摘要： The present disclosure provides a method for triggering aperiodic Channel State Information (CSI) feedback used in a multiple coordinated cells multiple component carriers system. According to the present disclosure, a base station firstly semi-statically configures a user equipment to CoMP transmission modes, and/or information on measurement cells, and/or information on measurement component carriers by a high layer signaling (RRC signaling). Then, the base station dynamically initiates an aperiodic CSI feedback request to the user equipment by downlink control information (through PDCCH). When receiving the aperiodic CSI feedback request transmitted by the base station, the user equipment transmits measured aperiodic CSI to the base station through an uplink channel (PUSCH or PUCCH). According to the present invention, the method for triggering aperiodic CSI feedback in CoMP transmission modes can be flexibly configured, and good backward compatibility can be obtained at the same time. The above method is simple and effective, the system design complexity is low, and the design requirements for practical systems and LTE-Advanced evolved systems are met.

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 reduces a signaling size of an interference overload indicator. A base station includes an interference-overload-indicator generation control sub-system (1000), an interference-overload-indicator generation sub-system (2000), and a transmitting/receiving sub-system (3000). The interference-overload-indicator generation control sub-system (1000) judges whether or not a condition to initiate interference indicator generation is satisfied, and activates the interference-overload-indicator generation sub-system (2000) only when the condition is satisfied. This makes it possible to reduce a signaling size of the interference indicator. For further reducing the signaling size, an interference indicator signaling is generated by a method such as differential coding, state coding, or a bitmap, and transmitted. According to the present invention, an interference overload indicator generation control mechanism is relatively simple and the signaling size of the interference indicator is small.
