The access network device may include, but is not limited to, at least one of the following in a 5G communication system: evolved Node B (eNB), next generation eNB (ng-eNB), next generation Node B (gNB), node B (NB), home node B (HNB), home evolved node B (HeNB), radio backhaul device, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in a 6G communication system, open RAN, cloud RAN, base station in other communication systems, and access node in a Wi-Fi system.

[0099] In some embodiments, the technical methods of this disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0100] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0101] In some embodiments, the core network equipment can be a single device, including a first network element, or it can be multiple devices or a group of devices, each including a first network element. Network elements can be virtual or physical. The core network includes, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0102] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical methods of this disclosure and does not constitute a limitation on the technical methods provided in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical methods provided in this disclosure are also applicable to similar technical problems.

[0103] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1A, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1A are illustrative. The communication system may include all or some of the main bodies in FIG1A, or it may include other main bodies outside of FIG1A. The number and form of each main body are arbitrary. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0104] The embodiments disclosed herein can 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), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing configuration methods of other resources, and next-generation systems extended from them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE and NR).

[0105] The UE can request the network device to schedule the transmission of urgently needed or soon-to-time-out service data by sending a BSR to the network device. In some cases, a BSR can only be sent when high-priority logical channel data arrives, which cannot meet the needs of emergency scheduling. Therefore, optimization for emergency scheduling in XR needs to be considered. The UE can report a Delay Status Report (DSR) to the network device, which carries delay information. For example, if an uplink data has not been scheduled for a long time, causing the remaining time of its PDU to be less than a certain threshold, the UE will report the information of the uplink data and / or delay information through the DSR. The remaining time of the PDU is the time difference between the current time and the time when the packet is dropped. Typically, this remaining time is determined according to the drop timer of the Packet Data Convergence Protocol (PDCP).

[0106] The Delay Status Report (DSR) is used by the UE to send delay status information for the Logical Channel Group (LCG) to the network equipment. The delay status information may include: the remaining time information for the LCG and the total amount of delay-critical uplink data to be transmitted by the LCG. The remaining time information indicates the minimum remaining time in the Service Data Unit (SDU) that the PDCP has not yet transmitted.

[0107] Figure 1B shows a schematic diagram of a DSR. The DSR shown in Figure 1B includes the LCG field, BT field, Remaining Time field, and Buffer Size (BS) field.

[0108] The LCG field is used to indicate the LCG reported by the DSR. For example, if the indicator bit in the LCG field corresponding to a certain channel is 1, it indicates that the DSR contains delay status information for that LCG. If the indicator bit in the LCG field corresponding to a certain channel is 0, it indicates that the DSR does not contain delay status information for that LCG. In some embodiments, the delay status information may include the remaining duration information of the corresponding LCG and / or the BS value.

[0109] The Remaining Time carries information about the remaining duration, which is used to indicate the remaining time. In the disclosed embodiments, the remaining duration may also be referred to as the Remaining Time. This remaining time may be the shortest remaining duration of the PDCP discard timer.

[0110] The Remaining Time field can be used to indicate the amount of data in a PDU within the corresponding time interval, i.e., the BS value.

[0111] The BT field indicates the table referenced for calculating the BS value. If the BT field is 1, it means that the calculated BS value is from cache table 1; if the BT field is 0, it indicates the calculated BS value from cache table 2.

[0112] An LCG's BT field, as well as the remaining time and cache size fields, can be set within two consecutively distributed octets.

[0113] Figure 2 is an interactive schematic diagram illustrating a DSR transmission method according to an exemplary embodiment. As shown in Figure 2, this disclosure relates to a DSR transmission method for a communication system 100, the method comprising:

[0114] Figure 2 is an interactive schematic diagram illustrating a DSR transmission method according to an exemplary embodiment. As shown in Figure 2, this disclosure relates to a DSR transmission method for a communication system 100, the method comprising:

[0115] S2101: The UE determines at least one time interval of the DSR.

[0116] In some embodiments, DSR may include a first type of DSR and a second type of DSR.

[0117] In some embodiments, the first type of DSR includes a set of delay status information. For example, for an LCG, the first type of DSR includes a set of delay status information. This delay status information may be information reflecting the remaining delay of the data to be transmitted. For example, the delay status information may include at least a buffer size (BS) value associated with a time interval.

[0118] The following example illustrates the relationship between the first type of DSR and the second type of DSR.

