1. A communication method, comprising:
determining M-bit acknowledgment information to be sent in a target time unit, wherein the M-bit acknowledgment information is acknowledgment information for first downlink data, and the first downlink data is transmitted in a semi-persistent scheduling manner;
receiving second indication information, wherein the second indication information is used to indicate P1 time-frequency resource sets, P1 is a positive integer, and each time-frequency resource set comprises N time-frequency resources;
receiving third indication information, wherein the third indication information is used to indicate an index of a first time-frequency resource set in the P1 time-frequency resource sets;
determining, based on the index of the first time-frequency resource set, N time-frequency resources in the target time unit;
determining N acknowledgment codebooks, wherein the N acknowledgment codebooks are used to carry the M-bit acknowledgment information, wherein the N time-frequency resources are used to transmit the N acknowledgment codebooks, wherein both M and N are positive integers, and at least one of M and N is not 1; and
sending the N acknowledgment codebooks on the N time-frequency resources in the target time unit, wherein each time-frequency resource of the N time-frequency resources carries one of the N acknowledgment codebooks.
