Abstract
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 carried service; scheduling 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 normal PRB pairs, determining the modulation scheme 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 normal PRB pairs and the TBS sequence number. The specific condition when downlink data are transmitted with punctured PRBs may be performed in the present invention on the basis of utilizing the existing resources and adaptive processing of the general subframes by performing conversion between the number of punctured PRBs and the number of normal PRBs in scheduling resource for the UE with the N…
