIs) via a plurality of resource block (RB) sets of a bandwidth part of a cell. The plurality of DCIs indicate downlink radio resources. The wireless device receives a transport block via the downlink radio resources. Based on RB set indexes of the plurality of RB sets, the wireless device determines a DCI from the plurality of DCIs. Then, the wireless device transmits feedback information, for the transport block, via an uplink control channel resource determined based on the DCI.

摘要： Described are embodiments for selecting a preamble for a random access procedure. In an embodiment, a wireless device receives one or more configuration parameters of physical random access channel (PRACH) occasions for the random access procedure. One or more PRACH occasions of the PRACH occasions correspond to a respective RS of a plurality of RSs. The wireless device determines a RS, from the plurality of RSs, based on a reference signal received power (RSRP) value of the RS, and a transmission power reduction value associated with the RS. The wireless device determines a PRACH occasion, associated with the RS, from the PRACH occasions. Then, the wireless device transmits, via the PRACH occasion, a preamble for the random access procedure.

摘要： A wireless device receives one or more first radio resource control (RRC) messages. The first RRC messages comprise one or more configuration parameters of a first cell and a second cell. A second RRC message is received. The second RRC message indicates a first change of a first active bandwidth part (BWP) of the first cell. Processing of the second RRC message is completed. A determination is made that the completing occurs during a time duration of a second change of a second active BWP of the second cell. Based on the determining, the first change of the first active BWP is delayed until the second change of the second active BWP is completed.

摘要： A wireless device receives one or more messages comprising configuration parameters. The configuration parameters indicate: a plurality of bandwidth parts (BWPs) comprising a first BWP and a second BWP; and a timer value for a BWP inactivity timer. The BWP inactivity timer associated with the timer value starts in response to switching to the first BWP as an active BWP. A beam failure recovery procedure is initiated based on reaching a number of beam failure instance indications for the first BWP. Based on an expiry of the BWP inactivity timer during the beam failure recovery procedure: the beam failure recovery procedure for the first BWP is aborted; and the active BWP is switched from the first BWP to the second BWP.

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 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 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 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.
