[0071] The technical solution of this application will be further described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0072] Example 1

[0073] Example 1 illustrates a flowchart of communication of a first node according to an embodiment of this application, as shown in the attached diagram. Figure 1 As shown.

[0074] The first node 100 transmits an uplink signal at the target power in step 101.

[0075] In Example 1, the target power is the minimum of at least a first power, a second power, and a third power. The first power is the configured maximum power. The second power depends on path loss, closed-loop power control, and a first value. The third power depends on the first value and a value determined by the first node itself. The first value depends on the configuration.

[0076] As one example, the uplink signal carries user data or uplink control information.

[0077] As an example, the uplink signal is a signal transmitted in the uplink channel.

[0078] As an example, the uplink channel is PUSCH (Physical Uplink Shared Channel) or PUCCH (Physical Uplink Control Channel).

[0079] As an example, the uplink signal is an SRS (Sounding Reference Signal).

[0080] As an example, the uplink signal is PRACH (Physical Random Access Channel).

[0081] As an example, the uplink signal may be a signal defined in a 6G system.

[0082] As an example, in this application, the target power can be measured in dBm (milliwatts decibels).

[0083] As an example, in this application, the first power, the second power, and the third power can all be measured in dBm.

[0084] As an example, the first node determines the target power.

[0085] As an example, the target power is the transmission power of the uplink signal.

[0086] As an example, the target power is the minimum of the first power, the second power, and the third power.

[0087] As an example, the target power is the smallest of a plurality of powers; the plurality of powers includes the first power, the second power, and the third power, and also includes at least one power other than the above three.

[0088] As an example, the magnitude of a power other than the first power, the second power, and the third power is configured.

[0089] As an example, a power other than the first power, the second power, and the third power can be determined according to an agreement between the communicating parties.

[0090] As one embodiment, a power other than the first power, the second power, and the third power can also be determined in the manner mentioned above, or in other ways; generally speaking, the advantages of the solution disclosed in this application are not limited to the method of determining this power.

[0091] As an example, the multiple power values ​​can all be measured in dBm.

[0092] As an example, the maximum power of the configuration is defined for the carrier used to transmit the uplink signal.

[0093] As an example, the maximum power of the configuration is relative to the transmission opportunity used to transmit the uplink signal.

[0094] As an example, the uplink signal is transmitted in the PUSCH, and the transmission opportunity for transmitting the uplink signal is a PUSCH transmission occasion.

[0095] As an example, the uplink signal is transmitted in the PUCCH, and the transmission opportunity for transmitting the uplink signal is a PUCCH transmission occasion.

[0096] As an example, the uplink signal is an SRS, and the transmission opportunity for transmitting the uplink signal is an SRS transmission occasion.

[0097] As an example, the maximum power of the configuration is the maximum output power of the configuration.

[0098] As an example, the maximum power of the configuration is the maximum allowed transmission power.

[0099] As an example, the maximum power configured is that of the first node.

[0100] As an example, the second power (measured in dBm) is equal to the sum of at least three values ​​(measured in dB or dBm), one of which depends on path loss, another of which depends on closed-loop power control, and the at least three values ​​also include the first value.

[0101] As one embodiment, the second power depends on path loss, closed-loop power control, and a first value, including: the second power and the first value have a linear relationship.

[0102] As one embodiment, the second power depends on path loss, closed-loop power control, and a first value, including: the second power and the path loss estimate have a linear relationship.

[0103] As one embodiment, the second power depends on path loss, closed-loop power control, and the first value, including: the second power and the power adjustment amount of the closed-loop power control have a linear relationship.

[0104] As an example, the first value is indicated by configuration parameters.

[0105] As an example, the configuration parameters can be physical layer parameters or higher layer parameters.

[0106] As an example, the configuration parameters can be sent from the second node in this application to the first node.

[0107] As an example, the first value is calculated based on the configuration information.

[0108] As an example, the first value is calculated based on the time-frequency resources allocated to the uplink signal.

[0109] As one embodiment, the third power depends on the first value and a value determined by the first node itself, including: the third power and the first value have a linear relationship.

[0110] As one embodiment, the third power depends on the first value and a value determined by the first node itself, including: the third power and a value determined by the first node are linearly related.

[0111] As an example, the power calculation in this application is performed using dBm as the unit of measurement. Equivalent calculation methods (e.g., converting to linear power values ​​for calculation, using mW or W as the unit of measurement) are obviously also within the scope of protection of this application.

