This report presents a mobile hotspot network system to provide mobile Internet services for the passengers in the high speed trains. 3GPP has been working on enhanced mobile broadband under many deployment scenarios such as indoor hotspots, dense urban, rural, high speed, etc. The high speed deployment scenario deals with continuous coverage along track in the high speed trains considering mobility of up to 500 km/h. The design concept of the mobile hotspot network system is in line with the 3GPP deployment scenario. The system will eventually provide the fifth generation mobile network services based on the very wide bandwidth of millimeter waves. The designs and architecture of the system will be disclosed. Also, the performance and mobility management issue will be addressed. A proof-of-concept demonstration with the system prototype will be presented.

One of the challenges facing the deployment of massive machine type communications in mobile networks is the overload in the radio access. When high number of devices attempt to access the system in a random access procedure, a collision happens and the transmitted data will be lost. As the base-station is not aware of how many users are colliding, it will not be able to resolve the collision. In this paper, we propose a method that enables the base-station to detect the number of colliding users in random access schemes. The proposed method capitalizes on the unique feature of frequency quadrature amplitude modulation (FQAM) that the number of active subcarriers in a FQAM symbol depends on the number of users transmitting on that symbol. Thus, in the proposed method, FQAM will be used by the users for the random access, and the base-station will estimate the number of colliding users based on the number of active subcarriers. We provide in details the channel structure, procedures and theoretical derivation of the average number of active subcarriers. Numerical simulations show that by using the proposed method the number of colliding users can be accurately detected at the base-station. Furthermore, it is shown that, with the knowledge of the number of colliding users, the base-station can successfully retrieve the users' data, and the performance of the random access schemes can be significantly enhanced.

We present NetCheck, a network policy language for verifying large-scale networked infrastructures. NetCheck is expressive enough to capture basic network properties such as reachability and maintenance, as well as more complex behaviours such as end-to-end connectivity, traffic isolation or tunnel invariance. NetCheck is fully-automated, and does not require any intervention on the network under scrutiny. It is deployed on an automatically-generated model of the network data plane, expressed in the SEFL language. NetCheck relies on symbolic execution for exploring all feasible paths through the network.

The D2D communication has high potential to serve multiple users with high data rate within a proximity in the next generation cellular networks. In this paper, we consider a multicast scenario of D2D users where each user wishes to receive the same multicast data at varying data rates. Based on our best knowledge, finding an optimal solution to satisfy the user request in the said context requires unreasonable time. Therefore, we have proposed approximation algorithms with two objectives (i) maximize the satisfied throughput, (ii) maximize the number of satisfied users when the available resource blocks are limited. The simulation results show that the proposed algorithms offer a worst-case performance guarantee and outperform the other conventional schemes in terms of throughput, satisfied users count, and fairness.

User Equipment (UE) paging and location tracking are influenced by the underling state handling model. There are recent proposals to introduce a new RRC state called RRC Inactive as a main state for inactive UEs in 5th Generation (5G) cellular systems. One of the characteristics of the new state is that the interface between the Radio Access Network (RAN) and Core Network (CN) is kept. Considering this characteristic, there are proposals for a RAN controlled paging and location tracking schemes for RRC Inactive UEs. In this paper, we show that this approach is not always beneficial, especially for high mobility UEs. Instead, we propose a hybrid paging and location tracking scheme where both RAN and CN are involved in the paging and location tracking of RRC Inactive UEs. This is done transparently to the UE. We further propose a hierarchical paging and location tracking scheme to reduce the signaling overhead from paging and location tracking updates. The scheme is applicable to both RAN based and CN based paging and location tracking schemes.

Mixed reality services promise to enhance our lives by providing us with real-time immersive media and contextual information delivered through lightweight wireless head mounted displays. We introduce a perception based mixed reality video streaming platform that reduces the data rate requirements for such services from several Gbps to 100 Mbps over a network that supports a 10 ms Round-Trip-Time. We expect mixed reality services first to be delivered through indoor and campus area networks and later through ubiquitous 5G networks. Our simulation and measurement results show that massive MIMO and millimeter wave transmissions can provide the required aggregate multi-Gigabit indoor data rates to support mixed reality services.

