Abstract  Abstract

A method for transmitting a signal is provided, the method comprises the steps of: generating a control signal; generating modulation symbols by modulating the control signal according to a binary phase shift keying , BPSK, modulation scheme; layer mapping the modulation symbols to corresponding layers; precoding the modulation symbols on corresponding layers and resource mapping the precoded modulation symbols on defined resources by using a space frequency block coding, SFBC, technique; and transmitting the precoded modulation symbols on the mapped resources through at least two antennas, wherein the SFBC is to encode a set of the modulation symbols on a set of subcarriers in consideration with the at least two antennas, wherein, the control signal is an ACK/NACK signal, wherein the modulation symbols are applied an orthogonal sequence with a spreading length of 2 or 4.
