FIELD: information technology.
SUBSTANCE: actual number of orthogonal frequency division multiplexing (OFDM) symbols, Nos, used for the shared data channel is determined. A modulation order for transmission of data on the shared data channel is increased when the actual number of OFDM symbols Nos is less than 11 and decreased when Nos is more than 11. A modulation and coding scheme field (Imcs ) of control information of the shared data channel can also be determined. If 0≤IMCs+11-Nos≤28, the modulation order is modified by using a coefficient (IMCs+11-Nos) in a standardised modulation scheme. If it is determined that IMCs+11-Nos<0, the modulation order is set to quadrature phase shift keying (QPSK). If it is determined that IMCs+11-Nos>28, the modulation order is set to 64 quadtrative amplitude modulation (64QAM).
EFFECT: efficiency of the modification algorithm when adjusting code rate.
