Abstract  MAC lies in the lowest sublayer in the data linker layer, it plays very important role in the high speed mobile telecommunication system. This paper introduces the Medium Access  Control(MAC) procedure in brief, and proposes a scheme to realize the management of Resource Unit in the TD-SCDMA system, and gives the main MSC of the scheme .
