摘要： An apparatus and method for performing beamforming for transmitting a plurality of bit streams output through Adaptive Modulation and Coding (AMC) via a plurality of transmission antennas in a base station using a multi-antenna scheme. The apparatus and method include classifying the plurality of transmission antennas into a plurality of transmission antenna groups; selecting one of the transmission antenna groups depending on a group selection signal being fed back from a mobile station; and outputting each of the bit streams to its associated transmission antenna among the transmission antennas constituting the selected transmission antenna group.

摘要： Provided are a mobile communication apparatus including an antenna array and a mobile communication method. The mobile communication apparatus has a base station and a mobile station. The mobile station measures the downlink characteristics, detects physical space information and approximate long-term information, produces short-term information, transforms the short-term information and the physical space information into a feedback signal, and transmits the feedback signal to the base station. The base station receives the feedback signal, extracts weighted information, beamforms dedicated physical channel signals, combines pilot channel signals with the result of the beamforming, and transmits the results of the combinations to the mobile station via the antenna array. The physical space information denotes space information about the location of the mobile station with respect to the base station, and the approximate long-term information denotes long-term information. Accordingly, degradation of the performance of communications caused by a great amount of information to be fed back station can be prevented while keeping a beamforming gain.
摘要翻译：提供一种包括天线阵列和移动通信方法的移动通信装置。移动通信装置具有基站和移动台。移动站测量下行链路特性，检测物理空间信息和近似长期信息，产生短期信息，将短期信息和物理空间信息转换为反馈信号，并将反馈信号发送到基站。基站接收反馈信号，提取加权信息，波束形成专用物理信道信号，将导频信道信号与波束形成结果相结合，并通过天线阵列将结果结果发送给移动台。物理空间信息表示关于移动台相对于基站的位置的空间信息，近似长期信息表示长期信息。因此，可以在保持波束形成增益的同时防止由大量反馈站信息引起的通信性能的劣化。
