METHOD FOR CONTROLLING TRANSMIT POWER OF A MOBILE STATION

摘要

Method and apparatus for controlling a transmit power of a mobile station are disclosed. Mobile stations in direct communication on a cross link (XL) receive control parameters from a base station. A first mobile station (a receiving mobile station) may calculate a correction parameter for power offset for transmissions from a second mobile station (a transmitting mobile station) to the first mobile station, and send it to the second mobile station. The correction parameter may be generated within the maximum and minimum limits. The second mobile station may calculate a transmit power level for a transmission to the first mobile station based on the correction parameter, measurements on resources allocated for cross links for mobile station-to-mobile station direct communications, an interference measurement received from the first mobile station, and a path loss to the first mobile station.

主权项

1. A method for use in a wireless transmit receive unit (WTRU), the method comprising:
receiving, from a base station associated with WTRU to WTRU direct communication, power control configuration information for use in WTRU to WTRU direct communication; wherein the power control configuration information includes power control configuration information for an uplink channel from the WTRU to the base station and for a data channel for WTRU to WTRU direct communication and for a control channel for WTRU to WTRU direct communication; transmitting over the uplink channel to the base station at a power level based on a pathloss value added to a first value received in the power control configuration information; transmitting over the data channel, selectively using a power level based on a pathloss value added to a second value received in the power control configuration information or using a power level not based on the pathloss value; and transmitting over the control channel based on the power control configuration information for the control channel.