The journey towards the deployment of next generation networks has recently accelerated, driven by the joint effort of research and standards organisations. Some key innovative design concepts have been recently consolidating and are going to characterise the notable discontinuity between 4G and 5G systems. Among those, Architecture Modularisation, discussed in this paper, is regarded by the authors as the essential design principle to build a flexible network architecture natively supporting Network Slicing. According to this concept, conventional monolithic network functions, often corresponding to physical network elements in the existing systems, are to be split into basic building blocks defined with the proper granularity, allowing the definition of different logical architectures, tailored to 5G use cases. In this paper, a modularisation methodology is presented as a criterion to define the ‘right’ set of basic building blocks. Defined through this proposed methodology, the set of basic building blocks and the relating interfacing models are discussed. The paper concludes by proposing a candidate modular 5G network architecture, and comparing it with alternatives currently discussed within 3GPP standard working groups.

This paper proposes a model for radio resource management in virtualised radio access networks, based on the criterion of proportional fairness, which is also adapted to deal with the situations when there is not enough capacity to serve all subscribers with an acceptable level of service, the so-called the extreme case. A single virtual network operator providing four different classes of services negotiates the required capacity to serve its subscribers, from a centralised entity called Virtual Radio Resource Management (VRRM). The main goals of VRRM are to maximise the utilisation of resources, while maintaining a level of fairness in the allocation of data rate among different services. However, under extreme situations, the algorithm is modified to react differently, according to the offered traffic load. In general, it keeps serving a number of users having the stringiest Quality of Service (QoS), with the minimum guaranteed data rate, while the rest of users performing lowest QoS priority services are increasingly delayed. The performance of the proposed algorithm is evaluated through a practical heterogeneous network scenario and different evaluation metrics. Results show that when there is enough capacity, the algorithm is capable of satisfying the predefined service level agreements, while keeping fairness, whereas under extreme situations, it delays just enough number of users to free capacity for high priority services. In both cases, the algorithm is capable of maximising the utilisation of resources.

Centralized Radio Access Network (C-RAN) architecture is the enabling technology for the deployment of massive number of antennas essential to meet the requirements of next generation (5G and beyond) mobile systems. In C-RAN the fronthaul links between processing Base Band Units (BBUs) and Remote Antenna Units (RAUs) are conventionally based on fiber optic, although its deployment cost can be excessive. Radio over Copper (RoC) is an alternative/complementary technology for the fronthauling especially suitable for self-powered indoor deployment since it leverages on the pre-existing LAN cables. In this paper we consider a RoC C-RAN architecture as a low-cost bandwidth-efficient in-building solution to guarantee enhanced indoor coverage as required by 5G and beyond mobile systems. In particular, the focus of the paper is to gain insights into the optimal resource allocation to/from the RAU equipped with multiple antennas or multiple radios (e.g., 5G and WiFi) and the cable resources to fully exploit the capabilities of the twisted-pair cable over the last 50–100m. Numerical results validate the proposed method considering a realistic radio environment where the performance of indoor users are impaired by the interference of outdoor non-cooperating cells.

5G-Crosshaul aims at reducing network costs by designing an integrated transport (fronthaul/backhaul) network able to fulfill 5G requirements. Such transport networks will consist of heterogeneous technologies that need end-to-end orchestration. In this paper, we evaluate a hierarchical resource management framework for multi-domain wireless/optical networks. More specifically, we deploy a hierarchical 5G-Crosshaul Control Infrastructure (XCI) where child controllers deal with the specificities of each technology whilst the parent controller is in charge of offering to a resource management application (RMA) the appropriate abstraction level and an end-to-end view. To understand the end-to-end behavior related with service setup, we evaluate each network segment (wireless and optical), each plane (application and control planes), and each layer of the hierarchy inside the XCI. In particular, we evaluate the aggregated path setup time (in the order of seconds) as well as each component (wireless domain contributes with tens of ms and multi-layer optical network with hundreds of ms per layer for a total in the order of seconds). Path restoration results reveal the importance of leveraging control of child controllers when requiring fast response to unexpected data plane events, since an important part of the setup delay observed is due to the RMA-parent-child controller interaction and sequential message handling.
