Abstract

The embodiment of the present application discloses a channel state information measurement method and related equipment, wherein the method may include: the terminal equipment determines the first frequency resource, and the Z sub-frequency bands included in the first frequency resource are the network equipment at the second Determined from Y sub-bands included in the second frequency resource in a time unit, the second frequency resource is the downlink frequency resource allocated by the network device to the terminal device, and the Y sub-bands are included in the X sub-bands, and the second frequency resource corresponds to one wideband channel state information CSI, where X≥Y≥2, Y>Z≥1, and X, Y, and Z are all integers; the terminal device according to the The first frequency resource determines the broadband CSI; the terminal device sends the broadband CSI to the network device in a second time unit. The embodiment of the present application can solve the problem of how the terminal equipment reports the CSI under the condition that the downlink frequency resource changes dynamically.

Description

technical field [0001] The present application relates to the field of network communication, in particular to a method for measuring channel state information and related equipment. Background technique [0002] In order to assist the network device in effective management of the wireless communication system, the user equipment periodically and / or aperiodically reports current channel state information to the network device. In the existing LTE / LTE-A system, the user equipment (User Equipment, UE) will periodically or aperiodically feed back channel state information (Channel State Information, CSI) measurement information according to the configuration of the eNB, so that the eNB can obtain the UE's downlink channel condition. For example, in the LTE system, the CSI includes subband channel quality indicator (Channel Quality Indicator, CQI), precoding indicator (Pre-coding Matrix Indicator, PMI), rank indicator (Rank Indicator, RI) and so on. For the fifth generation (5...
