Description

Method and apparatus for determining serving cells used in wireless communication Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to methods and apparatus for determining serving cells. Background Technology

[0002] For UEs in the RRC_CONNECTED state, the serving cell includes the PCell (Primary Cell) and the PSCell (Primary SCG (Secondary Cell Group) Cell). For UEs in the RRC_INACTIVE or RRC_IDLE states, the serving cell is the cell where the UE is camped. To ensure UE mobility performance, the UE can perform PCell handover and PSCell change in the RRC_CONNECTED state, and can perform cell selection or cell re-selection in the RRC_INACTIVE or RRC_IDLE states.

[0003] In NR Release 18, research on AI (Artificial Intelligence) / ML (Machine Learning) technologies was initiated to explore their impact on system performance and system design. 3GPP Release 19 launched the WI: "AI (Artificial Intelligence) / ML (Machine Learning) for NR Air Interface," supporting a general AI / ML architecture that supports one-sided AI / ML models. Compared to traditional processing methods, AI / ML offers advantages such as training-based and deployment-required characteristics. Considering the potential of AI (Artificial Intelligence) / ML (Machine Learning) algorithm-based mechanisms to achieve proactive solutions, and the related progress in AI / ML based on RAN1 and RAN3, 3GPP (the 3rd Generation Partnership Project) adopted a Study Item (SI) entitled "Study on AI / ML for mobility in NR," to investigate and evaluate the potential benefits and advantages of AI / ML-assisted mobility for network-triggered L3-based handover. Furthermore, AI / ML is also a key candidate technology for future 6G communications.

[0004] Since the specifications of AI models may extend beyond the scope of 3GPP (except for reference models used for performance calibration), the specific implementation of AI / ML training and AI / ML inference may be determined by the hardware equipment vendors themselves. It may be based on classic models such as Transformer architecture, RNN (Recurrent Neural Network), CNN (Conventional Neural Networks), or a hybrid model composed of multiple models.

[0005] Timing advance is used to adjust the uplink frame timing relative to the downlink frame timing. According to TS 38.300, in existing 5G (5th Generation Mobile Communication Technology) NTN (Non-Terrestrial Network) systems, to obtain Timing Advance (TA), valid ephemeris information and common TA parameters are broadcast via the network. Before connecting to an NTN cell, the UE should have valid GNSS position, ephemeris information, and common TA parameters. For synchronization, before or during access to an NTN cell, the UE should calculate the RTT between the UE and the Reference Point (RP) based on the GNSS position, ephemeris information, and common TA parameters, and autonomously pre-compensate the TTA for the RTT between the UE and the RP.

[0006] The ITU (International Telecommunication Union) proposed the requirements and use cases for 6G (6th Generation Mobile Communication Technology) in its recommendation "Framework and overall objectives of the future development of IMT for 2030 and beyond". Among them, ubiquitous connectivity is an important use case, which aims to enhance connectivity to bridge the digital divide. A key focus of this use case is to address areas that currently have no coverage or almost no coverage. In addition, 3GPP has also begun to study 6G use cases. In TR 22.870, a use case on resilient positioning in satellite networks was proposed for ubiquitous connectivity. This use case takes into account that positioning, navigation, and timing (PNT) are fundamental to a wide range of sectors such as transportation, critical infrastructure (such as 6G systems), and emergency services. If GNSS is unavailable or interrupted, these sectors’ reliance on GNSS will certainly pose a significant threat and risk. For 6G NTN, integrated communication and positioning systems can provide GNSS-independent positioning solutions for 6G NTN communication. Summary of the Invention

[0007] In existing technologies, whether a cell is identified as a serving cell depends on the cell's reception quality. The inventors discovered through research that existing methods for determining serving cells are not suitable for AI scenarios. Therefore, determining the serving cell in AI scenarios is a necessary technical problem to solve.

[0008] As an example, the interpretation of terms in this application is based on the definitions in the 3GPP specification protocol TS38 series.

[0010] It should be noted that, unless otherwise specified, the embodiments and features in any node of this application can be applied to any other node. Furthermore, unless otherwise specified, the embodiments and features in any embodiment of this application can be arbitrarily combined with each other.

[0011] This application discloses a method used in a first node for wireless communication, characterized by comprising:

[0013] Determine the service area;

[0014] Wherein, each data set indicated by the first identifier set is applied to the first cell, and whether the first cell is determined to be the serving cell depends on the first identifier set and the second identifier set; each identifier in the second identifier set indicates a data set, and each data set indicated by the second identifier set is used for AI, and the second identifier set is obtained before receiving the first signaling.

