Adaptive modulation and coding method, system and device

摘要: The invention provides an adaptive modulation and coding method. method comprises the following steps that: a transmitting node transmits downlink data by using puncture physical resource block (PRB) complete PRB; determines transmission size TBS transmitted to receiving total number of PRB pairs for dispatching according carried services; dispatches adopted pairs, position information MCS sequence node; calculates number; converted calculated pairsand determined through number. Through method, all or part special conditions when can be processedby processing process conventional normal subframe, so that effects simpleness high efficiency are achieved.
