Abstract: Example frequency domain resource allocation methods and apparatus are described. One example method includes determining M frequency domain resources according to a predetermined frequency domain resource allocation rule, and performing communication on one or more of the M frequency domain resources. Any two of the M frequency domain resources do not overlap. Each of the M frequency domain resources is associated with one piece of quasi-colocation (QCL) information, and any two of the M frequency domain resources are associated with different QCL information.
