Abstract: The present application discloses a method of channel estimation based on precoding granularity of control resource set, which is applied to a user equipment with control resource set (CORESET) configured in a non-RRC manner. The method includes: determining precoding granularity according to a determination mode among a plurality of determination modes; performing channel estimation according to the precoding granularity. The plurality of determination modes includes: determining the precoding granularity according to a resource element group (REG) bindle size in frequency domain, determining the precoding granularity according to the number of consecutive resource blocks (RBs) in frequency domain of the CORESET, and determining the precoding granularity according to network configuration information. According to the present application, the precoding granularity of the control resource set configured in a non-RRC manner can be determined, so that the user equipment can determine the precoding granularity before the RRC connection is established, and then perform channel estimation.
