Description

A method and apparatus for use in a communication node for wireless communication

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on January 15, 2024, with application number 202410059041.1 and invention name “A method and device in a communication node used for wireless communication”, and the Chinese patent application filed with the State Intellectual Property Office on January 15, 2024, with application number 202410581011.7 and invention name “A method and device in a communication node used for wireless communication”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to a transmission method and apparatus in a wireless communication system, and in particular to a method and apparatus for setting storage content of mobility information. Background Art

[0003] Self-Organizing Networks (SON) include network self-configuration and self-optimization. They can configure terminals to measure and collect key indicators and adaptively adjust parameters to provide reliable support for optimizing mobility performance. The existing 3GPP protocol supports user equipment (UE) to store and collect relevant information, and report the availability and indication of the stored and collected information along with the completion information to facilitate base station scheduling of related information.

[0004] With the continuous development of wireless communications, the requirements for mobility latency, robustness, etc. are becoming increasingly higher. In Release-16, 3GPP (the 3rd Generation Partnership Project) introduced Conditional Handover (CHO) and CPC (Conditional PSCell (Primary SCG (Secondary Cell Group) Cell) Change), allowing UE mobility based on pre-configured execution conditions to shorten handover interruption time. In Release-18, 3GPP launched the "NR (New Radio) Further NR mobility enhancements" research project (Work Item, WI) and completed the standardization of L1 (Layer 1, Layer 1) / L2 (Layer 2, Layer 2) triggered mobility (L1 / L2 Triggered Mobility, LTM) and subsequent CPC. Subsequent CPC will also become an important research direction of the SON / MDT Enhancements WI of Release-19. The standardization of subsequent CPC makes subsequent CHO and subsequent LTM also potential standardization directions. Summary of the Invention

[0005] In the traditional solution, the content of the SuccessHO-Report or SuccessPSCell-Report or RLF-report stored and / or reported by the UE only includes information about the source cell and the target / candidate cell, and the content setting of the SuccessHO-Report or SuccessPSCell-Report or RLF-report stored and / or reported by the UE is relatively single for mobility scenarios; the inventors found through research that the existing content settings for storing various types of reports are not conducive to network optimization for subsequent CPC or subsequent CHO or subsequent LTM, etc., and therefore it is necessary to study the settings for storing content in the reports of subsequent CPC or subsequent CHO or subsequent LTM.

[0006] To address the above issues, this application provides a solution for setting the storage content of mobility information. While the NR system is used as an example in the description of the above issues, this application is also applicable to scenarios such as LTE (Long-Term Evolution), LTE-A (Long-Term Evolution Advanced), or future 6G systems, achieving similar technical effects to those of the NR system. Furthermore, while this application primarily provides specific implementations for triggering conditions for reporting storage information in the RRC_CONNECTED state, this application can also be applied to scenarios such as the RRC_IDLE or RRC_INACTIVE states, achieving similar technical effects for setting the storage content of subsequent information in the RRC connected state. Furthermore, adopting a unified design for different scenarios also helps reduce hardware complexity and cost. Furthermore, while this application provides specific implementations for CPA / C, LTM, C-LTM, and CHO scenarios, this application can also be applied to scenarios such as m-TRP m-TA, achieving similar technical effects to those in CPA / C, LTM, C-LTM, and CHO scenarios. Furthermore, although the original intention of this application is for the Uu air interface, this application can also be used for the PC5 port to achieve technical effects similar to the Uu air interface. Furthermore, although the original intention of this application is for the terminal and base station scenario, this application is also applicable to the V2X (Vehicle-to-Everything) scenario, the communication scenario between the terminal and the relay, and the relay and the base station, to achieve technical effects similar to those in the terminal and base station scenario. Furthermore, although the original intention of this application is for the terminal and base station scenario, this application is also applicable to the IAB (Integrated Access and Backhaul) communication scenario, to achieve technical effects similar to those in the terminal and base station scenario. Furthermore, although the original intention of this application is for the terrestrial network (TN) scenario, this application is also applicable to the non-terrestrial network (NTN) communication scenario, to achieve technical effects similar to those in the TN scenario. Furthermore, while this application was originally intended for traditional communication waveform transmission scenarios, it is also applicable to transmission scenarios that combine communication and perception waveforms, achieving similar technical effects as in traditional communication waveform transmission scenarios. Furthermore, adopting a unified solution for different scenarios also helps reduce hardware complexity and costs.

