Description

Technical Field

[0001] This application relates to methods and apparatus in wireless communication systems, and more particularly to schemes and apparatus for AI (Artificial Intelligence) or ML (Machine Learning) in wireless communication systems. Background Technology

[0002] To assist terminals in channel estimation, frequency offset error estimation, and signal synchronization, 3GPP (the 3rd Generation Partnership Project) defines quasi-colocation (QCL) for New Radio (NR). This means that if the channel parameters experienced by an antenna port of one Reference Signal (RS) resource can be used to infer the channel parameters experienced by an antenna port of another RS ​​resource, then the two antenna ports are quasi-colocated. Common channel parameters on antenna ports include Doppler spread, Doppler shift, average delay, delay spread, average gain, and spatial receiver parameters.

[0003] In NR R (release) 18, projects based on AI (Artificial Intelligence) or ML (Machine Learning) for the NR air interface were approved, including:

[0004] - Beam management, which includes prediction of downlink transmission beams for both the UE-side model and the network-side model;

[0005] - Enhanced CSI (Channel State Information) feedback, including CSI compression in the two-sided model and CSI prediction in the UE-side model;

[0006] - Enhanced positioning accuracy, including direct AI / ML positioning and AI / ML-assisted positioning.

[0007] Since the specifications of AI models may extend beyond the scope of 3GPP (besides the reference model 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. Summary of the Invention

[0008] The inventors discovered through research that the existing methods for acquiring channel parameters experienced by the antenna port of RS resources are inefficient. In particular, when the state of the RRC (Radio Resource Control) connection changes, such as RRC connection re-establishment, RRC connection establishment, and RRC connection resumption, the UE has difficulty acquiring the channel parameters experienced by the antenna port of the RS resource in a timely manner. With 3GPP's continuous exploration of AI / ML, how to acquire the channel parameters experienced by the antenna port of an RS resource when the state of the RRC connection changes is a problem that needs to be solved.

[0009] In view of the above problems, this application discloses a solution. It should be noted that although the motivation for this application stems from the scenario of RRC connection state changes, it is also applicable to the scenario of primary cell group configuration. It should also be noted that although the motivation for this application stems from the scenario of AI / ML, it is also applicable to non-AI / ML scenarios. Unless otherwise specified, the embodiments and features in any node of this application can be applied to any other node. Unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0010] Where necessary, the interpretation of terms used in this application may be referenced to the descriptions in the TS38 series of specification protocols of 3GPP (3rd Generation Partner Project).

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

[0012] Receive a first RRC signaling, wherein the first RRC signaling configures a first RS resource; perform measurements on the first RS (Reference Signal) resource; receive a second RRC signaling, wherein the second RRC signaling configures a second RS resource; perform measurements on the second RS resource;

[0013] Wherein, the channel parameters experienced by an antenna port of the first RS resource are used to infer the channel parameters experienced by an antenna port of the second RS resource, and the channel parameters experienced by the antenna port of the second RS resource depend on the measurement on the second RS resource; the first RRC signaling precedes the second RRC signaling; the second RRC signaling is used to configure the primary cell group, or the second RRC signaling is used to establish an RRC connection, or the second RRC signaling is used to re-establish an RRC connection, or the second RRC signaling is used to restore an RRC connection.

[0014] In existing technologies, when a UE leaves the RRC_CONNECTED state (e.g., enters the RRC_IDLE or RRC_INACTIVE state) or experiences an RLF (Restricted Link Failure), the UE releases the configuration information of the RS (Restricted Support Resource) resources. After receiving signaling used to change the state of the RRC connection, the UE struggles to promptly obtain the channel parameters experienced by the antenna port of the RS resource, hindering transmission. The aforementioned method infers the channel parameters experienced by one antenna port of the second RS resource from the channel parameters experienced by one antenna port of the first RS resource, solving this problem and facilitating timely acquisition of the channel parameters experienced by the antenna port of an RS resource.

[0015] Considering the uncertainty in the relationship between RS resources due to channel variations, in the above method, the channel parameters experienced by the antenna port of the second RS resource depend on the measurement on the second RS resource, which helps to improve the accuracy of inferring the channel parameters experienced by the antenna port of an RS resource.

[0016] Considering that in the existing technology, the network needs to rely on the measurement information reported by the UE on the RS resource to configure the channel parameters for the UE, the above method infers the channel parameters experienced by the antenna port of the current RS resource by using the channel parameters experienced by the antenna port of the previous RS resource, thereby avoiding or reducing the reporting and helping to reduce traditional signaling overhead.

[0017] As one embodiment, the second RRC signaling is used to configure the primary cell group, and the second RRC signaling is used to establish an RRC connection.

[0018] As one embodiment, the second RRC signaling is used to configure the primary cell group, and the second RRC signaling is used to rebuild the RRC connection.

[0019] As one embodiment, the second RRC signaling is used to configure the primary cell group, and the second RRC signaling is used to restore the RRC connection.

[0020] According to one aspect of this application, the first RS resource and the second RS resource are both on a first cell; the second RRC signaling includes a serving cell configuration for the first cell.

[0022] Send the first report;

[0023] The first reporting information is configured by the second RRC signaling, and the first reporting information depends on the channel parameters experienced by the antenna port of the second RS resource.

[0025] According to one aspect of this application, the channel parameters experienced by the one antenna port of the second RS resource are obtained through inference; the second RRC signaling is used to indicate a first parameter set, which is used for the inference of the channel parameters experienced by the one antenna port of the second RS resource.

