| 20100226305 | COMMUNICATION SYSTEM INCLUDING RELAY STATION AND DATA FRAME FOR THE COMMUNICATION SYSTEM - Provided is a communication method and a data frame for a communication system having a relay station. An uplink sub-frame of the data frame may include a first uplink relay sub-frame which corresponds to a time frame where relay stations selected among a plurality of relay stations simultaneously transmit uplink relay signals to a base station, and a second uplink relay sub-frame which corresponds to a time frame where the remaining relay stations transmit remaining uplink relay signals to the base station using a scheduled radio resource. A downlink sub-frame of the data frame may include a first downlink relay sub-frame which corresponds to a time frame where a base station simultaneously transmits downlink relay signals to relay stations selected from among a plurality of relay stations, and a second downlink relay sub-frame which corresponds to a time frame where the base station transmits remaining downlink relay signals to the remaining relay stations using a scheduled radio resource. | 2010-09-09 |
| 20100226306 | Radio communication terminal and radio communication system - A radio communication terminal and a radio communication system which can avoid an obstacle that is caused by a malicious wormhole while using a harmless wormhole. There are provided: a radio communication terminal in which a relay route about a certain node is stored as a backup route about the node and the backup route is changed and set as a relay route about the node in accordance with a detection of an obstacle caused by application data; and a radio communication system in which a sink node transmits a transfer destination change command in association with the change setting and a node which received the command sets a node of a transferring source of the command as a transfer destination node. | 2010-09-09 |
| 20100226307 | ROUTING OF DOWNLINK CHANNELS IN A COMMUNICATIONS SATELLITE - For selectively routing downlink frequency channels to downlink beams of a communications satellite, the inherent routing functionality of a normal bandwidth multiport amplifier (MPA) is exploited in conjunction with the grouped channel filter characteristics of an output multiplexer (OMUX). In this arrangement the guard bands inherent in the OMUX mitigate the poor inter-port isolation inherent in the MPA so that two low performance elements in combination can be used to achieve an improved performance at system level. | 2010-09-09 |
