Description

A method and apparatus for data transmission in wireless communication.

[0001] This application claims priority to Chinese Patent Application No. 202411617967.4, filed on November 12, 2024, entitled "A method and apparatus for data transmission in wireless communication", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to methods and apparatus for data transmission. Background Technology

[0003] The 3GPP (3rd Generation Partnership Project) protocol supports SON (Self-Organizing Networks) / MDT (Minimization of Drive Test), including Immediate MDT and Logged MDT. For Logged MDT, to reduce the reporting of measurement information, the UE (User Equipment) can store measurement information in UE variables. Whenever the UE performs RRC (Radio Resource Control) connection reconfiguration, reestablishment, resume, or establishment, it can indicate the storage of the corresponding measurement information in the message confirming the successful completion of the RRC reconfiguration, reestablishment, resume, or establishment. Based on this indication, the base station requests the UE to report the corresponding measurement information via a UEInformationRequest message. In response, the UE sends the corresponding measurement information to the base station via a UEInformationResponse message.

[0004] 3GPP Release 19 launched the WI: "For AI (Artificial Intelligence) / ML (Machine Learning) of NR Air Interface". Currently, the following consensus has been reached regarding data collection for network-side models: UEInformationRequest messages / UEInformationResponse messages are used for on-demand AI / ML training data collection, and a low-priority SRB (Signalling Radio Bearer) is used. Discussions will continue on whether to adopt SRB4 or a new SRB.

[0005] Since the specifications of AI models may extend beyond the scope of 3GPP (except for reference models used for performance calibration), the specific implementation of AI / ML training and AI / ML inference may be determined by the hardware equipment vendors themselves. It may be based on classic models such as Transformer architecture, RNN (Recurrent Neural Network), CNN (Conventional Neural Networks), or a hybrid model composed of multiple models. Summary of the Invention

[0006] Through research, the inventors discovered that existing technologies focus on data collection for the network-side model of the UE in the RRC_CONNECTED state. However, how to provide training data for the network-side model when the UE leaves the RRC_CONNECTED state is a problem that needs to be studied.

[0007] To address the aforementioned problems, this application provides a solution. While AI / ML is used as an example in the problem description, this application is also applicable to non-AI / ML scenarios, such as application-layer measurement, achieving similar technical effects to AI / ML. Similarly, while training data is used as an example in the problem description, this application is also applicable to inference data or reinforcement learning data, achieving similar technical effects to training data. Furthermore, adopting a unified design scheme for different scenarios helps reduce hardware complexity and cost. It should be noted that, unless otherwise specified, embodiments and features in any node of this application can be applied to any other node. Furthermore, embodiments and features in any node of this application can be arbitrarily combined.

[0008] As an example, the interpretation of terms in this application is based on the definitions in the 3GPP specification protocol TS38 series.

[0009] As an example, the interpretation of terms in this application is based on the definitions in the 3GPP specification protocol TS37 series.

[0010] It should be noted that, unless otherwise specified, the embodiments and features described in the terminal of this application can be applied to the base station. Unless otherwise specified, the embodiments and features described in the base station of this application can be applied to the terminal. Unless otherwise specified, the embodiments and features described in the embodiments of this application can be arbitrarily combined with each other.

[0011] This application discloses a method used in a terminal, characterized by comprising:

[0012] Receive the first RRC message;

[0013] As a response to the receipt of the first RRC message, it enters the RRC_INACTIVE state;

[0014] In the RRC_INACTIVE state, as a response to the satisfaction of the first set of conditions, a first process is initiated, the first process including sending a second RRC message;

[0015] Along with sending the second RRC message, at least one radio bearer is restored;

[0016] Wherein, the at least one radio bearer includes a first SRB, the identifier of the first SRB is greater than 2; the first condition set includes at least the first RRC message includes a first information block, the first information block is configured with SDT (Small Data Transmission).

[0017] Considering that the UE can perform SDT in the RRC_INACTIVE state, however, in the existing technology, SDT can only be performed through DRB or SRB2; the above method performs SDT through the first SRB with an identifier greater than 2; when the uplink data is mapped to the first SRB, it avoids entering the RRC_CONNECTED state, reduces signaling overhead and saves UE power consumption.

[0018] According to one aspect of this application, the first information block includes a first field indicating that the first SRB is configured for SDT.

[0019] The above method solves the problem of how to determine whether SDT has been configured as the first SRB, and it is simple to implement.

[0020] According to one aspect of this application, it is characterized by comprising:

[0021] In the RRC_INACTIVE state, a third RRC message is sent through the first SRB;

[0022] The third RRC message includes the measurement results for the first measurement configuration; the first RRC message includes the first measurement configuration.

[0023] The above method further specifies that the measurement results transmitted on the first SRB are for the first measurement configuration in the first RRC message. This is beneficial for the transmission of measurement results in the RRC_INACTIVE state.

[0024] According to one aspect of this application, it is characterized by comprising:

[0025] In the RRC_INACTIVE state, target measurement information is stored in the first storage unit; wherein the measurement result configured for the first measurement includes at least a portion of the target measurement information;

[0026] Wherein, storing the target measurement information in the RRC_INACTIVE state depends on the first measurement configuration; the first RRC message includes the first measurement configuration.

[0027] The above method further defines the measurement result for the first measurement configuration as including at least a portion of the target measurement information in the first storage unit. Storing the target measurement information in the first storage unit helps reduce the frequency of reporting.

[0028] According to one aspect of this application, the first condition set includes any event in a first event set being satisfied; wherein the first RRC message configures at least one event in the first event set, the first event set including at least a first event; the first event depends on the first measurement configuration, or the first event depends on the first storage unit.

