Abstract
A wireless communications device supporting peer-to-peer communications acquires peer-to-peer communications resources for an extended period of time. In some embodiments, a base station assigns the resources to the device, while in other embodiments, the device reserves, e.g., self-assigns peer-to-peer communications resources for an extended period of time. The wireless communications device decides that it will not be using an acquired peer-to-peer communications resources, e.g., a particular acquired peer-to-peer traffic segment. The wireless communications device transmits a resource availability indicator indicating that it will not be using the particular peer-to-peer communications resource. Another wireless communications device, which detects the resource availability indicator, may use the peer-to-peer communications resource which is not be used by the device to which it is assigned.
