Description

Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to methods and apparatus for configuring logical channels. Background Technology

[0002] Logical Channel Prioritization (LCP) is used for resource allocation. LCP is applied whenever a new transmission is performed. Each logical channel maintains a value Bj; Bj is initially 0. Before each LCP execution, Bj is incremented by PBR (Prioritized Bit Rate) × T. During resource allocation, logical channels with Bj greater than 0 are given priority for resource allocation. PBR can be set to infinity; in this case, resources are allocated to all available data on the corresponding logical channel before satisfying the PBR of lower-priority logical channels. After a logical channel is allocated resources, Bj is decremented. If there are remaining resources, Bj is ignored, and resources are allocated to logical channels in a strict descending priority order. Logical channels with the same priority should receive the same service.

[0003] Since the specifications of AI models may extend beyond the scope of 3GPP (besides the reference model 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 Network), or a hybrid model composed of multiple models. Summary of the Invention

[0004] In existing technologies, to ensure control plane signaling transmission, the priority bit rate of a logical channel for any SRB (Signalling Radio Bearer) can only be set to infinity. This ensures that data on this logical channel is prioritized for transmission during resource allocation, and the size of the prioritized allocated resources is not limited by Bj. However, with the continuous development of communication technologies, some control plane signaling has relatively low priority, especially with the introduction of AI / ML technologies. On the one hand, the size of training data is large; on the other hand, the latency requirements for training data are relatively low compared to traditional data. If existing technologies are still used when reporting training data via SRB, traditional data may not be allocated resources in a timely manner, affecting system performance. Therefore, it is necessary to optimize the logical channel for SRB.

[0005] To address the aforementioned issues, 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 lower-priority SRBs or SRBs with lower latency requirements, achieving similar technical effects to AI / ML systems. Furthermore, using a unified solution across different scenarios helps reduce hardware complexity and cost.

[0006] As an example, the interpretation of terms in this application is based on the definitions in the 3GPP specification protocol TS38 series.

[0007] It should be noted that, unless otherwise specified, the embodiments and features in any node of this application can be applied to any other node. Furthermore, unless otherwise specified, the embodiments and features in any embodiment of this application can be arbitrarily combined with each other.

[0008] This application discloses a method used in a first node of wireless communication, characterized by comprising:

[0009] Receive a first signaling; wherein the first signaling indicates the priority bit rate of a first logical channel, and the first logical channel is associated with a first SRB;

[0010] Wherein, the candidate priority bit rate of the first logical channel is a value in kilobytes per second (kBps), and the candidate priority bit rate of the first logical channel depends on the type of the first SRB; the dependency of the candidate priority bit rate of the first logical channel on the type of the first SRB includes:

[0011] If the first SRB is a first type SRB, the candidates for the priority bit rate of the first logical channel include a first value, which is finite;

[0012] If the first SRB is a second type SRB, the candidates for the priority bit rate of the first logical channel only include infinity;

[0013] Wherein, the first type of SRB and the second type of SRB are different; the second type of SRB is any one of a plurality of SRBs, the plurality of SRBs including at least SRB1.

[0014] The above method reduces the impact on data on logical channels associated with DRBs (Data Radio Bearers) by setting the priority bit rate of the logical channel associated with the first type of SRB to a limited value.

[0015] The above method allows for a limited number of candidate priority bit rates for the logical channels associated with the first type of SRB, which is beneficial for adjusting the size of the resources allocated to the first type of SRB.

[0016] According to one aspect of this application, if the first SRB is the first type of SRB, the first logical channel is not configured as a PUCCH (Physical Uplink Control Channel) resource for an SR (Scheduling Request).

[0017] Considering that AI / ML training data and / or inference data do not have high latency requirements, the above method can save PUCCH overhead and air interface overhead by not configuring the first logical channel as SR PUCCH.

[0018] According to one aspect of this application, the first signaling indicates the priority of the first logical channel; wherein, if the first SRB is the first type of SRB, the priority of the first logical channel is lower than the priority of any one of the plurality of SRBs.

[0019] Considering the low priority of AI / ML training data and / or inference data, the above method ensures that data on other SRBs is transmitted preferentially by having the first logical channel have a lower priority than any of the plurality of SRBs.

[0020] According to one aspect of this application, the first signaling includes a first field indicating the HARQ mode allowed by the HARQ (Hybrid Automatic Repeat Request) procedure mapped to the first logical channel.

[0021] Considering that AI / ML training data and / or inference data have relatively low requirements for reliable transmission, the above method provides flexibility in HARQ configuration for the first logical channel by configuring HARQ mode for the first logical channel.

[0022] According to one aspect of this application, the first signaling includes a second field indicating that segmentation of RRC messages on the first type SRB is enabled; wherein the first SRB is the first type SRB.

