Enhancing Mobility Standards The 3GPP is advancing cellular standards in Release 19 through the NR Mobility Enhancements Phase 4 (NR_Mob_Ph4) work item. This initiative aims to address limitations from Rel-18 by expanding LTM capabilities, supporting inter-CU operations, and improving L1 measurement handling. These enhancements promise smoother mobility and better measurement efficiency in NR systems. Tracking the Developments: Agenda Item 9.9.1 Agenda item 9.9.1, Measurements Related Enhancements for LTM, has seen significant contributions at RAN1#118 and RAN1#118-bis, paving the way for the upcoming RAN1#119 meeting. Key Contributions Contributors: Over 25 sources submitted 25 TDocs with 270 proposals at each meeting. Trends...

Background After RAN#105, the work item on Artificial Intelligence (AI)/Machine Learning (ML) for NR Air Interface (NR_AIML_air; refer to RP-242399 for details) was revised to target enhancing 5G network performance. This evolution builds on prior studies to specify the signaling and protocols needed for AI/ML applications like beam management, positioning, and CSI feedback, ensuring a seamless operation between the network and user equipment (UE). In the previous RAN2#127 meeting, delegates made several key agreements under agenda item 8.1.2.2 - LCM (Life Cycle Management) for the UE-sided model for Beam Management. These included: Definitions: Supported functionalities are those reported by the...

Background During the setting of cellular standards in Release 19, the work item NR Mobility Enhancements Phase 4 (NR_Mob_Ph4; refer to RP-241515 for the detailed scope of the WI) aims to address limitations introduced in Rel-18 by expanding LTM capabilities, supporting inter-CU operations, and enhancing L1 measurement capabilities. These enhancements ensure smoother mobility and efficient measurement handling in NR systems. In agenda item 9.9.1 - Measurements Related Enhancements for LTM (Layer 1/Layer 2 Triggered Mobility) at the previous RAN1#118 meeting, several important agreements were reached in R1-2407445, including: Support for L1-RSRP measurement based on CSI-RS, providing a more robust framework...

Introduction As the digital landscape evolves, the importance of setting robust and sustainable standards for Ambient IoT (A-IoT) within NR cannot be overstated. The FS_Ambient_IoT_Solutions work item is at the forefront of this endeavor, aiming to develop a new 3GPP IoT technology that is ultra-low in complexity and power consumption, yet capable of supporting the vast scale of future IoT applications. The Road to Standards At the upcoming RAN2#127 meeting, agenda item 8.2.3—A-IoT Paging—will be a central focus. Across 34 distinct TDocs, contributed by 32 different sources, 233 proposals aim to define how IoT devices will operate in real-world environments....

The future car is the hottest topic in the automotive market in recent years, which can be roughly divided into four technical fields: Connected Car, Autonomous Car, Sharing Car, and Electric Car, in sum, CASE[1] technology.  To understand the world's future car development, we cannot ignore China, which has the largest automobile production. Figure 1. Investment relationship of the Chinese automotive industry As shown in the investment relationship of the Chinese automotive industry in Figure 1, it includes investments, joint ventures, and cooperation between China's large traditional automakers (yellow blocks), large technology companies (purple blocks), and China's new automakers (green...

As a critical component of electric vehicles, batteries not only affect the endurance and performance of electric vehicles: they are also a key aspect of electric vehicles’ possible popularity in the future. With the rise of the electric vehicle industry, the global power battery field is also gradually moving towards a more mature stage where a hundred schools of thought compete in a rather fierce manner. Both Contemporary Amperex Technology Co. Limited (CATL) and China Aviation Lithium Electricity Technology Co., Ltd. (formerly known as China Aviation Lithium Battery Co., Ltd., or CALB) are China-based power battery manufacturers. Their batteries are...

As the joint pilot project between the European Patent Office (EPO) and the China National Intellectual Property Administration (CNIPA) is due to commence on December 1st, 2020, we took a look at the various benefits and drawbacks that this program may bring to the table.   Patent applications originating in China accounted for 5% of European applications in 2018. The number of Patent Cooperation Treaty (PCT) applications originating in China was seen to grow further in the following years.   The agreement is a development in a strategic partnership between the EPO and CNIPA that began in 2017. The EPO-CNIPA...

On August 6, 2020, United States President, Donald Trump, signed two executive orders prohibiting individuals and entities within the US from conducting any transactions with Chinese companies, ByteDance (the parent company of TikTok) and Tencent (the parent company of WeChat), which were due to be implemented on September 20, 2020.   In a statement issued by the US Department of Commerce, it claims: “While the threats posed by WeChat and TikTok are not identical, they are similar. Each collects vast data from users, including network activity, location data, and browsing and search histories. Each is an active participant in China’s...
