Abstract：COVID-19 infection spread rapidly throughout the country in early 2020 which caused medical resources scarce for a time. 5G smart medical can quickly alleviate the insufficiency through 5G network and other information technologies. This paper firstly analyzes the new demand of the epidemic situation for intelligent medical treatment，then introduces the innovative 5G bedside consultation scheme. Finally the effectiveness of the scheme is demonstrated through the practical application.

Abstract：Compared to the commercial 4G network, 5G needs to support larger RF bandwidths and more Tx/Rx channels to cater for the target requirement proposed by ITU, however, which results in significantly increased energy consumption for 5G base station. Base station energy-saving technology realizes the effective reduction of base station energy consumption by turning off the corresponding transmission resources in the time and frequency domains. In order to avoid the impact of energy-saving technology on network coverage and user experience, it is necessary to look for the balance between energy-saving effects and network performance during network operation. This article firstly analyzes the energy consumption model of 5G base stations, and evaluates the effect of power saving of 5G energy-saving technologies in combination with key factors affecting energy consumption. It analyzes the impact of related energy-saving technologies on network performance at the same time, and finally introduces the technology development trends and challenges of 5G power saving from the perspective of network operations.

Abstract：The ITU(International Telecommunication Union) defines three major 5G application scenarios: eMBB, mMTC and URLLC. With the maturity and commercialization of 5G, URLLC as an important entry point in the vertical industry is also gradually improving and optimizing. This paper firstly introduces the evolution of URLLC standard, and then analyzes the key technologies to achieve URLLC from three aspects of low latency, high reliability and multiplexing of URLLC and eMBB. Finally, the integration of URLLC and TSN is described.

Abstract：Recent years, the development of Time Sensitive Network(TSN) technology has gradually attracted widespread attention from industry. Characterized by low jitter, low delay and deterministic transmission, TSN has provided strong support for scenarios with high requirements of transmission delay. It has become one of the important evolution directions of the next-generation industrial network bearer technology. In order to meet the low-latency and high-reliability requirements of vertical industry services at the end-to-end level, 5G network has enhanced QoS, air interface synchronization, header compression and other aspects to meet the strict requirements of TSN network for 5G equipment on the basis of R15 URLLC. Starting from the demands of vertical industries, this article analyzes the necessity of the integration of TSN and 5G network. The needs and challenges of TSN for 5G commercial network transformation has also been studied based on the 3GPP R16 standardization progress in the end.

Abstract：By enhancing and expanding R15, 3GPP R16 standard makes 5G technical solution system and industry enabling ability more complete and more perfect, becoming an important milestone in 5G commercial process. In this paper, based on the current 5G challenges faced in the commercial development, around the "completed solution", "improved ability" and "industry expanding" three aspects, the requirements and characteristics of 5G R16 are analysed，and R17 follow-up technology evolution direction is forecasted.
