Embodiment Construction

[0032] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0033] The invention provides a CSI processing method, figure 1 It is the first flow chart of the CSI processing method according to the embodiment of the present invention, including the following steps S102 to S108.

[0034] In step S102, the UE receives high-layer configuration signaling, wherein the high-layer configuration signaling includes a plurality of power parameters corresponding to RIs.

[0035] In step S104, the UE uses the received CSI-RS or CRS to perform channel measurement.

[0036] In step S106, the UE uses the channel measurement result and the power parameter to determine CSI, and reports the CSI.

[0037] Preferably, the power parameter is an adjustment value parameter p-C of...

Abstract

The invention discloses a channel state information (CSI) processing method, device and system. The method comprises the following steps: UE (User Equipment) receives high-layer configuration signaling, wherein the high-layer configuration signaling comprises a plurality of power parameters corresponding to rank information (RI); the UE performs channel measurement by using a received CSI-RS (Channel State Information-Reference Symbol) or CRS (Common Reference Signal); and the UE determines the CSI by using a channel measurement result and the power parameter and reports the CSI. By adopting the method, the device and the system, the system performance is enhanced and the computing accuracy of channel quality information is enhanced.

Description

technical field [0001] 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 [0002] 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 User Multiple Input Multiple Output (SMUMO). -Inpu...
