This paper proposes a Packet Data Convergence Protocol (PDCP) traffic filtering with virtual distributed unit (vDU) and central unit (vCU) hot-backup to reduce the fronthaul connection recovery time during the virtualized function failure. This architecture permits to maintain the communication between the Evolved Packet Core (EPC) and the User Equipment (UE). Experimental results show that a service recovery time is able to achieve in three seconds.

Spatial modulation uses index modulation (IM)-based transmission scheme to reduce transmitted power and radio-frequency (RF) chains in multiple antenna systems. In this paper, we propose IM and non-orthogonal multiple access (NOMA) based IM-NOMA system (I-NOMA) to support massive connectivity in a wireless network. In the proposed downlink I-NOMA, users are multiplexed using both the transmit antenna index and different power levels at base station. The symbol error rate (SER) and sum rate performances of the proposed I-NOMA are analyzed and compared with the IMbased orthogonal multiple access (OMA) system. Impact of various system parameters such as modulation order, transmit antennas, imperfect channel estimation are studied in I-NOMA. Results show that the proposed I-NOMA can yield better sum rate performances than the conventional IM-OMA with good SER and low complexity transceivers.

Over last 4-5 years, there has been tremendous development globally towards autonomous driving. However, in order to understand the neighborhood road environment, solutions using Camera, RADAR and LIDAR have significant disadvantages. The primary drawback being that the vehicles should be in visible/direct line-of-sight of each other. In this regard, vehicle-to-vehicle communication (V2V) has a great advantage that it enables transmission of information from one vehicle to another even if they are not in the line-of-sight range. The expected data rate in next generation connected vehicles for autonomous driving is expected to be in the range of 100 Mbps or higher. In this regard, a relay-based multi-hop V2V mechanism has been explored for communication between far-located source and destination vehicle. However, the number of multiple hops in V2V would affect the resource allocation in 5G/next generation network. This paper investigates the number of multiple hops required as the maximum transmission range is varied. Importantly, the paper investigates the complexity in the resource allocation as the number of multiple hops among source and destination vehicle is increased. The number of multiple hops required increases exponentially, when the communication range is around 0.3 times the maximum transmission range. Further, there is a humongous increase in the complexity of resource allocation when the number of multiple hops increase. Especially with spatial reuse in multi-hop mode, the complexity of resource allocation increases to 1080 for a 50-node vehicular network. This is an important aspect to be considered while designing next generation connected vehicle environment.

Cognitive Radio (CR) is expected to play an important role in 5G wireless communications to meet the challenging requirements of massive Machine-to-Machine (M2M) connectivity and Internet of Things (IoT). CR networks should be capable of wideband spectrum sensing (WSS) to provide opportunistic spectrum access and to abate spectrum scarcity. However, WSS approaches are severely limited by the analog to digital converter (ADC) speeds. Sub-Nyquist samplers alleviate the burden on ADC by compressively sampling a wideband signal. This paper focuses on two such samplers, Analog to Information Converter (AIC) and Modulated Wideband Converter (MWC), both of which exploit spectral sparsity. Specifically, a partitioned WSS scheme is proposed with modified AIC and MWC samplers. Real-time signal in the UHF TV band (470-790) MHz is acquired by a Software Defined Radio (SDR) and occupied/vacant bands are detected using the proposed WSS approach. Orthogonal Matching Pursuit (OMP) and Sparse Bayesian Learning (SBL) based sparse recovery approaches aided in this detection. Support recovery performance from both simulations and experimental investigations show that the proposed approach has a good potential for WSS in M2M and IoT applications.

Deep learning has been applied recently in the wireless communication area such as modulation classification, channel estimation and signal detection. Many of the wireless communication problems can be modeled as classification problems. Residual learning has proven to have a crucial role in image recognition for providing fascinating classification accuracy. This paper proposes a residual learning-based autoencoder model that can jointly optimize the transmitter and the receiver while communicating over Rayleigh flat fading and bursty noise channels. Depending on the number of bits per symbol at the transmitter, the proposed system can automatically learn the constellation mapping and reconstruct the transmitted bits with very low loss metrics. Simulation studies show that the block error rate performance of the proposed model is superior to the convolutional layer based autoencoder system as well as the conventional modulation system under Rayleigh flat fading and bursty noise channels.

we have become too dependent on technology owing to which the quantity of e-waste produced at the end of their life cycle has increased at a rapid pace. In later centuries, there would be an equivalent amount of carbon footprint by the smartphone sector as to that of transportation industry. The approximate estimation of the total carbon footprint while taking the other existing abundant electronic gadgets is enormous. Considering the growing volume of e-waste, the possibilities of these non-biodegradable elements contaminating the atmosphere are towering. The e-waste generated in all these recent years is being taken seriously by various nations and effective steps are being taken to overcome this challenge. To overcome this challenge, an effective e-waste management technique by means of blockchain in the 5G scenario is proposed. The proposed solution tracks the e-waste produced and motivates people by providing incentives to them for channelizing the e-waste via agencies managed by the government that effectively dispose the waste in an environmentfriendly way. Henceforth, a partnership model is proposed for the implementation of this method which leads to increase in jobs as well as proper organization of unplanned setup that is with a large amount of prospective potential.

