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： 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 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： 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 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 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： A wireless device receives, from a base station, one or more messages indicating: a number of repetition transmission occasions for uplink transmission of a transport block; and an interval for switching uplink transmissions between a first panel and a second panel. Based on the interval, a determination is made of: a first portion of the number of repetition transmission occasions for uplink transmission of the transport block; and a second portion of the number of repetition transmission occasions for uplink transmission of the transport block. The first portion of the number of repetition transmission occasions of the transport block is transmitted via the first panel. The second portion of the number of repetition transmission occasions of the transport block is transmitted via the second panel.

摘要： Described are embodiments for uplink transmission using multiple panels. In an embodiment, a wireless device receives configuration parameters indicating a transmission configuration indication (TCI) state index is associated with: a first TCI state, of a first antenna panel, for uplink transmissions; and a second TCI state, of a second antenna panel, for uplink transmissions. The wireless device receives a command indicating the TCI state index and determines, based on the configuration parameters, the first TCI state and the second TCI state associated with the TCI state index indicated in the command. The wireless device transmits, via the first antenna panel, one or more first transport blocks based on the first TCI state. The wireless transmits, via the second antenna panel, one or more second transport blocks based on the second TCI state.

摘要： A downlink control information (DCI) is received. The DCI indicates one or more transmission configuration indication (TCI) states. A first pathloss between a transmission reception point (TRP) and a first panel of a wireless device is measured based on one or more pathloss reference signals (RSs). A second pathloss between the TRP and a second panel of the wireless device is measured based on the one or more pathloss RSs. A pathloss is determined based on a quantity of the one or more TCI states indicated by the DCI. The pathloss is a combined pathloss based on the first pathloss and the second pathloss in response to the quantity being equal to one. The pathloss is one of the first pathloss and the second pathloss in response to the quantity being greater than one. A transport block is transmitted with a transmission power based on the pathloss.

摘要： A wireless device receives one or more messages comprising configuration parameters indicating a plurality of configured grant configurations for one or more bandwidth parts (BWPs) of a cell. A downlink control information is received. The downlink control information indicates activation or release of a first configured grant configuration, among the plurality of configured grant configurations, for a first BWP of the one or more BWPs. A confirmation indicating that the wireless device received the downlink control information indicating the activation or release of the first configured grant configuration is transmitted. The confirmation comprises at least one of: an identifier of the first BWP; and an identifier of a sub-band of the first BWP.
