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, 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： 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 receives, from a base station, configuration parameters indicating a plurality of first reference signals (RSs) including a first RS associated with a plurality of second RSs. Based on signal strengths of the plurality of first RSs, the first RS is selected from the plurality of first RSs. Based on signal strengths of the plurality of second RSs, a second RS is selected from the plurality of second RSs associated with the first RS. Based on the selected second RS, the wireless device transmits a random access preamble.

摘要： In an embodiment, a wireless device receives configuration parameters of a plurality of uplink (UL) transmission configuration indicator (TCI) codepoints. A first codepoint of the plurality of UL TCI codepoints indicates that an activated downlink (DL) TCI state is applicable for UL signal transmission. A second codepoint of the plurality of UL TCI codepoints indicates that a sounding reference signal resource indicator (SRI) is applicable for UL signal transmission. The wireless device receives a control command indicating a codepoint and determines a spatial domain filter based on the indicated codepoint being one of the plurality of UL TCI codepoints. The spatial domain filter is determined using: the activated DL TCI state based on the indicated codepoint being the first codepoint; and the SRI based on the indicated codepoint being the second codepoint. The wireless device transmits the UL signal using the determined spatial domain filter.

摘要： A wireless device receives a first message indicating a first transmission configuration indicator (TCI) state being applicable at a first time for receiving a downlink control channel. A second message is received and indicates a common TCI state being applicable at a second time for: receiving the downlink control channel; and receiving downlink data via a downlink shared channel. The wireless device determines that the second message is received after the first message and that the second time is earlier than the first time. Based on the determining, the downlink control channel is received based on the common TCI state and the downlink data is received via the downlink shared channel based on the common TCI state.

摘要： Described are embodiments for frequency selective transmission. In an embodiment, a wireless device receives a downlink control information indicating a transmission via uplink resources comprising sub-bands; and a sounding reference signal resource indicator (SRI). The wireless device selects, based on the SRI, one or more sounding reference signal (SRS) resources. Uplink precoders are determined for the transmission. The uplink precoders include an uplink precoder that is determined, for each respective sub-band of the sub-bands, based on a transmission precoder of the one or more SRS resources transmitted via the respective sub-band. The wireless device transmits, based on the determined uplink precoders, a transport block of the transmission via the uplink resources.