[0023] Given the large size of AI / ML training and / or inference data, the above method enables the segmentation of RRC messages on the first type of SRB, which is beneficial for the transmission of AI / ML training and / or inference data.

[0024] According to one aspect of this application, the data from the first logical channel is given priority in a lower order than the data from the second logical channel; wherein the first SRB is the first type of SRB, and the second logical channel is configured for the DRB.

[0025] The above methods help to prevent data on the DRB from being unable to be allocated resources or being allocated too late.

[0026] According to one aspect of this application, if the first SRB is the first type of SRB, the priority bit rate of the first logical channel depends on whether there is first type of data on the first logical channel; the dependence of the priority bit rate of the first logical channel on whether there is first type of data on the first logical channel includes:

[0027] When the first type of data is on the first logical channel, the priority bit rate of the first logical channel is the first value;

[0028] When there is no data of the first type on the first logical channel, the priority bit rate of the first logical channel is infinitely large;

[0029] The candidates for the priority bit rate of the first logical channel include the first value and infinity.

[0030] The above method can support the first type of data and other data to share the first logical channel, thereby expanding the functionality of the first logical channel.

[0031] According to one aspect of this application, it is characterized by comprising:

[0032] In the resource allocation, resources are allocated for at least the first logical channel; a first MAC (Medium Access Control) PDU (Protocol Data Unit) is sent; wherein the first MAC PDU depends on the resource allocation;

[0033] Wherein, the size of the resource preferentially allocated to the first logical channel in the resource allocation depends on the type of the first SRB; the size of the resource preferentially allocated to the first logical channel in the resource allocation depends on the type of the first SRB, including:

[0034] If the first SRB is the first type of SRB, the size of the resource to which the first logical channel is preferentially allocated in the resource allocation depends on the Bj of the first logical channel.

[0035] If the first SRB is the second type of SRB, the size of the resource to which the first logical channel is preferentially allocated in the resource allocation does not depend on the Bj of the first logical channel.

[0117] 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.

[0118] Example 1

[0119] Example 1 illustrates a flowchart of the transmission of a first node according to an embodiment of this application, as shown in the attached diagram. Figure 1 As shown. (Attached) Figure 1 In the diagram, each box represents a step. It is particularly important to emphasize that the order of the boxes does not represent the chronological order of the steps they represent.

[0120] In Embodiment 1, the first node in this application receives first signaling in step 101; wherein the first signaling indicates the priority bit rate of a first logical channel, the first logical channel being associated with a first SRB; wherein the candidate priority bit rate of the first logical channel is a value in kilobytes per second, and the candidate priority bit rate of the first logical channel depends on the type of the first SRB; the dependency of the candidate priority bit rate of the first logical channel on the type of the first SRB includes:

[0121] If the first SRB is a first type SRB, the candidates for the priority bit rate of the first logical channel include a first value, which is finite;

[0122] If the first SRB is a second type SRB, the candidates for the priority bit rate of the first logical channel only include infinity;

[0123] Wherein, the first type of SRB and the second type of SRB are different; the second type of SRB is any one of a plurality of SRBs, the plurality of SRBs including at least SRB1.

[0124] As one embodiment, the association of the first logical channel and the first SRB includes: the first logical channel being configured to the first SRB.

[0125] As one embodiment, the association of the first logical channel and the first SRB includes: the first SRB being configured with the first logical channel.

[0126] As one embodiment, associating the first logical channel with the first SRB includes: the first SRB and the first logical channel being associated with the same LogicalChannelIdentity.

[0128] As one embodiment, associating the first logical channel with the first SRB includes: an RLC-BearerConfig IE indicating that the first logical channel is associated with the first SRB.

[0129] As an example, the RLC-BearerConfig IE indicates the identifier of the first logical channel and the identifier of the first SRB.

[0130] As one embodiment, the first signaling includes at least one RRC (Radio Resource Control) message.

[0131] As an example, the first signaling includes at least one RRC IE (Information Element).

[0132] As one embodiment, the first signaling includes at least one RRC field.

[0133] As one embodiment, the first signaling includes a LogicalChannelConfig IE, which indicates the priority bit rate of the first logical channel.

[0134] As an example, the first signaling is a LogicalChannelConfig IE.

[0135] As one embodiment, the first signaling includes an RLC-BearerConfig IE, which indicates the priority bit rate of the first logical channel.

[0136] As an example, the first signaling is an RLC-BearerConfig IE.

[0137] As one embodiment, the first signaling includes a target field that indicates the priority bit rate of the first logical channel.

[0138] As an example, the target field is a prioritizedBitRate field.

[0139] As an example, the target field is not the prioritisedBitRate field.

