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： Various embodiments relate to wireless communications, and more particularly, to methods and apparatus for authorizing use of spectrum, e.g., through the issuance of spectrum access keys, and/or preventing or discouraging the unauthorized use of licensed spectrum. Peer to peer wireless communications between authorized users of licensed spectrum may involve scrambling/descrambling of information communicated between authorized devices. In some embodiments air interface timing and/or other information received from a second device, e.g., a beacon or GPS transmitter, is incorporated into a computation of a pseudo-random bit sequence which is also computed based on a spectrum access key communicated to authorized spectrum users. In some embodiments authorized peer to peer devices scramble communicated information based on the generated pseudo random bit sequence thereby preventing or discouraging communication with devices which are not authorized to use the spectrum and lack a spectrum access key used to generate the pseudo random bit sequence.

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.

摘要： Methods and apparatus related to communicating advertisements and/or service announcements to devices in a communications system are described. In various embodiments mobile devices are used as mobile advertisement transmission platforms. Advertisements may be downloaded to the wireless communications device along with transmission constraints. Transmission of an advertisement is made when a transmission constraint, e.g., target audience constraint is satisfied. The wireless terminal may change its transmission frequency, coding rate and/or other transmission characteristics to satisfy a transmission constraint and/or optimize revenue. The mobile device reports advertisements transmissions to a network device, e.g., advertisement server and the owner of the device is compensated for the transmissions. Transmission constraints may involve a number of devices to be reached, the type of devices to be reached, and/or other constraints relating to the demographics of device users. Information may be obtained from peer discovery signals and used to determine if a constraint is satisfied.

摘要： Wireless communications devices, e.g., peer to peer mobile wireless terminals in and ad-hoc peer to peer communications network, support multiple modes of peer discovery operation. In different peer discovery transmit modes peer discovery information is transmitted at different rates. In different peer discovery receive modes peer discovery information is monitored at different rates. Performing peer discovery operations at a higher rate has the benefit of reducing discovery latency at the cost of utilizing more communications resources and expending more power. A communications device dynamically changes its mode in response to changing conditions and/or needs. Transitions between modes are in response to a determined change condition trigger occurrence. Various change condition triggers include, e.g., a user event, an application event, information received over the air interface, information derived from information received over the air interface and/or temporal information.

摘要： Methods and apparatus related to peer/network/service discovery in a mobile wireless system, e.g., an ad hoc peer-to-peer network are described. Transmission of discovery information, e.g., upper layer discovery information, is divided into a number of portions to be transmitted separately over time. Transmission of the individual portions is structured so as to enable flexibility in the frequency of the peer discovery transmissions as well as the monitoring of such transmissions. Various embodiments facilitate rapid discovery and/or secure discovery, e.g., selective discovery by trusted peers.

Various embodiments facilitate rapid discovery and/or secure discovery, e.g., selective discovery by trusted peers. The structuring enables proxying of some transmissions by a third party, e.g., an assist node. The assist node receives discovery information portions being communicated at a first rate and retransmits the received discovery information portions at a second rate which is higher than the first rate.
