Description

Technical Field

[0001] This application relates to transmission methods and apparatuses in a wireless communication system, and particularly to methods and apparatuses for storing radio link failure reports. 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 have been introduced in the 3GPP standard to expand the communication bandwidth and provide users with higher rates. For example, in the Dual Connectivity (DC) technology, a User Equipment (UE) can access two networks simultaneously; in a Multi-Path (MP) scenario, the UE is configured with a direct path and an indirect path, and the UE can establish a connection with the network through both the direct path and the indirect path.

[0003] Self-Organising Networks (SON) include network self-configuration and self-optimization. To optimize the mobility performance, achieve fast handover, and reduce communication interruptions, existing protocols support the UE to store information about relevant radio connection failures in the radio link failure report after determining that a radio connection failure has occurred, and report the stored information according to network instructions.

[0004] The network can notify the MN of a radio link failure by starting a fast MCG failure recovery procedure to achieve fast MCG recovery and reduce the link interruption time; after Release 18, the UE supports fast MCG failure recovery in both the dual connectivity and MP scenarios, and supports storing and reporting information during the fast MCG recovery process in the radio link failure report. Summary of the Invention

[0005] After starting the fast MCG failure recovery procedure, the UE stores the cell identifier of the SCG connected during the fast MCG failure recovery and other relevant information in the radio link failure report according to the specific MCG recovery situation; the inventors have found through research that if the MCG link connection is restored through another path in the MP scenario, storing the relevant information of the fast MCG failure recovery in the radio link failure report has little value for network optimization and there is a problem of occupying storage resources; therefore, optimizing the storage conditions of the relevant information in the radio link failure report for the fast MCG failure recovery scenario is a problem to be solved in this research.

[0006] 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, and the present application is also applicable to scenarios such as the LTE (Long-Term Evolution) system, the LTE-A (Long-Term Evolution Advanced) system, or the future 6G system, achieving 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 related to handover, the present application can also be used in scenarios such as the RRC_IDLE state or the RRC_INACTIVE state, achieving technical effects similar to the mobility in the RRC connected state. 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, achieving 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, achieving 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), achieving 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, achieving technical effects similar to those in the TN scenario.

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.

[0319] Example 4

[0320] 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 follows. 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.

[0321] 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.

[0322] 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.

[0323] In the transmission from the second communication device 410 to the first communication device 450, at the second communication device 410, the upper layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements the functions 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, 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 the retransmission of lost packets and signaling to the first communication device 450. 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 encoding 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 transmit processor 471 performs digital spatial precoding on the encoded 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 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 transmit 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 transmit processor 471 into a radio frequency stream and then provides it to different antennas 420.

[0324] 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.

[0325] 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, which are then provided to different antennas 452 via a transmitter 454 after an analog precoding / beamforming operation 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.

[0326] 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 function 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.
