It should be noted that if the base station receives more than
C successful reservation packets in a frame, it can send only C
channel allocation packets in the frame corresponding to the first
C reservation packets. In this case, the base station has two alternatives
regarding the treatment for the rest of the successful
reservations. One is that the base station gives up the channel
allocation for the rest of the reservations; then, the reservations
must be made again in a future frame by the corresponding terminals.
The other is that the base station transmits channel
allocation packets for the rest of the reservations in the subsequent
frames. In this paper, we study the former scheme
