Description

Technical Field

[0001] This application relates to methods and apparatus in wireless communication systems, and more particularly to methods and apparatus for instructing the collection of data in wireless communication systems. Background Technology

[0002] With the popularization of AI (Artificial Intelligence) / ML (Machine Learning) technologies, in NR

[0003] In New Radio (or 5G) version 18, research on AI / ML technology was initiated to explore its application scenarios in wireless communication systems and how it impacts the evolution of existing network architectures and protocols. AI / ML is also a key candidate technology for the future evolution of 5G+ and 6G communication technologies, applicable to areas such as encoding, decoding, channel estimation, and radio resource management in traditional wireless communication. Compared to traditional processing methods, AI / ML is based on training, requires deployment, and involves inference output. Before using AI / ML functionality, the AI / ML model must first be trained, which requires collecting a large amount of training data. The specifications for AI models may extend beyond the scope of 3GPP (except for reference models used for performance calibration). The specific implementation methods for AI / ML model training and AI / ML inference may be determined by hardware equipment manufacturers or application providers, and may be based on classic models such as Transformer architecture, RNN (Recurrent Neural Network), CNN (Conventional Neural Network), or hybrid models composed of multiple models.

[0004] Depending on whether the UE (User Equipment) has established an RRC (Radio Resource Control) connection with the network, the UE can be in an RRC connected state, an RRC inactive state, or an RRC idle state. A UE in the RRC connected state needs to continuously monitor control signaling to enable service transmission. When a UE in the RRC connected state has not transmitted any service for an extended period, it can proactively enter the RRC idle state to conserve power. Summary of the Invention

[0005] Through research, the inventors discovered that in scenarios where data collection is performed on the UE side, if the UE discards the collected usable data when entering the RRC idle state, it not only wastes the power and computing resources consumed by the UE to collect data, but may also result in insufficient training data for AI / ML models, thereby affecting AI / ML performance.

[0006] To address the aforementioned problems, this application discloses a solution. Unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined. Furthermore, while this application is motivated by data collection and instruction for AI / ML model training, it can also be used for data collection and instruction for other purposes, including but not limited to performance monitoring, wireless network optimization such as MDT (Minimization of Drive Tests), wireless sensor networks, etc. In addition, using a unified solution for different technologies (including AI / ML model training data, AI / ML performance monitoring data, latency-insensitive data, etc.) helps reduce hardware complexity and cost. Specifically, the interpretation of terms, nouns, functions, and variables in this application (unless otherwise specified) can be found in the definitions of the 3GPP specification protocols TS38 and TS37 series.

[0007] This application discloses a method used in a first node of wireless communication, characterized by comprising:

[0008] Maintaining the first timer includes: starting or restarting the first timer when transmitting a MAC SDU via the DTCH logical channel, or the DCCH logical channel, or the CCCH logical channel;

[0009] When the time remaining before the expiration of the first timer is less than or not greater than the first threshold, and there is first type of collected data, a first message is sent, indicating that there is available data;

[0010] The first type of collected data is transmitted through the first SRB, which has a lower priority than SRB1; the logical channel for sending the first information is the first DCCH logical channel.

[0101] Example 1 illustrates a signal transmission flowchart of a first node according to an embodiment of this application, as shown in the attached diagram. Figure 1 As shown.

[0102] In Embodiment 1, the first node 100 maintains a first timer in step 101; in step 102, when the time remaining before the expiration of the first timer is less than or not greater than a first threshold, and there is first type of collected data, it sends a first message indicating that there is available data; wherein, maintaining the first timer includes: starting or restarting the first timer when transmitting MAC SDU through a DTCH logical channel, or a DCCH logical channel, or a CCCH logical channel; the first type of collected data is transmitted through a first SRB, the priority of the first SRB being lower than the priority of SRB1; the logical channel for sending the first message is a first DCCH logical channel.

[0103] As an example, the first timer is maintained in the MAC entity of the first node.

[0104] As an example, the MAC entity is targeted at MCG.

[0105] As an example, the MAC entity is targeted at SCG.

[0106] As an example, the first timer is used by the first node to determine whether it can actively enter the RRC idle state.

[0107] Specifically, when the first timer is running, the first node is in the RRC connected state; when the first timer expires, the first node enters the RRC idle state.

