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： The claimed subject matter relates to enabling antenna switching in a wireless terminal that has multiple receive antennas per receive chain via soft-demodulation and interleaving of concatenated code received in a strip channel. A coherent demodulation protocol may be performed to estimate an SNR for a first antenna during a first time period, and a non-coherent demodulation protocol may be utilized on the strip channel to estimate an SNR for at least one other antenna during a second time period. SNRs may be compared and the terminal may select the antenna with the highest SNR for a next transmission superslot.

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.

摘要： A wireless terminal includes an uplink rate option indicator in the same uplink channel segment with data, the rate option indicator providing transmission rate information about the data transmitted in the segment. The indicator value is represented by an energy pattern within the segment. Different energy patterns correspond to different indicator values. The number of indicator values is less than the number of possible uplink data rate options supported by the wireless terminal. A single indicator value represents different uplink data rate options, at different times, as a function of a received maximum data rate option and/or type of assignment message. The maximum data rate option and/or assignment message was transmitted by the same base station receiving the indicator value; therefore, there is no ambiguity between wireless terminal and base station as to the interpretation of the uplink data rate option indicator value with respect to an individual uplink segment.

摘要： Different NAK signals are used to indicate different relative levels of success in regard to an unsuccessful attempt to decode a received signal. An ACK signal is used in the case of successful decoding. The device which generated and transmitted the original encoded signal receives the NAK signal and selects a portion of redundant information, e.g., additional error correction bits, to be transmitted based on the value of the NAK signal. If the NAK signal indicates a low level of decoding success indicating a relatively large number of errors in the decoded signal, a large set of redundant information is selected and transmitted. If the NAK signal indicates a relatively successful decoding, e.g., relatively few errors, a small set of redundant information is selected and transmitted. Where a small set of redundant information is transmitted new information can be transmitted with the redundant information.

摘要： A composite signal includes a high power beacon signal and low power corresponding wideband synchronization signal and is communicated over a time interval exceeding a single OFDM transmission time interval. A base station transmits one or more different such composite broadcast signals in a recurring timing structure. Each different potential beacon signal, e.g., a single tone signal, is paired with a unique wideband synchronization signal. A wideband synchronization signal includes at least some predetermined null tones and at least some predetermined non-null tones. For a given wideband synchronization signal, the predetermined null tones carry predetermined modulation symbol values, A wireless terminal receives a composite signal, identifies a beacon, determines a corresponding known wideband synchronization signal, compares received to known wideband synchronization signals, and determines at least one of a timing adjustment, frequency adjustment and channel estimation.
