摘要： Methods and apparatus supporting enhanced discovery operations in peer to peer networks are described. Peer discovery, based on direct peer to peer discovery between two mobile nodes can be somewhat limited, e.g., due to power limitations, processing power, and/or channel conditions. An access point, e.g., base station, monitors for and receives peer discovery signals conveying a set of identifiers from a wireless communications device. The access point retransmits at least one identifier in the set in a wireless peer to peer communications channel. Thus the access point effectively extends the peer discovery range for wireless communications devices utilizing the peer to peer network. Wireless communications devices can monitor for and recover the rebroadcast peer discovery signals from access points. Thus, via access point signaling a wireless communications device can be made situationally aware of other devices of interest which would be otherwise outside its discovery detection range.

摘要： Methods and apparatus well suited for efficiently communicating small amounts of information relatively frequently in a wireless communications system are described. An uplink timing frequency structure for an access point includes a set of dedicated uplink communications resources, e.g., expression advertisement interval air link resources. Different ones of the set of dedicated uplink communications resources correspond to different individual wireless communications devices currently registered with the access point. In the downlink timing frequency structure for the access point there are dedicated downlink broadcast communications resources, e.g., expression broadcast interval air link resources and neighbor expression broadcast interval air link resources. Information received on dedicated uplink air link resources is echoed back or selectively echoed back on the dedicated downlink air link resources. Wireless communications devices monitor downlink dedicated air link resources to recover expression information being communicated by other wireless communications devices in its local vicinity.

摘要： A first wireless communications device includes a wide area network (WAN) interface and a peer to peer interface. The first device discovers the presence of a second wireless communications device via a peer discovery signal, received via its peer to peer interface. The second device has been transmitting, e.g., periodically, certain information, e.g., its location and/or shopping preferences, to a node within the WAN. The detected first signal triggers an application alert in the first device. The first device recovers past information about the second device through a second signal received via its WAN interface. The first device uses information communicated in the first signal, e.g., device identifier information, and information communicated in the second signal, e.g., past location and/or shopping information, to generate a targeted message for the second device. The first device communicates the targeted message via its peer to peer interface in a peer to peer traffic channel.

摘要： Methods and apparatus for supporting multiple modes of communication operation, e.g., with different parameters and/or frequency bands being used in the different modes of operation are described. One or more adjustments are made based on a signal or signals received in a first frequency band from a second communications device, e.g., an access router with reliable timing. The communications device selects between and operates in either the first frequency band, e.g., a WAN frequency band, or in a second frequency band, e.g., a LAN frequency band. The WAN and LAN frequency bands may be non-overlapping. One or more parameters used in the second frequency band have a predetermined relationship to one or more parameters used for communications in the first frequency band making the adjustment based on the signal received in the first frequency band relevant and useful to support communications in the second frequency band.

摘要： One feature provides for establishing an ad hoc peer-to-peer network over an existing channel allocation for another network. To mitigate interference between multiple peer-to-peer devices, a plurality of receiver chains in a receiver device may be configured with beamforming coefficients so as to focus reception in the direction of an intended signal from a transmitter device while minimizing reception from other directions. Similarly, the receiver device may also use a plurality of antennas and a transmitter chain to beamform in the direction of the transmitter device, thereby focusing its transmission toward the transmitter device. The receiver device may also notify nearby devices that it is employing a plurality of receive antennas. This information can be used by the nearby devices to more intelligently perform transmitter yielding. By utilizing beamforming information to make the transmitter and/or receiver yielding decision, better interference mitigation may be achieved.
摘要翻译：一个特征提供了通过用于另一网络的现有信道分配来建立自组织对等网络。为了减轻多个对等设备之间的干扰，接收机设备中的多个接收器链可以被配置成具有波束成形系数，以便在来自发射机设备的预期信号的方向上聚焦接收，同时最小化从其他方向的接收。类似地，接收机设备还可以使用多个天线和发射机链在发射机设备的方向上波束成形，从而将其传输集中到发射机设备。接收机设备还可以通知附近的设备它正在采用多个接收天线。该信息可被附近的设备用于更智能地执行发射机的收发。通过利用波束成形信息来使发射机和/或接收机产生决定，可以实现更好的干扰减轻。

摘要： Methods and apparatus related to peer to peer communication networks are described. A peer to peer timing structure is implemented which includes recurring peer discovery intervals and traffic intervals. Some embodiments further include recurring paging intervals for peer to peer pages. A wireless communications device, supporting peer to peer communications and storing information defining the timing structure, determines a time reference point, facilitating a coarse level of synchronization with respect to the timing structure. The time reference point is determined based on a broadcast signal received from a communications device, e.g., a satellite, base station, or beacon signal transmitter. Multiple peer to peer wireless communications devices in a local vicinity thus obtain the same basic understanding as to the current relative point in time with respect to a common recurring peer to peer timing structure. Peer to peer timing synchronization is further refined based on received signals communicated between peers.

摘要： Methods and apparatus well suited for supporting communications over different ranges in, for example, a peer to peer wireless communications system, are described. In the peer to peer network at least some of the types of signals, e.g., peer discovery signals and/or paging signals, are transmitted with no closed loop power control. An exemplary peer to peer timing structure includes air link resources allocated for a particular type of signaling in which the resources are segmented into multiple blocks which do not overlap in time, different ones of the multiple blocks being associated with different ranges. The characteristics of the basic transmission units of the multiple blocks based on range are different, e.g., tone size and symbol width are different. A wireless communications device implements the peer to peer timing structure and uses resources from different range based blocks at different times. Data traffic transmission units may be the same regardless of the range.

摘要： Methods and apparatus for using different frequency bands are described. In some embodiments a first frequency band which is a licensed spectrum frequency band is used for peer discovery, device authentication, session establishment between peer devices and/or supporting an ongoing communications through control signaling. When available, a second frequency band, e.g., an unlicensed public frequency band is used for communicating data while the communications session is maintained using one or more control signals communicated in the first frequency band. Data and control signaling may be performed on a time division basis during a time period in which data is communicated.

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： An improved mechanism is provided that facilitates transmission of small packets within an ad hoc peer-to-peer network. A small packet is identified to a receiver within a control channel so that its lower power can be considered in an interference management protocol implemented among local peer devices. In a traffic slot, a transmitter voluntarily backs down on the transmitter power as a smaller packet will require much lower signal-to-noise ratio. This will improve the signal energy per bit per noise power density for the transmission as well as minimize the interference caused to other wireless communications happening in the same spectrum.