[0015] Given the significant overhead of the data set used for AI, when determining the serving cell based on existing technologies, if the selected serving cell cannot or cannot promptly utilize the data set already obtained for AI, the UE may not be able to fully leverage the gains brought by AI, further impacting the UE's service performance. The aforementioned method, regarding whether the first cell is determined as the serving cell, considers the influence of the first identifier set and the second identifier set, which helps improve the continuity of the data set used for AI, fully utilizes the gains brought by AI, selects a more suitable serving cell for the UE, and further improves the UE's service performance.

[0016] According to one aspect of this application, the determination of the serving cell includes: selecting the serving cell from a plurality of cells; the plurality of cells includes the first cell; and the reception quality of each of the plurality of cells meets the service requirements.

[0017] The above method takes into account the UE's service quality and further limits the selection of the serving cell from multiple cells whose reception quality meets the service requirements, thereby avoiding link problems in the serving cell.

[0018] According to one aspect of this application, the determination of whether the first cell is the serving cell depends on the first identifier set and the second identifier set, including: if the second identifier set and the first identifier set have a non-empty intersection, the first cell is preferentially selected.

[0019] The above method is simple to implement.

[0020] According to one aspect of this application, the first identifier set and the second identifier set each include multiple identifiers; the larger the number of identifiers included in the intersection of the second identifier set and the first identifier set, the more preferentially the first cell is selected.

[0040] According to one aspect of this application, the first signaling is received in the RRC_CONNECTED state. The above method is beneficial for improving mobility performance in the RRC_CONNECTED state.

[0041] This application discloses a method used in a second node for wireless communication, characterized by comprising:

[0042] Send a first signaling message; wherein the first signaling message indicates a first set of identifiers, each identifier in the first set of identifiers indicates a data set, and each data set indicated by the first set of identifiers is used for AI;

[0043] Wherein, each data set indicated by the first identifier set is applied to the first cell, and whether the first cell is determined as the serving cell by the receiver of the first signaling depends on the first identifier set and the second identifier set; each identifier in the second identifier set indicates a data set, and each data set indicated by the second identifier set is used for AI, and the second identifier set is obtained by the receiver of the first signaling before receiving the first signaling.

[0044] According to one aspect of this application, the receiver of the first signaling selects the serving cell from a plurality of cells; the plurality of cells includes the first cell; and the reception quality of each of the plurality of cells meets the service requirements.

[0045] According to one aspect of this application, the determination of whether the first cell is the serving cell by the receiver of the first signaling depends on the first identifier set and the second identifier set, including: if the second identifier set and the first identifier set have a non-empty intersection, the first cell is preferentially selected.

[0046] According to one aspect of this application, the first identifier set and the second identifier set each include multiple identifiers; the larger the number of identifiers included in the intersection of the second identifier set and the first identifier set, the more preferentially the first cell is selected.

[0047] According to one aspect of this application, it is characterized by comprising:

[0048] Receive second signaling;

[0049] The second signaling indicates the second set of identifiers.

[0050] According to one aspect of this application, it is characterized by comprising:

[0054] A first processor receives a first signaling instruction; wherein the first signaling instruction indicates a first set of identifiers, each identifier in the first set of identifiers indicates a data set, and each data set indicated by the first set of identifiers is used for AI.

[0055] The first processor determines the serving cell;

[0060] In existing NTN systems, the transmission time of uplink physical layer information depends on the UE's support for GNSS (Global Navigation Satellite System) capabilities and its possession of a valid GNSS location. If the UE does not have a valid GNSS location and / or valid ephemeris information and common TA parameters, it should not transmit information until this information is reacquired. Therefore, for UEs that do not support GNSS or have not acquired a valid GNSS location, determining the transmission time of uplink physical layer information is a technical problem that needs to be solved.

