Claim of US Patent No. 9,060,363

1. An adaptive modulation and coding method, comprising:
selecting by a base station NodeB, special subframes for transmitting downlink data to user equipment UE, Physical Resource
Blocks PRBs in the special subframes being punctured PRBs;

scheduling and transmitting by the NodeB;
scheduling the downlink data based on a determined Transport Block Size TBS;
transmitting a first number representing quantity of the used punctured PRB pairs, and a Modulation and Coding Scheme MCS
sequence number to the UE;

converting by the UE the first number of the punctured PRB pairs to a second number representing quantity of normal PRB pairs;
determining by the UE, a modulation scheme and a TBS sequence number based on the MCS sequence number; and
determining by the UE, the TBS of the downlink data based on the second number of the normal PRB pairs and the TBS sequence
number.
