Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a communication method, device, terminal, and storage medium. Background Technology

[0002] The 3rd Generation Partnership Project (3GPP) Release 19 (R19) agrees to support configuring multiple remaining delay budget reporting thresholds for a Logical Channel Group (LCG). Each remaining delay budget reporting threshold corresponds to a remaining delay budget range, used to configure the terminal to generate multiple pairs of delay status information for that LCG to generate a Delay Status Report (DSR). Each delay status information pair corresponds to: the sum of the data size of data packet A, and the remaining delay budget of the data packet with the smallest remaining delay budget in data packet A. Data packet A is the data packet to be transmitted in the LCG whose remaining delay budget falls within the remaining delay budget range of any given delay status information pair.

[0003] In related technologies, when generating DSR for an LCG, since one or more data packets to be transmitted included in the LCG may have been delivered to the Radio Link Control (RLC) layer by the terminal's Packet Data Convergence Protocol (PDCP) layer, both the PDCP layer and the RLC layer need to separately count the amount of data corresponding to each delay state information pair when generating the amount of data corresponding to each delay state information pair for an LCG. For example, taking 10 data packets to be transmitted in the LCG, namely data packets 1 to 10, assuming that the remaining delay budget of data packets 1 to 4 is within the remaining delay budget of delay status information pair 1, and data packets 1 and 2 are submitted to the RLC layer by the PDCP layer, then when the terminal's PDCP layer calculates the amount of data corresponding to delay status information pair 1, it needs to calculate the sum of the amounts of data packets 3 and 4. When the terminal's RLC layer calculates the amount of data corresponding to delay status information pair 1, it needs to calculate the sum of the amounts of data packets 1 and 2. Then, the sum of the amounts of data calculated by the PDCP layer and the RLC layer is determined as the amount of data corresponding to delay status information pair 1, thereby generating delay status information.

[0004] However, for data packets already submitted to the RLC layer, since the RLC layer lacks the remaining delay budget for the data packets, it cannot determine the range of the remaining delay budget corresponding to the data packets. Therefore, when calculating the data volume corresponding to a delay status information pair, the RLC layer cannot determine which data packets to be transmitted should be included in the data volume corresponding to that delay status information pair. Therefore, how the terminal generates the delay status information for the LCG when data from the LCG is submitted to the RLC layer by the PDCP layer is a problem that urgently needs to be solved.

[0035] To facilitate understanding of the solution in this application, the relevant technologies involved in this application will be explained below.

[0036] 1. XR services

[0037] Extended Reality (XR) services include AR (Augmented Reality) services, VR (Virtual Reality) services, and Mixed Reality (MR) services. Currently, popular XR services use H.264 encoding technology to compress image data, achieving the goals of saving bandwidth and ensuring image quality. Existing H.264 technology encodes image data into three types of image frames:

[0038] (1) An I-frame (Intra-coded picture) is a complete image frame that can generate and render images without relying on other frames;

[0039] (2) P-frame (Predicted picture) only contains image change information relative to the previous frame. The receiver needs to combine the previous frames to generate the current frame and complete the display on the receiving terminal.

[0040] (3) B-frame (Bidirectional predicted picture), used to indicate the changes in the current frame relative to the preceding and following frames. The receiver needs to combine the preceding and following frames to generate the current frame.

[0041] The preceding and following frames refer to the order based on the frame presentation time or the image acquisition time at the source. The actual sending and receiving times may be adjusted according to the image decoding time of the receiver. For example, the sender can send frames in the order of the receiver's image frame decoding time.

[0042] Different frame types correspond to different frame encoding methods, resulting in varying degrees of image compression. I-frames have the lowest compression level (i.e., the largest frame data size), P-frames have the moderate compression level (i.e., the moderate frame data size), and B-frames have the highest compression level (i.e., the smallest frame data size).

[0043] There are two transmission methods for XR images: transmission based on frame slice combination and transmission based on group of pitctures (GoP).

[0044] (1) Transmission method based on frame slice combination: a data frame is cut into multiple data blocks, and then the slices of multiple image frames are distributed and combined into multiple data blocks for transmission, so as to achieve the purpose of smoothing the traffic of an XR service data stream. This method greatly reduces the traffic fluctuation caused by the difference in I / P / B frame data volume, but the cross transmission between image frames significantly increases the transmission delay of image frames.

[0045] (2) Frame Set-Based Transmission: Based on the periodicity of the video stream, video frames are divided into video frame sets according to the period of the I-frame. An I-frame and all P-frames and B-frames preceding the next I-frame constitute a frame set. Image frames are transmitted and played at the receiver according to the frame period, and the time interval between the arrival times of adjacent image frames is one frame period. The frame set-based transmission method avoids the mixed transmission of image frames, ensuring timely transmission of generated image frames. Due to the different compression levels among I, P, and B frames, the frame data rate fluctuates.

[0046] 2. Protocol Data Unit (PDU) group for XR services

[0047] Currently, in 3GPP discussions, XR service data is modeled as a PDU set. A PDU set includes a group of PDUs, allowing for Quality of Service (QoS) management based on PDU sets during data transmission in the wireless network. Depending on the different video data transmission methods described above, one PDU set can correspond to one image frame, such as a complete P-frame or B-frame, or an XR service data slice. Another image frame can contain several PDU sets. For example, when image frames are transmitted according to the left and right eye lines of sight, the left-eye image data of one image frame corresponds to one PDU set, and the right-eye image data corresponds to another PDU set. Furthermore, when images are transmitted along the visual axis and non-visual axis directions, the visual axis image data corresponds to one PDU set, and the non-visual axis image data corresponds to another PDU set. The above are merely illustrative examples of PDU set modeling; other forms of PDU set modeling may exist and do not constitute a limitation on the implementation of this patent.

[0048] 3. Transmission of XR services in NR networks

[0049] According to the current 3GPP protocol, when an uplink XR data packet from a UE arrives in the PDCP layer buffer from the application layer, a PDCP discard timer is started with the initial value pre-configured by the base station. During the operation of the PDCP discard timer, the base station can schedule the UE to transmit the data packet to the base station. If the corresponding PDCP discard timer expires and the data is still not successfully transmitted, the data packet is discarded.

[0050] 4. Packet Delay Budget (PDB)

[0051] Different services have different QoS management requirements. In 3GPP networks, QoS parameters include service data rate requirements, service data transmission latency requirements, and service data transmission reliability requirements (e.g., packet loss rate). The network can set different QoS parameters based on the user experience goals of different services.

[0052] For latency-sensitive services, end-to-end latency requirements are generally quite stringent. Based on these end-to-end latency requirements, the latency budget for each segment of the data transmission path is determined. When latency-sensitive service data is transmitted over the 3GPP air interface, the network determines the corresponding air interface latency budget and schedules resources to ensure that data transmission is completed within the given latency budget.

[0053] According to the current protocol, the PDB window of a data packet or the delay budget (PSDB) window of a data packet set can be understood as the runtime window of the corresponding PDCP discardTimer, that is, the time window between the start of the PDCP discardTimer and the timeout of the PDCP discardTimer. If the PDCP discardTimer times out and the corresponding data packet has not been successfully transmitted, the PDCP entity will discard the PDCP PDU or the corresponding RLCPDU that has not been successfully transmitted.

[0054] When transmitting XR image data, the network can be configured to transmit data based on PDU sets. In this case, the network can configure the air interface transmission delay budget for each PDU set. The data packets contained in a PDU set correspond to a transmission window determined according to the PSDB. Based on the current conclusions, the network can configure the UE's corresponding PDCP discardTimer according to the PSDB to determine the transmission window of the PDU set or the data packets belonging to the PDU set.

[0055] 5. Latency status reporting and emergency uplink latency data

[0056] In Release 18 (3GPP TS 38.321v18.0, 3GPP TS 38.331v18.0), the protocol supports reporting latency status by LCG. When the remaining latency budget of the data with the smallest remaining latency budget in an LCG falls below a pre-configured threshold (remainingTimeThreshold), a latency status report for that LCG can be triggered. Data in an LCG with a remaining latency budget below this threshold is called latency-critical data. In an LCG's latency status report, the UE indicates the remaining latency budget of the data with the smallest remaining latency budget in an LCG and the amount of buffered data whose remaining latency budget is below the preset threshold. In the Release 18 standard, when an LCG triggers latency status information reporting, it only reports a pair of remaining latency budget values ​​and the corresponding amount of latency-critical data.

[0057] In the PDCP protocol, the PDCP entity corresponding to a Logical Channel (LCH) determines the remaining delay budget of a data packet based on the residual time of the packet's discardTimer.