[0140] As an example, the target field is not the prioritisedBitRate field; the name of the target field includes prioritisedBitRate.

[0141] As a sub-implementation of the above embodiment, the target domain is a prioritisedBitRate-r19 domain.

[0142] As a sub-implementation of the above embodiment, the target domain is a prioritisedBitRate-r20 domain.

[0143] As a sub-implementation of the above embodiment, the target domain is a prioritisedBitRate-v1900 domain.

[0144] As a sub-implementation of the above embodiment, the target domain is a prioritisedBitRate-v2000 domain.

[0145] As an example, the first signaling includes an SRB-Identity, which indicates the first SRB.

[0146] As an example, the first signaling includes a MAC CE (Control Element) indicating the priority bit rate of the first logical channel.

[0147] As one embodiment, the first signaling includes a MAC CE, which indicates the priority bit rate of the first logical channel from a plurality of priority bit rates.

[0148] The above method facilitates the dynamic adjustment of the priority bit rate of the first logical channel and saves the overhead of the physical layer control channel.

[0149] As an example, the first signaling includes a DCI (Downlink Control Information) indicating the priority bit rate of the first logical channel.

[0150] As one embodiment, the first signaling includes a DCI that indicates the priority bit rate of the first logical channel from a plurality of priority bit rates.

[0151] The above method facilitates the dynamic adjustment of the priority bit rate of the first logical channel and reduces the latency.

[0152] As an example, the first type of SRB is used for the control channel.

[0153] As an example, the first type of SRB is used for DCCH (Dedicated Control Channel).

[0154] As an example, the first type of SRB is used in CCCH (Common Control Channel).

[0155] As an example, the first type of SRB is used for at least training data reporting.

[0156] As an example, the first type of SRB is used for at least inference data reporting.

[0157] As an example, the first type of SRB is used to transmit data input to the AI / ML model.

[0158] As an example, the first type of SRB is used to transmit data output to the AI / ML model.

[0159] As an example, the first type of SRB is used to transmit configuration signaling for AI / ML models.

[0160] As an example, the first type of SRB is indicated by an SRB-Identity-v1900.

[0161] As an example, the first type of SRB is a low-priority SRB.

[0162] As an example, the low-priority SRB refers to the SRB whose latency requirement is below a threshold.

[0163] As an example, the reporting of low-priority data on the SRB is scheduled by the network.

[0164] As an example, the first type of SRB has a lower priority than at least SRB1.

[0165] As an example, the first type of SRB has the lowest priority among all SRBs.

[0166] As an example, the first type of SRB is AI / ML specific.

[0167] The above method introduces an AI / ML-specific SRB to avoid impacting existing protocols.

[0168] As an example, the first type of SRB is SRB4.

[0169] The above method extends the existing SRB4, avoids introducing new SRBs, and reduces the amount of standardization work.

[0170] As an example, the first type of SRB is SRBi, where i is greater than 5.

[0171] As an example, the first type SRB is SRBi, one candidate of i is 4, and another candidate of i is greater than 5.

[0172] As an example, i has only one candidate.

[0173] As one example, i has multiple candidates.

[0174] The above methods help improve configuration flexibility.

[0175] As an example, i is 6.

[0176] As an example, i is 7.

[0177] As an example, i is 8.

[0178] As an example, the second type of SRB is indicated by an SRB-Identity.

[0179] As an example, the second type of SRB is indicated by an SRB-Identity-v1700.

[0180] As an example, the second type of SRB is indicated by an SRB-Identity-v1800.

[0181] As an example, for the first type of SRB, the first logical channel is not defined with a default priority value; wherein the first type of SRB is SRBi, and i is greater than 5.

[0182] Given the low priority of AI / ML training and / or inference data, there is no need to define default parameters for logical channels, thus reducing standardization work.

[0183] As an example, for the first type of SRB, the first logical channel is defined with a default value for priority; wherein the default value is greater than 1, the first type of SRB is SRBi, and i is greater than 5.

[0184] The above method reduces configuration overhead by using the default parameters of the logical channel.

[0185] As an example, the default value is 16, which indicates the lowest priority.

[0186] As an example, the candidate priority bit rate of the first logical channel depends on the type of the first SRB in the following way: if the first SRB is a first type SRB, the candidate priority bit rate of the first logical channel includes a first value, which is finite; if the first SRB is a second type SRB, the candidate priority bit rate of the first logical channel only includes infinity; wherein the first type SRB and the second type SRB are different; the second type SRB is any one of a plurality of SRBs, which includes at least SRB1.

