Abstract

A method of operating a wireless device includes communicating in one of peer-to-peer data resources or non peer-to-peer resources. The peer-to-peer data resources include a first set of peer-to-peer resources with a first bandwidth and a second set of peer-to-peer resources with a second bandwidth greater than the first bandwidth. The first set of peer-to-peer resources is parallel in time with the non peer-to-peer resources. In addition, the method includes estimating a signal quality for a data transmission on the peer-to-peer data resources. Furthermore, the method includes determining whether to send the data transmission in one of the first set of peer-to-peer resources or the second set of peer-to-peer resources based on the estimated signal quality.