[0119] Association Method 1: The second type of DSR can be regarded as a special form of the first type of DSR.

[0120] In this case, the reporting of delay status information for the LCG may include at least one of the following characteristics:

[0121] The triggering events for the second type of DSR are the same as those for the first type of DSR;

[0122] For an LCG, configuring a Type II DSR requires configuring a Type I DSR; that is, an LCG can be configured with a Type I DSR alone, or with both Type I and Type II DSRs simultaneously. When an LCG is configured with both Type I and Type II DSRs, the choice between Type I and Type II DSRs can be determined by the network, or by protocol agreement or negotiation with network equipment. In some embodiments, the UE can also determine whether to use Type I or Type II DSR based on the number of time intervals to which the remaining duration of the PDUs that trigger the event for the LCG belongs. For example, if the remaining duration of the PDUs that trigger the event for an LCG is distributed within one time interval, Type I DSR can be used first to report the LCG's delay status information to minimize unnecessary network signaling overhead. If the remaining duration of the PDUs that trigger the event for an LCG is distributed across multiple time intervals, Type II DSR can be used first to report the LCG's delay status information, thereby achieving refined reporting.

[0123] In some embodiments, the triggering 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 the maximum remaining duration value of the time interval associated with the first type of DSR and / or the second type of DSR.

[0124] In some embodiments, corresponding to association 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 is irrelevant to whether the UE supports the first type of DSR.

[0125] In some embodiments, corresponding to association 1, the triggering event for both the first type of DSR and the second type of DSR can be: the remaining duration of at least one logical channel group (LCG) is less than the first threshold.

[0126] Relationship 2: Type II DSR and Type I DSR are two parallel types of DSR.

[0127] In this case, the reporting of delay status information for the LCG may include at least one of the following characteristics:

[0128] The trigger events for the second type of DSR and the first type of DSR are set separately. In this case, the trigger events for the second type of DSR and the first type of DSR can be the same or different. Whether they are the same or not depends on the specific settings of the trigger events for the first type of DSR and the second type of DSR.

[0129] For an LCG, a Type I DSR can be configured individually, a Type II DSR can be configured individually, or both Type I and Type II DSRs can be configured simultaneously. The specific DSR configured for an LCG may depend on the network device configuration and / or the service attributes associated with the LCG, the urgency of the service data, and / or the Quality of Service (QoS).

[0130] In some embodiments, the capability information is used by the network device to determine whether the UE supports the second type of DSR.

[0131] In some embodiments, UEs support Type 1 DSR by default. In this case, when a UE supports Type 2 DSR, it can specifically indicate this to the network device through capability information. UEs that do not support Type 2 DSR can carry information related to DSR reporting in different capability information, thereby saving at least some of the bit overhead for the UE.

[0132] In some embodiments, corresponding to association 2, whether the UE supports the second type of DSR is irrelevant to whether the UE supports the first type of DSR. However, in some embodiments, even corresponding to association 2, the prerequisite for the UE to support the second type of DSR is that the UE supports the first type of DSR.

[0133] If the prerequisite for a UE to support Type 2 DSR is Type 1 DSR, then if the UE indicates support for Type 2 DSR through capability information, it means that the UE's support for Type 2 DSR necessarily means that it also supports Type 1 DSR.

[0134] If the UE supports Type 2 DSR and does not support Type 1 DSR, the UE indicates support for Type 2 DSR through capability information. Whether the UE supports Type 1 DSR needs to be determined separately.

[0135] In some embodiments, by reporting capability information, the UE can make it easy for network devices to know the UE's capabilities in DSR reporting, so that DSR can be configured for the LCG configured for the UE in a targeted manner according to the UE's capabilities.

[0136] In some embodiments, UE capability information can be executed independently. For example, upon receiving the UE's capability information, the base station can configure DSR for the LCG configured by the UE based on the UE's capability information. As another example, if the base station believes that there are currently many idle resources and the probability that the LCG configured by the UE will not be allocated resources for transmission for a long time is low, then the DSR configuration can be omitted; in this case, the base station may only store the UE's capability information.

[0137] In some embodiments, S2101 can also be an optional step. For example, the network device can determine the types of DSRs supported by the UE based on the UE type. In this case, the network device, such as the base station, can know the types of DSRs supported by the UE without the UE reporting capability information, and the UE can omit the transmission of capability information. Another example is that the protocol specifies some or all of the DSR types that the UE needs to support, and the network device, such as the base station, can know the types of DSRs supported by the UE according to the protocol. In this case, the UE can also omit the reporting of capability information.

