Abstract

The present disclosure provides an uplink transmission scheduling method and apparatus, a device, and a storage medium. The method comprises: determining that an uplink transmission occupies a first time unit and a second time unit; and determining frequency domain resources occupied by the uplink transmission in the first time unit and/or the second time unit. The method of the present disclosure can prevent, as far as possible, uplink resources in a UL slot from being partitioned, and reduce excessive fragmentation of the uplink resources, thereby improving the system performance.
