Method for setting modulation and coding scheme in wireless ran system and apparatus supporting the same
First Claim
1. A method for receiving data by a receiving station by using a multi-user multiple input multiple output (MU-MIMO) in a wireless local area network system, the method comprising:
- receiving, via a transceiver in the receiving station, a physical layer convergence procedure (PLCP) protocol data unit (PPDU) from a transmitting station, the PPDU including a bundled interface field, a modulation and coding scheme (MCS) index field and a data field,wherein the bundled interface field indicates a number of a plurality of spatial streams allocated to the receiving station among a plurality of receiving stations, and indicates a total number of spatial streams allocated to the plurality of receiving stations that receive the PPDU, andwherein the MCS index field indicates a same MCS index used for modulating and coding the plurality of spatial streams allocated to the receiving station; and
demodulating and decoding, via a processor in the receiving station and by using an MCS scheme indicated by the MCS index field, the data field received via the plurality of spatial streams indicated by the bundled interface field.