[0138] In some embodiments, the UE determines at least one time interval of the DSR based on the DSR configuration information.

[0139] In some embodiments, the UE determines at least one time interval of the second type of DSR based on the DSR configuration information.

[0140] In some embodiments, 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 instruct the UE to transmit one or more of the time domain resources and frequency domain resources of 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; and configuration information of the triggering event associated with the DSR.

[0141] In some embodiments, the first type of DSR and the second type of DSR can share a set of DSR configuration information, which may include a first part and a second part. The first part may be a common part, which includes the same parameters for the first type of DSR and the second type of DSR. The second part may include the different parameters for the first type of DSR and the second type of DSR. By sharing the DSR configuration information, the overhead of configuration signaling can be saved. For example, the situation where the first type of DSR and the second type of DSR share a set of DSR configuration information is particularly applicable to the aforementioned association relationship.

[0142] 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 the parameters of the first type of DSR and the second type of DSR respectively.

[0143] If the network devices may be configured with different first thresholds for Type I DSR and Type II DSR, then the corresponding type of DSR can be selected for transmission based on the first threshold that the current remaining time is less than.

[0144] In other embodiments, the UE can determine the type of DSR to use based on the configuration of different types of DSR configuration information. In this case, the network device can also omit the issuance of network instructions.

[0145] In other embodiments, the UE determines the number of time intervals associated with the second type of DSR according to the protocol agreement.

[0146] In some embodiments, the UE determines a time interval associated with the first type of DSR.

[0147] In other embodiments, the UE determines at least two time intervals associated with the second type of DSR.

[0148] In practical implementation, there are multiple ways for the UE to determine at least one time interval associated with the DSR, and the implementation is not limited to any of the following:

[0149] Method 1: Determine at least one time interval of DSR based on the number of thresholds.

[0150] For example, determining at least one time interval of DSR based on the number of thresholds may include at least one of the following:

[0151] Based on the number of thresholds n and the first threshold corresponding to the triggering event, determine n+1 time intervals associated with the second type of DSR. The m-th time interval can be any two adjacent values ​​in the order of 0, n thresholds and the first threshold in size sorted; m can be a positive integer less than or equal to n+1.

[0152] Based on the number of thresholds, determine the n time intervals associated with the second type of DSR. The m-th time interval can be 0 or any two adjacent values ​​of the n thresholds in order of size; m can be a positive integer less than or equal to n.

[0153] Method 2: Determine at least one time interval associated with DSR based on the threshold.

[0154] In some embodiments, the threshold here may be configured by the network device or agreed upon by a protocol. For example, the threshold is configured by DSR configuration information.

[0155] In some embodiments, if the network device configures X thresholds for the UE, then two adjacent values ​​of the X thresholds can form a time interval. In this way, if the largest threshold of the X thresholds is less than the first threshold, X+1 thresholds can be formed.

[0156] Method 3: Determine at least one time interval of the DSR based on a first threshold for sending the DSR report.

[0157] 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. For example, if the network device configuration or protocol specifies the duration of each time interval, then, given a first threshold, at least one time interval associated with the DSR can be determined using the first threshold and the predetermined duration. For instance, assuming the duration of a single time interval is specified as 2ms, and the first threshold is equal to 8ms, then there are a total of four time intervals: 0–2ms, 2–4ms, 4–6ms, and 6–8ms.

[0158] In other embodiments, at least one time interval of the DSR is determined based on the first threshold and the number of intervals. For example, if the network device configures X thresholds for the UE, and the largest of these X thresholds is equal to the first threshold, then X thresholds can be constituted. As another example, the network device configuration or protocol can specify the number of protocol time intervals, which the UE determines based on the number of time intervals and the first threshold. For instance, assuming the network device configuration or protocol specifies Y time intervals, then 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.

[0159] In some embodiments, the number of intervals is determined by a protocol, or the number of intervals is configured by the network device. In summary, in some cases, the plurality of time intervals depends on the number of thresholds; or, the plurality of time intervals depends on both the trigger threshold and the number of intervals.

[0160] S2102: The UE sends a DSR to the network device.

[0161] In some embodiments, the network device may be an access network device, which may include, but is not limited to, an eNB and / or a gNB.

