Abstract
In order to improve efficiency of data transmission in a wireless transmission band under a condition in which both adaptive modulation scheme and FDD scheme are employed, and fixed rate signals and a variable rate signal are multiplex-transmitted, one wireless transmission device (_) multiplexes a plurality of fixed rate signals (FS_to n) and a variable rate signal (VS) to generate a frame (FR), and sends the frame (FR) to another wireless transmission device (_) through a wireless transmission path (CH). At this time, the device (_) includes, in the frame (FR), information (MN) relating to a number of multiplexed fixed rate signals. The device (_) multiplexes a plurality of fixed rate signals (FS_to n) and a variable rate signal (VS) to generate a frame (FR), and sends the frame (FR) to the device (_) through a wireless transmission path (CH) having a different frequency. At this time, the device (_) determines a number of multiplexed fixed rate signals in the frame (FR) according to the information (MN).