[0058] Figure 2The DSR format defined for R18 can be found in protocol 38.321v18.1.0. LCGi indicates whether the delay state information of LCG i is included in the DSR, where i∈[0,7]. The delay state information of an LCG includes:

[0059] (1)BT indicates whether the Buffer Status Report (BSR) table uses the table defined in the protocol prior to R18 or the new BSR table defined in R18;

[0060] (2) Remaining Time Budget;

[0061] (3) The amount of data corresponding to the time-delay emergency data.

[0062] Furthermore, according to the existing PDCP protocol, when the discardTimer residual value of a PDCP Service Data Unit (SDU) is lower than the remainingTimeThreshold, and the corresponding RLC PDU has not been submitted to the Medium Access Control (MAC) layer's MAC PDU for transmission, the PDCP SDU can be identified as urgent delay data. If the PDCP SDU has already been submitted to the RLC layer, the PDCP layer sends a delay urgency indication to the RLC layer. The RLC layer will include data packets with corresponding delay urgency indications that have not been submitted to the MAC PDU for transmission in the amount of urgent delay data. In addition, for PDCP status PDUs, RLC status PDUs, and RLC PDUs waiting for retransmission in RLC Acknowledged Mode (AM), as well as RLC PDUs whose discardTimer has expired but which the UE has not discarded to maintain the continuity of the RLC PDU sequence number, these will also be included in the amount of urgent delay data by the RLC layer. For an LCG, the sum of the latency urgent data calculated by the corresponding PDCP layer and the latency urgent data calculated by the corresponding RLC layer is the latency urgent data amount of that LCG.

[0063] In the discussions of R19, it has been agreed to support configuring multiple remaining latency budget reporting thresholds for an LCG, corresponding to multiple remaining latency budget ranges. This is used to configure the UE to generate multiple pairs of latency status information reports for that LCG, containing "remaining latency budget and corresponding data volume". As an example, when the base station configures N remaining latency budget reporting thresholds (RRTT) for the UE's LCG 1, in ascending order: RRTT1, RRTT2, ..., RRTTN, it can report a maximum of N pairs of latency status information for LCG1, containing "remaining latency budget and corresponding data volume". The first latency status information corresponds to the remaining latency budget and the data volume of the data packet with the smallest remaining latency budget among the data whose remaining latency budget is less than RRTT1; the nth (n>1) latency status information corresponds to the remaining latency budget and the data volume of the data packet with the smallest remaining latency budget among the data packets whose remaining latency budget is in the range [RRTTn-1, RRTTn). The protocol can also stipulate that when the base station configures N RRTTs for the UE's LCG 1, in ascending order: RRTT1, RRTT2, ..., RRTTN, the UE can generate a delay status report for the UE including up to N+1 delay status information pairs. The remaining delay budget range corresponding to the first delay status information pair is the same as the remaining delay budget range corresponding to the nth (n<=N) delay status information pair. The remaining delay budget range of the N+1th delay status information pair is [RRTTN, +∞).

[0064] The communication method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0065] In this embodiment, since the RLC layer of the terminal can receive the data packet of the first LCG transmitted by the PDCP layer of the terminal, and receive at least one of the following: the remaining delay budget range corresponding to the data packet, the sequence number of the remaining delay budget range corresponding to the data packet, and the sequence number of the delay status information pair corresponding to the data packet, i.e. the aforementioned delay-related information, when the RLC layer of the terminal calculates the first data volume corresponding to the remaining delay budget range, it can determine whether the data volume of the received data packet should be included in the first data volume based on the aforementioned delay-related information. This allows the terminal to generate the delay status information corresponding to the remaining delay budget range, i.e., the delay status information of the first LCG, based on the first data volume calculated by the RLC layer and the data volume corresponding to the remaining delay budget range calculated by the PDCP layer.

[0066] Figure 3 A flowchart illustrating the communication method provided in the embodiments of this application is shown below. Figure 3As shown, the communication method may include the following steps 201 and 202.

[0067] Step 201: The RLC layer of the terminal receives data packets and latency-related information from the PDCP layer of the first LCG.

[0068] In some embodiments of this application, the above-mentioned data packet can be understood as: the data packet of the first LCG being passed from the PDCP layer to the RLC layer.

[0069] In some embodiments of this application, the aforementioned latency-related information refers to latency-related information corresponding to data packets.

[0070] It is understandable that when the data packet of the first LCG is passed from the PDCP layer to the RLC layer, the terminal's PDCP layer can also send the latency-related information corresponding to the data packet to the terminal's RLC layer.

[0071] In the embodiments of this application, the aforementioned latency-related information includes at least one of the following:

[0072] The remaining latency budget range corresponding to the data packet;

[0073] The sequence number of the remaining delay budget range corresponding to the data packet;

[0074] The sequence number of the delay status information pair corresponding to the data packet.

[0075] Step 202: The terminal's RLC layer calculates the first data volume corresponding to the remaining latency budget range based on latency-related information and data packets.

[0076] In some embodiments of this application, the first data volume corresponding to the remaining latency budget range of the terminal statistics can be understood as: the data volume of all data packets whose remaining latency budget of the first LCG is within the aforementioned remaining latency budget range.

[0077] In some embodiments of this application, the first data volume corresponding to the remaining latency budget range of the terminal statistics can be understood as: the first data volume corresponding to the latency status information pair corresponding to the remaining latency budget range of the terminal statistics.

[0078] In some embodiments of this application, the remaining latency budget range corresponding to the data packet can be understood as: the remaining latency budget range in which the remaining latency budget of the data packet is located.

[0079] In some embodiments of this application, when a data packet is passed from the PDCP layer to the RLC layer, the PDCP layer of the terminal can determine the remaining delay budget range corresponding to the data packet based on the remaining delay budget of the data packet, and then send the remaining delay budget range corresponding to the data packet to the RLC layer.

[0080] In some embodiments of this application, when the aforementioned latency-related information includes the latency budget range corresponding to the data packet, after the terminal's RLC layer receives the latency-related information, when calculating the first data volume corresponding to the aforementioned latency budget range, it can determine whether the data volume of the data packet should be included in the first data volume based on the latency-related information.

[0081] In some examples, when calculating the first data volume corresponding to the aforementioned latency budget range, if the latency budget range is the same as the remaining latency budget range corresponding to the data packet, the terminal's RLC layer can include the data volume of the data packet in the first data volume.

[0082] It is understandable that when the terminal's RLC layer is calculating the amount of data corresponding to any latency budget range, it can include the amount of data of all data packets of the first LCG cached in the RLC layer corresponding to any latency budget range in the amount of data corresponding to any latency budget range.

[0083] In some embodiments of this application, the sequence number of the remaining delay budget range corresponding to the data packet can be understood as: the sequence number of the remaining delay budget range in which the remaining delay budget of the data packet is located.

[0084] In some embodiments of this application, when a data packet is passed from the PDCP layer to the RLC layer, the PDCP layer of the terminal can determine the remaining delay budget range corresponding to the data packet based on the remaining delay budget of the data packet, and then send the sequence number of the remaining delay budget range corresponding to the data packet to the RLC layer.

[0085] In some embodiments of this application, when the aforementioned latency-related information includes the sequence number of the latency budget range corresponding to the data packet, after the terminal's RLC layer receives the latency-related information, when calculating the first data volume corresponding to the aforementioned latency budget range, it can determine whether the data volume of the data packet should be included in the first data volume based on the sequence number of the latency budget range corresponding to the data packet.

[0086] In some examples, when calculating the first data volume corresponding to the aforementioned latency budget range, if the sequence number of the latency budget range is the same as the sequence number of the latency budget range corresponding to the data packet, the terminal's RLC layer can include the data volume of the data packet in the first data volume.

[0087] It is understandable that when the terminal's RLC layer is calculating the amount of data corresponding to any latency budget range, it can include the amount of data of at least one data packet A of the first LCG cached in the RLC layer into the amount of data corresponding to any latency budget range, and the sequence number of the remaining latency budget range corresponding to at least one data packet A is the same as the sequence number of any latency budget range.

[0088] In some embodiments of this application, the sequence number of the remaining delay budget range corresponding to the data packet may include any of the following:

[0089] The sequence number of the delay status information pair corresponding to the remaining delay budget range of the data packet;

[0090] The sequence number of the delay status information pair corresponding to the data packet.

[0091] In some embodiments of this application, the sequence number of the delay status information pair corresponding to the above data packet can be understood as: the sequence number of the delay status information pair corresponding to the remaining delay budget range in which the remaining delay budget of the data packet is located.

[0092] In some embodiments of this application, the remaining delay budget range corresponds one-to-one with the delay status information.

[0093] In some embodiments of this application, the correspondence between the remaining delay budget range and the delay state information pairs can be found in the following description:

[0094] When the first LCG is configured with N remaining latency budget reporting thresholds, the N remaining latency budget reporting thresholds can correspond to N remaining latency budget ranges or N+1 remaining latency budget ranges. For each remaining latency budget range, the terminal can report a pair of latency status information, where N is a positive integer.

[0095] Among them, any delay status information pair may include: the data volume of all data packets corresponding to the remaining delay budget range of the first LCG corresponding to any delay status information pair, and the remaining delay budget value of the data packet with the smallest remaining delay budget among all data packets;

[0096] For example: when two remaining latency budget reporting thresholds are configured in the first LCG, and the two remaining latency budget reporting thresholds are 5 and 8 respectively, the two remaining latency budget reporting thresholds can correspond to two remaining latency budget ranges, and the two remaining latency budget ranges are (0, 5) and [5, 8) respectively, then the terminal can report two pairs of latency status information; or, the two remaining latency budget reporting thresholds can correspond to three remaining latency budget ranges, and the three remaining latency budget ranges are (0, 5), [5, 8), and [8, ∞) respectively, then the terminal can report three pairs of latency status information. Taking the first LCG as an example, which is configured with two remaining latency budget reporting thresholds: 5 and 8, and the two remaining latency budget reporting thresholds correspond to three remaining latency budget ranges, the terminal needs to report three pairs of latency status information. The three pairs of latency status information are: latency status information pair 1, latency status information pair 2, and latency status information pair 3. Latency status information pair 1 corresponds to the remaining latency budget range (0, 5), latency status information pair 2 corresponds to the remaining latency budget range [5, 8), and latency status information pair 3 corresponds to the remaining latency budget range [8, ∞). Taking latency status information pair 1 as an example, latency status information pair 1 can include: the data volume of all data packets of the first LCG corresponding to the remaining latency budget range (0, 5) of latency status information pair 1, and the remaining latency budget value of the data packet with the smallest remaining latency budget among all data packets.

[0097] In some embodiments of this application, when a data packet is transmitted from the PDCP layer to the RLC layer, the PDCP layer of the terminal can obtain the latency status information pair corresponding to the remaining latency budget range of the data packet, and then send the sequence number of the latency status information pair to the RLC layer.

[0098] In some embodiments of this application, the first data volume corresponding to the remaining latency budget range mentioned above can also be understood as: the first data volume corresponding to the latency status information pair corresponding to the remaining latency budget range, that is, the terminal directly counts the corresponding data volume according to the sequence number of the latency status information pair.

[0099] In some embodiments of this application, when the aforementioned latency-related information includes the sequence number of a latency status information pair, after the terminal's RLC layer receives the latency-related information, when calculating the first data volume corresponding to the aforementioned latency budget range, it can determine whether the data volume of the data packet should be included in the first data volume based on the sequence number of the latency status information pair corresponding to the latency budget range and the sequence number of the latency status information pair included in the latency-related information.

[0100] In some examples, when the sequence number of the delay state information pair included in the delay-related information is the same as the sequence number of the delay state information pair corresponding to the delay budget range, the terminal's RLC layer can include the data volume of the data packet in the first data volume.

[0101] It can be understood that when the terminal's RLC layer counts the amount of data corresponding to any latency budget range, it counts the corresponding amount of data according to the sequence number of the latency state information pair corresponding to any latency budget range. That is, the amount of data of at least one data packet B of the first LCG cached in the RLC layer is included in the amount of data corresponding to any latency budget range. The sequence number of the latency state information pair corresponding to at least one data packet B is the same as the sequence number of the latency state information pair corresponding to any latency budget range, or the sequence number of the latency state information pair corresponding to the remaining latency budget range of at least one data packet B is the same as the sequence number of the latency state information pair corresponding to any latency budget range.

[0102] This application provides a communication method. Since the RLC layer of the terminal can receive the data packet of the first LCG transmitted by the PDCP layer of the terminal, and at least one of the following: the remaining delay budget range corresponding to the received data packet, the sequence number of the remaining delay budget range corresponding to the data packet, and the sequence number of the delay status information pair corresponding to the data packet, i.e., the aforementioned delay-related information, when the RLC layer of the terminal calculates the first data volume corresponding to the remaining delay budget range, it can determine whether the data volume of the received data packet should be included in the first data volume based on the aforementioned delay-related information. This allows the terminal to generate the delay status information corresponding to the remaining delay budget range, i.e., the delay status information of the first LCG, based on the first data volume calculated by the RLC layer and the data volume corresponding to the remaining delay budget range calculated by the PDCP layer.

[0103] In some embodiments of this application, the communication method provided in the embodiments of this application may further include the following step 301.

[0104] It should be noted that the terminal may execute step 301 before executing step 201.

[0105] Step 301: The PDCP layer of the terminal sends latency-related information to the RLC layer of the terminal.

[0106] In some embodiments of this application, the terminal's PDCP layer can simultaneously send data packets and latency-related information to the terminal's RLC layer; or, after sending data packets to the terminal's RLC layer, it can then send latency-related information to the terminal's RLC layer. The specific method can be determined based on actual usage requirements, and this application does not limit this.

[0107] In some embodiments of this application, step 301 described above can be implemented by step 301a as follows.

[0108] Step 301a: If the remaining delay budget of the data packet is within the remaining delay budget range, the PDCP layer of the terminal sends delay-related information to the RLC layer of the terminal.

[0109] Example 1: Suppose the network-side device configures two remaining latency budget reporting thresholds for the first LCG. If the two remaining latency budget reporting thresholds are 5 and 8 respectively from low to high, then the terminal can report three pairs of latency status information for the first LCG. The first latency status information pair 1 corresponds to the remaining latency budget range (0, 5), the second latency status information pair 2 corresponds to the remaining latency budget range [5, 8), and the third latency status information pair 3 corresponds to the remaining latency budget range [8, ∞).

[0110] If the remaining delay budget of the data packet of the first LCG is within the remaining delay budget range [5, 8), the PDCP layer of the terminal can send the remaining delay budget range [5, 8) corresponding to the data packet and / or the delay status information pair 2 corresponding to the remaining delay budget range of the data packet to the RLC layer of the terminal, with the sequence number "2".

[0111] In some embodiments of this application, the communication method provided in the embodiments of this application may further include the following step 401.

[0112] It should be noted that the terminal can execute step 401 below after executing step 301.

[0113] Step 401: When the remaining delay budget range corresponding to the data packet changes, the PDCP layer of the terminal sends the third delay-related information to the RLC layer of the terminal.

[0114] In the embodiments of this application, the aforementioned third delay-related information includes at least one of the following:

[0115] The revised remaining latency budget range corresponding to the data packet;

[0116] The sequence number of the changed remaining delay budget range corresponding to the data packet;

[0117] The sequence number of the delay status information pair corresponding to the changed remaining delay budget range of the data packet.

[0118] It is understandable that as time goes by, the remaining latency budget of a data packet will change, which will cause the range of the remaining latency budget corresponding to the data packet to change. When the range of the remaining latency budget corresponding to the data packet changes, the PDCP layer of the terminal can send the relevant information about the changed latency of the data packet to the RLC layer of the terminal.

[0119] It should be noted that for the detailed steps regarding the third delay-related information mentioned above, please refer to the description of the delay-related information corresponding to the data packets in the above embodiments, which will not be repeated here.

[0120] In some embodiments of this application, step 301 described above can be implemented by step 301b described below.

[0121] Step 301b: If the remaining delay budget of the data packet with the smallest remaining delay budget in the first LCG is less than or equal to the first preset threshold, the PDCP layer of the terminal sends delay-related information to the RLC layer of the terminal.

[0122] In the embodiments of this application, the first preset threshold value is the remaining latency budget threshold used to trigger the latency status information reporting of the first LCG.

[0123] In some embodiments of this application, triggering the delay status information report of the first LCG can be understood as triggering the DSR report of the first LCG.

[0124] It is understandable that as time goes by, the remaining latency budget of data packets will change continuously, causing the range of the remaining latency budget corresponding to the data packets to also change continuously. In order to avoid frequently sending the changed latency-related information of data packets from the PDCP layer to the RLC layer, the terminal's PDCP layer can send the latency-related information of data packets to the terminal's RLC layer only after triggering DSR reporting.

[0125] In some embodiments of this application, the PDCP layer of the terminal can send the latency-related information of the data packet to the RLC layer of the terminal when the MAC layer of the terminal generates the DSR of the first LCG.

[0126] Thus, since the terminal's PDCP layer only sends the latency-related information of the data packet to the terminal's RLC layer after triggering the DSR report, it can avoid the terminal's PDCP layer frequently sending the changed latency-related information of the data packet to the RLC layer when the remaining latency budget range corresponding to the data packet keeps changing, thereby saving the terminal's power consumption.

[0127] In some embodiments of this application, after the terminal's RLC layer generates the DSR of the first LCG based on the changed latency-related information corresponding to the data packet, the latency-related information corresponding to the data packet previously received by the terminal's RLC layer becomes invalid.

[0128] In some embodiments of this application, the data packet includes a first data packet and a second data packet, and the latency-related information includes a first latency-related information and a second latency-related information, wherein the first latency-related information corresponds to the first data packet and the second latency-related information corresponds to the second data packet.

[0129] In some embodiments of this application, the aforementioned first delay-related information includes at least one of the following:

[0130] The first remaining delay budget range corresponding to the first data packet;

[0131] The sequence number of the first remaining delay budget range corresponding to the first data packet;

[0132] The sequence number of the delay status information pair corresponding to the first data packet;

[0133] In some embodiments of this application, the aforementioned second delay-related information includes at least one of the following:

[0134] The second remaining delay budget range corresponding to the second data packet;

[0135] The sequence number of the second remaining delay budget range corresponding to the second data packet;

[0136] The sequence number of the delay status information pair corresponding to the second data packet.

[0137] It should be noted that for the detailed steps regarding the first and second delay-related information, please refer to the description of the delay-related information corresponding to the data packets in the above embodiments, which will not be repeated here.

[0138] In some embodiments of this application, the first data volume includes: the data volume corresponding to the first remaining latency budget range and the data volume corresponding to the second remaining latency budget range; the above step 202 can be specifically implemented by the following step 202a.

[0139] Step 202a: The terminal's RLC layer calculates the amount of data corresponding to the first remaining latency budget range based on the first latency-related information and the first data packet, and calculates the amount of data corresponding to the second remaining latency budget range based on the second latency-related information and the second data packet.

[0140] In some embodiments of this application, the first data packet and the second data packet are data packets of the first LCH of the first LCG, and the transmission position of the second data packet on the first LCH is located before the transmission position of the first data packet on the first LCH; the "the RLC layer of the terminal calculates the amount of data corresponding to the first remaining delay budget range based on the first delay-related information and the first data packet" in step 202a above can be specifically implemented by step 202b below.

[0141] Step 202b: If the second data packet satisfies the first condition, the terminal's RLC layer includes the data volume of the second data packet in the data volume corresponding to the first remaining delay budget range.

[0142] In the embodiments of this application, the first condition mentioned above includes at least one of the following:

[0143] The second data packet does not contain corresponding latency-related information from the PDCP layer;

[0144] The terminal's RLC layer did not receive the second delay-related information corresponding to the second data packet from the terminal's PDCP layer;

[0145] The terminal's RLC layer receives second latency-related information from the terminal's PDCP layer. The second latency-related information includes the fact that the lower limit of the second remaining latency budget range corresponding to the second data packet is greater than the upper limit of the first remaining latency budget range corresponding to the first data packet.

[0146] The terminal's RLC layer receives the second delay-related information from the terminal's PDCP layer. The second delay-related information includes the sequence number of the second remaining delay budget range corresponding to the second data packet being greater than the sequence number of the first remaining delay budget range corresponding to the first data packet.

[0147] The RLC layer of the terminal receives the second delay-related information from the PDCP layer of the terminal. The second delay-related information includes a delay status information pair corresponding to the second data packet whose sequence number is greater than the delay status information pair corresponding to the first data packet.

[0148] In some embodiments of this application, the absence of corresponding delay-related information from the PDCP layer in the second data packet can be divided into two cases: Case 1: The RLC layer of the terminal does not receive the second delay-related information corresponding to the second data packet from the PDCP layer of the terminal; Case 2: The data packet type of the second data packet is any of the following: RLC control PDU, RLC status PDU, retransmission RLC PDU in RLCAM mode, PDCP control PDU, PDCP status PDU.

[0149] It is understandable that if the second data packet does not have corresponding delay-related information from the PDCP layer, and the transmission position of the second data packet on the first LCH is before the transmission position of the first data packet on the first LCH, the terminal's RLC layer can include the data volume of both the first data packet and the data volume of the second data packet in the data volume corresponding to the first remaining delay budget range.

[0150] It is understandable that network-side devices allocate resources based on the data volume corresponding to the first remaining latency budget range reported by the terminal. When the terminal's RLC layer does not include the data volume of the second data packet in the data volume corresponding to the first remaining latency budget range, the resources allocated by the network-side devices will also decrease accordingly. Furthermore, since the transmission position of the second data packet on the first LCH precedes that of the first data packet, the second data packet will be allocated resources before the first data packet. Therefore, it is possible that after the second data packet is transmitted, the resources allocated by the network-side devices are insufficient, preventing the timely transmission of the first data packet. The solution in this application includes the data volumes of both the first and second data packets in the data volume corresponding to the first remaining latency budget range, allowing the network-side devices to allocate sufficient resources for transmitting the data packets corresponding to the first remaining latency budget range. This means transmitting the data packets corresponding to the latency status information pairs within the first remaining latency budget range, preventing data packets from being dropped due to delayed transmission.

[0151] In some embodiments of this application, when the lower limit of the remaining delay budget range corresponding to the second data packet is greater than the upper limit of the first remaining delay budget range corresponding to the first data packet, and the transmission position of the second data packet on the first LCH is before the transmission position of the first data packet on the first LCH, the RLC layer of the terminal can include the data volume of the first data packet and the data volume of the second data packet in the data volume corresponding to the first remaining delay budget range.

[0152] Example 2, combined with Example 1, such as Figure 4 As shown, assuming the data packets of the first LCH included in the first LCG, which are transmitted from the terminal's PDCP layer to the terminal's RLC layer, are data packets 1 to 11, the remaining delay budget for data packet 1 is 0ms, the remaining delay budget for data packet 2 is 1ms, the remaining delay budget for data packet 3 is 2ms, the remaining delay budget for data packet 4 is 4ms, the remaining delay budget for data packet 5 is 6ms, the remaining delay budget for data packet 6 is 9ms, the remaining delay budget for data packet 7 is 9ms, and the remaining delay budget for data packet 8 is 7ms, data... The remaining delay budget for packet 9 is 9ms, the remaining delay budget for packet 10 is 12ms, and the remaining delay budget for packet 11 is 11ms. The remaining delay budgets for packets 1 to 4 are within the remaining delay budget range (0,5) of delay status information pair 1. The remaining delay budgets for packets 5, 6, and 8 are within the remaining delay budget range [5,8) of delay status information pair 2. The remaining delay budgets for packets 7 and packets 9 to 11 are within the remaining delay budget range [8,∞) of delay status information pair 3.

[0153] When the second delay-related information includes the remaining delay budget range (i.e., the second remaining delay budget range mentioned above) corresponding to data packet 7 (i.e., the second data packet mentioned above) being [8,∞), and the terminal's RLC layer determining, based on the remaining delay budget range [8,∞) corresponding to data packet 7, that the lower limit of the remaining delay budget range [8,∞) corresponding to data packet 7 is greater than the upper limit of the remaining delay budget range [5,8) corresponding to data packet 8 (i.e., the first data packet mentioned above) [5,8), and the transmission position of data packet 7 on the first LCH is before the transmission position of data packet 8 on the first LCH, the terminal's RLC layer can include both the data volume of data packet 7 and the data volume of data packet 8 in the data volume corresponding to the remaining delay budget range [5,8) when calculating the data volume corresponding to the remaining delay budget range [5,8).

[0154] In some embodiments of this application, when the RLC layer of the terminal receives second delay-related information from the PDCP layer of the terminal, and the sequence number of the second remaining delay budget range corresponding to the second data packet included in the second delay-related information is greater than the sequence number of the first remaining delay budget range corresponding to the first data packet, and the transmission position of the second data packet on the first LCH is before the transmission position of the first data packet on the first LCH, the RLC layer of the terminal can include the data volume of the first data packet and the data volume of the second data packet in the data volume corresponding to the first remaining delay budget range.

[0155] Example 3, combined with Example 2, such as Figure 4 As shown, when the second delay-related information includes the sequence number "3" of the remaining delay budget range [8,∞) corresponding to data packet 7, and the first delay-related information includes the sequence number "2" of the remaining delay budget range [5,8) corresponding to data packet 8, and the transmission position of data packet 7 on the first LCH is before the transmission position of data packet 8 on the first LCH, the RLC layer of the terminal can include both the data volume of data packet 7 and the data volume of data packet 8 in the data volume corresponding to the remaining delay budget range [5,8) when calculating the data volume.

[0156] In some embodiments of this application, when the lower limit of the remaining delay budget range corresponding to the second data packet is greater than the upper limit of the first remaining delay budget range corresponding to the first data packet, the sequence number of the delay status information pair corresponding to the second data packet is also greater than the sequence number of the delay status information pair corresponding to the first data packet.

[0157] In some embodiments of this application, when the RLC layer of the terminal receives the second delay-related information from the PDCP layer of the terminal, and the sequence number of the delay status information pair corresponding to the second data packet included in the second delay-related information is greater than the sequence number of the delay status information pair corresponding to the first data packet, and the transmission position of the second data packet on the first LCH is before the transmission position of the first data packet on the first LCH, the RLC layer of the terminal can include the data volume of the first data packet and the data volume of the second data packet in the data volume corresponding to the first remaining delay budget range.

[0158] Example 4, combined with Example 2, such as Figure 4 As shown, assuming the remaining delay budgets of data packets 1 to 4 are within the remaining delay budget range (0, 5), then the delay status information pair corresponding to data packets 1 to 4 is 1; the remaining delay budgets of data packets 5, 6, and 8 are within the remaining delay budget range [5, 8), then the delay status information pair corresponding to data packets 5, 6, and 8 is 2; the remaining delay budgets of data packets 7 and 9 to 11 are within the remaining delay budget range [8, ∞), then the delay status information pair corresponding to data packets 7 and 9 to 11 is 3.

[0159] When the second delay-related information includes the sequence number "3" of delay status information pair 3 corresponding to data packet 7, and the first delay-related information includes the sequence number "2" of delay status information pair 2 corresponding to data packet 8, and the transmission position of data packet 7 on the first LCH is before the transmission position of data packet 8 on the first LCH, the RLC layer of the terminal can include both the data volume of data packet 7 and the data volume of data packet 8 in the data volume corresponding to the remaining delay budget range [5,8) when calculating the data volume.

[0160] It is understandable that network-side devices allocate resources based on the amount of data reported by the terminal. If the data volume of data packet 7 is not included in the remaining delay budget range [5,8), the resources allocated by the network-side devices will be reduced accordingly. Therefore, it is possible that after transmitting data packet 7, the resources allocated by the network-side devices are insufficient, and data packet 8 cannot be transmitted in time. By including the data volume of both data packet 7 and data packet 8 in the remaining delay budget range [5,8) of this application, the network-side devices can allocate sufficient resources for transmitting the data packets corresponding to delay status information pair 2, avoiding the possibility of data packets being dropped due to failure to be transmitted in time.

[0161] In some embodiments of this application, when the first data packet includes data packets in the first PDU set of the first LCH, and the transmission position of the second data packet on the first LCH is between the transmission positions of data packets in the first PDU set, the RLC layer of the terminal can include the data volume of the second data packet in the data volume corresponding to the first remaining delay budget range.

[0162] It is understandable that if the data volume of a PDU set in the first LCH should be included in the data volume corresponding to the first remaining delay budget range, then the other data packets sandwiched between the first and last data packets to be transmitted in that PDU set (i.e., the aforementioned second data packet) should also be included in the data volume corresponding to the first remaining delay budget range. This is because the receiving end processes data information as a whole, and the wireless network should transmit the PDU set as a whole as much as possible. Including the data packets sandwiched between data packets in a PDU set in the data volume corresponding to the same remaining delay budget range, i.e., the data volume corresponding to the same delay status information pair, is beneficial for the network-side device to allocate wireless resources based on the data volume of the delay status information pair, thus transmitting the complete PDU set to the receiving end.

[0163] In some embodiments of this application, step 202 described above can be implemented by step 202c or step 202d as described below.

[0164] Step 202c: Based on latency-related information and data packets, the terminal's RLC layer counts the amount of data corresponding to the first remaining latency budget range and the amount of data corresponding to the second remaining latency budget range in ascending order of the sequence number of the remaining latency budget range or the sequence number of the latency status information pair corresponding to the remaining latency range.

[0165] Example 5, combined with Example 3, such as Figure 4As shown, since the sequence number "2" corresponding to the remaining delay budget range [5,8) is less than the sequence number "3" corresponding to the remaining delay budget range [8,∞), the terminal's RLC layer can first count the amount of data corresponding to the remaining delay budget range [5,8), i.e., the amount of data corresponding to delay status information pair 2. Taking the first delay-related information received by the terminal's RLC layer as including the sequence number "2" of delay status information pair 2 corresponding to data packet 8, and the second delay-related information as including the sequence number "3" of delay status information pair 3 corresponding to data packet 7, the terminal's RLC layer can include the amount of data packet 8 in the amount of data corresponding to delay status information pair 2 based on the first delay-related information. Furthermore, since the sequence number of delay status information pair 3 corresponding to data packet 7 is greater than the sequence number of delay status information pair 2, and the transmission position of data packet 7 on the first LCH is before the transmission position of data packet 8 on the first LCH, the terminal's RLC layer can also include data packet 7 in the amount of data corresponding to delay status information pair 2. Then the terminal's RLC layer can calculate the amount of data corresponding to the remaining latency budget range [8,∞), that is, the data packets 9 to 11 are included in the amount of data corresponding to latency status information pair 3.

[0166] It's understandable that if the terminal's RLC layer counts the data volume corresponding to the first and second remaining latency budget ranges sequentially from largest to smallest, based on the remaining latency budget range number, some data with shorter remaining latency budgets may not be transmitted in a timely manner. For example... Figure 4 As shown, according to the remaining delay budget of data packet 8, the data volume of data packet 8 should be included in the data volume corresponding to delay status information pair 2. However, if the terminal's RLC layer first counts the data volume corresponding to delay status information pair 3, since the remaining delay budgets of data packets 11 and 7 are both within the remaining delay budget range [8,∞) corresponding to delay status information pair 3, the data volumes of data packets 7 to 11 will be included in the data volume corresponding to delay status information pair 3, resulting in data packet 8 not being transmitted in time.

[0167] Thus, since the terminal's RLC layer can count the data volume corresponding to the first remaining delay budget range and the data volume corresponding to the second remaining delay budget range in ascending order of the remaining delay budget range number, it can ensure that the data volume of data packets with longer remaining delay budgets interspersed between data packets with shorter remaining delay budgets is included in the data volume corresponding to the delay status information pair of the data packets with shorter remaining delay budgets. This is beneficial for network-side devices to allocate radio resources in a timely manner for the transmission of data with shorter remaining delay budgets.

[0168] Step 202d: Based on latency-related information and data packets, the terminal's RLC layer calculates the amount of data corresponding to the first remaining latency budget range, and then calculates the amount of data corresponding to the second remaining latency budget range.

[0169] In the embodiments of this application, the upper limit of the first remaining delay budget range is less than the lower limit of the second remaining delay budget range.

[0170] For example, the first remaining latency budget range is [5, 8), and the second remaining latency budget range is [8, ∞). The upper limit of the first remaining latency budget range [5, 8) is less than the lower limit of the second remaining latency budget range [8, ∞). Therefore, the terminal's RLC layer can first count the amount of data corresponding to the first remaining latency budget range, and then count the amount of data corresponding to the second remaining latency budget range.

[0171] In some embodiments of this application, the upper limit of the first remaining delay budget range is less than the lower limit of the second remaining delay budget range, which is equivalent to the sequence number of the first remaining delay budget range being less than the sequence number of the second remaining delay budget range, and the sequence number of the delay state information pair corresponding to the first remaining delay budget range being less than the sequence number of the delay state information pair corresponding to the second remaining delay budget range.

[0172] Thus, since the upper limit of the first remaining delay budget range is less than the lower limit of the second remaining delay budget range, the terminal's RLC layer can first count the data volume corresponding to the first remaining delay budget range and then count the data volume corresponding to the second remaining delay budget range. Therefore, it can be ensured that the data volume of data packets with longer remaining delay budgets interspersed between data packets with shorter remaining delay budgets is included in the data volume corresponding to the remaining delay budget range of the data packets with shorter remaining delay budgets. In other words, it can be ensured that the data volume of data packets with longer remaining delay budgets interspersed between data packets with shorter remaining delay budgets is included in the data volume corresponding to the delay status information pair of the data packets with shorter remaining delay budgets. This is beneficial for network-side devices to allocate radio resources in a timely manner for the transmission of data with shorter remaining delay budgets.

[0173] In some embodiments of this application, the first LCG corresponds to at least one delay state information pair, and the remaining delay budget range corresponding to at least one delay state information pair includes the remaining delay budget range corresponding to the data packet; the upper limit of the remaining delay budget range corresponding to the data packet is less than the lower limit of the third remaining delay budget range, and the third remaining delay budget range is any remaining delay budget range other than the remaining delay budget range corresponding to at least one delay state information pair; the above step 202 can be specifically implemented by the following step 202e.

[0174] Step 202e: The terminal's RLC layer includes the data volume of the third data packet in the first data volume.

[0175] In the embodiments of this application, the data packet type of the aforementioned third data packet includes any of the following: RLC control PDU, RLC status PDU, RLC retransmission RLC PDU in RLC AM mode, PDCP control PDU, and PDCP status PDU.

[0176] It can be understood that the remaining delay budget range corresponding to the data packet is the smallest remaining delay budget range among the remaining delay budget ranges corresponding to at least one delay state information pair.

[0177] It is understandable that when the terminal's RLC layer counts the first data volume, it can include the data volume of the aforementioned third data packet in the first data volume.

[0178] It is understandable that after the terminal obtains uplink transmission permission, the third data packet is given priority in allocating radio resources. This means the third data packet will receive radio resources before the data packet corresponding to the latency state information pair with the smallest remaining latency budget. To ensure that the network-side device allocates sufficient radio resources in a timely manner for the data packets corresponding to the latency state information pairs with the smallest remaining latency budget (i.e., the latency state information pairs corresponding to the remaining latency budget range of the aforementioned data packets), the third data packet can be included in the data volume corresponding to the latency state information pair with the smallest remaining latency budget. In other words, the third data packet is included in the aforementioned first data volume. This ensures that when the network-side device allocates uplink resources based on the data volume corresponding to the latency state information pair with the smallest remaining latency budget, the allocated radio resources are sufficient to cover the transmission of the data packets corresponding to the latency state information pair with the smallest remaining latency budget after allocating resources for the third data packet. It is also understandable that if the third data packet is included in the data volume corresponding to the latency state information pair with the largest remaining latency budget, the network-side device may not allocate uplink transmission resources in a timely manner, resulting in the data in the third data packet with the shorter remaining latency budget being discarded and not transmitted in time.

[0179] In some embodiments of this application, the communication method provided in the embodiments of this application may further include the following steps 501 and 502.

[0180] It should be noted that the terminal may execute step 501 before executing step 301, or execute step 501 after executing step 301. This application embodiment does not limit this.

[0181] Step 501: The terminal's PDCP layer calculates the second data volume corresponding to the remaining latency budget range based on the data cached by the PDCP layer.

[0182] It is understandable that the PDCP layer of the terminal can calculate the amount of data corresponding to each remaining latency budget range based on the data of the first LCG that has not been submitted to the RLC layer by the PDCP layer, that is, calculate the amount of data corresponding to each latency state information pair of the first LCG.

[0183] Step 502: The terminal generates latency status information corresponding to the remaining latency budget range based on the first data volume and the second data volume.

[0184] Specifically, the terminal can calculate the sum of the first data volume and the second data volume, and then generate latency status information corresponding to the remaining latency budget range based on the sum of the first data volume and the second data volume, and the remaining latency budget of the data packet with the smallest remaining latency budget corresponding to the remaining latency budget range.

[0185] In some embodiments of this application, the terminal can generate latency status information corresponding to each remaining latency budget range of the first LCG in order to generate and report the DSR of the first LCG.

[0186] Thus, since the PDCP layer and RLC layer can respectively calculate the amount of data corresponding to the remaining latency budget range, the terminal can obtain accurate data amount information corresponding to the remaining latency budget range. This allows the terminal to accurately reflect the radio resources required for the corresponding data transmission to complete the time slot information, so that the network-side equipment can accurately determine the amount of radio resources to be allocated to complete the data transmission corresponding to the remaining latency budget range.

[0187] In some embodiments of this application, the latency budget range includes a first remaining latency budget range and a second remaining latency budget range; the above step 501 can be specifically implemented by the following steps 501a or 501b.

[0188] Step 501a: The terminal's PDCP layer, based on the data cached by the PDCP layer, calculates the amount of data corresponding to the first remaining latency budget range and the amount of data corresponding to the second remaining latency budget range in ascending order of the sequence number of the remaining latency budget range or the sequence number of the latency status information pair corresponding to the remaining latency budget range.

[0189] For example, if the sequence number of the latency status information pair corresponding to the first remaining latency budget range is "2" and the sequence number of the latency status information pair corresponding to the second remaining latency budget range is "3", then the terminal's RLC layer can first count the amount of data corresponding to the first remaining latency budget range and then count the amount of data corresponding to the second remaining latency budget range.

[0190] Thus, since the PDCP layer of the terminal can count the amount of data corresponding to the first remaining delay budget range and the amount of data corresponding to the second remaining delay budget range in ascending order according to the sequence number of the remaining delay budget range or the sequence number of the delay status information pair corresponding to the remaining delay budget range, it can ensure that the amount of data of data packets with longer remaining delay budgets interspersed between data packets with shorter remaining delay budgets is included in the amount of data corresponding to the remaining delay budget range of the data packets with shorter remaining delay budgets. This is beneficial for network-side devices to allocate radio resources in a timely manner for the transmission of data with shorter remaining delay budgets.

[0191] It should be noted that, for the data cached by the PDCP layer of the terminal, the detailed steps for counting the data volume corresponding to the first remaining latency budget range and the second remaining latency budget range in ascending order of the sequence number of the remaining latency budget range or the sequence number of the latency status information pair corresponding to the remaining latency budget range can be found in step 202c above. The detailed steps for counting the data volume corresponding to the first remaining latency budget range and the second remaining latency budget range in ascending order of the sequence number of the remaining latency budget range or the sequence number of the latency status information pair corresponding to the remaining latency range are not repeated here.

[0192] Step 501b: Based on the information in the data packets, the PDCP layer of the terminal calculates the amount of data corresponding to the first remaining latency budget range and then calculates the amount of data corresponding to the second remaining latency budget range.

[0193] In the embodiments of this application, the upper limit of the first remaining delay budget range is less than the lower limit of the second remaining delay budget range.

[0194] Thus, since the upper limit of the first remaining latency budget range is less than the lower limit of the second remaining latency budget range, the PDCP layer of the terminal can first count the amount of data corresponding to the first remaining latency budget range, and then count the amount of data corresponding to the second remaining latency budget range. Therefore, it can be ensured that the amount of data of data packets with longer remaining latency budgets interspersed between data packets with shorter remaining latency budgets is included in the amount of data corresponding to the remaining latency budget range of the data packets with shorter remaining latency budgets. This is beneficial for network-side devices to allocate radio resources in a timely manner for the transmission of data with shorter remaining latency budgets.

[0195] It should be noted that, for the terminal's PDCP layer, based on data packet information, after calculating the data volume corresponding to the first remaining latency budget range, the detailed steps for calculating the data volume corresponding to the second remaining latency budget range after calculating the data volume corresponding to the first remaining latency budget range can be found in step 202d above. The detailed steps for the terminal's RLC layer, based on latency-related information and data packets, after calculating the data volume corresponding to the first remaining latency budget range, are not repeated here.

[0196] In some embodiments of this application, the first LCG corresponds to at least one delay state information pair, and the remaining delay budget range corresponding to at least one delay state information pair includes the remaining delay budget range corresponding to the data packet; the upper limit of the remaining delay budget range corresponding to the data packet is less than the lower limit of the third remaining delay budget range, and the third remaining delay budget range is any remaining delay budget range other than the remaining delay budget range corresponding to at least one delay state information pair; the above step 501 can be specifically implemented by the following step 501c.

[0197] Step 501c: The terminal's PDCP layer includes the data volume of the fourth data packet in the second data volume.

[0198] In the embodiments of this application, the fourth data packet includes at least one of the following: PDCP control PDU and PDCP status PDU.

[0199] It is understandable that when the terminal's PDCP layer is counting the second data volume, it can include the data volume of the aforementioned fourth data packet in the second data volume.

[0200] It is understandable that after the terminal obtains uplink transmission permission, the fourth data packet is given priority in allocating radio resources. In other words, the fourth data packet will receive radio resources before the data packet corresponding to the latency state information pair with the smallest remaining latency budget. In order to ensure that the network-side device allocates sufficient radio resources in a timely manner for the data packet corresponding to the latency state information pair with the smallest remaining latency budget, the fourth data packet can be counted in the data volume of the latency state information pair with the smallest remaining latency budget. That is, the fourth data packet is counted in the second data volume mentioned above. This way, when the network-side device allocates uplink resources based on the data volume of the latency state information pair with the smallest remaining latency budget, the allocated radio resources are sufficient to have enough remaining resources for the transmission of the data packet corresponding to the latency state information pair with the smallest remaining latency budget after allocating resources for the fourth data packet.

[0201] It should be noted that when the terminal's first LCG is configured to report multiple delay status information pairs, for each delay-critical data packet of each LCH within that first LCG, the terminal's PDCP layer no longer sends a delay-critical indication to the terminal's RLC layer. This is because the RLC layer will calculate the corresponding data volume for each delay status information pair based on the multiple remaining delay budget thresholds, and no longer needs to calculate the delay-critical data volume of the first LCG based on the delay-critical indication. In other words, when the first LCG is configured to report DSR but not to report multiple delay status information pairs, the terminal's PDCP layer needs to send a delay-critical indication to the terminal's RLC layer for each delay-critical data packet of each LCH within that first LCG.

[0202] Figure 5 A flowchart illustrating the communication method provided in the embodiments of this application is shown below. Figure 5 As shown, the communication method may include the following steps 601 and 602.

[0203] Step 601: The PDCP layer of the terminal receives information about the data packets from the RLC layer of the terminal.

[0204] In the embodiments of this application, the above-mentioned data packet is a data packet of the first LCG that is transmitted from the PDCP layer to the RLC layer, and the information of the data packet includes: the data packet sequence number and the data volume of the data packet.

[0205] It is understandable that after the data packet is passed from the terminal's PDCP layer to the terminal's RLC layer, the terminal's PDCP layer can receive the information of the data packet.

[0206] In some embodiments of this application, the communication method provided in the embodiments of this application may further include the following step 701.

[0207] It should be noted that the terminal may execute step 701 before executing step 601.

[0208] Step 701: The terminal's RLC layer sends data packet information to the terminal's PDCP layer.

[0209] It is understandable that after the data packet is transmitted from the terminal's PDCP layer to the terminal's RLC layer, the terminal's RLC layer can send the data packet information to the terminal's PDCP layer.

[0210] In some embodiments of this application, the RLC layer of the terminal may send data packet information to the PDCP layer of the terminal upon receiving a first request information from the PDCP layer of the terminal.

[0211] In some embodiments of this application, the first request information is used to request the RLC layer of the terminal to send information about data packets that are passed from the PDCP layer to the RLC layer to the PDCP layer of the terminal.

[0212] In some embodiments of this application, step 701 described above can be implemented by step 701a as follows.

[0213] Step 701a: If the remaining delay budget of the data packet with the smallest remaining delay budget in the first LCG is less than or equal to the first preset threshold, the RLC layer of the terminal sends the data packet information to the PDCP layer of the terminal.

[0214] In the embodiments of this application, the first preset threshold value is the remaining latency budget threshold used to trigger the latency status information reporting of the first LCG.

[0215] In some embodiments of this application, triggering the delay status information report of the first LCG can be understood as triggering the DSR report of the first LCG.

[0216] In some embodiments of this application, the RLC layer of the terminal may send data packet information to the PDCP layer of the terminal when the MAC layer of the terminal generates the DSR of the first LCG.

[0217] Thus, since the terminal's RLC layer can also send data packet information to the terminal's PDCP layer after triggering DSR reporting, the flexibility of the terminal's RLC layer in sending data packet information that has been passed from the PDCP layer to the RLC layer to the terminal's PDCP layer is improved.

[0218] Step 602: The terminal's PDCP layer counts the third data volume based on the information in the data packets.

[0219] In the embodiments of this application, the third data volume is the data volume corresponding to the remaining latency budget range of the data packet.

[0220] It is understandable that after the terminal's PDCP layer receives the information of the data packet, it can determine the remaining delay budget range corresponding to the data packet based on the remaining delay budget of the data packet. Then, when counting the amount of data corresponding to the remaining delay budget range of the data packet, the amount of data of the data packet can be included in the third data volume.

[0221] This application provides a communication method. Since the PDCP layer of the terminal can receive the data packet information after the data packet of the first LCG is transmitted to the RLC layer by the PDCP layer, the PDCP layer of the terminal can include the data packet data amount in the third data amount based on the data packet information when the PDCP layer of the terminal counts the third data amount corresponding to the remaining delay budget range of the data packet. This allows the terminal to generate the delay status information corresponding to the remaining delay budget range, i.e. the delay status information of the first LCG, based on the third data amount.

[0222] In some embodiments of this application, the data packet includes a first data packet and a second data packet, and the information of the data packet includes: the information of the first data packet and the information of the second data packet. The remaining latency budget range includes a first remaining latency budget range and a second remaining latency budget range. The first data packet corresponds to the first remaining latency budget range, and the second data packet corresponds to the second remaining latency budget range.

[0223] In some embodiments of this application, the third data volume includes: the data volume corresponding to the first remaining delay budget range and the data volume corresponding to the second remaining delay budget range; the above step 602 can be specifically implemented by the following step 602a.

[0224] Step 602a: The PDCP layer of the terminal calculates the amount of data corresponding to the first remaining latency budget range based on the information of the first data packet, and calculates the amount of data corresponding to the second remaining latency budget range based on the information of the second data packet.

[0225] In some embodiments of this application, the first data packet and the second data packet are data packets of the first LCH of the first LCG, and the transmission position of the second data packet on the first LCH is located before the transmission position of the first data packet on the first LCH; the "the PDCP layer of the terminal calculates the amount of data corresponding to the first remaining delay budget range based on the information of the first data packet" in the above step 602a can be specifically implemented by the following step 602b.

[0226] Step 602b: If the second data packet satisfies the second condition, the PDCP layer of the terminal includes the data volume of the second data packet in the data volume corresponding to the first remaining delay budget range.

[0227] In the embodiments of this application, the second condition mentioned above includes at least one of the following:

[0228] The second data packet does not have a corresponding remaining delay budget range;

[0229] The sequence number of the remaining delay budget range corresponding to the second data packet is greater than the sequence number of the first remaining delay budget range corresponding to the first data packet;

[0230] The lower limit of the remaining latency budget range corresponding to the second data packet is greater than the upper limit of the first remaining latency budget range corresponding to the first data packet.

[0231] In some embodiments of this application, when the data packet type of the second data packet is any of the following: PDCP control PDU, PDCP status PDU, the second data packet does not have a corresponding remaining delay budget range.

[0232] It is understandable that if the second data packet does not have a corresponding remaining delay budget range and the transmission position of the second data packet on the first LCH is before the transmission position of the first data packet on the first LCH, the PDCP layer of the terminal can include the data volume of the second data packet and the data volume of the first data packet in the data volume corresponding to the first remaining delay budget range.

[0233] It is understandable that network-side devices allocate resources according to the data volume corresponding to the first remaining latency budget range. When the terminal's PDCP layer does not include the data volume of the second data packet in the data volume corresponding to the first remaining latency budget range, the resources allocated by the network-side devices will also be reduced accordingly. Furthermore, since the transmission position of the second data packet on the first LCH precedes that of the first data packet, the second data packet will be allocated resources before the first data packet. Therefore, it is possible that after the second data packet is transmitted, the resources allocated by the network-side devices are insufficient, and the first data packet cannot be transmitted in time. The solution in this application includes the data volume of both the second and first data packets in the data volume corresponding to the first remaining latency budget range, allowing the network-side devices to allocate sufficient resources for transmitting the data packets corresponding to the latency status information pairs within the first remaining latency budget range, thus preventing data packets from being dropped due to failure to be transmitted in time.

[0234] In some embodiments of this application, when the sequence number of the remaining delay budget range corresponding to the second data packet is greater than the sequence number of the remaining delay budget range corresponding to the first data packet, and the transmission position of the second data packet on the first LCH is before the transmission position of the first data packet on the first LCH, the RLC layer of the terminal can include the data volume of the first data packet and the data volume of the second data packet in the data volume corresponding to the first remaining delay budget range.

[0235] In some embodiments of this application, when the lower limit of the remaining delay budget range of the second data packet is greater than the upper limit of the first remaining delay budget range corresponding to the first data packet, and the transmission position of the second data packet on the first LCH is before the transmission position of the first data packet on the first LCH, the RLC layer of the terminal can include both the data volume of the second data packet and the data volume of the first data packet in the data volume corresponding to the first remaining delay budget range.

[0236] In some embodiments of this application, the second condition may further include: the sequence number of the delay status information pair corresponding to the second data packet is greater than the sequence number of the delay status information pair corresponding to the first data packet.

[0237] In some embodiments of this application, when the lower limit of the remaining delay budget range of the second data packet is greater than the upper limit of the first remaining delay budget range corresponding to the first data packet, the sequence number of the delay status information pair corresponding to the second data packet is also greater than the sequence number of the delay status information pair corresponding to the first data packet.

[0238] In some embodiments of this application, when the sequence number of the delay state information pair corresponding to the second data packet is greater than the sequence number of the delay state information pair corresponding to the first data packet, and the transmission position of the second data packet on the first LCH is before the transmission position of the first data packet on the first LCH, the RLC layer of the terminal can include the data volume of the second data packet and the data volume of the first data packet in the data volume corresponding to the first remaining delay budget range.

[0239] It should be noted that, for the detailed steps of the terminal's PDCP layer including the data volume of the second data packet in the data volume corresponding to the first remaining delay budget range when the second data packet meets the second condition, please refer to the detailed description of the terminal's RLC layer including the data volume of the second data packet in the data volume corresponding to the first remaining delay budget range when the second data packet meets the first condition in step 202b above, which will not be repeated here.

