[0094] 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 is also the aforementioned UE.

The access network device may include an evolved NodeB (eNB), a next generation evolved NodeB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved nodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, and at least one of an access node in a Wi-Fi system, but is not limited thereto.

[0098] In some embodiments, the technical approach of the present disclosure may be applicable to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure may become internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces may be implemented through software or programs.

[0099] In some embodiments, the access network device may be composed of a centralized unit (central unit, CU) and a distributed unit (distributed unit, DU), wherein the CU may also be referred to as a control unit (control unit). 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.

[0100] 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).

[0101] 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.

[0102] 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.

[0103] 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).

[0104] 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 (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 PDU 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 the PDU 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).

[0105] 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. 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.

[0106] 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.

[0107] 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.

[0108] The Remaining Time field may be used to indicate the amount of data of the PDU within the corresponding time interval, that is, the BS value.

[0109] 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.

[0110] The BT field and the remaining time and cache size fields of an LCG may be set in two octets that are continuously distributed.

[0111] Figure 2 FIG. 1 is an interactive schematic diagram of a DSR transmission method according to an exemplary embodiment. Figure 2 As shown, the embodiment of the present disclosure relates to a DSR transmission method, which is used in a communication system 100, and the method includes:

[0112] Figure 2 FIG. 1 is an interactive schematic diagram of a DSR transmission method according to an exemplary embodiment. Figure 2 As shown, the embodiment of the present disclosure relates to a DSR transmission method, which is used in a communication system 100, and the method includes:

[0113] S2101: The UE determines at least one time interval of DSR.

[0114] In some embodiments, the DSR may include a first type DSR and a second type DSR.

[0115] 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. The delay status information may be information reflecting the remaining delay of data to be transmitted. Exemplarily, the delay status information may include at least a buffer size (BS) value associated with a time interval.

[0116] The following is an example of the association relationship between the first type DSR and the second type DSR.

[0117] Association method 1: The second type of DSR can be regarded as a special form of the first type of DSR.

[0118] In this case, the reporting of the delay status information for the LCG may include at least one of the following characteristics:

[0119] The triggering events for the second type of DSR are the same as those for the first type of DSR;

[0120] For an LCG, the prerequisite for configuring the second type of DSR is to configure the first type of DSR; that is, for an LCG, the first type of DSR can be configured separately, or the first type of DSR and the second type of DSR can be configured at the same time. When an LCG is configured with both the first type of DSR and the second type of DSR, whether to use the first type of 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 the first type of DSR or the second type of DSR according to the number of time intervals to which the remaining duration of the PDU that the LCG needs to meet the triggering event belongs. For example, if the remaining duration of the PDU that an LCG meets the triggering event is distributed in a time interval, the first type of DSR can be used to report the delay status information of the LCG in priority, so as to minimize unnecessary network signaling overhead. If the remaining duration of the PDU that an LCG meets the triggering event 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.

[0121] 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 first type DSR and / or the second type DSR.

[0122] 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 first type of 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 first type of DSR.

[0123] In some embodiments, corresponding to association relationship 1, the triggering events of the first type DSR and the second type DSR may be: there is at least one logical channel group LCG whose remaining duration is less than the first threshold.

[0124] Relationship 2: The second type of DSR and the first type of DSR are two different types of DSRs that are parallel.

[0125] In this case, the reporting of the delay status information for the LCG may include at least one of the following characteristics:

[0126] The triggering events of the second type DSR and the first type DSR are set separately. In this case, the triggering events of the second type DSR and the first type DSR may be the same or different. Whether they are the same depends on the specific settings of the triggering events of the first type DSR and the second type DSR.

[0127] For an LCG, the first type of DSR can be configured separately, the second type of DSR can be configured separately, or the first type of 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).

[0128] In some embodiments, the capability information is used by the network device to determine whether the UE supports the second type of DSR.

[0129] In some embodiments, it is assumed that all UEs support the first type of 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 the DSR report in different capability information, thereby saving at least part of the UE's bit overhead.

