This page intentionally left blank CHAPTER The IEEE 802.16m Medium Access Control Common Part Sub-layer (Part II) INTRODUCTION This chapter describes the functional and operational aspects of the IEEE 802.16m MAC Common Part Sub-layer (MAC CPS) on the data-plane. As shown in Figure 7-1, 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 Network Layer CS SAP Radio Resource Service Specific Control and Convergence Management Sublayer MAC SAP MAC Sublayer Security Sublayer PHY SAP Physical Layer Control Plane Data Plane FIGURE 7-1 IEEE 802.16m data-plane MAC CPS functions Mobile WiMAX.

CHAPTER 7 The IEEE 802. 16m MAC CPS (Part II) the control-plane, whereas the MAC sub-layer functions reside on both control-plane and data- plane [3]. The control-plane part of the MAC sub-layer includes functional blocks which are related to the physical layer and link control such as: Physical Layer Control; Control Signaling; Sleep Mode Management; Scheduling and Resource Multiplexing; Multi-Radio Coexis