Network functions virtualization (NFV) has matured as a technology to the point that it is now being embraced operationally by communications service providers (CSPs) around the world, and we see a paradigm shift, where there are many field trials and proof-of-concept on 5G is aggressively encompassing all the verticals, and security is becoming increasingly important to successful Software Defined Networking (SDN) and Network Functions Virtualization (NFV) deployments for 5G.

Multi SIM (Multi Subscriber Identity Module) Multi Standby (MSMS) feature-enabled User Equipments (UEs) hold a big share in the mobile market and expected to dominate the smartphone industry for the next decade too. Predominantly, MSMS UEs are designed with a single Radio Frequency Integrated Circuit (RFIC) to save cost and to serve the Protocol Stack Unit (PSU) of each SIM in a time-sliced manner. As a result, the amount of time RFIC is kept powered ON is higher in MSMS UEs than that in single SIM UEs and it increases with an increase in SIM count in MSMS UEs. This increased RFIC usage leads to more power consumption inherently causing a much faster battery drain compared to single SIM UEs. Connected mode Discontinuous Reception (CDRX) is a power-saving technique in 5G where networks attempt to bring a balance between Quality of Service (QoS) and power consumption. Based on the traffic pattern, 5G networks predict the RFIC usage pattern and compute the CDRX configuration for the single SIM UEs. For MSMS UEs, the network connected to SIM-1 cannot determine the optimal DRX configuration as it cannot predict the RFIC usage of all the SIMs based on the SIM-1 traffic pattern. To address the above-said problem, we propose a novel mechanism called UCM (UE defined C-DRX for MSMS UEs) in this paper. UEs shall optimally compute C-DRX configuration based on overall RFIC ON duration considering the events of other SIMs too and share it with 5G networks. Key Performance Indicators (sleep ratio and mean packet buffering delay) of the new CDRX mechanism are qualitatively compared with the legacy. Results reveal that UCM achieves better power saving with little increase in packet latency.
支持多SIM(多用户身份模块)多待机(MSMS)功能的用户设备(ue)在移动市场占有很大份额，预计在未来十年也将主导智能手机行业。MSMS ue主要采用单个射频集成电路(RFIC)设计，以节省成本并以分时方式为每个SIM卡的协议堆栈单元(PSU)提供服务。因此，在MSMS ue中RFIC保持开机的时间比在单个SIM ue中要长，并且随着MSMS ue中SIM数量的增加而增加。这种增加的RFIC使用会导致更多的功耗，从而导致与单SIM ue相比更快的电池消耗。连接模式不连续接收(CDRX)是5G中的一种节能技术，网络试图在服务质量(QoS)和功耗之间取得平衡。5G网络根据流量模式预测RFIC使用模式，并计算单SIM终端的CDRX配置。对于MSMS ue，连接到SIM-1的网络无法确定最佳DRX配置，因为它无法根据SIM-1流量模式预测所有sim的RFIC使用情况。为了解决上述问题，本文提出了一种名为UCM (UE defined C-DRX for MSMS UE)的新机制。ue应考虑到其他sim卡的事件，根据整体RFIC on持续时间优化计算C-DRX配置，并与5G网络共享。对新CDRX机制的关键性能指标(睡眠率和平均数据包缓冲延迟)与旧机制进行了定性比较。结果表明，UCM在不增加数据包延迟的情况下实现了更好的节能。

In May 2018 the General Data Protection Regulation (GDPR) entered into force in all Member States of European Union (EU) and its principles received a worldwide interest and acceptance. It represents a fundamental normative step forward for the protection of personal data in the future Internet systems. However, 5G networks, Artificial Intelligence technologies and the Internet of Things raise security and privacy issues that could not be addressed only by GDPR, even assuming its complete compliance by the service providers. In addition and in synergy with GDPR rules, we need innovative scientific and technical solutions to guarantee the complete control to the users to the access and the use of their personal data.

It represents a fundamental normative step forward for the protection of personal data in the future Internet systems.

In addition and in synergy with GDPR rules, we need innovative scientific and technical solutions to guarantee the complete control to the users to the access and the use of their personal data.
