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 in a communication node used for wireless communication. BACKGROUND

[0003] With the continuous development of wireless communication, the requirements for mobility, transmission delay and transmission capacity are becoming higher and higher, so technologies such as dual connectivity and carrier aggregation are introduced in 3GPP standards to expand the communication bandwidth. In R17, 3GPP allows the simultaneous inclusion of target MCG and target SCG in the configuration information of CHO candidate cells; in R18, 3GPP further enhances the dual connectivity scenario through the "Further NR mobility enhancements" research project (Work Item, WI) in the "Further NR mobility enhancements" research project (Work Item, WI), discusses carrying multiple candidate SCGs in one CHO condition configuration to support simultaneous evaluation of CHO and CPC, and completes the corresponding modification of protocol standardization.

[0004] Self-Organising Networks (SON) includes network self-configuration and self-optimization, in order to optimize mobility performance, realize fast handover (Handover) and reduce communication interruption, the existing protocol supports user equipment (User Equipment, UE) to store relevant handover information conducive to configuration optimization according to different handover completion conditions, and to report relevant storage information according to network indication. SUMMARY

[0005] After determining that the wireless connection fails, if the UE is configured with conditional handover, the UE will store the configuration information and measurement information of the cell selected at the time of wireless connection failure in the wireless connection failure report; the inventors have found through research that the existing storage content has less information storage for PSCell, and for the existing simultaneous evaluation of CHO and CPC scenario, increasing the storage information of PSCell is conducive to optimizing the network configuration of CHO with SCG(s); therefore, how to effectively store the relevant information of PSCell in the wireless connection failure report is a problem to be solved in this research.

[0006] To solve the above problems, the present application provides a solution. In the description of the above problems, the NR system is taken as an example, and 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 similar technical effects of the NR system are obtained; further, although the present application gives specific embodiments for the mobility of the RRC_CONNECTED state involved in the handover, the present application can also be used in scenarios such as the RRC_IDLE state or the RRC_INACTIVE state, and similar technical effects of the mobility of the RRC connection state are obtained. Further, although the present application gives specific embodiments for the CHO and CPC handover scenarios, the present application can also be used in scenarios such as LTM and traditional handover, and similar technical effects of CHO and CPC handover are obtained. Further, the unified design scheme for different scenarios also helps to reduce hardware complexity and cost. Further, although the original intention of the present application is to target the Uu air interface, the present application can also be used for the PC5 interface, and similar technical effects of the Uu air interface are obtained. Further, although the original intention of the present application is to target the terminal and base station scenario, the present application 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 are obtained. Further, although the original intention of the present application is to target the terminal and base station scenario, the present application is also applicable to the IAB (Integrated Access and Backhaul) communication scenario, and similar technical effects in the terminal and base station scenario are obtained. Further, although the original intention of the present application is to target the TN (Terrestrial Network) scenario, the present application is also applicable to the NTN (Non-Terrestrial Network) communication scenario, and similar technical effects in the TN scenario are obtained.

[0321] Embodiment 3

[0322] Figure 3 is a diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and the control plane 300. Figure 3 shows three layers for the radio protocol architecture for the control plane 300: Layer 1, Layer 2, and Layer 3. Layer 1 (LI layer) is the lowest layer and implements various PHY (Physical layer) signal processing functions. The LI 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 functions, such as ciphering / de-ciphering, and header compression / de-compression.

[0334] Embodiment 4

[0335] 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. FIG. 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.

[0336] 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.

[0337] The second communications 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 antennas 420.

[0338] In the transmission from the second communications device 410 to the first communications device 450, upper layer packets from a core network are provided to the controller / processor 475 at the second communications device 410. The controller / processor 475 implements functionality of the L2 layer. In the transmission from the second communications device 410 to the first communications device 450, the controller / processor 475 provides header compression, ciphering, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation for the first communications device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmission of lost packets, and signaling to the first communications device 450. The transmit processor 416 and the multi-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 communications device 410, and mapping of coded and modulated symbols onto resource elements (REs) for transmission. The multi-antenna transmit processor 471 performs digital spatial precoding of 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 transmit processor 416 then maps each spatial stream to a subcarrier, multiplexes the stream with reference signals (e.g., pilots), and then performs a Fast Fourier Transform (FFT) to generate a time-domain OFDM symbol stream. The multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations on the time-domain OFDM symbol stream. Each transmitter 418 converts the baseband OFDM symbol stream provided by the multi-antenna transmit processor 471 into a radio frequency (RF) signal that is transmitted via a respective antenna 420.

[0339] 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, 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.

[0340] 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.

[0341] 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.
