Abstract: In a mobile communication system, if a UE enters a SHO (Soft Handover) region, the UE determines weight information for a DPCH and a PDSCH depending on DPCH signals and PDSCH signals received from Node Bs, and transmits the determined weight information to the Node Bs. The Node Bs then determine weights of the DPCH signals and the PDSCH signals to be transmitted to the UE depending on the feedback information received from the UE, and transmit the determined weights to the UE along with the DPCH signals and the PDSCH signals, respectively.

Abstract translation: 在移动通信系统中，如果UE进入SHO（软切换）区域，则UE根据从节点B接收的DPCH信号和PDSCH信号来确定DPCH和PDSCH的权重信息，并将确定的权重信息发送到节点 Bs。 然后，节点B根据从UE接收到的反馈信息来确定要发送给UE的DPCH信号和PDSCH信号的权重，并且将所确定的权重分别与DPCH信号和PDSCH信号一起发送给UE。

Abstract: 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 informatio, 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.
