一种终端、基站和获得信道信息的方法技术

本申请涉及移动通信领域，尤其涉及无线通信系统中获取信道状态信息的技术。在一种获得信道信息的方法中，基站根据终端发送的上行参考信息获得部分信道的信道状态矩阵信息和终端上报的该基站和终端之间信道的一部分信道状态信息来获得该基站与终端之间信道的信道状态矩阵信息。通过该方法可以获得比较完整的基站和终端之间信道的信道状态矩阵信息，有利于基站选择合适的参数来传输数据至终端，而不会带来额外的延迟、性能损耗、成本增加或者用于上行参考信号的时频资源的消耗。

A Method for Terminal, Base Station and Channel Information Acquisition

This application relates to the field of mobile communication, in particular to the technology of acquiring channel state information in a wireless communication system. In a channel information acquisition method, the base station obtains the channel state matrix information of part of the channel from the upstream reference information transmitted by the terminal and part of the channel state information of the channel between the base station and the terminal reported by the terminal to obtain the channel state matrix information of the channel between the base station and the terminal. By this method, more complete channel state matrix information between base station and terminal can be obtained, which is helpful for base station to select appropriate parameters to transmit data to terminal without additional delay, performance loss, cost increase or consumption of time-frequency resources for upstream reference signal.