[0326] Example 2

[0327] Embodiment 2 illustrates a schematic diagram of a network architecture according to an embodiment of the present application, as shown in FIG2 . FIG2 illustrates a network architecture 200 of a 5G NR (New Radio) / LTE (Long-Term Evolution) / LTE-A (Long-Term Evolution Advanced) system. The 5G NR / LTE / LTE-A network architecture 200 may be referred to as a 5G System (5G System) / EPS (Evolved Packet System) 200 or some other suitable terminology. The 5GS / EPS 200 includes at least one of a UE (User Equipment) 201, a RAN (Radio Access Network) 202, a 5G Core Network (5G Core Network) / EPC (Evolved Packet Core) 210, a Home Subscriber Server (HSS) / UDM (Unified Data Management) 220, and an Internet service 230. 5GS / EPS can interconnect with other access networks, but these entities / interfaces are not shown for simplicity. As shown, 5GS / EPS provides packet-switched services, but those skilled in the art will readily appreciate that the various concepts presented throughout this application can be extended to networks providing circuit-switched services or other cellular networks. The RAN includes node 203 and other nodes 204. Node 203 provides user and control plane protocol termination towards UE 201. Node 203 can be connected to other nodes 204 via an Xn interface (e.g., backhaul) / X2 interface. Node 203 may also be referred to as a base station, base transceiver station, radio base station, radio transceiver, transceiver function, basic service set (BSS), extended service set (ESS), TRP (transmitter / receiver node), or some other appropriate terminology. Node 203 provides an access point to the 5GC / EPC 210 for UE 201. Examples of UE 201 include a cellular phone, a smart phone, a Session Initiation Protocol (SIP) phone, a laptop computer, a personal digital assistant (PDA), a satellite radio, non-terrestrial base station communications, satellite mobile communications, a global positioning system, a multimedia device, a video device, a digital audio player (e.g., an MP3 player), a camera, a game console, a drone, an aircraft, a narrowband Internet of Things device, a machine type communication device, a land vehicle, an automobile, a wearable device, or any other similarly functional device.Those skilled in the art may also refer to UE 201 as a mobile station, subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, handset, user agent, mobile client, client, or some other appropriate term.

[0389] Example 3

[0390] Embodiment 3 illustrates 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 FIG3 . FIG3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300. FIG3 illustrates the radio protocol architecture for the control plane 300 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. The L1 layer will be referred to herein as PHY 301. Layer 2 (L2 layer) 305 is above PHY 301 and includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304. 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 supports inter-zone mobility. 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 out-of-order reception due to HARQ (Hybrid Automatic Repeat Request). 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) within a cell. The MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3) of the control plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and configuring lower layers using RRC signaling. The radio protocol architecture of the user plane 350 includes Layer 1 (L1) and Layer 2 (L2). The radio protocol architecture in the user plane 350 is generally identical to the corresponding layers and sublayers in the control plane 300, including 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. However, the PDCP sublayer 354 also provides header compression for upper layer packets to reduce radio transmission overhead. The L2 layer 355 in the user plane 350 also includes the SDAP (Service Data Adaptation Protocol) sublayer 356, which is responsible for mapping QoS flows to data radio bearers (DRBs) to support service diversity.

[0396] Example 4

[0397] Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to the present application, as shown in Figure 4. Figure 4 is a block diagram of a first communication device 450 and a second communication device 410 communicating with each other in an access network.

[0398] 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 , a multi-antenna transmit processor 457 , a multi-antenna receive processor 458 , a transmitter / receiver 454 and an antenna 452 .

