Abstract: The present invention provides a method and a coder for jointly coding Pre-coding Matrix Index #1 (W1) and Rank Index (RI) for channel state information feedback of a double codebook precoding frame. In the present invention, it is determined whether Rank Index RI is more than 2; if the RI is no more than 2, a first half branch of a coding binary tree is used to represent joint coding of the RI and W1 when RI=1 and RI=2; if the RI is more than 2, a second half branch of the coding binary tree is used to represent remaining separate codings and/or joint codings when the RI is more than 2; and processing results of the above coding steps are output. The present invention may be applied to an equal-length coding or an unequal-length coding. The present invention has advantages such as easy implementation, lower signaling overhead etc., and may be suitable for an LTE-A/4G cellular communication system and a future 5G cellular communication system.

Abstract: 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.

Abstract: 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.
