METHODS AND APPARATUS FOR CONTROLLING RESOURCE USE IN A WIRELESS COMMUNICATIONS SYSTEM
First Claim
1. A method of operating a first communications device, the method comprising:
- receiving first and second signals from second and third communications devices, respectively, on a first shared communications resource being used by both said second and third communications devices;
determining that signal quality of the first and second signals is insufficient for reliable decoding; and
transmitting an interference signal on said first shared communications resource.

Abstract
Methods and apparatus for detecting, controlling and/or mitigating interference are described. Various embodiments are well suited to wireless communications systems in which shared communications resources are used, e.g., in a peer to peer communications systems lacking centralized control. In some embodiments, a communications device receives signals on shared communications resource, evaluates its capability to decode a received signal, and conditionally transmits an interference signal, e.g., on the shared communications resource. The interference signal is intended to cause a device transmitting on the shared communications resource to switch to a different communications resource, e.g., in response to the interference signal, so that its transmitted signal can be successfully decoded. In at least one embodiment, the shared communications resource is a peer discovery air link resource associated with a peer discovery resource identifier.
