摘要： Systems and methods for reducing overhead in a communication system are disclosed. Different frame types are aggregated into an enhanced aggregated frame in response to a determination that the different frames are suitable for transmission within a single reservation period. In an embodiment, at least two frames of different types are identified, the suitability of an aggregated frame comprising at least a portion of each of the at least two frames for transmission during a first time duration is determined, and if suitable the aggregated frame is formatted for transmission by a transceiver. If unsuitable for transmission in the first time duration, a second time duration longer than the first time duration in which the aggregated frame is suitable for transmission is defined, and the aggregated frame is formatted for transmission by the transceiver.

摘要： Systems, methods, devices, and computer program products are described for using communications over an out-of-band (OOB) link to support compressed mode communications by user equipment (UE) in a femto deployment. Typically, UEs must tune away from an active communications channel to make inter-frequency and/or inter-RAT measurements. When making these measurements, data communications may be compressed to allow time to tune away for those measurements. Embodiments integrate an OOB proxy with the femtocell to provide OOB link capability to supplement WWAN link resources. According to various techniques, the OOB link is used to compensate for reductions in data rate and/or quality resulting from compressed mode operation. For example, the OOB link is used to communicate compressed mode signaling data, retransmissions, and/or other compensatory data.

摘要： Proxy devices simultaneously support multiple modes of client device operation. Embodiments facilitate continued support of idle mode, proxy state operation of one or more client devices by a proxy device that is serving an active connected mode proxied client device. Paging message delivery from the proxy device to an idle mode proxied client device is facilitated by the proxy device monitoring a channel associated with the active connected mode proxied client device for a message (e.g., paging message) associated with the idle mode proxied client device.

摘要： A power conservation scheme is provided for conserving power in an access terminal that includes a dedicated proxy circuit, a receiver/transmitter chain, and/or a baseband processor. The baseband processor is adapted to determine when a wireless communication link with an access network has been inactive for at least a threshold amount of time. If such inactivity is ascertained, the baseband processor sends a proxy request to the proxy circuit. Upon receiving such proxy request, the proxy circuit monitors a data, control, and/or paging channel on behalf of the access terminal while the baseband processor is powered down. If a signal is received for the access terminal over the monitored channel, then a wake-up signal is sent to the baseband processor to cause it to power up and monitor a data channel. Upon receiving a response from the baseband processor, the proxy circuit may stop operating as a proxy.

摘要： 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.

摘要： 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.

摘要： Wireless video transmissions over a MAC layer employ various techniques to improve throughput which may negatively impact latency, such as Block-ACK and data aggregation. To improve latency while continuing to improve throughput, data packets are fenced according to application layer specifications and then transmitted. For video data, Block-ACK sequences and aggregation sequences are terminated at the end of video frames or video slices. For data aggregation, a physical layer data packet concludes at the end of a video frame or slice. The application layer can indicate to the MAC layer when such packet fencing is to occur. In use with 802.11n transmission a data flag may be used by the MAC layer to facilitate fencing.

摘要： 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.
