Description

Technical Field

[0001] This application relates to a transmission method and apparatus in a wireless communication system, and particularly to a method and apparatus for storing a wireless connection failure report. Background Art

[0002] With the continuous development of wireless communication, the requirements for mobility, transmission latency, and system capacity are getting higher and higher. At the 3GPP #94e meeting, it was decided to study L1 / L2 Triggered Mobility (LTM) in the "Further NR mobility enhancements" Work Item (WI) of the "NR (New Radio) mobility further enhancements" research project. Therefore, in the case of fast handover, in order to reduce transmission latency and improve mobility performance, the base station needs to obtain more available information to schedule relevant information more accurately and quickly.

[0003] Self-Organising Networks (SON) include network self-configuration and self-optimization. To optimize mobility performance, achieve fast handover, and reduce communication interruptions, existing protocols support User Equipment (UE) to store relevant handover information beneficial to configuration optimization according to different handover completion situations, and report the stored information according to network instructions. Summary of the Invention

[0004] After determining a wireless connection failure, the UE clears the content in the current wireless connection failure report and stores the cell information and relevant configuration information where the current wireless connection failure occurs. The inventors found through research that the existing stored content and storage mechanism are not applicable to the information storage and optimization of existing subsequent configurations, cannot support scenarios of continuous failures, cannot ensure the effectiveness and relevance of information, and are prone to loss of stored information. Therefore, how to improve the efficiency of network optimization and the effectiveness of reported information in the scenario of continuous failures is a problem to be solved in this study.

[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. The present application is also applicable to scenarios such as the LTE (Long-Term Evolution) or LTE-A (Long-Term Evolution Advanced) system or the future 6G system, and achieves technical effects similar to those of the NR system. Further, although the present application gives specific implementation manners for the mobility in the RRC_CONNECTED state involved in handover, the present application can also be used in scenarios such as the RRC_IDLE state or the RRC_INACTIVE state, and achieves technical effects similar to the mobility in the RRC connected state. Further, although the present application gives specific implementation manners for the scenario of LTM handover, the present application can also be used in scenarios such as C-LTM, CHO, and SCPAC, and achieves technical effects similar to those of LTM handover. Further, adopting a unified design solution for different scenarios also helps to reduce the 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 and achieves technical effects similar to those of the Uu air interface. Further, although the original intention of the present application is for the scenario of the terminal and the base station, 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, and achieves technical effects similar to those in the scenario of the terminal and the base station. Further, although the original intention of the present application is for the scenario of the terminal and the base station, the present application is also equally applicable to the communication scenario of IAB (Integrated Access and Backhaul) and achieves technical effects similar to those in the scenario of the terminal and the base station. Further, although the original intention of the present application is for the scenario of the terrestrial network (TN), the present application is also equally applicable to the communication scenario of the non-terrestrial network (NTN) and achieves technical effects similar to those in the TN scenario.

[0205] As an example, the non - setting of the previousPCellId field in the first information block depends on the second field.

[0206] As an example, the non - setting of the previousPCellId field in the first information block depending on the second field means that if the second field is set, the previousPCellId field is not set in the first information block.

[0373] Example 3

[0374] 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 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 controlling 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 PHY301 herein. Layer 2 (L2 layer) 305 is above PHY301 and includes a MAC (Medium Access Control) sub-layer 302, an RLC (Radio Link Control) sub-layer 303, and a PDCP (Packet Data Convergence Protocol) sub-layer 304. The PDCP sub-layer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sub-layer 304 also provides security by encrypting data packets and provides handover support. The RLC sub-layer 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 (Hybrid Automatic Repeat Request). The MAC sub-layer 302 provides multiplexing between logical and transport channels. The MAC sub-layer 302 is also responsible for allocating various radio resources (e.g., resource blocks) in a cell. The MAC sub-layer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sub-layer 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. 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 generally the same as the corresponding layers and sub-layers in the control plane 300 for the physical layer 351, the PDCP sub-layer 354 in the L2 layer 355, the RLC sub-layer 353 in the L2 layer 355, and the MAC sub-layer 352 in the L2 layer 355. However, the PDCP sub-layer 354 also provides header compression for upper layer data packets to reduce radio transmission overhead. The L2 layer 355 in the user plane 350 also includes an SDAP (Service Data Adaptation Protocol) sub-layer 356. The SDAP sub-layer 356 is responsible for mapping between QoS flows and data radio bearers (DRBs) to support service diversity.

[0386] Example 4

[0387] Example 4 shows a schematic diagram of a first communication device and a second communication device according to this application, as shown in the appendix Figure 4 as 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.

[0388] 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.

[0389] The second communication device 410 includes a controller / processor 475, a memory 476, a receiving processor 470, a transmitting processor 416, a multi-antenna receiving processor 472, a multi-antenna transmitting processor 471, a transmitter / receiver 418, and an antenna 420.

[0390] In a 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 L2 layer functionality. In a 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 for 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 transmitting processor 416 and the multi-antenna transmitting processor 471 implement various signal processing functions for the L1 layer (i.e., the physical layer). The transmitting processor 416 implements coding 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 transmitting processor 471 performs digital spatial precoding on the coded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, to generate one or more spatial streams. The transmitting 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 transmitting processor 471 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 transmitting processor 471 into a radio frequency stream, and then provides it to different antennas 420.

[0391] 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.

[0392] 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 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 retransmission of lost packets and signaling to the second communication device 410. A transmit processor 468 performs modulation mapping and channel coding processing. 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 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.

[0393] 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 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 radio frequency signals through its corresponding antenna 420, converts the received radio frequency 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 jointly implement the L1 layer functions. A controller / processor 475 implements the 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 upper layer data packets from the UE 450. The upper layer data packets from the controller / processor 475 may be provided to the core network.
