Description

TECHNICAL FIELD

[0001] The present application relates to a transmission method and device in a wireless communication system, in particular to a mobility information storage reporting method and device. BACKGROUND

[0002] Self-Organising Networks (SON) includes network self-configuration and self-optimization, which 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 (User Equipment, UE) to store and collect related information, and accompanies the availability and indication information of the stored and collected information to facilitate the base station to schedule the related information.

[0003] With the continuous development of wireless communication, the demand for mobility (Mobility) latency, robustness, etc. is getting higher and higher. In Release-16, 3GPP (the 3rd Generation Partnership Project, the 3rd Generation Partnership Project) introduces Conditional Handover (CHO) and CPC (Conditional PSCell (Primary SCG (Secondary Cell Group) Cell) Change), which allows the UE to perform mobility based on pre-configured execution conditions to shorten the handover interruption time. In Release-18, 3GPP launched the "NR (New Radio, New Radio) mobility further enhancement (Further NR mobility enhancements)" research project (Work Item, WI), and completed the standardization work of L1 (Layer 1) / L2 (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 in Release-19. The standardization of subsequent CPC makes subsequent CHO and subsequent LTM also become potential standardization directions. SUMMARY

[0004] In the conventional scheme, the UE stores the SuccessHO-Report or SuccessPSCell-Report and the like only when certain conditions are met, and the SuccessHO-Report or SuccessPSCell-Report stored and / or reported by the UE only supports the information of the source cell and the target / candidate cell. The inventors have found through research that the existing trigger conditions and contents for storing the SuccessHO-Report or SuccessPSCell-Report are not conducive to network optimization for subsequent CPC or subsequent CHO or subsequent LTM and the like, and therefore it is necessary to study the trigger conditions and / or contents for the report of the subsequent CPC or subsequent CHO or subsequent LTM.

[0005] To solve the above problems, the present application provides a solution for storing and reporting mobility information. In the above problem description, NR system is taken as an example, and the present application is also applicable to scenarios such as LTE (Long-Term Evolution) or LTE-A (Long-Term Evolution Advanced) or future 6G system, and similar technical effects of the NR system can be achieved. Further, although the present application mainly gives specific embodiments for the triggering conditions of the storage information reporting of the RRC_CONNECTED state, it can also be used in scenarios such as RRC_IDLE state or RRC_INACTIVE state, and similar technical effects of the storage information reporting of the RRC connection state for subsequent information can be achieved. Further, the unified design scheme for different scenarios can also help to reduce hardware complexity and cost. Further, although the present application gives specific embodiments for the CPC, LTM and CHO scenarios, it can also be used in scenarios such as m-TRP m-TA, and similar technical effects in the CPC, LTM and CHO scenarios can be achieved. Further, although the present application is initially intended for Uu air interface, it can also be used for PC5 interface, and similar technical effects of the Uu air interface can be achieved. Further, although the present application is initially intended for the terminal and base station scenario, it is also applicable to the V2X (Vehicle-to-Everything) scenario, the communication scenario between the terminal and the relay, and the communication scenario between the relay and the base station, and similar technical effects in the terminal and base station scenario can be achieved. Further, although the present application is initially intended for the terminal and base station scenario, it is also applicable to the IAB (Integrated Access and Backhaul) communication scenario, and similar technical effects in the terminal and base station scenario can be achieved. Further, although the present application is initially intended for the TN (Terrestrial Network) scenario, it is also applicable to the NTN (Non-Terrestrial Network) communication scenario, and similar technical effects in the TN scenario can be achieved. Further, although the present application is initially intended for the traditional communication waveform transmission scenario, it is also applicable to the transmission scenario combining communication and sensing waveforms, and similar technical effects in the traditional communication waveform transmission scenario can be achieved. In addition, the unified solution for different scenarios can also help to reduce hardware complexity and cost.

[0359] Example 3

[0360] 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 Fig. 3. Figure 3 Figure 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300, as shown in Fig. 3. Figure 3 ​The radio protocol architecture for controlling plane 300 is shown with 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 as the PHY 301 herein. Layer 2 (L2 layer) 305 is above the PHY 301 and includes a MAC (Medium Access Control) sublayer 302, a 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 ciphering the packets, and header compression. The RLC sublayer 303 provides segmentation and reassembly of upper layer packets, retransmission of lost packets, and reordering of 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 the various radio resources (e.g., resource blocks) in one cell. The MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3 layer) in the controlling plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling. The radio protocol architecture of the user plane 350 includes Layer 1 (L1 layer) and Layer 2 (L2 layer), which are substantially the same as the corresponding layers and sublayers in the controlling plane 300 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, 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 in the user plane 350, which is responsible for mapping between QoS flows and data radio bearers (DRBs) to support the diversity of services.