[0130] 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 first type of DSR. Of course, in some embodiments, even corresponding to association relationship 2, the prerequisite for the UE to support the second type of DSR is that the UE supports the first type of DSR.

[0131] If the prerequisite for the UE to support the second type of DSR is the first type of DSR, then the UE indicates through capability information that it supports the second type of DSR, which means that the UE must also support the first type of DSR.

[0132] If the UE supports the second type of DSR and whether it supports the first type of DSR, the UE indicates support for the second type of DSR through capability information, and whether the UE supports the first type of DSR needs to be additionally determined.

[0133] In some embodiments, the UE can report capability information so that the network device can know the UE's capability in DSR reporting, so that the DSR can be configured for the LCG configured for the UE in a targeted manner according to the UE's capability.

[0134] In some embodiments, the capability information of the UE may be executed separately. For example, the base station may configure the DSR for the LCG configured for the UE according to the capability information of the UE after receiving the capability information of the UE. For another example, if the base station believes that there are many idle resources at present and the probability that the LCG configured by the UE has not yet allocated resources for transmission is small, the configuration of the DSR may be omitted, and the base station may only store the capability information of the UE.

[0135] In some embodiments, S2101 may also be an optional step. For example, the network device may determine the type of DSR supported by the UE based on the type of UE. In this case, the base station and other network devices do not need the UE to report capability information, but can also know the type of DSR supported by the UE. At this time, the UE can omit the sending of capability information. For another example, the protocol stipulates the type of DSR that some or all UEs need to support, and the base station and other network devices can know the type of DSR supported by the UE according to the protocol. In this case, the UE can also omit the reporting of capability information.

[0136] In some embodiments, the UE determines at least one time interval of the DSR according to the DSR configuration information.

[0137] In some embodiments, the UE determines at least one time interval of the second type of DSR according to the DSR configuration information.

[0138] In some embodiments, the DSR configuration information may include but is not limited to at least one of the following: the type of DSR; resource information of the DSR, which may indicate one or more of the time domain resources and frequency domain resources for the UE to send the DSR; configuration information of the time interval associated with the DSR, for example, the information of the time interval may include one or more thresholds; configuration information of the trigger event associated with the DSR.

[0139] In some embodiments, the first type DSR and the second type DSR may share a set of DSR configuration information, and the DSR configuration information may include a first part and a second part. The first part may be a common part, and the common part includes the same parameters of the first type DSR and the second type DSR. The second part may include difference parameters of the first type DSR and the second type DSR. By sharing the DSR configuration information, the overhead of configuration signaling can be saved. Exemplarily, the situation where the first type DSR and the second type DSR share a set of DSR configuration information is particularly applicable to the aforementioned association relationship.

[0140] In some embodiments, the first type of DSR and the second type of DSR do not share DSR configuration information, which is equivalent to the network device configuring parameters of the first type of DSR and the second type of DSR respectively.

[0141] If the network device may be configured with different first thresholds for the first type DSR and the second type DSR respectively, the corresponding type of DSR may be selected for sending according to the current remaining duration being less than the first threshold.

[0142] In some other embodiments, the UE may determine to use the reported DSR type according to the configuration of different types of DSR configuration information. In this case, the network device may also omit the sending of the network indication.

[0143] In other embodiments, the UE determines the number of time intervals associated with the second type of DSR according to a protocol agreement.

[0144] In some embodiments, the UE determines a time interval associated with the first type of DSR.

[0145] In some other embodiments, the UE determines at least two time intervals associated with the second type of DSR.

[0146] In a specific implementation, there are multiple ways for the UE to determine at least one time interval associated with the DSR, and the specific implementation is not limited to any of the following:

[0147] Method 1: Determine at least one time interval of DSR according to the number of thresholds.

