Abstract: A method and a device for transmitting an Optical Channel Transport Unit signal are disclosed in the present invention. The method includes: receiving an Optical Channel Transport Unit OTUk signal after photoelectric conversion; wrapping the OTUk signal into an Optical Channel Data Unit (ODU) signal; multiplexing and mapping the ODU signal to an Optical Channel Payload Unit OPUj signal, where the OPUj signal is a High Order signal of the ODU signal; and wrapping the OPUj signal into an ODUj signal and an OTUj signal, and sending the ODUj signal and the OTUj signal. Through the embodiments of the present invention, fully transparent transmission of an OTU signal can be implemented.

Abstract: A sense amplifier includes a first inverter responsive to a first output of a latch. The first inverter is powered by a sense enable signal. The sense amplifier also includes a second inverter responsive to a second output of the latch. The second inverter is also powered by the sense enable signal.

Abstract: A base station apparatus communicates to a user apparatus in an uplink shared channel and controls transmit power for a PHICH (Physical HARQ Indicator Channel) on the shared channel. The transmit power for the PHICH is controlled based on downlink radio quality information (CQI) reported from the user apparatus, information (ACK/NACK) mapped into the PHICH and the presence of transmission of an uplink scheduling grant for indicating transmission of the shared channel.

Abstract: The invention relates to a method and system for implementing a relay channel, and an edge node, in which a media location service system monitors the number of orders of all nodes in an IPTV system, and, when monitoring that the number of orders of the central node of the IPTV system is more than a predetermined first threshold, searches edge nodes with the number of orders less than a predetermined second threshold, and sends a relay channel establishing request message to one of the edge nodes; the edge node which receives the message sends an RTSP link establishing request message to the central node, reserves a media distribute unit (MDU) resource for the link, and notifies the central node of the IP address of the reserved MDU resource; and the edge node enables the MDU resource, sends a media stream requesting message to the central node, and stores data of the relay channel.

Abstract: The specification and drawings present a new method, system, apparatus and software product for implicit signaling and defining uplink allocations for an acknowledgment of downlink data using user downlink resource allocations, e.g., combined with user equipment detection of other user's allocations for data-non-associated signaling of hybrid automatic request process (HARQ) control information. Sequences of the downlink resource allocations are used to pre-define associated uplink control signaling resources.
