Description

Technical Field

[0001] This application relates to a method for terminal mobility in a wireless communication system and to the problem of saving signaling overhead in the configuration of measurement events. Background Art

[0002] The application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios pose different performance requirements on the system. To meet the different performance requirements of various application scenarios, it was decided at the 72nd plenary session of 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) to conduct research on the New Radio (NR) (or Fifth Generation, 5G) technology. At the 75th plenary session of 3GPP RAN, the WI (Work Item) of NR was adopted, and the standardization work of NR began.

[0003] In communication, whether it is LTE (Long Term Evolution) or 5G NR, it involves the accurate reception of reliable information, optimized energy efficiency ratio, determination of information effectiveness, flexible resource allocation, scalable system structure, efficient non-access stratum information processing, low service interruption and disconnection rates, support for low power consumption, which is of great significance for the normal communication between base stations and user equipment, for the reasonable scheduling of resources, and for the balance of system load. It can be said to be the cornerstone of high throughput, meeting the communication needs of various services, improving spectrum utilization, and improving service quality. It is indispensable for eMBB (enhanced Mobile BroadBand), URLLC (Ultra Reliable Low Latency Communication), or eMTC (enhanced Machine Type Communication). The L1 / L2 Triggered Mobility (LTM) technology is the latest research content of 3GPP R18, and its main purpose is to shorten the handover delay and interruption delay of the terminal in the mobile network, thereby enhancing the user experience. This technology aims at how to more effectively manage this mobility when the user equipment (such as a smart phone) moves from one cell to another in the mobile network, ensuring the continuity and quality of communication. In the traditional 5G New Radio (5G NR) network, the change of the serving cell is usually triggered by the measurement of layer 3 (L3) and completed through the radio resource control (RRC) reconfiguration signaling. This process involves a complete reset of layer 2 (L2) and layer 1 (L1), resulting in relatively long delays, greater overheads, and longer interruption times. The LTM technology aims to optimize this process by using L1 / L2 signaling, reducing delays, overheads, and interruption times. LTM is an important advancement in the field of mobile communication, which helps to improve the network performance and user experience, especially in high-speed mobile scenarios. Summary of the Invention

[0004] Researchers have found that in a wireless communication system, when a terminal needs to move between cells, how to more flexibly trigger and report mobility events and report the corresponding measurement results is a problem that needs to be solved.

[0005] In view of the above problems, the present application provides a solution. In the above problem description, the NR system is taken as an example, and the present application is also applicable to scenarios such as LTE (Long-Term Evolution), LTE-A (Long-Term Evolution Advanced), 5G+, or 6G systems, achieving technical effects similar to those of the NR system; further, although the present application gives specific implementation manners for LTM and CHO (Conditional Handover), the present application can also be used to solve other communication problems, such as network optimization, artificial intelligence, and mobility management; the method proposed in the present application is also very suitable for solving problems in network convergence scenarios. Further, adopting a unified design solution for different scenarios also helps to reduce hardware complexity and cost. Further, although the original intention of the present application is for the Uu air interface, the present application can also be used for the PC5 interface, achieving technical effects similar to those of the Uu air interface. Further, although the original intention of the present application is for the terminal-to-base station scenario, the present application is also equally applicable to the V2X (Vehicle-to-Everything) scenario, the communication scenarios between the terminal and the relay, and between the relay and the base station, achieving technical effects similar to those in the terminal-to-base station scenario. Further, although the original intention of the present application is for the terminal-to-base station scenario, the present application is also equally applicable to other communication scenarios, achieving technical effects similar to those in the terminal-to-base station scenario. Further, although the original intention of the present application is for the Terrestrial Network (TN) scenario, the present application is also equally applicable to the communication scenario of the Non-Terrestrial Network (NTN), achieving technical effects similar to those in the TN scenario. In addition, adopting a unified solution for different scenarios also helps to reduce hardware complexity and cost.

[0203] Example 3

[0204] Embodiment 3 shows a schematic diagram of an embodiment of a radio protocol architecture for a user plane and a control plane according to the present application, as shown in the appendix Figure 3 as follows. Figure 3 It is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300. Figure 3Show the radio protocol architecture of the control plane 300 for terminals (UE, gNB) and network nodes (gNB, UE), or between two UEs, using three layers: layer 1, layer 2, and layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (Physical Layer) signal processing functions. Layer 1 will be referred to as PHY301 in this article. Layer 2 (L2 layer) 305 is above PHY301 and is responsible for the link between the terminal and the network node and between two UEs through PHY301. Layer 2 305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, and these sublayers terminate at the network node. 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 for the terminal between network nodes. The RLC sublayer 303 provides segmentation and reassembly of upper layer data packets, retransmission of lost data packets, and reordering of data packets to compensate for disordered reception due to HARQ. The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) in a cell between terminals. 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 obtaining radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between the network node and the terminal. The radio protocol architecture of the user plane 350 includes layer 1 (L1 layer) and layer 2 (L2 layer). For the physical layer 351, the PDCP sublayer 354 in the L2 layer 355, the RLC sublayer 353 in the L2 layer 355, and the MAC sublayer 352 in the L2 layer 355, the radio protocol architecture for terminals and network nodes in the user plane 350 is generally the same as the corresponding layers and sublayers in the control plane 300, but the PDCP sublayer 354 also provides header compression for upper layer data packets to reduce radio transmission overhead. The SDAP (Service Data Adaptation Protocol) sublayer 356 is also included in the L2 layer 355 of the user plane 350, and the SDAP sublayer 356 is responsible for the mapping between QoS flows and data radio bearers (DRB, Data Radio Bearer) to support service diversity. The SRB can be regarded as a service or interface provided by the PDCP layer to higher layers, such as the RRC layer.In the NR system, the SRBs include SRB1, SRB2, and SRB3, which are respectively used to transmit different types of control signaling. The SRB is a bearer between the UE and the access network and is used to transmit control signaling including RRC signaling between the UE and the access network. SRB1 has special significance for the UE. After each UE establishes an RRC connection, there will be an SRB1 for transmitting RRC signaling. Most signaling is transmitted through SRB1. If SRB1 is interrupted or unavailable, the UE must perform RRC reconstruction; one SRB1 is established for each RRC connection. SRB2 is generally only used to transmit NAS signaling or signaling related to security; one SRB2 is established for each RRC connection. The UE may not be configured with SRB3. Except for emergency services, the UE must establish an RRC connection with the network to perform subsequent communication. Although not shown, the terminal may have several upper layers above the L2 layer 355. In addition, it also includes a network layer (e.g., IP layer) terminated at the P-GW on the network side and an application layer terminated at the other end of the connection (e.g., a remote UE, a server, etc.).

