FIELD: communication equipment.
SUBSTANCE: invention relates to communication engineering and can be used in wireless communication systems. For this, in the device, control part (209) controls the ZC sequence, which is used during the primary expansion in expansion part (214), and the Walsh sequence, which is used in the secondary expansion in expansion part (217), to allow a very small cyclic shift interval of the ZC sequence to absorb interference components, remaining in the response signal; extension part (214) uses the ZC sequence established by control part (209) for the primary expansion of the response signal; and expansion part (217) uses the Walsh sequence established by control part (209) for the secondary expansion of the response signal to which the CP prefix was added.
EFFECT: technical result consists in improving the quality of the separation characteristic in multiplexing with code compression of the response signal.
