摘要： A method for transmitting signals for interference randomization is disclosed. The method for transmitting signals includes spreading the transmission signals using a plurality of orthogonal codes and transmitting the transmission signals spread by the plurality of orthogonal codes by a spatial frequency block coding (SFBC) or spatial time block coding (STBC) scheme. Among the plurality of orthogonal codes, codes of which mutual interferences are equal to or greater than a predetermined threshold are grouped to the same group, and orthogonal codes belonging to different groups are used for the spreading of the signals which are transmitted at the same timing. Accordingly, it is possible to realize interference randomization.

The method involves: generating a MIMO packet containing at least one set of spatial streams transmitted to each of one or more receivers, wherein each set of spatial streams is encoded on the basis of one of two encoding schemes; transmitting first control information containing a MIMO indicator and a first modulation and coding scheme (MCS) field, wherein said MIMO indicator indicates whether the MIMO packet is for single user (SU) MIMO or multi-user (MU) MIMO, wherein said first MCS field indicates the MCS used for the MIMO packet if the MIMO packet is for SU MIMO transmission, and indicates encoding schemes applied to each set of spatial streams if the MIMO packet is for MU MIMO transmission; and transmitting the MIMO packet to least one receiver. Said two encoding schemes are a low-density parity check (LDPC) encoding scheme and a binary convolution coding (BCC) scheme.
