Abstract: 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.

Abstract: Methods and apparatus related to peer to peer communication networks are described. A peer to peer timing structure is implemented which includes recurring peer discovery intervals and traffic intervals. Some embodiments further include recurring paging intervals for peer to peer pages. A wireless communications device, supporting peer to peer communications and storing information defining the timing structure, determines a time reference point, facilitating a coarse level of synchronization with respect to the timing structure. The time reference point is determined based on a broadcast signal received from a communications device, e.g., a satellite, base station, or beacon signal transmitter. Multiple peer to peer wireless communications devices in a local vicinity thus obtain the same basic understanding as to the current relative point in time with respect to a common recurring peer to peer timing structure. Peer to peer timing synchronization is further refined based on received signals communicated between peers.

Abstract: Systems and methodologies are described that facilitate identifying peers based upon encoded signals during peer discovery in a peer to peer network. For example, direct signaling that partitions a time-frequency resource into a number of segments can be utilized to communicate an identifier within a peer discovery interval; thus, a particular segment selected for transmission can signal a portion of the identifier, while a remainder can be signaled based upon tones communicated within the selected segment. Moreover, a subset of symbols within the resource can be reserved (e.g., unused) to enable identifying and/or correcting timing offset. Further, signaling can be effectuated over a plurality of peer discovery intervals such that partial identifiers communicated during each of the peer discovery intervals can be linked (e.g., based upon overlapping bits and/or bloom filter information).

Abstract: To make efficient use of a frequency spectrum, a peer-to-peer network shares a wide area network (WAN) frequency spectrum as well as a time-frequency structure of the WAN, where the time-frequency structure includes a set of tones and symbols of an OFDM system. A first wireless terminal monitors the time-frequency structure of the WAN to determine which subsets of tone-symbols are unused for WAN and/or other peer-to-peer connections. Then, the first wireless terminal selects and uses an unused subset of tone-symbols within the time-frequency structure for its peer-to-peer connection with a second wireless terminal..

Abstract: 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.

Abstract: One or more bits are used in peer discovery signals to signal a device's ability and/or willingness to participate in a cooperative manner with regard to one or more mobile device location determination related operations. In some embodiments, the one or more bits are located at predetermined locations within a header portion of a peer discovery signal. Different bits, in some embodiments, are associated with different specific cooperative location determination related operations. The peer discovery signal is transmitted, e.g., broadcast, periodically or on some predetermined basis by a mobile wireless communications device. In this manner, a device listening to the peer discovery signals can determine other devices' willingness to perform particular location discovery related operations with very little signaling overhead.

Abstract: Signal measurements are received, e.g., by a network device such as a location determination server, and a location of a mobile device to which the signal measurements correspond is determined. The measurements are also used to update parameters used to generate a signal prediction map. The signal prediction map, generated using the updated parameters, is then used for determining the position of another mobile device. In some embodiments parameter updating is performed when the location of a device is determined to a predetermined degree of certainty but not when the position of a mobile device is determined with a lower degree of certainty. Parameters used for generating prediction maps are updated, e.g., refined, based on signals collected for use in determining the location of a device without the need to conduct an updated survey and/or take signal measurements specifically for the purpose of updating prediction map parameters.

Abstract: To mitigate interference between multiple peer-to-peer devices, transmitter yielding and/or receiver yielding may be performed among devices operating in a peer-to-peer network. Generally, a transmitter device will yield communications on a time slot to a higher priority transmitter device if it will cause unacceptable interference to a higher priority receiver device. Likewise, a receiver device may yield use of the time slot if interference is unacceptably high. Both transmitter and receiver yielding may be improved by use of beamforming at a receiver device. By utilizing beamforming information to make the transmitter and/or receiver yielding decisions, better interference mitigation may be achieved.

Abstract: A peer to peer communications system implements scheduling of traffic intervals in a distributed manner utilizing connection priority and interference information. A peer to peer timing structure includes a user scheduling interval (2210), with ordered transmission request and response intervals, and an associated traffic interval. The priority associated with a request of an early interval is higher than the priority of a request of a later interval. A first device, connected to a second device, makes a decision as to whether or not to yield the traffic interval as a function of estimated interference that it will impose on higher priority connection receivers if it transmits during the traffic interval. The second device makes a decision as to whether or not to transmit a positive transmission request response signal as a function of a generated received signal quality value, based on received requests for its own and for higher priority connections