[0148] Exemplarily, determining at least one time interval of the DSR according to the number of thresholds may include at least one of the following:

[0149] According to the number n of thresholds and the first threshold corresponding to the trigger event, n+1 time intervals associated with the second type of DSR are determined, and the mth time interval can be any two adjacent values ​​of 0, n thresholds, and the first threshold in order of size; m can be a positive integer less than or equal to n+1;

[0150] According to the number of thresholds, n time intervals associated with the second type of DSR are determined, and the mth time interval can be 0 and any two adjacent values ​​of the n thresholds in order of size; m can be a positive integer less than or equal to n.

[0151] Method 2: Determine at least one time interval of DSR association based on a threshold.

[0152] In some embodiments, the threshold here can be configured by the network device or agreed upon by the protocol. Exemplarily, the threshold is configured by DSR configuration information.

[0153] In some embodiments, if the network device configures X thresholds for the UE, two thresholds with adjacent values ​​among the X thresholds may constitute a time interval. Thus, when the largest threshold among the X thresholds is less than the first threshold, X+1 thresholds may be constituted.

[0154] Mode 3: Determine at least one time interval of the DSR according to a first threshold for sending the DSR report.

[0155] In some embodiments, at least one time interval of the DSR is determined based on the duration of a single time interval and a first threshold. Exemplarily, if the network device configuration or protocol stipulates the duration of each time interval, then when the first threshold is determined, at least one time interval associated with the DSR can be determined based on the first threshold and the predetermined duration. For example, assuming that the duration of a single time interval is agreed to be 2ms, if the first threshold is equal to 8ms, then there are 4 time intervals, which are 0-2ms, 2-4ms, 4-6ms, and 6-8ms respectively.

[0156] In other embodiments, at least one time interval of the DSR is determined based on the first threshold and the number of intervals. Exemplarily, if the network device configures X thresholds for the UE and the largest threshold among the X thresholds is equal to the first threshold, then X thresholds can be constituted. Also exemplarily, the network device configuration or protocol can stipulate the number of protocol time intervals, and the UE determines each time interval based on the number of time intervals and the first threshold. For example, assuming that the network device configuration or protocol stipulates that the number of time is Y, 0 to the first threshold can be divided equally or unequally into Y time intervals, and these Y time intervals are at least one time interval associated with the DSR.

[0157] In some embodiments, the number of intervals is agreed upon by a protocol, or the number of intervals is configured by the network device. In summary, in some cases, the multiple time intervals depend on the number of thresholds; or the multiple time intervals depend on the trigger threshold and the number of intervals.

[0158] S2102: The UE sends a DSR to the network device.

[0159] 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.

[0160] 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.

[0161] In some embodiments, the UE sends a first type of DSR to the network device.

[0162] In some embodiments, the UE sends a second type of DSR to the network device.

[0163] In some embodiments, the UE sends a first type DSR and a second type DSR to the network device.

[0164] In some embodiments, the UE sends the first type DSR or the second type DSR to the network device according to the network instruction.

[0165] In some embodiments, the network device 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.

[0166] In some embodiments, the network device detects the 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.

[0167] In some embodiments, the association relationship between the first type DSR and the second type DSR may also be indicated in a message carrying the first type DSR and the second type DSR. Exemplarily, the DSR is carried in a MAC CE.

[0168] 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.

[0169] 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.

[0170] 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.

[0171] 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.

[0172] In some embodiments, the first type DSR may carry one reporting domain, for example, the second type DSR may carry one reporting domain of one LCG. In other embodiments, the second type DSR may carry multiple reporting domains, for example, the second type DSR may carry one or more reporting domains of one LCG. The reporting domain here may be used to carry delay status information.

[0173] In some embodiments, one of the multiple reporting domains included in the second type DSR carries the BS value of the PDU to be transmitted whose remaining duration is within the time interval associated with the reporting domain. For example, assuming there are 3 time intervals, if reporting domain A is associated with time interval 2, the BS value carried by reporting domain A is the BS value of the data to be transmitted whose remaining duration is within time interval 2.

[0174] In other embodiments, one of the multiple reporting domains included in the second type DSR carries a BS value of the data to be transmitted whose remaining duration is below the upper limit of the time interval associated with the reporting domain. For example, assuming there are three time intervals, if reporting domain A is associated with time interval 2, the BS value carried by reporting domain A is the BS value of the data to be transmitted whose remaining duration is within time interval 2 and whose remaining duration is within time interval 1. The value of time interval 1 is smaller than the value of time interval 2.

[0175] In some embodiments, the reporting domains for the second type of DSR can be divided into two categories, namely, the first type of reporting domain and the second type of reporting domain. Exemplarily, the second type of DSR can include the first type of reporting domain and / or the second type of reporting domain.

[0176] In some embodiments, the first type of reporting domain includes first information and a BS value; the first information is used to determine the remaining duration corresponding to the BS value.

[0177] In some embodiments, the first information is information that explicitly indicates the remaining duration, and usually occupies one or more bits.

[0178] In some embodiments, the first information is duration information, which is used to indicate that the remaining duration belongs to the minimum remaining duration, the maximum remaining duration, or the average remaining duration of the PDU in the first interval.

[0179] In some other embodiments, the first information may be an interval index, where the interval index is used to indicate the time interval in which the remaining duration of the BS value is located.

[0180] In some embodiments, the number of first-category reporting domains of an LCG included in the DSR may be less than or equal to the number of time intervals associated with the DSR, and the number of first-category reporting domains of an LCG ultimately carried by the DSR depends on the number of time intervals to which the remaining duration of the remaining PDUs to be transmitted by the LCG belongs. Exemplarily, the number of the first-category reporting domains included in the DSR is equal to the number of time intervals in which the PDUs whose remaining duration is less than the first threshold are located.

[0181] In some embodiments, the first type reporting field also includes a first indication field.

[0182] In some embodiments, the first indication field is used by the network device to determine the number of first-category reporting fields included in an LCG or the number of first-category reporting fields included in a DSR.

[0183] In some embodiments, the first indication field is used to indicate whether there is an (n+1)th first-category reporting field after the nth first-category reporting field.

[0184] For example, the first n first-class reporting domains are associated with n first indication domains, and the nth first indication domain is used to indicate whether there is an n+1th first-class reporting domain after the nth first reporting domain. The first n first-class reporting domains are associated with n first indication domains and may belong to the same octet or two adjacent octets. Exemplarily, one first-class reporting domain may correspond to one first indication domain. Exemplarily, the first indication domain may include a reserved bit for DSR.

[0185] In some embodiments, the first indication field may include one or more newly added octets for indicating the first type of reporting fields included in a DSR or an LCG. The newly added octets may be specifically used to determine the number of first type reporting fields included in a DSR or an LCG.

[0186] In some embodiments, the second type of reporting field includes the BS value but does not include the first information. That is, the second type of reporting field does not include information that explicitly indicates the remaining duration. The bit overhead of the first information is saved in the second type of reporting field.

[0187] In some embodiments, if the DSR includes a second-class reporting domain, multiple second-class reporting domains are sorted from large to small according to the value of the time interval, or from small to large, or sorted in a specified order according to the importance (the value of the time interval is irrelevant at this time).

[0188] In some embodiments, the number of second-type reporting fields of an LCG included in a DSR is equal to the number of time intervals associated with the DSR.

[0189] In some embodiments, if the remaining duration of no data falls into a certain time interval, the BS value corresponding to the time interval is 0, and the value 0 is carried in the corresponding second-type reporting field of the DSR.

[0190] In some embodiments, the number of bits included in a second-type reporting field may be smaller than the number of bits included in a first-type reporting field. Exemplarily, a second-type reporting field includes one octet, and a first-type reporting field may include two octets.

[0191] Of course, in some cases, the DSR containing the second type of reporting field can omit the first indication field. For example, the number of second type reporting fields contained in a DSR is related to the number of LCG groups for which the DSR currently needs to report delay status information. In this way, when the network device receives a DSR carrying the second type of reporting field, it can calculate how many second type reporting fields the DSR carries based on the time interval associated with the DSR and the number of LCG groups for which delay status information is to be reported indicated by the LCG field, so as to facilitate the network device to quickly decode the DSR.

