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： 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).

摘要： Methods, systems, and devices are described for femtocells to retrieve neighboring macrocells' timing information, using messages from mobile devices that are associated with the relevant macrocell In some cases, detection of the femtocell, such as through an out-of-band detection, may trigger the mobile device to determine timing information with respect to the macrocell and/or the femtocell. In some embodiments, the mobile device associated with the macrocell may be in active state and looking for a candidate femtocell for handover. The femtocell may receive this timing information from the mobile device and utilize it to synchronize with the neighboring macrocell. Embodiments may address fine timing synchronization and tracking for asynchronous and quasi-synchronous wide-area wireless networks (e.g., 3GPP/3GPP2 variants like UMTS, LTE, CDMA 1x, 1x EV-DO, etc).