[0108] As an example, maintaining the first timer includes starting or restarting the first timer when transmitting a MAC SDU (Service Data Unit) through a DTCH (Dedicated Traffic Channel) logical channel (LCH), a DCCH (Dedicated Control Channel), or a CCCH (Common Control Channel) logical channel.

[0109] As one embodiment, the transmission includes sending or receiving.

[0110] Specifically,

[0111] When a MAC SDU of DTCH logic channel, DCCH logic channel, or CCCH logic is received;

[0112] or,

[0113] When sending a MAC SDU for the DTCH logical channel or the DCCH logical channel,

[0114] Start or restart the first timer.

[0115] As an example, when a MAC SDU of a multicast MTCH (MBS Traffic Channel) logical channel is received, the first timer is started or restarted.

[0116] As one embodiment, maintaining the first timer includes: indicating to the upper layer, i.e., the RRC layer, if the first timer expires.

[0117] As an example, the upper layer receives an indication that the first timer has expired and performs an operation to enter the RRC idle state.

[0118] As an example, the first timer is dataInactivityTimer.

[0119] As an example, when the time remaining before the expiration of the first timer is less than a first threshold and there is first type of collected data, a first message is sent, indicating that there is available data.

[0120] As an example, when the time remaining before the expiration of the first timer is no greater than a first threshold and there is first type of collected data, a first message is sent, indicating that there is available data.

[0133] As one embodiment, the time indicated by the first threshold includes the time for obtaining uplink transmission resources for sending the first MAC SDU; wherein the first MAC SDU includes at least a portion of the bits in the first information.

[0134] As one embodiment, the time indicated by the first threshold includes the time from sending the SR (scheduling request) to receiving the uplink transmission resource.

[0135] As an example, the first information is used to trigger the sending of the SR.

[0136] As an example, the resources occupied by the SR are indicated by the SR configuration, which indicates periodic PUCCH (Physical Uplink Control Channel) resources.

[0137] As an example, the SR configuration is proprietary.

[0138] As a sub-implementation of the above embodiments, the SR configuration corresponds to the first information.

[0139] As a sub-implementation of the above embodiments, the SR configuration corresponds to the first type of collected data reporting.

[0140] As an example, the SR configuration is not proprietary.

[0142] As one embodiment, the time remaining until the first timer expires being less than or not greater than a first threshold includes: the first timer expiring; wherein the time remaining until the first timer expires is equal to the first threshold, and the first threshold is 0.

[0143] As a sub-example of the above embodiments, the first threshold is not explicitly configured by the network.

[0144] As a sub-implementation of the above embodiment, the sending of the first information and the expiration of the first timer are atomic, and the expiration of the first timer is not used to indicate to the upper layer of the first node.

[0145] As an example, the first information is sent at the MAC sublayer.

[0146] As an example, the first type of collected data is stored in the AS (Access Stratum) memory of the first node.

[0147] As an example, the first type of collected data is stored in the RRC layer of the first node.

[0184] As an example, the priority of the first SRB is lower than that of SRB1.

[0185] The above embodiments can reduce the impact of uploading the first type of collected data on other signaling and / or data transmission.

[0186] As an example, the priority of the first SRB is the priority of the logical channel corresponding to the first SRB.

[0187] As an example, the priority of a radio bearer is used to determine the transmission priority of data carried in the radio bearer, which includes the first SRB.

[0222] Example 3

[0223] Example 3 illustrates a schematic diagram of a wireless protocol architecture for the user plane and control plane according to an embodiment of this application, as shown in the attached diagram. Figure 3 As shown. Figure 3 This is a schematic diagram illustrating an embodiment of a wireless protocol architecture for the user plane 350 and the control plane 300. Figure 3The radio protocol architecture of the UE and gNB 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 is responsible for the link between the UE and gNB 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 gNB on the network side. The PDCP sublayer 304 provides data encryption and integrity protection, and also provides cross-cell mobility support for the UE between gNBs. RLC sublayer 303 provides packet segmentation and reassembly, and implements retransmission of lost packets through ARQ (Automatic Repeat Request). RLC sublayer 303 also provides duplicate packet detection and protocol error detection.

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.The UE's radio protocol architecture in the user plane 350 may include some or all of the protocol sublayers of SDAP sublayer 356, PDCP sublayer 354, RLC sublayer 353, and MAC sublayer 352 at the L2 layer.

[0244] Example 4

[0245] Example 4 illustrates a hardware module schematic diagram of a communication device 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.

