[0101] It should be noted that Figures 2 to 4 are merely examples of the embodiments of the present application and do not limit the specific solutions provided in the embodiments of the present application.

[0102] Below, in combination with the accompanying drawings, a data transmission configuration method, apparatus, terminal, device and core network element provided by the embodiment of the present application are described in detail through some embodiments and their application scenarios.

[0103] Please refer to FIG5 , which is a flowchart of a data transmission configuration method provided in an embodiment of the present application. As shown in FIG5 , the method includes the following steps:

[0104] Step 501: The terminal receives target information sent by the network side, where the target information includes at least one of the following: permission information for permitting layer 2 operations and configuration information for layer 2 operations;

[0105] The layer 2 operations include:

[0106] Mapping the first data content in the data content set to the first RB, and mapping the second data content in the data content set to the second RB; or,

[0107] The first data content in the data content set is mapped to the first queue of the third RB, and the second data content in the data content set is mapped to the second queue of the third RB or the second data content in the data content set is inserted into the first queue for processing.

[0108] The above-mentioned data content set may be a QoS flow set, a data packet set or a data packet group set, etc., and the type of these data contents may be signaling or data.

[0109] For example: the above-mentioned data content set can be a collection of QoS flows, data packets or data packet groups with the same or similar QoS, or the above-mentioned data content set can be a collection of QoS flows, data packets or data packet groups with the same or similar transmission requirements, or the above-mentioned data content set can be a collection of QoS flows, data packets or data packet groups of the same or similar services, or the above-mentioned data content set can be a collection of QoS flows, data packets or data packet groups of the same IP quintuple.

[0110] The second data content includes data content with special requirements, and may also include data content associated with data content with special requirements, such as data content QoS flows, data packet sets, or data packet groups with special requirements. The special requirements may be indicated by the network, agreed upon by the protocol, or determined by the terminal itself. The special requirements may also be referred to as target requirements or specific requirements. For example, the special requirements may include at least one of the following:

[0111] Reliability requirements, latency requirements, importance requirements, and priority requirements.

[0112] Among them, the above-mentioned reliability requirement means that the reliability of the above-mentioned second data content is higher than that of other data content, the above-mentioned delay requirement means that the delay requirement of the above-mentioned second data content is higher than that of other data content, the above-mentioned importance requirement means that the above-mentioned second data content is more important than other data content, and the above-mentioned priority requirement means that the above-mentioned second data content has a higher priority than other data content.

[0113] For example, the second data content may include at least one of the following:

[0114] Special data packets, such as Transmission Control Protocol (TCP) acknowledgment (ACK) or TCP feedback, generally have higher reliability and latency requirements;

[0115] Special data packet combinations, such as a group of extended reality (XR) service packets, which contain some special frames (such as header frames because they contain important decoding information), also have higher reliability requirements. The entire packet combination has a unified latency requirement.

[0116] The first data content may be data content in the data content set excluding the second data content.

[0117] The first RB may be a signaling radio bearer (SRB) or a data radio bearer (DRB), the second RB may be an SRB or a DRB, and the third RB may be an SRB or a DRB.

[0118] In addition, the second RB may refer to one or more RBs, that is, one or more RBs may be created for the second data content.

[0119] The second queue may be one or more queues, that is, one or more queues may be created for the second data content.

[0120] The above-mentioned inserting the second data content in the data content set into the first queue for processing can be understood as that the second data content does not need to follow the first-in-first-out principle when inserting into the first queue. The second data content is inserted into the first queue in a queue-jumping manner. For example, according to the first-in-first-out principle, the second data content should be at the first position of the first queue. In the above-mentioned layer 2 operation, the second data content is inserted into the second position of the first queue, and the second position is before the first position, such as inserting the second data content into the earliest position of the first queue.

[0121] The above-mentioned target information includes at least one of the permission information for permitting layer 2 operations and the configuration information for layer 2 operations. It can be understood that the above-mentioned target information includes the permission information for permitting layer 2 operations, or the above-mentioned target information includes the configuration information for layer 2 operations, or the above-mentioned target information includes the permission information for permitting layer 2 operations and the configuration information for layer 2 operations.

[0122] The permission information is used to permit the terminal to perform the layer 2 operation. It should be noted that, in the embodiment of the present application, the target information is not limited to include the permission information. For example, in some implementations, it may be assumed that the terminal can perform the layer 2 operation.

[0123] The configuration information of the above-mentioned layer 2 operation is used to configure the relevant configuration of the above-mentioned layer 2, such as the number of queues, the number of RBs, the processing method of the second data content, etc. It should be noted that in the embodiments of the present application, the above-mentioned target information is not limited to include the above-mentioned configuration information. For example, in some embodiments, the terminal can pre-configure or agree on the configuration of the above-mentioned layer 2 operation.

[0124] In an embodiment of the present application, the above steps can be used to map the data contents in the same data content set to different RBs or queues respectively, or insert the second data content in the data content set into the first queue for processing, thereby improving the flexibility of data transmission processing.

[0125] Furthermore, since the secondary data content is mapped to a separate RB or queue for processing, such as processing of a separate RB or sub-queue based on QoS or transmission requirements, QoS and transmission requirements can be better met while ensuring fairness. Furthermore, it can support separate and efficient processing of the secondary data content, ensuring better transmission of terminal data, thus significantly improving user QoS and user experience while ensuring data transmission efficiency.

[0126] In an embodiment of the present application, the above-mentioned terminal can perform the above-mentioned layer 2 operation to send the above-mentioned data content set, or the above-mentioned layer 2 operation can be performed by the communication counterpart (such as a network side device), and the terminal performs the corresponding reception of the layer 2 operation. It can be seen that whether the terminal acts as a sending end or a receiving end, the data transmission performance of the terminal can be improved.

[0127] The above-mentioned layer 2 operation is a special operation newly defined in the embodiment of the present application. Therefore, the above-mentioned layer 2 operation can also be called a special layer 2 operation or layer 2 processing.

[0128] As an optional implementation, the permission information may explicitly or implicitly permit the layer 2 operation.

[0129] For example: the network side explicitly permits the terminal to perform the above-mentioned Layer 2 operations (such as some special Layer 2 processing), wherein the Layer 2 configuration can remain unchanged, such as the mapping of QoS flow to RB still adopts the configuration method and rules agreed upon by the protocol, and the Layer 2 parameters can also maintain the mechanism defined by the protocol; when the terminal receives the above-mentioned permission information, it maps the QoS flow to the RB according to the configuration, and when processing specific data at Layer 2, it performs independent processing according to the transmission requirements of different data packets or different groups of data packets. In addition, for the processing of different data packets or different groups of data packets, the network side can also have some additional configurations, such as: configuring the maximum number of sub-queues, and some special parameters for sub-queue processing, etc.; if there is no additional configuration, it can be based on the terminal's own capabilities and implementation.

[0130] As an optional implementation manner, the first RB is a primary RB, and the second RB is a secondary RB; or,

[0131] The first queue is a main queue, and the second queue is a sub-queue or an auxiliary queue.

[0132] The above-mentioned primary RB can be understood as the main RB for transmitting the above-mentioned data content set, and the above-mentioned secondary RB can be understood as the secondary RB of the primary RB.

[0133] The above-mentioned main queue can be understood as the main queue for transmitting the above-mentioned data content set or the main queue of the above-mentioned third RB, and the above-mentioned sub-queue or auxiliary queue can be understood as the sub-queue or auxiliary queue of the main queue.

[0134] Since the main RB and the main queue are included, it is possible to retain the original configuration when performing the above-mentioned layer 2 operations, thereby reducing the complexity of the layer 2 operations.

[0135] In some embodiments, the first RB and the second RB may also be RBs of the same type or the same level, and the first queue and the second queue may also be queues of the same type or the same level, that is, the second RB is not limited to being an auxiliary RB, and the second queue is not limited to being a sub-queue or auxiliary queue.

[0136] As an optional implementation manner, the second data content includes at least one of the following:

[0137] QoS flows, packets, and packet groups.

[0138] The aforementioned QoS flows, data packets, and data packet groups may be QoS flows, data packets, and data packet groups with special requirements, such as those with special reliability requirements, special latency requirements, or special priority requirements, such as those for transmitting TCP ACKs or TCP feedback or a group of XR service packets.

[0139] In this embodiment, transmission processing can be performed at the granularity of QoS flow, data packet or data packet group to improve the flexibility of transmission, and efficient processing can also be achieved while ensuring QoS protection for these QoS flows, data packets and data packet groups.

[0140] As an optional implementation manner, the first data content and the second data content belong to the same QoS flow.

[0141] In this implementation, different data contents of the same QoS flow can be mapped to different RBs or queues for separate processing. This supports a separate and more efficient processing method for the second data content, ensures better data transmission effects, and greatly improves the ultimate QoS protection and experience on the basis of ensuring data transmission efficiency.

[0142] It should be noted that, in some implementations, the first data content and the second data content may also belong to different QoS flows, for example, the first data content is mapped to one QoS flow, and the second data content is mapped to another QoS flow.

[0143] Specifically, as shown in Figure 6 or Figure 7, the first data content is represented as ordinary data, and the second data content is represented as data packet / group 1, data packet / group 2, or data packet / group 3. It can be seen that the first data content and the second data content can be mapped to the same QoS flow or to different QoS flows.

[0144] As an optional implementation manner, the configuration information includes at least one of the following:

[0145] Number of queues;

[0146] Number of RBs;

[0147] processing information of a first process, where the first process is processing performed on the second queue by mapping the second data content;

[0148] Processing information of a second process, where the second process is processing performed on the second RB by mapping the second data content;

[0149] Description information of the second data content;

[0150] Reclaim information of the second RB, where the reclaim information is used to indicate that the second RB is reclaimed after the second data content is transmitted;

[0151] Reclaim information of the second queue, the reclaim information being used to indicate that the second queue is reclaimed after the second data content is transmitted;

[0152] A mapping relationship between the second data content and the quality of service QoS flow;

[0153] A dynamic mapping relationship between the second RB and the QoS flow;

[0154] A dynamic mapping relationship between the second queue and the QoS flow.

[0155] The number of queues mentioned above may be the number of second queues, such as the number of sub-queues.

[0156] The number of RBs mentioned above may be the number of second RBs, such as the number of secondary RBs.

[0157] The processing information of the first processing is used to indicate the processing mode of the second data content mapped to the second queue, such as priority processing, processing for temporarily improving reliability, and other special processing.

[0158] The processing information of the second processing is used to indicate the processing mode of the second data content mapped to the second RB, such as priority processing, processing for temporarily improving reliability, and other special processing.

[0159] The description information of the second data content is used to describe the second data content to indicate which data content is the second data content.

[0160] The above-mentioned second RB reclaiming information is used to indicate that the second RB is reclaimed after the second data content is transmitted, which can save RB overhead, and can be specifically reclaimed dynamically.

[0161] The above-mentioned reclaiming information of the second queue is used to indicate that the second queue is reclaimed after the second data content is transmitted, which can save queue overhead and can be specifically recycled dynamically.

[0162] The mapping relationship between the second data content and the QoS flow can be a mapping relationship indicated by the core network. As shown in Figure 6 or Figure 7, the first data content and the second data content can be mapped to the same QoS flow, or mapped to different QoS flows. The mapping relationship between the second data content and the QoS flow is specifically a dynamic mapping relationship, that is, the dynamic mapping relationship between the second data content and the QoS flow can be dynamically changed to further improve the flexibility of data transmission.

[0163] The dynamic mapping relationship between the above-mentioned second RB and the QoS flow indicates that the mapping relationship between the above-mentioned second RB and the QoS flow is dynamically changeable. For example, the QoS flow mapped to the second RB is dynamically changeable, and can be dynamically adjusted according to business requirements, data content requirements, etc., so as to further improve the flexibility of data transmission.

[0164] The dynamic mapping relationship between the above-mentioned second queue and the QoS flow indicates that the mapping relationship between the above-mentioned second queue and the QoS flow is dynamically changeable. For example, the QoS flow mapped to the second queue is dynamically changeable, and can be dynamically adjusted according to business requirements, data content requirements, etc., so as to further improve the flexibility of data transmission.

[0165] In the above implementation manner, the flexibility of data transmission can be further improved by configuring at least one of the above items.

[0166] It should be noted that, in some embodiments, some of the above-mentioned at least one item of the above-mentioned configuration information configuration may also be agreed upon by protocol or pre-configured, and there is no limitation on this, such as the number of queues, the number of RBs, the processing information of the first processing, the processing information of the second processing, the description information of the second data content, the retrieval information of the second RB, the retrieval information of the second queue, and the above-mentioned mapping relationship may be pre-configured or agreed upon by protocol, and there is no limitation on this in the embodiments of the present application.

[0167] Optionally, the processing information of the first process is used to indicate at least one of the following:

[0168] The second data content is processed with priority, the second data content is processed according to the data packet group, and the second data content is processed with improved transmission reliability; or

[0169] The processing information of the second process is used to indicate at least one of the following:

[0170] The second data content is processed with priority, the second data content is processed according to the data packet group, and the second data content is processed to improve transmission reliability.

[0171] The first process and the second process may be the same or different, which is not limited.

[0172] The above-mentioned second data content priority processing can achieve the second data content priority processing, thereby reducing the transmission delay of the second data content.

[0173] The second data content may be processed based on the data packet group. For example, data packets in the same data packet group may be processed uniformly, with one data packet group processed before another. Processing the second data content based on the data packet group ensures transmission reliability of the data packets within the same data packet group.

[0174] The above-mentioned second data content transmission reliability improvement processing can be an instruction to the lower layer to temporarily improve the transmission reliability of the second data content, for example: sacrificing some transmission efficiency in exchange for high reliability, using more reliable coding or transmission parameters, more HARQ retransmission times, HARQ retransmission (HARQ repetition), etc., such as improving the reliability requirements of important packets. This type of data (such as special frames in XR data, these frames have important header data for encoding and decoding), if lost or delayed, will cause the entire data frame set to fail to decode and be discarded. In this way, the overall reliability of data transmission can be improved by improving the transmission reliability processing of the second data content.

[0175] In some embodiments, when the network side configures the above-mentioned configuration information (i.e., provides the configuration related to the above-mentioned layer 2 operation), it configures a mapping to multiple RBs for a QoS flow, wherein one RB is used as the main mapping (i.e., the above-mentioned first RB), and most of the data of the QoS flow is mapped to the first RB for normal operations. There are also one or more auxiliary RBs (i.e., the above-mentioned second RB) as the carriers of the second data content (such as special data packets or data packet groups), and some special operations different from the main RB are taken to better meet the QoS and processing requirements of these data packets; the mapping and occupancy of the auxiliary RB can be temporary. When the second data content is completed, the auxiliary RB is reclaimed and waits for the next use.

[0176] As an optional implementation manner, the terminal determines the second data content based on at least one of the following:

[0177] The QoS flow ID of the second data content, the packet header information of the second data content, the PDU set ID of the second data content, the delay parameter of the second data content, and the characteristic information of the set deletion packet of the second data content.

[0178] The determining of the second data content is before performing the layer 2 operation, identifying the second data content based on the at least one item and performing the layer 2 operation.

[0179] The header information of the second data content may be a specific special field in the header, and the attributes of the specific field are read out to identify the second data content.

[0180] The above-mentioned determination of the second data content based on the above-mentioned at least one item can be carried out by the terminal in advance obtaining a determination rule for determining the second data content based on the above-mentioned at least one item, or the above-mentioned at least one item of the second data content obtained in advance by the terminal, so that the second data content can be accurately determined through the above-mentioned at least one item.

[0181] As an optional implementation, the method further includes:

[0182] The terminal creates a mapping of the QoS flow to the RB based on the target information, wherein the mapping of the QoS flow to the RB includes:

[0183] a mapping of a first QoS flow to the first RB, and a mapping of a second QoS flow to the second RB, wherein the first QoS flow includes the first data content, and the second QoS flow includes the second data content; or

[0184] The mapping of the QoS flow to the third RB, in the mapping of the QoS flow to the third RB, the third QoS flow mapped by the first queue includes the first data content, and the fourth QoS flow mapped by the second queue includes the second data content.

[0185] The mapping of the QoS flow to the RB may be instructed by a network-side device, such as a radio access network device.

[0186] The above-mentioned first QoS flow and second QoS flow can be the same QoS flow, such as the data content in one QoS flow is mapped to the first RB and the second RB respectively, or the above-mentioned first QoS flow and second QoS flow can be different QoS flows, such as the data content in different QoS flows is mapped to the first RB and the second RB respectively.

[0187] The above-mentioned third QoS flow and fourth QoS flow can be the same QoS flow, such as the data content in one QoS flow is mapped to the first queue and the second queue respectively, or the above-mentioned first QoS flow and second QoS flow can be different QoS flows, such as the data content in different QoS flows is mapped to the first queue and the second queue respectively.

[0188] In addition, the first QoS flow, the second QoS flow, the third QoS flow and the fourth QoS flow may all be one or more QoS flows.

[0189] The mapping of the first QoS flow to the first RB, the mapping of the second QoS flow to the second RB, or the mapping of the QoS flow to the third RB can be dynamic mapping, that is, the mapping relationship between the QoS flow and the RB can be dynamically adjusted. For example: in the mapping of QoS flow to RB, if the second data content (such as a data packet with special attributes) and the first data content (such as ordinary data) adopt the same QoS flow, then the QoS flow will be mapped to the primary RB and N secondary RBs at the same time, where N is in the range of [1, the maximum number of secondary RBs], or if the second data content and the first data content adopt different QoS flows, then the QoS flow of the first data content can be mapped to the primary RB, and the mapping relationship between the remaining QoS flows and the secondary RBs can be completely dynamic, that is, each QoS flow can be mapped to any one of all the secondary RBs, or different QoS flows can be grouped to limit the mapping of certain secondary RBs.

[0190] The creation of the QoS flow to RB mapping based on the target information may be creation of the QoS flow to RB mapping based on the configuration information, or may be creation of the QoS flow to RB mapping triggered by the permission information.

[0191] In addition, the number of the second RBs or second queues can be established with reference to the maximum number of parallel data packets / groups.

[0192] The terminal creates a mapping of QoS flows to RBs based on the target information, which can support dynamic mapping of QoS flows to RBs and further improve the reliability of data transmission.

[0193] Optionally, at least one QoS flow in the second QoS flow is mapped to the same second RB, or data content of the same QoS flow in the second QoS flow is mapped to at least one second RB; or

[0194] At least one QoS flow in the fourth QoS flows is mapped to the same second queue, or data content of the same QoS flow in the fourth QoS flows is mapped to at least one second queue.

[0195] Among them, at least one QoS flow in the above-mentioned second QoS flow is mapped to the same second RB. In this case, when the second QoS flow is one QoS flow, this one QoS flow is mapped to one second BR; when the second QoS flow is multiple QoS flows, these multiple QoS flows are mapped to one second BR.

[0196] The data content of the same QoS flow in the above-mentioned second QoS flow is mapped to at least one second RB. In the case where the second QoS flow is one QoS flow, this one QoS flow is mapped to one or more second BRs. In the case where the second QoS flow is multiple QoS flows, each QoS flow in these multiple QoS flows is mapped to one or more second BRs, and the QoS flows mapped to each second RB can be the same or different.

[0197] Among them, at least one QoS flow in the above-mentioned fourth QoS flow is mapped to the same second queue. In this case, when the fourth QoS flow is one QoS flow, this one QoS flow is mapped to one second queue; when the fourth QoS flow is multiple QoS flows, these multiple QoS flows are mapped to one second queue.

[0198] The data content of the same QoS flow in the above-mentioned fourth QoS flow is mapped to at least one second queue. In the case that the fourth QoS flow is one QoS flow, this one QoS flow is mapped to one or more second queues. In the case that the fourth QoS flow is multiple QoS flows, each QoS flow in these multiple QoS flows is mapped to one or more second queues, and the QoS flows mapped to each second queue can be the same or different.

[0199] In this implementation, at least one QoS flow can be mapped to the same second RB, and the data content of the same QoS flow can also be mapped to one or more second RBs, further improving the flexibility of data transmission.

[0200] In this implementation, at least one QoS flow can be mapped to the same second queue, and the data content of the QoS flow can also be mapped to one or more second queues, further improving the flexibility of data transmission.

[0201] As an optional implementation manner, when the terminal is a transmitting end, the method further includes:

[0202] The terminal performs a sending process, wherein the sending process satisfies one of the following:

[0203] In a case where the second data content includes feedback-related data content: the second data content and third data content are processed in the second RB or the second queue, or the third data content is first processed in the first RB or the first queue, and then the second data content is processed in the second RB or the second queue; wherein the third data content is data content in the data content set that is associated with the feedback-related data content;

[0204] Data content belonging to the same PDU set as the second data content is processed in the second RB or the second queue;

[0205] The first RB and the second RB jointly calculate a guaranteed bit rate;

[0206] The first queue and the second queue jointly calculate a guaranteed bit rate;

[0207] The second RB is processed first;

[0208] The second queue is processed first;

[0209] Improving the transmission reliability of the second data content;

[0210] In the case where the second data content includes a data packet group, processing the data packets in the data packet group in a unified manner;

[0211] In the case where the second data content includes a data packet group, the data packets in the data packet group carry identity tag information of the data packets in the data packet group;

[0212] In the case where the second data content includes a data packet group, when the second RB completes transmitting one data packet group, resetting the transmission variable corresponding to the second RB;

[0213] The data packets in the second data content carry a queue identifier of the second queue, where the queue identifier is used to indicate that the data packets in the second queue can independently perform layer 2 related operations;

[0214] The data packets in the second data content carry a complete count value.

[0215] The feedback-related data content may be a data packet for feedback, which also carries data or a sequence number in this direction, such as a TCP ACK / feedback packet, which carries data and a sequence number in this direction.

[0216] The data content associated with the feedback-related data content may be the data content of the same IP quintuple or the same TCP stream as the feedback-related data content.

[0217] In this way, the second and third data contents are processed in the second RB or second queue, or the third data contents are processed in the first RB or first queue first, followed by the second data contents in the second RB or second queue. This avoids the following situation: prioritizing only feedback-related data contents, which would cause sequence number (SN) gaps or packet loss in this direction, thereby causing adverse operations such as TCP slow start and reducing the rate in this direction. This improves the data transmission rate.

[0218] For example: when giving priority to TCP ACK / feedback packets or inserting them into independent auxiliary RBs, you can consider inserting the data of the same IP five-tuple or the same TCP stream that has not been transmitted or confirmed in the queue into the independent auxiliary RB in sequence for priority processing, or wait for the data transmission of the same IP five-tuple or the same TCP stream that has not been transmitted or confirmed in the queue to be successful before giving priority to the TCP ACK / feedback packets in the independent RB.

[0219] The above-mentioned data content belonging to the same PDU set (PDU Set) as the second data content is processed in the second RB or the second queue, which can be mapping the data content belonging to the same PDU set to the same second RB or second queue, and one second RB or second queue can serve one PDU Set and then insert another new PDU set for further processing, which is equivalent to dynamic sequential use to improve the reliability of PDU set transmission.

[0220] The above-mentioned first RB and the second RB jointly calculate the guaranteed bit rate, and the first RB and the second RB can calculate the guaranteed bit rate together, that is, when performing logical channel priority (LCP) processing, the bit rate and token bucket and other rules are guaranteed, and a group of associated RBs (including the first RB and the second RB) can be summed up. In this way, by jointly calculating the guaranteed bit rate, the bit rate and token bucket and other rules can be guaranteed to improve the reliability of data transmission.

[0221] The above-mentioned first queue and the second queue jointly calculate the guaranteed bit rate. The first queue and the second queue belong to the same RB, and the guaranteed bit rate is calculated together. That is, when performing LCP processing, the guaranteed bit rate and token bucket and other rules can be added together for the same RB (including the first queue and the second queue). In this way, by jointly calculating the guaranteed bit rate, the bit rate and token bucket and other rules can be guaranteed to improve the reliability of data transmission.

[0222] The above-mentioned second RB or second queue priority processing can be used when the second data content has additional latency requirements and needs to be processed first, such as a TCP ACK / feedback packet. In the absence of other earlier TCP packets in this direction, this important data packet is mapped to a second RB or second queue, and the second RB or second queue can have at least a higher priority than the first RB or first queue. That is, the TCP ACK / feedback packet can not follow the first-come-first-out rule in traditional queues, but can be transmitted in advance to reach the other end as soon as possible, update the other end's confirmation status and send status, release and increase the send window, and thus greatly improve the transmission rate in the reverse direction. The processing priority of TCP ACK / feedback packets and the priority processing of data in other subqueues can adopt a simple first-come-first-served principle, that is, equal priority, or data that is about to expire can be given higher priority, even with a configured priority, or the terminal can implement the priority principle for sequential processing. The above-mentioned second RB or second queue priority processing can reduce the latency of the second data content and improve service performance.

[0223] The above-mentioned improvement in the transmission reliability of the second data content can be that if the second data content requires higher reliability requirements, an instruction can be given to the lower layer to temporarily improve the transmission reliability, such as sacrificing some transmission efficiency in exchange for high reliability, using more reliable coding or transmission parameters, more HARQ retransmission times, HARQ repetition (HARQ repetition), etc., to improve the reliability requirements of important packets. If this type of data (such as special frames in XR data, these frames have important header data for encoding and decoding) is lost or delayed, it will cause the entire data frame set to fail to be decoded and be discarded, etc., so that the overall reliability and efficiency of the data can be improved by improving the transmission reliability of the second data content.

[0224] The aforementioned unified processing of packets within the packet group can mean that after a packet group is inserted into a second RB or a second queue, it will be treated uniformly to improve the transmission reliability of the packet group. For example, the maximum discard delay for the packet group will be calculated based on the time of the earliest inserted packet. Once the timeout expires, the entire packet group becomes ineffective and can be deleted, and resources that have already been successfully transmitted will be wasted. The packet groups within the second data content can also be subject to certain fairness principles, just like the data within the first RB. For example, a first-come, first-out (FCF) sorting method can be used to sort packets within the packet group. When processing is possible, the entire packet group is transmitted sequentially, followed by the transmission of other data. The transmission order between the packet group and other packet groups can also be based on fairness principles. For example, a first-come, first-out (FCF) sorting method can be used to sort packets within the packet group based on the arrival time of the first packet within the packet group. Each packet group is transmitted sequentially. Once the packet group's turn comes, all data within the entire packet group is transmitted sequentially, and the transmission of the next packet group begins. Additionally, based on the above, the priority of the data packet group that is about to time out or the data packet group with less delay can be appropriately increased to a certain extent so that all data packets can be transmitted before timeout.

[0225] The data packets in the above-mentioned data packet group carry the identity tag information of the data packets in the data packet group, which may be the data packets in the data packet group carrying the end marker information of the data packet or other start, end or member and composition identity tag information, which is beneficial to the processing of the receiving end and thus improves the reliability of data transmission.

[0226] When the second RB completes transmitting a data packet group, resetting the transmission variable corresponding to the second RB may be resetting and clearing the transmission variable of layer 2 so that the second RB can quickly transmit other data content or be recovered, thereby improving the utilization rate of RB resources or saving RB overhead.

[0227] The queue identifier of the second queue carried by the data packet in the above second data content is used to indicate that the data packets in the second queue can be independently subjected to layer 2 related operations, such as independent sorting and security processing, so as to improve data processing efficiency.

[0228] The data packet in the second data content carries a complete count value (COUNT value), which makes it easier for the receiving end to perform independent sorting operations and security removal operations, etc., so as to improve data processing efficiency.

[0229] As an optional implementation manner, when the terminal is a transmitting end, the method further includes:

[0230] Before sending the second data content through the second queue or inserting the second data content in the data content set into the first queue for processing, the terminal buffers the PDCP SDU corresponding to the second data content.

[0231] The above-mentioned caching of the PDCP SDU corresponding to the second data content can be a case where the second data content is inserted, and the original PDCP SDU corresponding to the second data content is cached to facilitate the insertion and reordering of data packets / groups at any time, thereby avoiding the situation where the newly inserted data packet is assigned the earliest SN and other data have to be processed by PDCP&RLC again, so as to improve the data transmission processing efficiency.

[0232] As an optional implementation manner, when the terminal is a receiving end, the method further includes:

[0233] The terminal performs a receiving process, wherein the receiving process satisfies one of the following:

[0234] The first data content needs to be delivered to the upper layer in order;

[0235] In the case where the second data content includes discrete data content, the discrete data content does not need to be delivered to the higher layer in sequence;

[0236] In the case where the second data content includes data packet groups, data packets within the same data packet group need to be delivered to the upper layer in sequence, while data packet groups between different data packet groups do not need to be delivered to the upper layer in sequence;

[0237] In the case where the second data content includes a data packet group, the receiving variable is reset when one data packet group is received.

[0238] The above-mentioned need to deliver the first data content to the upper layer in sequence can be processed according to the sequence delivery high-level process defined by the protocol, such as receiving and sorting according to the different AM and UM configurations of the RLC entity and the PDCP entity, and delivering the high-level operation in sequence as needed.

[0239] The above discrete data content does not need to be delivered to the upper layer in sequence. The discrete data content does not need to be sorted. The sequential delivery and reordering functions can be turned off and the data will be delivered to the upper layer upon receipt to improve data processing efficiency.

[0240] The data packets within the same data packet group mentioned above need to be delivered to the upper layer in sequence, while different data packet groups do not need to be delivered to the upper layer in sequence. If it is data packet group processing, the data packets within a data packet group need to be continuous, reordered or delivered in sequence, while for data packet groups, sorting is not required to improve data processing efficiency.

[0241] The above-mentioned resetting of the receiving variable after receiving a data packet group can be a reordering or sequential delivery function according to the data packet group, or according to the configuration or negotiation between the sending and receiving ends, the receiving variable of the receiving end can also be cleared, reset or initialized after receiving a group of data packet groups, so as to start receiving the next data packet group from a brand new state to improve data processing efficiency.

[0242] As an optional implementation, the method further includes:

[0243] The terminal reports capability information of the terminal for the layer 2 operation.

[0244] The capability information may indicate whether the terminal supports the layer 2 operation in an explicit or implicit manner.

[0245] For example, the capability information includes at least one of the following:

[0246] Version information of the terminal;

[0247] Capability information of the layer 2 operation binding;

[0248] Indication information used to indicate whether the terminal supports the layer 2 operation;

[0249] The layer 2 operations supported by the terminal include at least one processing mode;

[0250] At least one parameter related to the layer 2 operation supported by the terminal.

[0251] The version information of the above-mentioned terminal can indicate whether the above-mentioned terminal supports the above-mentioned layer 2 operation. If the terminal is a 6G version, the above-mentioned layer 2 operation is supported by default.

[0252] The capability information bound to the above-mentioned layer 2 operation is used to indicate the capability bound to the layer 2 operation, such as the terminal's ability to support 6G enhanced L2 processing mode, which includes supporting the above-mentioned layer 2 operation.

[0253] The above indication information is used to explicitly indicate whether the terminal supports the above layer 2 operation, for example, 1 bit explicitly indicates support for the above layer 2 operation. If it is not carried, it means that the terminal does not support the above layer 2 operation.

[0254] At least one parameter involved in the layer 2 operation supported by the above-mentioned terminal may be specific capability information of the terminal supporting the above-mentioned layer 22 operation, for example: the terminal supports special priority processing for one or more data packets, or the terminal supports unified delay, scheduling and important packet processing for a data packet group, or the maximum number of sub-queues supported by the terminal, the maximum number of extended RBs supported by the terminal, etc.

[0255] In the above implementation, since the terminal's capability information for layer 2 operations is reported, the network side can perform corresponding transmission with the terminal based on the capability information reported by the terminal, or perform corresponding configuration for the terminal to improve the transmission performance between the terminal and the network side device.

[0256] In some implementations, the aforementioned Layer 2 operations may be indicated by separate terminal capabilities, such as one capability indication for each feature, one capability indication for a certain combination of features, or even one capability indication for all newly introduced special processes. The network configures the terminal with appropriate special Layer 2 operation configurations based on the capabilities reported by the terminal and the terminal's services; or the network explicitly or implicitly grants permission for the terminal to perform special Layer 2 operations. The terminal is only allowed to use special Layer 2 operations after obtaining network permission.

[0257] It should be noted that, in the embodiment of the present application, the data content can be either uplink data content or downlink data content.

[0258] In an embodiment of the present application, a terminal receives target information sent by a network side, and the target information includes at least one of the following: permission information for permitting layer 2 operations, and configuration information for layer 2 operations; wherein the layer 2 operations include: mapping the first data content in a data content set to a first RB, and mapping the second data content in the data content set to a second RB; or mapping the first data content in the data content set to a first queue of a third RB, mapping the second data content in the data content set to a second queue of the third RB, or inserting the second data content in the data content set into the first queue for processing. In this way, data content in the same data content set can be mapped to different RBs or queues, or the second data content in the data content set can be inserted into the first queue for processing, thereby improving the flexibility of data transmission processing.

[0259] Please refer to FIG8 , which is a flowchart of a capability information reporting method provided in an embodiment of the present application. As shown in FIG8 , the method includes the following steps:

[0264] The capability information may indicate whether the terminal supports the layer 2 operation in an explicit or implicit manner.

[0265] Since the terminal reports the capability information for the above-mentioned layer 2 operation, it is possible to map the data contents in the same data content set to different RBs or queues respectively, or insert the second data content in the data content set into the first queue for processing when the terminal supports the above-mentioned layer 2 operation, thereby improving the flexibility of data transmission processing.

[0273] The capability information bound to the above-mentioned layer 2 operation is used to indicate the capability bound to the layer 2 operation, such as the terminal's ability to support 6G enhanced L2 processing mode, which includes supporting the above-mentioned layer 2 operation.

[0274] The above indication information is used to explicitly indicate whether the terminal supports the above layer 2 operation, for example, 1 bit explicitly indicates support for the above layer 2 operation. If it is not carried, it means that the terminal does not support the above layer 2 operation.

[0275] At least one parameter involved in the layer 2 operation supported by the above-mentioned terminal may be specific capability information of the terminal supporting the above-mentioned layer 22 operation, for example: the terminal supports special priority processing for one or more data packets, or the terminal supports unified delay, scheduling and important packet processing for a data packet group, or the maximum number of sub-queues supported by the terminal, the maximum number of extended RBs supported by the terminal, etc.

[0276] In the above implementation, since the terminal's capability information for layer 2 operations is reported, the network side can perform corresponding transmission with the terminal based on the capability information reported by the terminal, or perform corresponding configuration for the terminal to improve the transmission performance between the terminal and the network side device.

[0277] In some implementations, the aforementioned Layer 2 operations may be indicated by separate terminal capabilities, such as one capability indication for each feature, one capability indication for a certain combination of features, or even one capability indication for all newly introduced special processes. The network configures the terminal with appropriate special Layer 2 operation configurations based on the capabilities reported by the terminal and the terminal's services; or the network explicitly or implicitly grants permission for the terminal to perform special Layer 2 operations. The terminal is only allowed to use special Layer 2 operations after obtaining network permission.

[0278] In an embodiment, since the terminal reports the capability information for the above-mentioned layer 2 operation, it is possible to map the data contents in the same data content set to different RBs or queues respectively, or insert the second data content in the data content set into the first queue for processing when the terminal supports the above-mentioned layer 2 operation, thereby improving the flexibility of data transmission processing.

Its specific implementation method can refer to the relevant description of the embodiment shown in Figure 5. In order to avoid repetition, this embodiment will not be repeated.

[0383] The following describes the method provided in the embodiments of the present application through multiple examples:

[0384] Example 1:

[0385] This embodiment mainly describes the network configuration and terminal capabilities. In this embodiment, it mainly includes the new configuration of the network for layer 2 (L2) special processing (ie, the above-mentioned layer 2 operation) and the reporting of terminal-related capabilities before the new configuration.

[0386] In some implementations, the introduction of new functions requires support from both terminal capabilities and network-side functions. In one case, if the function is a mandatory function for both the 6G terminal and the network, it can be assumed that both 6G terminals and 6G network nodes support the function, and whether the terminal and network node support the new function will be bound to version information or 6G capabilities. In another case, if the function is an optional function for both the 6G terminal and the network, the 6G terminal needs to carry the corresponding capability bit to report whether it supports the function, and the network node also needs to be configured or licensed to optionally support the function.

[0387] For a network node that supports new L2 operations (i.e., layer 2 operations in the above embodiment), it is necessary to first obtain the terminal's capabilities and confirm that the terminal supports the function before further configuring the function for the terminal. The terminal's capability information includes at least one of the following:

[0388] The terminal version information or capability information bound to the function, for example, if the terminal is a 6G version, it supports the new L2 operation function by default, or the terminal supports the 6G enhanced L2 processing capability, which includes support for the new L2 operation function;

[0389] Explicit capability indication information indicating whether the terminal supports the new L2 operation, for example, 1 bit explicitly indicating support for the function; if not carried, it means that the terminal does not support the function;

[0390] The terminal supports specific capability information for the new L2 operation, such as special priority processing for one or more data packets supported by the terminal, unified delay, scheduling, and important packet processing supported by the terminal for a group of data packets, the maximum number of subqueues supported by the terminal, the maximum number of extended RBs supported by the terminal, etc.

[0391] For the above-mentioned capability information, it can be packaged together with the capability information defined in the protocol and reported to the network side according to the traditional capability reporting process, or an independent capability acquisition process can be adopted, such as the terminal reporting when the network side indicates that it supports the function, or the network side explicitly queries the terminal for the capability information and then reports it, etc., to provide the network with corresponding capability information.

[0392] For a network-side entity that does not support the new L2 operation, even if it obtains the corresponding capabilities of the terminal, it may ignore it because it cannot identify the capability domain. Therefore, different support versions of the terminal and network entity can be well compatible and collaborative.

[0393] When a network entity supporting the new L2 operation obtains a report of terminal-related capabilities and decides to configure the new L2 operation for the terminal based on its own algorithm, service requirements, or terminal preferences, it may include at least one of the following:

[0394] Whether to enable the new L2 operation switch for all RBs that meet the configuration conditions of the terminal. The so-called RBs that meet the configuration conditions are determined by some default rules or network configuration rules. For example, the simplest rule is that SRBs cannot configure or enable new L2 operation functions, and only DRBs can configure or enable new L2 operation functions;

[0395] For terminals, based on RB granularity, you can configure whether to enable the new L2 operation switch.

[0396] Configure whether to enable the L2 new operation switch for the terminal's RB-based uplink, downlink, or uplink and downlink;

[0397] Some detailed parameters related to the new L2 operation function, such as additional bearer configuration (which is the primary bearer, the specific number and configuration of secondary bearers), the maximum number of subqueues, etc.

[0398] After the network is configured to enable new L2 processing, the terminal performs sending and receiving processing according to the new operation, otherwise it processes in the traditional way.

[0399] Network-side reconfiguration includes both reconfiguration within a cell and reconfiguration in handover scenarios. The handling methods include at least one of the following:

[0400] 1. When the original configuration does not enable new L2 operations and the target configuration enables new L2 operations,

[0401] The transmitting end operates the L2 entity according to the mechanism defined in the protocol, such as whether to perform PDCP re-establishment, RLC re-establishment, preservation of PDCP COUNT variables for AM entities, and initialization of PDCP COUNT variables for UM entities.

[0402] The sender starts sending data using the new L2 operation and its configuration from the first unsent packet (UM) or the first unacknowledged packet (AM). If a certain packet group is involved, the new L2 operation starts from the first packet in the packet group.

[0403] The receiving end is generally not affected much. The L2 entity operates according to the defined process of the protocol and performs necessary reordering of received data as needed.

[0404] 2. When the original configuration enables new L2 operations and the target configuration does not enable new L2 operations,

[0405] The sender operates the L2 entity according to the protocol-defined mechanism, starting with the first unsent packet (UM) or the first unacknowledged packet (AM) using traditional operations to send data.

[0406] The receiving end is generally not affected much. The L2 entity operates according to the defined process of the protocol and performs necessary reordering of received data as needed.

[0407] In some cases, the deletion of auxiliary RBs or subqueues may be involved. In this case, the auxiliary queues are processed as the sender and receiver of existing RB deletions. Subqueues are generally maintained only on the sender side. The subqueues are merged into the unified queue, and traditional operations are used for subsequent data processing.

[0408] 3. When the original configuration starts a new L2 operation and the target configuration also starts a new L2 operation,

[0409] The sender operates the L2 entity according to the protocol-defined mechanism and continues to send data using the new L2 operation and its configuration starting from the first unsent packet (UM) or the first unacknowledged packet (AM). If a certain packet group is involved, the new L2 operation is continued for that packet group.

[0410] The receiving end is generally not significantly affected. The L2 entity operates according to the protocol's defined process, and the received data is reordered as needed.

[0411] Example 2:

[0412] This embodiment mainly describes the L2 multi-RB mapping method.

[0413] In this embodiment, an operation method is introduced for mapping data packets and data packet groups with special requirements to L2 secondary RBs for special processing.

[0414] The specific schematic diagram is shown in Figure 6. It can be seen that the characteristic of this method is that data packets or data packet groups with special QoS requirements or transmission requirements (the above-mentioned second data content) can be mapped to an independent RB regardless of whether they belong to different QoS flows, thereby utilizing independent RBs for better transmission control.

[0415] First, this approach breaks the traditional QoS flow-to-RB mapping rule, so the configuration needs to be enhanced.

[0416] In the traditional QoS flow to RB mapping rules, for example, the same IP five-tuple data flow can be mapped to a QoS flow because it requires the same transmission attributes. Even another IP five-tuple data flow can be mapped to this QoS flow because it is the same or similar service. A typical scenario is such as opening two HTTP web pages. When the transmission characteristics of this QoS flow are sent to the base station, it will carry its QoS configuration (profile) and other parameters. Based on these parameters, the base station maps the QoS flow to a DRB and configures the DRB with relevant L2 transmission mode and priority, guaranteed bit rate and other parameters to ensure that data transmission meets QoS requirements.

[0417] However, in some scenarios (such as entering the 6G stage), service data is no longer a relatively single transmission attribute, or even for services that are the same or similar to 5G, it is necessary to distinguish some important data in it and treat them differently for transmission, so as to have better transmission efficiency and service experience. Therefore, the mapping between service data packets and QoS flows can be dynamic, and the mapping between QoS flows and RBs can also be dynamic. For example: for data flows of the same IP 5-tuple, important data or data packet groups with associated attributes can be distinguished and mapped to independent QoS flows (such as the example of method (2) in Figure 6), or even if they are mapped to the same QoS flow as ordinary data (such as the example of method (1) in Figure 6), the next step is to map these important data or data packet groups with associated attributes to independent RBs so that they can be treated differently.

[0418] The specific implementation is as follows:

[0419] The mapping of data packets to QoS flows falls within the domain of the core network, which dynamically manages the mapping, distinguishing different data packets or groups of data packets with different QoS flows, or explicitly marking special groups of data packets, such as PDU set markings, or having special processing parameters, and notifying the RAN side of this.

[0420] During the bearer establishment phase, the core network notifies the base station whether these data flows require special packet or special packet group processing (i.e., the second data content mentioned above), and what special operations these special packets / groups require, such as TCP ACK / feedback optimization processing, XR PDU Set packet group processing (carrying the transmission delay requirements of the entire set, whether there is a header packet, whether there is an associated deletion requirement, the maximum number of parallel packet groups), etc., and whether these special packets are distinguished by carrying information along the channel or using different QoS flows.

[0421] After receiving configuration information from the core network, the base station manages RB establishment and QoS flow-to-RB mapping based on it. Based on parameters such as the presence of normal data and the maximum number of supported concurrent data packets / groups, the base station configures the appropriate number of RBs and determines the primary and secondary RBs. For example, if normal data (data that requires no special treatment) is present, a primary RB is established to transmit data packets without special attributes, while the number of secondary RBs can be determined based on the maximum number of concurrent data packets / groups. Secondly, regarding the mapping of QoS flows to RBs, if data packets with special attributes and normal data share the same QoS flow, the QoS flow will be mapped to both the primary RB and N secondary RBs, where N is in the range [1 to the maximum number of secondary RBs]. Alternatively, if data packets with special attributes and normal data share different QoS flows, the QoS flow for normal data can be mapped to the primary RB. The mapping between the remaining QoS flows and secondary RBs can be fully dynamic, meaning each QoS flow can be mapped to any of the secondary RBs, or different QoS flows can be grouped to restrict the mapping of certain secondary RBs.

[0422] Since specially processed data packets / groups have a certain upper limit on the number or life cycle, for example, a TCP ACK / feedback packet may be one or several individual data packets, and an XR PDU set is the entire N data frames that make up an image. Therefore, after a specially processed data packet / group occupies a secondary RB to complete transmission, the secondary RB can carry other special data packets / groups, thus achieving dynamic mapping and dynamic management.

[0423] The second step is to complete the basic QoS parameter configuration, RB configuration and mapping configuration, followed by the data processing process at the sending end.

[0424] First, the data must be identified. If it carries a separate QoS flow ID or other independent packet-borne indicators or parameters, the L2 transmitter can distinguish special data packets / groups and map them to available secondary RBs, while mapping normal data to primary RBs. These indicators or parameters include, but are not limited to, explicit indications from TCP ACK / feedback packets or attributes read from specific fields in the TCP packet header, the PDU set ID of an XR PDU set packet, aggregate delay parameters, and characteristics of aggregate deletion packets.

[0425] In particular, although TCP ACK / feedback packets are important data, timely transmission to the other end will greatly promote the reverse data rate. However, since TCP ACK / feedback packets generally also carry data and sequence numbers in this direction, if only TCP ACK / feedback packets are prioritized, it will cause an SN gap or packet loss judgment in this direction, thereby causing adverse operations such as TCP slow start, and reducing the rate in this direction. Therefore, when prioritizing TCP ACK / feedback packets or inserting them into independent secondary RBs, it is possible to consider inserting data of the same IP 5-tuple or the same TCP flow that is currently in the queue but has not yet been transmitted or confirmed into independent secondary RBs for priority processing. Alternatively, the TCP ACK / feedback packets can be prioritized in independent RBs only after the data of the same IP 5-tuple or the same TCP flow that is currently in the queue but has not yet been transmitted or confirmed is successfully transmitted.

[0426] For PDU Set, data packets belonging to the same PDU set must be mapped to the same secondary RB, and one secondary RB can serve one PDU Set and then insert another new PDU set for further processing, which is equivalent to dynamic sequential use.

[0427] Secondly, for data packets inserted into independent RBs or secondary RBs, at least one of the following processing rules shall be applied during specific transmission:

[0428] First, the guaranteed bit rate is calculated for the associated RBs, including the secondary RB and the primary RB. That is, during LCP processing, the guaranteed bit rate and token bucket rules are summed for a group of associated RBs (including the primary RB and N secondary RBs).

