  Abstract

In this paper, we propose a new modulation and coding scheme(MCS) level selection algorithm in TDD system that utilize block error rate as well as channel quality indicator(CQI). The conventional MCS selection is carried out with only CQI received from user and inappropriate MCS selection might be occurred due to inaccurate channel estimation and channel variation. To cope with channel variation, an adaptive MCS selection algorithm is proposed. As a result of simulation analysis, the proposed algorithm shows a better BLER performance and coverage to the target BLER successfully.