[0240] In some embodiments of this application, step 602 described above can be implemented by step 602c or step 602d as described below.

[0241] Step 602c: Based on the information in the data packets, the PDCP layer of the terminal counts the amount of data corresponding to the first remaining delay budget range and the amount of data corresponding to the second remaining delay budget range in ascending order of the remaining delay budget range number.

[0242] In some embodiments of this application, the PDCP layer of the terminal can, based on the information of the data packets, also count the amount of data corresponding to the first remaining delay budget range and the amount of data corresponding to the second remaining delay budget range in ascending order of the sequence number of the delay status information pairs corresponding to the remaining delay budget range.

[0243] Example 6: Assuming the sequence number of the first remaining delay budget range is less than the sequence number of the second remaining delay budget range, the PDCP layer of the terminal can first count the amount of data corresponding to the first remaining delay budget range. Since the first data packet corresponds to the first remaining delay budget range, the PDCP layer of the terminal can include the data amount of the first data packet included in the information of the first data packet in the amount of data corresponding to the first remaining delay budget range. Then, if the transmission position of the second data packet on the first LCH is before the transmission position of the first data packet on the first LCH, the PDCP layer of the terminal can also include the data amount of the second data packet in the amount of data corresponding to the first remaining delay budget range. After counting the amount of data corresponding to the first remaining delay budget range, the PDCP layer of the terminal can count the amount of data corresponding to the second remaining delay budget range.

[0244] It is understandable that if the PDCP layer of the terminal counts the amount of data corresponding to the first remaining latency budget range and the second remaining latency budget range in descending order according to the sequence number of the remaining latency budget range, it will result in some data with short remaining latency budgets not being transmitted in time.

[0245] Thus, since the PDCP layer of the terminal can count the data volume corresponding to the first remaining delay budget range and the data volume corresponding to the second remaining delay budget range in ascending order of the remaining delay budget range number, it can ensure that the data volume of data packets with longer remaining delay budgets that are interspersed between data packets with shorter remaining delay budgets are included in the data volume corresponding to the remaining delay budget range of the data packets with shorter remaining delay budgets. This is beneficial for network-side devices to allocate radio resources in a timely manner for the transmission of data with shorter remaining delay budgets.

[0246] It should be noted that the detailed steps for the PDCP layer of the terminal to count the data volume corresponding to the first remaining delay budget range and the second remaining delay budget range in ascending order based on the information of the data packets can be found in step 202c above. The detailed steps for the RLC layer of the terminal to count the data volume corresponding to the first remaining delay budget range and the second remaining delay budget range in ascending order based on the information of the delay-related information and data packets, or the sequence number of the delay status information pair corresponding to the remaining delay range, are not repeated here.

[0247] Step 602d: Based on the information in the data packets, the PDCP layer of the terminal calculates the amount of data corresponding to the first remaining latency budget range, and then calculates the amount of data corresponding to the second remaining latency budget range.

[0248] In the embodiments of this application, the upper limit of the first remaining delay budget range is less than the lower limit of the second remaining delay budget range.

[0249] In some embodiments of this application, the upper limit of the first remaining delay budget range is less than the lower limit of the second remaining delay budget range, which is equivalent to the sequence number of the first remaining delay budget range being less than the sequence number of the second remaining delay budget range, and the sequence number of the delay state information pair corresponding to the first remaining delay budget range being less than the sequence number of the delay state information pair corresponding to the second remaining delay budget range.

[0250] Thus, since the upper limit of the first remaining latency budget range is less than the lower limit of the second remaining latency budget range, the PDCP layer of the terminal can first count the amount of data corresponding to the first remaining latency budget range, and then count the amount of data corresponding to the second remaining latency budget range. Therefore, it can be ensured that the amount of data of data packets with longer remaining latency budgets interspersed between data packets with shorter remaining latency budgets is included in the amount of data corresponding to the remaining latency budget range of the data packets with shorter remaining latency budgets. This is beneficial for network-side devices to allocate radio resources in a timely manner for the transmission of data with shorter remaining latency budgets.

[0251] It should be noted that, for the terminal's PDCP layer based on data packet information, after calculating the data volume corresponding to the first remaining latency budget range, the detailed steps for calculating the data volume corresponding to the second remaining latency budget range can be found in step 202d above, which describes in detail how the terminal's RLC layer, based on latency-related information and data packets, calculates the data volume corresponding to the second remaining latency budget range after calculating the data volume corresponding to the first remaining latency budget range. This will not be repeated here.

[0252] In some embodiments of this application, the first LCG corresponds to at least one delay state information pair, and the remaining delay budget range corresponding to at least one delay state information pair includes the remaining delay budget range corresponding to the data packet; the upper limit of the remaining delay budget range corresponding to the data packet is less than the lower limit of the fourth remaining delay budget range, and the fourth remaining delay budget range is any remaining delay budget range other than the remaining delay budget range corresponding to at least one delay state information pair; the above step 602 can be specifically implemented by the following step 602e.

[0253] Step 602e: The terminal's PDCP layer includes the data volume of the fifth data packet in the third data volume.

[0254] In the embodiments of this application, the data packet type of the fifth data packet mentioned above includes any one of the following: PDCP control PDU, PDCP status PDU.

[0255] It is understandable that when the terminal's PDCP layer is counting the third data volume, it can include the data volume of the aforementioned fifth data packet in the third data volume.

[0256] It is understandable that after the terminal obtains uplink transmission permission, the fifth data packet is given priority in allocating radio resources. In other words, the fifth data packet will receive radio resources before the data packet corresponding to the latency state information pair with the smallest remaining latency budget. In order to ensure that the network-side device allocates sufficient radio resources in a timely manner for the data packet corresponding to the latency state information pair with the smallest remaining latency budget, the fifth data packet can be included in the data volume corresponding to the latency state information pair with the smallest remaining latency budget. This way, when the network-side device allocates uplink resources based on the data volume corresponding to the latency state information pair with the smallest remaining latency budget, the allocated radio resources are sufficient to have enough remaining resources for the transmission of the data packet corresponding to the latency state information pair with the smallest remaining latency budget after allocating resources for the fifth data packet.

[0257] In some embodiments of this application, the communication method provided in the embodiments of this application may further include the following step 702.

[0258] It should be noted that the terminal can execute step 702 below after executing step 602.

[0259] Step 702: The terminal generates latency status information corresponding to the remaining latency budget range based on the third data volume.

[0260] In some embodiments of this application, the first LCG corresponds to at least one delay state information pair, and the remaining delay budget range corresponding to at least one delay state information pair includes the remaining delay budget range corresponding to the data packet; the upper limit of the remaining delay budget range corresponding to the data packet is less than the lower limit of the fourth remaining delay budget range, and the fourth remaining delay budget range is any remaining delay budget range other than the remaining delay budget range corresponding to at least one delay state information pair; the communication method provided in the embodiments of this application may further include the following step 801.

[0261] It should be noted that the terminal may execute step 801 before executing step 701; or, may execute step 801 after executing step 701.

[0262] Step 801: The terminal's RLC layer includes the data volume of the sixth data packet in the fourth data volume corresponding to the remaining delay budget range.

[0263] In the embodiments of this application, the data packet type of the sixth data packet mentioned above includes any one of the following: RLC control PDU, RLC status PDU, and RLC retransmission PDU in RLC AM mode.

[0264] In the embodiments of this application, the latency status information corresponding to the remaining latency budget range is generated by the terminal based on the third data volume and the fourth data volume.

[0265] It is understandable that the terminal's RLC layer not only sends the information of the data packets that are passed from the PDCP layer to the RLC layer to the terminal's PDCP layer, but also, for the special sixth data packet, the terminal's RLC layer needs to include the data volume of the sixth data packet in the fourth data volume corresponding to the remaining delay budget range.

[0266] In some embodiments of this application, the terminal can generate latency status information corresponding to the remaining latency budget range based on the third data volume corresponding to the remaining latency budget range statistically calculated by the terminal's PDCP layer and the fourth data volume corresponding to the remaining latency budget range statistically calculated by the terminal's RLC layer.

[0267] Specifically, the terminal can calculate the sum of the third and fourth data volumes, and then, based on the sum of the third and fourth data volumes and the remaining latency budget of the data packet with the smallest remaining latency budget within the remaining latency budget range, generate latency status information corresponding to the remaining latency budget range.

[0268] The communication method provided in this application can be executed by a communication device. This application uses the example of a communication device executing the communication method to illustrate the communication device provided in this application.

[0269] This application provides a communication device. As an example, the communication device may be a communication equipment or a component within a communication equipment, such as a chip. The communication equipment may be a terminal.
