Method and apparatus for transceiving a MIMO packet in a wireless LAN system

摘要

The present invention relates to a method in which a transmitter transmits a multiple input multiple output (MIMO) packet in a wireless LAN system. 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.
