Power decision pilot for a wireless communication system
First Claim
1. A method for wireless communication, comprising:
- receiving at a first station a message sent by a second station to request reduction of interference on at least one resource;
determining a first transmit power level to use for the at least one resource by the first station in response to receiving the message; and
sending a pilot from the first station at a second transmit power level determined based on the first transmit power level.

Abstract
Techniques for transmitting data with short-term interference mitigation in a wireless communication system are described. In one design, a first station (e.g., a base station or a terminal) may receive a message sent by a second station to request reduction of interference on at least one resource. In response to receiving the message, the first station may determine a first transmit power level to use for the at least one resource based on one or more factors such as a priority metric sent in the message, the buffer size at the first station, etc. The first station may send a power decision pilot on the at least one resource at a second transmit power level determined based on the first transmit power level.
