Title:
チャネル空間特性情報を取得するための方法及び基地局
Document Type and Number:
Japanese Patent JP6542370
Kind Code:
B2
Abstract:
Embodiments of the present invention provide a method for obtaining channel spatial characteristic information, and a base station. The method includes: separately sending, by a first base station, a channel spatial characteristic request and an identity of to-be-measured user equipment UE to multiple second base stations, where the channel spatial characteristic request is used to instruct the second base station to perform channel spatial characteristic information measurement on the to-be-measured UE; and receiving, by the first base station, channel spatial characteristic indication information sent by the multiple second base stations, where the channel spatial characteristic indication information carries channel spatial characteristic information of the to-be-measured UE. In the embodiments of the present invention, the channel spatial characteristic information can be obtained on all channels through which the first base station and the second base station communicate with the UE. Therefore, multipath at different angles or in different directions can be better distinguished, so that interference between multiple users is better avoided in a data transmission process by using this advantage for data transmission, and a massive MIMO technology is well applied to a system in which multiple base stations collaboratively communicate with UE.
