Efficient detection methods for amplify-and-forward relay-aided device-to-device systems with full-rate space-time block code

引用

Frontiers of Information Technology & Electronic Engineering 2017年第6期18卷 788-795页

作者： Kang-li ZHANG Cong ZHANG Fang-lin GU Jian WANG College of Electronic Science and Engineering National University of Defence Technology School of Electronic Information and Electrical Engineering Shanghai Jiao Tong University

Relay-aided device-to-device (D2D) communication is a promising technology for the next-generation cellular network. We study the transmission schemes for an amplify-and-forward relay-aided D2D system which has multiple antennas. To circumvent the prohibitive complexity problem of traditional maximum likelihood (ML) detection for full-rate space-time block code (FSTBC) transmission, two low-complexity detection methods are proposed, i.e., the detection methods with the ML-combining (MLC) algorithm and the joint conditional ML (JCML)detector. Particularly, the method with the JCML detector reduces detection delay at the cost of more storage and performs well with parallel implementation. Simulation results indicate that the proposed detection methods achieve a symbol error probability similar to that of the traditional ML detector for FSTBC transmission but with less complexity, and the performance of FSTBC transmission is significantly better than that of spatial multiplexing transmission. Diversity analysis for the proposed detection methods is also demonstrated by simulations.

Optimal transmission mode proportion for heterogeneous networks of cellular and device-to-device communications

引用

The Journal of China Universities of Posts and Telecommunications 2013年第4期20卷 21-27页

作者： LIU Zi-yang PENG Tao WANG Wen-bo Key Laboratory of Universal Wireless Communications Beijing University of Posts and Telecommunications

This paper discusses about the optimal mode allocation for the heterogeneous networks, in which the network can schedule users working in the device-to-device （D2D） mode or cellular mode. The D2D user is allowed to reuse the uplink resource of cellular system and the problem is formed as a sum-capacity optimization issue with outage constraints for both cellular and D2D links. The method for the optimal user proration is proved to be divided into three cases according to the total user density： when the total user density is small, the optimal proration trends to all users utilizing one mode; when the total user density is large, the optimal proration is all of users choosing D2D mode; and when the total user density situates in the between, there is a unique optimal transmission mode proportion for the hybrid networks to maximize its sumcapacity. The simulation results demonstrate the validity of the conclusions in the analysis part.

Coverage Probability Analysis for Full-Duplex Relay Aided device-to-device Communications Networks

引用

China Communications 2016年第11期13卷 60-67页

作者： Bin Zhong Jiajia Zhang Qian Zeng Xiaoming Dai School of Information and Electrical Engineering Hunan University of Science and Technology Beijing Engineering and Technology Research Center for Convergence Networks and Ubiquitous Services University of Science and Technology Beijing Business School Xiangtan University

The coverage probability of both the cellular users and the device-to-device(D2D) users are analyzed. We assume that the cellular users are able to communication with the Base Station(BS) either by relying on the assistance of Full-Duplex(FD) mode relays or via direct user-to-BS links with high-enough Signal-to-Interference-plus-Noise-Ratio(SINR). Note that the FD-mode devices are capable of simultaneously operating in two modes,i.e. the D2D mode and the cooperative relay mode,with the sum power consumption at these devices kept constant. The closedform expressions for coverage probability of both tier users are derived. After that,numerical analyses are provided,showing that the coverage probability of the both the cellular and the D2D users can be substantially influenced by a variety of parameters,including the power allocation factor of the relays,the density of users,and the self-interference imposed on the FD mode relays,etc. Furthermore,in the D2D enabled networks,it is shown that the FD relay aided transmission is beneficial to enhancing the coverage probability of the cellular users if the target SINR is lower than 5 d B.

Resource Allocation Method of device-to-device Communication

引用

Communications and Network 2013年第3期5卷 338-343页

作者： Wenji Feng Yafeng Wang Lei Yang Wireless Theory & Technology lab (WT&T) Beijing University of Posts and Telecommunications Beijing China

In this paper, we study D2D (device-to-device) communication underlying LTE-Advanced uplink system. Since D2D communication reuses uplink resources with cellular communication in this scenario, it’s hard to avoid the inference between D2D users and cellular users. If there is no restriction for D2D communication on using the whole uplink frequency band, it will have a strong negative impact on cellular communication. In order to overcome this shortage, we propose a resource allocation method that D2D users and cellular users use orthogonal frequency resources. This method will effectively reduce the inference between both kinds of communication. However, an obvious disadvantage of this method is no effective use of uplink resources. Based on this, we propose an optimized resource allocation method that a specific cellular user will be chosen to reuse the RBs (Resource Block) of D2D users. These ideas will be taken into system-level simulation, and from the results of simulation we can see that the optimized method has the ability to improve overall system performance and limit inference for cell-edge users.

device-to-device Communication Underlaying Cellular Communications Systems

引用

International Journal of Communications, Network and System Sciences 2009年第3期2卷 169-178页

作者： Pekka JANIS Chia-Hao YU Klaus DOPPLER Cassio RIBEIRO Carl WIJTING Klaus HUGL Olav TIRKKONEN Visa KOIVUNEN Department of Communications and Networking Helsinki University of Technology Espoo Finland Department of Signal Processing and Acoustics Helsinki University of Technology Espoo Finland Nokia Research Center Nokia Group Helsinki Finland

In this article we propose to facilitate local peer-to-peer communication by a device-to-device (D2D) radio that operates as an underlay network to an IMT-Advanced cellular network. It is expected that local services may utilize mobile peer-to-peer communication instead of central server based communication for rich mul-timedia services. The main challenge of the underlay radio in a multi-cell environment is to limit the inter-ference to the cellular network while achieving a reasonable link budget for the D2D radio. We propose a novel power control mechanism for D2D connections that share cellular uplink resources. The mechanism limits the maximum D2D transmit power utilizing cellular power control information of the devices in D2D communication. Thereby it enables underlaying D2D communication even in interference-limited networks with full load and without degrading the performance of the cellular network. Secondly, we study a single cell scenario consisting of a device communicating with the base station and two devices that communicate with each other. The results demonstrate that the D2D radio, sharing the same resources as the cellular net-work, can provide higher capacity (sum rate) compared to pure cellular communication where all the data is transmitted through the base station.

5G is a new generation of mobile networking that aims to achieve unparalleled speed and performance. To accomplish this, three technologies, device-to-device communication (D2D), multi-access edge computing (MEC) and network function virtualization (NFV) with ClickOS, have been a significant part of 5G, and this paper mainly discusses them. D2D enables direct communication between devices without the relay of base station. In 5G, a two-tier cellular network composed of traditional cellular network system and D2D is an efficient method for realizing high-speed communication. MEC unloads work from end devices and clouds platforms to widespread nodes, and connects the nodes together with outside devices and third-party providers, in order to diminish the overloading effect on any device caused by enormous applications and improve users’ quality of experience (QoE). There is also a NFV method in order to fulfill the 5G requirements. In this part, an optimized virtual machine for middle-boxes named ClickOS is introduced, and it is evaluated in several aspects. Some middle boxes are being implemented in the ClickOS and proved to have outstanding performances.
