[0238] Example 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture for the user plane and control plane according to an embodiment of this application, as shown in Figure 3.

[0239] Example 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture for a user plane and control plane according to this application, as shown in Figure 3. 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 between a first communication node device (UE, gNB, or RSU in V2X) and a second communication node device (gNB, UE, or RSU in V2X), or between two UEs, 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. Layer 1 will be referred to herein as PHY 301. Layer 2 (L2 layer) 305 is above PHY 301 and is responsible for the link between the first communication node device and the second communication node device, or between two UEs. Layer L2 305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the second communication node device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. It also provides security through encrypted data packets and supports cross-cell mobility between the second communication node devices and the first communication node device. The RLC sublayer 303 provides upper-layer packet segmentation and reassembly, retransmission of lost packets, and packet reordering to compensate for out-of-order reception due to HARQ. The MAC sublayer 302 provides multiplexing between logical and transport channels. It is also responsible for allocating various radio resources (e.g., resource blocks) within a cell among the first communication node devices. Furthermore, the MAC sublayer 302 handles HARQ operations. In the control plane 300, the Radio Resource Control (RRC) sublayer 306 of Layer 3 (L3) is responsible for acquiring radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between the second and first communication node devices. The user plane 350's radio protocol architecture includes Layer 1 (L1) and Layer 2 (L2). The radio protocol architecture for the first and second communication node devices in the user plane 350 is largely the same as the corresponding layers and sublayers in the control plane 300 for Physical Layer 351, PDCP sublayer 354 in L2 Layer 355, RLC sublayer 353 in L2 Layer 355, and MAC sublayer 352 in L2 Layer 355.

[0247] Example 4

[0248] Example 4 illustrates a schematic diagram of a first communication device and a second communication device according to an embodiment of this application, as shown in Figure 4. Figure 4 is a block diagram of a first communication device 410 and a second communication device 450 communicating with each other in an access network.

[0249] The first 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.

[0250] The second 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.

[0251] In the transmission from the first communication device 410 to the second communication device 450, at the first 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 DL (Downlink), the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the second communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for HARQ operation, retransmission of lost packets, and signaling to the second communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for L1 layer (i.e., physical layer). Transmit processor 416 performs encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 450, and constellation mapping based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-phase shift keying (M-PSK), and M-quadrature amplitude modulation (M-QAM). 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, generating one or more parallel... The transmit processor 416 then maps each parallel stream to a subcarrier, multiplexes the modulated symbols with a reference signal (e.g., a pilot) in the time and / or frequency domains, and then uses an inverse fast Fourier transform (IFFT) to generate a physical channel carrying the time-domain multicarrier symbol stream. The 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 transmit processor 471 into an RF stream, which is then provided to a different antenna 420.

[0252] In the transmission from the first communication device 410 to the second communication device 450, at the second 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 parallel stream destined for the second communication device 450. Symbols on each parallel 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 over the physical channel by the first communication device 410. 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 (L2). 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 DL (Layered Logic), the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transmission and logical channels to recover upper-layer packets from the core network. The upper-layer packets are then provided to all protocol layers above Layer 2. Various control signals may also be provided to Layer 3 (L3) for L3 processing. The controller / processor 459 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0253] In the transmission from the second communication device 450 to the first communication device 410, at the second 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 first communication device 410 described in the DL, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on the radio resource allocation of the first communication device 410, implementing L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the first 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 parallel 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.

[0254] In the transmission from the second communication device 450 to the first communication device 410, the function at the first communication device 410 is similar to the receiving function at the second communication device 450 described in the transmission from the first communication device 410 to the second 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. The controller / processor 475 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transmission and logical channels to recover upper-layer data packets from the second communication device 450. The upper-layer data packets from the controller / processor 475 may be provided to the core network. The controller / processor 475 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0525] Example 11

[0526] Example 11 illustrates a schematic diagram of conflict handling for processing resources according to an embodiment of this application; as shown in Figure 11.

[0527] In Example 11, the first wireless channel is one of two wireless channels, and the total processing resources required for the processing of the two wireless channels based on AI exceed the available processing resources; wherein,

[0528] The processing of the other wireless channel, which is different from the first wireless channel, is abandoned;

[0529] or,

[0538] As an example, the reference wireless channel is another wireless channel besides the first wireless channel of the two wireless channels; the processing of the reference channel not based on AI includes: the processing of the reference channel does not employ an AI model.

[0539] As an example, the reference wireless channel is another wireless channel besides the first wireless channel of the two wireless channels; the processing of the reference channel not based on AI includes: the processing of the reference channel is based on conventional non-AI methods.

