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 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.

摘要： Methods and apparatus for efficiently communicating small amounts of information relatively frequently in a wireless communications system are described. An access point's uplink timing frequency structure includes a set of dedicated uplink communications resources, e.g., expression advertisement interval air link resources, which may be in addition to regular traffic channel resources. The set of dedicated uplink communications resources comprises a small fraction of the total uplink communications resources. An individual one of the set of dedicated uplink communications resources can carry a small amount of information bits. An expression advertisement interval occurs relatively frequently. A wireless communications device, registered with the access point, is allocated one of the set of dedicated uplink resources. The wireless communications device can transmit information using its allocated resource in both a sleep state and an active state.

摘要： Systems and methodologies are described that facilitate sharing bandwidth between a wide area network and a local area peer-to-peer network. The peer-to-peer network may use an air interface technology that is similar to distinct from an air interface technology used in the wide area network. Moreover, the wide area network and the local area peer-to-peer network may utilize distinct sets of parameters. For example, if the wide area network and the peer-to-peer network use OFDM-based air interface technologies, parameters such as tone spacing, symbol time, cyclic prefix, and the like of the two networks may vary. Further, peer-to-peer parameters may be a function of parameters for the wide area network.

摘要： Methods and apparatus related to supporting rapid synchronization between groups of wireless communications devices are described. Described methods and apparatus are well suited for use in peer to peer wireless communications systems in which a plurality of ad hoc peer to peer networks may be formed, each ad hoc network operating with its own notion of time. As two groups of devices, having different notions of time, come within proximity of one another, a wireless communications device of a first group detects the presence of a member of a second group. The wireless device determines that network timing re-synchronization is to be performed by one of the first and second groups and transmits a re-synchronization alert signal on a dedicated resource. Subsequently, the wireless device transmits a timing synchronization signal in accordance with new timing. Intended devices, which detect the alert signal and timing synchronization signal, adjust their internal timing.
