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 related to a peer to peer wireless communications system (102,104) supporting secure advertisement of identification and/or discovery information (132) e.g., upper layer discovery information, are described. Air interface timing and/or other information received from a third device (112), e.g., a beacon or GPS transmitter is incorporated in the computation of identification/discovery information (207) which is communicated from a first device to a second device. The second device stores some identification/discovery credentials corresponding to the first device (212), which have been communicated out of band from the first device to the second device (130). Upon receipt of a identifier from a first device, the second device determines if the stored information corresponds to the device that transmitted the identifier (218). Various embodiments facilitate secure advertisement of identification and/or discovery information and discovery, e.g., selective discovery by trusted peers.

摘要： Methods and apparatus for allocating traffic contention resource units in a wireless communications system in which decisions are made in a distributed manner are described. A wireless communications device, corresponding to a link, self allocates resource units for traffic contention. Decisions regarding initially acquiring resources, relinquishing acquired resources, and/or acquiring additional resources for traffic contention are based on detected levels of network congestion and/or detected changes in network congestion. A wireless communications device detects a level of network congestion and determines a number of resource units to acquire for traffic contention based on the detected level of network congestion.

摘要： Aspects describe different multiple antenna techniques that can be utilized in a peer-to-peer network based on a network congestion level. A MIMO scheme where a transmitter sends to a receiver multiple spatial streams at substantially the same time in the same traffic segment can be utilized when network congestion level is low. A receiver beam forming scheme where transmitter sends a single stream in a traffic segment and receiver uses multiple receive antennas to maximize signal to noise ratio can be utilized when network congestion level is high. The connection pair (transmitter and receiver) occupy more control resources in the MIMO scheme than the receiver beam forming scheme. The decision related to which technique to utilize can be made at about the same time as a communication is initiated. Further, if network conditions change during a communication, the antenna technique that is utilized can be switched to a different technique during the communication exchange.

摘要： Methods and apparatus related to scheduling traffic slots in a wireless communications system, e.g., an ad hoc peer to peer communications network are described. An implemented timing structure includes multiple traffic transmission slots and multiple request blocks with different priorities corresponding to a traffic transmission slot. A wireless terminal determines its own block priority level. If a wireless terminal's determined block priority level is the highest block priority level the wireless terminal is allowed to transmit a traffic transmission request in the highest traffic transmission request block; otherwise, the wireless terminal is restricted from transmitting a traffic transmission request in the highest priority request block. A wireless terminal monitors for request and/or request response activity corresponding to other connections high priority block signaling, and uses the collected information to determine its own block priority.

摘要： A communication system receives attributes associated with access terminals within a cell and groups them in accordance with similarities between the received attributes. Resource assignment messages customized to their respective attributes are transmitted to the groups, thereby ensuring that all groups receive these messages. These groups are formed dynamically as the attributes of the access terminals vary when they traverse through a cell.

摘要： Various schemes for reducing effects of interference within communication systems are disclosed. A transmitter transmits a signal in a first time interval and a scrambled version of the signal in a second time interval, which does not overlap with the first time interval. A receiver receives a composite signal including a signal transmitted from the desired transmitter as well as signals from interferers in the first or the second time interval. The receiver determines a dominant interferer and obtains knowledge of signal scrambling done by the interferer as well as the desired transmitter by sensing an identification associated with the interferer or the desired transmitter. This knowledge is employed to determine coefficients for combining the received composite signals received in the first and the second time interval in order to recover the desired signal in a manner that maximizes the SNR associated with the desired signal or completely cancels the dominant interference.

摘要： Methods and apparatus related to the communication of traffic in peer to peer communications are described. A peer to peer communications system includes traffic slots, and for a pair of devices having a connection a first transmission request resource and a second transmission request resource are associated with a traffic transmission interval of the traffic slot, the first request resource preceding the second request resource. A first device of the pair uses the first request resource to signal its intention to transmit traffic in the transmission traffic interval of the slot to the second device of the pair. The second device uses the second request resource to signal its intention to transmit traffic in the transmission traffic interval of the slot to the first device. An implemented protocol determines whether a request in the second resource can override a request in the first resource.
