Methods and apparatus for providing transmit power control for devices engaged in D2D communications

摘要

A method, an apparatus, and a computer program product for wireless communication are provided for using power control to reduce potential interference to a macro eNB by a UE engaged in D2D communications. An eNB may be operable to generate a fractional power control parameter based on a macro eNB power saturation value and broadcast the factional power control parameter. A UE may be equipped to receive the factional power control parameter and determine whether the fractional power control parameter plus a path loss value between the UE and the macro eNB is less than a maximum power used for the D2D communications. The UE may reduce the maximum transmit power used for D2D communications when the fractional power control parameter plus a path loss value between the UE and the macro eNB is less than a maximum power used for the D2D communications.

1. A method of wireless communications, comprising:
generating a fractional power control parameter based on a macro evolved nodeB (eNB) power saturation value; and broadcasting the fractional power control parameter to prompt one or more user equipments (UEs) engaged in device to device (D2D) communications to maintain a transmit power level below a power level based on the fractional power control parameter.
