FIELD: mobile communication systems. SUBSTANCE: channel coding and multiplexing device wherein plurality of transport channel frames are converted into plurality of physical channel frames has rows of radio frame matching units, their number being equal to or greater than number of transport channels; each row of matching units has radio-frame segmenting device and functions to segment each frame of transport channel that may have different transmission time intervals in radio frame. Multiplexer functions to multiplex radio frames to form sequential data frame. EFFECT: enhanced coding precision and data transfer speed. 24 cl, 8 dwg
