The paper mainly researches on service scheduling algorithms for IEEE 802.16. Firstly, the paper researches the QoS mechanism of MAC from two sides, the management of service flow and QoS guarantee. The improved cross layer QoS framework is proposed for the shortcomings of the existing QoS framework. Secondly, service scheduling algorithms are also one of the key parts to realize QoS. The paper mainly...
In this paper, heterogeneous services in multiuser multiple-input multiple-output (MIMO)-Relay systems are investigated, where the relays work in amplify-and-forward mode. A utility based adaptive scheduling algorithm is proposed, which aims to maximize user satisfaction as well as system spectral efficiency. Joint optimal carriers and spatial subchannels allocation is considered based on the proposed...
In this paper, three centralized packet scheduling schemes with fairness-oriented feature are proposed for OFDMA multihop relaying networks, namely Greedy polling with novel starvation restrained (SR-GP), enhanced proportional fairness with SR (SR-EPF) and novel subcarrier pairing with hop balance (HB-SP) scheduling algorithms. SR-GP can bring better fairness than traditional throughput-oriented algorithms...