[0192] In some embodiments, a DSR including a second-type reporting field may also carry a first indication field, and the first indication field may further explicitly indicate the number of second-type reporting fields included in a DSR or an LCG.

[0193] In some embodiments, the DSR may further include a second indication field. Exemplarily, the first type reporting field and / or the second type reporting field may both include the second indication field.

[0194] In some embodiments, the second indication field is used to indicate a table for reference in calculating the BS value. Different tables are provided with different ways of calculating the BS value, so that the same PDU to be transmitted may use different tables, and the BS values ​​determined may be different. For example, different tables are used for different degrees of quantization of the BS value, etc.

[0195] In some embodiments, multiple reporting domains in an LCG may refer to the same table or different tables, preferably the same table. The reporting domains of different LCGs in a DSR may refer to the same table or different tables, preferably the same table. In the case where multiple reporting domains of an LCG refer to the same table, an LCG may correspond to a second indication domain, and at least the tables referenced by multiple reporting domains of the LCG are the same through a second indication domain, rather than a reporting domain being associated with a second indication domain, thereby saving the bit overhead of the reporting domain. In some embodiments, the second indication domain may also be divided into two categories, one is the second indication domain for the entire DSR, and the other is the second indication domain for the LCG. For example, in the second indication domain facing the entire DSR, when all LCG groups reported by the DSR refer to the same table, the second indication domain associated with the LCG can be omitted, thereby saving bit overhead. In the case where different LCGs refer to different tables, the second indication domains of each LCG are retained to indicate the tables referenced by each LCG respectively.

[0196] In the disclosed embodiment, when the UE sends a DSR, the network device receives the corresponding DSR and decodes it according to the DSR format, thereby scheduling wireless resources for the UE according to the delay status information of each LCG reported by the DSR.

[0197] 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:

[0198] S3101: Determine at least one time interval associated with the DSR.

[0199] In some embodiments, an optional method for the UE to determine at least one time interval associated with the DSR may be found in Figure 2 The relevant description of step S2101 of the corresponding embodiment.

[0200] S3102: Send DSR.

[0201] In some embodiments, the UE sends the DSR to the network device.

[0202] In some embodiments, an optional method for the UE to determine at least one time interval associated with the DSR may be found in Figure 2 The relevant description of step S2102 of the corresponding embodiment.

[0203] It is worth noting that any one of S3101 to S3102 can be implemented separately, and S3101 and S3102 can also be implemented in combination. For example, the UE determines at least one time interval associated with the DSR, but does not detect a triggering event for the DSR, so it is not necessary to send the DSR. For another example, if the UE already knows at least one time interval associated with the DSR in advance, it can also skip this step and proceed to the execution of S3102.

[0204] 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:

[0205] S4101: Receive DSR.

[0206] In some embodiments, the network device receives a DSR sent by the UE.

[0207] For example, the relevant description of the DSR can be found in Figure 2 The corresponding embodiments.

[0208] In some embodiments, after receiving the DSR, the network device parses the DSR according to the format of the DSR. After acquiring the delay status information of each LCG reported by the UE, the network device performs corresponding radio resource scheduling.

[0209] The second type of DSR is introduced in the embodiment of the present disclosure. The second type of DSR may carry one or more groups of remaining duration information and BS values. Exemplarily, the second type of DSR may carry one or more reporting fields, and one reporting field may carry a group of remaining duration information and BS values.

[0210] Exemplarily, the remaining duration information and BS value of the same group point to the same time interval of 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.

[0211] In some embodiments, the second type DSR for an LCG may carry one or more reporting fields, which may be Remaining Time and Buffer Size fields.

[0212] In some embodiments, in order to distinguish between the first type DSR and the second type DSR, the LCID of the second type DSR may be different from that of the first type DSR. For example, a reserved LCID in the first type DSR may be used to indicate the second type DSR.

[0213] The relevant attributes or characteristics of the second type of DSR are determined from multiple aspects as follows.

[0214] The first aspect is the determination of the time period.

