[0024] Embodiments of the present disclosure provide a DSR transmission method, a communication device, a communication system, and a storage medium.

[0025] A first aspect of an embodiment of the present disclosure provides a delay status report DSR transmission method, which is executed by a user equipment UE and includes: there is at least one first type of data in a protocol data packet PDU set, and a delay status report DSR of the PDU set is sent to a network device; the PDU set also includes a second type of data; the remaining duration of the second type of data is greater than the remaining duration of the first type of data; the remaining duration of the second type of data is in a first interval; the first interval associated data volume of the DSR includes the data volume of the first type of data.

[0026] Based on the above solution, when the DSR for a PDU set is sent, the data will be divided into two categories according to the remaining duration of the data, and the data volume of the second category of data will be counted in the first interval, thereby solving the problem that the remaining durations of different PDUs in the PDU set are different, resulting in no statistical interval for the data volume of some PDUs.

[0027] In some embodiments of the first aspect, the remaining duration of the first category of data is less than a first threshold.

[0028] The above solution clearly defines the first category of data through the remaining time and the first threshold, and is easy to implement.

[0029] In some embodiments of the first aspect, the remaining duration of the second category of data is greater than or equal to a first threshold.

[0035] In some embodiments of the first aspect, the first interval is a time interval with a maximum value or a minimum value among the multiple time intervals.

[0036] In the above scheme, the first interval can specifically be a time interval with the largest or smallest value among multiple time intervals associated with the DSR. In this way, there is no need to additionally configure the first interval, which has the characteristic of simple implementation.

[0091] Figure 1A It is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0092] like Figure 1A As shown, the communication system 100 includes a terminal 101 and a network device 102. The network device 102 may include an access network device and / or a core network device. The terminal may also be referred to as a UE.

The CU-DU structure may be used to split the protocol layer of the access network device, with some functions of the protocol layer being centrally controlled by the CU, and the remaining part or all of the functions of the protocol layer being distributed in the DU, and the DU being centrally controlled by the CU, but not limited to this.

[0098] In some embodiments, the core network device may be a device including a first network element, etc., or may be a plurality of devices or a group of devices, each including a first network element. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0099] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical approach of the embodiment of the present disclosure, and does not constitute a limitation on the technical approach provided by the embodiment of the present disclosure. A person of ordinary skill in the art can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical approach provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0100] The following embodiments of the present disclosure can be applied to Figure 1A The communication system 100, or a portion thereof, is shown but is not limited thereto. Figure 1A The various entities shown are examples, and the communication system may include Figure 1A All or part of the subject, and may also include Figure 1A For entities other than the above, the number and form of each entity are arbitrary, and the connection relationship between the entities is an example. The entities may be connected or disconnected, and the connection may be in any manner, which may be direct or indirect, and may be wired or wireless.

[0101] The embodiments of the present disclosure may be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine-to-Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), systems using configuration methods of other resources, next-generation systems based on them, etc. In addition, multiple systems can also be combined (for example, a combination of LTE and NR).

[0102] By sending a BSR to the network device, the UE can request the network device to schedule the transmission of service data that the UE urgently needs to transmit or is about to time out. In some cases, the BSR can only be sent when high-priority logical channel data arrives, and the emergency scheduling needs cannot be met at this time. Therefore, it is necessary to consider optimizing the emergency scheduling situation in XR. The UE can report a Delay Status Report (DSR) to the network device, and the DSR carries delay information. For example, because a certain uplink data cannot be scheduled for a long time, resulting in the remaining time of its data packet being less than a certain threshold, the information and / or delay information of the uplink data is reported through the DSR. The remaining time of a data packet is the time difference between the current time and the time when the packet is discarded. Usually, the remaining time is determined according to the discard timer of the Packet Data Convergence Protocol (PDCP).

[0103] DSR is used by the UE to send the delay status information of the logical channel group (LCG) to the network device. The delay status information may include: the remaining time information of the LCG and the total amount of delay-critical uplink data to be sent by the LCG. The remaining time information indicates the minimum remaining time in the service data unit (SDU) that has not been transmitted by the PDCP.

[0104] Figure 1B A schematic diagram of a DSR is shown. Figure 1B The DSR shown includes an LCG field, a BT field, a remaining time (Remaining Time) field, and a buffer size (Buffer Size, BS) field.

[0105] The LCG field is used to indicate the LCG reported by the DSR. Exemplarily, if the indication bit corresponding to a certain channel in the LCG field takes a value of 1, it means that the DSR contains the delay status information of the LCG. If the indication bit corresponding to a certain channel in the LCG field takes a value of 0, it means that the DSR does not contain the delay status information of the LCG. In some embodiments, the delay status information may include the remaining duration information and / or BS value of the corresponding LCG.

[0106] The remaining time carries the remaining duration information, which is used to indicate the remaining duration. In the disclosed embodiment, the remaining duration may also be referred to as the remaining time. The remaining time may be the shortest remaining duration of the PDCP discard timer.

[0107] The Remaining Time field may be used to indicate the amount of data packets within a corresponding time interval, that is, the BS value.

[0108] The BT field indicates the table referenced by the BS value calculation. If the BT field is 1, it indicates that the calculated BS value of cache table 1 is used; if the BT field is 0, it indicates that the calculated BS value of cache table 2 is used.

[0109] The BT field and the remaining time and cache size fields of an LCG may be set in two octets that are continuously distributed.

[0110] A data packet may correspond to a protocol data unit (PDU). Multiple PDUs with an associated relationship may be organized into a PDU set. For example, the PDUs corresponding to different frames in the same video have a dependency relationship during decoding, and the PDUs of these frames can be set in the same PDU.

[0111] In another embodiment, in the extended reality (eXtended Reality, XR) service, the data is usually composed of multiple service quality flows (Quality of Service, QoS) flows), and its business volume is very large. The QoS flows included in the XR service may include audio streams, video streams, perception streams, etc. The XR service flow needs to meet certain latency requirements during the transmission process, especially some data streams need to arrive at the server at the same time for decoding. In order to ensure the correctness of data decoding, these data will be set to the same PDU set.

[0112] Regarding the transmission based on PDU sets, the delay of any data stream will cause the joint decoding of multiple data streams to fail. The network scheduling is dynamic, so in some cases, even if some data streams belong to low-priority logical channels, if some data packets have not been scheduled for a long time, a buffer report (BSR) needs to be sent to notify the network as soon as possible.

[0113] In view of this, if Figure 2 As shown, a DSR communication method is provided in an embodiment of the present disclosure, which can be used in a communication system 100, and the method includes:

[0114] S2101: The network device sends a network indication to the UE.

[0115] In some embodiments, the network device may be an access network device. Exemplarily, the access network device may include but is not limited to eNB and / or gNB, etc.

[0116] In some embodiments, the UE sends a Radio Resource Control (RRC) message, a Media Access Control (MAC) layer message, or a Downlink Control Information (DCI) including a network indication to a network device.

[0117] In some embodiments, the network indication may be information specifically indicating the first interval.

[0118] In some embodiments, the network indication may correspond to DSR configuration information, and the information indicating the first interval may be used as a type of DSR configuration information. In some embodiments, the DSR configuration information may include but is not limited to at least one of the following:

[0119] Types of DSRs;

[0120] Resource information of the DSR, which may indicate the frequency domain resources, time domain resources, channels, carrier components or beams for sending the DSR;

[0121] The data format of the DSR, for example, whether the data formats of the different types of DSRs are the same or different, for example, the data format of a specific DSR and a second type of DSR;

[0122] DSR message settings, for example, whether different types of DSR can be carried in the same MAC CE, or whether different types need to be reported through different MAC CEs;

[0123] Reporting method of the second type of data in DSR. For example, when DSR carries the second type of data, the reporting method can be used to indicate the time interval (ie, the first interval) corresponding to the amount of data of the second type of data packet.

[0124] In some embodiments, the DSR that can be configured by the DSR configuration information can be used to carry delay status information of a set of PDUs.

[0125] In some embodiments, the PDU may include first-category data and second-category data according to the size of the remaining duration. In some embodiments, the first-category data may also be referred to as delay critical data, while the second-category data is not delay critical data. In other embodiments, both the first-category data and the second-category data are delay critical data, but they are of different types.

