发明名称 SYSTEM AND METHOD OF MODULATION AND CODING SCHEME ADJUSTMENT FOR A LTE SHARED DATA CHANNEL
摘要 A system, method and node for modulation and coding scheme adjustment for a Long Term Evolution (LTE) shared Data Channel. The method determines an actual number of orthogonal frequency division multiplexing (OFDM) symbols, NOS 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 Nos is less than 11 and decreased when NOS 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 o = IMCS +11- NOS = 28, the modulation order is modified by utilizing a factor of (IMCS + 11 - NOS ) in a standardized modulation scheme. If it is determined that IMCS + 11 - NOS < o, the modulation order is set to Quadrature Phase Shift Keying (QPSK). If it is determined that IMCS + 11 - NOS > 28, the modulation order is set to 64 Quadtrative Amplitude Modulation (64QAM).
