1. A method for channel estimation, performed by a terminal device, comprising:
performing channel estimation using all demodulation reference signals (DM-RSs) included in N continuous repeated control-resource sets (CORESETs), where N is a positive integer greater than 1;
wherein, the N continuous repeated CORESETs correspond to both of the same frequency domain resource and the same precoding matrix, the same precoding matrix is obtained by precoding on the N continuous CORESETs using a same precoder;
wherein, M CORESETs in the N continuous repeated CORESETs are continuous on a time domain and other N-M CORESETs and the M CORESETs are discontinuous on the time domain, where 1<M<N.
