Abstract
A novel reservation Aloha scheme is presented for OFDMA systems. The proposed scheme is based on two dimensional reservation in time and frequency. The proposed approach is compared to other OFDMA extensions of reservation Aloha. The proposed scheme is shown to be superior in terms of increasing sum-rate, reducing the number of users in outage, and reducing the collision probability in the reservation phase.
