Abstract:
Methods and apparatus related to broadcasting data and interference management in a peer to peer wireless communications network are described. Scheduling of traffic air link resources is performed on a slot by slot basis in a decentralized manner. Wireless devices intending to broadcast traffic signals transmit broadcast request signals, sometimes alternatively referred to as broadcast indicator signals. A priority level is associated with each of the broadcast request signals. A receiver device intending to receive broadcast signals detects the broadcast request signals and makes an interference determination as to whether the higher priority broadcast traffic signal can be successfully recovered in the presence of lower priority broadcast traffic signals. If the determination is that the expected interference from the lower priority broadcast traffic is unacceptable, the receiver device generates and transmits an interference control signal communicating to the lower priority device a command or request not to broadcast.
