Uplink power control

An apparatus comprising:

• a receiver that:
• receives a first message that configures a set of reference signal resources, wherein each reference signal resource of the set of reference signal resources comprises a downlink reference signal resource or an uplink sounding reference signal resource, and each reference signal resource of the set of reference signal resources is associated with a corresponding uplink transmission beam pattern;
• and
• receives scheduling information for a first uplink transmission, wherein the first uplink transmission is associated with a first reference signal resource of the set of reference signal resources;
• and
• a processor that:
• determines a first uplink transmission beam pattern associated with the first reference signal resource;
• determines a first configured maximum output power for the first uplink transmission beam pattern, wherein the first configured maximum output power is based on a first antenna array property associated with the first uplink transmission beam pattern;
• determines a first transmit power for the first uplink transmission based on the first configured maximum output power;
• and
• performs the first uplink transmission using the first uplink transmission beam pattern based on the first transmit power.
