Power control for configured uplink grant

A base station comprising:

• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, cause the base station to:
• transmit, to a wireless device, one or more radio resource control (RRC) messages comprising one or more configuration parameters, wherein the one or more configuration parameters comprise:
• a pathloss reference signal update parameter that enables an activation command to update pathloss reference signals of a physical uplink shared channel (PUSCH), and indicates:
• a plurality of sounding reference signal (SRS) resource sets;
• a plurality of pathloss reference signals for pathloss estimation of SRS transmissions;
• and
• usages for the plurality of SRS resource sets, wherein each SRS resource set of the plurality of SRS resource sets is associated with a respective usage of the usages;
• transmit the activation command updating a pathloss reference signal, among the plurality of pathloss reference signals, for a first SRS resource set of the plurality of SRS resource sets, wherein the activation command is configured for the wireless device to:
• update the pathloss reference signal for a second SRS resource set based on a first usage of the first SRS resource set and a second usage of the second SRS resource set being the same, wherein the first usage and the second usage are Antenna Switching, and not update the pathloss reference signal for a third SRS resource set among the plurality of SRS resource sets based on a third usage of the third SRS resource set being different from the first usage of the first SRS resource set;
• determine a transmission power used by the wireless device for a transport block of a Type 1 configured uplink grant based on the pathloss reference signal mapped to a sounding reference signal PUSCH (SRI-PUSCH) power control parameter set with index zero;
• and
• receive, from the wireless device, the transport block with the transmission power.

A system comprising:

• a base station comprising one or more first processors and memory storing instructions that, when executed by the one or more first processors, cause the base station to:
• transmit one or more radio resource control (RRC) messages comprising one or more configuration parameters, wherein the one or more configuration parameters comprise:
• a pathloss reference signal update parameter that enables an activation command to update pathloss reference signals of a physical uplink shared channel (PUSCH), and indicates:
• a plurality of sounding reference signal (SRS) resource sets;
• a plurality of pathloss reference signals for pathloss estimation of SRS transmissions;
• and
• usages for the plurality of SRS resource sets, wherein each SRS resource set of the plurality of SRS resource sets is associated with a respective usage of the usages;
• transmit the activation command updating a pathloss reference signal, among the plurality of pathloss reference signals, for a first SRS resource set of the plurality of SRS resource sets;
• and
• a wireless device comprising one or more second processors and memory storing instructions that, when executed by the one or more second processors, cause the wireless device to:
• receive, from the base station, the one or more RRC messages comprising the one or more configuration parameters;
• receive, from the base station, the activation command;
• based on the activation command received, determine a second SRS resource set among the plurality of SRS resource sets;
• and
• update the pathloss reference signal for the second SRS resource set based on a first usage of the first SRS resource set and a second usage of the second SRS resource set being the same, wherein the first usage and the second usage are Antenna Switching, and not update the pathloss reference signal for a third SRS resource set among the plurality of SRS resource sets based on a third usage of the third SRS resource set being different from the first usage of the first SRS resource set;
• determine a transmission power for a transport block of a Type 1 configured uplink grant based on the pathloss reference signal mapped to a sounding reference signal PUSCH (SRI-PUSCH) power control parameter set with index zero;
• and
• transmit, to the base station, the transport block with the transmission power.
