1. A method for transmitting rank information at an access terminal, the method comprising:
encoding a spatial rank index using a prescribed coding scheme,
transmitting the rank information corresponding to the spatial rank index,
wherein the spatial rank index is encoded using a corresponding codeword of Table A according to the prescribed coding scheme,
TABLE A
 
  spatial rank index codeword
 
  0x0 (0, 0, 0, 0, 0, 0, 0, 0)
  0x1 (1, 0, 1, 0, 1, 1, 0, 1)
  0x2 (0, 1, 1, 1, 0, 0, 1, 1)
  0x3 (1, 1, 0, 1, 1, 1, 1, 0).
