摘要： The present invention provides a subband determining method, a base station, user equipment, and a communications system, each of which is used for information feedback. The base station of the present invention finds the subband size on the basis of a system bandwidth and divides the system bandwidth into subbands. The base station further (i) selects some subbands to form a subband set and assign the subband set to user equipment (UE) and (ii) notifies the user equipment (UE) of information about the subband set. The user equipment (UE) in turn finds its corresponding subband size and the number of subbands for use in feedback on the basis of the size of the assigned subband set. The user equipment (UE) further (i) divides the subband set into its corresponding subbands on the basis of a result found and (ii) feeds back information about a predetermined number of subbands to the base station. The base station carries out optimization of its transmitter on the basis of the information, fed back from the user equipment (UE), so as to not only secure a quality of service of a wireless cell, but also improve system efficiency. This method allows feedback to be carried out for downlink information with ease and high efficiency. This in turn reduces load for uplink wireless transmissions and improves feedback precision so as to save wireless resources and improve system efficiency.

摘要： The present invention provides an interference-overload-indicator generating device, a method of generating an interference overload indicator, an interference-overload-indicator generation controller, a method of controlling interference-overload-indicator generation, and a method of indicating interference overload, and a base station utilizing these methods, each of which is used in an uplink FDMA cellular communication system. The 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.

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 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.
