Claim 5:
6. An apparatus, comprising: one or more processors, and one or more computer-readable storage media storing program instructions; wherein, when executed by the one or more processors, the program instructions cause the apparatus to:
receive first downlink control information, wherein the first downlink control information is used to schedule an uplink shared channel, the first downlink control information comprises first indication information and second indication information, the first indication information indicates that the uplink shared channel is used to send uplink control information but is not used to send data and the second indication information indicates a modulation and coding scheme index of the uplink shared channel;
determine, based on the first indication information, that the uplink shared channel is used to send uplink control information without data;
determine, based on the modulation and coding scheme index in the second indication information, a first code rate of the uplink shared channel and a modulation order of the uplink shared channel; and
send first uplink control information through the uplink shared channel, wherein the first uplink control information comprises a hybrid automatic repeat request-acknowledgement, wherein
a total quantity of resource elements in the uplink shared channel that are used to carry the first uplink control information is M, and a quantity of resource elements in the uplink shared channel that are used to carry the hybrid automatic repeat request-acknowledgement is a minimum value of a first quantity and the total quantity M, wherein the first quantity is equal to a round-up value of a ratio of a first product to a second product, wherein the first product is a product of a payload size of the hybrid automatic repeat request-acknowledgement and a code rate compensation parameter of the hybrid automatic repeat request-acknowledgement, and the second product is a product of the first code rate and the modulation order.
