System and Method for Closed-loop Uplink Power Control

A method, comprising:

• establishing communication with a network via a plurality of base stations, wherein said communication comprises closed-loop uplink power control and unordered scheduling;
• receiving, from the network, control information including:
• a first grant scheduling a first uplink transmission to a first base station of the plurality of base stations;
• a second grant scheduling a second uplink transmission to a second base station of the plurality of base stations;
• and
• a plurality of transmit power control commands;
• determining a first subset of the plurality of transmit power control commands to apply to the first uplink transmission;
• determining a second subset of the plurality of transmit power control commands to apply to the second uplink transmission, wherein the second subset of the plurality of transmit power control commands is different from the first subset of the plurality of transmit power control commands;
• determining, based on the first subset of the plurality of transmit power control commands, a first transmit power for the first uplink transmission;
• determining, based on the second subset of the plurality of transmit power control commands, a second transmit power for the second uplink transmission;
• and
• after the determination of the first subset of the plurality of transmit power control commands and the determination of the subset of the plurality of transmit power control commands:
• transmitting, to the first base station, the first uplink transmission using the first transmit power;
• and
• transmitting, to the second base station, the second uplink transmission using the second transmit power.

An apparatus, comprising:

• a processor configured to cause a user equipment to:
• establish communication with a network via a plurality of base stations, wherein said communication comprises closed-loop uplink power control and unordered scheduling;
• receive, from the network, control information including:
• a first grant scheduling a first uplink transmission to a first base station of the plurality of base stations;
• a second grant scheduling a second uplink transmission to a second base station of the plurality of base stations;
• and
• a plurality of transmit power control commands;
• determine a first subset of the plurality of transmit power control commands to apply to the first uplink transmission;
• determine a second subset of the plurality of transmit power control commands to apply to the second uplink transmission, wherein the second subset of the plurality of transmit power control commands is different from the first subset of the plurality of transmit power control commands;
• determine, based on the first subset of the plurality of transmit power control commands, a first transmit power for the first uplink transmission;
• determine, based on the second subset of the plurality of transmit power control commands, a second transmit power for the second uplink transmission;
• and
• after the determination of the first subset of the plurality of transmit power control commands and the determination of the subset of the plurality of transmit power control commands:
• transmit, to the first base station, the first uplink transmission using the first transmit power;
• and
• transmit, to the second base station, the second uplink transmission using the second transmit power.

A method, comprising:

• establishing communication with a user equipment device (UE) via a first transmit/receive point (TRP) and a second TRP of a cellular network;
• scheduling a first uplink communication from the UE to the first TRP;
• determining a first selected transmission power level for the first uplink communication;
• scheduling a second uplink communication from the UE to the second TRP;
• determining a second selected transmission power level for the second uplink communication;
• configuring a series of transmission power control commands for at least one closed-loop power control process to indicate the first selected transmission power level and the second selected transmission power level;
• and
• causing the first TRP and/or the second TRP to transmit the series of transmission power control commands.
