Wireless communication methods and apparatus supporting different types of wireless communciation approaches
First Claim
1. A method of operating a wireless terminal which supports both peer to peer communication and communication via a base station, the method comprising:
- receiving a first signal from a first communications band, the first signal being from a base station;
determining from said first signal, link quality of a first link between said base station and said wireless terminal;
receiving a second signal from a second communications band which is different from said first communications band, said second signal being from a peer wireless terminal;
determining from said second signal, link quality of a second link between said wireless terminal and said peer wireless terminal; and
selecting between said first and second links for a communications session based on the determined quality of said first and second links;
wherein said first signal includes a beacon signal burst transmitted by the base station and said second signal includes a beacon signal burst transmitted by said peer wireless terminal; and
wherein said second signal is transmitted by said peer wireless terminal in a non-infrastructure frequency band in a time interval which is a function of the timing of the beacon signal burst transmitted by the base station.

Abstract
A wireless terminal supports both peer to peer communications and access node based communications. The wireless terminal considers and evaluates communications link alternatives and selects between (i) communication using a peer to peer link and (ii) communications using a link, with a base station serving as an access node, Received signals corresponding to each of the link alternatives are used in performing link quality determinations. In one example, a received user beacon signal from a peer wireless terminal is the received signal used for the peer to peer link evaluation and a: base station beacon signal is the received signal used for the access node link evaluation. A link is selected as a function of quality determination, predicted data throughput, link maintenance energy requirements, and/or least cost routing determination information.
