1 / 112 “METHOD AND APPARATUS USED IN A NODE FOR WIRELESS COMMUNICATION” FIELD OF TECHNOLOGY

[0001] This application relates to a method and apparatus for transmission in a wireless communication system, in particular, a method and apparatus for uplink synchronization in wireless communication. BACKGROUND OF THE INVENTION

[0002] In the future, the application scenarios for wireless communication systems will become increasingly diverse, and different application scenarios will advance different performance requirements for the systems. To meet the different performance requirements of various application scenarios, the 3GPP (3rd Generation Partnership Project) RAN (Radio Access Network) Plenary Session No. 72 decided to study a new radio (NR) (or 5G) technology, and a WI (Work Item) for new radio (NR) technology was approved at the 3GPP RAN Plenary Session No. 75, and work on standardization in NR was initiated.

[0003] In new radio technology, synchronous uplink transmission is one of the most basic requirements. In order to adapt to various application scenarios and meet different needs, 3GPP has been developing uplink synchronization technologies. SUMMARY OF THE INVENTION

[0004] When UE (user equipment) is moved from one cell's coverage scope to another cell's coverage scope, a UE server cell needs to be changed, i.e., it needs to be transferred from a source cell to a target cell. Changes to the server cell are usually triggered by L3 (Layer 3) metering and implemented through reconfiguration with synchronization driven by RRC (Radio Resource Control) signaling. Changes to service cells implemented at L3 exhibit characteristics such as long delay, high signaling overhead, and long downtime. To overcome these shortcomings, a 3GPP (3rd Generation Partnership Project) RAN (Radio Access Network) introduced dual connectivity (DC), conditional PSCell (conditional PSCell change). Petition 870250111517, dated 04 / 12 / 2025, page 6 / 123 2 / 112 (Primary SCG Cell (Secondary Cell Group), CPC), conditional addition of PSCell (CPA), conditional handover (CHO), and other technologies in Rel (release)-17, and all these technologies are implemented based on L3. At the 3GPP RAN #94e plenary meeting, it was decided to initiate work on standardizing the WI (Work Item) for a mobility enhancement technology based on L1 / L2 (Layer 1 / Layer 2). A design goal of the L1 / L2-based mobility enhancement technology is to implement fast transfer of EU service cells. In response to the demand for uplink synchronization for mobility enhancement in an NR system, this application discloses a solution.It should be clarified that, in the description of this application, mobility enhancement is used only as a typical application scenario or example; and the designs presented here are also applicable to other scenarios facing similar problems (such as other scenarios requiring multi-cellular uplink synchronization, including, but not limited to, multi-antenna systems, multi-TRP (transmitter-receiver point) systems, capacity augmentation systems, short-range communication systems, unlicensed frequency domain communication, IoT (Internet of Things), URLLC (Ultra-Reliable Low Latency Communication) networks, Internet of Vehicles, etc.), and similar technical effects can also be achieved. Furthermore, the use of a unified solution for different scenarios (including, but not limited to, multi-carrier scenarios) also helps to reduce hardware complexity and costs.If there is no conflict, the modes and features of the modes in a first-node device of this application may be applied to a second-node device and vice versa.
