Abstract

The application provides a time delay compensation method, device, apparatus and storage medium. After a UE or a network device acquires a wireless network resource, the UE or the network device determines a time difference of data transmission and reception through the wireless network resource. Based on the time difference corresponding to the UE and the time difference corresponding to the network device, a transmission time delay compensation value of data transmission between the UE and the network device can be determined. According to the transmission time delay compensation value, the UE or the network device can perform time delay compensation processing between the UE and the network device. Compared with the prior art, the application helps to improve the accuracy of time synchronization error between the UE and the network device.
