1. A method for feedback information processing, comprising:
receiving, by a terminal device, signaling that is used to determine at least one carrier of N carriers, wherein N is a positive integer; and
generating, by the terminal device, a feedback information codebook, wherein the feedback information codebook comprises feedback information corresponding to all hybrid automatic repeat request (HARQ) processes within the at least one carrier of the N carriers,
wherein the signaling comprises carrier indication information, an indication range of the carrier indication information comprises N−1 carriers, and the N−1 carriers refer to all carriers other than a first carrier in the N carriers,
wherein the first carrier comprises one of the following:
a carrier used for receiving the signaling;
a carrier corresponding to a control resource set (COREST) used for receiving the signaling, wherein downlink control information (DCI) transmitted in the COREST is configured to schedule a physical channel in the first carrier;
a carrier corresponding to a search space used for receiving the signaling, wherein DCI transmitted in the search space is configured to schedule a physical channel in the first carrier; and
a carrier receiving a first downlink channel, wherein the first downlink channel is a downlink channel that is scheduled for transmission by the signaling,
wherein the feedback information codebook further comprises feedback information corresponding to a HARQ process carried by a physical downlink channel received within a first time period, and
wherein the first time period is determined according to a transmission position of the signaling.
