MAC Overview
The MAC is based on a dynamic TDMA/TDD scheme with centralized control. The MAC frame appears with a period of two milliseconds (ms). The allocation of resources is controlled by an AP or CC. It is assumed that one MAC entity with one instance is provided per AP or per mobile terminal (MT). The MAC IDs are also used to administer broadcast and multicast services. The relation between MAC entities is created by a MAC ID, which is unique in a radio cell. To control the allocation of resources, the AP or CC needs to know the state of its own buffers and of the buffers in the MT. Therefore, the MTs report their buffer states in Resource Request (RR) messages to the AP or CC. Using this mechanism, the MTs request for resources from the ...
