A method and system for constant-power loading for asymmetric antenna configurations. The sounding packet, the sounding bit in HT-SIG field, and the HT-LTF field in the PLCP protocol data unit (PPDU) are used to determine the number of transmit antennas and the number of data streams, wherein if the number of transmission streams is the same as the number of data streams, then a first set of power loading level (fixed uneven power loading) is applied, otherwise a second set of power loading level is applied. Alternatively, one additional bit in the HT-SIG filed of PLCP protocol data unit (PPDU) signaling field is used to signal the set of power loading level used.
