Serving sector directed power control
First Claim
1. A method for facilitating serving sector control of terminal transmission power comprising:
- analyzing power related data associated with a terminal supported by a serving sector;
obtaining non-serving sector interference information through backhaul signaling; and
transmitting power control information, based at least in part upon the analysis, to the terminal supported by the serving sector, wherein transmission power of the terminal is a function of the power control information, the power control information is a function of the non-serving sector interference information, and the power control information can override terminal-based transmission power computation.

Abstract
Systems and methodologies are described that facilitate serving sector directed transmit power control in a wireless communication environment. Under certain conditions, an access point can have better data with which to determine appropriate power levels than an individual terminal. Accordingly, an access point can transmit power control information to one or more terminals supported by the access point overriding normal power determination procedures. In particular, power control information can be included within an assignment message that designates resources (e.g., frequency, time) assigned to a terminal. Power control information can be based upon SNR, quality of service requirements, interference information, any other relevant information or any combination thereof.
