Abstract: PURPOSE: A method and apparatus for mixed analog and digital beam-forming are provided to execute a digital beam-forming process for compensating for other terminals except for a first terminal using an analog beam-forming pre-coder fixed in the first terminal. CONSTITUTION: A pre-processor(124) executes a digital beam-forming process by multiplying a digital beam-forming pre-coder by a second sub carrier. The digital beam-forming pre-coder determines an analog beam-forming pre-coder for compensating for a second sub carrier transmitted to a second receiver. The analog beam-forming pre-coder is optimized for a first sub carrier transmitted to a first received in a parallel symbol stream. An RF(Radio Frequency) chain executes an analog beam-forming process by multiplying an analog beam-forming pre-coder by an analog signal. The analog beam-forming pre-coder is transmitted to one or more RF paths. The analog beam-forming pre-coder is optimized for the first sub carrier.

Abstract: PURPOSE: A device for increasing performance in an open loop multi cell MIMO(Multiple Input Multiple Output) system and a method thereof are provided to increase performance by PMI(Precoding Matrix Index) cycling or PMI repetition. CONSTITUTION: A controller(522) transmits the identifiers of a base station or a temporary base station to a serving base station wherein the base station has larger average power than a specific value. The controller receives information of a base station related to generated joint processing using a bitmap or a base station identifier. The controller feeds a transmission coherence matrix or a main eigen vector of a related base station back to the serving base station. The controller corresponds to the main eigen vector and receives a bitmap showing a PMI and a parameter showing a PMI cycle mode. The controller determines the PMI cycle mode according to the parameter.
