1. A method for uplink transmission, the method comprising:
transmitting, by a user equipment (UE) to a base station, a first sounding reference signal (SRS) according to a first power control set, the first power control set including a first UE-specific SRS initial target power, a first pathloss, a first pathloss compensation factor, and a first transmit power command,
the first power control set being determined based on a first set of operational properties, the first set of operational properties including first resource information for the first SRS, first numerology information for the first SRS, and a first downlink (DL) reference signal (RS) type for first pathloss estimation,
the first numerology information indicating at least a first subcarrier spacing (SCS) for determining the first power control set and a first cyclic prefix (CP) length for determining the first power control set,
the first resource information including at least one of:
a first configured resource index for the first SRS, or
first Quasi-Co-Location (QCL) information with a first downlink Channel State Information Reference Signal (CSI-RS); and
transmitting, by the UE to the base station, a second SRS according to a second power control set, the second power control set including a second UE-specific SRS initial target power, a second pathloss, a second pathloss compensation factor, and a second transmit power command,
the second power control set being determined based on a second set of operational properties, the second set of operational properties including second resource information for the second SRS, second numerology information for the second SRS, and a second DL RS type for second pathloss estimation,
the second numerology information indicating at least a second SCS for determining the second power control set and a second CP length for determining the second power control set,
the second resource information including at least one of:
a second configured resource index for the second SRS, or
second QCL information with a second CSI-RS.
