Abstract:
Methods and apparatus related to broadcasting data in a peer to peer wireless communications network are described. A timing structure is utilized employing slots of a first type which support broadcast traffic transmissions and unicast traffic transmissions and slots of a second type which support unicast traffic transmission but do not support broadcast traffic transmissions. In various embodiments, traffic air link resource scheduling is performed in a decentralized manner on a slot by slot basis. In some such embodiments, a wireless device prior to transmitting a broadcast data traffic signal, transmits a broadcast transmission request signal, sometimes alternatively referred to as a broadcast indicator signal; and a wireless device prior to transmitting a peer to peer unicast signal, transmits a peer to peer traffic transmission request signal. In various embodiments, for slots of the first type, broadcast transmission requests have priority over peer to peer unicast transmission requests.
