03 Apr 2016TL;DR: To reduce the complexity caused by a large number of co-scheduled users in 3DMU-MIMO, a simplified and high efficient 3D MU-M IMO scheduling algorithm is developed.
Abstract: In this paper, we investigate three-dimensional (3D) multi-user (MU) multiple-input multiple-output (MIMO) transmission for long term evolution advanced (LTE-A) downlink systems. We investigate some key techniques for 3D MU-MIMO to improve the performance of LTE-A systems, including rank and precoding matrix (PM) determination and user pairing. To reduce the complexity caused by a large number of co-scheduled users in 3D MU-MIMO, we develop a simplified and high efficient 3D MU-MIMO scheduling algorithm. The performance improvement of the proposed algorithm is demonstrated by system level simulation.

TL;DR: This paper proposes a reasonable and feasible ASIC design scheme and valid UVM (Universal Verification Methodology) verification platform from the perspective of studying the cell ID blind detection algorithm as well hardware implementation by balancing the fast accuracy of data operation with hardware cost, area and power consumption.
Abstract: LTE-A system, the UE and the eNodeB cell synchronization process is very important, it can detect the physical layer cell ID and access to time and frequency synchronization, and then process data communication. The key to cell synchronization is to acquire the cell ID. The ID of the cell can be obtained by ID blind detection, and the cell system information can be obtained. Therefore, it is very important to get the cell ID quickly and accurately. With the constant updating of the protocol, the design of the user's receiving end is also constantly updated. This paper proposes a reasonable and feasible ASIC design scheme and valid UVM (Universal Verification Methodology) verification platform from the perspective of studying the cell ID blind detection algorithm as well hardware implementation by balancing the fast accuracy of data operation with hardware cost, area and power consumption, it has important practical significance. Compared with the same module of other design, ASIC design of this area is 8.8% lower, 9.3% lower power consumption than the other design.

05 Oct 2020TL;DR: The authors present the concept of using the Cell Range Extension parameter in coordinated LTE-A networks to improve network throughput by proper user assignment to the BS.
Abstract: Deployment of small cells in heterogeneous network is directly related to the problem of right user association between macro- and small-cell base station. In order to force just selection of appropriate base station, additional component is added to the measured path loss (signal strength) in order to modify, i.e. virtually extend or squeeze, the cell radius. In this short paper, the authors present the concept of using the Cell Range Extension parameter in coordinated LTE-A networks. Within the coordination area that covers numerous base stations, the values of CRE are tuned in such a way that the achieved network throughout is improved. It is to improve network throughput by proper user assignment to the BS.

02 May 2018TL;DR: The numerical results presented show that the deployment of the femtocells improve the overall QoS considering the mobile users.
Abstract: Recently, femtocells are likely to be deployed at homes and small enterprises in an urban area to improve the coverage and capacity of the systems. Thus, in order to improve QoS in wireless and mobile networks overlay an existing macrocell network with indoor femtocell is an alternative solution for service operators. Mobility is also one of the main issues in performance evaluation of wireless systems. There is a lack of analysis that provides the deployment of femtocells in an existing macrocell network considering the mobile users. Hence, the impact of mobile users and the deployment of femtocells in a macrocell presented using an open source simulator. An open source simulator is adapted and different scenarios are considered for a typical urban area as case study where a set of femtocells are deployed within the coverage area of a macrocell. The numerical results presented show that the deployment of the femtocells improve the overall QoS considering the mobile users.

24 Sep 2012TL;DR: A low-overhead LTE-Advanced relay network handover scheme concentrates on reducing signaling cost while ensure users' QoS.
Abstract: This paper raises a low-overhead LTE-Advanced relay network handover scheme When relay involved in the LTE-Advanced cellular network, handover scenario and process will become more complicated We consider two-hop relay network, the backhaul hop (BS-RS hop) resource is very precious and become a bottleneck of LTE-Advanced network performance Directly using traditional handover scheme in relay network will bring in a lot of backhaul signaling So a new handover scheme is raised The scheme concentrates on reducing signaling cost while ensure users' QoS
