Abstract:
1. A method for operating a first wireless device communicating with a second wireless device within a wireless peer-to-peer communication network, the wireless peer-to-peer communication network sharing a frequency spectrum with a wireless wide area network, comprising: partitioning a time frequency structure into a plurality of subsets of tone-symbols, the time frequency structure including a plurality of orthogonal frequency-division multiplexing (OFDM) symbols and each of the plurality of OFDM symbols including a plurality of tones, a tone-symbol being one tone in one of the plurality of OFDM symbols; selecting a first plurality of tone-symbols from the tone-symbols in said plurality of OFDM symbols, said first plurality of tone-symbols partially overlapping tone-symbols used by said wide area network for wide area network signal transmission during a first time period and including at least one tone-symbol which is not used by said wide area network for wide area network signal transmission during said first time period; and transmitting a peer-to-peer signal to the second device using the first plurality of tone-symbols during said first time period.
