For multi-modality (MM) services, the data of each sub-service can be mapped to different Quality of Service (QoS) flows. These QoS flows often have certain correlations; for example, the relative latency between these QoS flows needs to be less than a certain threshold to ensure synchronization. However, in related technologies, there is still no corresponding solution for how to transmit the correlated objects (e.g., data packets, data packet sets, or QoS flows) of MM services.

[0059] For ease of understanding, the following describes some aspects of the embodiments of this application:

[0060] I. DSR reporting mechanism based on Packet Delay Budget (PDB):

[0061] Related technologies introduce a PDB-based DSR reporting mechanism. For each Packet Data Convergence Protocol (PDCP) Service Data Unit (SDU) received from a higher layer, the transmitting end starts a discard timer. When this timer expires, the PDCP SDU is deleted. To avoid PDCP SDU deletion due to transmission / scheduling delays at the transmitting end, the network side configures a remaining time threshold for each Logical Channel Group (LCG) of the UE. When the remaining time before the UE's PDCP discard timer expires is less than or equal to the network-configured remaining time threshold, the UE triggers DSR reporting. The UE calculates the amount of delay-critical data in the buffer and the remaining time, and fills it into the Media Access Control Element (MAC CE) before reporting it to the gNB. The MAC CE format can be shown in Figure 2.

[0062] Where LCGi is set to 1, it means that the LCG reports latency-sensitive data. BT represents the buffer size table used. Remaining time represents the shortest remaining time in the LCG, in milliseconds. Buffer size represents the amount of data in the LCG whose remaining time is below the remaining time threshold.

[0063] The transmission method provided in this application will be described in detail below with reference to the accompanying drawings, through some embodiments and application scenarios.

[0064] Please refer to Figure 3, which is a flowchart of a transmission method provided in an embodiment of this application. This method can be executed by a terminal, and as shown in Figure 3, it includes the following steps:

[0065] Step 301: If the first object and the second object meet the first condition, the terminal reports a status report;

[0066] The status report includes at least one of DSR and BSR, and the first condition includes one of the following: the relative delay between the first object and the second object is greater than or equal to RDB; the remaining time of RDB between the first object and the second object is less than or equal to a first time threshold; the relative delay between the first object and the second object is greater than or equal to a second time threshold; the first object and the second object have an association relationship; and the first object or the second object includes a data packet, a set of data packets, or a QoS flow.

[0067] The first object and the second object mentioned above can include any two objects that are related. The number of the first objects can be at least one, and the number of the second objects can also be at least one.

[0068] For example, when the first object and the second object are QoS flows, the association between the first object and the second object can be determined based on the Multi-Modality Service Identifier (MMSID) associated with the first object and the MMSID associated with the second object. For example, if the MMSID associated with the first object and the MMSID associated with the second object are the same, it indicates that the first object and the second object are associated. When the first object and the second object are data packets or a set of data packets, the association between the first object and the second object can be determined based on the header of the first object and the header of the second object. For example, if the header of the first object includes the same indication for the association and the header of the second object both include the same indication for the association, it indicates that the first object and the second object are associated.

[0069] The aforementioned first time threshold can also be called the remaining time threshold. The aforementioned first time threshold is less than the aforementioned RDB. The remaining time of the RDB between the aforementioned first object and the second object can be the difference between the RDB between the aforementioned first object and the second object and the relative delay between the aforementioned first object and the second object.

[0070] The second time threshold is less than the RDB. For example, the second time threshold can be the difference between the RDB and the first time threshold.

[0071] The aforementioned RDB can be configured by the network-side device. At least one of the aforementioned first time threshold and second time threshold can be configured by the network-side device, or can be determined by the terminal. For example, the terminal can determine the second time threshold based on the RDB and the first time threshold.

[0072] For example, the DSR mentioned above may include at least one of the following: the remaining time of the RDB corresponding to the object that does not meet the first condition, the amount of data of the object that does not meet the first condition, etc. The BSR mentioned above may include at least one of the following: the remaining time of the RDB corresponding to the object that does not meet the first condition, the amount of data of the object that does not meet the first condition, etc. For instance, the DSR mentioned above may include the remaining time of the RDB corresponding to the object that does not meet the first condition, and the BSR mentioned above may include the amount of data of the object that does not meet the first condition.

[0073] For example, when the first object and the second object meet the first condition, the terminal reports a status report, and then the network-side device can adjust the scheduling of the slower-transmitting object among the first object and the second object based on the status report to ensure the relative latency requirements of the first object and the second object.

[0074] In this embodiment, when the first object and the second object meet a first condition, the terminal reports a status report; wherein the status report includes at least one of DSR and BSR, and the first condition includes the following: the relative delay between the first object and the second object is greater than or equal to RDB, the remaining time of RDB between the first object and the second object is less than or equal to a first time threshold, and the relative delay between the first object and the second object is greater than or equal to a second time threshold; the first object and the second object have an association relationship, and the first object or the second object includes a data packet, a data packet set, or a QoS flow. That is, this embodiment can trigger the reporting of at least one of the delay status report and the data status report based on the relevant delay between the associated objects, which is beneficial to assisting the network-side device in scheduling the associated objects, and thus helps to ensure the relative delay requirements between the associated objects.

[0075] Optionally, the DSR or BSR includes at least one of the following:

[0076] The first remaining time is determined based on the remaining time of the RDB corresponding to the target object;

[0077] The first cache size is determined based on the amount of data of the target object;

[0078] The target object is the one that transmits more slowly between the first object and the second object.

[0079] The target object mentioned above is the object with slower transmission between the first object and the second object. In other words, the target object refers to the object with slower transmission among the two objects that meet the first condition.

[0080] For example, in the case of a QoS flow, it can be compared and To determine the slower-transmitting object between the first and second objects, for example, if This indicates that the second object is the object with slower transmission speed, meaning the target object is the second object; if This indicates that the first object is the slower-transmitting object, meaning the target object is the first object; where X represents the PBR of the first object, Y represents the PBR of the second object, x1 represents the transmission rate of the first object, and y1 represents the transmission rate of the second object. When the object is a data packet or a set of data packets, the slower-transmitting object can be determined based on the scheduling time of the first and second objects. For example, if the first object is scheduled before the second object, then the second object is the slower-transmitting object, meaning the target object is the second object; conversely, if the second object is scheduled before the first object, then the first object is the slower-transmitting object, meaning the target object is the first object.

[0081] In one embodiment, the status of objects that meet the first condition (i.e., target objects) and the status of objects that meet the second condition (i.e., third objects) can be statistically reported separately. In this embodiment, the first remaining time can be determined solely based on the remaining time of the RDB corresponding to the target object, and the first cache size can also be determined solely based on the amount of data of the target object.

[0082] In another embodiment, the status of objects that meet the first condition (i.e., the target object) and the status of objects that meet the second condition (i.e., the third object) can be reported by comprehensively statistically analyzing the status of the objects that meet the first condition (i.e., the target object) and the status of the objects that meet the second condition (i.e., the third object). In this embodiment, if there is a third object that meets the second condition, the first remaining time can be determined based on the remaining time of the RDB corresponding to the target object and the remaining time of the PDB of the third object. The first cache size can also be determined based on the data volume of the target object and the data volume of the third object.

[0083] Optionally, the first remaining time is the minimum value among the remaining times of the RDBs corresponding to all target objects within the first logical channel group (LCG).

[0084] And / or, the first cache size is the sum of the data amounts of all target objects within the first LCG;

[0085] Wherein, the first LCG can be any LCG.

[0086] Among them, the first remaining time is greater than 0, that is, the first remaining time is the minimum value of the remaining time of the RDB corresponding to all target objects in the first LCG that is greater than 0.

[0087] The aforementioned first remaining time is the minimum value among the remaining times of the RDBs corresponding to all target objects within the first LCG, which is also the minimum value among the remaining times of the RDBs corresponding to the slower object among all two objects within the first LCG that satisfy the first condition; the aforementioned first cache size is the sum of the data amounts of all target objects within the first LCG, which is also the sum of the data amounts of the slower object among all two objects within the first LCG that satisfy the first condition.

[0088] In this embodiment, the terminal independently reports the status of objects that meet the first condition, i.e., the relative latency status, and reports the status based on the granularity of each LCG (i.e., Per LCG). This makes it easier for the network side to know the relative latency status of each LCG, and thus can prioritize scheduling objects that meet the first condition to ensure the relative latency requirement.

[0089] Optionally, the first object or the second object is a data packet, and the first remaining time is determined based on the remaining time of the RDB corresponding to the target object and the remaining time of the data packet delay budget PDB of the third object;

[0090] And / or,

[0091] The first cache size is determined based on the data volume of the target object and the data volume of the third object;

[0092] The third object is a data packet that meets the second condition, which includes the following: the delay of the data packet is greater than or equal to the PDB, the remaining time of the PDB of the data packet is less than or equal to the third time threshold, and the delay of the data packet reaches the fourth time threshold.

[0093] The third object mentioned above can be any data packet that satisfies the second condition.

[0094] The aforementioned PDB can be configured by the network-side equipment. At least one of the aforementioned third and fourth time thresholds can be configured by the network-side equipment or determined by the terminal.

[0095] In this embodiment, the terminal reports the status of objects satisfying the first condition (i.e., the target object) and the status of objects satisfying the second condition (i.e., the third object) based on comprehensive statistical analysis. It should be noted that if a third object satisfying the second condition exists when both the first and second objects satisfy the first condition, the first remaining time is determined based on the remaining time of the RDB corresponding to the target object and the remaining time of the data packet delay budget PDB of the third object; the first buffer size is determined based on the data volume of the target object and the data volume of the third object. If a third object satisfying the second condition does not exist when both the first and second objects satisfy the first condition, the first remaining time is determined solely based on the remaining time of the RDB corresponding to the target object, and the first buffer size is determined solely based on the data volume of the target object.

[0096] In this embodiment, the status of objects that meet the first condition (i.e., the target object) and the status of objects that meet the second condition (i.e., the third object) are reported together, which helps to save signaling overhead.

[0097] Optionally, the first remaining time is the minimum of the remaining time of the RDB corresponding to all target objects in the first LCG and the remaining time of the PDB of all third objects in the first LCG.

[0098] And / or, the first cache size is the sum of the data volume of all target objects in the first LCG and the target data volume, wherein the target data volume is the data volume of a third object in the first LCG that is different from the target object;

[0099] Wherein, the first LCG can be any LCG.

[0100] Specifically, the first remaining time is greater than 0, meaning it is the minimum of the remaining times greater than 0 among the remaining times of the RDB corresponding to all target objects within the first LCG and the remaining times of the PDB of all third objects within the first LCG. The first cache size is the sum of the data volume of all target objects within the first LCG and the target data volume; that is, the first cache size is the sum of the data volume of all target objects and all third objects within the first LCG after deduplication.

[0101] The aforementioned first remaining time is the minimum of the remaining time of the RDB corresponding to all target objects in the first LCG and the remaining time of the PDB of all third objects in the first LCG. That is, the minimum of the remaining time of the RDB corresponding to the slower object among all two objects that meet the first condition in the first LCG and the remaining time of the PDB of all objects that meet the second condition in the first LCG. The aforementioned first cache size is the sum of the data amount of all target objects in the first LCG and the target data amount. That is, the sum of the data amount of the slower object among all two objects that meet the first condition in the first LCG and the target data amount. The target data amount is the sum of the data amount of objects that are different from the target object among all objects that meet the second condition in the first LCG.

[0102] In this embodiment, delay status reporting is performed at the granularity of each LCG (i.e., Per LCG), which helps to save signaling overhead.

[0103] Optionally, in this embodiment, the terminal may report the status report using a first format MAC CE, wherein the first format MAC CE includes a first field, a second field, and a third field; the first field is used to indicate LCG, the second field is used to indicate remaining time, and the third field is used to indicate cache size.

[0104] In other words, this embodiment can reuse the MAC CE used for DSR reporting in related technologies to transmit the above-mentioned status report, which can not only save air interface overhead, but also simplify the design of status report reporting.

[0105] It should be noted that this implementation method is also applicable to two LCHs that are mapped to different gNBs through a dual-connectivity (DC) configuration. In this case, the terminal needs to distinguish between different LCHs to trigger MAC CE reporting on different gNBs.

[0106] Optionally, the DSR or BSR further includes at least one of the following:

[0107] The second remaining time is determined based on the remaining time of the PDB corresponding to the third object;

[0108] The second cache size is determined based on the amount of data in the third object.

[0109] The third object is a data packet that satisfies the second condition, which includes the following: the delay of the data packet is greater than or equal to the PDB, the remaining time of the PDB of the data packet is less than or equal to the third time threshold, and the delay of the data packet is greater than or equal to the fourth time threshold.

[0110] In this embodiment, if a third object satisfies the second condition when the first object and the second object satisfy the first condition, the status of the third object is independently counted and reported. That is, the second remaining time is determined based on the remaining time of the PDB corresponding to the third object, and the second cache size is determined based on the amount of data of the third object.

[0111] Optionally, the second remaining time is the minimum value among the remaining times of the PDBs corresponding to all third objects within the first LCG;

[0112] And / or, the second cache size is the sum of the data amounts of all third objects within the first LCG;

[0113] Wherein, the first LCG can be any LCG.

[0114] In this embodiment, status reports are submitted at the granularity of each LCG (i.e., Per LCG).

[0115] Among them, the second remaining time is greater than 0, that is, the second remaining time is the minimum value of the remaining time greater than 0 among the remaining times of all PDBs corresponding to the third objects in the first LCG.

[0116] The aforementioned second remaining time is the minimum value among the remaining times of the PDBs corresponding to all third objects within the first LCG, and the aforementioned second remaining time is the minimum value among the remaining times of the PDBs corresponding to all objects within the first LCG that satisfy the second condition. The aforementioned second cache size is the sum of the data volume of all third objects within the first LCG, that is, the aforementioned second cache size is the sum of the data volume of all objects within the first LCG that satisfy the second condition.

[0117] In this embodiment, when there is an object that meets the second condition (i.e., the third object), the data packet delay status of the third object is reported independently, that is, at least one of the second remaining time and the second buffer size mentioned above. This makes it easier for the network side to know the data packet delay status of each LCG, and thus can prioritize scheduling objects that meet the second condition to ensure the data packet delay requirements.

[0118] Optionally, in this embodiment, the terminal may use a second format MAC CE to report the aforementioned status report, wherein the second format MAC CE includes a fourth field, a fifth field, a sixth field, and a seventh field; wherein the fourth field is used to indicate the LCG, the fifth field is used to indicate the remaining time, the sixth field is used to indicate the buffer size, and the seventh field is used to indicate the latency status type, wherein the latency status type includes relative latency status or data packet latency status.

[0119] Specifically, when the latency state type indicated by the seventh field is a relative latency state, the LCG indicated by the fourth field is an LCG that contains an object (i.e., a target object) that satisfies the first condition, the remaining time indicated by the fifth field is the minimum of the remaining times of the RDBs corresponding to all target objects within the LCG, and the buffer size indicated by the sixth field is the sum of the data amounts of all target objects within the LCG; when the latency state type indicated by the seventh field is a packet latency state, the LCG indicated by the fourth field is an LCG that contains an object (i.e., a third object) that satisfies the second condition, the remaining time indicated by the fifth field is the minimum of the remaining times of the PDBs corresponding to all third objects within the LCG, and the buffer size indicated by the sixth field is the sum of the data amounts of all third objects within the LCG.