[0187] As one embodiment, the candidate priority bit rate of the first logical channel depends on the type of the first SRB as follows: if the first SRB is a first type SRB, the candidate priority bit rate of the first logical channel includes a first value and includes infinity, where the first value is finite; if the first SRB is a second type SRB, the candidate priority bit rate of the first logical channel only includes infinity; if the first SRB is a third type SRB, the candidate priority bit rate of the first logical channel only includes finite values; wherein the first type SRB, the second type SRB, and the third type SRB are all different from each other; the second type SRB is any one of a plurality of SRBs, the plurality of SRBs including at least SRB1.

[0188] As an example, the candidate priority bit rate of the first logical channel depends on the type of the first SRB as follows: if the first SRB is a first type SRB, the candidate priority bit rate of the first logical channel includes a first value and includes infinity, where the first value is finite; if the first SRB is a second type SRB, the candidate priority bit rate of the first logical channel only includes infinity; if the first SRB is a third type SRB, the candidate priority bit rate of the first logical channel only includes finite values; wherein the first type SRB, the second type SRB, and the third type SRB are all different from each other; the second type SRB is any one of a plurality of SRBs, and the plurality of SRBs includes at least SRB1.

[0189] As an example, the candidate for the priority bit rate of the first logical channel includes the first value, and the candidate for the priority bit rate of the first logical channel includes infinity.

[0190] As an example, the candidate of the priority bit rate of the first logical channel includes the first value, and the candidate of the priority bit rate of the first logical channel does not include infinity.

[0191] As one embodiment, data from the first logical channel has a higher priority than data from the second logical channel; wherein the second logical channel is configured for the DRB.

[0192] As an example, the statement "If the first SRB is a first type SRB, the candidate of the priority bit rate of the first logical channel includes a first value, the first value being finite" means that if the first SRB is the first type SRB, the priority bit rate of the first logical channel is not required to be set to infinity.

[0193] As an example, the statement "If the first SRB is a first type SRB, the candidate of the priority bit rate of the first logical channel includes a first value, the first value being finite" means that if the first SRB is the first type SRB, the priority bit rate of the first logical channel may not be set to infinitely large.

[0194] As an example, the statement "If the first SRB is a first type SRB, the candidate of the priority bit rate of the first logical channel includes a first value, the first value being finite" means that if the first SRB is the first type SRB, the priority bit rate of the first logical channel is not allowed to be set to infinity.

[0195] As an example, the first value is a non-negative integer, and the first value is not infinitely large.

[0196] As an example, the candidates for the first value include any one of 0, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, 8192, 16384, 32768, and 65536.

[0197] As an example, the candidates for the first value include at least one of 0, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, 8192, 16384, 32768, and 65536.

[0198] As an example, the candidates for the first value include 0.

[0199] As an example, the candidates for the first value do not include 0.

[0200] The above methods guarantee the performance of AI / ML.

[0201] As an example, the names of the first type of SRB and the second type of SRB are different.

[0202] As an example, the function of the first type of SRB is different from that of the second type of SRB.

[0203] As an example, the first type of SRB is for the Uu interface, and the second type of SRB is for the secondary link.

[0204] As an example, the first type of SRB is a secondary link, and the second type of SRB is a Uu interface.

[0205] As an example, the SRB-Identity of the first type of SRB is not equal to the SRB-Identity of the second type of SRB.

[0206] As an example, any one of the plurality of SRBs does not include the first type of SRB.

[0207] As an example, the plurality of SRBs includes at least two SRBs.

[0208] As an example, the plurality of SRBs includes at least SRB1 and SRB3.

[0209] As an example, the plurality of SRBs includes SRB1, SRB2, SRB3, SRB4, and SRB5; the first type of SRB is SRBi, and i is greater than 5.

[0210] As one embodiment, the plurality of SRBs includes SRB1, SRB2, SRB3, and SRB5; the first type of SRB is SRB4.

[0211] As an example, the plurality of SRBs includes SRB1, SRB2, SRB3, and SRB5; the first type of SRB is SRBi, one candidate of i is 4, and another candidate of i is greater than 5.

[0212] As an example, the plurality of SRBs includes any SRB other than the first type of SRB.

[0213] As an example, the first node receives an RRC message, the RRC message including PUCCH resources for the first logical channel for SR.

[0239] 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 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 includes the MAC (Medium Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the PDCP (Packet Data Convergence Protocol) sublayer 304. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. It also provides security through encrypted data packets and supports cross-area mobility. The RLC sublayer 303 provides segmentation and reassembly of upper-layer packets, retransmission of lost packets, and packet reordering to compensate for out-of-order reception due to HARQ (Hybrid Automatic Repeat Request). MAC sublayer 302 provides multiplexing between the logical and transport channels. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell.

[0245] Example 4

[0246] Example 4 shows schematic diagrams of a first communication device and a second communication device according to this application, as shown in the appendix. 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.

[0247] 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.

[0248] 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.

