Claim of US Patent No. 9,596,052

1. A method for transmitting Modulation and Coding Scheme (MCS) indication information, wherein the method comprises:
determining, by a network side, an MCS level corresponding to a channel scheduled by the network side for a UE, according
to channel quality and a first MCS table;

notifying, by the network side, the UE of the determined MCS level in first indication information to instruct the UE to determine
a modulation scheme and a code rate for the channel according to the MCS level;

wherein there are at least corresponding entries of MCS indexes and Transport Block Size (TBS) indexes corresponding to modulation
schemes at higher modulation orders than 6 in the first MCS table, and there is a one-to-one correspondence between MCS indexes
and MCS levels;

the method further comprising:
determining, by the network side, if there is also a second MCS table which is an MCS table specified in the 3GPP LTE Rel-11
and earlier releases;

if the network side determines that there is also a second MCS table which is an MCS table specified in the 3GPP LTE Rel-11
and earlier releases, then:

instructing the UE in second indication information to use the first MCS table or the second MCS table when the UE is determining
the modulation scheme and the code rate for the channel according to the notified MCS level.
