摘要： Systems and methodologies are described that facilitate transmitting beacon symbols comprising static and dynamic information about the beacon and/or a transmitter thereof (or substantially any information a beacon transmitter desires to send). In this regard, the beacon symbol transmitter can select a subcarrier of bandwidth for transmitting the beacon symbol where the subcarrier is indicative of data and is in one of a plurality of subcarrier groups related to the total available subcarriers. Thus, the groups can have common virtual subcarriers such that a subcarrier index can be found in each group. In this way, the selected group can indicate additional information that can change based on what group is selected for transmitting a given beacon symbol.

摘要： Techniques for mitigating interference due to peer-to-peer (P2P) communication are described. In an aspect, a P2P UE may measure the signal strength of downlink signals from base stations and may set its transmit power based on (e.g., proportional to) the measured signal strength in order to mitigate interference to WWAN UEs communicating with base stations. In another aspect, the P2P UE may measure the signal strength of uplink signals from WWAN UEs and may set its transmit power based on (e.g., inversely proportional to) the measured signal strength in order to mitigate interference to the WWAN UEs. In one design, the P2P UE may measure the signal strength of an uplink signal from a WWAN UE, estimate the pathloss between the two UEs based on the measured signal strength, and determine its transmit power based on the estimated pathloss.

摘要： A method, a computer program product, and an apparatus are provided. In one configuration, the apparatus transmits a first broadcast signal including information indicating an intention to use a unicast resource for a broadcast. In addition, the apparatus transmits a second broadcast signal in the unicast resource. In another configuration, the apparatus, which is a first wireless device, receives a first broadcast signal from a second wireless device including information indicating an intention to use a unicast resource for a broadcast. In addition, the apparatus receives a first scheduling signal from the second wireless device in a scheduling resource. The first scheduling signal is for indicating a second intention to use the unicast resource for transmitting a second broadcast signal. Furthermore, the apparatus refrains from transmitting a second scheduling signal in the scheduling resource in response to the first scheduling signal.

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： Methods and apparatus for determining a mode of wireless communications to be used by a wireless terminal, e.g., a direct communications mode or an infrastructure communications mode are described. In some embodiments, the mode to be used is determined by a control node based on interference which will be caused to the system taking into consideration at least an area, e.g., cell, in which the wireless terminal seeking to communicate is not located. System interference cost estimates for each mode under consideration are generated and compared. Interference cost estimates may, and do, correspond to different frequency bands when the direct mode uses a different frequency band than the infrastructure communications mode. Separate interference cost estimates and mode determinations are made for different communications directions in some embodiments. The determined mode to be used is communicated to the devices seeking to communicate, e.g., via one or more base stations.

摘要： Methods and apparatus for supporting multiple modes of communication operation, e.g., with different parameters and/or frequency bands being used in the different modes of operation are described. One or more adjustments are made based on a signal or signals received in a first frequency band from a second communications device, e.g., an access router with reliable timing. The communications device selects between and operates in either the first frequency band, e.g., a WAN frequency band, or in a second frequency band, e.g., a LAN frequency band. The WAN and LAN frequency bands may be non-overlapping. One or more parameters used in the second frequency band have a predetermined relationship to one or more parameters used for communications in the first frequency band making the adjustment based on the signal received in the first frequency band relevant and useful to support communications in the second frequency band.

摘要： Methods and apparatus related to scheduling and/or utilization of air link traffic resources are described. A connection identifier is associated with priority with regard to use of an air link resource, e.g., a peer to peer traffic segment which is in contention. A particular connection may acquire and hold one or multiple connection identifiers. In some embodiments, the priority associated with a particular connection identifier is intentionally varied in a set of traffic slots. In some such embodiments, there is priority randomization from slot to slot. In one such implementation there is a statistically uniform average priority between the different connection identifiers over the recurring structure. Such an implementation facilitates access to traffic segments to a wide range of users, yet allows for differentiation with regard to the amount of access as a function of the number of connection identifiers being held by a particular connection.

摘要： One feature provides for establishing an ad hoc peer-to-peer network over an existing channel allocation for another network. To mitigate interference between multiple peer-to-peer devices, a plurality of receiver chains in a receiver device may be configured with beamforming coefficients so as to focus reception in the direction of an intended signal from a transmitter device while minimizing reception from other directions. Similarly, the receiver device may also use a plurality of antennas and a transmitter chain to beamform in the direction of the transmitter device, thereby focusing its transmission toward the transmitter device. The receiver device may also notify nearby devices that it is employing a plurality of receive antennas. This information can be used by the nearby devices to more intelligently perform transmitter yielding. By utilizing beamforming information to make the transmitter and/or receiver yielding decision, better interference mitigation may be achieved.

摘要： Methods and Apparatus for communicating information, e.g., control information, e.g., in the form of a control value, between communications devices, e.g., peer to peer communications devices, are described. Positional coding is used to encode a value to be communicated and the encoded value it then transmitted on a set of communications resources with the placement of signal energy on individual ones of the resources being used to create a pattern used to convey the value to be communicated. Resources, e.g., tone-symbols, which communicate unreliable signal portions due to interference are identified and not used in the positional decoding operation as either an energy carrying tone-symbol or a non-energy carrying tone-symbol.