[0026] The above method, based on the first set of network configuration parameters, infers the channel parameters experienced by the antenna port of the second RS resource, which helps to improve the reliability of the obtained channel parameters.

[0027] According to one aspect of this application, the second RRC signaling includes a first identifier, which is used to determine that the channel parameters experienced by the one antenna port of the first RS resource are used to infer the channel parameters experienced by the one antenna port of the second RS resource.

[0030] Send the first auxiliary message;

[0031] The channel parameters experienced by the antenna port of the first RS resource are used to infer that the channel parameters experienced by the antenna port of the second RS resource depend on the first auxiliary information.

[0032] The above method is beneficial for providing auxiliary information to the network; in addition, if the first node does not send the first auxiliary information, the channel parameters experienced by an antenna port of the first RS resource can be excluded from inferring that the channel parameters experienced by an antenna port of the second RS resource depend on the first auxiliary information, thereby achieving differentiated UE configuration.

[0033] According to one aspect of this application, it is characterized by comprising:

[0034] After the first auxiliary information is sent, the third RRC signaling is received;

[0035] The third RRC signaling is used to determine the channel parameters experienced by the antenna port of the first RS resource, which is then used to infer the channel parameters experienced by the antenna port of the second RS resource.

[0036] The above methods are beneficial for improving the scheduling decision-making performance of the network.

[0037] According to one aspect of this application, when the second RRC signaling is received, the channel parameters experienced by the antenna port of the first RS resource are stored.

[0038] The above method avoids the channel parameters experienced by the antenna port of the first RS resource.

[0300] Example 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture for a user plane and a control plane according to this application, as shown in the attached diagram. Figure 3 As shown. Figure 3 This is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and the control plane 300. Figure 3The radio protocol architecture for control plane 300 is illustrated using 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. L1 layer will be referred to as PHY301 in this document. Layer 2 (L2 layer) 305 sits above PHY301 and includes the MAC (Medium Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the PDCP (Packet Data Convergence Protocol) sublayer 304. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. It also provides security through encrypted data packets and cross-area mobility support. The RLC sublayer 303 provides segmentation and reassembly of upper-layer packets, retransmission of lost packets, and packet reordering to compensate for out-of-order reception due to HARQ (Hybrid Automatic Repeat Request). MAC sublayer 302 provides multiplexing between the logical and transport channels. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell.

[0316] Example 4

[0317] Example 4 shows schematic diagrams 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 This is a block diagram of a first communication device 450 and a second communication device 410 communicating with each other in the access network.

[0318] 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.

[0319] 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.

[0320] 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.

[0321] 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.

[0322] 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.

[0323] 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.

[0792] Example 17

[0793] Example 17 illustrates a schematic diagram of intelligent function deployment in a RAN (Radio Access Network) domain according to an embodiment of this application; as shown in the appendix. Figure 17 As shown. In Example 17, the gNB can be replaced with, for example, an eNB, or a network device such as a 6G base station.

[0794] Intelligent functions in the RAN domain include training (also known as ML training, AI training, or AI / ML training), testing (also known as ML testing, AI testing, or AI / ML testing), and inference (also known as ML inference, AI inference, or AI / ML inference), among others. Training, testing, and inference functions can be deployed independently or co-located. Deployment of intelligent functions can be achieved through software, such as downloading and / or running executable files; or through a combination of software and hardware, such as accelerating specific computing units through hardware to improve processing speed or save power.

[0795] Training functions can be deployed in a cross-domain management system or a domain-specific management system; the domain-specific management system is used to manage the RAN domain or the CN (Core Network) domain. For example, training functions for MDA (Management Data Analytics) can be deployed in MDAF (MDA Function); training functions for network data analytics can be deployed in NWDAF (Network Data Analytics Function), meaning the training function is MTLF (Model Training Logical Function).

[0796] Similarly, inference functions can be deployed in cross-domain management systems or domain-specific management systems; for example, the inference function is an MDAF, or the inference function is an AnLF (Analytics logical function) located in an NWDAF.

[0797] Similarly, testing functionality can also be deployed in cross-domain management systems or domain-specific management systems.

[0798] In embodiment 17, the training function 1702 of the RAN domain is located in the management function 1703 of the RAN domain; while the inference function is located in the base station, that is, inference function 1704 is located in gNB 1705, and inference function 1706 is located in gNB 1707. Figure 17 The ellipsis in the text indicates other gNBs that include other reasoning functions and are not shown.

[0799] Appendix Figure 17 In this context, the management of inference functions for multiple base stations is handled by the RAN domain management function 1703, which interacts with the RAN domain MnS (Management Service) consumer / cross-domain management 1701 (as shown in the attached diagram). Figure 17 (As shown by the dashed arrow 1708 in the image).

[0800] Optionally, the management of inference functions can also be completed by the base station itself, that is, each base station can independently interact with the RAN domain MnS consumer / cross-domain management 1701.

[0801] It should be noted that Embodiment 17 is merely a non-limiting implementation; optionally, the RAN domain training function may also be deployed at the base station; or optionally, some base stations may deploy both inference function and RAN domain training function, while some base stations may only deploy inference function.

[0814] The UE intelligent function 1804 is deployed in the first node of this application. The UE intelligent function 1804 includes an inference function 1806.
