Embodiment Construction

[0033] In the embodiment of the present invention, the network side configures the user equipment with a measurement information set determined according to a transmission point on a carrier that needs to be measured by the user equipment, where the measurement information set includes measurement information of at least one transmission point. Since the network side configures the transmission points on the carrier, the user equipment can report the channel information of multiple carriers and multiple transmission points to meet the requirements of CoMP transmission.

[0034] In the embodiment of the present invention, the user equipment performs CSI measurement according to the measurement information of the transmission point in the measurement information set received from the network side, and reports the obtained measurement information. Since the user equipment can report the channel information of the multi-carrier and multi-transmission point according to the configur...

Abstract

An embodiment of the present application relates to the technical field of wireless communications, in particular to a method, system and device for configuring and reporting measurement information, used to configure the channel information of multiple transmission points and multiple carriers, so that a user equipment (UE) is incapable of reporting the channel information of multiple transmission points and multiple carriers, thus satisfying the requirement for CoMP transmission. The method for configuring measurement information of the embodiment of the present application comprises: a network side determines a measurement information set according to the transmission point on the carrier required to be measured by the UE, the measurement information set comprises the measurement information of at least one transmission point; the network side configures the determined measurement information set for the UE. Because the network side configures the transmission point on the carrier, the UE can report the channel information of multiple carriers and multiple transmission points, thus satisfying the requirement for CoMP transmission.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, system and equipment for configuring and reporting measurement information. Background technique [0002] The coordinated multipoint transmission (Coordinated Multipoint Transmission / Reception, CoMP) technology refers to the cooperation between multiple geographically separated transmission points. Through cooperative transmission between multiple transmission points, the interference between different transmission points can be effectively reduced, and the throughput of the user equipment, especially the cell edge user equipment, can be improved. Downlink multi-point coordinated transmission technical solutions are mainly divided into two categories: cooperative scheduling / beamforming (CS / CB, cooperative scheduling / beamforming) and joint processing (Joint processing). [0003] Coordinated scheduling is to avoid or reduce mutual interference thro...
