摘要： 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.

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： Techniques for performing automatic gain control (AGC) at a terminal in a wireless communication network are described. In an aspect, the terminal may use different receiver gain settings to receive different types of signals in different time intervals. The terminal may determine a receiver gain setting for each signal type and may use the receiver gain setting to receive signals of that signal type. In another aspect, the terminal may determine a receiver gain setting for a future time interval based on received power levels for peer terminals expected to transmit in that time interval. The terminal may measure received power levels of signals received from a plurality of terminals. The terminal may determine a set of terminals expected to transmit in the future time interval and may determine the receiver gain setting for the future time interval based on the measured received power levels for the set of terminals.

摘要： Methods and apparatus for using different frequency bands are described. In some embodiments a first frequency band which is a licensed spectrum frequency band is used for peer discovery, device authentication, session establishment between peer devices and/or supporting an ongoing communications through control signaling. When available, a second frequency band, e.g., an unlicensed public frequency band is used for communicating data while the communications session is maintained using one or more control signals communicated in the first frequency band. Data and control signaling may be performed on a time division basis during a time period in which data is communicated.

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： Systems and methodologies are described that facilitate paging within a peer-to-peer communication network. A first wireless terminal monitors the paging channel of a wide area network. When a second wireless terminal intends to establish a peer-to-peer connection with the first wireless terminal, the second wireless terminal generates a paging message and transfers the message to the WAN, which routes the paging message to a base station. The base station uses its paging channel to send a paging message to the target first wireless terminal. The paging message indicates to the target first wireless terminal that the second wireless terminal intends to establish a peer-to-peer connection with the first wireless terminal. The paging message may further include parameters to be used to establish the peer-to-peer connection. Upon reception of the paging message, the second wireless terminal sends a signal directly to the first wireless terminal to start the direct peer-to-peer communication.

摘要： 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.
