Abstract

A data transmission method, an apparatus, and a storage medium are provided. The method includes: A first terminal device and a first network device determine N second gap (GAP) occasions based on M first GAP occasions, where the M first GAP occasions include the N second GAP occasions, the M first GAP occasions are periodic time domain positions that are of a first GAP and that are configured by a first network device, M is greater than N, and both M and N are positive integers. A first signal is not transmitted between the first terminal device and a second network device on the N second GAP occasions, to prevent all the configured M first GAP occasions from taking effect on the first terminal device, which results in the first GAP occupying a large quantity of resources, and therefore to reduce resource occupation of the GAP.