[0061] To address the aforementioned problems, this application provides a solution. While the uplink physical layer information transmission time is used as an example in the problem description, this application is also applicable to the transmission time of physical layer information such as sidelink (SL) or IAB (Integrated Access and Backhaul) physical layer information, achieving a similar technical effect to the uplink physical layer information transmission time. Furthermore, although the initial purpose of this application is to obtain the uplink physical layer information transmission time, the proposed technical solution is also applicable to obtaining the UE's location to enhance the UE's positioning function, especially providing positioning services for UEs that do not support GNSS or have not obtained a valid GNSS location. Furthermore, although the initial purpose of this application is for scenarios where the UE does not support GNSS or has not obtained a valid GNSS location, this application is also applicable to UEs that support GNSS and have obtained a valid GNSS location, to obtain better positioning services or more accurate transmission time.

[0062] This application discloses a method used in a first node for wireless communication, characterized by comprising:

[0063] Receive the first signaling, which configures the timing for transmitting the first ephemeris and the first reference signal;

[0064] Receive the first reference signal;

[0065] Send first physical layer information;

[0066] The transmission time of the first physical layer information depends on the difference between the transmission timing and the reception timing of the first reference signal; the transmission timing of the first reference signal is associated with the first ephemeris.

[0067] Regarding how to determine the transmission time of the first physical layer information, the above method utilizes the difference between the transmission timing and the reception timing of the first reference signal to obtain the transmission time of the first physical layer information, which is beneficial for uplink transmission of UEs that do not support GNSS or have not obtained a valid GNSS location.

[0068] Furthermore, regarding how to configure the transmission timing of the first reference signal, the above method configures the transmission timing of the first ephemeris and the first reference signal through the first signaling. The transmission timing of the first reference signal is associated with the first ephemeris, which solves the above problem and facilitates the first node in determining the transmission timing of the first reference signal and obtaining the satellite's position information, making the implementation simple.

[0069] According to one aspect of this application, it is characterized by comprising:

[0070] Determine the first timing advance;

[0072] The above method is conducive to compatibility with existing standards.

[0073] According to one aspect of this application, the first signaling configures the transmission timing of each of the K1 ephemeris and K1 reference signals; the transmission timing of each of the K1 reference signals is associated with one of the K1 ephemeris; the transmission timings of any two of the K1 reference signals are associated with different ephemeris; the first reference signal is any one of the K1 reference signals; and K1 is an integer greater than 1.

[0074] As an example, the K1 reference signals are transmitted by the same person.

[0075] The above method is simple to implement compared to associating the transmission timing of each of the K1 reference signals with the first ephemeris.

[0076] As one example, the K1 reference signals are transmitted by different senders.

[0077] Compared with using a single satellite, the above method is beneficial for improving positioning accuracy or the accuracy of the transmission time of the first physical layer information.

[0078] According to one aspect of this application, the first signaling configures the transmission timing of each of the K1 reference signals; the transmission timing of each of the K1 reference signals is associated with the first ephemeris; the first reference signal is any one of the K1 reference signals; and K1 is an integer greater than 1.

[0079] The above method, compared with associating the transmission timing of each of the K1 reference signals with one of the K1 ephemeris, helps to reduce signaling overhead.

[0080] According to one aspect of this application, it is characterized by comprising:

[0081] Determine the position of the first node;

[0082] Wherein, determining the position of the first node depends on the difference between the transmission timing of each of the K1 reference signals and the reception timing of the corresponding reference signal; the transmission time of the first physical layer information depends on the position of the first node and the second ephemeris.

[0083] Regarding how to determine the location of the first node, the above method uses the difference between the transmission timing of each of the K1 reference signals and the reception timing of the corresponding reference signal to obtain the location of the first node. This method does not rely on GNSS and is beneficial for enhancing the positioning of the first node.

[0084] The above method uses the difference between the transmission timing of each of the K1 reference signals and the reception timing of the corresponding reference signal to determine the transmission time of the first physical layer information, which enhances the positioning of the first node and is beneficial to the uplink transmission of UEs that do not support GNSS or have not obtained a valid GNSS location.

[0085] According to one aspect of this application, the time interval between the earliest and latest reference signals among the K1 reference signals is not greater than a first time length.

[0086] Considering that the movement of the UE and the satellite will cause the satellite and the UE to have different positions at different times, the above method avoids the impact of the movement of the UE or the satellite on the determination of the position of the first node or the transmission time of the first physical layer information by using the first time length.

[0087] According to one aspect of this application, the first signaling indicates a first system frame, and the transmission timing of the first reference signal depends on the first system frame.

[0088] The above method takes into account that the system frame has a timing function. Using the system frame to determine the transmission timing of the first reference signal is beneficial to protocol implementation and protocol compatibility.

