Title:
SIGNAL TRANSMISSION METHOD, TERMINAL, NETWORK DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/175149
Kind Code:
A1
Abstract:
Embodiments of the present application provide a signal transmission method, a terminal, a network device, and a storage medium. The method comprises: receiving a plurality of first downlink signals; determining downlink receiving frequencies corresponding to the first downlink signals, and respectively determining, on the basis of the downlink receiving frequencies corresponding to the first downlink signals, transmission frequencies of uplink signals in association with the first downlink signals; and sending the uplink signals on the basis of the transmission frequencies of the uplink signals, wherein a frequency shift determined on the basis of the uplink signals in association with the first downlink signals is used for determining a transmission frequency of a second downlink signal. In the embodiments of the present application, a pre-compensation of a downlink Doppler frequency shift is performed by means of each transmission receiving point, and therefore, an error of channel estimation is reduced, and the performance of downlink transmission is improved.
