Abstract
In a communication method, a terminal device obtains a code division multiplexing capability of a physical resource of an uplink control channel, where the code division multiplexing capability is a length of orthogonal cover codes for multiplexing terminal devices in a code division manner on a unit resource in the physical resource of the uplink control channel, and the code division multiplexing capability configured by higher layer signaling. The terminal device further determines the physical resource based on the code division multiplexing capability, and sends uplink control information on the physical resource.
