摘要： A method and Base station for Channel State Information estimation in a wireless network is proposed. The wireless network comprises at least one base station. The at least one base station comprises a Large Scalable Antenna System. The Large Scalable Antenna System antenna elements are partitioned in sub-arrays. Precoding vectors for each sub-array are generated such that the antenna beams of the sub-arrays point to different directions. At least one uplink pilot sequence is received by at least one antenna sub-array. A Channel State Information is estimated for the at least one antenna sub-array based on the received pilot sequence. The Channel State Information estimated for at least one antenna sub-array is extrapolated to the antenna elements of the Large Scalable Antenna System.