[0399] The second communication device 410 includes a controller / processor 475 , a memory 476 , a receive processor 470 , a transmit processor 416 , a multi-antenna receive processor 472 , a multi-antenna transmit processor 471 , a transmitter / receiver 418 , and an antenna 420 .

[0400] During transmission from the second communication device 410 to the first communication device 450, upper layer data packets from the core network are provided to the controller / processor 475 at the second communication device 410. The controller / processor 475 implements L2 layer functionality. During 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 coding and interleaving to facilitate forward error correction (FEC) at the second communication device 410, as well as 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), and M-quadrature amplitude modulation (M-QAM)). The multi-antenna transmit processor 471 performs digital spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming on the coded and modulated symbols to generate one or more spatial streams. The transmit processor 416 then maps each spatial stream to a subcarrier, multiplexes it with a reference signal (e.g., a pilot) in the time and / or frequency domain, and then uses an inverse fast Fourier transform (IFFT) to generate a physical channel carrying the time-domain multicarrier symbol stream. The multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multicarrier 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 a different antenna 420.

[0401] During transmission from the second communication device 410 to the first communication device 450, at the first communication device 450, each receiver 454 receives a signal via its corresponding antenna 452. Each receiver 454 recovers the information modulated onto the RF carrier and converts the RF stream into a baseband multi-carrier symbol stream, which is provided to the receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 implement various L1 signal processing functions. The multi-antenna receive processor 458 performs receive analog precoding / beamforming operations on the baseband multi-carrier symbol stream from the receiver 454. The receive processor 456 converts the baseband multi-carrier symbol stream, after the receive analog precoding / beamforming operations, from the time domain to the frequency domain using a fast Fourier transform (FFT). In the frequency domain, the receive processor 456 demultiplexes the physical layer data signal and reference signal, where the reference signal is used for channel estimation. The data signal undergoes multi-antenna detection in the multi-antenna receive processor 458 to recover any spatial streams destined for the first communication device 450. The symbols on each spatial stream are demodulated and recovered in the receive processor 456, and soft decisions are generated. The receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper layer data and control signals transmitted by the second communication device 410 on the physical channel. The upper layer data and control signals are then provided to the controller / processor 459. The controller / processor 459 implements 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. During 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, and control signal processing to recover upper layer data packets from the core network. The upper layer data packets are then provided to all protocol layers above the L2 layer. Various control signals may also be provided to the L3 layer for L3 processing.

[0402] During transmission from the first communication device 450 to the second communication device 410, a data source 467 is used at the first communication device 450 to provide upper layer data packets to the controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission functionality at the second communication device 410 described 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, implementing L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for retransmission of lost packets and signaling to the second communication device 410. The transmit processor 468 performs modulation mapping and channel coding, while the multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming. The transmit processor 468 then modulates the resulting spatial stream into a multi-carrier / single-carrier symbol stream. After analog precoding and beamforming operations in the multi-antenna transmit processor 457, the stream is provided to different antennas 452 via the transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmit processor 457 into a RF symbol stream before providing it to the antenna 452.

[0403] During transmission from the first communications device 450 to the second communications device 410, the functionality at the second communications device 410 is similar to the reception functionality at the first communications device 450 described for transmission from the second communications device 410 to the first communications device 450. Each receiver 418 receives RF signals via its corresponding antenna 420, converts the received RF signals into baseband signals, and provides the baseband signals to a multi-antenna receive processor 472 and a receive processor 470. The receive processor 470 and the multi-antenna receive processor 472 collectively implement L1 layer functionality. A controller / processor 475 implements L2 layer functionality. The controller / processor 475 may be associated with a memory 476 storing program codes and data. The memory 476 may be referred to as a computer-readable medium. During transmission from the first communications device 450 to the second communications device 410, the controller / processor 475 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper layer data packets from the UE 450. Upper layer packets from controller / processor 475 may be provided to the core network.
