Channel state information processing method, device and system

Abstract

The present invention discloses a method, device and system for processing channel state information. The method comprises that the UE receives high-level configuration signaling, wherein the high-level configuration signaling includes a plurality of power parameters corresponding to rank information RI; the UE uses the received CSI ‑RS or CRS perform channel measurement; UE uses channel measurement results and power parameters to determine CSI and report CSI. The invention improves the performance of the system and improves the calculation accuracy of the channel quality information.

Description

Channel state information processing method, device and system technical field The present invention relates to the field of communications, and in particular, to a channel state information (Channel State Information, CSI for short) processing method, device and system. Background technique In wireless communication technology, when the base station side (e.g., evolved Node B, eNodeB, eNB for short) uses multiple antennas to transmit data, it can adopt spatial multiplexing to increase the data transmission rate, that is, use the same time-frequency The resource transmits different data at different antenna positions, and the receiving end (for example, user equipment UE) also uses multiple antennas to receive data. In the case of a single user, the resources of all antennas are allocated to the same user, and this user exclusively occupies the physical resources allocated to the base station side within a transmission interval. This transmission method is called Single Us...