[0215] The UE determines the time interval according to network configuration and / or protocol agreement.

[0216] Embodiment 1: Determine the time interval according to the threshold. For example, the number of time intervals and / or the upper limit and lower limit of the time interval are determined according to the number of thresholds. In this case, the network device is configured with multiple thresholds, and the UE determines the time interval according to the multiple thresholds configured by the network device. The UE can also determine the time interval according to the multiple thresholds agreed upon in the protocol.

[0217] In some embodiments, the number of time intervals associated with the second type of DSR is equal to the number of thresholds, and the value range of the time interval can be determined based on two adjacent thresholds sorted by size.

[0218] For example, according to network device configuration or protocol agreement, the thresholds for the second type of DSR include: threshold 1 and threshold 2. At this time, according to the number of time intervals associated with the second type of DSR, the two time intervals are 0 to threshold 1 and threshold 1 to threshold 2.

[0219] Embodiment 2: The network device configures the number of intervals or the number of intervals agreed upon by the protocol, and determines the value range of each time interval according to the number of intervals and the trigger threshold for the UE to report the DSR. For example, assuming that the number of intervals is 2 and the trigger threshold is 10ms, the value range of interval 1 can be determined to be 0-5ms according to the equal division strategy, and the value range of interval 2 can be determined to be 5-10ms. For another example, assuming that the number of intervals is 3 and the trigger threshold is 6ms, the UE can determine 3 intervals according to the equal division strategy, and interval 1 is 0-2ms, interval 2 is 2ms-4ms, and interval 3 is 4ms-6ms.

[0220] In some embodiments, the strategy of determining the value range of each time interval according to the number of intervals is not limited to the equal division strategy. In some embodiments, it can also be determined according to the division ratio. For example, multiple ratios can be configured by the network device or agreed upon by the protocol for different numbers of intervals, and the value range of each time interval can be determined according to the ratio. For example, assuming that the trigger threshold is 8ms, the number of intervals is 3 and the ratio is: 1:2:1, then the value ranges of the three time intervals are: 0~2ms, 2ms~6ms, 6ms~8ms respectively.

[0221] Embodiment 3: The number of intervals configured by the network device or the number of intervals agreed upon by the protocol, the threshold configured by the network device or agreed upon by the protocol In this case, the UE can determine the number of time intervals and the value range of each time interval according to the number of intervals, the threshold and the triggering threshold.

[0222] For example, the protocol stipulates the number of intervals, such as 3 and two thresholds. In this case, the three intervals are 0 to threshold 1, threshold 1 to threshold 2, and threshold 2 to trigger threshold. The above gives three ways to determine the time interval.

[0223] In some embodiments, for one LCG, the second type DSR may also be associated with a time interval. Exemplarily, for one LCG, a time interval less than the trigger threshold associated with the second type DSR is determined according to the trigger threshold, and the data volume of the PDU with a remaining duration greater than the trigger threshold may be carried in the time interval not associated with the second type DSR and exceeding the trigger threshold for reporting.

[0224] In some embodiments, if only one time interval is set for an LCG, the first type of DSR may also be used to report delay status information.

[0225] Secondly, the statistical method of BS value can be as follows:

[0226] Method 1: The UE counts the BS values ​​to be reported in different time intervals.

[0227] In this way, after triggering the DSR report, the UE carries at least one set of delay status information for one LCG. A set of delay status information is a BS value, or corresponding remaining duration information and BS settings. For example, the DSR may include one or more reporting domains. A reporting domain can be used to report a set of delay status information. Different reporting domains correspond to different time interval value ranges. Before reporting the DSR, the UE counts statistical quantities in time intervals according to the remaining duration of the PDU, that is, counts the BS values ​​in time intervals.

[0228] Exemplarily, if the triggering threshold of DSR is 6 ms, the DSR reports the BS value in each time interval below 6 ms, which may be shown in Table 1.

[0229]

[0230]

[0231] Table 1

[0232] Mode 2: The UE counts the data volume corresponding to each time interval according to the inclusion relationship between the time intervals.

