Data transmission method and apparatus based on joint space division multiple access technology in collaborative downlink MIMO system |
摘要 |
A channel condition information feedback method and apparatus are provided for a collaborative wireless communication network using a multiple input multiple output antenna system. The apparatus includes a downlink channel estimator that estimates channels of adjacent base stations, groups base stations from among the adjacent base stations that are capable of collaborative communication, and obtains a maximum singular vector to base stations belonged to a same group; and a vector selector which selects a weight vector most accurately representing the maximum singular vector and a complex variable most accurately representing the maximum singular vector in combination with the weight vector. |
