<p>The present invention relates to information transmission by a base station comprising the steps of: scrambling and performing quadrature phase-shift keying (QPSK) modulation, layer mapping, and precoding on one physical broadcast channel (PBCH) transmission bit block comprising bits the number of which corresponds to the number (Mbit) of coded bits to be transmitted in a PBCH; and, with there being at least one radio frame having the radio frame index n f wherein n f mod4 = 0 and four consecutive radio frames including said radio frame, mapping each bit of the precoded PBCH transmission bit block by increasing the frequency index k, OFDM symbol index, and radio frame index n f in ascending order from subframe #0 or a predetermined slot in subframe #0 of the four radio frames, with respect to resource elements (k, l), which have not been allocated for reference signal transmission, among complex symbol blocks (y (P) (0),..., and y (P) (M symb -1)) in respective antenna ports.</p> |
