In order to guarantee the high rate, high throughput and low latency and reliable service provided by TD-LTE system under various mobility conditions, handover (HO) procedure and its performance are of high importance. Based on research on structure of TD-LTE system and RRC (Radio Resource Control) layer, this paper proposed intra-system handover procedure in RRC layer of UE side. Simulation of the proposed design and implementation on SDL (Specification and Description Language) /TTCN (Tree and Tabular Combined Notation) verified its conforming to 3GPP conformance protocol specification. Finally, proposed design was verified on the chip ARM1176JZF-S with the corresponding software.

In the TD-LTE system, RRC (Radio Resource Control) layer plays a very important role as the control center in the whole higher layer protocol. This paper introduces the function of RRC layer and mainly focuses on the RRC layer connection reconfiguration. This paper also illustrates design of function, signaling process and uses the third party terminal and tracking software to calculate the corresponding diagram in the domain of log, which checks the implementation of RRC layer connection and reconfiguration.

Random Access Channel

In this paper, we have analyzed and developed different types of algorithms related to 5G accessibility procedures for Non Standalone (NSA) and Standalone (SA) mode. The 5G accessibility depends on 5G radio parameters of each procedure, such as contention based Random access (CBRA), contention free random access (CFRA), Radio admission control (RAC), Radio resource control (RRC) and Radio bearer reconfiguration. The random access procedure for NSA is similar to SA mode. The goal is to improve the accessibility by optimizing timers and tune the main 5G radio parameters related to Random access channel (RACH), RRC reconfiguration and RAC procedures.

The main goal of this article is to implement an effective Non-Blocking Benes switching Network. Benes Switching Network is designed with the uncomplicated switch modules & it’s have so many advantages, small latency, less traffic and it’s required number of switch modules. Clos and Benes networks are play a key role in the class of multistage interconnection network because of their extensibility and mortality. Benes network provides a low latency when compare with the other networks. 8x8 Benes non blocking switching network is designed and synthesized with the using of Xilinx tool 12.1.

Achieving the low-latency constraints of public safety applications during disaster could be life-saving. In the context of public safety scenarios, in this paper, we propose an efficient radio resource slicing algorithm that enables first responders to deliver their life-saving activities effectively. We used the tool of stochastic geometry to model the base station distribution before and after a disaster. In addition, under this umbrella, we also proposed an example of public safety scenario, ultrareliable low-latency file sharing, via in-band device-to-device (D2D) communication. The example scenario is implemented in NS-3. The simulation results show that radio resource slicing and prioritization of first responders resources can ensure ultrareliable low-latency communication (URLLC) in emergency scenarios.

In order to verify the protocol conformance of radio resource control (RRC) connection reestablishment in LTE system, a new testing method is designed by implementing testing and test control notation version 3(TTCN-3) abstract test suit. Furthermore, the test suit is operated on the TTworkbench developed by German Testing tech. It also generates graphical presentation format (GFT) to check the protocol conformance of RRC functions. The scheme has been successfully applied in the project development of TTCN extended test set instrument in LTE system.

The background that underlies this work is the envisioned real-time tele-immersive collaboration system for the future that supports delay-sensitive applications involving participants from remote places via their collaboration spaces (CSs). The end-to-end delay as high as 20 ms is required for good synchronization of such applications, for example collaborative dancing and remote conducting of choir. It is much lower than that facilitated by existing teleconference systems. A novel network architecture with delay guarantee, namely Distributed Multimedia Plays (DMP), has been proposed and designed to realize the vision. The maximum low latency is guaranteed because DMP network nodes can drop DMP packets of multimedia data from the CSs due to instantaneous traffic condition. Besides ultrafast processing time, modularity, and scalability must be taken into account in hardware design and implementation of the nodes for seamless incorporation of the modules. These lead us to employing field-programmable gate array (FPGA) due to its substantial computational power and flexibility. This paper presents an FPGA-based platform for the design and implementation of DMP network nodes. It provides a detailed introduction to the platform architecture and the simulation-implementation environment for the design. The modularity of the implemented node is shown by addressing three important modules for packet dropping, 3D warping, and image transform. Our compact implementation of the network node on Xilinx Virtex-6 ML605 mostly consumes very small amount of available resources. Moreover the elementary operations on our implementation takes (much) less than 5 μs as desired to meet the low-latency requirement.
