Abstract

An uplink frequency selection scheduling method and apparatus, and a storage medium. The uplink frequency selection scheduling method comprises: acquiring a first uplink signal-to-interference-plus-noise ratio (SINR) of each frequency-domain resource block (RB) that is measured on the basis of a sounding reference signal (SRS), and a second uplink SINR of each RB that is measured on the basis of a demodulation reference signal (DMRS); obtaining uplink channel quality data of the RB on the basis of the first uplink SINR and the second uplink SINR; and determining a frequency selection threshold on the basis of the uplink channel quality data, and determining a target RB on the basis of the uplink channel quality data and the frequency selection threshold.
