摘要： A wireless device receives, from a base station, one or more messages indicating: a control resource set (coreset) of a bandwidth part of a cell; and a first reference signal (RS) associated with the coreset. A downlink control channel in the coreset is monitored based on the first RS. A control command indicating a group of one or more second RSs is received. The wireless device determines that the group of the one or more second RSs does not include the first RS. In response to the determining, the wireless device stops monitoring the downlink control channel in the coreset.

摘要： A wireless device may receive one or more messages comprising one or more configuration parameters for a cell. The one or more configuration parameters may indicate a sounding reference signal (SRS) resource for a configured uplink grant. An SRS resource set may comprise the SRS resource. The one or more configuration parameters may comprise a parameter that enables using default transmission parameters for SRS transmissions. The one or more configuration parameters may indicate no pathloss reference signal. The wireless device may transmit, with a transmission power determined based on a pathloss reference signal associated with the SRS resource set, a transport block of the configured uplink grant.

摘要： In an embodiment a wireless device receives configuration parameters, of a cell, indicating: a first reference signal (RS) of a first transmission reception point (TRP) of the cell; a second RS of a second TRP of the cell; random access channel (RACH) resources of a RACH of the cell; and a power offset value. The wireless device measures a first received power value of the first RS and measures a second received power value of the second RS. The wireless device selects, based on the measuring and the power offset value, an RS from the first RS and the second RS. Then, the wireless device transmits a preamble, associated with the selected RS, via the RACH resources.

摘要： A wireless device receives one or more messages including configuration parameters, for transmission configuration indicator (TCI) indication, of a first control resource set (coreset) and a second coreset. The wireless device receives, via the first coreset and based on a first TCI state, a first control command indicating a second TCI state. In response to the receiving the first control command: downlink transport blocks are received via a downlink shared channel and based on the second TCI state, a first downlink control channel is received via the first coreset and based on the first TCI state; and a second downlink control channel is received via the second coreset and based on the second TCI state.

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 selects a first a synchronization signal block (SSB), among SSBs of a cell, based on a signal quality measurement of the SSBs, and a second SSB, of the SSBs, based on the first SSB and a multiplexing pattern. The wireless device determines, based on the first SSB and the second SSB, monitoring occasions associated with a control resource set (coreset) to receive repetitions of downlink control information (DCI). The wireless device receives, via the determined monitoring occasions, one or more of the repetitions of the DCI.

摘要： A wireless device may receive one or more configuration parameters for a cell. The one or more configuration parameters may indicate a periodic resource configuration. The periodic resource configuration may be activatable by predetermined values of: a hybrid automatic repeat request process identifier (HARQ ID) field of a first downlink control information (DCI) format; and a redundancy version (RV) field of the first DCI format. The wireless device may receive a DCI based on a second DCI format without the HARQ ID field and/or the RV field. The wireless device may activate the periodic resource configuration based on: a size of the HARQ ID field of the DCI and/or the RV field of the DCI being zero; and the periodic resource configuration being in an inactive state.

摘要： A wireless device receives configuration parameters of a bandwidth part comprising resource block (RB) sets, each RB set having an RB index. The wireless device receives, during a downlink control channel monitoring occasion, a plurality of downlink control information (DCI)s and each DCI of the plurality of DCIs is received via a respective RB set of the RB sets. The wireless device transmits a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook comprising HARQ-ACK information bits corresponding to the plurality of DCIs, wherein the HARQ-ACK information bits are in order of indexes of RB sets corresponding to the DCIs.

摘要： A wireless device receives one or more messages comprising one or more configuration parameters. The one or more configuration parameters indicate: a plurality of control resource sets (coresets); a first group of search space sets for monitoring the plurality of coresets in a first mode; and a second group of search space sets for monitoring the plurality of coresets in a second mode. Reference signals for radio link monitoring are selected based on the first group of search space sets. The reference signals for the radio link monitoring are measured for both in the first mode and the second mode.

摘要： A wireless device triggers transmission of a scheduling request (SR) based on triggering a beam failure recovery (BFR) of a secondary cell. Aa configured transmission of the SR based on transmitting a medium access control protocol data unit (MAC PDU) is stopped. The transmission comprises a BFR medium access control control element (BFR MAC CE) comprising information of the BFR triggered prior to assembling of the MAC PDU.