[0249] 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.

[0250] 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.

[0251] 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.

[0252] 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.

[0283] As an example, the resource allocation is directed to a UL grant.

[0284] As an example, the resource allocation is targeted at a PUSCH resource.

[0285] As an example, the resource allocation is part of the LCP process.

[0286] As one embodiment, the resource allocation includes allocating resources to at least one logical channel selected in the selection of logical channels.

[0287] As one embodiment, the at least one logical channel is a plurality of logical channels, and the at least one logical channel includes the first logical channel.

[0288] As an example, the at least one logical channel is the first logical channel.

[0289] As one embodiment, the resource allocation includes: allocating resources to the logical channel according to the following steps:

[0290] Step 1. Allocate resources to logical channels with Bj greater than 0 in descending order of logical channel priority. Specifically, if a logical channel's PBR is set to infinity, the MAC entity should allocate resources to all available data on the corresponding logical channel before satisfying the PBRs of lower-priority logical channels.

[0291] Step 2. Bj reduces the total size of the MAC SDU serving logical channel j.

[0292] Step 3. If resources remain, all logical channels selected in the logical channel selection process are served in descending order of absolute priority until either the data on the logical channel or the uplink grant is exhausted, whichever comes first. Logical channels configured with equal priority should receive the same service.

[0293] As an example, the first MAC PDU is assembled after the resource allocation.

[0294] As an example, after the resource allocation, at least one of the following is multiplexed in the first MAC PDU: at least one MAC SDU or at least one MAC CE.

[0295] As an example, after the resource allocation, at least one MAC SDU is multiplexed onto the first MACPDU, the at least one MAC SDU including at least a portion of the data on the first logical channel.

[0296] As an example, the first MAC PDU depends on the result of the resource allocation.

[0297] As an example, the first MAC PDU includes data on the MAC CE or logical channel on which resources are allocated in the resource allocation.

[0298] As an example, the at least part of the data on the first logical channel is all the data on the first logical channel.

[0299] As an example, the at least portion of the data on the first logical channel is at least one segment of the data on the first logical channel.

[0300] As an example, the size of the resource that the first logical channel is preferentially allocated in the resource allocation depends on the type of the first SRB.

[0301] As an example, the resource that is preferentially allocated refers to the resource allocated in step 1 of the resource allocation process.

[0302] As one embodiment, the size of the resource that the first logical channel is preferentially allocated in the resource allocation depends on the type of the first SRB, including:

[0303] If the first SRB is the first type of SRB, the size of the resource to which the first logical channel is preferentially allocated in the resource allocation depends on the Bj of the first logical channel.

[0304] If the first SRB is the second type of SRB, the size of the resource to which the first logical channel is preferentially allocated in the resource allocation does not depend on the Bj of the first logical channel.

[0305] As an example, if the first SRB is the first type of SRB, the priority bit rate of the first logical channel is the first value used to determine the size of the resource to which the first logical channel is preferentially allocated in the resource allocation, which depends on the Bj of the first logical channel.

[0306] As an example, if the first SRB is the second type of SRB, the priority bit rate of the first logical channel is infinitely large, which is used to determine the size of the resource to which the first logical channel is preferentially allocated in the resource allocation, and does not depend on the Bj of the first logical channel.

[0307] As an example, the size of the resource that is preferentially allocated to the first logical channel in the resource allocation depends on the Bj of the first logical channel, including: the size of the resource that is preferentially allocated to the data that can be transmitted on the first logical channel does not exceed Bj.

[0308] As one embodiment, the size of the resource that is preferentially allocated to the first logical channel in the resource allocation depends on the Bj of the first logical channel, including: if at least the Bj of the first logical channel is greater than 0, the size of the resource that is preferentially allocated to the data available for transmission on the first logical channel does not exceed Bj.

[0309] As a sub-implementation of the above embodiment, if Bj of the first logical channel is not greater than 0, resources are not preferentially allocated to data available for transmission on the first logical channel.

[0310] As one embodiment, the at least one logical channel includes a first logical channel and a third logical channel, wherein the third logical channel is configured to the DRB; the priority of the third logical channel is higher than the priority of the first logical channel.

[0311] As an example, the size of the resources that are preferentially allocated to the first logical channel in the resource allocation does not depend on the Bj of the first logical channel, which means that resources are preferentially allocated to all data available for transmission on the first logical channel before satisfying the PBR of a lower priority logical channel.

[0312] As an example, the size of the resources that are preferentially allocated to the first logical channel in the resource allocation does not depend on the Bj of the first logical channel, which means that regardless of whether the Bj of the first logical channel is greater than 0, resources are preferentially allocated to all data available for transmission on the first logical channel before satisfying the PBR of the lower priority logical channel.

