Patent ID: 8441999

Claim:
An adaptive modulation and coding method, comprising the following steps: a transmitting node selects punctured PRBs and normal PRBs to transmit downlink data; the transmitting node determines a Transport Block Size TBS and the number of total PRB pairs for transmission to a receiving node based on a carried service, the number of total PRB pairs being the summation of the number of the scheduled normal PRB pairs and the number of the punctured PRB pairs; the transmitting node schedules the downlink data for the receiving node based on the determined TBS, and transmits the number of the total used PRB pairs, location information and a Modulation and Coding Scheme MCS sequence number to the receiving node; the receiving node calculates the number of total resource based on the number of the total PRB pairs, the location information and the situation of each punctured PRB; the receiving node calculates the number of the normal PRB pairs after conversion based on the number of total resource, determines the TBS of the downlink data based on the calculated number of the normal PRB pairs after conversion and the TBS sequence number determined by the MCS sequence number.
