Description

Technical Field

[0001] This application relates to methods and apparatus in wireless communication systems, and more particularly to methods and apparatus in wireless communication systems that support AI (Artificial Intelligence). Background Technology

[0002] The application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios place different performance requirements on the system. In order to meet the different performance requirements of various application scenarios, 3GPP (3rd Generation Partner Project) RAN...

[0003] At the 72nd plenary meeting of the 3GPP RAN (Radio Access Network), it was decided to conduct research on New Radio (NR) (or 5G). The WI (Work Item) for New Radio (NR) was adopted at the 75th plenary meeting, initiating standardization work for NR. In NR Release 18, research on AI technology was initiated to explore its impact on system performance and design. Compared to traditional processing methods, AI has characteristics such as being training-based and requiring deployment. Furthermore, AI is also a key candidate technology for future 6G communication. Summary of the Invention

[0004] The inventors discovered through research that AI models need to be trained before they can be deployed and applied. When model training occurs on the network side while data collection occurs on the UE (user equipment) side, the UE needs to report the collected data to the network. Since the collected training data is characterized by its large volume and insensitivity to transmission latency, how to report this collected training data requires further research.

[0005] To address the aforementioned issues, this application discloses a solution that enables data reporting via signaling radio bearer. Where there is no conflict, the embodiments and features in the first node of this application can be applied to the second node, and vice versa. Where there is no conflict, the embodiments and features in the embodiments of this application can be arbitrarily combined. Furthermore, although this application is initially intended for reporting training data collected for AI model training, it can also be used for reporting other data with similar characteristics. In addition, adopting a unified solution for different scenarios (including but not limited to reporting AI model training data) helps reduce hardware complexity and cost. Specifically, the explanations 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.

[0006] This application discloses a method used in a first node of wireless communication, characterized by comprising:

[0007] Receive the first UEInformationRequest;

[0008] In response to receiving the first UEInformationRequest, a first UEInformationResponse is sent via the target signaling radio bearer. The first UEInformationResponse includes the information requested by the first UEInformationRequest.

[0009] The candidate target signaling radio bearers include SRB1, SRB2, and a first SRB, with the first SRB having a lower priority than SRB2. The target signaling radio bearer depends on whether the first UEInformationResponse includes a first sub-message, which includes measurement results for AI. If the first UEInformationResponse includes the first sub-message, the target signaling radio bearer is the first SRB; if the first UEInformationResponse does not include the first sub-message, the target signaling radio bearer is either SRB1 or SRB2.

[0010] As an example, the measurement results for AI are obtained on the UE side and reported to the network.

[0011] As an example, the AI ​​includes at least one of AI or ML (Machine Learning).

[0012] As an example, UEInformationRequest and UEInformationResponse are common practices for networks to request information reported by UEs. The above method reports the measurement results for AI through the first UEInformationRequest and the first UEInformationResponse. Adopting a unified solution helps to reduce complexity and cost and simplify standardization work.

[0013] As an example, the first UEInformationRequest requests at least one piece of information.

[0014] As an example, when the first UEInformationRequest requests one piece of information, the first UEInformationResponse includes the one piece of information requested by the first UEInformationRequest; when the first UEInformationRequest requests multiple pieces of information, the first UEInformationResponse includes at least one of the multiple pieces of information requested by the first UEInformationRequest.

[0015] As one example, the different information requested by the first UEInformationRequest has different priorities.

[0016] As an example, when the first UEInformationResponse includes at least one piece of information with different priorities requested by the first UEInformationRequest, it is necessary to study how to determine the signaling radio bearer that sends the first UEInformationResponse.

[0017] As an example, the first SRB (Signaling Radio Bearer) has a lower priority than SRB1 (Signaling Radio Bearer 1) and lower priority than SRB2 (Signaling Radio Bearer 2).

[0018] As an example, the priority of an SRB is used for resource allocation in the LCP (Logical Channel Prioritization) process, wherein the SRB is the first SRB, or SRB1, or SRB2.

[0019] As an example, the above method introduces a lower-priority signaling radio bearer through the first SRB, which can satisfy the transmission of lower-priority signaling.