[0313] Example 6

[0314] Example 6 illustrates a schematic diagram of the priority bit rate of a first logical channel according to an embodiment of the present application depending on whether there is a first type of data on the first logical channel.

[0315] In Example 6, if the first SRB is the first type of SRB, the priority bit rate of the first logical channel depends on whether there is first type of data on the first logical channel; the dependence of the priority bit rate of the first logical channel on whether there is first type of data on the first logical channel includes:

[0316] When the first type of data is on the first logical channel, the priority bit rate of the first logical channel is the first value;

[0317] When there is no data of the first type on the first logical channel, the priority bit rate of the first logical channel is infinitely large;

[0318] The candidates for the priority bit rate of the first logical channel include the first value and infinity.

[0319] As an example, if the first SRB is the first type of SRB and there is the first type of data on the first logical channel, the priority bit rate of the first logical channel is the first value; if the first SRB is the first type of SRB and there is no first type of data on the first logical channel, the priority bit rate of the first logical channel is infinite; if the first SRB is the second type of SRB, the priority bit rate of the first logical channel is infinite.

[0320] As an example, the first signaling includes a target field indicating the priority bit rate of the first logical channel; the target field is a prioritizedBitRate field.

[0321] As an example, the first signaling includes a target field that indicates the priority bit rate of the first logical channel; the target field is not the prioritizedBitRate field.

[0322] As a sub-implementation of the above embodiment, the prioritisedBitRate field is not configured in the first signaling.

[0323] As a sub-implementation of the above embodiment, the prioritisedBitRate field and the target field are not configured simultaneously in the first signaling.

[0324] As a sub-implementation of the above embodiment, the network ensures that the prioritizedBitRate field and the target field are not configured simultaneously in the first signaling.

[0325] As a sub-implementation of the above embodiment, the prioritisedBitRate field is configured in the first signaling.

[0326] As a sub-implementation of the above embodiments, the first signaling includes a target field and a prioritizedBitRate field, wherein the target field indicates the priority bit rate of the first logical channel; the target field is not a prioritizedBitRate field; and the prioritizedBitRate field indicates another priority bit rate of the first logical channel.

[0327] As a sub-implementation of the above embodiment, the prioritisedBitRate field indicates that another priority bit rate of the first logical channel is infinite.

[0328] As a sub-implementation of the above embodiment, the prioritisedBitRate field can only be set to infinity.

[0329] As an example, the first type of data includes at least one of training data, inference data, or reinforcement learning data.

[0330] As an example, the first type of data includes training and / or inference data and / or signaling.

[0331] As an example, the first type of data includes reinforcement learning data.

[0332] As an example, the first type of data includes training data.

[0334] As an example, the first type of data includes data input to the AI / ML model.

[0335] As an example, the first type of data includes data output to the AI / ML model.

[0336] As an example, the first type of data includes configuration signaling for AI / ML models.

[0337] As an example, the first type of data comes from the output of the AI / ML model applied by the first node.

[0338] As an example, the first type of data comes from the logs of the first node.

[0339] As an example, the first type of data comes from measurements taken at the first node.

[0340] As an example, the first type of data comes from the prediction of the first node.

[0341] As an example, the first type of data comes from the inference of the first node.

[0342] As one example, the first type of data comes from the storage of the first node.

[0343] As an example, the first type of data is stored in a UE variable.

[0344] As one example, the first type of data is stored in the hardware of the first node.

[0345] As an example, the first type of data is stored in the software of the first node.

[0346] As an example, the storage format of the first type of data on the first node is determined by the UE implementation.

[0347] Example 7

[0348] Example 7 illustrates a schematic diagram of a first logical channel not configured as an SR PUCCH according to an embodiment of the present application.

[0349] In Example 7, if the first SRB is the first type of SRB, the first logical channel is not configured as the PUCCH resource of the SR.

[0350] As an example, the first logical channel is not configured as an SR PUCCH resource dependent on the first logical channel and associated with the first type of SRB.

[0351] As an example, if the first SRB is a first type SRB, the first logical channel is not allowed to be configured as a PUCCH resource for the SR.

[0352] As an example, if the first SRB is a first type SRB, the network guarantees that the first logical channel will not be configured with PUCCH resources for an SR.

[0353] As an example, if the first SRB is a first type SRB, the first logical channel is not configured as a PUCCH resource for the SR based on the network implementation.

[0354] As a sub-implementation of the above embodiments, the network can also configure the first logical channel as SR PUCCH resources based on the implementation.

[0355] As an example, the first node does not expect the first logical channel to be configured as the PUCCH of SR.

[0356] As an example, RRC messages for the PUCCH resources of the first logical channel for SR are not received.

