Description

A method and apparatus for reporting transmission modes in nodes used in wireless communication. Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to schemes and apparatus for reporting transmission modes in wireless communication systems. Background Technology

[0002] In traditional wireless communication, channel coding is used to improve the reliability of wireless communication. Typical channel coding techniques include Turbo codes, LDPC (Low Density Parity Check Code), polar codes, etc. In traditional wireless communication, the UE (User Equipment) calculates and reports CSI (Channel State Information) by measuring reference signals. The CSI includes, but is not limited to, one or more of CRI (Channel State Information-Reference Signal Resource Indicator), RI (Rank Indicator), PMI (Precoding Matrix Indicator), or CQI (Channel Quality Indicator). The CQI indicates the transmission mode, including the modulation scheme and code rate, and the efficiency of the transmission mode is equal to the product of the modulation scheme and the code rate.

[0003] With the popularization of AI (Artificial Intelligence) or ML (Machine Learning) technologies, AI / ML-based encoding and decoding technologies have become a research hotspot in 6G communications, such as joint coding techniques for sources and channels, and cross-layer coding techniques. Since the specifications of AI models may exceed the scope of 3GPP (except for the reference model used for performance calibration), the specific implementation methods for AI / ML training and inference may be determined by the hardware equipment manufacturers themselves. These can be based on classic models such as Transformer structures, RNNs (Recurrent Neural Networks), and CNNs (Conventional Neural Networks), or hybrid models composed of multiple models. Summary of the Invention

[0004] The applicant's research revealed that the key issue that needs to be addressed is how to select a transmission method to better adapt to new encoding technologies.

[0005] In view of the above problems, this application discloses a solution. It should be noted that although the motivation for this application stems from AI / ML-based encoding techniques, it is also applicable to traditional non-AI / ML encoding techniques, and techniques combining AI / ML-based encoding with traditional non-AI / ML encoding. This is especially true considering that specific encoder / decoder algorithms are likely non-standardized or implemented by hardware manufacturers themselves. Furthermore, adopting a unified solution can reduce implementation complexity or cost, or improve performance. Unless otherwise specified, the embodiments and features in the first node of this application can be applied to the second node. Unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0006] Where necessary, the interpretation of terms used in this application may be referenced to the descriptions in the TS38 series of specification protocols of the 3GPP (3rd Generation Partner Project).

[0230] Example 3

[0231] 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.

[0232] 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.

[0240] Example 4

[0241] 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.

[0242] 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.

[0243] 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.

[0244] 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.

[0245] 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.

[0246] 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.

[0247] 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.

[0472] As one example, the auxiliary bit block includes one or more bits.

[0473] As an example, the at least one auxiliary bit block is assumed by the first node.

[0474] As an example, the at least one auxiliary bit block is indicated to the first node by the second node or the receiver of the at least first control information.

[0486] Example 7

[0487] Example 7 illustrates a schematic diagram of the transmission method of a first control information indication according to an embodiment of the present application; as shown in Figure 7.

[0488] In embodiment 7, the transmission mode indicated by the first control information satisfies the following condition: when a first encoder is used, a first bit block using the transmission mode indicated by the first control information is received with a block error rate not exceeding a first threshold, where the first threshold is a positive real number greater than 0 and less than 1.

[0489] As an example, the transmission mode indicated by the first control information is one of M transmission modes, where M is a positive integer greater than 1; any of the M transmission modes satisfies the following: under the condition of using the first encoder, the first bit block using the transmission mode is received with a block error rate not exceeding the first threshold, where the first threshold is a positive real number greater than 0 and less than 1.

[0490] As an example, the transmission mode indicated by the first control information is conditional upon the use of a first encoder.

[0491] As an example, the block error rate is BLER (Block Error Rate).

[0492] As an example, the block error rate is the probability of a bit block error.

[0493] As an example, the block error rate is the probability of a transport block error.

[0494] As an example, the first threshold is 0.1.

[0495] As an example, the first threshold is 0.01.

[0496] As an example, the first threshold is 0.00001.