[0540] As an example, the reference channel is an uplink channel, and the processing of the reference channel is based on traditional non-AI methods, such as the generation methods of PUSCH and PUCCH in protocols prior to 3GPP R19.

[0541] As an example, the reference channel is a downlink channel, and the processing of the reference channel is based on traditional non-AI methods. It can refer to the processing methods of PDSCH and PDCCH in protocols prior to 3GPP R19. The specific processing algorithm is related to the implementation of the first node, that is, it is determined by the hardware equipment vendor of the first node. However, those skilled in the art know that, in terms of effect, the processing method of the first node can usually be considered as the inverse operation of the generation method of the transmitting end.

[0542] As an example, available processing resources refer to processing resources other than the already occupied processing resources among all processing resources of the first node.

[0551] Example 12

[0552] Example 12 illustrates a schematic diagram of conflict handling for processing resources according to another embodiment of this application; as shown in Figure 12.

[0553] In Example 12, the processing resources required by the first node for processing the first wireless channel and generating the first channel information based on AI exceed the available processing resources; wherein,

[0554] The first node abandons transmitting the first channel information;

[0555] or,

[0556] The first node sends the first channel information that is not generated based on AI.

[0557] Figure 12 illustrates the two implementation methods described above, as shown in (a) and (b) respectively; in (a), the first node abandons the generation and transmission of the first channel information; in (b), the first node changes the generation method of the first channel information to be non-AI-based.

[0558] As one embodiment, the first node abandoning the transmission of the first channel information includes: the first node abandoning the generation of the first channel information.

[0559] As an example, for the first channel information not generated based on AI, the CSI generation method in protocols prior to 3GPP R19 can be referenced.

[0560] As an example, the specific algorithm for generating the first channel information not based on AI is implementation-dependent for the first node, i.e., determined by the hardware vendor of the first node. A typical but non-limiting implementation is described below:

[0561] In one implementation, the first channel information includes L1-RSRP or L1-SINR; the first node obtains L1-RSRP or L1-SINR based on the measurement of RS resources. Generally speaking, the filtering algorithm of L1-RSRP or L1-SINR is determined by the manufacturer of the first node, or is implementation-related, and can be implemented by an algorithm or by hardware.

[0562] In another implementation, the first node performs channel measurements on the RS resources to obtain the channel parameter matrix H. r×P For the channel parameter matrix H r×P Power adjustment is performed, and the adjusted channel parameter matrix is ​​as follows: Where Q is the ratio of the assumed PDSCH (Physical Downlink Shared Channel) EPRE (Energy Per Resource Element) to the NZP CSI-RS EPRE. When using the precoding matrix W... P×l Under these conditions, the precoded channel parameter matrix is: W P×l Where l is the rank or the number of layers. In one case, l is a positive integer not greater than P; in another case, the precoding matrix is ​​an identity matrix, in which case P = l. H is calculated using criteria such as SINR (Signal Interference Noise Ratio), EESM (Exponential Effective SINR Mapping), or RBIR (Received Block Mean Mutual Information Ratio). r×P ·W P×lThe equivalent channel capacity is calculated, and then the first channel information is reported using methods such as table lookup based on the equivalent channel capacity. Generally, the calculation of the equivalent channel capacity requires the first node to estimate interference (including noise). Typically, the mapping from the equivalent channel capacity to CSI depends on receiver performance or hardware-related factors such as modulation scheme.

[0566] Typically, the first type of processing resources differs from the second type of processing resources.

[0567] As an example, the first type of processing resources and the second type of processing resources are processing resources with different names.

[0568] As one example, the first type of processing resources and the second type of processing resources are used for different functions.

[0569] As an example, the first type of processing resources is suitable for processing wireless channels, and the second type of processing resources is suitable for generating channel information.

[0570] As an example, the first type of processing resources and the second type of processing resources have different names.

[0585] As an example, any one of the L+1 sequentially arranged data blocks includes at least one service data, which is a complex number or a vector; the output W of the first decoder i It is a data block.

[0586] In the above embodiments, the input and output of the first encoder are data blocks and bit blocks, respectively, and the input and output of the first decoder are bit blocks and data blocks, respectively; therefore, the training dataset used to train the AI ​​model is also a data block.

[0587] As a sub-implementation of the above embodiment, the CRC check applies a CRC bit block of a reference bit block, which is obtained by quantizing the first data block.

[0588] In Example 14B, the output of the first encoder at time #i is V. i The first encoder's input at time #i is data block #i, and L past encoded outputs V. i-1 V i-2 , ..., V i-L (where the subscript represents time); the input of the first decoder includes the V i And L past decoded outputs W i-1 W i-2 ,…,W i-L .
