Abstract	Scheduling is a fundamental component in resource (bandwidth and power) management in NG wireless networks and plays the main role in providing QoS requirements such as delay, throughput and packet loss for different classes of service in 802.16d networks. In this paper we propose a novel scheduling algorithm Strict Priority Based Adaptive modulation and Coding (SP_AMC_Based) that can grantee QoS between different connections belong to different users by the means of cross layer design between MAC and PHY layers in the process of bandwidth allocation to the contrary of most existing protocols that are base solely on MAC layer. Without loss of generality, the protocol serves a number of users with different connections (flows) that have different QoS requirements. The scheduler considers user current channel condition, connection QoS requirement and packet delay to select a user to be scheduled. The proposed scheduling algorithm is investigated through simulation and performance comparison with WFQ[1] scheduler. The results show a better performance of the proposed scheduler compared with WFQ algorithm.
