Signaling transmission and reception in wireless communication systems

A method for wireless communication, comprising:

• determining at least one vector of modulation symbols to send by a subscriber station in at least one tile for a signaling value, one vector of modulation symbols in each tile, the vector of modulation symbols for each tile being orthogonal to at least one other vector of modulation symbols usable by at least one other subscriber station in the tile;
• mapping the modulation symbols in each of the at least one vector to multiple subcarriers in a different one of the at least one tile;
• and
• sending the mapped modulation symbols in the at least one tile to convey the signaling value.

An apparatus for wireless communication, comprising:

• means for determining at least one vector of modulation symbols to send by a subscriber station in at least one tile for a signaling value, one vector of modulation symbols in each tile, the vector of modulation symbols for each tile being orthogonal to at least one other vector of modulation symbols usable by at least one other subscriber station in the tile;
• means for mapping the modulation symbols in each of the at least one vector to multiple subcarriers in a different one of the at least one tile;
• and
• means for sending the mapped modulation symbols in the at least one tile to convey the signaling value.

A computer program product, comprising:

• a computer-readable medium comprising:
• code for causing at least one computer to determine at least one vector of modulation symbols to send by a subscriber station in at least one tile for a signaling value, one vector of modulation symbols in each tile, the vector of modulation symbols for each tile being orthogonal to at least one other vector of modulation symbols usable by at least one other subscriber station in the tile;
• code for causing at least one computer to map the modulation symbols in each of the at least one vector to multiple subcarriers in a different one of the at least one tile;
• and
• code for causing the at least one computer to send the mapped modulation symbols in the at least one tile to convey the signaling value.

A method for wireless communication, comprising:

• obtaining at least one vector of received symbols from at least one tile;
• processing the at least one vector of received symbols to determine a set of at least one vector of modulation symbols sent by each of multiple subscriber stations in the at least one tile;
• and
• determining a signaling value sent by each of the multiple subscriber stations based on the set of at least one vector of modulation symbols determined to have been sent by the subscriber station in the at least one tile.
