Power control parameter set and pathloss reference signal for wireless device

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, a medium access control control element (MAC CE) indicating:
• a power control parameter set of power control parameter sets for uplink transmissions by the wireless device via physical uplink shared channel (PUSCH) resources;
• and
• a pathloss reference signal (RS), of pathloss RSs for the uplink transmissions via the PUSCH resources, associated with the power control parameter set;
• transmit downlink control information indicating:
• a PUSCH resource;
• and
• the power control parameter set;
• and
• receive an uplink signal via the PUSCH resource, wherein a transmission power of the uplink signal is based on the pathloss RS associated with the power control parameter set.
