摘要： Methods and apparatus supporting peer to peer communications are discussed. A base station, serving as an access node for wireless terminals also communicates information supporting peer to peer communications. A base station transmits a beacon signal conveying information about a peer to peer frequency band and also receives user data from a plurality of wireless terminals, using the base station as a current point of network attachment. In some embodiments, the beacon signal is transmitted into the same frequency band being used for access node based communications and identifies a different frequency band which is to be used as a peer to peer frequency band. Alternatively, or in addition, in support of peer to peer communications, a beacon signal transmission apparatus, a free standing device which doesn't transmit user data, transmits a sequence of beacon signal bursts, each beacon signal burst including at least one high power beacon symbol.

摘要： Wireless terminals receive beacon signals from other communication devices and make transmission decisions based on priority information communicated by the beacon signals. Priority information communicated in a beacon signal includes, e.g., one of device priority, user priority and session priority. A wireless terminal compares priority information recovered from received beacon signals with its own current level of priority. A transmission decision based on received priority information includes deciding not to transmit user data when received priority information indicates a higher priority than its own priority level. Another transmission decision based on received priority information includes deciding to transmit user data when the received priority information indicates a lower priority than its own priority level. Other exemplary transmission decisions, performed as a function of priority information from beacon signals, include deciding to perform a transmission power level adjustment and deciding to terminate an ongoing communications session.

摘要： The claimed subject matter relates to providing uplink data rate option information in an uplink traffic channel segment. A wireless terminal may indicate a data rate option being used for the segment via an energy pattern applied to the tone-symbols of the segment. To indicate a first data rate option, additional energy may be applied to a first set of tone-symbols of the segment. To indicate a second rate option, additional energy may be applied to a second set of tone-symbols of the segment, the second set being different from the first set. According to some aspects, each implemented energy pattern may be represented by a pattern, which has a slope (e.g., in a logical, pre-hopped representation of the channel segment), where some of the patterns have positive slope and some of the patterns have negative slope. The use of positive and negative slopes facilitates the representation of more data rate options than would be possible if only one type of slope (positive or negative) for the energy pattern were utilized.

摘要： Methods and apparatus related to assignment in a wireless communications system are described. A mobile is assigned an identifier and a mask value, e.g., as part of a state transition message. The mobile uses the assigned identifier and/or the assigned mask value in determining whether assignments included in assignment messages, e.g., traffic channel assignment messages, are directed to the wireless terminal. Predetermined associations between assignment slots, assigned segments, and/or mask values are utilized to limit control signaling overhead. Different groups of segments are available for assignment to different wireless terminals as a function of mask values. Different types of assignment messages use different amounts of information bits to convey the assignment. Some types of assignments use a wireless terminal identifier, while other types of assignments use a wireless terminal identifier and a mask identifier. The mask identifier, e.g., a single bit, allows for selection between a subset of the potential masks used in the system.

摘要： Systems and methodologies are described that facilitate detecting and/or identifying peers in a local area peer-to-peer network. Times (e.g., peer discovery intervals) for performance of mutual detection and identification between peers may be synchronized (e.g., based upon a signal broadcast to the peers), Further, within each partitioned peer discovery interval, a wireless terminal may select a portion of time to transmit (e.g., broadcast) short messages that may be employed by peers to detect and/identify the wireless terminal. Moreover, the remainder of the time within the partitioned peer discovery interval may be employed to listen to short messages received from peers.

摘要： Wireless devices, e.g., in a cognitive radio network, discover and use locally available usable spectrum for communication. Beacon signaling facilitates available spectrum discovery and spectrum usage coordination. A wireless terminal, which may have entered a new area and powered up, monitors to detect for the presence of beacon signals in a first communications band. The wireless terminal makes a decision as to whether or not to transmit based on the monitoring result. In addition, when beacon signals are detected, decoded information recovered by the wireless terminal from the received beacon signals is used in making the transmission decision. The decoded information includes, e.g., type information indicating that a second band is allowed to be used for peer-peer communications and/or identification information identifying at least one of a wireless communications device which transmitted the beacon signal and a current user of the wireless communications device which transmitted the beacon signal.

摘要： Systems and methodologies are described that facilitate encoding and/or decoding signals utilized to identify a wireless terminal during peer discovery interval(s). Substantially any type of function that constrains encoding and/or decoding within a peer-to-peer network may be utilized. For example, a reversible function may be employed that enables a receiving peer to discern an identifier of a transmitting peer over a series of peer discovery intervals. Pursuant to another example, an irreversible function may be utilized whereby a receiving peer may be unable to decipher the identifier of the transmitting peer from a received signal; however, expected signal formats of buddy peers may be compared to the received signal to determine a presence of one of the buddy peers in a vicinity.