[0162] In some embodiments, when at least one LCG triggering event is detected, the UE sends a DSR to the network device. For example, if it is detected that the remaining duration of at least one LCG is less than a first threshold, the UE sends a DSR to the network device.

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

[0164] In some embodiments, the UE sends a second type of DSR to the network device.

[0165] In some embodiments, the UE sends a first type DSR and a second type DSR to the network device.

[0166] In some embodiments, the UE sends a first type DSR or a second type DSR to the network device according to network instructions.

[0167] In some embodiments, the network device sends a first type DSR or a second type DSR to the network device based on the type of DSR associated with the detected triggering event.

[0168] In some embodiments, the network device detects triggering events for a first type of DSR and a second type of DSR, respectively, and sends either the first type of DSR or the second type of DSR to the network device according to a local policy. For example, according to a second type of DSR priority policy, the second type of DSR is sent to the network device first; according to a second type of DSR indication reporting policy, if no specific indication is detected requiring the use of a second type of DSR, the first type of DSR is sent to the network device first.

[0169] In some embodiments, the association between the first type of DSR and the second type of DSR can also be indicated in the message carrying the first type of DSR and the second type of DSR. For example, the DSR is carried in the MAC CE.

[0170] In some embodiments, the first type of DSR and the second type of DSR are carried in different Media Access Control (MAC) control units (CEs). 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 use different communication resources for transmission. 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 can ignore the currently reported DSR type and use the MAC CE shared by the first type of DSR and the second type of DSR to send the DSR that needs 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 use based on the type of DSR to be reported.

[0171] In some embodiments, the first type DSR and the second type DSR for the same LCG can be carried in the same or different MAC CEs and sent to the network device.

[0172] In some embodiments, Type I and Type II DSRs from different LCGs can be carried and reported in the same MAC CE. In this case, the DSRs carried by a MAC CE may include Type I and Type II DSRs from different LCGs.

[0173] In some embodiments, Type I and Type II DSRs from different LCGs can be carried and reported in different MAC CEs. In this case, a DSR carried by a MAC CE may include Type I DSRs from different LCGs. Alternatively, a DSR carried by a MAC CE may include Type II DSRs from different LCGs.

[0174] In some embodiments, the first type of DSR may carry one reporting field; for example, the second type of DSR may carry one reporting field of an LCG. In other embodiments, the second type of DSR may carry multiple reporting fields; for example, the second type of DSR may carry one or more reporting fields of an LCG. The reporting fields here can be used to carry delay status information.

[0175] In some embodiments, one of the multiple reporting fields included in the second type of DSR carries the BS value of the PDU to be transmitted whose remaining duration is within the time interval associated with that reporting field. For example, assuming there are 3 time intervals, if reporting field A is associated with time interval 2, then the BS value carried by reporting field A is the BS value of the data to be transmitted whose remaining duration is within time interval 2.

[0176] In other embodiments, the second type of DSR includes multiple reporting fields, one of which carries the BS value of the data to be transmitted whose remaining duration is below the upper limit of the time interval associated with that reporting field. For example, assuming there are 3 time intervals, if reporting field A is associated with time interval 2, then the BS value carried by reporting field A is the BS value of the data to be transmitted whose remaining duration is in time interval 2 and whose remaining duration is in time interval 1. The value in time interval 1 is less than the value in time interval 2.

[0177] In some embodiments, the reporting fields for the second type of DSR can be divided into two main categories: a first type of reporting field and a second type of reporting field. For example, the second type of DSR may include a first type of reporting field and / or a second type of reporting field.

[0178] In some embodiments, a 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.

[0179] In some embodiments, the first information is information that explicitly indicates the remaining duration, typically occupying one or more bits.

[0180] In some embodiments, the first information is duration information. This duration information is used to indicate the minimum remaining duration, maximum remaining duration, or average remaining duration of PDUs within a first interval.

[0181] In other embodiments, the first information may be a range index, which indicates the time range in which the remaining duration of the BS value lies.

[0182] In some embodiments, the number of first-type reporting fields in 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-type reporting fields in 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 in that LCG belongs. For example, the number of first-type reporting fields included in the DSR is equal to the number of time intervals in which PDUs with remaining duration less than a first threshold are located.

[0183] In some embodiments, the first type of reporting field further includes a first indication field.