[0020] As an example, the above method determines the target signaling radio bearer by whether the first sub-message is included in the first UEInformationResponse. This allows information of different priorities to be sent through signaling radio bearers of different priorities, avoiding the transmission of lower priority information through higher priority signaling radio bearers, which could affect other signaling or other data transmissions.

[0021] According to one aspect of this application, the above method is characterized by:

[0022] If the first flag is included in the first UE variable, the first UEInformationResponse includes the first sub-message;

[0023] Wherein, the first UEInformationRequest requests the measurement results of AI; the first identifier is RPLMN, and the first identifier is included in the plmn-IdentityList field of the first UE variable, or the first identifier is the currently registered SNPN, and the first identifier is included in the snpn-ConfigIDList field of the first UE variable.

[0024] As an example, when the first flag is included in the first UE variable, the first UEInformationResponse includes the first sub-message, which can improve information security.

[0025] According to one aspect of this application, the above method is characterized by:

[0026] Set the first field of the first sub-message to include at least one measurement result stored in the first UE variable for AI purposes;

[0027] Wherein, the at least one measurement result for AI included in the first domain is arranged in chronological order of recording time, or in order of priority from high to low.

[0028] As an example, the above method applies when the first field of the first sub-message is configured to include all the measurement results for AI stored in the first UE variable, and also applies when the first field of the first sub-message is configured to include a portion of the measurement results for AI stored in the first UE variable.

[0029] As an example, in the above method, the measurement results of at least one AI included in the first domain are arranged in order of priority from high to low, and the measurement results with higher priority can be sent first to improve system performance.

[0030] According to one aspect of this application, the above method is characterized by:

[0031] The first sub-message includes a second field, which indicates that the measurement results are available for AI purposes;

[0032] The first UE variable includes additional measurement results for AI that have not yet been included in the first sub-message.

[0033] As an example, when the first field of the first sub-message is set to include the portion of the measurement results for AI stored in the first UE variable, the above method indicates to the base station by including the second field in the first sub-message, so that the base station can continue to request the UE when it needs to obtain the remaining additional measurement results for AI.

[0034] According to one aspect of this application, the above method is characterized by:

[0035] After the first node's lower layer confirms that the first UEInformationResponse has been successfully transmitted, the measurement results for AI included in the first UE variable are deleted.

[0036] As one embodiment, the lower layer is the physical layer, or the MAC (Medium Access Control) sublayer, or the RLC (Radio Link Control) sublayer.

[0037] As an example, the above method can save memory space for the first node.

[0038] According to one aspect of this application, the above method is characterized by:

[0039] Send a first message indicating that the first UE variable includes the measurement results available for AI;

[0040] The first message is used to trigger the first UEInformationRequest.

[0041] As an example, the above method instructs the base station via the first message so that the base station can request the measurement results from the UE when it needs to obtain them for AI.

[0042] According to one aspect of this application, the above method is characterized by:

[0043] The identifier of the first SRB is 4, or a positive integer greater than 4.

[0044] As an example, the first SRB is SRB4 (Signaling Radio Bearer 4).

[0045] As an example, the first SRB is SRBx (signaling radio bearer x), where x is a positive integer greater than 4.

[0046] This application discloses a method used in a second node for wireless communication, characterized by comprising:

[0047] Send the first UEInformationRequest;

The first UEInformationResponse is a response to the first UEInformationRequest. Candidates for the target signaling radio bearer include SRB1, SRB2, and a first SRB, with the first SRB having a lower priority than SRB2. The target signaling radio bearer depends on whether the first UEInformationResponse includes a first sub-message, which includes measurement results for AI. If the first UEInformationResponse includes the first sub-message, the target signaling radio bearer is the first SRB. If the first UEInformationResponse does not include the first sub-message, the target signaling radio bearer is either SRB1 or SRB2.

[0056] The first sub-message includes a second field indicating that the measurement results are available for AI purposes;

[0057] The first UE variable includes additional measurement results for AI that have not yet been included in the first sub-message.

[0058] According to one aspect of this application, the above method is characterized by:

[0059] After the lower layer of the recipient of the first UEInformationRequest confirms that the first UEInformationResponse has been successfully transmitted, the measurement results for AI included in the first UE variables are deleted.

[0141] As an example, the priority of an SRB is the priority of the logical channel serving the SRB.