[0357] Example 8

[0359] In embodiment 8, the first signaling indicates the priority of the first logical channel; wherein, if the first SRB is the first type of SRB, the priority of the first logical channel is lower than the priority of any one of the plurality of SRBs.

[0360] As an example, the first signaling includes a priority, which indicates the value of the priority of the first logical channel.

[0361] As an example, the first signaling includes a field whose name includes priority, the field whose name includes priority indicating the value of the priority of the first logical channel.

[0362] As one embodiment, the first signaling indicates the value of the priority of the first logical channel; the larger the value of the priority of the first logical channel, the lower the priority of the first logical channel; the smaller the value of the priority of the first logical channel, the higher the priority of the first logical channel.

[0363] As an example, the network guarantees that the priority of the first logical channel is lower than the priority of any one of the plurality of SRBs.

[0364] As an example, the priority of the first logical channel is not allowed to be higher than the priority of any one of the plurality of SRBs.

[0370] As an example, the first field is set to one of harqModeA, harqModeB, and harqModeC.

[0371] The above method is beneficial to improving the configuration flexibility of the first type of SRB.

[0372] As an example, the first type of SRB is SRBi, where i is greater than 5.

[0373] The above method is beneficial for adaptively adjusting the reliability of the transmission of the first type of SRB.

[0374] As an example, the first type of SRB is SRB4.

[0375] As one embodiment, the first signaling includes the first field, and the first signaling does not include the second field.

[0377] Example 10 illustrates a schematic diagram of a second field of a first signaling according to an embodiment of the present application indicating that segmentation of an RRC message on a first type SRB is enabled, as shown in the attached diagram. Figure 10 As shown.

[0378] In embodiment 10, the first signaling includes a second field indicating that segmentation of RRC messages on the first type SRB is enabled; wherein, the first SRB is the first type SRB.

[0388] As a sub-example of the above embodiments, the candidates for the reportingSRB-r18 domain include srb4 and srbi.

[0389] As one embodiment, the first signaling includes the first domain and the second domain.

[0390] As one embodiment, the first signaling includes the second field, and the first signaling does not include the first field.

[0391] Example 11

[0392] Example 11 illustrates a schematic diagram of the priority order of data from a first logical channel according to an embodiment of this application, as shown in the attached diagram. Figure 11 As shown.

[0393] In embodiment 11, data from the first logical channel is prioritized in a lower order than data from the second logical channel; wherein the first SRB is the first type of SRB, and the second logical channel is configured for the DRB.

[0394] As an example, the fact that data from the first logical channel is prioritized less than data from the second logical channel means that the priority order of the first logical channel and the second logical channel is as follows:

[0395] - The data from the second logical channel;

[0396] - The data from the first logical channel.

[0397] As an example, the data from the first logical channel takes precedence over the Recommended bitrate MAC CE.

[0398] As an example, the Recommended bit rate MAC CE takes precedence over the data from the first logical channel.

[0399] As an example, any MAC CE takes precedence over the data from the first logical channel.

[0400] As an example, any MAC CE other than the BSR MAC CE for filling takes precedence over the data from the first logical channel; the data from the first logical channel takes precedence over the BSR MAC CE for filling.

[0401] As an example, the fact that data from the first logical channel is prioritized in a lower order than data from the second logical channel means that the priority of the first logical channel is lower than the priority of the second logical channel.

[0402] As a sub-implementation of the above embodiments, the lower priority of the first logical channel compared to the second logical channel is configured by the network.

[0403] As a sub-implementation of the above embodiments, the priority value of the first logical channel is greater than the priority value of the second logical channel.

[0404] As a sub-implementation of the above embodiments, a priority field in the first signaling indicates the priority value of the first logical channel; and a priority field in a LogicalChannelConfig IE for the second logical channel indicates the priority value of the second logical channel.

[0405] As a sub-implementation of the above embodiments, the lower priority of the first logical channel than that of the second logical channel is specified by the protocol.

[0406] As a sub-implementation of the above embodiments, the lower priority of the first logical channel compared to the second logical channel is based on network implementation.

[0407] As a sub-implementation of the above embodiments, the first node considers the priority of the first logical channel to be lower than the priority of the second logical channel.

[0408] As a sub-implementation of the above embodiments, the first node may consider that the priority of the first logical channel is lower than the priority of the second logical channel.

[0409] As a sub-implementation of the above embodiments, the assumption is made.

[0410] As a sub-implementation of the above embodiments, the term "considered" is used to refer to something that is considered as such.

[0411] As one example, the order in which data from the first logical channel is prioritized is lower than the order in which data from the second logical channel is prioritized depends on at least the first SRB being the first type of SRB.

[0412] As an example, when at least the first SRB is the first type of SRB, the data from the first logical channel is prioritized in a lower order than the data from the second logical channel.

