Abstract:
Wireless terminal operation is coordinated to be responsive to dynamic communications frequency spectrum reallocation between infrastructure based communications usage and peer to peer communications usage. Methods and apparatus in which mobile nodes switch between cellular and peer to peer communication modes of operation are described. Broadcast signals, e.g., beacon signals, are monitored and detected by the mobile node to ascertain a current spectrum usage designation, and the mobile node switches operational modes in response to detected changes in the broadcast signals.
