Claim Text:
1. A method of generating a frequency division multiplexed signal at a communications device for transmission in a wireless communication system, comprising: obtaining, by the communications device, one or more sets of M complex data symbols for transmission using a set of M tones allocated to the communications device for a dwell period comprising a plurality of symbol periods, wherein the set of M tones is a subset of tones in an available bandwidth; generating, by the communications device, one or more sets of M signal coefficients based at least in part on the one or more sets of M complex data symbols, wherein the one or more sets of M signal coefficients are mapped to the set of M tones for one or more symbol periods of the plurality of symbol periods of the dwell period, wherein generating the one or more sets of M signal coefficients comprises generating each of the one or more sets of M signal coefficients by performing a summation of a product of a set of M complex data symbols of the one or more sets of M complex data symbols and M complex sinusoids corresponding to the set of M tones; mapping, by the communications device, at least one set of M training symbols to the set of M tones for at least one symbol period of the plurality of symbol periods of the dwell period; processing, for each symbol period of the plurality of symbol periods of the dwell period, a corresponding set of M mapped symbols of the one or more sets of M signal coefficients and the at least one set of M training symbols to obtain the frequency division multiplexed signal for the each symbol period of the plurality of symbol periods of the dwell period; and transmitting, by the communications device, the frequency division multiplexed signal in the wireless communication system.
