A method and apparatus of reducing interference in space frequency block coding (SFBC) communication are disclosed. SFBC encoding is performed on at least one pair of symbols. The symbols are assigned to subcarriers in accordance with a frequency assignment pattern assigned to a cell. Different frequency assignment patterns are assigned to neighboring cells. Cells in the network may be divided into a plurality of groups and a different frequency assignment pattern may be assigned to each group of cells. The frequency assignment pattern may be defined such that subcarriers mapped to a pair of symbols in one cell are interlaced to subcarriers mapped to a pair of symbols in a neighbor cell. Alternatively, the frequency assignment pattern may be defined such that subcarriers mapped to a pair of symbols in one cell are shifted in a neighbor cell.
A method of reducing interference in space frequency block coding (SFBC) communication, the method comprising:
The method of claim 7 wherein cells are divided into seven groups and one of seven different frequency assignment patterns is assigned to each group.
A method of reducing interference in space frequency block coding (SFBC) communication, the method comprising:
An apparatus for reducing interference in space frequency block coding (SFBC) communications, the apparatus comprising:
The apparatus of claim 17 wherein cells are divided into seven groups and one of seven different frequency assignment patterns is assigned to each group.
An apparatus of reducing interference in space frequency block coding (SFBC) communication, the apparatus comprising:
