Introduction n Updated SDD didn’t specify the MCS table size for channel coding. n In this contribution, we compare different MCS table size in terms of system throughput. n 4 bits MCS table is taken from current AWD text. n 5 bits MCS table is generated based on the burst size table.

Performance comparison between 4 bits and 5 bits MCS table n 5 bits MCS table has 4. 3% gain of system throughput over 4 bits MCS table, and 3. 2% gain of user coverage over 4 bits MCS table 5 bits MCS table Gain System throughput 1. 85 1. 93 4. 3% User coverage 0. 03823 0. 03947 3. 2%
