Claim Text:
1. A method for use in a wireless communication system that supports orthogonal frequency division multiplexing (OFDM) of transmissions over a plurality of subcarriers having orthogonal frequencies, comprising: allocating, at a network entity, at least one of a plurality of sub-bands for communication with at least one access terminal, each of the plurality of sub-bands comprising at least one of the plurality of subcarriers and being associated with a corresponding one of a plurality of pseudo-random sequences, wherein each pseudo-random sequence comprises at least one symbol; generating a signal by combining symbols in the plurality of pseudo-random sequences with a plurality of control values that indicate whether a corresponding sub-band is allocated to said at least one access terminal; and transmitting the signal over an air interface, wherein transmitting the signal comprises transmitting at least one of a plurality of orthogonal pseudo-random sequences or pseudo-random sequences that are substantially uncorrelated.