[0089] According to one aspect of this application, the first signaling indicates a first Coordinated Universal Time (UTC), and the transmission timing of the first reference signal depends on the first UTC.

[0090] The above method uses Coordinated Universal Time (UTC) to determine the transmission timing of the first reference signal, avoiding system frame timing errors and is simple to implement.

[0091] According to one aspect of this application, the first signaling indicates a first system frame and a first Coordinated Universal Time (UTC), and the transmission timing of the first reference signal depends on the first system frame and the first UTC.

[0092] The above method uses the first system frame and the first world coordination time to determine the transmission timing of the first reference signal, which helps to improve the accuracy of the transmission timing of the first reference signal and further improve the accuracy of the transmission time of the first node's position or the first physical layer information.

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 3 shows the radio protocol architecture for the control plane 300 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 herein as PHY 301. Layer 2 (L2 layer) 305 is above PHY 301 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.

[0698] Example 4

[0699] Embodiment 4 illustrates a schematic diagram of a first communication device and a second communication device according to this application, as shown in Figure 4. Figure 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.

[0700] The first communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmitting processor 468, a receiving processor 456, a multi-antenna transmitting processor 457, a multi-antenna receiving processor 458, a transmitter / receiver 454, and an antenna 452.

[0701] The second communication device 410 includes a controller / processor 475, a memory 476, a receiver processor 470, a transmitter processor 416, a multi-antenna receiver processor 472, a multi-antenna transmitter processor 471, a transmitter / receiver 418, and an antenna 420.

[0702] In the 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 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 retransmitting 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). Transmit processor 416 performs encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 410, and mapping of signal clusters based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), M-Phase Shift Keying (M-PSK), M-QAM). Multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based and non-codebook-based precoding, and beamforming processing, generating one or more spatial streams. Transmit processor 416 then maps each spatial stream to subcarriers, multiplexes it with a reference signal (e.g., a pilot) in the time and / or frequency domains, and subsequently uses inverse fast Fourier transform (IFFT) to generate a physical channel carrying the time-domain multicarrier symbol stream. Multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multicarrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multi-antenna transmitter processor 471 into an radio frequency stream, which is then provided to different antennas 420.

[0703] 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 a signal through 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 multicarrier symbol stream, which is then provided to the receiver processor 456. The receiver processor 456 and the multi-antenna receiver processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiver processor 458 performs receive analog precoding / beamforming operations on the baseband multicarrier symbol stream from the receiver 454. The receiver processor 456 uses a Fast Fourier Transform (FFT) to convert the baseband multicarrier 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 receiver processor 456, where the reference signal is used for channel estimation, and the data signal is recovered in the multi-antenna receiver processor 458 after multi-antenna detection to recover any spatial stream destined for the first communication device 450. Symbols on each spatial stream are demodulated and recovered in the receive processor 456, generating soft decisions. The receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper-layer data and control signals transmitted by the second communication device 410 over the physical channel. The upper-layer data and control signals are then provided to the controller / processor 459. The controller / processor 459 implements the functions of Layer 2. The controller / processor 459 may be associated with a memory 460 storing program code and data. The memory 460 may be referred to as computer-readable media. In the transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transport and logical channels to recover upper-layer data packets from the core network. The upper-layer data packets are then provided to all protocol layers above Layer 2. Various control signals may also be provided to Layer 3 for Layer 3 processing.

[0704] 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 the controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission functions 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, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocation, implementing L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for retransmitting lost packets and signaling to the second communication device 410. Transmit processor 468 performs modulation mapping and channel coding processing, while multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming processing. Subsequently, transmit processor 468 modulates the generated spatial stream into a multi-carrier / single-carrier symbol stream. After analog precoding / beamforming operations in multi-antenna transmit processor 457, the stream is provided to different antennas 452 via transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by multi-antenna transmit processor 457 into a radio frequency symbol stream before providing it to antenna 452.

[0705] In the transmission from the first communication device 450 to the second communication device 410, the function at the second communication device 410 is similar to the receiving function 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 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 receiving processor 472 and the receiving processor 470. The receiving processor 470 and the multi-antenna receiving 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 computer-readable media. In the transmission from the first communication device 450 to the second communication device 410, the controller / processor 475 provides multiplexing between the transmission and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper-layer data packets from the UE 450. Upper-layer packets from the controller / processor 475 can be provided to the core network.