[0112] Example 2

[0113] Example 2 illustrates a schematic diagram of a network architecture according to an embodiment of this application, as shown in the attached diagram. Figure 2 As shown. (Attached) Figure 2The system architectures of 5G NR (New Radio), LTE (Long-Term Evolution), and LTE-A (Long-Term Evolution Advanced) are described. The 5G NR or LTE network architecture 200 can be referred to as 5GS (5G System) / EPS (Evolved Packet System) or some other suitable term.

The MME / AMF / UPF 211 is the control node that handles signaling between the UE 201 and the EPC / 5G-CN 210. Generally, the MME / AMF / UPF 211 provides bearer and connection management. All user IP (Internet Protocol) packets are transmitted through the S-GW 212, which is itself connected to the P-GW 213. The P-GW 213 provides UE IP address allocation and other functions. The P-GW 213 is connected to Internet Service 230. Internet services 230 include operator-compliant Internet protocol services, which may specifically include the Internet, intranets, IMS (IP Multimedia Subsystem), and packet-switched streaming services.

[0114] It should be noted that the above embodiment 2 is a non-limiting implementation method; the solution disclosed in this application is also applicable to other network architectures, such as the network architecture of 6G systems.

[0125] Example 3

[0126] 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 the control plane 300 between user node equipment (UE or RSU in V2X, onboard equipment or onboard communication module) and network node equipment (gNB, UE or RSU in V2X, onboard equipment or onboard communication module), or between two UEs, 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 is responsible for the links between the user node equipment and network node equipment, as well as between two UEs, through PHY301. L2 layer 305 includes the MAC (Medium Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the network node equipment. PDCP sublayer 304 provides data encryption and integrity protection, and also supports cross-cell mobility between user node devices and network node devices. RLC sublayer 303 provides packet segmentation and reassembly, implements retransmission of lost packets through ARQ, and also provides duplicate packet detection and protocol error detection. MAC sublayer 302 provides mapping between logical and transport channels and multiplexing of logical channels. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell among user node devices. MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3) of the control plane 300 is responsible for acquiring radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between network node devices and user node devices. The radio protocol architecture of user plane 350 includes Layer 1 (L1 layer) and Layer 2 (L2 layer). The radio protocol architecture for user node devices and network node devices in user plane 350 is largely the same as the corresponding layers and sublayers in 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. However, PDCP sublayer 354 also provides header compression for upper layer packets to reduce radio transmission overhead. L2 layer 355 in user plane 350 also includes SDAP (Service Data Adaptation Protocol) sublayer 356. SDAP sublayer 356 is responsible for mapping between QoS streams and Data Radio Bearers (DRBs) to support service diversity.Although not illustrated, the user node device may have several upper layers above the L2 layer 355, including a network layer (e.g., IP layer) terminating at the P-GW on the network side and an application layer terminating at the other end of the connection (e.g., remote UE, server, etc.).

[0132] As an example, the first UE capability information in this application is generated in the MAC sublayer 302.

[0133] As an example, the first UE capability information in this application is generated in the RRC sublayer 306.

[0134] As an example, the higher layer mentioned in this application refers to the layer above the physical layer.

[0135] Example 4

[0136] Example 4 illustrates a hardware module schematic diagram of a communication node according to an embodiment of this application, as shown in the attached diagram. 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.

[0137] 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.

[0138] 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.

[0139] 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 channel coding 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.

[0140] 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 deinterleaves and decodes 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 second node 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.

[0141] 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 channel coding, interleaving, and modulation mapping. Multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming. Subsequently, transmit processor 468 modulates the generated spatial stream into a multi-carrier / single-carrier symbol stream.

[0327] As an example, the above method allows the first node to select the appropriate third power according to specific conditions, avoiding the introduction of unnecessary restrictions in the above selection, and is conducive to improving the accuracy of power control.

[0328] As an example, as a form equivalent to the target power being determined as the minimum of the first power, the second power, and the third power (where it can be assumed that the minimum value in the range corresponding to the second value is 0): the first node can determine the target power itself within the following range:

[0329] The sum of all values ​​other than the second value among the plurality of values ​​is less than or equal to the target power.

[0330] As an example, as a form equivalent to the target power being determined as the minimum of the first power, the second power, and the third power (where it can be assumed that the range corresponding to the second value is an open interval or a half-open interval with a lower bound of 0 but not including 0): the first node can determine the target power itself within the following range.

[0331] The sum of all values ​​other than the second value among the plurality of values ​​is less than the target power.

[0332] It should be noted that when the target power is determined according to the above two methods, it is not necessary to define the third power and the second value during the determination process (correspondingly, for the multiple values, only the part other than the second value needs to be defined). The third power and the second value mentioned above are only for explanation.

[0336] In Example 10, the target power is determined to be at least the first power, and the minimum of the second power and the third power depends on the reporting of the first UE capability information.

