RE: AWD comments / Area: Chapter 15.3.12(Channel coding) “Comments on AWD 15.3.12 channel coding”. Base Contribution: Purpose: Propose to be discussed and adopted by TGm for the use in Project 802.16m AWD.

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