<p>A SYSTEM, METHOD AND NODE FOR MODULATION AND CODING SCHEME ADJUSTMENT FOR A LONG TERM EVOLUTION (LTE) SHARED DATA CHANNEL. THE METHOD DETERMINES (200) AN ACTUAL NUMBER OF ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING, OFDM SYMBOLS, N OS UTILIZED FOR THE SHARED DATA CHANNEL. A MODULATION ORDER FOR TRANSMISSION OF DATA ON THE SHARED DATA CHANNEL IS INCREASED WHEN THE ACTUAL NUMBER OF OFDM SYMBOLS N OS IS LESS THAN 11 AND DECREASED WHEN N OS IS MORE THAN 11. A MODULATION AND CODING SCHEME FIELD (I MCS) OF A DOWNLINK CONTROL INFORMATION OF THE SHARED DATA CHANNEL MAY ALSO BE DETERMINED. IF 0 ? IMCS + 11 - N OS ? 28, THE MODULATION ORDER IS MODIFIED BY UTILIZING A FACTOR OF (I MCS + 11-N OS) IN A STANDARDIZED MODULATION SCHEME. IF IT IS DETERMINED THAT I MCS + 11 ? N OS < 0, THE MODULATION ORDER IS SET (208) TO QUADRATURE PHASE SHIFT KEYING, QPSK. IF IT IS DETERMINED THAT I MCS + 11 ? N OS > 28, THE MODULATION ORDER IS SET (210) TO 64 QUADRATIVE AMPLITUDE MODULATION, 64QAM.</p> |
