Description

1 / 106 “METHOD AND APPARATUS USED IN A NODE FOR WIRELESS COMMUNICATION” Technical Field

[0001] This application relates to a method of transmission and to an apparatus in a wireless communication system and, in particular, to a method and to an apparatus for uplink synchronization in wireless communication. Background of the Technique

[0002] The application scenarios for future wireless communication systems are becoming increasingly diverse, and different application scenarios impose different performance requirements on the systems. To meet the different performance requirements of various application scenarios, it was decided at the 72nd Radio Access Network (RAN) meeting of the 3rd Generation Partnership Project (3GPP) that research would be conducted on a New Radio (NR) technology (also called 5G). At the 75th 3GPP RAN meeting, an NR Work Item (WI) was approved and work on NR standardization was initiated.

[0003] In new radio technology, uplink synchronization transmission is one of the most fundamental requirements. To adapt to diverse application scenarios and meet different requirements, 3GPP has been continuously developing uplink synchronization technology. Summary of the Invention

[0004] When the UE (User Equipment) moves from one cell coverage range to another cell coverage range, it is necessary to change the UE's server cell, i.e., to handover it from a source cell to a destination cell. In the related technique, the server cell change is typically triggered by L3 (Layer 3) measurements and is implemented by reconfiguration with synchronization triggered by RRC (Radio Resource Control) signaling. The server cell change implemented at L3 has the characteristics of long delay, high signaling overhead, and long interruption time. To overcome the above shortcomings, the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) introduced technologies in Rel (Version)-17 such as DC (Dual Connectivity), CPC (Cell Changeover). Petition 870250102590, dated 10 / 11 / 2025, page 6 / 116 2 / 106 of Conditional PSCell (Primary SCG (Secondary Cell Group)), CPA (Conditional PSCell Addition), and CHO (Conditional Transfer), all based on L3 implementation. At the 94e plenary meeting of the 3GPP RAN, it was decided to initiate the standardization work item (Wl) for mobility enhancement technology based on an L1 / L2 (Layer 1 / Layer 2). The objective of the L1 / L2-based mobility enhancement technology design is to implement fast EU server cell switching. Considering the uplink synchronization requirements in mobility enhancement in an NR system, this application presents a solution.It should be noted that, in the description of the present application, mobility enhancement is considered only a typical application scenario or example; and the design in the present application is also applicable to other scenarios facing similar problems (e.g., other scenarios requiring uplink synchronization across a plurality of cells, including but not limited to multi-antenna systems, multi-TRP (Transmitter-Receiver Point) systems, capacity enhancement systems, short-range communication systems, unlicensed spectrum communication, IoT (Internet of Things), URLLC (Ultra-Reliable Low Latency Communication) networks, and Internet of Vehicles, etc.), in which similar technical effects can be achieved. Furthermore, adopting a unified solution across different scenarios (including but not limited to multi-carrier scenarios) can also help reduce hardware complexity and costs.In the absence of conflicts, 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.
