RedCap can be simply understood as a "lightweight, simple 5G". According to preliminary industry estimates, RedCap can reduce the complexity and cost of 5G terminals by 50% to 65% by reducing terminal bandwidth, the number of transceiver antennas, and the number of modulation orders. This has an obvious driving effect on the scale application of 5G terminals and the expansion of 5G application scenarios, and is particularly prominent in landing applications in the field of the Internet of Things. On March 23, the third Global 6G Technology Conference was held in Nanjing to deeply explore 6G network transformation and technological innovation. Just like the "handover" between 4G and 5G, the technological iteration in the communication field is not a "life to death" struggle, but a long-term complementarity and coexistence. 6G seems to be in sight, while 5G has not stopped the pace of technological evolution. Not long ago, China Telecom Group Co., Ltd., together with Huawei Technologies Co., Ltd. and other industrial partners, released the "China Telecom 5G RedCap Industry White Paper" (hereinafter referred to as the "White Paper"), which was prepared with the participation of 18 core module and network equipment manufacturers. From the perspective of industry progress, technical characteristics, terminal demand Industry applications and other aspects have drawn a panorama of the development of lightweight terminals (RedCap) from macro to practical implementation. Driven by the joint efforts of relevant industry organizations, telecommunications operators, equipment manufacturers, and chip companies, the 5G RedCap industry has achieved a spectacular landing momentum, pushing the 5G empowerment of thousands of industries deeper and wider. The important puzzle of 5G applications is known as the "Little Red Riding Hood" RedCap, which can be simply understood as "a lightweight, simplified version of 5G.". According to preliminary industry estimates, RedCap can reduce the complexity and cost of 5G terminals by 50% to 65% by reducing terminal bandwidth, the number of transceiver antennas, and the number of modulation orders. This has an obvious driving effect on the scale application of 5G terminals and the expansion of 5G application scenarios, and is particularly prominent in landing applications in the field of the Internet of Things. In June 2022, RedCap achieved a standard freeze in the 3GPP R17 phase. "As an enhanced standard for 5G, R17 is geared towards new business requirements such as 5G's expansion into reality and the new Internet of Things, with a focus on introducing multiple technical features, including RedCap." According to Li Yan, vice president of Qualcomm Technical Standards, R17 continues 5G's "commitment" to the entire industry, from connecting people to more applications in thousands of industries. RedCap is one of the most focused technologies. 5G, characterized by ultra-large bandwidth, ultra-large capacity, and ultra-low latency, has achieved significant industrial application results, but its capabilities cannot fully cover all wireless scenarios. At the same time, the pain points such as high module prices, high power consumption, and severe fragmentation of industry applications have become obstacles to the development of 5G. Wang Zhijun, Senior Vice President of Marketing and Sales of Beijing Zhilian An Technology Co., Ltd., said that as we all know, 5G defines three scenarios - Enhanced Mobile Broadband (eMBB) for large bandwidth applications, Ultra High Reliable Ultra Low Delay Communication (uRLLC) for high reliability ultra low delay applications, and Massive Machine Communication (mMTC)
