Description

A method and apparatus in a communication node used for wireless communication

[0001] This application claims priority to the Chinese Patent Application No. 202411252577.1, filed on September 6, 2024, entitled “A method and apparatus in a communication node used for wireless communication”, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to a transmission method and apparatus in a wireless communication system, in particular to a method and apparatus for conditional handover storage information. 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 R18, 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 instructions. SUMMARY

[0005] In the existing handover execution, if the storage condition is met and there is a conditional configuration, the existing SON storage mechanism will only store the relevant information of the candidate PCell; but in the case of CHO and CPC conditional candidate configuration, the information of PSCell and PCell is closely related, if only the candidate PCell information is stored, it will not be conducive to the optimization of CHO and CPC handover configuration, and further cause problems such as waste of configuration resources; therefore, how to store appropriate and efficient candidate PCell and PSCell information in the existing SON reporting variables, so that it can be more reasonably configured is a problem that needs to be solved in this research.

[0006] To solve the above problems, the present application provides a solution for conditional handover storage information. In the above problem description, NR system is taken as an example, but the present application is also applicable to scenarios such as LTE (Long-Term Evolution) or LTE-A (Long-Term Evolution Advanced) system or future 6G system, and similar technical effects of the NR system can be achieved. Further, although the present application gives specific implementation for the mobility of RRC_CONNECTED state involved in handover, it can also be used in scenarios such as RRC_IDLE state or RRC_INACTIVE state, and similar technical effects of the mobility of RRC connection state can be achieved. Further, although the present application gives specific implementation for the scenario of CHO and CPC handover, it can also be used in scenarios such as LTM and traditional handover, and similar technical effects of CHO and CPC handover can be achieved. 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 for Uu air interface, the present application can also be used for PC5 interface, and similar technical effects of the Uu air interface can be achieved. Further, although the original intention of the present application is for the terminal and base station scenario, the present application is also applicable to V2X (Vehicle-to-Everything) scenarios, terminal and relay, and communication scenarios between relay and base station, and similar technical effects in the terminal and base station scenario can be achieved. Further, although the original intention of the present application is for the terminal and base station scenario, the present application is also applicable to IAB (Integrated Access and Backhaul) communication scenarios, and similar technical effects in the terminal and base station scenario can be achieved. Further, although the original intention of the present application is for the TN (Terrestrial Network) scenario, the present application is also applicable to NTN (Non-Terrestrial Network) communication scenarios, and similar technical effects in the TN scenario can be achieved.

[0382] Embodiment 3

[0383] 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 of the data packets, and header compression. 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. The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating the various radio resources (e.g., resource blocks) in one 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 for the user plane 350 includes Layer 1 (LI layer) and Layer 2 (L2 layer), which are 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. Also included in the L2 layer 355 in the user plane 350 is the SDAP (Service Data Adaptation Protocol) sublayer 356, which is responsible for mapping between QoS flows and data radio bearers (DRBs) to support diverse service

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.

[0400] 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 by the receive processor 456, 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.

[0401] 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.

[0402] 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. Upper layer data packets from the controller / processor 475 can be provided to a core network.
