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

[0062] 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 SINR value include:

[0063] (1) Compare the obtained channel quality SINR value with the preset channel quality discrimination threshold, and when the channel quality SINR value is greater than or equal to the channel quality discrimination threshold, divide the corresponding user equipment UE into a suspected cell center user CCU , otherwise, classify the corresponding user equipment UE as a suspected cell edge user CEU;

[0064] (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 user equipment UEs to obtain the number of CEUs of cell edge users, a...

Abstract

The invention discloses a method and device for dividing edge users in an LTE system, and a base station thereof. The method includes: the base station acquires channel quality information of user equipment UE by measuring a sounding reference signal SRS; the base station obtains channel quality information according to the channel quality information An attribute discrimination parameter used to classify the attributes of the corresponding user equipment UE is obtained, and attribute classification is performed on the corresponding user equipment UE according to the attribute discrimination parameter. The present invention can greatly reduce the number of reporting times of inter-cell interference coordination measurement reports, so as to achieve the effect of saving air interface wireless resources, and at the same time, because the user equipment UE does not need to report frequent measurement reports, it can save the power of the user equipment UE 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 uplink 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 classif...
