1. A method for feeding back HARQ-ACK information, comprising:
determining, by a terminal, when N carriers are configured, a second hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback resource based on a first HARQ-ACK feedback resource and the N carriers; and
transmitting, by the terminal, HARQ-ACK information based on the second HARQ-ACK feedback resource, wherein
the first HARQ-ACK feedback resource is determined according to a network indication, N≥2, and N is an integer;
wherein the determining, by the terminal, the second HARQ-ACK feedback resource based on the first HARQ-ACK feedback resource and the N carriers comprises:
determining, by the terminal, based on a first time, the second HARQ-ACK feedback resource on a first carrier set;
wherein the first time is determined based on the first HARQ-ACK feedback resource;
wherein the first time comprises a first HARQ-ACK feedback time or any time after the first HARQ-ACK feedback time, the first HARQ-ACK feedback time belongs to the first HARQ-ACK feedback resource, and the first carrier set is determined on the first time;
wherein after the determining, by the terminal, based on the first time, the second HARQ-ACK feedback resource on the first carrier set, the method further comprises:
determining, by the terminal, when the second HARQ-ACK feedback resource is not determined on the first carrier set, the second HARQ-ACK feedback resource on the first carrier set based on a second time, wherein
the second time is later than the first time;
wherein that the second HARQ-ACK feedback resource is not determined on the first carrier set comprises: a HARQ-ACK resource determined on the first carrier set conflicts with a downlink (DL) resource.
