Abstract
Certain aspects of the present disclosure provide techniques and apparatus for frequency interleaving for use with 80 MHz transmissions, such as those in the IEEE 802.11ac amendment to the IEEE 802.11 standard. According to certain aspects, frequency interleaving spatial streams for transmissions on channels having widths of about 80 MHz may comprise using an interleaving depth of 26. The number of frequency rotations may be 58 (or 29) for up to four (or up to eight) spatial streams. According to certain aspects, frequency interleaving up to eight (or up to four) spatial streams for transmission on channels having widths of about 80 MHz may comprise performing frequency rotation for each of the spatial streams based on a frequency rotation index=[0 4 2 6 1 5 3 7] (or=[0 2 1 3]).
