Description

Technical Field

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

[0002] Self-Organizing Networks (SON) include network self-configuration and self-optimization, can configure terminals to measure and collect key indicators, adaptively adjust parameters, and provide reliable support for optimizing mobility performance. The existing 3GPP protocol supports user equipment (UE) to store and collect relevant information, and reports the availability and indication information of the stored and collected relevant information along with the completion information, so that the base station can schedule the relevant information.

[0003] With the continuous development of wireless communications, the requirements for latency and robustness of mobility are getting higher and higher. In Release-16, 3GPP (the 3rd Generation Partnership Project) introduced Conditional Handover (CHO) and CPC (Conditional PSCell (PrimarySCG (Secondary Cell Group) Cell) Change), allowing UE mobility based on pre-configured execution conditions to shorten the 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 / L2Triggered Mobility, LTM) and subsequent CPC. Subsequent CPC will also become an important research direction of Release-19's SON / MDT EnhancementsWI. The standardization of subsequent CPC makes subsequent CHO and subsequent LTM also potential standardization directions. Summary of the invention

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

[0005] In response to the above problems, the present application provides a solution for storage and reporting of mobility information. In the description of the above problems, the NR system is used as an example. The present application is also applicable to scenarios such as LTE (Long-Term Evolution) or LTE-A (Long-Term Evolution Advanced) or future 6G systems, and achieves technical effects similar to those of the NR system; further, although the present application mainly provides a specific implementation method for trigger conditions for storage information reporting involving the RRC_CONNECTED state, the present application can also be used in scenarios such as the RRC_IDLE state or the RRC_INACTIVE state to achieve a technical effect similar to that of the storage and reporting of subsequent information in the RRC connection state. Furthermore, adopting a unified design scheme for different scenarios can also help reduce hardware complexity and cost. Furthermore, although the present application provides specific implementation methods for CPC, LTM and CHO scenarios, the present application can also be used in scenarios such as m-TRP m-TA to achieve technical effects similar to those in CPC, LTM and CHO scenarios. Further, 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 a technical effect similar to the Uu air interface. Further, 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 a technical effect similar to that in the terminal and base station scenario. Further, 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 a technical effect similar to that in the terminal and base station scenario. Further, although the original intention of this application is for the terrestrial network (Terrestrial Network, TN) scenario, this application is also applicable to the non-terrestrial network (Non-Terrestrial Network, NTN) communication scenario, to achieve a technical effect similar to that in the TN scenario. Furthermore, although the original intention of this application is for traditional communication waveform transmission scenarios, this application is also applicable to transmission scenarios combining communication and perception waveforms, achieving similar technical effects in traditional transmission scenarios. In addition, adopting a unified solution for different scenarios can also help reduce hardware complexity and cost.

[0360] Embodiment 3 shows a schematic diagram of an embodiment of a wireless protocol architecture of a user plane and a control plane according to the present application, as shown in the attached Figure 3 shown. Figure 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300, Figure 3The radio protocol architecture for the control plane 300 is shown in 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 PHY 301 in this article. 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 provides inter-zone mobility support. 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) in a 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 control plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and using RRC signaling to configure the lower layers. The radio protocol architecture of the user plane 350 includes layer 1 (L1 layer) and layer 2 (L2 layer). In the user plane 350, the radio protocol architecture is substantially the same as the corresponding layers and sublayers in the control 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 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), M-quadrature amplitude modulation (M-QAM)). The multi-antenna transmit processor 471 performs digital spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing 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 domain and / or frequency domain, and then uses an inverse fast Fourier transform (IFFT) to generate a physical channel carrying a time-domain multi-carrier symbol stream. The multi-antenna transmit processor 471 then performs a transmit analog precoding / beamforming operation 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 a different antenna 420.

[0372] 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 a signal through 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 and provides it to the receiving processor 456. The receiving processor 456 and the multi-antenna receiving processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiving processor 458 performs a receiving analog precoding / beamforming operation on the baseband multi-carrier symbol stream from the receiver 454. The receiving processor 456 uses a fast Fourier transform (FFT) to convert the baseband multi-carrier symbol stream after the receiving analog precoding / beamforming operation 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 receiving processor 456, wherein the reference signal will be used for channel estimation, and the data signal is recovered after multi-antenna detection in the multi-antenna receiving processor 458 to any spatial stream destined for the first communication device 450. The symbols on each spatial stream are demodulated and recovered in the receiving processor 456, and soft decisions are generated. The receiving 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 codes 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 multiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover the 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 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 the controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission 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, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocation, and implements L2 layer functions for user plane and control plane. The controller / processor 459 is also responsible for the retransmission of lost packets and signaling to the second communication device 410. The transmit processor 468 performs modulation mapping and channel coding processing, and the multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing. Then, the transmit processor 468 modulates the generated spatial stream into a multi-carrier / single-carrier symbol stream, which is then provided to different antennas 452 via the transmitter 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 symbol stream, and then provides it to the antenna 452.

[0374] In the transmission from the first communication device 450 to the second communication device 410, the function at the second communication device 410 is similar to the reception function 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 corresponding antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal to the multi-antenna reception processor 472 and the reception processor 470. The reception processor 470 and the multi-antenna reception processor 472 jointly implement the functions of the L1 layer. The controller / processor 475 implements the L2 layer functions. The controller / processor 475 can be associated with a memory 476 storing 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 multiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover the upper layer data packets from the UE 450. Upper layer packets from controller / processor 475 may be provided to the core network.
