CHAPTER The IEEE 802.16m Medium Access Control Common Part Sub-layer (Part I) INTRODUCTION This chapter describes the functional and operational aspects of IEEE 802.16m MAC Common Part Sub-layer (MAC CPS) on the control-plane. As shown in Figure 6-1, the MAC CPS provides an interface between the physical layer and higher protocol layers through PHY and MAC SAPs, respectively. The MAC CPS functions are classified into Radio Resource Control and Management (RRCM) and MAC functions. The soft classification of the MAC CPS into RRCM and MAC sub- layer does not require any SAP between the two classes of functions. The RRCM functions fully reside on the control-plane, whereas the MAC sub-layer functions reside on both control-plane and data-plane. The RRCM includes several functional blocks that are related to radi
