MAC Frame Processing

The role of the MAC layer is to build valid TDMA/TDD MAC frames. TDMA/TDD MAC constructs frames based on the information elements and their formats given earlier in this chapter. Three parallel running processes can be identified:

  • Scheduler

  • Transmission and reception process

  • Control information exchange between MAC entities

Scheduler is an algorithm that assigns the transmit and receive slots for MT, but its implementation is beyond the scope of the standard and this chapter. Its implementation is entirely up to the device manufacturer as long as all the rules given in the standard and described shortly in this chapter are followed.

Access Point

Before being able to start transmitting a MAC frame, the access point and the central ...
