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： Methods and apparatus related to peer to peer communication networks are described. A wireless communications device supports peer to peer communications with multiple peers. The wireless communications device determines its transmit timing synchronization based on a reference signal received from a node such as a base station, a satellite, or a beacon transmitter which does not transmit user data. The wireless communications device determines a plurality of different receive timing adjustments corresponding to different peer communications devices based on signals received from those peer communications devices. The wireless communications device stores the plurality of determined receive timing adjustment information corresponding to the different peer communications devices. The wireless communications device retrieves and applies stored receive timing adjustment information which matches the particular device which transmitted the signal attempting to be recovered.

摘要： Methods and apparatus related to peer to peer communication networks are described. A peer to peer timing structure is implemented which includes a pattern of different types of time intervals including at least a peer discovery time interval and a traffic interval. A wireless communications device, supporting peer to peer operations stores the peer to peer timing structure information, accesses the stored information, and used the accessed information to determine an operation to be performed during a current time period. The operation is, e.g., a peer discovery operation, a peer to peer timing synchronization operation, a peer paging operation, or a peer to peer traffic signaling operation. Various exemplary relationships between the different types of intervals, including relative frequencies, relative durations, and spacing information, are described. Advantageous construction of the recurring peer to peer timing structure facilitates efficient utilization of air link resources and/or higher traffic data throughput capabilities.

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： Methods and apparatus for communicating the location of a mobile wireless communications device are described. Codewords, e.g., values or sets of bits, are selected from a codebook mapping different codewords to corresponding pieces of location information. In a first approach location information is communicated by using codewords from different codebooks with the product, e.g., intersection of location information provided by the codewords, providing relatively detailed location information using relatively few bits. In a second approach user specific codebooks are defined for individual users. The codewords in the codebook corresponding to a particular user map to locations the individual specific user is likely to frequent. In another approach codewords are transmitted at different power levels and/or using different coding rates. Received codewords corresponding to a device may be used in combination to determine the location or refine the understanding of the device location.

摘要： Techniques for transmitting signals using time hopping or time and frequency hopping are described. In one design, a terminal selects different slots to use for transmission in multiple frames with time hopping. Each frame includes multiple slots, and each slot covers a particular time duration. The selected slots are at different time locations in the multiple frames. In another design, a terminal selects different resource units to use for transmission in multiple frames with time and frequency hopping. The selected resource units are at different time and frequency locations in the multiple frames. For both designs, the terminal sends a signal (e.g., a peer discovery signal) in the selected slots or resource units in the multiple frames. The terminal may detect for signals (e.g., peer discovery signals) from other terminals in slots not used for transmission by the terminal.

摘要： Techniques for performing automatic gain control (AGC) at a receiver are described. The receiver may receive an OFDM-based symbol composed of a cyclic prefix and a useful portion. The receiver may scale the OFDM-based symbol with an initial receiver gain, adjust the initial receiver gain based on the cyclic prefix, apply the adjusted receiver gain prior to the useful portion, and process the useful portion to recover at least one signal sent by at least one transmitter. The receiver may select the initial receiver gain, e.g., based on a predicted received power level for the at least one transmitter, a pattern of different receiver gains, etc. The receiver may apply the initial receiver gain at the start of the OFDM-based symbol. The receiver may measure the power of a set of samples in the cyclic prefix and may adjust the receiver gain based on the measured power and a target power.

摘要： A wireless terminal detects timing signals from different local timing signal sources. The wireless terminal selects from the plurality of detected timing signal sources two timing signal sources in accordance with a predetermined timing signal source priority ordering. In some embodiments, the wireless terminal intentionally selects two timing signal sources which are not synchronized with respect to one another. The wireless terminal determines a first set of peer communications time intervals corresponding to a first selected timing signal source and a second set of peer communications time intervals corresponding to a second selected timing signal source. The wireless terminal transmits a peer to peer signal, e.g., a peer discovery signal, during at least one of the first set of peer communications time intervals. The wireless terminal transmits a peer to peer signal, e.g., a peer discovery signal, during at least one of the second set of peer communications time intervals.
