Abstract
The present application relates to the field of wireless communications, and in particular to a method and device for determining a dynamic HARQ-ACK codebook, and same are used to solve the problem that the wrong dynamic HARQ-ACK codebook is determined due to the inaccuracy of a PDCCH monitoring occasion set determined at present. According to the embodiments of the present application, the method involves: determining a PDCCH monitoring occasion set according to the configured number of repeated PDSCH transmissions and/or the number (N=1) of repeated PDSCH transmissions, and the configured number of repeated PDSCH transmissions is greater than one; and determining a dynamic HARQ-ACK codebook according to the PDCCH monitoring occasion set.
