Abstract: Systems, methods, devices, and computer program products are described for supporting macrocell-to-femtocell hand-ins of active macrocell communications for a mobile device. A mobile device may perform an out-of-band (OOB) search for the femtocell, the OOB search triggered by a proximity detection configuration command from the macrocell. The mobile device may wirelessly communicate with a located femtocell via an OOB link, and receive femtocell information from the femtocell via the OOB link. The mobile device may transmit the received femtocell information to the macrocell. The macrocell may generate instruction for a mobile device search based on the femtocell information. The macrocell may transmit such instructions to the mobile device for an in-band search for the femtocell.

Abstract: A method and system provide assisted acquisition of a wireless link between user equipment and a femtocell unit. After an initial calibration of timing and/or frequency information, the user equipment enters into a low-power state. The femtocell unit monitors for system updates using a network listen module that sniffs the air interface of one or more neighboring cells. Upon a trigger event, the femtocell unit provides aiding information, for example, timing and/or frequency information corresponding to a change in timing and/or frequency of the air interface, over a second radio, e.g., a wireless personal area network interface. Thus, the user equipment may remain in the low-power state and receive updates with respect to the wireless wide area network interface. Subsequently, upon wake-up, the user equipment may utilize the aiding information, for example, to recalibrate its timing and/or frequency. Thus, acquisition of the wireless link with the femtocell unit may be expedited.

The first set of private data may not be shared among the plurality of mobile devices.

Abstract: A novel power conservation scheme is provided for conserving power in client terminals by using a proxy server. The client terminal, having a low-power communication interface and a high-power communication interface, may power down its high-power communication interface, to conserve power. Prior to shutting off its high-power communication interface, the client terminal may assign a host terminal to act as a proxy for the client terminal. The host terminal monitors the paging channels for the client terminal via a high-power communication interface. If the host terminal detects a paging message for the client terminal, it forwards at least a portion of the paging message to the client terminal via a low-power communication interface. Upon receipt of the paging message from the host terminal via its low-power communication interface, the client terminal may power up its high-power communication interface and directly respond to an access terminal that initiated the paging message.

Abstract: Systems and methods are provided for transceiving information via alternate bandwidths using a shared baseband processor. The transmission method selects clock sampling frequencies, for example a first clock frequency (l×F1), or a second clock frequency (k×F1), where k>l. Digital information is processed using the selected clock sampling frequency and a baseband signal is generated. Regardless of the clock sampling frequency selected, the baseband signal may have the same number of subcarrier frequencies. The baseband signal is converted into a radio frequency (RF) signal having a data rate responsive to a selected clock frequency, and transmitted. More explicitly, a first baseband signal is generated having a first data rate in response to selecting the first clock frequency. A second baseband signal having a second data rate greater than the first data rate, may be generated in response to selecting the second clock frequency.

Abstract: Techniques for extending coverage of a wireless communication network (e.g., a cellular network) to indoor and other locations are described. A wireless device may communicate with a base station in a wireless network via downlink and uplink frequency channels in a licensed frequency band using frequency division duplexing (FDD). The wireless device may communicate with a piconet base station (PBS) in a pico network (piconet) via the uplink frequency channel using time division duplexing (TDD). The PBS may communicate with the wireless device on the uplink frequency channel and may exchange data with the wireless network via a wireline communication link. The PBS may forward data received from the wireless device to the wireless network and may also forward data received from the wireless network for the wireless device to the wireless device. The PBS may receive paging messages from the wireless network for the wireless device and may forward the paging messages to the wireless device.

Abstract: A multipath transport protocol such as multipath TCP can utilize metrics such as a wireless link condition corresponding to one or more paths as a parameter for controlling a dynamic allocation of data and control signaling over respective paths. Fault-tolerant control can enable retransmissions of packets already sent on a poor path, onto a good path. Further, the feedback, the retransmissions, and other control signaling can be provided on a separate subflow or on a UDP overlay. In this way, a multipath TCP connection can be more reliable and efficient as flow control and data flow are enhanced.

Abstract: In general, techniques are described for preparing video data in accordance with a wireless display protocol. For example, a portable device comprising a module to store video data, a wireless display host module and a wireless interface may implement the techniques of this disclosure. The wireless display host module determines one or more display parameters of a three-dimensional (3D) display device external from the portable device and prepares the video data to generate 3D video data based on the determined display parameters. The wireless interface then wirelessly transmits the 3D video data to the external 3D display device. In this way, a portable device implements the techniques to prepare video data in accordance with a wireless display protocol.

Abstract: Out of band (OOB) communication facilitates femtocell operation. One or more proximity agent provides out of band communication with nodes (e.g., mobile client devices) to provide assistance in or otherwise facilitate femtocell discovery, reselection, and/or interference mitigation. Out of band communication techniques provide for low power discovery, association, and communication as compared to corresponding femtocell or cellular network communication techniques. An OOB proximity agent is provided in association with a femtocell to provide transmit power level control with respect to the femtocell. In operation, if a client device searches for and finds an OOB proximity agent, it will find a femtocell, thereby avoiding a need to aggressively search for femtocells.

A second baseband processing chip is selectively coupled with a second transceiver and a second UICC module to establish a second connection operable concurrently with the first connection. A multiplexer controller performs a configurable search for available networks. One or more networks are selected. The controller selects a specific transceiver for each selected network based on the capabilities of the transceiver.

Abstract: Methods, systems, and devices are described that may provide for femtocells to indicate the proximity of mobile user equipments and/or provide mobile identity to assist in resolving femtocell disambiguation. A femtocell may detect a user equipment in its proximity using an out-of-band link. The femtocell may transmit a proximity indication message to a macro network controller via a core network. The macro network may direct the user equipment to perform a variety of tasks, including directing the user equipment to do a handover to the femtocell. Some embodiments may utilize existing user equipment registrations and femto-to-macrocell outbound handover procedures to address problems such as femtocell ambiguity resolution and triggering frequency searches at a macro network when a current macrocell signal strength is good. These embodiments may utilize dummy identifiers to register the user equipment to facilitate addressing these problems.

The client receives the multiple descriptions and aggregates them together to ideally obtain the original content at its original quality; however, if one or more of the descriptions is lost in the transmission, then the entire content can be generated from the remaining one or more descriptions that did arrive successfully.

Abstract: Various features are provided to improve communication performance and power conservation in a client terminal by relying on the assistance of a proxy device. For instance, rather than reporting channel measurements via a primary communication channel to a network, the client terminal may be adapted to perform (a) channel measurement feedback using out-of-band signaling via the proxy device and/or (b) active synchronization with assistance of a proxy device. In this manner, the client terminal may be able to disable or reduce power consumption over a primary communication interface for the primary communication channel while utilizing a secondary communication interface to communicate with the proxy device.

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.