[0126] In some embodiments, the remaining duration of the first category of data is less than the remaining duration of the second category of data.

[0127] In some embodiments, the remaining duration of the first category of data is less than a first threshold.

[0128] In some examples, the remaining duration of the second type of data is greater than or equal to the first threshold.

[0129] In some embodiments, the first threshold may be a dividing line between the first category of data and the second category of data.

[0130] In some embodiments, the first threshold may be a triggering threshold for triggering DSR reporting.

[0131] In some embodiments, the type of DSR can be divided into DSR and second type DSR according to the number of groups of delay state information that the DSR can carry for one LCG.

[0132] In an embodiment of the present disclosure, the delay status information may be information reflecting the remaining delay of the data to be transmitted. Exemplarily, the delay status information may include at least a BS value. The BS value is used to indicate the amount of data.

[0133] In some embodiments, the first type of DSR includes a set of delay status information. Exemplarily, for one LCG, the first type of DSR includes a set of delay status information.

[0134] In some embodiments, the second type DSR includes one or more groups of delay status information. Exemplarily, for one LCG, the second type DSR can carry one or more groups of delay status information. For one LCG, the number of groups of delay status information carried by the second type DSR depends on the time interval of the remaining duration distribution of the data packet corresponding to the LCG.

[0135] In some embodiments, one LCG may be associated with one or more PDU sets.

[0136] In some embodiments, the first type of DSR may be associated with a time interval, which may be between 0 and a first threshold. If the first type of DSR carries duration information, the duration information may be the minimum remaining duration, maximum remaining time, and average remaining time of data whose remaining duration is less than the first threshold. In order to save the signaling overhead of the first type of DSR, the first type of DSR may not carry duration information at this time.

[0137] In some other embodiments, the number of time intervals associated with the second type of DSR is greater than 1, that is, the number of time intervals associated with the second type of DSR is at least two. That is, the second type of DSR is associated with multiple time intervals. The value ranges of the remaining durations corresponding to these multiple time intervals are different.

[0138] In some embodiments, according to whether the first interval belongs to one of the multiple time intervals associated with the second type of DSR, there are two ways to determine the first interval:

[0139] Method 1:

[0140] The first interval is one of multiple time intervals associated with the second type DSR.

[0141] In some embodiments, the first interval may be a specific time interval of multiple time intervals associated with the second type of DSR. The specific time interval may be agreed upon by a protocol or indicated by a network device.

[0142] In some embodiments, the first interval is the time interval with the largest value or the smallest value among the multiple time intervals. If the first interval is set to be the time interval with the largest value among the multiple time intervals associated with the second type of DSR, the data volume of the second type of data will be counted in the BS value corresponding to the time interval with the largest value, so that the emergency situation of the resource scheduling of the current PDU set to be transmitted can be best reflected, and the network device can perform resource scheduling accurately and timely according to the second type of DSR as needed.

[0143] In this manner, the second-type DSR is associated with M time intervals for one LCG, and the second-type DSR carries at most M groups of delay status information of one LCG.

[0144] Method 2:

[0145] The first interval is different from any time interval of the multiple time intervals associated with the second type DSR.

[0146] In some embodiments, the value of the first interval is greater than the value of any time interval of the multiple time intervals.

[0147] In this case, for one LCG, the second type is associated with M time intervals, and the second type DSR carries at most M+1 groups of delay status information of one LCG.

[0148] In some embodiments, a set of delay status information may include remaining duration information and a BS value. The remaining duration information may be used to indicate the remaining duration. The BS value is the amount of data of the PDU whose remaining duration falls within the corresponding time zone.

[0149] In some embodiments, a set of delay status information may include an index value of a time interval and a BS value. The index value may indicate the index of the time interval where the remaining duration of the PDU is located.

[0150] In some other embodiments, a set of delay state information may include a BS value, and the multiple time intervals associated with the second type of DSR are sorted as needed. For example, the multiple time intervals are sorted from large to small or from small to large according to the corresponding remaining time lengths.

