Description

Technical Field

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

[0002] With the continuous development of wireless communication, the requirements for mobility, transmission delay, and transmission capacity are getting higher and higher. Therefore, technologies such as dual connectivity and carrier aggregation are introduced in the 3GPP standard to expand the communication bandwidth. In R17, 3GPP allows the configuration information of the target MCG and the target SCG to be included in the configuration information of the CHO candidate cell at the same time; in R18, 3GPP further enhances the dual-connectivity scenario through the "Further NR mobility enhancements" work item in the "NR (New Radio) mobility" study project, discusses carrying multiple candidate SCGs in a CHO condition configuration to support the simultaneous evaluation of CHO and CPC, and completes the corresponding modification of protocol standardization.

[0003] Self-Organising Networks (SON) include network self-configuration and self-optimization. To optimize the mobility performance, achieve fast handover, and reduce communication interruption, the existing protocol supports the user equipment (UE) to store relevant handover information beneficial to configuration optimization according to different handover completion situations, and report the relevant stored information according to the network indication. Summary of the Invention

[0004] After determining a wireless connection failure, if the UE is configured with conditional handover, the UE will store the configuration information and measurement information of the candidate cell at the time of the wireless connection failure in the wireless connection failure report; the inventor has found through research that the existing stored content stores less information about the PSCell. For the existing scenario of simultaneously evaluating CHO and CPC, increasing the stored information of the PSCell is beneficial to optimizing the network configuration for CHO with SCG(s); therefore, how to effectively store the relevant information of the PSCell in the wireless connection failure report is a problem to be solved in this research.

[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 can achieve 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 can achieve technical effects similar to the mobility in the RRC connected state. Further, although the present application gives specific implementation manners for the scenarios of CHO and CPC handover, the present application can also be used in scenarios such as LTM and traditional handover, and can achieve technical effects similar to those of CHO and CPC handover. Further, adopting a unified design scheme 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 can achieve 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 can achieve 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 can achieve 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 terrestrial network (TN) scenario, the present application is also equally applicable to the non-terrestrial network (NTN) communication scenario, and can achieve technical effects similar to those in the TN scenario.

[0326] Example 3

[0327] 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 2 (L2 layer) 305 is above PHY301 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.

[0339] Example 4

[0340] Embodiment 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 It 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.

[0341] 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.

[0342] 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.

[0343] 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 the functionality of the L2 layer. 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 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 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 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 transmitting processor 471 into a radio frequency stream, and then provides it to different antennas 420.

[0344] 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 corresponding 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 that is provided 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 deinterleaves 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.

[0345] In the transmission from the first communication device 450 to the second communication device 410, at the first communication device 450, the 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 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 the 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. The transmit processor 468 performs modulation mapping and channel coding processing. The 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 the analog precoding / beamforming operation in the multi-antenna transmit processor 457, provides them 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 radio frequency symbol stream and then provides it to the antenna 452.

[0346] 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 radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals into baseband signals, and provides the baseband signals to the multi-antenna receive processor 472 and the receive processor 470. The receive processor 470 and the multi-antenna receive processor 472 jointly implement the L1 layer functions. The 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.
