Abstract: A method, system and computer program product for a wireless mobile display digital interface (WMDDI) association procedure that allows establishing and joining more than one multicast group to facilitate the interoperability of multiple client devices based on host and client capabilities. The protocol provides for the exchange and update of capabilities and multicast addresses for layered multicast transmission applications. The system is used for interoperating devices with different capabilities and provides for efficient transmissions by using different multicast addresses mapped to different layers of a bitstream. The protocol adapts to changes in capabilities, in joining/releasing of multicast addresses and in link quality.

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: 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: An apparatus for detecting forward and reverse link imbalances in a digital cellular communication system is provided. An indication of maximum access probes is used to determine whether a link imbalance caused a reverse link failure to occur. The maximum access probes condition indicates that a wireless unit has attempted to access a base station a pre-defined maximum number of times. An indication of a lost paging channel and a traffic channel initialization (TCI) time out is used to determine whether a link imbalance caused a forward link failure to occur. If the wireless unit did not lose the paging channel, the apparatus determines whether a TCI time out occurred. If the wireless unit lost the paging channel, or it did not lose the paging channel but a TCI time out occurred, the apparatus determines the cause for the forward link failure.

Abstract: A method and apparatus for dynamically adjusting a power control loop that attempts to maintain either the transmit power of a signal sent from a base station to a mobile station or the signal to noise ratio of a signal sent from the mobile station to the base station above a minimum threshold. Location information that is representative of the distance and morphology between the mobile station and the base station is determined. The minimum threshold of the power control loop is then adjusted in accordance with the location information such that the minimum threshold varies as the distance and the morphology between the mobile station and the base station change. A transmitter sends the signal at a power level that is controlled by the power control loop with the adjusted minimum threshold.
