20120026934 | METHOD FOR ENABLING RELAY NODE TO TRANSMIT UPLINK CONTROL INFORMATION IN WIRELESS COMMUNICATION SYSTEM AND THE RELAY NODE - Disclosed is a method for enabling a relay node to transmit uplink control information. The relay node can receive resource allocation information and sequence information according to the transmission format of a physical uplink control channel set from a base station in advance. Additionally, the relay node can transmit the uplink control information, to which a sequence corresponding to the received sequence information is applied, in at least one slot of a resource area, which is indicated by the received resource allocation information, through a fixed number of symbols. | 2012-02-02 |
20120026935 | METHOD FOR DETECTING HARQ/NACK FEEDBACK SIGNAL FROM REPEATER - Disclosed is a repeater apparatus for detecting a downlink HARQ ACK/NACK feedback signal from a base station. An RF (Radio Frequency) unit receives specific channel configuration information which includes offset information indicating the starting point of a specific channel to which said HARQ ACK/NACK feedback signal is transmitted from the base station and the position of the specific channel allocated for an exclusive use of said repeater apparatus within said specific channel from said start point, and receives the HARQ ACK/NACK feedback signal from said base station for an uplink transmission of said repeater. The processor detects said specific channel allocated for exclusive use of the repeater apparatus based on said received specific channel configuration information thereby decoding said received HARQ ACK/NACK feedback signal. | 2012-02-02 |

20120026937 | ACCESSING LP TRANSPONDERS WITH CP TERMINALS VIA WAVEFRONT MULTIPLEXING TECHNIQUES - The invention is about a method and apparatus for grouping multiple satellite transponders with both (LP) polarization formats in different frequencies through Wave-Front (WF) Multiplexing (muxing) techniques for ground terminals with incompatible (CP) polarization formats. As a result of this invention, linear polarized (LP) transponders can be accessed and efficiently utilized by circularly polarized (CP) ground terminals and vice versa. This invention consists of conventional ground terminals, a unique organization of space assets, and a unique polarization alignment processor. The applications of wavefront multiplexing techniques to satellite communications offer many potential advantages, including improved flexibility and utility efficiency of existing space assets. Our proposed “Polarization Utility Waveforms” is an entirely new concept in VSAT and Earth Station Antenna diversity.
