Uplink power control for distributed wireless communication

A method for use in a wireless transmit/receive unit (WTRU), comprising:

• utilizing, by the WTRU, a first closed loop power control factor for a first set of transmission time intervals (TTIs) and a second closed loop power control factor for a second set of TTIs, wherein the first closed loop power control factor is determined by accumulating first power commands and the second closed loop power control factor is derived by combining second power commands;
• transmitting, by the WTRU, at a transmission power level based on the first closed loop power control factor in the first set of TTIs;
• and
• transmitting, by the WTRU, at a transmission power level based on the second closed loop power control factor in the second set of TTIs.

An evolved nodeB (eNodeB), comprising:

• a processor configured to utilize, for a wireless transmit/receive unit (WTRU), a first closed power control loop for a first set of transmission time intervals (TTIs) and a second closed power control loop for a second set of TTIs;
• a transmitter configured to transmit, to the WTRU, first power commands for the first closed power control loop and second power commands for the second closed power control loop;
• and
• a receiver configured to receive, from the WTRU, a transmission in the first set of TTIs at a transmission power level based on the first closed power control loop, and to receive, from the WTRU, a transmission in the second set of TTIs at a transmission power level based on the second closed power control loop.