[0029] The above method takes into account that the first SRB is used to report the measurement results for the first measurement configuration, and further limits the triggering conditions of the first process.

[0030] According to one aspect of this application, it is characterized by comprising:

[0031] Receive an SIB1 message; wherein the SIB1 message indicates a first data volume threshold;

[0032] The first condition set includes all pending data on the uplink mapped to the at least one radio bearer; whether the first condition set includes data on the at least one radio bearer not exceeding the first data volume threshold depends on whether all pending data on the uplink is mapped to the first SRB; wherein,

[0033] If all of the pending data on the uplink is mapped to the first SRB, the first condition set does not include the amount of data on the at least one radio bearer not exceeding the first data amount threshold;

[0034] If all of the pending data on the uplink is not mapped to the first SRB, the first condition set includes the amount of data on the at least one radio bearer not exceeding the first data amount threshold.

[0035] The above method takes into account the large amount of data on the first SRB. For the case where all the pending data on the uplink is mapped to the first SRB, the limitation of the first data volume threshold is removed, which is beneficial to the transmission of data on the first SRB.

[0036] According to one aspect of this application, the identifier of the first SRB is 4.

[0037] The above method reuses existing SRBs and avoids introducing new SRBs.

[0038] According to one aspect of this application, the identifier of the first SRB is greater than 5.

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 in 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. The L1 layer will be referred to herein as PHY 301. Layer 2 (L2 layer) 305 is above PHY 301 and includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304.

[0185] Example 4

[0186] Embodiment 4 illustrates a schematic diagram of a first communication device and a second communication device according to this application, as shown in Figure 4. Figure 4 is a block diagram of a first communication device 450 and a second communication device 410 communicating with each other in an access network.

[0187] 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.

[0188] 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.

[0189] In the transmission from the second communication device 410 to the first communication device 450, at the second communication device 410, upper-layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements L2 layer functionality. In the transmission from the second communication device 410 to the first communication device 450, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the first communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmitting lost packets and signaling to the first communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for the L1 layer (i.e., the physical layer). Transmit processor 416 performs encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 410, and mapping of signal clusters based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), M-Phase Shift Keying (M-PSK), M-QAM). Multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based and non-codebook-based precoding, and beamforming processing, generating one or more spatial streams. Transmit processor 416 then maps each spatial stream to subcarriers, multiplexes it with a reference signal (e.g., a pilot) in the time and / or frequency domains, and subsequently uses inverse fast Fourier transform (IFFT) to generate a physical channel carrying the time-domain multicarrier symbol stream. Multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multicarrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multi-antenna transmitter processor 471 into an radio frequency stream, which is then provided to different antennas 420.

[0190] In the transmission from the second communication device 410 to the first communication device 450, at the first communication device 450, each receiver 454 receives a signal through its corresponding antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multicarrier symbol stream, which is then provided to the receiver processor 456. The receiver processor 456 and the multi-antenna receiver processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiver processor 458 performs receive analog precoding / beamforming operations on the baseband multicarrier symbol stream from the receiver 454. The receiver processor 456 uses a Fast Fourier Transform (FFT) to convert the baseband multicarrier symbol stream after the receive analog precoding / beamforming operations from the time domain to the frequency domain. In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receiver processor 456, where the reference signal is used for channel estimation, and the data signal is recovered in the multi-antenna receiver processor 458 after multi-antenna detection to recover any spatial stream destined for the first communication device 450. Symbols on each spatial stream are demodulated and recovered in the receive processor 456, generating soft decisions. The receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper-layer data and control signals transmitted by the second communication device 410 over the physical channel. The upper-layer data and control signals are then provided to the controller / processor 459. The controller / processor 459 implements the functions of Layer 2. The controller / processor 459 may be associated with a memory 460 storing program code and data. The memory 460 may be referred to as computer-readable media. In the transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transport and logical channels to recover upper-layer data packets from the core network. The upper-layer data packets are then provided to all protocol layers above Layer 2. Various control signals may also be provided to Layer 3 for Layer 3 processing.

[0191] In the transmission from the first communication device 450 to the second communication device 410, at the first communication device 450, a data source 467 is used to provide upper-layer data packets to the controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission functions at the second communication device 410 described in the transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocation, implementing L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for retransmitting lost packets and signaling to the second communication device 410. Transmit processor 468 performs modulation mapping and channel coding processing, while multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming processing. Subsequently, transmit processor 468 modulates the generated spatial stream into a multi-carrier / single-carrier symbol stream. After analog precoding / beamforming operations in multi-antenna transmit processor 457, the stream is provided to different antennas 452 via transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by multi-antenna transmit processor 457 into a radio frequency symbol stream before providing it to antenna 452.

[0192] In the transmission from the first communication device 450 to the second communication device 410, the function at the second communication device 410 is similar to the receiving function at the first communication device 450 described in the transmission from the second communication device 410 to the first communication device 450. Each receiver 418 receives radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals into baseband signals, and provides the baseband signals to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and the multi-antenna receiving processor 472 jointly implement the L1 layer functions. The controller / processor 475 implements the L2 layer functions. The controller / processor 475 may be associated with a memory 476 that stores program code and data. The memory 476 may be referred to as computer-readable media. In the transmission from the first communication device 450 to the second communication device 410, the controller / processor 475 provides multiplexing between the transmission and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper-layer data packets from the UE 450. Upper-layer packets from the controller / processor 475 can be provided to the core network.