[0246] 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.

[0247] The second communication device 410 includes a controller / processor 475, a memory 476, a data source 477, 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.

[0248] 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 or from the data source 477 are provided to the controller / processor 475. The core network and data source 477 represent all protocol layers above the L2 layer. The controller / processor 475 implements the functionality of the L2 layer. 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 for 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.

[0249] 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 higher-layer data packets from the second communication device 410. 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.

[0250] In the transmission from the first communication device 450 to the second communication device 410, at the first communication device 450, upper-layer data packets are provided to the controller / processor 459 using a data source 467. 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 the logical and transport channels, 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.

[0251] 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 function. The controller / processor 475 implements the L2 layer function. The controller / processor 475 may be associated with a memory 476 storing 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 the upper-layer data packets from the first communication device 450. Upper-layer data packets from the controller / processor 475 can be provided to the core network or all protocol layers above the L2 layer, and various control signals can also be provided to the core network or L3 for L3 processing.

[0314] As a sub-implementation of the above embodiments, the first association identifier is assigned by the server of the first node.

[0315] As one embodiment, the first association identifier corresponding to an AI model includes: the first association identifier indicating the training dataset to which the first type of collected data belongs, and the training dataset being used to train the AI ​​model.

[0316] As an example, the first association identifier ensures that the training dataset used for the AI ​​model and the inference dataset used when performing inference through the AI ​​model are consistent.

[0317] As an example, the first measurement configuration indicates the model ID of an AI model.

[0318] As one embodiment, the first association identifier corresponding to an AI model includes: the second information includes an IE (Information Element) that simultaneously includes the first association identifier and the model identifier of the AI ​​model.

[0319] As an example, the results of the measurement are used to generate the first type of collected data.

[0320] As an example, all the results of the measurements are used to generate the first type of collected data.

[0321] As an example, a portion of the measurement results is used to generate the first type of collected data.

[0322] As an example, the results of the measurement are directly used to generate the first type of collected data.

[0323] As an example, the results of the measurement are processed and used to generate the first type of collected data.

[0324] As one embodiment, the processing includes layer 1 filtering.

[0325] As one example, the processing includes layer 3 filtering.

[0326] The two embodiments described above can avoid drastic changes in measurement results and improve the quality of collected data.

[0327] As one example, the process includes data filtering.

[0328] As one example, the data filtering includes removing singular or useless measurements.

[0329] Specifically, measurement results with a difference less than a threshold over a period of time are not used to generate the first type of collected data.

[0330] The two embodiments described above can improve the quality of collected data while saving storage space.

[0331] As an example, the first timer is started or restarted when transmitting a MAC SDU belonging to the DTCH logical channel, DCCH logical channel, or CCCH logical channel; after being started or restarted, the first timer is in a running state, and the first timer does not actively enter the RRC idle state while running.

[0332] As a sub-example of the above embodiment, the first node did not detect a radio link failure (RLF).

[0333] As one embodiment, sending the first information includes: the MAC entity of the first node sending a first MAC SDU, the first MAC SDU including at least a portion of the bits in the first information.

[0334] As an example, the MAC entity of the first node sends the first MAC SDU for the first DCCH logical channel.

[0335] As an example, the first MAC SDU includes all the bits included in the first information.

[0336] As an example, the first MAC SDU includes a portion of the bits included in the first information.

[0337] As an example, the MAC entity of the first node sends the first MAC SDU to the first DCCH logical channel to restart the first timer.

[0338] As one example, the first information is User Equipment Assistance Information (UEAssistanceInformation).

[0339] As one example, the first information indicates the reason for sending the first information.

[0340] As one example, the reason for sending the first information is that the first timer will expire.

[0341] As an example, a first UEInformationRequest is received through the first DCCH logical channel.

[0342] As a sub-implementation of the above embodiment, the first timer is restarted.

[0343] As an example, the first UEInformationRequest is a response to the first information.

[0344] As an example, the first UEInformationRequest requests the first node to send the first type of collected data.

[0345] As an example, the first UEInformationRequest includes a second field, the value of which is true.

[0346] As an example, the name of the second domain includes AI.

[0347] As an example, the name of the second domain includes DataCollection.

[0348] As an example, the name of the second field includes TrainingData.

[0349] As an example, in response to receiving the first UEInformationRequest, a first UEInformationResponse (User Equipment Information Response) is sent via the first SRB, the first UEInformationResponse including the first type of collected data.

