Wireless communications methods and apparatus are described. A communicat ions apparatus, e.g., a base station, measures interference information, e.g ., other sector interference information. The communications apparatus gener ates 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 superfra me strucuture, including the preamble and a plurality of frames, at least so me of the frames used to convey traffic data. The communications apparatus t ransmits the preamble, thus broadcasting the interference information to acc ess terminals in the vicinity. An access terminal receives the preamble incl uding a plurality of pilot signals, at least one of the pilot signals includ ing interference information. The access terminal recovers the interference information from the received preamble and controls signal transmission base d on the recovered interference information. |
