Abstract:
Methods and apparatus related to peer to peer communication networks are described. Embodiments directed to methods and apparatus for establishing traffic data transmission rates and/or transmission power levels between wireless terminals is described. Embodiments direct to methods and apparatus of making decisions whether or not to transmit as a function of the received power of the received response signals are also described. Transmission of pilot signals after granting of a transmission request and a decision to transmit traffic data has been made occurs in some embodiments. Rate information to be used in determining a traffic rate may be received in response to the pilot signal from a peer to peer (P2P) device.
Abstract:
A system and method are disclosed that may provide an accurate estimate of the angle of arrival (AoA) of a wireless signal received by a device. The received wireless signal may include a plurality of signal components associated with a number of different arrival paths. The device may generate a weighted signal, including a plurality of weighted signal components, by multiplying the plurality of signal components of the received wireless signal with a set of weighting values. The device may identify one or more of the weighted signal components associated with a first arrival path to the device, determine phase information of the one or more identified weighted signal components, and then determine the angle of arrival based, at least in part, on the determined phase information.
Abstract:
A method, an apparatus, and a computer program product for relaying a packet are provided. The apparatus receives at least one packet and reduces a degree of the at least one packet. The apparatus further processes the at least one packet based on the reduced degree, generates a combined packet by combining the at least one processed packet with at least one other processed packet based on the reduced degree and a weight of each of the processed packets, and transmits the combined packet.

Abstract:
Techniques and systems described herein provide for improved clock drift calibration of two or more clocks of two or more wireless devices. According to one example method, a first packet is received at a first wireless device from a second wireless device sent at a first time. The method may also include determining a first time-of-arrival estimate for the first packet. The method may further include receiving, at the first wireless device, a second packet from the second wireless device sent at a second time. The method may also include determining a second time-of-arrival estimate for the second packet and determining a relative clock drift between the first wireless device and the second wireless device based at least in part on the first time-of-arrival estimate and the second time-of-arrival estimate.
Abstract:
Methods and apparatus for capturing an image using an automatic focus are disclosed herein. In one aspect, a method is disclosed which includes communicating, using a camera, with a wireless device via a wireless communication network. The method further includes determining a distance between the camera and the wireless device using the wireless communication network and adjusting a focus of the camera based upon the determined distance. Finally, the method includes capturing an image using the adjusted focus of the camera. In some aspects, this method may be done on a smartphone or digital camera which includes Wi-Fi capabilities.
Abstract:
Techniques are provided for expedited Internet content delivery. For example, there is provided a method that involves receiving, at a communication device, a broadcast transmission outside of a spectrum allocated for Internet communications and outside of a spectrum allocated for real time programming content, wherein the broadcast transmission includes unsolicited content pushed to a group of such communication devices. The method may involve storing a portion of the unsolicited content, and receiving a request for content from a user. The method may involve providing the portion of the unsolicited content to the user, in response to the requested content matching the portion. The method nay involve determining whether the requested content is stored on another communication device of the group, in response to the requested content not matching the portion.
Abstract:
Methods, systems, and devices are described for utilization of an unlicensed radio frequency spectrum band for performing a ranging procedure. Performance of the ranging procedure may be triggered by a signal transmitted in a licensed radio frequency spectrum band. While conventional ranging in Long Term Evolution (LTE) communications, for example, using the licensed radio frequency spectrum band may be limited to a 10 MHz bandwidth, using the unlicensed radio frequency spectrum band for ranging may allow use of a wider bandwidth, such as 100 MHz or greater. Use of the wider bandwidth may result in more accurate ranging measurements (e.g., time-of-arrival estimation).
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).