[0151] Of course, the above is only an example of the difference between DSR and the second type of DSR, and the specific implementation is not limited to the above example.

[0152] The following is an example of the association relationship between the DSR and the second type of DSR.

[0153] Association method 1: The second type of DSR can be regarded as a special form of DSR.

[0154] In this case, the reporting of the delay status information for the LCG may include at least one of the following characteristics:

[0155] The triggering events of the second type of DSR and DSR are the same;

[0156] For an LCG, the prerequisite for configuring the second type of DSR is to configure DSR; that is, for an LCG, DSR can be configured separately, or DSR and the second type of DSR can be configured at the same time. When an LCG is configured with both DSR and the second type of DSR, whether to use DSR or the second type of DSR can be indicated by the network, or confirmed according to the protocol agreement or negotiation with the network device. In some embodiments, the UE can also determine whether to use DSR or the second type of DSR according to the number of time intervals to which the remaining duration of the PDU that meets the triggering event of the LCG belongs. For example, if the remaining duration of the PDU that meets the triggering event of an LCG is distributed in a time interval, DSR can be used to report the delay status information of the LCG in priority to minimize unnecessary network signaling overhead. If the remaining duration of the PDU that meets the triggering event of an LCG is distributed in multiple time intervals, the second type of DSR can be used to report the delay status information of the LCG in priority, thereby achieving fine reporting.

[0157] In some embodiments, the trigger event may include but is not limited to: detecting that the remaining duration of at least one stored PDU of the corresponding LCG is less than a first threshold. In some embodiments, the first threshold may be used as the maximum remaining duration value of the time interval associated with the DSR and / or the second type of DSR.

[0158] In some embodiments, corresponding to association relationship 1, the prerequisite for the UE to support the second type of DSR is that the UE supports the DSR. Of course, in other embodiments, whether the UE supports the second type of DSR has nothing to do with whether the UE supports the DSR.

[0159] In some embodiments, corresponding to association relationship 1, the triggering events of DSR and the second type of DSR may be: there is at least one logical channel group LCG whose remaining duration is less than the first threshold.

[0160] Relationship 2: The second type of DSR and DSR are two different types of DSR in parallel.

[0161] In this case, the reporting of the delay status information for the LCG may include at least one of the following characteristics:

[0162] The triggering events of the second type DSR and DSR are set separately. In this case, the triggering events of the second type DSR and DSR may be the same or different. Whether they are the same depends on the specific settings of the triggering events of the DSR and the second type DSR.

[0163] For an LCG, DSR can be configured alone, the second type of DSR can be configured alone, and DSR and the second type of DSR can be configured simultaneously. The DSR configured for a specific LCG may depend on the configuration of the network device and / or the service attributes associated with the LCG, the urgency of the service data, and / or the Quality of Service (QoS).

[0164] In some embodiments, the capability information is used by the network device to determine whether the UE supports the second type of DSR.

[0165] In some embodiments, it is assumed that all UEs support DSR. In this case, when the UE supports the second type of DSR, it specifically indicates to the network device through capability information, while the UE that does not support the second type of DSR can carry information related to DSR reporting in different capability information, thereby saving at least part of the UE's bit overhead.

[0166] In some embodiments, corresponding to association relationship 2, whether the UE supports the second type of DSR has nothing to do with whether the UE supports the DSR. Of course, in some embodiments, even if corresponding to association relationship 2, the prerequisite for the UE to support the second type of DSR is that the UE supports the DSR.

[0167] If the prerequisite for the UE to support the second type of DSR is DSR, and the UE indicates support for the second type of DSR through capability information, it means that the UE must also support DSR.

[0168] If the UE supports the second type of DSR and whether it supports DSR, the UE indicates support for the second type of DSR through capability information, and whether the UE supports DSR needs to be additionally determined.

[0169] It is worth noting that: the operation of the network device sending the network indication can be performed separately. If the network device sends the network indication, but the UE does not detect the event that triggers the DSR report, the UE will not send the DSR, and the subsequent steps of the UE generating the DSR, sending the DSR, and the network device receiving and decoding the DSR will not occur. Alternatively, if the UE detects the event that triggers the DSR report, but the UE chooses to use the first type of DSR to send the delay status information, then the subsequent steps of the UE determining multiple time intervals associated with the second type and determining the first interval, etc., can be omitted.

