摘要： The present invention provides a precoding method for use in a wireless communications system. According to the precoding method of the present invention, a serving base station and cooperative communication base stations employ an identical precoding matrix so as to weight transmission signals and then transmit them. The weighting stands for multiplication of results of overall precoding or each layer precoding process by weight values at the serving base station and the cooperative communication base stations. A user device corresponding to the serving base station and the cooperative communication base stations receives a signal which is obtained by an operation in which the serving base station and the cooperative communication base stations perform an identical precoding process and additively combine results of overall precoding or each layer precoding process with one another. The user device feeds back information which includes (i) precoding matrix information for the serving base station and the cooperative communication base stations, (ii) weight vector information for either overall precoding or layer precoding, and (iii) a quantized value of channel quality. This feedback information is thus advantageous in that its signaling information amount is small.

摘要： The present invention discloses a channel reconstruction method for a downlink multi-antenna-multi-base-station with inconsistent antenna configuration. Firstly, a serving base station configures a user equipment. If antenna configuration of the multi-antenna-multi-base-station system is inconsistent, virtual antennas are introduced to a base station with fewer antennas in the system. A user equipment selects and feeds back indices of the virtual antennas and reconstructs channels of the multi-antenna-multi-base-station system to generate a consistent antenna configuration. Finally, the multi-antenna-multi-base-station system transmits a signal to the user equipment by adopting a transmission pre-processing scheme of the consistent antenna configuration. The present invention provides also a serving base station, a cooperative base station and a user equipment for realizing the channel reconstruction method. The present invention has advantages of large application range, simple implementation and better performance.

摘要： The present invention provides a method for allowing transparent transmission and non-transparent transmission of a relay node to coexist. That is, a frequency-division multiplex system is employed so that a transparent transmission mode is used in one operating carrier frequency bandwidth whereas a non-transparent transmission mode is used in another operating carrier frequency bandwidth. In addition, according to the frequency-division multiplex system, the transparent transmission mode is used for a plurality of subframes whereas the non-transparent transmission mode is used for another plurality of subframes. The method for allowing transparent transmission and non-transparent transmission of a relay node to coexist makes it possible to effectively reduce a cost of a system.

摘要： The present invention provides a relay collaborative cellular mobile communication system and a communication method of the system. In the method, all relay stations or a base station and relay stations in a cell (i) measure all uplink signals such as uplink reference signals and random-access signals from user devices for obtaining reception qualities of uplink signals of the user devices at the sites and (ii) feed back measurement results to the base station. The base station determines a transmission route of a user device based on the measurement results. A site in a transmission route processes schedule control information and then transmits the information to the user device for performing, based on lumped scheduling of the base station, a downlink reception, an uplink transmission, an uplink retransmission, or a downlink retransmission. In an uplink HARQ mechanism, the site in the transmission route receives an uplink signal from the user device, feeds back an ACK to the user device, and transmits a processed uplink signal to the base station, or feeds back an NACK or an ACK to the base station. The base station judges, based on results of decoding and detecting transmitted data or feedback results from the sites in the transmission route, whether or not the current uplink transmission is successful or whether to adjust the uplink retransmission.