[0233] Value range BS value explain Interval A (less than 2ms) X-bit The remaining time of X bits of data is less than 2ms Interval B (less than 4ms) X+Y bits The remaining duration of Y bits of data is less than 4ms Interval C (less than 6ms) X+Y+Z bits The remaining time of Z-bit data is less than 6ms

[0235] In Table 2, the X bit data volume is a subset of the Y bit data volume, and Y is a subset of the Z bit data volume. At this time, the gNB needs to perform a calculation to obtain the data volume of each interval. If this method is adopted, after receiving the DSR, the network device determines the specific data volume in each time interval based on the inclusion relationship between each BS value and the time interval.

[0236] After the BS value is determined as shown in Table 1 or Table 2, there are three ways to carry information in the reporting field in the DSR:

[0237] The first type: UE can display and report each group delay status information. For example, DSR can carry information through three reporting fields: {2ms, Xbit}; {4ms, Ybit}, {6ms, Zbit}; or, {2ms, Xbit}; {4ms, X+Ybit}, {6ms, X+Y+Zbit}.

[0238] The second method: The UE can indicate the time interval through the interval index. For example, in the DSR, three reporting fields can be used to carry information respectively: {0, Xbit}; {1, Ybit}, {2, Zbit}; or, {0, Xbit}; {1, X+Ybit}, {2, X+Y+Zbit}. Indicating the time interval through the interval index can reduce the bit overhead compared to directly using the remaining duration information.

[0239] The third type: the UE does not report the remaining duration information or the interval index. For example, the BS value of each time interval can be reported separately through three orderly arranged reporting fields in DSR. For example, three reporting fields can be used in DSR to carry information respectively: {X bit}, {Ybit}, {Zbit}, or, {Xbit}; {X+Ybit}, {X+Y+Zbit}. The sorting method of each time interval can be agreed upon by the UE and the network device. For example, sort from large to small according to the duration value corresponding to the time interval, or sort from small to large, or sort by a specified importance. For example, a sorting based on importance can be: the time interval with the smallest value, the time interval with the largest value, and the time interval with the middle value. This sorting method can be configured by the network device, UE suggestion or protocol agreement, etc. Using this method, the signaling overhead of DSR can be further saved.

[0240] As an embodiment, the UE collects statistical data according to the remaining duration of the PDU in segment intervals: however, the value of the remaining duration information is still the minimum, maximum or average value of the remaining duration of the PDU within the segment interval.

[0241] Exemplarily, taking the remaining duration information in Table 1 as an example, assuming that Xbit is X bit of data, the corresponding remaining time is in the range of 0-2ms, but the minimum remaining duration is 1.5ms, the Y bit of data, the corresponding remaining time is in the range of 2-4ms, but the minimum remaining duration is 2.5ms, and the Z bit of data, the corresponding remaining time is in the range of 4-6ms, but the minimum remaining duration is 4.5ms.

[0242] Examples of the contents carried by these three reporting fields may be shown in Table 3 or Table 4:

[0243] Value range BS value Remaining time Interval A (less than 2ms) X-bit 1.5ms Interval B (less than 4ms) X-bit 2.5ms Interval C (less than 6ms) X-bit 4.ms

[0244] Table 3

[0245] Value range BS value Remaining time Interval A (less than 2ms) X-bit 1.5ms Interval B (less than 4ms) X+Y bits 2.5ms Interval C (less than 6ms) X+Y+Z bits 4.ms

[0246] Table 4

[0247] If no data meeting the condition is detected in a certain time interval, there is no need to have a reporting domain for the interval or the reporting BS value is set to 0.

[0248] In some embodiments, there are multiple reporting domains in the DSR, and the value of BT can be multiplexed, or each reporting domain can use a different BT.

[0249] like Figure 1B As shown, if LCGi=1, it indicates that the current DSR contains the delay status information of the LCGi. The DSR can carry one or more reporting fields. By introducing the first indication field, it can indicate whether there are subsequent reporting fields after the current reporting field, which is convenient for the network device to quickly resolve.