[0170] In some embodiments, the operation of the network device sending the network device is an optional operation. The protocol stipulates that a time interval with the largest value is selected from multiple time intervals associated with the second type of DSR as the first interval, or any time interval with a value greater than multiple time intervals associated with the second type of DSR is selected as the first interval. In this case, the network device does not need to send a network indication.

[0171] S2102: UE determines the first interval.

[0172] In some embodiments, the first interval may be an interval for counting the data volume of the second type of data. If the first type of data and the second type of data exist in a PDU set at the same time, the data volume of the second type of data is counted in the BS value corresponding to the first interval.

[0173] In some embodiments, the first interval is determined according to the DSR configuration information. In this way, the network device can flexibly configure the first interval as needed.

[0174] In some embodiments, the first interval is determined according to a protocol agreement. In this way, the network device does not need to specifically configure the first interval through network messages such as DSR configuration information, which can save signaling overhead.

[0175] In some embodiments, the UE determines a first interval for reporting second type data in the second type DSR.

[0176] In some embodiments, before determining the first interval or when determining the first interval, the UE will also determine multiple time intervals associated with the second type of DSR.

[0177] In some embodiments, the UE determines multiple time intervals associated with the second type of DSR according to the DSR configuration information.

[0178] In some embodiments, the UE determines multiple time intervals associated with the second type of DSR based on the number of thresholds configured for the second type of DSR.

[0179] In some embodiments, the second type of DSR is configured with n thresholds, and then determining the second type of DSR is associated with n time intervals.

[0180] In some embodiments, the second type DSR is configured with n thresholds and the largest threshold among the n thresholds is smaller than the first threshold, then based on the n thresholds and the first threshold, it is determined that the second type DSR is associated with n+1 time intervals.

[0181] In some embodiments, the value range of the n time intervals is determined according to the number of thresholds n agreed upon in the protocol or indicated by the network and the first threshold.

[0182] In some embodiments, the value range of n+1 time intervals is determined according to the number of thresholds n agreed upon in the protocol or indicated by the network and the first threshold.

[0183] Assuming n=3, and the first threshold Ams, 0-Ams can be evenly or unequally divided into 3 time intervals or 4 time intervals.

[0184] S2103: UE sends DSR.

[0185] In some embodiments, upon detecting at least one LCG triggering event, the UE sends a DSR to the network device. Exemplarily, upon detecting that the remaining duration of at least one LCG is less than a first threshold, the UE sends a DSR to the network device. The triggering event may be any event that triggers the UE to send a DSR.

[0186] In some embodiments, the UE sends a first type of DSR to the network device.

[0187] In some embodiments, the UE sends a second type of DSR to the network device.

[0188] In some embodiments, the UE sends a first type DSR and a second type DSR to the network device.

[0189] In some embodiments, the UE sends the first type DSR or the second type DSR to the network device according to the network instruction.

[0190] In some embodiments, the UE sends a first type of DSR or a second type of DSR to the network device according to the type of DSR associated with the detected triggering event.

[0191] In some embodiments, the UE detects triggering events of the first type DSR and the second type DSR respectively, and sends the first type DSR or the second type DSR to the network device according to the local policy. For example, according to the second type DSR priority policy, the second type DSR is sent to the network device first, and according to the indication reporting policy of the second type DSR, if no special indication is detected that the second type DSR needs to be used, the first type DSR is sent to the network device first.

[0192] In some embodiments, the UE determines to report the first type DSR or the second type DSR according to network instructions.

[0193] In some embodiments, the association relationship between the first type DSR and the second type DSR may also be reflected in a message carrying the first type DSR and the second type DSR.

[0194] Exemplarily, the DSR is carried in the MAC CE.

