Description

[Technical Field]

[0001] This application relates to a transmission method and apparatus in a wireless communication system, and more particularly to a transmission method and apparatus for uplink synchronization in wireless communication. [Background technology]

[0002] In the future, the application scenarios for wireless communication systems will become increasingly diverse, and different application scenarios will require different performance requirements for the systems. To meet the different performance requirements in various application scenarios, the 72nd General Assembly of 3GPP (Third Generation Partner Projects) RAN (Radio Access Networks) decided to consider new radio (NR) (or 5G) technology, and at the 75th General Assembly of 3GPP RAN, a Work Items (WI) for new radio (NR) technology was approved, and standardization work for NR commenced.

[0003] In new wireless technologies, uplink synchronous transmission is one of the most fundamental requirements. 3GPP is working on developing uplink synchronous technology to adapt to various application scenarios and meet different needs. [Overview of the project]

[0004] When a User Equipment (UE) moves from the coverage range of one cell to the coverage range of another, the UE's serving cell must be changed, that is, the serving cell must be handed over from the source cell to the target cell. Changes to existing serving cells are typically triggered by L3 (Layer 3) measurements and implemented through synchronous reconfiguration triggered by RRC (Radio Resource Control) signaling. Serving cell changes implemented at L3 are characterized by significant delays, large signaling overhead, and long downtimes. To overcome these drawbacks, 3GPP (Third Generation Partner Project) RAN (Radio Access Network) introduced Dual Connectivity (DC), Conditional PSCell (Conditional PSCell (Primary SCG (Secondary Cell Group) Cell) Change, CPC), Conditional PSCell Addition (CPA), Conditional Handover (CHO), and other technologies in Rel (Release) 17, all of which are implemented based on L3. At the 94th General Assembly of 3GPP RAN, it was decided to initiate work on the standardization of a Work Item (WI) for mobility augmentation technology based on L1 / L2 (Layer 1 / Layer 2). The design goal of mobility augmentation technology based on L1 / L2 is to implement high-speed handover of UE serving cells. In response to the requirement for uplink synchronization of mobility augmentation in NR systems, this application discloses one solution. In the description of this application, mobility augmentation is used only as one typical application scenario or example, and the design of this application is also applicable to other scenarios facing similar problems (including, but not limited to, multi-antenna systems, multi-TRP (transmitter-receiver-point) systems, capacity expansion systems, short-range communication systems, communications in the unlicensed frequency domain, IoT (Internet of Things), URLLC (ultra-high reliability low-latency communication) networks, and the Internet of Vehicles, as well as other scenarios requiring multi-cell uplink synchronization), and similar technical effects can be achieved. Furthermore, using a unified solution for different scenarios (including, but not limited to, multi-carrier scenarios) also helps to reduce hardware complexity and cost.When there is no contradiction, the embodiments and features of the embodiments in the first node device of the present application can also be applied to the second node device, and vice versa.

Layer 1 (L1 layer) is the lowest layer and implements various PHY (physical layer) signal processing functions. Layer L1 is referred to herein as PHY 301. Layer 2 (L2 layer) 305 is above PHY 301 and is responsible for the link between the first node device and the second node device via PHY 301. Layer L2 305 includes MAC (Media Access Control) sublayer 302, RLC (Radio Link Control) sublayer 303, and PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the second node device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security by encrypting data packets and provides handover support between the second node device to the first node device. The RLC sublayer 303 compensates for disruption of the reception order caused by HARQ by providing splitting and reassembly of upper-layer data packets, retransmission of lost data packets, and reordering of data packets. The MAC sublayer 302 provides multiplexing between logical channels and transport channels. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a single cell between the first node devices. The MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in layer 3 (L3 layer) of the control plane 300 is responsible for acquiring radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between the second node device and the first node device.The wireless protocol architecture of the user plane 350 comprises Layer 1 (L1 layer) and Layer 2 (L2 layer). The wireless protocol architecture of the first and second node devices in the user plane 350 is substantially the same as the corresponding layers and sublayers in the control plane 300 for the physical layer 351, PDCP sublayer 354 within L2 layer 355, RLC sublayer 353 within L2 layer 355, and MAC sublayer 352 within L2 layer 355, except that the PDCP sublayer 354 also provides header compression for upper-layer data packets to reduce wireless transmission overhead. The L2 layer 355 in the user plane 350 also includes an SDAP (Service Data Adaptive Protocol) sublayer 356, which is responsible for mapping between QoS flows and data radio bearers (DRBs) to support service diversity. Although not shown in the diagram, the first node device is...

The transmitted data or control is recovered and then provided to the controller / processor 490. The controller / processor 490 is responsible for the L2 layer and the layers above it, and the controller / processor 490 interprets the higher-level information contained in the first information block of this application. The controller / processor may be associated with a memory 480 that stores program code and data. The memory 480 may be referred to as a computer-readable medium.

[0221] In uplink (UL) transmission, as in downlink transmission, high-layer information is generated by the controller / processor 490 and then implemented by the transmission processor 455 for various signal transmission processing functions for the L1 layer (i.e., the physical layer). Specifically, the generation of the first signal is completed by the transmission processor 455, and the first signal is then mapped by the transmission processor 455 to the antenna 460 via the transmission device 456 and transmitted in the form of a radio frequency signal. The receiving device 416 receives the radio frequency signal via the corresponding antenna 420, and each receiving device 416 reconstructs the baseband information modulated on the radio frequency carrier and provides the baseband information to the receiving processor 412. The receiving processor 412 implements various signal reception processing functions for the L1 layer (i.e., the physical layer), including receiving and processing the first signal, and then provides data and / or control signals to the controller / processor 440.