[0184] In some embodiments, the first indication field is used by the network device to determine the number of first-type reporting fields contained in an LCG or the number of first-type reporting fields contained in a DSR.

[0185] In some embodiments, the first indication field is used to indicate whether there is an (n+1)th first type reporting field after the nth first type reporting field.

[0186] For example, the first n first-type reporting fields are associated with n first indication fields, where the nth first indication field indicates whether there is an (n+1)th first-type reporting field after the nth first reporting field. The n first-type reporting fields associated with the n first indication fields can belong to the same octet or two adjacent octets. Exemplarily, one first-type reporting field can correspond to one first indication field. Exemplarily, the first indication field may include reserved bits for the DSR.

[0187] In some embodiments, the first indication field may include one or more additional octets for indicating the number of first-type reporting fields contained in a DSR or an LCG. These additional octets may be specifically used to determine the number of first-type reporting fields contained in a DSR or an LCG.

[0188] In some embodiments, the second type of reporting field includes the BS value but does not contain the first information. That is, the second type of reporting field does not contain information that explicitly indicates the remaining duration. The second type of reporting field saves the bit overhead of the first information.

[0189] In some embodiments, if the DSR includes a second type of reporting field, the multiple second type of reporting fields are sorted in descending order of the time interval values, or in ascending order of the time interval values, or in a specified order of importance (in which case the order is independent of the size of the time interval values).

[0190] In some embodiments, the number of second-class reporting fields of an LCG included in the DSR is equal to the number of time intervals associated with the DSR.

[0191] In some embodiments, if the remaining duration of no data falls into a certain time interval, the BS value corresponding to that time interval is 0, and the value 0 is carried in the corresponding second type of reporting field of DSR.

[0192] In some embodiments, a second type of reporting field may contain fewer bits than a first type of reporting field. For example, a second type of reporting field may include one octet, while a first type of reporting field may include two octets.

[0193] Of course, in some cases, the first indication field can be omitted from a DSR containing second-type reporting fields. For example, the number of second-type reporting fields in a DSR is related to the number of LCGs (Local Time Groups) that the DSR needs to report delay status information. Thus, when a network device receives a DSR carrying second-type reporting fields, 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 LCGs indicating the delay status information to be reported in the LCG fields. This allows the network device to quickly decode the DSR.

[0194] In some embodiments, a DSR containing a second type of reporting field may also carry a first indication field, which may further explicitly indicate the number of second type of reporting fields contained in a DSR or an LCG.

[0195] In some embodiments, the DSR may also include a second indication field. Exemplarily, both the first type of reporting field and / or the second type of reporting field may include a second indication field.

[0196] In some embodiments, the second indication field is used to indicate the table referenced for calculating the BS value. Different tables have different methods for calculating the BS value, so the same PDU to be transmitted may have different determined BS values ​​if different tables are used. For example, different tables are used for different degrees of quantization of the BS value.

[0197] In some embodiments, multiple reporting fields within an LCG may refer to the same table or different tables, preferably the same table. Reporting fields from different LCGs within a DSR may refer to the same table or different tables, preferably the same table. When multiple reporting fields of an LCG refer to the same table, an LCG may correspond to a second indicator field. This second indicator field determines whether the tables referenced by the multiple reporting fields of that LCG are the same, rather than associating one reporting field with one second indicator field, thus saving bit overhead on reporting fields. In some embodiments, second indicator fields may also be divided into two categories: one for the entire DSR and the other for LCGs. For example, in the case of a second indicator field for the entire DSR, where all LCG groups reported by the DSR refer to the same table, the second indicator field associated with the LCG can be omitted, thus saving bit overhead. When different LCGs refer to different tables, the second indicator field for each LCG is retained to indicate the table referenced by each LCG.

[0198] In this embodiment of the disclosure, when the UE sends a DSR, the network device will receive the corresponding DSR and decode it according to the DSR format, thereby scheduling radio resources for the UE based on the delay status information of each LCG reported by the DSR.

[0199] As shown in Figure 3, this embodiment of the disclosure provides a DSR transmission method, executed by a UE. The method may include:

[0200] S3101: Determine at least one time interval associated with DSR.

[0201] In some embodiments, the optional method by which the UE determines at least one time interval associated with the DSR can be found in the relevant description of step S2101 of the embodiment corresponding to FIG2.

[0202] S3102: Send DSR.

[0203] In some embodiments, the UE sends a DSR to the network device.

