Problems solved by technology

[0004] However, in the prior art, the macro base station (the first base station) adopts a scheme of uniformly configuring the CRE bias value for the micro cell (the second base station) within the coverage area, so that when the CRE bias value is small, it can be offloaded to the UE of the second base station ( User equipment, user equipment) is less, when the CRE bias value is larger, the UE drops more calls

Abstract

The invention discloses a method and a device for determining a communication extension bias boundary, and relates to the technical filed of communication. Different CRE bias upper bounds are set by a first base station according to different second base stations, so that the number of user equipment (UE) unloaded to the second base stations can be increased, and call drop rate of the UE is reduced. Signal to interference plus noise ratio (SINP) of the user equipment in a coverage area of the second base stations is accounted and determined, community extension bias boundary upper bounds of the second base stations are calculated according to a first SINR and are sent to the first base station or a network management system. The method and the device are suitable for determining the community extension bias boundary.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for determining a cell extension offset boundary. Background technique [0002] In a wireless communication system, using a heterogeneous network for data transmission can improve performance requirements of LTE (Longterm evolution, long term evolution) and / or LTE-A (Advanced long term evolution, advanced long term evolution). A heterogeneous network is to deploy base stations of different types or standards in a homogeneous network, which can enhance network coverage and performance. [0003] In order to improve the spectrum utilization efficiency of the system and increase the network capacity, in the heterogeneous network, by adjusting the CRE bias (Cell Range Expansion bias, cell expansion bias) value of the micro cell, the cell coverage expansion of the micro cell in the macro cell is realized, so as to The UE in the macro cell is further ...
