Beacon coding in wireless communications systems

摘要

Systems and methodologies are described that facilitate transmitting beacon symbols of a beacon message such that a sequence of symbols can satisfy a linear constraint over a field where the field elements can be identified with carriers. In this regard, a coding scheme can be applied to a beacon message; the coding scheme can produce a plurality of beacon symbols to transmit on given subcarriers. A receiving device of the beacon symbols can decode a beacon message by receiving less than the total number of symbols in a beacon message and determining the remaining symbol subcarriers based on the linear constraint. Thus, more efficient decoding of beacons is facilitated as well as resolving beacon ambiguity by figuring out which symbols satisfy linear constraints for the symbols, and resolving time and frequency shift by detecting an offset that would result in satisfaction of the linear constraint.

1. A method that facilitates transmitting a beacon message in wireless communications as a plurality of beacon symbols, comprising:
encoding a beacon message as a plurality of beacon symbols such that a number of symbols, less than the total number for the beacon message, is utilized to determine remaining symbols of the beacon message; and transmitting the plurality of beacon symbols less than the total for the beacon message over respective subcarriers at assigned symbol periods; wherein the encoding of the beacon message enables decoding with less than the total number of beacon symbols in the plurality of beacon symbols to obtain more efficient decoding and resolution in wireless communications.