[0204] In some embodiments, the optional method by which the UE determines at least one time interval associated with the DSR can be found in the relevant description of step S2102 of the embodiment corresponding to FIG2.

[0205] It is worth noting that any one of S3101 to S3102 can be implemented independently, and S3101 and S3102 can also be implemented in combination. For example, if the UE determines at least one time interval associated with the DSR, but does not detect a DSR trigger event, then it does not need to send the DSR. As another example, if the UE already knows at least one time interval associated with the DSR in advance, it can skip this step and proceed to the execution of S3102.

[0206] As shown in Figure 4, this embodiment of the disclosure provides a DSR transmission method, executed by a network device. The method may include:

[0207] S4101: Receive DSR.

[0208] In some embodiments, the network device receives a DSR sent by the UE.

[0209] For example, the relevant description of the DSR can be found in the embodiment corresponding to Figure 2.

[0210] In some embodiments, after receiving the DSR, the network device parses the DSR according to its format. After obtaining the delay status information of each LCG reported by the UE, the device performs corresponding radio resource scheduling.

[0211] This disclosure introduces a second type of DSR. This second type of DSR can carry one or more sets of remaining duration information and BS values. For example, the second type of DSR can carry one or more reporting fields, and each reporting field can carry one set of remaining duration information and BS values.

[0212] For example, the remaining duration information and BS value of the same group point to the same time interval with remaining duration. For instance, if group A is associated with time interval 1, then 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 for PDUs with remaining duration in time interval 1. The BS value of group A indicates the amount of data for all PDUs with remaining duration in time interval 1.

[0213] In some embodiments, a Type 2 DSR for an LCG may carry one or more reporting fields. These reporting fields may be remaining time and buffer size fields.

[0214] In some embodiments, 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.

[0215] The following will determine the relevant attributes or characteristics of the second type of DSR from multiple aspects.

[0216] Firstly, the determination of the time interval.

[0217] The UE determines the time interval according to the network configuration and / or protocol agreement.

[0218] Example 1: Determining time intervals based on thresholds. For example, the number of time intervals and / or the upper and lower limits of the time intervals can be determined based on the number of thresholds. In this case, the network device is configured with multiple thresholds, and the UE determines the time intervals based on these multiple thresholds. The UE can also determine the time intervals based on multiple thresholds agreed upon in the protocol.

[0219] In some embodiments, the number of time intervals associated with the second type of DSR is equal to the number of thresholds, and the range of values ​​for the time intervals can be determined based on two adjacent thresholds sorted by size.

[0220] For example, according to network device configuration or protocol agreement, the thresholds used for Type II DSR include: threshold 1 and threshold 2. In this case, the number of time intervals associated with Type II DSR can be used, where the two time intervals are 0 to threshold 1 and threshold 1 to threshold 2, respectively.

[0221] Example 2: The network device configures the number of time intervals or the protocol defines the number of time intervals. Based on the number of time intervals and the trigger threshold for DSR reporting by the UE, the value range of each time interval is determined. For example, assuming the number of time intervals is 2 and the trigger threshold is 10ms, then according to the equal division strategy, the value range of interval 1 is determined to be 0-5ms, and the value range of interval 2 is determined to be 5-10ms. As another example, assuming the number of time intervals is 3 and the trigger threshold is 6ms, then according to the equal division strategy, the UE can determine 3 time intervals: interval 1 is 0-2ms, interval 2 is 2ms-4ms, and interval 3 is 4ms-6ms.

[0222] In some embodiments, the strategy for determining the value range of each time interval based on the number of intervals is not limited to an equal division strategy. In some embodiments, it can also be determined based on 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 based on the ratio. For example, assuming the trigger threshold is 8ms, the number of intervals is 3, and the ratio is 1:2:1, then the value ranges of the 3 time intervals are respectively: 0~2ms, 2ms~6ms, and 6ms~8ms.

[0223] Example 3: The number of time intervals configured by the network device or the number of time intervals agreed upon by the protocol, and the thresholds agreed upon by the network device or the protocol. In this case, the UE can determine the number of time intervals and the value range of each time interval based on the number of intervals, the thresholds, and the trigger thresholds.

[0224] For example, the protocol specifies the number of intervals, such as 3, and sets two thresholds. In this case, the three intervals are 0 to threshold 1, threshold 1 to threshold 2, and threshold 2 to the trigger threshold, respectively. The above describes three methods for determining time intervals.