[0350] As one embodiment, the first UEInformationResponse including the first type of collected data includes: the first UEInformationResponse including at least a portion of the entries in the first type of collected data.

[0351] As one embodiment, the first UEInformationResponse includes the first type of collected data, which includes: the first UEInformationResponse includes a portion of the entries in the first type of collected data, and the first UEInformationResponse indicates that there is available data.

[0352] The above embodiments allow the second node to continue requesting the reporting of the remaining first type of collected data by indicating to the second node that there is still available data.

[0353] As an example, both the first UEInformationRequest and the first UEInformationResponse are RRC layer messages.

[0354] As an example, the first SRB is associated with the second DCCH logical channel.

[0355] As an example, the first DCCH logical channel and the second DCCH logical channel are two different logical channels.

[0356] As an example, the priority of the first DCCH logical channel is different from that of the second DCCH logical channel.

[0357] As an example, the priority of the first DCCH logical channel is higher than that of the second DCCH logical channel.

[0358] As an example, the logical channel identifier of the first DCCH logical channel is different from the logical channel identifier of the second DCCH logical channel.

[0359] As one example, the second DCCH logical channel corresponds to the second logical channel identifier.

[0360] As one embodiment, the second logical channel identifier is 6, and the first SRB is configured in the MCG; or the second logical channel identifier is 7, and the first SRB is configured in the SCG.

[0361] As an example, the first UEInformationResponse is sent through the second DCCH logical channel to restart the first timer.

[0362] As one embodiment, the MAC entity of the first node sends a first MAC SDU, the first MAC SDU including at least a portion of the bits in the first information; wherein, the first timer is restarted; the most recent restart before the first timer was restarted was not triggered by sending a MAC SDU including the first information.

[0363] As an example, the first MAC SDU is sent and the first timer is restarted; if the first node does not receive a signaling request to report the first type of collected data before the expiration time of the first timer is less than or greater than the first threshold, the first node will not resend the first information.

[0364] Since whether the network requests the first node to report the first type of collected data is implemented by the network, the above two embodiments avoid the first node being unable to actively enter the RRC idle state due to the network not requesting the first node to report, thus wasting power.

[0365] As an example, measurements are performed in RRC connected state according to the first measurement configuration.

[0366] As an example, performing the measurement according to the first measurement configuration does not affect maintaining the first timer.

[0367] As an example, the measurement performed according to the first measurement configuration has ended when the first information is sent.

[0368] The above embodiments can report all collected data in a timely manner, avoiding the loss of all collected data when the first node enters the RRC idle state.

[0369] As an example, the measurement performed according to the first measurement configuration has not yet ended when the first information is sent.

[0370] The above embodiments can report some of the collected data in a timely manner, avoiding the discarding of some collected data when the first node enters the RRC idle state.

[0371] As an example, the first timer is considered to have expired after the MAC SDU including the first UEInformationResponse is sent; wherein, after the first information is sent, the MAC entity of the first node only transmits the MAC SDU belonging to the SRB1 and the MAC SDU belonging to the first SRB; wherein, the SRB1 only includes the first UEInformationRequest.

[0372] As a sub-implementation of the above embodiments, the first UEInformationResponse includes all data in the first type of collected data.

[0373] As a sub-implementation of the above embodiment, the first UEInformationResponse indicates that there is no remaining available data to be reported.

[0374] As a sub-implementation of the above embodiment, an instruction is sent to the upper layer of the first node, namely the RRC layer; upon receiving the instruction that the first timer has expired, the RRC layer performs the operation of entering the RRC idle state.

[0375] The above embodiment can enter the RRC idle state after the first node has sent the stored first type of collected data, thus achieving the beneficial effect of power saving.

[0376] Example 6

[0377] Example 6 illustrates a logical channel diagram for transmitting first information and transmitting first type of collected data according to an embodiment of this application, as shown in the attached diagram. Figure 6 As shown.

[0378] As an example, the first information is generated at the RRC layer and sent via SRB1, which is associated with the first DCCH logical channel.

[0379] As an example, the first UEInformationResponse is an RRC layer message, the first type of collected data is encapsulated in the RRC layer message and sent through the first SRB, and the first SRB is associated with the second PDCCH logical channel.

[0380] As an example, the first type of collected data is sent to the network side via the control plane (CP).
