Problems solved by technology

It can be seen that the transmission of RRC signaling needs to consume air interface radio resources. When the current base station specifically determines whether the UE belongs to the CEU or the CCU, the general method is to set a discrimination threshold for the reported measurement quantity. When the set discrimination threshold is lower than the handover When the actual threshold is set, the UE will frequently report ICIC measurement reports, resulting in a large waste of radio resources on the air interface, and will also greatly consume the power resources of the UE

Embodiment approach

[0063] In another more preferred implementation manner, the processing steps for the base station to classify the attributes of the corresponding user equipment UE according to the channel quality indication level CQI include:

[0064] (1) Compare the channel quality indication level CQI reported by the corresponding user equipment UE with the preset channel quality judgment threshold, and when the channel quality indication level CQI is greater than or equal to the channel quality judgment threshold, divide the corresponding user equipment UE into It is a suspected cell center user CCU, otherwise, the corresponding user equipment UE is classified as a suspected cell edge user CEU;

[0065] (2) Calculate the proportion value of the CEUs of the suspected cell edge users, and when the proportion value is not 0, take the smaller one between it and the preset additional discrimination ratio threshold as the number of CEUs of the cell edge users multiplied by the total number of us...

Abstract

The invention discloses a method, a device and a base station for dividing limbic users in a long term evolution (LTE) system. The method comprises that user equipment (UE) obtains downlink channel quality information through measuring a cell reference signal (CRS) and reports the downlink channel quality information to the base station; the base station obtains an attribute distinguishing parameter used for dividing corresponding UE attributes according to the channel quality information, and the base station divides attributes of the corresponding UE according to the attribute distinguishing parameter. By means of the method, the device and the base station, reporting times of interference coordination measuring reports among cells can be greatly reduced, and therefore empty-port wireless resources can be saved, and meanwhile, due to the fact that the UE does not need to report the measuring reports frequently, power of the UE can be saved to a certain extent.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular, to a method, a device and a base station for dividing edge users by using downlink measurement quantities in an LTE (Long Term Evolution, Long Term Evolution) system. Background technique [0002] The LTE system regards improving and improving the performance of cell edge users as one of the main goals, and has proposed many special technical solutions for how to improve the performance of cell edge UE (User Equipment, user equipment), among which ICIC (Inter-Cell Interference Coordination , inter-cell interference coordination) technology is introduced to reduce co-channel interference between adjacent cells, thereby improving the throughput of edge users and user satisfaction performance. [0003] The ICIC supported by the LTE system is very flexible and diverse. According to different consideration angles and technical characteristics, there are many class...