[0225] In some embodiments, for an LCG, a second type of DSR can also be associated with a time interval. For example, for an LCG, a time interval less than the trigger threshold is determined to be associated with the second type of DSR, while the amount of PDUs with remaining duration greater than the trigger threshold can be reported within a time interval not associated with the second type of DSR and exceeding the trigger threshold.

[0226] In some embodiments, if only one time interval is set for an LCG, the first type of DSR can also be used to report delay status information.

[0227] Secondly, the BS value can be calculated as follows:

[0228] Method 1: The UE counts the BS values ​​to be reported by time interval.

[0229] In this approach, after triggering DSR reporting, the UE carries at least one set of delay status information for each LCG. This set of delay status information consists of a BS value, or corresponding remaining duration information and BS settings. For example, the DSR may include one or more reporting fields. A reporting field can be used to report a set of delay status information. Different reporting fields correspond to different time intervals with different value ranges. Before reporting the DSR, the UE calculates the data based on the remaining duration of the PDU, i.e., it calculates the BS value for each time interval.

[0230] For example, if the trigger threshold of DSR is 6ms, then the BS values ​​reported by DSR in each time interval below 6ms can be as shown in Table 1.

[0231] Table 1

[0232] Method 2: The UE calculates the amount of data corresponding to each time interval based on the inclusion relationship between time intervals.

[0233] Table 2

[0234] 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. The gNB needs to perform a calculation to obtain the data volume for each interval. If this method is used, the network device, after receiving the DSR, determines the specific data volume within each time interval based on the inclusion relationship between the various BS values ​​and time intervals.

[0235] After determining the BS value as shown in Table 1 or Table 2, the information carrying methods for the reporting fields in the DSR are as follows:

[0236] The first method is for the UE to display the delay status information for each group. For example, the DSR can carry information through three reporting fields: {2ms, Xbit}; {4ms, Ybit}, {6ms, Zbit}; or {2ms, Xbit}; {4ms, X+Ybit}, {6ms, X+Y+Zbit}.

[0237] The second method: The UE can indicate the time interval through a range index. For example, the DSR can carry information through three reporting fields: {0, Xbit}; {1, Ybit}, {2, Zbit}; or {0, Xbit}; {1, X+Ybit}, {2, X+Y+Zbit}. Indicating the time interval through a range index reduces the bit overhead compared to directly using the remaining duration information.

[0238] The third approach: The UE does not report remaining duration information or interval indexes. For example, the DSR can report the BS values ​​for each time interval through three ordered reporting fields. For instance, the DSR can use three reporting fields to carry information: {X bit}, {Y bit}, {Z bit}, or {X bit}; {X+Y bit}, {X+Y+Z bit}. The sorting method for each time interval can be agreed upon by the UE and the network device. For example, it can be sorted from largest to smallest, smallest to largest, or by a specified importance. For example, a sorting based on importance could 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, suggested by the UE, or agreed upon by the protocol. Using this method can further reduce the signaling overhead of the DSR.

[0239] As an example, the UE counts data based on the remaining duration of the PDU in intervals: however, the value of the remaining duration information is still the minimum, maximum, or average of the remaining duration of the PDU within that interval.

[0240] For example, taking the remaining time information in Table 1 as an example, assuming that X bits, which is the amount of data, has a remaining time in the range of 0-2ms, but the minimum remaining time is 1.5ms; Y bits, which is the amount of data, has a remaining time in the range of 2-4ms, but the minimum remaining time is 2.5ms; and Z bits, which is the amount of data, has a remaining time in the range of 4-6ms, but the minimum remaining time is 4.5ms.

[0241] Examples of the content carried by these three reporting fields can be shown in Table 3 or Table 4:

[0242] Table 3

[0243] Table 4

[0244] If no data meeting the conditions is detected in a certain time interval, there is no need to have a reporting field for that interval or the reporting BS value should be set to 0.

[0245] In some embodiments, there are multiple reporting fields in the DSR, and the value of BT can be reused, or each reporting field can use its own different BT.

[0246] As shown in Figure 1B, if LCGi = 1, it indicates that the current DSR contains delay status information for that LCGi. This DSR can carry one or more reporting fields. The introduction of the first indicator field indicates whether there are any subsequent reporting fields after the current reporting field, facilitating rapid resolution by network devices.
