Abstract
Systems and methodologies are described that facilitate transmitting at least two different types of information in a single signal, whereby the different types of information can be encoded and decoded independently. Thus, changes to one type of information does not affect a second type of information.
Claims22
A method that facilitates receiving information from a base station, comprising:
- receiving a high-energy beacon signal included in a waveform, wherein the waveform is a function of a first value and a second value and the high-energy beacon signal is received on at least one resource that has a resource location based on the first value and the second value;
- determining a bandwidth subset, of a plurality of bandwidth subsets, on which the high-energy beacon signal was received;
- determining a degree of freedom, of a plurality of degrees of freedom, on which the high-energy beacon signal was received;
- interpreting the first value as a first information stream based on the determined degree of freedom;
- and
- interpreting the second value as a second information stream based on the determined bandwidth subset.
