01 Dec 2011TL;DR: Simulations results with H.264/AVC coded video sequences show that significant gains could be observed by the proposed two-layer scheduling scheme in terms of spectrum efficiency, QoS of packet loss, and video quality while maintaining the fairness among the streams.
Abstract: Given that statistical multiplexing of video streams is employed in enhanced Multimedia Broadcast/Multicast Service (e-MBMS), we address the issue of scheduling across the streams towards Advanced-Long Term Evolution (LTE-A) system, in order to improve the quality of service (QoS) performances. In this paper, the optimization problem of scheduling and resource allocation for separate streams is first formulated. With practical considerations including the terminal power consumption and MBMS over a Single Frequency Network (MBSFN) operation, hence a suboptimum QoS-aware two-layer scheduling scheme is proposed to allocate resources among the streams. By separating streaming scheduling and packet sorting, the scheduler is aware of queue state information, fairness among the streams, and the frame weight. Simulations results with H.264/AVC coded video sequences show that significant gains could be observed by our scheme in terms of spectrum efficiency, QoS of packet loss, and video quality while maintaining the fairness among the streams.

01 Oct 2016TL;DR: The main characteristics of this new release of standard version “Release 13”, referred by experts as LTE-Advanced Pro or ‘4.5G’, and the planned roadmap to reach the final target of 5G are discussed.
Abstract: With the unceasing increase of the mobile data traffic, network operators are forced to improve the performance of their networks. The traffic explosion is intensified by the recent deployment of Long Term Evolution (LTE) networks. However, operators cannot opt for deploying more cells, as this will increase their financial investments. Operators are seeking for mobile technologies with higher spectral efficiency in bit/s/Hz, cloud-based intelligent architecture, etc. The operators' requirements are under investigation by 3rd Generation Partnership Project (3GPP) to develop the next mobile generation (5G), which should match the technical requirements and economic feasibility. The road to 5G is still not clear. Therefore, telecom players marked a next step towards 5G by issuing new standard version “Release 13”, referred by experts as LTE-Advanced Pro or ‘4.5G’. In this paper, we discuss the main characteristics of this new release and the planned roadmap to reach the final target of 5G.

01 Sep 2009TL;DR: Single user beamforming with rank adaptation and multi-user beamforming using block diagonal algorithm are studied to make full use of the spatial multiplexing gain and a novel smart power allocation and power control scheme is proposed for multi-users beamforming usage.
Abstract: For the channel reciprocity property, Eigen-based Beamforming (EBB) has been attracting more and more attentions in LTE-Advanced system. In this paper, single user beamforming with rank adaptation and multi-user beamforming using block diagonal algorithm are studied to make full use of the spatial multiplexing gain. In addition, power control and power allocation are discussed to improve the performance. At last, a novel smart power allocation and power control scheme had been proposed for multi-user beamforming usage. The simulation results showed that the proposed schemes have got significant gain over traditional methods. All the results are provided using dynamic system level simulator based on LTE-Advanced.