[0413] As an example, when the first SRB is the first type of SRB, the data from the first logical channel is prioritized in a lower order than the data from the second logical channel.

[0414] As one example, the priority order of data from the first logical channel is lower than that of data from the second logical channel, depending on at least the first SRB being the first type of SRB and the first type of data being on the first logical channel.

[0415] As an example, when the first SRB is the first type of SRB and the first type of data is on the first logical channel, the data from the first logical channel is given priority in a lower order than the data from the second logical channel.

[0416] As an example, if the first SRB is not the first type of SRB or there is no first type of data on the first logical channel, the data from the first logical channel is given priority over the data from the second logical channel.

[0417] As an example, if the first SRB is not the first type of SRB or there is no first type of data on the first logical channel, the order in which data from the first logical channel is prioritized and the order in which data from the second logical channel is prioritized are determined by the first node itself.

[0418] As an example, if the first SRB is not the first type of SRB or there is no first type of data on the first logical channel, the order in which data from the first logical channel is prioritized and the order in which data from the second logical channel is prioritized depend on the UE implementation.

[0419] As an example, if the first SRB is not the first type of SRB or there is no first type of data on the first logical channel, the order in which data from the first logical channel is prioritized and the order in which data from the second logical channel is prioritized are not specified by the protocol.

[0420] As an example, the first type of data refers to Example 6, which will not be repeated here.

In the appendix Figure 13 In the second node, the processing device 1300 includes a second transmitter 1301 and a second receiver 1302.

[0441] The second transmitter 1301 transmits a first signaling message; wherein the first signaling message indicates the priority bit rate of the first logical channel, and the first logical channel is associated with the first SRB;

[0442] In Example 13, the candidate priority bit rate of the first logical channel is a value in kilobytes per second, and the candidate priority bit rate of the first logical channel depends on the type of the first SRB; the dependency of the candidate priority bit rate of the first logical channel on the type of the first SRB includes:

[0537] Example 16

[0538] Example 16 illustrates a schematic diagram of intelligent function deployment in a RAN (Radio Access Network) domain according to an embodiment of this application; as shown in the appendix. Figure 16 As shown. In Example 16, the gNB can be replaced with, for example, an eNB, or a network device such as a 6G base station.

[0539] Intelligent functions in the RAN domain include training (also known as ML training, AI training, or AI / ML training), testing (also known as ML testing, AI testing, or AI / ML testing), and inference (also known as ML inference, AI inference, or AI / ML inference), among others. Training, testing, and inference functions can be deployed independently or co-located. Deployment of intelligent functions can be achieved through software, such as downloading and / or running executable files; or through a combination of software and hardware, such as accelerating specific computing units through hardware to improve processing speed or save power.

[0540] Training functions can be deployed in a cross-domain management system or a domain-specific management system; the domain-specific management system is used to manage the RAN domain or the CN (Core Network) domain. For example, training functions for MDA (Management Data Analytics) can be deployed in MDAF (MDA Function); training functions for network data analytics can be deployed in NWDAF (Network Data Analytics Function), meaning the training function is MTLF (Model Training Logical Function).

[0541] Similarly, inference functions can be deployed in cross-domain management systems or domain-specific management systems; for example, the inference function is an MDAF, or the inference function is an AnLF (Analytics logical function) located in an NWDAF.

[0542] Similarly, testing functionality can also be deployed in cross-domain management systems or domain-specific management systems.

[0543] In embodiment 16, the training function 1702 of the RAN domain is located in the management function 1703 of the RAN domain; while the inference function is located in the base station, that is, inference function 1704 is located in gNB 1705, and inference function 1706 is located in gNB 1707. Figure 16 The ellipsis in the text indicates other gNBs that include other reasoning functions and are not shown.

[0544] Appendix Figure 16 In this context, the management of inference functions for multiple base stations is handled by the RAN domain management function 1703, which interacts with the RAN domain MnS (MangementService) consumer / cross-domain management 1701 (as shown in the attached diagram). Figure 16 (As shown by the dashed arrow 1708 in the image).

[0545] Optionally, the management of inference functions can also be completed by the base station itself, that is, each base station can independently interact with the RAN domain MnS consumer / cross-domain management 1701.

[0546] It should be noted that Embodiment 16 is merely a non-limiting implementation method; optionally, the training function of the RAN domain may also be deployed at the base station; or optionally, some base stations may deploy both the inference function and the training function of the RAN domain, while some base stations may only deploy the inference function.

[0559] The UE intelligent function 1804 is deployed in the first node of this application. The UE intelligent function 1804 includes an inference function 1806. The inference function 1806 uses an AI / ML model (also known as an AI model, or an ML model, or an AI / ML model) for inference.