[0337] As one embodiment, the first node reports the first UE capability information, and the target power is determined to be at least the minimum of the first power, the second power, and the third power; or,

[0338] If the first node does not report the first UE capability information, the target power is determined to be the minimum of the first power and the second power.

[0339] As an example, the target power is determined to be at least the minimum of the first power, the second power, and the third power only if the first UE capability information is reported.

[0340] As an example, if the first UE capability information is not reported, the target power is determined to be the minimum of the first power and the second power.

[0341] As one embodiment, the first UE capability information includes indication information of the power control mode.

[0342] As one embodiment, the first UE capability information includes indication information of AI capabilities.

[0343] As an example, the first UE capability information indicates that the first node can use AI / ML functions in power control.

[0344] As an example, the first node reports the first UE capability information, which includes indication information for AI / ML functions;

[0345] The determination of the second value may or may not use AI / ML functions; whether to use AI / ML functions, or how to use AI / ML functions, do not need to be defined by the protocol and can be implemented by the hardware equipment manufacturer of the first node.

[0346] As an example, the features of the above method include: the target power is determined to be at least the minimum of the first power, the second power, and the third power. Such a determination method can be applied only to UEs with certain AI capabilities; such a feature is beneficial for comprehensively considering UE capabilities and power control flexibility.

[0347] As an example, generally speaking, compared to traditional UEs, UEs with AI / ML functions can extract more (which may not be obvious to traditional UEs) effective information for utilization. Therefore, determining the power control method based on the reporting of the indication information of AI / ML functions is a reasonable, effective and compatible solution. In addition, without loss of generality, when the introduction of other functions besides AI / ML functions can also achieve the effect of extracting more effective information for utilization, it is obvious that the power control method can also be determined based on the reporting of the indication information of the other functions.

[0348] Example 11

[0349] Example 11 illustrates a schematic diagram of an artificial intelligence processing system according to an embodiment of this application, as shown in the attached diagram. Figure 11 As shown. (Attached) Figure 11 In this context, an AI processing system includes a first processor, a second processor, a third processor, and a fourth processor.

[0350] In Example 11, the first processor sends a first dataset to the second processor, and the second processor uses the first dataset to train and generate a target first type parameter set. The target first type parameter set describes an AI model, and the first dataset is also called the training dataset.

[0351] The second processor sends the generated target first-class parameter set to the third processor, which uses the target first-class parameter set to perform inference on the second dataset to obtain a first-class output, and then sends the first-class output to the fourth processor; the second dataset is also referred to as the inference dataset.

[0352] As an example, the AI ​​processing system described above can be used to infer the second value.

[0353] As an example, the first node determines on its own how to train to generate the target first class parameter set.

[0354] As an example, the first node can determine for itself whether / how to use the aforementioned AI processing system in the process of determining the second value.

[0355] As an example, the first dataset may include channel measurement data.

[0356] As an example, the first dataset may include data in a format agreed upon by both communicating parties.

[0357] As an example, the second dataset may include channel measurement data.

[0358] As an example, the second dataset may include data in a format agreed upon by both communicating parties.

[0359] As one embodiment, the third processor sends a first type of feedback to the second processor, and the first type of feedback is used to trigger a recalculation or update of the target first type of parameter group.

[0360] As an example, the fourth processor sends a second type of feedback to the first processor, which is used to trigger the collection of the first dataset or the collection of the second dataset.

[0361] As one embodiment, the first processor is located on an application server or on a network device side.

[0362] As one embodiment, the second processor is located at the first node.

[0363] As one embodiment, the second processor is located on the application server or on the network device side.

[0364] As an example, the third processor obtains the second dataset from the upper layer, and the third processor is located at the first node.

[0365] As one embodiment, the fourth processor is located at the first node, or at the second node.

[0366] As one embodiment, the first processor is deployed in the CN (core network) domain MnF (Management Function), and / or the RAN (Radio Access Network) domain MnF, and / or the cross-domain management system.

[0367] As an example, the third processor constructs an AI model based on the target first type of parameter group, then inputs the second dataset into the constructed model to obtain the first type of output, and then sends the first type of output to the fourth processor.

[0368] As one embodiment, the third processor calculates the error between the first type of output and the actual data to determine the performance of the trained model; the actual data is the data received after the second dataset and passed from the first processor.

[0369] As an example, the first type of feedback is used to reflect the performance of the trained model; when the performance of the trained model fails to meet the requirements, the second processing opportunity will recalculate the target first type of parameter set.

[0370] As an example, when the error is too large or the update has not been performed for too long, the performance of the trained model is considered to be unsatisfactory.