[0142] Specifically, the higher the priority value of a logical channel, the lower the priority of that logical channel.

[0143] Specifically, the priority value of a logical channel is an integer between 1 and 16, including 1 and 16.

[0144] As an example, the priority value of SRB1 is 1, and the priority value of SRB2 is 3.

[0145] As an example, the priority value of the first SRB is greater than 3.

[0148] As an example, if the first UEInformationResponse includes the first sub-message, the target signaling radio bearer is the first SRB; if the first UEInformationResponse does not include the first sub-message but includes logMeasReport, the target signaling radio bearer is the SRB2; if the first UEInformationResponse does not include the first sub-message or the logMeasReport, the target signaling radio bearer is the SRB1.

[0195] Example 3

[0196] 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. MAC sublayer 302 provides mapping between logical channels 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 UEs.

The radio protocol architecture of user plane 350 includes Layer 1 (L1 layer) and Layer 2 (L2 layer). The radio protocol architecture 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.The radio protocol architecture of the UE 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. Although not illustrated, the UE may also 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.).

[0205] Example 4

[0206] 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.

[0207] 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.

[0208] 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.

[0209] 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.

[0210] 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.

[0211] 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.

[0212] 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.

[0285] As an example, if the first UEInformationResponse includes the first sub-message, the target signaling radio bearer is the first SRB; otherwise, if the first UEInformationResponse includes logMeasReport, the target signaling radio bearer is the SRB2; otherwise, the target signaling radio bearer is the SRB1. Wherein, "otherwise, if the first UEInformationResponse includes logMeasReport, the target signaling radio bearer is the SRB2" includes: if the first UEInformationResponse does not include the first sub-message but includes logMeasReport, the target signaling radio bearer is the SRB2; "otherwise, the target signaling radio bearer is the SRB1" includes: if the first UEInformationResponse does not include either the first sub-message or logMeasReport, the target signaling radio bearer is the SRB1.

[0286] As an example, when the first UEInformationResponse includes the first sub-message, the first UEInformationResponse is sent through the first SRB regardless of whether the first UEInformationResponse includes other sub-messages.

[0287] As a sub-implementation of the above embodiments, the method reduces the sending priority of the other sub-messages to the same level as the sending priority of the first sub-message, which can meet the transmission requirements of other high-priority signaling or data.

[0288] As an example, if the first UEInformationResponse does not include the first sub-message, but the first UEInformationResponse includes logMeasReport, then regardless of whether the first UEInformationResponse includes other sub-messages, the first UEInformationResponse is sent via SRB2.

[0289] As a sub-implementation of the above embodiments, the method reduces the sending priority of the other sub-messages to the same level as the sending priority of the logMeasReport, which can meet the transmission requirements of other high-priority signaling or data.

[0290] This application sends the first UEInformationRequest request information through a base station. The UE multiplexes information with the same or different priorities into the first UEInformationResponse. The signaling radio bearer for sending the first UEInformationResponse is determined by the lowest priority information multiplexed in the first UEInformationResponse. This allows for flexible adjustment of information transmission priorities, improving system performance and transmission efficiency.

[0291] Example 7

[0292] Example 7 illustrates a processing flowchart in the first node according to an embodiment of this application, as shown in the attached diagram. Figure 7 As shown.

[0293] In Example 7, the first node receives a first UEInformationRequest in step S701; in step S702, it sets the first field of the first sub-message to include at least one measurement result for AI stored in the first UE variable; in step S703, it determines whether the first UE variable also includes additional measurement results for AI that have not yet been included in the first sub-message; if yes, it executes step S704; if no, it executes step S705; in step S704, it includes a second field in the first sub-message; in step S705, it sends a first UEInformationResponse; in step S706, it determines whether the lower layer confirms that the first UEInformationResponse has been successfully transmitted; if yes, it executes step S707; if no, it jumps back to step S706; in step S707, it deletes the measurement results for AI already included in the first sub-message from the first UE variable. Example 7 is applicable to the case where the first sub-message is included in the first UEInformationResponse.

[0294] As one embodiment, the first transmitter includes a first field in the first sub-message.

[0297] As an example, the first field of the first sub-message is set to include at least one measurement result stored in the first UE variable for AI purposes.

