2. Introduction
Bit labeling for BPSK, QPSK, 16 QAM, and 64 QAM defined in standard has the following characeritics:
Independent Gray coding on I & Q axis
I bits followed by Q bits
Most negative symbol value corresponds to all 0’s
Need to specify mapping for 256 QAM
We propose simply to extrapolate from already defined constellations in n
4 bit Gray coding for each dimension

4. Straw Poll
Do you accept the 256 QAM constellation mapping as shown on Slide 3 of this document to be included into the Specification Framework document 11-09/0992 ?

5. Motion
Move to accept the 256 QAM constellation mapping as shown on Slide 3 of this document to be included into the Specification Framework document 11-09/0992 .
