Abstract: 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).

Abstract: A novel power conservation scheme is provided for conserving power in a wireless client terminal with an established communication session. While in a connected mode, the client terminal may receive data for the communication session via a data channel from an access point. During periods of inactivity over the data channel, the client terminal may switch to a lowered power mode, where the client terminal discontinuously monitors a control channel and does not monitor the data channel. The access point is informed of the operating mode of the client terminal. If a data resume indicator is received over the control channel, the client terminal switches back to the connected mode and resumes the communication session by receiving additional data over the data channel.
