Problems solved by technology

However, since TxAA modes 1 and 2 are defined under the assumption that the spatio-temporal channels of the two antennas are completely independent, the efficiency cannot be guaranteed when the number of antennas and spatio-temporal channel characteristics vary
In addition, TxAA modes 1 and 2 cannot yet be applied when using more than two antennas

Abstract

A mobile communication apparatus with multiple transmission and reception antennas and a mobile communication method therefore including a base station that restores long-term and short-term information from a received feedback signal, spatially processes dedicated physical channel signals using basis information generated from the restored long-term and short-term information, and transmits the results of adding pilot channel signals to the spatially processed results, to the base station, and a mobile station that determines a first characteristic corresponding to the channel downlink characteristic for each of the transmission and reception antennas using the PICH signals transmitted from the base station, determines the long-term and short-term information based on the first characteristic, converts the determined long-term and short-term information to a feedback signal, and transmits the feedback signal to the base station. Therefore, the invention can minimize the influence of interference and noise and increase the overpassing quantity of the transport data to reduce the influence of the decline.

Description

technical field [0001] The present invention relates to mobile communication, in particular to a mobile communication device with multiple transmitting and receiving antennas that can minimize fading, interference and noise effects and a method thereof. Background technique [0002] Next-generation mobile communication systems require faster high-speed data transmission than mobile communication systems for personal communication services. As a wireless communication standard, Europe and Japan have adopted the W-CDMA (Wideband-Code Division Multiple Access, wideband code division multiple access) scheme, while North America has adopted the CDMA-2000 scheme. [0003] A mobile communication system is generally constituted by a base station and a plurality of mobile stations communicating with each other via the base station. High-speed data transmission in a mobile communication system can be achieved by reducing inter-user interference and signal loss such as fading, which a...
