Abstract

The invention discloses a frequency isolation method comprising: obtaining the data of S measurement reports (MR) of the original system of the current grid; and using the data of each MR as a sampling point wherein S is a positive integer; according to preset rules, carrying out identification to each interfering cell in the total samples; making statistics on the identification condition of each interfering cell; and based on the statistical result of each interfering cell and according to the preset strategy, determining whether each interfering cell needs to be subjected to frequency isolation from a new system cell or not and the frequency isolation value. The invention also discloses a frequency isolation apparatus. With the technical schemes of the invention, it is possible to clearly indicate the choice of a frequency isolation cell and the configuration of the frequency isolation magnitude, simplify the configured network planning procedure and effectively ensure the performances of two systems.

Description

technical field

[0001] The invention relates to frequency isolation technology in the field of wireless communication, in particular to a frequency isolation method and device. Background technique

[0002] With the development of wireless communication technologies, more and more operators upgrade and utilize frequency resources originally occupied by systems with lower spectral efficiency (that is, frequency refarming), and apply these frequency resources to standards with higher spectral efficiency. In the process of frequency refarming, because the original system is still in use, only part of the frequency can be used for the new system. When part of the frequency of the original system is refarmed to the new system, the original system and the new system may occupy adjacent frequencies, so Frequency isolation needs to be established.

[0003] In general, due to the out-of-band attenuation of the transmitting and receiving filters, the impact of adjacent channel interf...
