Support for wide area networks and local area peer-to-peer networks
First Claim
1. A method that facilitates communicating via a shared spectrum, comprising:
- identifying a wide area network from a received signal;
employing a first set of parameters for said wide area network in a wireless spectrum;
determining, based upon the identity of the wide area network, local area network parameters to be employed in wireless spectrum used by said identified wide area network, said local area network parameters being a second set of parameters, said second set of parameters including at least one of tone spacing or cyclic prefix duration, at least one parameter in said second set of parameters differing from a parameter in the first set from which said at least one parameter is generated; and
employing the second set of parameters for peer to peer communications in a local area peer-to-peer network in the same wireless spectrum used by said wide area network.

Abstract
Systems and methodologies are described that facilitate sharing bandwidth between a wide area network and a local area peer-to-peer network. The peer-to-peer network may use an air interface technology that is similar to distinct from an air interface technology used in the wide area network. Moreover, the wide area network and the local area peer-to-peer network may utilize distinct sets of parameters. For example, if the wide area network and the peer-to-peer network use OFDM-based air interface technologies, parameters such as tone spacing, symbol time, cyclic prefix, and the like of the two networks may vary. Further, peer-to-peer parameters may be a function of parameters for the wide area network.