[0497] As an example, determining whether "the first bit block using the transmission method is received with a block error rate not exceeding a first threshold" is determined by the manufacturer of the first node, or is implementation-related. A typical but non-limiting implementation is described below:

[0498] The first node obtains the SINR value based on the measurement on at least the first RS resource described in this application. It determines whether "the first bit block using the transmission method is received at a block error rate not exceeding the first threshold" based on whether the block error rate mapped to the SINR value on the "SINR and block error rate relationship curve" of the transmission method exceeds the first threshold. It is determined that "the first bit block using the transmission method is received at a block error rate not exceeding the first threshold" only if the mapped block error rate does not exceed the first threshold.

[0499] The SINR and block error rate relationship curve can be for an AI-based encoder, or for the first encoder (i.e., different encoders may correspond to different "SINR and block error rate relationship curves"), or for the first bit block (i.e., different bit blocks may correspond to different "SINR and block error rate relationship curves").

[0500] Example 8

Any of the M CQI indices satisfies the following condition: under the condition of using the first encoder, the first bit block using the transmission mode indicated by the CQI index on the CSI reference resource is received with a block error rate not exceeding a first threshold.

[0508] In the above method, the larger the index, the more efficient the transmission method it indicates.

[0509] As an example, the M indices respectively indicate the M transmission methods, and the larger the index, the more efficient the transmission method indicated; the transmission method indicated by the first control information is the most efficient among the M transmission methods means that the transmission method indicated by the first control information is the transmission method indicated by the largest index among the M indices.

[0510] As an example, the index indicating the transmission method is the CQI index.

[0511] As an example, the index indicating the transmission method is a non-negative integer.

[0512] In the above method, the calculation method for the efficiency of the transmission mode is similar to that in 3GPP TS 38.214, exhibiting good standard compatibility and simple design. A higher efficiency of the transmission mode indicates a greater number of information bits transmitted per second under that mode. The above method selects the most efficient transmission mode, thereby improving the system's transmission efficiency.

The reference encoder is either the first encoder in this application or one of the N encoders.

[0718] Generally speaking, how the first node utilizes the output V of the reference encoder... i The method for recovering the reference data block is implementation-dependent, meaning it is determined by the hardware vendor of the first node; the reference decoder in Embodiment 15A is merely one non-limiting implementation. As shown in Figure 15A, the input of the reference decoder includes the V iAnd L data blocks arranged in sequence, namely data block #1, data block #2, ..., data block #L.

[0721] In the above embodiments, the input and output of the reference encoder are both bit blocks, and the input and output of the reference decoder are both bit blocks; therefore, the training dataset used to train the AI ​​model is also a quantized bit block.

[0722] As a sub-implementation of the above embodiment, the CRC check applies the CRC bit block of the reference data block.

[0723] 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 reference decoder i It is a data block.

[0724] In the above embodiments, the input and output of the reference encoder are data blocks and bit blocks, respectively, and the input and output of the reference decoder are bit blocks and data blocks, respectively; therefore, the training dataset used to train the AI ​​model is also a data block.

[0725] 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 reference data block.

[0726] In Example 15B, the output of the reference encoder at time #i is V. i The reference 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 reference decoder includes the V i And L past decoded outputs W i-1 W i-2 ,…,W i-L .

[0727] The delay shown in Figure 15B is merely an exemplary implementation and can be replaced by other operations, such as an RNN model or a linear algorithm such as a sliding filter.

[0728] The reference encoder and the reference decoder can employ various AI models such as transformers and CNNs, which are determined by the hardware vendor.

[0729] The embodiments concerning check bits or service data involved in Embodiment 15A are still applicable to Embodiment 15B, and will not be repeated here.

[0732] As an example, P1 is two, meaning the P1 encoding layers include encoding layer #1 and encoding layer #2, where encoding layer #1 is a convolutional layer and encoding layer #2 is a fully connected layer. In the convolutional layer, at least one convolutional kernel is used to convolve the input of the reference encoder to generate a corresponding feature map. At least one feature map output from the convolutional layer is reshaped into a vector and input to the fully connected layer. The fully connected layer transforms the vector into the output of the reference encoder.