[0195] In some embodiments, the first type of DSR and the second type of DSR are carried in different media access control MAC control elements CE. In some embodiments, the first type of DSR and the second type of DSR are carried in the same MAC CE. Different MAC CEs may have different identifiers or be sent using different communication resources. If the first type of DSR and the second type of DSR are reported to the network device using the same MAC CE, the UE may ignore the type of DSR currently being reported and use the MAC CE shared by the first type of DSR and the second type of DSR to send the DSR currently to be reported. If the first type of DSR and the second type of DSR are reported to the network device using different MAC CEs, the UE determines the MAC CE to be used based on the type of DSR to be reported.

[0196] In some embodiments, the first type DSR and the second type DSR for the same LCG may be carried in the same or different MAC CEs and sent to the network device.

[0197] In some embodiments, the first type DSR and the second type DSR of different LCGs may be carried and reported in the same MAC CE. In this case, the DSR carried by one MAC CE may include the first type DSR and the second type DSR from different LCGs.

[0198] In some embodiments, the first type DSR and the second type DSR of different LCGs may be carried and reported in different MAC CEs. In this case, the DSR carried by one MAC CE may include the first type DSR from different LCGs. Alternatively, the DSR carried by one MAC CE may include the second type DSR from different LCGs.

[0199] In some embodiments, when the UE sends the second type of DSR, it determines whether there is second type of data in the PDU set to send the delay status information. If there is second type of data, the amount of the second type of data is counted in the first interval. In some embodiments, a PDU set has a remaining duration of at least one PDU, and determines to send the second type of DSR of the PDU.

[0200] In some embodiments, the DSR may also include the first information.

[0201] In some embodiments, the first information may be any information used to determine the remaining duration corresponding to the BS value.

[0202] In some embodiments, the first information is used to indicate the minimum remaining duration, the average remaining duration or the maximum remaining duration of the data in each of the time intervals; or, the first information is an interval index of each of the time intervals.

[0203] In some embodiments, the DSR may not need to carry the first information. For example, if the DSR of the first type is currently being sent, then the DSR of the first type corresponds to a time interval, and the information related to the remaining duration may be directly sent, or the information related to the remaining time domain duration may be retained. In other embodiments, if the DSR of the second type is currently being sent, and the BS values ​​of multiple time intervals associated with the second type of DSR are sorted according to the value size of the time interval, then the first information may also be omitted at this time to save signaling overhead.

[0204] like Figure 3 As shown, the embodiment of the present disclosure provides a DSR transmission method, which is performed by a UE. The method may include:

[0205] S3101: Receive network instructions.

[0206] In some embodiments, the UE receives a network indication sent by a network device. For example, the network indication may be described in detail in Figure 2 S2101 of the corresponding embodiment.

[0207] S3102: Determine the first interval.

[0208] In some embodiments, the UE determines the first interval according to a protocol or a network instruction.

[0209] In some embodiments, the optional method of determining the first interval by the UE can be found in Figure 2 S2102 of the corresponding embodiment will not be repeated here.

[0210] S3103: Send DSR.

[0211] In some embodiments, the UE sends a DSR to the network device. For example, an optional implementation of the UE sending the DSR can be found in Figure 2 S2103 of the corresponding embodiment.

[0212] It is worth noting that any one of S3101 to S3103 can be implemented alone, and any two of S3101 to S3103 can be implemented in combination. For specific reasons, see Figure 2Corresponding implementation examples. For example, if the UE receives a network indication, but currently does not detect a triggering event for sending a DSR, then both S3102 and S3103 can be omitted. For another example, if the UE can determine the first interval by agreement, then there is no need to receive a network indication, and S3101 is an optional step. For another example, if the UE determines to send the first type of DSR, then there is no need to receive a network indication and / or determine the first interval at this time, which is equivalent to S3101 and S3102 being optional steps. Of course, a network indication can also be received, that is, a combined implementation example of S3102 and S3103. Of course, S3101, S3102 and S3103 can also be implemented in combination.

[0213] like Figure 4 As shown, the embodiment of the present disclosure provides a DSR transmission method, which is performed by a network device. The method may include:

[0214] S4101: Send network instructions.

[0215] In some embodiments, the network device sends a network indication to the UE. For example, the relevant description of the network indication can be found in Figure 2 The corresponding embodiments.

[0216] S4102: Receive DSR.

[0217] In some embodiments, the network device receives a DSR sent by the UE. For example, the description of the DSR can be found in Figure 2 The corresponding embodiments.

