Embodiments of the present invention disclose a communication method and a related apparatus, where the method includes: determining a primary communication path to a target transmitter according to a first sounding reference signal SRS when the first SRS is received, where the target transmitter is a transmitter that sends the first SRS; obtaining an identifier of a transmitter that performs communication by using the primary communication path, and determining a secondary communication path of a transmitter indicated by each identifier; and communicating with the transmitter according to the primary communication path and the secondary communication path. According to the present invention, communication between a receiver and a transmitter may be established based on the determined primary communication path and the determined secondary communication path, which effectively improves a system transmission capacity.
