Low-Rate Machine-Type Communication via Wireless Device-to-Device (D2D) Links

2014-10-30 上传
Wireless cellular networks feature two emerging technological trends. The first is the direct Device-to-Device (D2D) communications, which enables direct links between the wireless devices that reutilize the cellular spectrum and radio interface. The second is that of Machine-Type Communications (MTC), where the objective is to attach a large number of lowrate low-power devices, termed Machine-Type Devices (MTDs) to the cellular network. MTDs pose new challenges to the cellular network, one if which is that the low transmission power can lead to outage problems for the cell-edge devices. Another issue imminent to MTC is the massive access that can lead to overload of the radio interface. In this paper we explore the opportunity opened by D2D links for supporting MTDs, since it can be desirable to carry the MTC traffic not through direct links to a Base Station, but through a nearby relay. MTC is modeled as a fixed-rate traffic with an outage requirement. We propose two network-assisted D2D schemes that enable the cooperation between MTDs and standard cellular devices, thereby meeting the MTC outage requirements while maximizing the rate of the broadband services for the other devices. The proposed schemes apply the principles Opportunistic Interference Cancellation and the Cognitive Radio’s underlaying. We show through analysis and numerical results the gains of the proposed schemes

IMT-2030（6G）

2023-09-11 上传
IMT-2030指的是第三代移动通信技术（International Mobile Telecommunications-2030），也被称为6G。根据引用中提到的通信感知一体化技术研究报告，IMT-2030的研究工作主要包括了6G应用场景需求、基础理论、空口技术...

上层如何修改IMT2000为IMT2100

2023-05-30 上传
如果你想将已有的IMT-2000系统修改为IMT-2100系统，需要进行一系列的技术更新和改造。由于IMT-2000和IMT-2100采用的技术不同，因此需要进行以下方面的改造： 1. 改变系统的物理层技术：IMT-2000采用了WCDMA、...

imt定义的5g需求，峰值速率应达到

2023-06-25 上传
IMT-2020技术特性中规定，5G的峰值速率应该能够达到每秒20Gbps的速度。 这种高速率的需求来源于用户对高带宽和低延迟的需求，这种需求来自于新兴应用，如VR（虚拟现实）、AR（增强现实）、8K视频流媒体等等。在这些...

if tz~=3 disp ('img2 must be a color image (not indexed)'); else imt(:,:,2)=imt(:,:,1); imt(:,:,3)=imt(:,:,1);

2023-05-01 上传
这是一段 MATLAB 代码，意思是如果变量 tz 不等于 3，那么输出一个字符串 'img2 must be a color image (not indexed)'，否则将 imt 的第二维和第三维都赋值为 imt 的第一维。其中，imt 是一个三维的图像矩阵，表示...

Android ART 中imt表指什么

2023-07-08 上传
在Android ART (Android Runtime)中，imt 表是指 Interface Method Table（接口方法表）。它是一个虚拟函数表，用于存储接口的方法引用和实现。每个实现了接口的类都会有一个对应的 imt 表。 imt 表的作用是为了...
