Uplink power control

A method comprising:

• receiving, by use of a receiver, a first message that configures reception of scheduling information for a first maximum number of overlapping uplink transmissions for a serving cell, wherein each uplink transmission of the first maximum number of overlapping uplink transmissions for the serving cell corresponds to an uplink transmission beam pattern of a plurality of uplink transmission beam patterns or a spatial domain transmission filter of a plurality of spatial domain transmission filters;
• receiving, by use of the receiver, a second message that configures uplink power control parameters for each uplink beam pattern of the plurality of uplink transmission beam patterns or each spatial domain transmission filter of the plurality of spatial domain transmission filters;
• receiving, by use of the receiver, scheduling information for a first plurality of overlapping uplink transmissions for the serving cell based on the configuration of the first message, wherein:
• a number of the first plurality of overlapping uplink transmissions is no more than the configured first maximum number of overlapping uplink transmissions;
• the first plurality of overlapping uplink transmissions comprises a first uplink transmission and a second uplink transmission;
• the first uplink transmission corresponds to a first uplink beam pattern of the plurality of uplink transmission beam patterns or a first spatial domain transmission filter of the plurality of spatial domain transmission filters;
• the second uplink transmission corresponds to a second uplink beam pattern of the plurality of uplink transmission beam patterns or a second spatial domain transmission filter of the plurality of spatial domain transmission filters;
• and
• the scheduling information comprises two transmit power control commands that are associated with a same closed-loop power control process;
• determining, by use of a processor, a first transmit power for the first uplink transmission based on a corresponding first set of uplink power control parameters;
• determining, by use of the processor, a second transmit power for the second uplink transmission based on a corresponding second set of uplink power control parameters;
• performing, by use of the processor, the first uplink transmission using the first uplink transmission beam pattern or the first spatial domain transmission filter based on the first transmit power;
• and
• performing, by use of the processor, the second uplink transmission using the second uplink transmission beam pattern or the second spatial domain transmission filter based on the second transmit power.
