METHOD AND DEVICE FOR QUANTIFYING CHANNEL STATE INFORMATION

摘要

Disclosed are a method and device for quantifying channel state information. The method can be implemented on a base station side according to an embodiment of the present invention, the method comprising: broadcasting the antenna configuration of the base station to a user equipment (UE), the antenna configuration comprising a vertical antenna port and a horizontal antenna port; transmitting a reference signal to the UE; receiving back from the UE a vertical precoder corresponding to the vertical antenna port and a horizontal precoder corresponding to the horizontal antenna port; and based on the received vertical precoder and the horizontal precoder, using a vertical codebook corresponding to the vertical antenna port and a horizontal codebook corresponding to the horizontal antenna port to reconstruct precoders.
