Abstract:

The MAC protocol applied for OFDMA system — Centralized Mini-slot Packet Reservation Multiple Access (CMPRMA) protocol is proposed. The proposed protocol divides the radio resources into mini-time-frequency blocks, which are the basic transmission units. As the control center, Base station controls the resource allocation dynamically for users’ access and data transmission. It not only inherits the advantages of MPRMA prototype, which can support real-time traffic well, but also can supply the resource reservation scheme for data traffic,and can support efficient transmission for multi-users and multi-traffics.

Key words: OFDMA, Centralized Mini-slot Packet Reservation Multiple Access protocol, mini-time-frequency block
