    摘要: Methods and apparatus are described for refining, e.g., reducing, a paging area corresponding to a user equipment device, e.g., a cellular inactive UE device. Various embodiments are well suited for communications systems in which user equipment devices participate in peer to peer communications networks in which direct user device to user device communications are employed. A user equipment device participating in a peer to peer network transmits discovery signals. A femto base station and/or a cellular active UE device in the local vicinity of the UE device transmitting the peer to peer discovery signal eavesdrops on the peer discovery signaling and detects the presence of the cellular inactive UE device. The detection of the cellular inactive UE device is reported to a MME. The MME determines a paging area corresponding to the detected UE device based on the reported information and the location of the reporting device.

    摘要: A method, an apparatus, and a computer program product for wireless communication are provided in connection with enabling timing source selection and deselection in a decentralized manner for distributed D2D synchronization in densely populated communications systems. In an example, a communications device, functioning in a non-timing source (TS) mode, is equipped to receive a request for timing information during a synchronization channel. The communications device may further be equipped to determine whether to switch to a TS mode based on a selection utility metric value. In another example, a communications device, functioning in a TS mode, is equipped to transmit a TIB during a synchronization channel, and determine whether to switch to a non-TS mode based on a deselection utility metric value. In the TS mode, the UE is configured to transmit a TIB, while in the non-TS mode the UE is configured not to transmit the TIB.

    摘要: A femto base station (BS) maintains two different timings: a femto BS downlink timing and a femto BS uplink timing. A femto base station's uplink reference timing is based on the macro uplink timing being used by one or more UE devices in the local vicinity of the femto BS. In some embodiments, the femto BS synchronizes its femto uplink timing to the macro uplink timing being used by the closest UE device transmitting uplink signals to the macro BS. In other embodiments, the femto BS determines its femto base station uplink timing based on one or more uplink signals from UE devices in its vicinity transmitting to the macro BS. In various embodiments, femto cell uplink signals and macro cell uplink signals are received at a femto cell BS in synchronization. This approach facilitates frequency division multiplexing (FDM) in the uplink between a macro cell and a femto cell.
