摘要： 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.

摘要： Methods and apparatus for wireless communications in regional networks, e.g., ad hoc peer to peer networks, are described. Wireless communications devices transmit and monitor for presence indicator signals broadcast from other peer communications devices in its local vicinity. A wireless communications device maintains a list of discovered devices in its vicinity. A first wireless communications device transmits a paging signal directly over an airlink to a second communications device, which is on its list and to which it desires to send data units, e.g., user data in a peer to peer traffic segment. In response to a received paging response signal from the second device, the first device transmits data units, intended for the second device, to a third device, which acts as an intermediary node. The power level for the data unit signal is controlled to be lower than the power level used for the paging signal. FIG. 4

摘要： 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.

摘要： Methods and apparatus for communicating information, e.g., queries and query responses, in a peer to peer communications network are described. Queries include, e.g., queries for a product, service, activity or activity partner. In some embodiments, a query channel is implemented and utilized. The implemented query channel structure is such that multiple query responses may be communicated corresponding to a single transmitted query. Various embodiments employ randomization in transmission segment selection by an individual communications device within a transmission block to decrease the likelihood of collisions. A communication device's access to the query channel is determined by the communications device itself. A communications device's decision as to whether or not to transmit and/or re-transmit a query is based on one or more of: its query transmission statistics, historical query channel loading information, and priority level information corresponding to the communications device.

摘要： Methods and apparatus for wireless communications in networks, e.g., regional ad hoc peer to peer networks, are described. A communications node, e.g., a third node monitors for wireless communications between other peer communication nodes, e.g., a first node and a second node, in its local vicinity. The third node determines from the monitored wireless communication an indication of link quality corresponding to a communication link between the communication nodes which are communicating or seeking to establish a communications link. The third node generates an estimate of a link quality for a communications link between itself and the first node. Based on the indication of link quality and generated estimate of link quality, the third node decides whether or not to send a signal indicating availability to relay communication between the first and second nodes. The third node, when acting as an intermediary node after indicating its availability to so act, may receive traffic data e.g., user data communicated in a peer to peer traffic segment, from the first node. The third node communicates the received traffic data to the second node by transmitting the traffic data.