[0218] In some embodiments, the received DSR is a second-type DSR. In this case, the second-type DSR may carry a data volume of second-type data, and the data volume of the second-type data is carried in the first interval.

[0219] It is worth noting that: S4101 and S4102 can be implemented separately or in combination. For example, the network device sends a network indication, but may not be able to receive the DSR sent by the UE. In other embodiments, if the first interval is agreed upon by the protocol, S4101 can be omitted in this case. In some embodiments, the network device sends a network indication indicating the first interval, receives the DSR sent by the UE, and determines the first interval containing the amount of data of the second category of data based on the network indication.

[0220] A method for processing DSR is provided in an embodiment of the present disclosure, which may include: for one LCG, the DSR will carry at least one set of remaining duration information and a BS value.

[0221] In some embodiments, the remaining duration information and BS value of the same group point to the same time interval of the remaining duration. For example, if group A is associated with time interval 1, the remaining duration information of group A points to the minimum remaining duration, average remaining duration, maximum remaining duration, or lower boundary of time interval 1 of the PDU whose remaining duration is in time interval 1. The BS value of group A indicates the data volume of all PDUs whose remaining duration is in time interval 1.

[0222] For one LCG, the first type DSR may carry one reporting domain. For one LCG, the second type DSR may carry at least one reporting domain. Exemplarily, for one LCG, the second type DSR may carry multiple reporting domains. One reporting domain may carry a set of remaining duration information and BS value.

[0223] The UE determines the time interval of the remaining duration information according to the network configuration and / or protocol agreement, and then reports the BS value according to the time interval of the remaining duration information.

[0224] The second type of DSR can be used for reporting delay critical delay status information. Delay critical data can be divided into two categories. The two types of delay critical data can be: first type of delay critical data (i.e., the aforementioned first type of data) and second type of delay critical data (i.e., the aforementioned second type of data). Exemplarily, the type of delay critical data is determined based on the remaining duration.

[0225] Exemplarily, if the remaining time is not less than the threshold, the delay critical data is the first type of delay critical data. If the remaining time is less than the threshold, the delay critical data is the second type of delay critical data. In this way, the urgency of the first type of delay critical data is lower than the urgency of the second type of critical data.

[0226] In some embodiments, the first category of data volume will be counted and reported in a specific time interval of the remaining duration information.

[0227] The remaining duration of the first type of delay critical data is not less than the threshold, and it is not originally data that needs to report delay status information. However, since the first type of delay critical data and the second type of critical delay data belong to the same PDU set, if there is at least one PDU in the PDU set whose remaining duration is less than the threshold, the PDU set needs to report delay status information. At this time, the specific time interval for setting the BS value of the PDU with a remaining duration greater than the threshold in the PDU set is a question that needs further discussion.

[0228] Here are a few options:

[0229] Mode 1: The time interval corresponding to the first type of delay critical data may be any one of the multiple time intervals associated with the DSR. For example, for the first type of delay critical data, the time interval to which the remaining duration information belongs may be the time interval agreed by the UE according to the network configuration and / or protocol.

[0230] Exemplarily, the network device is configured with multiple thresholds, and the multiple thresholds are used to determine multiple time intervals below the threshold. For example, if the network device is configured with threshold 1 and threshold 2 and threshold 1 is less than threshold 2, two time intervals can be formed, and they are: 0-threshold 1 and threshold 1-threshold 2. In this case, the data volume of the first type of delay critical data will be counted in a specific time interval configured by the network device within the above two intervals, or a specific time interval agreed upon by the protocol.

[0231] For another example, if the network device is configured with threshold 1, threshold 2 and threshold 3, and threshold 1 is less than threshold 2, and threshold 2 is less than threshold 3, then there can be three time intervals, namely 0-threshold 1, threshold 1-threshold 2 and threshold 2-threshold 3.

