Abstract: This application provides a communication method and apparatus, and a computer-readable storage medium. The communication method includes: receiving first indication information from a network device, where the first indication information is used to determine a frequency-domain position to which a physical uplink control channel (PUCCH) resource is mapped; and sending information to the network device in first duration by using the PUCCH resource, where frequency-domain positions to which the PUCCH resource is mapped in at least two consecutive time units in the first duration are different. According to the technical solutions provided in this application, a limitation of a frequency-hopping gain of the PUCCH resource can be reduced, and coverage can be enhanced.

Abstract: This application provides an information transmission method, an apparatus, and a system, to improve coverage and transmission reliability that are of uplink control information UCI, thereby improving communication efficiency. In the method, after determining UCI, a terminal device sends the uplink control information on N frequency domain resource units, where N is a positive integer greater than 1. Based on this solution, when a power spectral density is determined, a larger quantity of frequency domain resource units may indicate a higher transmit power, so that coverage of the UCI can be increased. In addition, when a quantity of bits of the UCI is small, rate matching may be performed on the N frequency domain resource units, to reduce a code rate, so that transmission reliability is improved.
