Problems solved by technology

When the neighbor base station uses ABS, the serving base station may mistakenly think that the RSRQ of the neighbor base station is high, and handover by mistake
[0005] The 3rd Generation Partnership Project (3GPP for short) will propose solutions to the above problems for LTE-A user equipment, but LTE user equipment cannot use this solution

Embodiment Construction

[0029] figure 1 It is a schematic diagram of a wireless signal quality correction device 100 according to an embodiment of the present disclosure. The wireless signal quality correction apparatus 100 may be a serving base station of the user equipment 170. The user equipment 170 can detect wireless signals of the serving base station 100 and neighboring base stations 180. The serving base station 100 and the neighboring base station 180 support LTE and LTE-A. The user equipment 170 may be a mobile communication device supporting LTE.

[0030] The wireless signal quality correction device 100 includes an abnormality detector 120, a quality adjuster 140, and a handover function unit 160. The abnormality detector 120, the quality adjuster 140, and the handover function module 160 may be hardware or software. The abnormality detector 120 includes a signal monitor 122 and an ABS detector 124. The quality adjuster 140 includes a signal corrector 142 and a quality generator 144. Th...

Abstract

A method and an apparatus for correcting wireless signal quality are provided. The apparatus includes an abnormality detector and a quality adjuster. The abnormality detector collects multiple measurement values reported by a user equipment (UE), calculates a variation degree value according to the measurement values, and compares the variation degree value with a predetermined threshold value. The measurement values are generated by the UE when the UE measures the wireless signal quality of an evolved node B. The measurement values include a first reference signal receiving quality (RSRQ) of the evolved node B. When the variation degree value is larger than the predetermined threshold value, the quality adjuster corrects the first RSRQ based on the measurement values to generate a second RSRQ of the evolved node B.

Description

Technical field [0001] The present disclosure relates to a method and device for correcting wireless signal quality, and in particular to a method and device for correcting reference signal receiving quality (referred to as RSRQ hereinafter). Background technique [0002] Long Term Evolution (Long Term Evolution, LTE for short) and Long Term Evolution Advanced (LTE-Advanced, LTE-A for short) are the next generation of wireless communication networks. LTE-A's new enhanced inter-cell interference coordination (enhanced Inter-cell) under the heterogeneous network (Heterogeneous Network, HetNet) deployed in a mixed deployment of high-power large base stations (eNB, meaning Evolved Node B) and low-power base stations Interference Coordination, abbreviated as eICIC, is a mechanism that can solve co-frequency interference between high-power and low-power base stations in a heterogeneous network. The principle is that high-power and low-power base stations can use almost blank subframes ...
