FIELD: radio engineering, communication.
SUBSTANCE: wireless transmission device multiplexes a plurality of fixed rate signals and a variable rate signal to generate a frame (FR1), and sends the frame to another wireless transmission device via a wireless transmission path. At this time, the first device includes, in the frame (FR1), information (MN) relating to a number of multiplexed fixed rate signals. The second device multiplexes a plurality of fixed rate signals and a variable rate signal to generate a frame (FR2), and sends the frame (FR2) to the second device via a wireless transmission path (CH2) having a different frequency. At this time, the second device determines the number of multiplexed fixed rate signals in the frame (FR2) according to the information (MN).
EFFECT: higher efficiency of transmitting data in a wireless transmission band under conditions where an adaptive modulation scheme and a FDD scheme are used, and fixed rate signals and a variable rate signal are transmitted with multiplexing.
