Abstract
Wireless communications methods and apparatus are described. A communications apparatus, e.g., a base station, measures interference information, e.g., other sector interference information. The communications apparatus generates a preamble which includes a plurality of pilot symbols and at least one of the pilot symbols includes interference information. In some embodiments, the preamble is part of a superframe structure, e.g., a recurring superframe structure, including the preamble and a plurality of frames, at least some of the frames used to convey traffic data. The communications apparatus transmits the preamble, thus broadcasting the interference information to access terminals in the vicinity. An access terminal receives the preamble including a plurality of pilot signals, at least one of the pilot signals including interference information. The access terminal recovers the interference information from the received preamble and controls signal transmission based on the recovered interference information.
