摘要： A method for accessing a hybrid network and a gateway communication system are disclosed. The method comprises: sensing by a gateway apparatus a relay request slot on a downlink common control channel of the wide area network; transmitting by a wireless terminal a relay request signal requesting to relay a data packet to be transmitted, in the relay request slot on the downlink common control channel; and if the relay request signal from the wireless terminal is sensed in the relay request slot, establishing by the gateway apparatus a connection with the wireless terminal in a distributed network environment. As such, the gateway apparatus accesses the wireless distributed network only when the surrounding wireless terminals require data relay, without sensing signals on both networks simultaneously.

摘要： Transmissions on a composite carrier including at least two component carriers can be controlled by means of a message by the provider of the carrier. The provider may receive a message from a device attempting to transmit on the composite carrier, and include in a response thereof an indication of at least one component carrier to be used by the device for a subsequent transmission. The device then received the message from the provider, and can determine based thereon at least one component carrier to be used by the device for at least one subsequent transmission, and transmit on the determined at least one component carrier.

摘要： The present disclosure provides methods and apparatus for fault protection for electronic devices (e.g., cold cathode fluorescent lamps). In one embodiment, a fault signal is detected and compared with a threshold to output a comparison signal. The comparison signal is then processed to generate a trigger signal, which triggers a fault control block once it satisfies certain fault conditions.

摘要： An embodiment of the present invention includes a medium access control method in a wireless distributed network which comprises the steps of: transmitting a CTS packet after delaying for an SIFS time interval, when a node in the network receives a RTS packet addressed to the node; detecting a channel and timing; if the channel is detected in idle within a time interval of the clearing threshold after the completion of the CTS packet transmission, then transmitting a clearing packet after the time interval of the clearing threshold is elapsed; resetting their current network allocation vectors of all the nodes receiving the clearance packet to zero. The techniques described herein resolve a problem of unnecessary setting of the network allocation vectors due to the transmission failure of the CTS. The throughput and time delay of the wireless system is improved by initiating information for clearing network allocation vectors by a receiver.
