Abstract
Official abstract text for this publication.
A method and apparatus for power control for distributed wireless communication is disclosed including one or more power control loops associated with a wireless transmit/receive unit (WTRU). Each power control loop may include open loop power control or closed loop power control. A multi-phase power control method is also disclosed with each phase representing a different time interval and a WTRU sends transmissions at different power levels to different set of node-Bs or relay stations during different phases to optimize communications.
First claim
Opening claim text (preview).
What is claimed: 1 . A method implemented by a wireless transmit receive unit (WTRU), the method comprising: receiving a control message, the control message including a transmit power command (TPC) and an indication of a first multi-antenna configuration of a plurality of multi-antenna configurations for sending an uplink channel transmission; determining a first power control loop, of a plurality of power control loops, for the first multi-antenna configuration of the plurality of multi-antenna configurations; and sending the uplink channel transmission at an uplink transmission power level of the first power control loop, wherein timing information is associated wih the uplink transmission power level, and wherein the uplink transmission power level is further derived from a pathloss estimate determined for the uplink channel transmission using the first multi-antenna configuration. 2 . The method of claim 1 , wherein the pathloss estimate relates to a link between the WTRU and one or more base stations. 3 . The method of claim 1 , wherein the control message is received from a base station. 4 . A wireless transmit receive unit (WTRU), the WTRU comprising: a processor operatively coupled to a transceiver, the processor and transceiver configured to receive a control message, the control message including a transmit power command (TPC) and an indication of a first multi-antenna configuration of a plurality of multi-antenna configurations for sending an uplink channel transmission; the processor and transceiver configured to determine a first power control loop, of a plurality of power control loops, for each of a plurality of multi-antenna configurations; and the processor and transceiver configured to send the uplink channel transmission at an uplink transmission power level of the first power control loop wherein timing information is associated with the uplink transmission power level, and wherein the uplink transmission power level is further derived from a pathloss estimate determined for the uplink channel transmission using the first multi-antenna configuration. 5 . The WTRU of claim 4 , wherein the pathloss estimate relates to a link between the WTRU and one or more base stations. 6 . The WTRU of claim 4 , wherein the control message is received from a base station.