[0429] Secondly, if it is an important data packet with additional latency requirements, it needs to be processed first. For example, TCP ACK / feedback packets, if there are no other earlier TCP packets in this direction, are mapped to a secondary RB. This secondary RB can have at least a higher priority than the primary RB. That is, the TCP ACK / feedback packet can be transmitted in advance in the queue of the primary RB, regardless of the first-come, first-out rule. This allows it to reach the other end as soon as possible, update the other end's acknowledgment and sending status, release and increase the sending window, and thus greatly improve the transmission rate in the reverse direction. The processing priority of TCP ACK / feedback packets and the priority of data in other secondary RBs can adopt a simple first-come, first-served principle, that is, equal priority. Alternatively, data that is about to expire can be given higher priority, and even priority can be configured or the terminal can implement its own priority to process them in order.

[0430] Alternatively, if a critical data packet requires higher reliability, the lower layers can be instructed to temporarily improve transmission reliability. For example, some transmission efficiency can be sacrificed in exchange for high reliability, with more reliable coding or transmission parameters, more HARQ retransmissions, and HARQ repetitions adopted to improve the reliability requirements of critical packets. This type of data, for example, includes special frames in XR data. These frames contain important header data for encoding and decoding. If lost or delayed, the entire data frame set will fail to be decoded and will be discarded.

[0431] Alternatively, if it is a data packet group, after inserting an independent RB, it will be treated uniformly. For example, the overall maximum discard delay of this data packet group will be calculated according to the time of the earliest inserted data packet. Once it times out, the entire data packet group will lose its function and can be deleted as a whole. The data that has been successfully transmitted will also waste resources. This data packet group can also adopt certain fairness principles with the data in the main RB. For example, it can be sorted by the arrival time of the first data packet in the data packet group. When it can be processed in order, the entire data packet group will be transmitted in sequence, and then other data will be transmitted. The transmission order between this data packet group and other data packet groups can also be based on the fairness principle. For example, it can be sorted by the arrival time of the first data packet in each data packet group. Each data packet group is transmitted in sequence. Once it is the turn of the data packet group, all the data of the entire data packet group will be transmitted together in sequence, and then the transmission of the next data packet group will begin. In addition, based on the above, the priority of the data packet group that is about to time out or the data packet group with less delay can be appropriately increased to facilitate that all data packets can be transmitted before timeout;

[0432] In particular, since the composition of a packet group may only be visible at the sending end, it is beneficial for the receiving end to process the packet if the outgoing air interface packet also carries certain indication information, such as end marker information or other start / end / member and composition information.

[0433] In particular, since there is not necessarily a correlation between one data packet group and the next data packet group, it is possible to consider resetting the L2 transmission variable to zero when the next data packet group occupies the auxiliary RB after the transmission of one data packet group is completed, for example, all sent or all confirmed by the other end.

[0434] For the receiving end, the receiving processing behavior includes at least one of the following:

[0435] First, the receiving end also needs to be configured accordingly, such as establishing primary and secondary RBs. Optionally, the mapping between QoS flows and RBs can also be configured. This step is similar to the configuration on the sending end. However, since the receiving end is primarily responsible for receiving processing, some overly detailed transmission parameters do not affect reception and do not need to be configured on the receiving end.

[0436] The second step is data reception and processing at the receiving end, which includes at least one of the following:

[0437] The receiving end can process the primary RB basically according to the existing process, such as receiving and sorting according to the different AM and UM configurations of the RLC entity and PDCP entity, and delivering them to higher-level operations in sequence as needed;

[0438] For secondary RB processing, if only discrete important data is processed, such as TCP ACK / feedback, sorting may not be necessary. In this case, the in-order delivery and reordering functions can be disabled, and the packets are delivered to higher layers upon receipt.

[0439] Alternatively, for the reception processing of the auxiliary RB, if it is the processing of a data packet group, the data packets within a data packet group need to be continuous / reordered / delivered in sequence and other functions, while for the data packet groups, sorting may not be required, so the reordering / delivery in sequence function is performed according to the data packet group, or according to the configuration or negotiation between the sending and receiving ends, after receiving a group of data packet groups, the receiving variables of the receiving end can also be cleared / reset / initialized, so that the next data packet group can be received from a brand new state.

[0440] Example 3:

[0441] This embodiment mainly describes the L2 sub-queue or queue management method.

[0442] In this embodiment, a new operation mode of L2 sub-queue or queue management (ie, the above-mentioned layer 2 operation) is introduced.

[0443] The specific diagram is shown in Figure 7. It can be seen that the characteristic of this method is that data packets or data packet groups with special QoS requirements or transmission requirements, regardless of whether they belong to different QoS flows, can be mapped to an independent sub-queue or inserted into the existing main queue according to priority or special processing requirements, thereby utilizing independent queues or queue management for better transmission control.

[0444] The following describes in detail how to configure and perform data operations:

[0445] First of all, this method can basically follow the traditional QoS flow to RB mapping rules. However, unlike the traditional first-come-first-out single simple queue, it requires more complex and intelligent sub-queue processing. Therefore, the configuration needs to be enhanced. If the configuration is not enhanced, everything can be left to the implementation.

[0446] In some scenarios (such as entering the 6G stage), service data is no longer a relatively single transmission attribute, or even for services that are the same or similar to 5G, it is necessary to distinguish some important data in it and treat them differently for transmission, so as to have better transmission efficiency and service experience. Therefore, the mapping between service data packets and QoS flows can be dynamic, and the mapping between QoS flows and RBs can also be dynamic. For example, for data flows with the same IP 5-tuple, important data or data packet groups with associated attributes can be distinguished and mapped to independent QoS flows (such as the example of method (2) in Figure 7), or even if they are mapped to the same QoS flow as ordinary data (such as the example of method (1) in Figure 7), the next step is to map these important data or data packet groups with associated attributes to independent sub-queues or process them separately in the main queue so that they can be treated differently.

[0447] The specific implementation is as follows:

[0448] The mapping of data packets to QoS flows falls within the domain of the core network, which dynamically manages the mapping, distinguishing different data packets or groups of data packets with different QoS flows, or explicitly marking special groups of data packets, such as PDU set markings, or having special processing parameters, and notifying the RAN side of this.

[0449] During the bearer establishment phase, the core network notifies the base station whether these data flows require special packet or special packet group processing (i.e., the second data content mentioned above), and what special operations these special packets / groups require, such as TCP ACK / feedback optimization processing, XR PDU Set packet group processing (carrying the transmission delay requirements of the entire set, whether there is a header packet, whether there is an associated deletion requirement, the maximum number of parallel packet groups), etc., and whether these special packets are distinguished by carrying information along the channel or using different QoS flows.

[0450] The base station receives configuration information from the core network and completes RB establishment and QoS flow-to-RB mapping in a traditional manner. Based on this information, it manages the mapping of QoS flows or special data packets / groups to subqueues. The base station configures the appropriate number of subqueues based on parameters such as the presence of normal data and the maximum number of concurrent data packets / groups supported. For example, if normal data (that is, data that does not require special treatment) is present, a main queue is established to transmit data packets without any special attributes, and the number of subqueues can be determined based on the maximum number of concurrent data packets / groups. Secondly, regarding the mapping of QoS flows to subqueues, if special data packets and normal data use the same QoS flow, the QoS flow will be mapped to both the main queue and N subqueues, where N is in the range [1 to the maximum number of subqueues]. Alternatively, if special data packets and normal data packets use different QoS flows, the QoS flow for normal data can be mapped to the main queue. The mapping between other QoS flows and subqueues can be fully dynamic, meaning that each QoS flow can be mapped to any subqueue, or different QoS flows can be grouped and limited to specific subqueues.

[0451] Since specially processed data packets / groups have a certain upper limit on the number or lifecycle, for example, a TCP ACK / feedback packet may be one or several individual data packets, while an XR PDU set is the entire N data frames that make up an image. Therefore, after a specially processed data packet / group occupies a subqueue and completes transmission, the subqueue can carry other special data packets / groups, thus achieving dynamic mapping and dynamic management.

