Feed-forward control signaling and decoding schemes

A method for decoding parameter allocation information, the method comprising:nreceiving an index indicating selected data stream parameters;receiving an indication of a number of transmit antennas at a transmitter from which the data stream is transmitted;determining the selected parameters from the index based on the number of transmit antennas at the transmitter; andreceiving and processing data signals with a processor in accordance with the selected data stream parameters,wherein the determining further comprises selecting one of a plurality of conversion schemes to convert the index, wherein each of said conversion schemes is customized to a different number of transmit antennas,wherein the index is a bit sequence and the conversion schemes are tables, wherein each table relates a set of bit sequences having a fixed length with a different, corresponding set of data stream parameters and wherein the index denotes different data stream parameters in at least two of the tables, andwherein the transmitter is an advanced base station, wherein the tables include a first table directed to eight transmit antennas and a second table directed to four or two transmit antennas, and wherein the second table includes at least one specific index that signifies three total streams, an assignment of one or two pilot stream indices to a given user and a modulation scheme employed by an other user that is co-scheduled with the given user.
