Method and device for generating simulated interference

Abstract

The embodiment of the invention discloses a method and a device for generating simulated interference, which are used for obtaining the simulated interference which is consistent with the interference characteristics of real user equipment, accordingly, the performances of systems in different circumstances can be objectively reflected, and a technological assessment effect and the efficiency are improved. The method comprises the steps of: setting one or a plurality of simulated load templates, respectively carrying out interference characteristic parameter configuration on the simulated load templates, and using one simulated load template to simulate one or one type of interference with the same interference characteristics; and utilizing interference characteristic parameters which are configured on the simulated load templates to generate the simulated interference, and if a plurality of simulated load templates are set, polling the interference which is simulated and generated by the simulated load templates in a time domain and / or a frequency domain.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for generating analog interference. Background technique [0002] The Long Term Evolution (LTE, Long Term Evolution) system supports Multiple-Input Multiple-Output (MIMO, Multiple-Input Multiple-Output) transmission. This technology increases the division of spatial dimensions on the basis of traditional time-domain and frequency-domain transmission, and provides downlink transmission Provides greater flexibility. The LTE physical layer protocol of the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) Release8 and Release9 provides multiple transmission technologies such as downlink open-loop transmit diversity, open-loop spatial multiplexing, closed-loop spatial multiplexing, and beamforming. To adapt to different system configurations, user equipment (UE, User Equipment) capabilities and channel environments. [0003] In ...

AI Technical Summary

Problems solved by technology

An existing method for generating analog interference is to use a single single-stream transmission scheme to generate analog interference, which is equivalent to only one interfering user equipment, or although there are multiple interfering user equipments, all interfering user equipments have unique interference characteristics, that is, only Single codeword, rank is equal to 1, interference has no directionality, and there are obvious differences between simulated interference and real user equipment interference, which makes it impossible to objectively evaluate the performance of commercial systems
