METHOD, SYSTEM AND DEVICE FOR ADAPTIVE MODULATION AND CODING

摘要

An adaptive modulation and coding method is provided by the present invention, comprising: selecting punctured Physical Resource Blocks (PRBs) to transmit the downlink data for the User Equipment (UE); determining the Transport Block Size (TBS) and the number of punctured PRB pairs for transmission to the UE based on the borne service; scheduling and transmitting the downlink data for the UE based on the determined TBS, and transmitting the number of the used punctured PRB pairs and a Modulation and Coding Scheme (MCS) sequence number to the UE; and the UE converting the number of the punctured PRB pairs to the number of complete PRB pairs, determining the modulation mode and the TBS sequence number based on the MCS sequence number, and determining the TBS of the downlink data based on the number of the complete PRB pairs and the TBS sequence number. Through conversion from the number of punctured PRBs to the number of complete PRBs in the present invention, processing for the specific condition when downlink data are transmitted with punctured PRBs can be performed and implemented simply and efficiently, based on use of the existing adaptive processing and resources of the general subframes.
