SRS channel quality measurement method and device

The invention relates to the communication technology field, particularly relates to an SRS channel quality measurement method and a device and aims to solve a technical problem that a channel quality SNR value can not be accurately acquired in the prior art. The SRS channel quality measurement method comprises steps that according to present signal to noise ratios of terminals in a time domain channel power spectrum, an average signal to noise ratio is determined, a present signal to noise ratio of one terminal is determined according to the present noise threshold; according a corresponding relationship between the noise threshold and the average signal to noise ratio, a target noise threshold corresponding to the average signal to noise ratio is determined; according to the target noise threshold, a precise signal to noise ratio of each terminal is determined. Through the method, through dynamically adjusting the noise threshold, the precise signal to noise ratio of each terminal is re-determined according