[0298] As an example, the at least one measurement result for AI stored in the first UE variable is set into the first field of the first sub-message.

[0299] Specifically, at least one entry corresponding to the measurement result for AI is stored in the first UE variable, and at least one entry included in the first field of the first sub-message is set as the at least one entry in the first UE variable.

[0300] Specifically, the first UE variable includes 10 entries, which store 10 measurement results for AI; the first field of the first sub-message includes 10 entries, which are respectively set to the 10 entries included in the first UE variable, that is, the 10 entries included in the first UE variable are copied to the 10 entries included in the first UE variable.

[0301] As an example, the at least one measurement result for AI stored in the first UE variable is set into the first field of the first sub-message in the order of recording time.

[0302] As an example, at least one measurement result for AI stored in the first UE variable is set into the first field of the first sub-message in descending order of priority of the measurement result for AI.

[0303] As one embodiment, the first transmitter sets at least one measurement result for AI stored in the first UE variable into the first field of the first sub-message in order of recording time from most recent to oldest.

[0304] Specifically, the most recently recorded measurement result for AI is first set in the first field of the first sub-message, then the second most recently recorded measurement result for AI is set in the first field of the first sub-message, then the third most recently recorded measurement result, and so on, without further explanation.

[0305] As an example, when the first UE variable includes additional measurement results for AI that have not yet been included in the first field of the first sub-message, the first sub-message includes a second field indicating that the measurement results for AI are available.

[0306] Specifically, the first UE variable includes 10 entries, which store 10 measurement results for AI; the first field of the first sub-message includes 8 entries, which are respectively set to the 8 entries included in the first UE variable. There are 2 entries in the first UE variable that are not included in the first field of the first sub-message. At this time, the second field is included in the first sub-message to indicate that there are still available entries in the first UE variable; wherein, each entry corresponds to a measurement result for AI.

[0307] As an example, the second field includes 1 bit.

[0308] As an example, the second field is set to true.

[0309] As one embodiment, the first transmitter receives a first indication from the lower layer of the first node, the first indication confirming that the first UEInformationResponse was successfully transmitted.

[0310] As an example, after the lower layer of the first node confirms that the first UEInformationResponse has been successfully transmitted, the measurement results for AI included in the first field of the first sub-message, which are already included in the first UE variable, are deleted.

[0311] Specifically, the first UE variable includes 10 entries, each storing 10 measurement results for AI; the first field of the first sub-message includes 10 entries, each set to one of the 10 entries included in the first UE variable; the first sub-message is included in the first UEInformationResponse and is sent; after the first UEInformationResponse is confirmed by the lower layer of the first node to have been successfully transmitted, the 10 entries included in the first UE variable and sent in the first sub-message are deleted.

A method used in a first node of wireless communication, characterized in that, include: Receive the first UEInformationRequest; In response to receiving the first UEInformationRequest, a first UEInformationResponse is sent via the target signaling radio bearer. The first UEInformationResponse includes the information requested by the first UEInformationRequest. The candidate target signaling radio bearers include SRB1, SRB2, and a first SRB, with the first SRB having a lower priority than SRB2. The target signaling radio bearer depends on whether the first UEInformationResponse includes a first sub-message, which includes measurement results for AI. If the first UEInformationResponse includes the first sub-message, the target signaling radio bearer is the first SRB; if the first UEInformationResponse does not include the first sub-message, the target signaling radio bearer is either SRB1 or SRB2.

10. A method used in a second node for wireless communication, characterized in that, include: Send the first UEInformationRequest; The first UEInformationResponse is received via the target signaling radio bearer, and the first UEInformationResponse includes information requested by the first UEInformationRequest. Wherein, the first UEInformationResponse is a response to the first UEInformationRequest; the candidates for the target signaling radio bearer include SRB1, SRB2 and a first SRB, with the first SRB having a lower priority than SRB2; the target signaling radio bearer depends on whether the first UEInformationResponse includes a first sub-message, the first sub-message including measurement results for AI; if the first UEInformationResponse includes the first sub-message, the target signaling radio bearer is the first SRB; if the first UEInformationResponse does not include the first sub-message, the target signaling radio bearer is either SRB1 or SRB2.
