In IEEE 802.16j relay networks, wireless communications are carried out based on TDMA where the wireless network resources are divided into multiple time slots and they are assigned to wireless links between relay nodes as transmission opportunities. The network performance is improved by decreasing the total number of different time slots assigned to all links in a single scheduling cycle, because it brings the increase in the transmission opportunities of the links per unit time. Although it can be achieved when multiple links utilize the same time slot, the capacity of such links is degraded due to the radio interference.
