Furthermore, the invention is also related to the operation of Node B and relay node regarding the generation, transmission and reception of such special sub-frame format. The invention is inter alia applicable to a 3GPP LTE-A system as standardized by the 3rd Generation Partnership Project (3GPP). The invention suggests a new structure for a sub-frame that is capable of conveying control information and/or data for a relay node to the relay node essentially independent from propagation delays. The structure of the sub-frame takes into account propagation delays of the radio signal from Node B to relay node, in that control information and/or data for a relay node is transmitted from the Node B on OFDM symbols that can be expected to be received by the relay node. | 2012-04-19 |
20120093066 | MOBILE COMMUNICATION SYSTEM - A radio base station includes a mobile communication system, a first relay node and a second relay node connected via a radio bearer. The second relay node and a radio base station are connected via a radio bearer. A mobile station is configured to perform a handover process between the state in which a radio bearer is set with the first relay node in order to communicate via the first relay node, the second relay node, and the radio base station, and the state in which a radio bearer is set with the second relay node in order to communicate via the second relay node and the radio base station. The mobile station is configured such that, during the handover process, control signals involved in the handover process are sent and received via the radio bearer between the first relay node and the second relay node. | 2012-04-19 |
20120093067 | METHOD, BASE STATION, AND RELAY DEVICE FOR RECEIVING PHYSICAL UPLINK CONTROL INFORMATION - A method, base station, and relay device for receiving physical uplink control information are disclosed in the present invention. The method includes: selecting a PUCCH resource of the relay, where the PUCCH resource can form multiplexing with a first resource, and the first resource includes the PUCCH resource occupied by a 3GPP LTE terminal when the terminal transmits the physical uplink control information in a first format; determining a channel index corresponding to the PUCCH resource of the relay; transmitting notification information to the relay, where the notification information includes the channel index; and receiving the physical uplink control information transmitted, according to the channel index, by the relay. In the embodiments of the present invention, the interference between the PUCCH format 1/1a/1b channel of the relay and that of the LTE R8 terminal is effectively reduced. | 2012-04-19 |
20120093068 | RELAY STATION, RECEIVING STATION, TRANSMITTING STATION, AND PACKET COMMUNICATION SYSTEM - A relay station relays packets between a transmitting station and a receiving station, and when a transmission packet affixed with a packet number is received, the relay station generates a divided data unit by dividing the data included in the transmission packet, then generates a divided packet including the divided data unit affixed with the packet number and dividing position information indicating the dividing position of the divided data unit, and transmits the divided packet to the receiving station. Alternatively, the relay station generates a divided data unit by dividing the data in the received transmission packet, then generates a divided packet including the divided data unit affixed with a new packet number, and transmits the divided packet to the receiving station. An ARQ process is executed using the dividing position information or the new packet number included in the divided packet. | 2012-04-19 |
