METHODS AND APPARATUS SUPPORTING ADAPTIVE DECENTRALIZED TRAFFIC SCHEDULING FOR WIRELESS COMMUNICATIONS
First Claim
1. A method of operating a first wireless terminal in a peer to peer communications system, the method comprising:
- receiving quality of service information corresponding to a communications link from a second wireless terminal to the first wireless terminal;
receiving a transmission request from the second wireless terminal;
determining a request response transmission power level based on received quality of service information; and
transmitting, at the determined power level, a request response in response to the received transmission request.

Abstract
Methods and apparatus relating to scheduling of air link resources, e.g., traffic segments, in wireless communications are described. Various described methods and apparatus are well suited to wireless peer to peer networks in which traffic scheduling is decentralized, e.g. an ad hoc peer to peer network. A first wireless terminal receives a transmission request and quality of service information from a second wireless terminal corresponding to a connection. The first wireless terminal decides not to receiver yield, determines a request response transmission power level as a function of the received quality of service information, and transmits, at the determined power level, a generated request response signal. By controllably adjusting the transmission power level of a request response, transmitter yielding decisions of lower priority links are impacted, since lower priority links measure and use received power level information corresponding to request responses of higher priority links in their transmitter yielding decisions.
