    • 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.

    • To improve the frequency diversity effect by preventing the related bits in the encoded data from being biased to the specified carrier in the case of performing the multicarrier operation. A modulated symbol sequence is segmented in a data segmentation section (116), and the segmented modulated symbol blocks are mapped on a plurality of carriers in a segment mapping section (120). The data segmentation section (116) groups each of K parts in the modulated symbol sequence into the same number of N groups, cyclically shifts the N groups for the respective parts of any (K−1) parts with shift amounts which differ among the parts, and substitutes the cyclically-shifted groups of the plurality of parts in the modulated symbol sequence with one another among the parts to segment the groups into a plurality of blocks.
    • 在执行多载波操作的情况下,通过防止编码数据中的相关比特偏置到指定载波来提高频率分集效应。 调制符号序列在数据分割部分(116)中分段,并且分段调制符号块被映射在段映射部分(120)中的多个载波上。 数据分割部分(116)将调制符号序列中的K个部分中的每一个分组成相同数量的N个组,对任何(K-1)部分的各个部分的N个组进行循环移位,其中部分 并且将这些部分中的调制符号序列中的多个部分的循环移位组替换为将组分成多个块。
