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...
Cooperative relaying transmission is proved to be a feasible method for QoS guaranteed and dead-spot coverage. In this paper, the power and frame allocation schemes are proposed for TDD-based cooperative relaying system. Based on the related work on adaptive frame allocation (FA), the optimal power allocation (PA) is deduced for compress-and-forward (CF) relaying, and the optimal PA and FA schemes...
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...
Multiprocessor architectures are becoming more attractive for embedded systems, and also for multimedia embedded systems. In multimedia embedded systems, there exist both hard real-time tasks and multimedia stream with QoS guarantee. In this context, researched on integrated schedule of both hard real-time tasks and streams are urgent affairs. This paper analyzes the shortcomings of the current approach...
The cooperative cellular relaying network is expected to achieve the higher capacity and enlarge the coverage. In this paper, a novel cost-aware handover decision algorithm (CHDA) for cooperative cellular relaying networks is proposed. Two cost functions, namely the triggering and priority decision cost functions are exploited, which involves the signal transmission quality, the handover signaling...