[0367] Example 4

[0368] Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to the present application, as shown in Fig. 4. Figure 4 The first communication device 450 and the second communication device 410 are block diagrams of the first communication device 450 and the second communication device 410, respectively, which are in communication with each other in an access network. Figure 4 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.

[0369] 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.

[0370]

[0371] ​In the transmission from the second communication device 410 to the first communication device 450, at the second communication device 410, upper layer packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements functionality of the L2 layer. In the transmission from the second communication device 410 to the first communication device 450, the controller / processor 475 provides header compression, ciphering, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocations for the first communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmissions of lost packets, and signaling. The transmit processor 416 and the multiple antenna transmit processor 471 implement various signal processing functions for the LI layer (i.e., physical layer). The transmit processor 416 implements coding and interleaving to facilitate forward error correction (FEC) at the second communication device 410, and mapping of coded and interleaved data onto various 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 multiple antenna transmit processor 471 performs digital spatial pre-coding of the coded and modulated symbols, including codebook-based and non-codebook-based pre-coding, and beamforming processing, to generate one or more spatial streams. The transmit processor 416 then maps to each spatial stream to the subcarriers, multiplexes the stream with reference signals (e.g., pilot) in the time and / or frequency domain, and then performs an inverse fast Fourier transform (IFFT) to generate a time-domain multicarrier symbol stream for the physical channel. The multiple antenna transmit processor 471 then performs transmit analog pre-coding / beamforming operations on the time-domain multicarrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multiple antenna transmit processor 471 into a radio frequency stream, and then provides the radio frequency stream to the corresponding antenna 420.

[0372] In transmissions from the second communication device 410 to the first communication device 450, at the first communication device 450, each receiver 454 receives a signal through its respective antenna 452. Each receiver 454 recovers information modulated onto an RF carrier and provides the recovered information at baseband as a stream of symbols to a receive processor 456. The receive processor 456 and a multiple access receiver processor 458 implement various signal processing functions of the Ll layer. The multiple access receiver processor 458 performs receive analog precoding / beamforming operations on the baseband multiple access symbol streams from the receivers 454. The receive processor 456 converts the baseband multiple access symbol streams from the time-domain to the frequency domain using a Fast Fourier Transform (FFT). In the frequency domain, the physical layer data signals and the reference signals are demultiplexed from the received symbol streams by the receive processor 456, with the reference signals to be used for channel estimation and the data signals to be recovered after multiple access detection in the multiple access receiver processor 458 for any spatial streams destined for the first communication device 450. The symbols on each spatial stream are demodulated and recovered by the receive processor 456 and used to generate soft decisions. The receive processor 456 then 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. The upper layer data and control signals are then provided to a controller / processor 459. The controller / processor 459 implements the functions of the L2 layer. The controller / processor 459 can be associated with a memory 460 that stores program codes and data. The memory 460 can be referred to as a computer-readable medium. In transmissions 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, deciphering, header decompression, 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 can also be provided to the L3 for L3 processing.

[0373] 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 upper layer data packets to a controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmit function 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, ciphering, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocations, implements L2 layer functionality for the user plane and control plane. The controller / processor 459 is also responsible for error detection, retransmission of lost packets, and signaling to the second communication device 410. A transmit processor 468 performs modulation mapping, 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, and then the transmit processor 468 modulates the resulting spatial streams into multi-carrier / single-carrier symbol streams, which are then provided to different antennas 452 via transmitters 454 after analog precoding / beamforming operations in the multi-antenna transmit processor 457. Each transmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmit processor 457 into a radio frequency signal, and then provides the radio frequency signal to the antenna 452.

[0374] 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 receive functions at the first communication device 450 described 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 respective 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 collectively implement the functionality of the L1 layer. A controller / processor 475 implements the functionality of the L2 layer. The controller / processor 475 can be associated with a memory 476 that stores program codes and data. The memory 476 can 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, deciphering, header decompression, control signal processing to recover upper layer data packets from the UE 450. Upper layer data packets from the controller / processor 475 can be provided to a core network.
