Title:
FREQUENCY COMPENSATION METHOD AND APPARATUS, NETWORK-SIDE DEVICE, TERMINAL, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/175146
Kind Code:
A1
Abstract:
Embodiments of the present application provide a frequency compensation method and apparatus, a network-side device, a terminal, and a storage medium. The method comprises: receiving, by using one or more first TRPs, a first uplink signal used for frequency compensation and sent by the terminal; determining, by using the first uplink signal, a frequency compensation value separately corresponding to at least one first TRP; and determining, according to the frequency compensation value separately corresponding to the at least one first TRP, transmission frequency of at least one first TRP separately used for downlink transmission. Therefore, the embodiments of the present application implement the frequency compensation for the at least one first TRP during downlink transmission, effectively eliminate a Doppler spread of a terminal side, and further improve the performance of downlink transmission.
