摘要： A mobile device provides first information to an access point over an out-of-band wireless link. The access point uses the first information to coarsely synchronize with a macrocell base station. The access point transmits a low power pilot signal that is formed using a pseudo-random noise (PN) sequence. The mobile device uses the out-of-band wireless link to provide second information to the access point that indicates a PN phase of the pilot signal with respect to a reference time point. The access point uses the second information to finely synchronize with the macrocell base station. The mobile device communicates with a mobile operator core network through the access point using an in-band wireless link to the access point. The mobile device compensates for propagation delay when obtaining time information. The mobile device provides additional information to the access point, which the access point uses to adjust for continued clock drift.

摘要： Femtocell synchronization is disclosed, in which a femtocell transmits a request over an out-of-band (OOB) link to a proximate mobile device for synchronization assistance. In response to the request, the mobile device transmits an access probe to a serving macro base station. The femtocell detects the access probe and uses aiding information to decode the access probe to determine the timing and/or frequency information. The femtocell uses this timing and/or frequency information for its synchronization.

摘要： One feature includes a mobile device being used as a mobile beacon and proxy for a tracking device that may track an object, such as a pet. The mobile device may act as a beacon that transmits messages over a short range communications link to the tracking device. If the tracking device fails to receive the messages transmitted by the mobile device, it may be assumed that the pet has gone missing, and in response the tracking device may contact a tracking server with its location information via a wireless wide area network (WWAN). Additionally, the mobile device may act as a proxy of the tracking device by transmitting and receiving data to/from the tracking server using its own communication interface on behalf of the tracking device. This helps conserve the battery power of the tracking device because the tracking device does not use its own WWAN interface.

摘要： Techniques are provided for frequency and timing synchronization of a femto access point (FAP). In one example, the FAP may be configured to establish an out-of-band (OOB) link with at least user equipment (UE), and receive aiding parameters from the at least one UE via the OOB link. The FAP may be configured to extract frequency and timing information from at least one uplink packet of the at least one UE based at least in part on the aiding parameters. Extracting the frequency and timing information may involve sniffing the at least one uplink packet to a macro base station (e.g., eNB).
