Abstract
This application provides a communication method and related apparatus. The method includes: generating a trigger frame; the trigger frame includes user information fields corresponding to one or more users, the one or more users including a first user using joint source channel coding; the first user corresponds to multiple user information fields, one user information field corresponding to the first user is used to indicate the first user's layer frequency domain resources in one source layer; or, the first user corresponds to one user information field, the one user information field corresponding to the first user is used to indicate the first user's total frequency domain resources in all source layers; sending the trigger frame to receive trigger-based physical layer protocol data units from the first user, the trigger-based physical layer protocol data units including jointly source channel coded data located in the first user's layer frequency domain resources, thereby realizing joint source channel coded transmission based on the trigger frame.
