Abstract
A base station apparatus is provided. The base station apparatus includes an orthogonal frequency division multiplexed (OFDM) encoder and a time division multiplexer. The OFDM encoder is configured to encode a plurality of data streams into a corresponding plurality of OFDM tones, where one of the corresponding plurality of OFDM tones includes an OFDM preamble tone that indicates a mapping of remaining OFDM tones within the plurality of OFDM tones to one or more of a plurality of mobile stations, and indicates at least one of the plurality of tones addressed to a particular mobile device, and wherein the preamble tone is not fixed to the selected particular mobile device through communication. multiplexes a plurality of streams over a forward link channel for receipt by the plurality of mobile stations, where the corresponding plurality of OFDM tones are encoded as one of the plurality of streams.
