A potential 6G technology called Reconfigurable Intelligent Surface (RIS) uses meta-surface to reflect the signal to the user. The usage of RIS as a passive full-duplex relay to support wireless communication is a strong one because of its distinctive qualities of low cost, low energy consumption, excellent reliability, and big capacity. At the same time, the related technology active full-duplex relay which evolves from traditional half-duplex relay is also a candidate 6G technology. Both RIS and full/half-duplex relay is a node between source and destination to improve the performance of system, so how to choose between them? In this study, we examine the two technologies' performance from the viewpoint of the operators. In order to make the comparison fair, an evaluated model is proposed, and we get the closed expression of achieved rates for RIS and active relay to provide a deterministic calculation for the comparison. The results show that both RIS and full-duplex active relay are effective for the performance improvement, which of the two has the higher achieved rates is determined by the element number of RIS and the self-interference suppression of full-duplex relay.

In this paper, a new radar-assisted beam prediction method is proposed based on SqueezeNet model for millimeter wave system. We use a large real data set to test our proposed radar aided optimal beam prediction model, DeepSense6G, which includes millimeter-wave beam training and radar measurement. In the test results section of this paper, we can see that our model has achieved a good balance between prediction accuracy and model complexity. In addition, the prediction accuracy of the first five beams of the proposed model can reach about 94%, and at the same time, it saves a lot of beam training overhead.

With the continuous development of media convergence, in order to solve the problem that traditional technical architecture and business architecture are not suitable for new services, this paper proposes a media microservice architecture (MMA) and cloud-native microservice key technologies, and plans seven business domains suitable for audiovisual media.

Small cells are being deployed in the most recent Heterogeneous Network (HetNet) environments, which are supported by 5th-generation (5G) network solutions. They improve the performance of conventional macro-cell networks. Before data transmission in HetNets begins, a process of user association (UA) with a particular base station (BS) is triggered. Diverse resource allocation (RA) algorithms are also used during data transmission. Enhancing network load balancing, spectrum performance, and energy efficiency are all important goals that UA-RA solutions help to achieve. The authors of this paper previously presented a meta-heuristics algorithm for solving UA-RA problems in HetNets known as Performance-Improved Reduced Search Space Simulated Annealing (PIRS3A). Still, PIRS3A is only suitable for scenarios with low number of users as its complexity increases with the increase in the number of users. In this paper, we enhance the PIRS3A to support a large number of users by using Machine Learning (ML). We propose the Enhanced PIRS3A (EPIRS3A) which uses supervised ML techniques to classify users into two separate classes, i.e., users who need offloading and users who do not. PIRS3A will be used to solve the UA-RA problem for those users who need offloading in order to improve the quality of their services.

LTE-based 5G terrestrial broadcast, which is standardized in 3GPP Rel-14 and Rel-16, is one of the two technical evolutional-routes of 5G broadcast. In physical layer, the mobile reception performance loss of LTE-based 5G terrestrial broadcast majorly stems from numerology, coded modulation, interleave depth and channel estimation. Among these factors, interleave depth directly affects the mobile reception performance at different speeds, and low-speed mobile reception puts forward higher requirements of interleave depth. In this paper, the typical configuration of LTE-based 5G terrestrial broadcast is selected, and how interleave depth influences the mobile reception performance is revealed based on the analysis of average mutual information (AMI) probability density distribution and outage probability over small-scale Rayleigh fading channels. The analysis results show that the mobile reception performance could be significantly improved by appropriately increasing the interleave depth. Hence increasing interleave depth could be considered for the evolution of LTE-based 5G terrestrial broadcast towards the next generation mobile broadcast systems.

Recently, enhanced video compression frameworks compatible with traditional standard codecs have achieved competitive performance especially in low-bandwidth scenarios, among which the downsampling-based preprocessing networks and super-resolution based postprocessing networks are commonly applied. Surrogate networks are further employed as the replacement of non-differentiable standard codecs during training. However, the discard of minor information such as high frequency spatial textures in the process of downsampling restricts the reconstruction quality. Moreover, existing surrogate networks merely imitate the intra-frame coding structure of standard codecs without leveraging inter-frame relations. In this paper, we propose a rescaling-based enhanced video compression framework. The main video stream preserves critical spatial structures and complete temporal information, while another lightweight segment-specific enhancement stream transmitted to the decoder side is extracted and encoded from the key frame of a video segment. The high-frequency spatial information contained in the enhancement stream is further transferred to the whole segment with the guide of decoded LR frames via a Transformer-based Reconstruction Network (TRN), thus enhancing the reconstruction quality at the expense of a small bit cost. Besides, we employ a Virtual Codec Network (VCN) during training for gradients back-propagation, which is able to imitate both inter-frame and intra-frame coding characteristics of standard codecs. Experimental results indicate the superiority of the proposed approach compared with recent downsampling-based enhanced standard compatible frameworks.

This paper introduces a model modification procedure to adapt single-frequency network (SFN) channel models to the receiver directivity. The presented work is a sequel of [1], extending the modeling framework in a parametrically adjustable form. Behind this extension, it is remarked that channel fading in SFNs can be realized differently if the receiver changes antenna beam pattern or orientation. To reflect this aspect, the proposed method recalculates the channel response gain of each signal incidence as dependent on the network’s geometric layout and antenna directivity figure. By virtue of this reconfiguration ability, measurement-driven SFN channel models acquire an extra capability of more realistic simulations on various transmission scenarios. The existing channel characterization and modeling results would accordingly become more versatile, possibly beyond digital television use cases. For explicit demonstration, we present a modification example of S3-Extended model.

Wireless backhaul and inter-tower communications networks (ITCN) were previously proposed as crucial enabling technologies for the next generation of digital broadcasting systems, e.g., the Advanced Television Systems Committee (ATSC) 3.0 system. It is desirable to consider using multi-input multi-output (MIMO) for service delivery in ITCN to achieve better bandwidth efficiency. In ITCN, the transmitter can obtain channel states information (CSI), which could be applied in MIMO precoding. For the first time, this paper introduces the symbol-level precoding (SLP) scheme, which uses CSI and data symbols to precode to ATSC 3.0. Meanwhile, an enhanced SLP method for condensed non-uniform constellation (NUC) in modulation and coding schemes (MCSs) with a low code rate (CR) is proposed. Simulation results of the 64-NUC show that the proposed scheme performs better than Minimum Mean Square Error (MMSE), Zero-forcing (ZF), and ATSC 3.0 MIMO precoding.

The evaluation of free-viewpoint video (FVV) quality is essential for improving the quality of experience (QoE). Prior deep video quality assessment (VQA) approaches for FVV typically focused on either spatial or temporal distortions and lacked a comprehensive assessment considering the two aspects. In this paper, we provide an end-to-end no-reference video quality assessment (NRVQA) model for FVV that predicts video quality scores based on both spatial and temporal features. It consists of a spatial feature perception module, a temporal motion feature perception module and a quality score fusion module. In order to provide a quality score that is highly relevant to the mean opinion score (MOS) from the subjective quality assessment experiment, the quality-related features in the spatial and temporal domains of FVV are effectively utilized and merged. Experimental results show that the PLCC and SRCC improved by 25.0% and 18.5%, respectively, compared to state-of-the-art method. Moreover, the ablation experiments demonstrate the importance of both spatial features and temporal motion features.