[0211] Example 4

[0212] Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to an embodiment of this application, as shown in the appendix Figure 4 shown. Figure 4 is a block diagram of a first communication device 450 and a second communication device 410 that communicate with each other in an access network.

[0213] The first communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmit processor 468, a receive processor 456, and optionally, a multi-antenna transmit processor 457, a multi-antenna receive processor 458, a transmitter / receiver 454, and an antenna 452.

[0214] The second communication device 410 includes a controller / processor 475, a memory 476, a receive processor 470, a transmit processor 416, and optionally, a multi-antenna receive processor 472, a multi-antenna transmit processor 471, a transmitter / receiver 418, and an antenna 420.

[0215] In the transmission from the second communication device 410 to the first communication device 450, at the second communication device 410, upper layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements the functionality of the L2 (Layer-2) layer. In the transmission from the second communication device 410 to the first communication device 450, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the first communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmission of lost packets and signaling to the first communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for the L1 layer (i.e., the physical layer). The transmit processor 416 implements encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 410, and mapping of signal constellations based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-phase shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM)). The multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, to generate one or more spatial streams. The transmit processor 416 then maps each spatial stream to subcarriers, multiplexes with reference signals (e.g., pilots) in the time domain and / or frequency domain, and then uses the inverse fast Fourier transform (IFFT) to generate a physical channel carrying a time-domain multi-carrier symbol stream. Subsequently, the multi-antenna transmit processor 471 performs transmit analog precoding / beamforming operations on the time-domain multi-carrier symbol stream. Each transmitter 418 converts the baseband multi-carrier symbol stream provided by the multi-antenna transmit processor 471 into a radio frequency stream, and then provides it to different antennas 420.

[0216] In the transmission from the second communication device 410 to the first communication device 450, at the first communication device 450, each receiver 454 receives signals via its respective antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multi-carrier symbol stream and provides it to the receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 perform various signal processing functions of the L1 layer. The multi-antenna receive processor 458 performs receive analog precoding / beamforming operations on the baseband multi-carrier symbol stream from the receivers 454. The receive processor 456 uses the fast Fourier transform (FFT) to convert the baseband multi-carrier symbol stream after the receive analog precoding / beamforming operations from the time domain to the frequency domain. In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receive processor 456, where the reference signal will be used for channel estimation, and the data signal recovers any spatial streams destined for the first communication device 450 after multi-antenna detection in the multi-antenna receive processor 458. The symbols on each spatial stream are demodulated and recovered in the receive processor 456, and soft decisions are generated. Subsequently, the receive processor 456 decodes and de-interleaves the soft decisions to recover the upper layer data and control signals transmitted by the second communication device 410 on the physical channel. Subsequently, the upper layer data and control signals are provided to the controller / processor 459. The controller / processor 459 performs the functions of the L2 layer. The controller / processor 459 may be associated with a memory 460 that stores program code and data. The memory 460 may be referred to as a computer-readable medium. In the transmission from the second communication device 410 to the second communication device 450, the controller / processor 459 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover upper layer data packets from the core network. Subsequently, the upper layer data packets are provided to all protocol layers above the L2 layer. Various control signals may also be provided to the L3 for L3 processing.

[0217] In the transmission from the first communication device 450 to the second communication device 410, at the first communication device 450, a data source 467 is used to provide an upper layer data packet to a controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission function described at the second communication device 410 in the transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocation, and implements L2 layer functions for the user plane and the control plane. The controller / processor 459 is also responsible for retransmitting lost packets and signaling to the second communication device 410. A transmit processor 468 performs modulation mapping and channel coding processing, and a multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing. Subsequently, the transmit processor 468 modulates the generated spatial streams into multi-carrier / single-carrier symbol streams, and after passing through an analog precoding / beamforming operation in the multi-antenna transmit processor 457, provides them to different antennas 452 via a transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmit processor 457 into a radio frequency symbol stream and then provides it to the antenna 452.

[0218] In the transmission from the first communication device 450 to the second communication device 410, the functions at the second communication device 410 are similar to the receiving functions described at the first communication device 450 in the transmission from the second communication device 410 to the first communication device 450. Each receiver 418 receives a radio frequency signal through its corresponding antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal to a multi-antenna receive processor 472 and a receive processor 470. The receive processor 470 and the multi-antenna receive processor 472 jointly implement L1 layer functions. A controller / processor 475 implements L2 layer functions. The controller / processor 475 may be associated with a memory 476 that stores program code and data. The memory 476 may be referred to as a computer-readable medium. In the transmission from the first communication device 450 to the second communication device 410, the controller / processor 475 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover the upper layer data packet from the UE 450. The upper layer data packet from the controller / processor 475 may be provided to the core network.