[0232] In some embodiments, the specific time interval configured or agreed upon by the network device may be a time interval where an extreme value is located among multiple time intervals. The extreme value may be a time interval where a maximum value or a minimum value of the remaining duration corresponding to multiple time intervals is located. That is, the specific time interval is an interval with a larger value or an interval with a smaller value among multiple time intervals, wherein preferably, the specific time interval is an interval with a larger value among multiple time intervals. For example, when there are 3 time intervals, and they are 0 to threshold 1, threshold 1 to threshold 2, and threshold 2 to threshold 3, respectively, the specific time interval is preferably threshold 2 to threshold 3. In this way, the remaining time of the first type of data itself is not lower than the threshold, but because its data volume needs to be counted in the data volume reported by the DSR, it is more reasonable to count its data volume in the one with the closest value among the multiple time intervals associated when the DSR is reported.

[0233] In other embodiments, if the threshold agreed upon by the protocol or configured by the network includes threshold 1 and threshold 2. The time interval is two time intervals, 0 to threshold 1 and threshold 1 to threshold 2, wherein threshold 2 may be the reporting threshold of the DSR. At this time, the data volume of the first type of delay critical data will be reported by the larger value of the two time intervals, that is, it will be reported in the time interval where threshold 1 to threshold 2 are located.

[0234] For example, if the DSR threshold is 6ms, multiple time intervals are set according to the threshold 6ms. For example, if three time intervals are set, and the duration of each time interval is equal, 0-2ms can constitute interval A, 2ms-4ms can constitute interval B, and 4ms-6ms can constitute interval C.

[0235] In this case, the DSR will carry BS values ​​for up to 3 time intervals.

[0236] Time interval BS value explain Interval A (less than 2ms) X-bit The remaining time of X bits of data is less than 2ms The second interval B (less than 4ms) Y Bit The remaining duration of Y bits of data is less than 4ms The third interval C (less than 6ms) Zbit The remaining time of Z-bit data is less than 6ms

[0237] If the specific time interval is the third interval, the data volume of the first type of delay critical data with a remaining duration greater than 6ms will be counted in the third interval.

[0238] Assuming that the first type of delay critical data with a remaining duration greater than 6 ms has A bits, the BS value corresponding to the third interval is (Z+A) bits.

[0239] Method 2:

[0240] The time interval corresponding to the first type of delay critical data may be a time interval outside the multiple time intervals associated with the DSR. In mode 2, the BS value of the PDU with a remaining time greater than the threshold may be carried in a specific time interval outside the multiple time intervals associated with the DSR by protocol agreement or network device configuration. For example, the lower limit value of the specific time interval is greater than the threshold. For example, the lower limit value of the specific time interval is greater than the trigger threshold of the DSR.

[0241] The time interval of the specific remaining duration information can be reported by the UE in another separate interval other than the multiple time intervals associated with the DSR according to the network configuration and / or protocol agreement.

[0242] In some embodiments,

[0243] The network configures multiple thresholds. These multiple thresholds can be used by the UE to determine the time interval. For example, the network device is configured with threshold 1 and threshold 2. If threshold 1 is less than threshold 2, the time intervals are divided into: 0-threshold 1 and threshold 1-threshold 2. Assume that 0-threshold 1 is interval 1. Threshold 1-threshold 2 is interval 2, then the first type of delay critical data can be reported in interval 3. Interval 3 is different from both interval 1 and interval 2. Furthermore, the minimum value of interval 3 may be equal to the maximum value of interval 2, or any value of interval 3 is greater than the values ​​of interval 1 and interval 2.

[0244] The UE calculates the statistical quantity according to the remaining duration of the PDU in the time interval. The remaining duration indicated by the remaining duration information carried in the DSR report may be: the minimum / maximum / average value of the remaining duration of the PDU in the time interval.

[0245] In some embodiments, since the remaining duration of the PDU in interval 3 is greater than the threshold, the remaining duration of these PDUs may or may not be reported. Therefore, the remaining duration information of these PDUs may be omitted, and the BS values ​​of these PDUs may be sent through the reporting field corresponding to interval 3, thereby saving the bit overhead of DSR.

[0246] In some embodiments, the reporting field of DSR corresponding interval 3 may also carry the minimum remaining time or average remaining time of the corresponding PDU, so as to facilitate the network side to know the changes of PDUs with remaining time below the threshold in the PDU set in the future.