[0452] The second step is to complete the basic QoS parameter configuration, RB configuration and mapping configuration, followed by the data processing process at the sending end.

[0453] First, the data needs to be identified. If it carries a unique QoS flow ID or other independent packet-specific indicators or parameters, the L2 transmitter can distinguish special data packets / groups and map them to available subqueues, while mapping normal data to the main queue. These indicators or parameters include, but are not limited to, explicit indications from TCP ACK / feedback packets or attributes read from specific fields in the TCP packet header, the PDU set ID and / or aggregate delay parameters of XR PDU set packets, and characteristics of aggregate drop packets.

[0454] In particular, although TCP ACK / feedback packets are important data, timely transmission to the other end will greatly promote the reverse data rate. However, since TCP ACK / feedback packets generally also carry data and sequence numbers in this direction, if only TCP ACK / feedback packets are prioritized, it will cause an SN gap or packet loss judgment in this direction, thereby causing adverse operations such as TCP slow start, and reducing the rate in this direction. Therefore, when prioritizing or inserting TCP ACK / feedback packets into independent subqueues, it is possible to consider simultaneously inserting data of the same IP 5-tuple or the same TCP flow that is currently in the queue but has not yet been transmitted or confirmed into the independent subqueue for priority processing. Alternatively, the TCP ACK / feedback packets can be prioritized in the independent subqueue only after the data of the same IP 5-tuple or the same TCP flow that is currently in the queue but has not yet been transmitted or confirmed is successfully transmitted.

[0455] For PDU Set, data packets belonging to the same PDU set must be mapped to the same sub-queue, and one sub-queue can serve one PDU Set and then insert another new PDU set for further processing, which is equivalent to dynamic sequential use.

[0456] Secondly, for packets inserted into independent subqueues, at least one of the following processing rules must be followed during transmission:

[0457] First, the subqueues and the main queue belong to the same RB, so the guaranteed bit rate is calculated together. That is, during LCP processing, the guaranteed bit rate and token bucket rules can be summed for the same RB (including the main queue and N subqueues).

[0458] Secondly, if a critical data packet has additional latency requirements and requires priority processing, such as a TCP ACK / feedback packet, and there are no earlier TCP packets in this direction, this critical data packet is mapped to a subqueue with a priority at least higher than that of the main queue. This means that the TCP ACK / feedback packet can be transmitted in advance, rather than following the first-in-first-out rule of traditional queues, so that it can reach the other end as soon as possible, update the other end's acknowledgment and send status, and free up and increase the send window, thereby significantly improving the transmission rate in the reverse direction. The processing priority of TCP ACK / feedback packets and the priority of data in other subqueues can be handled on a simple first-come, first-served basis, that is, equal priority. Alternatively, data that is about to expire can be given higher priority, and even priority can be configured or implemented by the terminal itself, so that they can be processed in order.

[0459] If a queue is managed in a manner such as that shown in (2) of FIG7 , then the important data packet will be inserted into the earliest possible position, i.e., the earliest position that does not affect the order of the TCP flow in this direction, thereby enjoying priority processing of the feedback of this TCP flow in a queue;

[0460] Alternatively, if a critical data packet requires higher reliability, the lower layers can be instructed to temporarily improve transmission reliability. For example, some transmission efficiency can be sacrificed in exchange for high reliability, with more reliable coding or transmission parameters, more HARQ retransmissions, and HARQ repetitions adopted to improve the reliability requirements of critical packets. This type of data, for example, includes special frames in XR data. These frames contain important header data for encoding and decoding. If lost or delayed, the entire data frame set will fail to be decoded and will be discarded.

[0461] Alternatively, if it is a data packet group, after being inserted into an independent sub-queue, it will be treated uniformly. For example, the overall maximum discard delay of this data packet group will be calculated according to the time of the earliest inserted data packet. Once it times out, the entire data packet group will become useless and can be deleted as a whole. The data packet that has been successfully transmitted will also waste resources. This data packet group can also adopt certain fairness principles with the data in the main queue. For example, it can be sorted by the arrival time of the first data packet in the data packet group. When it can be processed in order, the entire data packet group will be transmitted in sequence, and then other data will be transmitted. The transmission order between this data packet group and other data packet groups can also be based on the fairness principle. For example, it can be sorted by the arrival time of the first data packet in each data packet group. Each data packet group is transmitted in sequence. Once it is the turn of the data packet group, all the data of the entire data packet group will be transmitted together in sequence, and then the transmission of the next data packet group will begin. In addition, based on the above, the priority of the data packet group that is about to time out or the data packet group with less delay can be appropriately increased to facilitate that all data packets can be transmitted before the timeout.

[0462] As described above, if a data packet group is inserted into a main queue (such as the second method in Figure 7), the position of the data packet group in the main queue can be determined according to the arrival order of the first data packet of the data packet group. For example, the first data packet and other ordinary packets adopt the first-come-first-out principle, and the data of other data packet groups also adopt the first-come-first-out principle or the configured priority principle or the principle of raising the priority based on the expiration of the data packet group. However, the data belonging to the same data packet group need to be arranged continuously. When the order of a data packet group needs to be raised or lowered due to priority or timeout, the entire data packet group is moved forward or backward as a whole;

[0463] In particular, since the composition of a packet group may only be visible at the sending end, it is beneficial for the receiving end to process the packet if the outgoing air interface packet also carries certain indication information, such as end marker information or other start / end / member and composition information.

[0464] In particular, whether processing data packets / groups in sub-queues or inserting them into the main queue, in principle, the first-in-first-out principle is actually violated. L2 processing, such as PDCP and RLC, has certain pre-processing requirements in order to meet the needs of high-speed transmission. That is, the data cached in the queue may have executed PDCP SN allocation, security operations, PDCP PDU generation, RLC SN allocation, RLC PDU generation and other operations as soon as possible after reaching L2. If an operation that disrupts the processing order is inserted after a series of operations, it is generally impossible to perform, or the cost is relatively high. It is equivalent to all the allocated SNs having to be removed and started over, and the newly inserted data packets having to be assigned the earliest SN, and the other data have to be processed by PDCP & RLC again, and the processing efficiency is very low. Therefore, there are two possible solutions. One is to cache the original PDCP SDU in case of possible insertion to facilitate the insertion and reordering of data packets / groups at any time. The other is to introduce a subqueue identifier in the L2 operation and carry it in the data packet. The subqueue identifier can be used for separate sorting and security processing of the subqueue, or the subqueue data carries a complete COUNT value to facilitate independent sorting and security operations at the receiving end.

[0465] For the receiving end, the receiving processing behavior includes at least one of the following:

[0466] First, the configuration of the receiving end is relatively simple. It only requires establishing RBs and configuring the most basic QoS flow-to-RB mapping. This step is basically the same as the configuration of the sending end. However, since the receiving end is mainly responsible for receiving processing, some overly detailed sending configurations do not affect reception and do not need to be configured for the receiving end. For example, there is no need to configure and distinguish between the main queue and subqueues, because this is the operation of the sending end.

[0467] The second step is data reception and processing at the receiving end, which includes at least one of the following:

[0468] The receiving end can process an entire RB basically according to the existing process, such as receiving and sorting according to the different AM and UM configurations of the RLC entity and PDCP entity, and submitting them to higher-level operations in order as needed;

[0469] For special data processing, if only discrete important data is processed, such as TCP ACK / feedback, sorting may not be required and it can be delivered to the upper layer immediately after receipt.

[0470] Alternatively, for the processing of data packet groups, functions such as continuity / reordering / sequential delivery are required between data packets within a data packet group, while sorting is not required between data packet groups, so reordering / sequential delivery functions are performed according to the data packet groups.

[0471] It should be noted that the embodiments of the present application can be applied to 5G or 6G, etc., and are not limited to Uu. They can be extended to other different versions without specific limitation.