[0120] Alternatively, in this embodiment, the terminal may report the aforementioned status report using a third-format MAC CE, wherein the MAC CE is a third-format MAC CE, and the third-format MAC CE includes an eighth field, a ninth field, a tenth field, and an eleventh field; wherein the eighth field is used to indicate the LCG corresponding to the relative delay state, the ninth field is used to indicate the LCG corresponding to the data packet delay state, the tenth field is used to indicate the remaining time, and the eleventh field is used to indicate the buffer size. Specifically, the LCG indicated by the eighth field is an LCG in which an object (i.e., a target object) satisfies the first condition. The remaining time indicated by the tenth field corresponding to the eighth field is the minimum of the remaining time of the RDBs corresponding to all target objects in the LCG. The cache size indicated by the eleventh field corresponding to the eighth field is the sum of the data amounts of all target objects in the LCG. The LCG indicated by the ninth field is an LCG in which an object (i.e., a third object) satisfies the second condition. The remaining time indicated by the tenth field corresponding to the ninth field is the minimum of the remaining time of the PDBs corresponding to all third objects in the LCG. The cache size indicated by the eleventh field corresponding to the ninth field is the sum of the data amounts of all third objects in the LCG.

[0121] Alternatively, in this embodiment, the terminal may use a fourth-format MAC CE to report the aforementioned status report, wherein the MAC CE is a fourth-format MAC CE, and the fourth-format MAC CE includes a twelfth field, a thirteenth field, a fourteenth field, and a fifteenth field; wherein the twelfth field is used to indicate the LCG, the thirteenth field is used to indicate the threshold index for triggering the delay status report, the fourteenth field is used to indicate the remaining time, and the fifteenth field is used to indicate the cache size. For example, each threshold index can correspond to a set of indication fields, which includes a twelfth field, a fourteenth field, and a fifteenth field. The parameters of each set of indication fields are determined based on the threshold indicated by its corresponding threshold index. For example, if the threshold A indicated by threshold index a is the threshold that triggers relative delay status reporting, then the LCG indicated by the twelfth field corresponding to threshold index A is the LCG that triggers relative delay status reporting by threshold A. The remaining time indicated by the fourteenth field corresponding to threshold index A is the minimum value of the remaining time of the RDB corresponding to all target objects in the LCG. The cache size indicated by the fifteenth field corresponding to threshold index A is the sum of the data volume of all target objects in the LCG. The target objects in the LCG are determined according to the aforementioned threshold A.

[0122] Optionally, the status report reported by the terminal includes:

[0123] The terminal reports its status via the Media Access Control Unit (MAC CE).

[0124] Optionally, the MAC CE is a first format MAC CE, which includes a first field, a second field, and a third field;

[0125] The first field indicates the LCG, the second field indicates the remaining time, and the third field indicates the cache size.

[0126] For example, the first field may include N LCG indicator bits, which may correspond to N LCGs respectively, where N is a positive integer, for example, N is 8. Each LCG indicator bit with a value of 1 may correspond to a first indicator field, and a first indicator field includes a second field and a third field.

[0127] For example, the MAC CE of the first format described above can be as shown in Figure 4a, wherein setting LCGi to 1 indicates that the LCG contains at least one of the objects that satisfy the first condition and the objects that satisfy the second condition, BT represents the buffer size table used, the remaining time represents the minimum remaining time of the objects that satisfy the first condition and the objects that satisfy the second condition within the LCG, in milliseconds, and the buffer size represents the amount of data of the objects that satisfy the first condition and the objects that satisfy the second condition within the LCG.

[0128] Understandably, in LCG i The LCG is defined only if an object satisfying the first condition (i.e., the target object) exists. i The corresponding remaining time domain is LCG i The minimum remaining time of the RDB corresponding to all target objects within the LCG that is greater than 0 is the LCG. i The corresponding cache size range is LCG. i The sum of the data volume of all target objects within the LCG; i The LCG is defined only if an object satisfying the second condition (i.e., the third object) exists. i The corresponding remaining time domain is LCG i The minimum remaining time among all PDBs corresponding to third objects within the LCG. i The corresponding cache size range is LCG. i The sum of the data volume of all third objects within the LCG; i If there exists an object that satisfies the first condition (i.e., the target object) and an object that satisfies the second condition (i.e., the third object), then this LCG... i The corresponding remaining time domain is LCG i The minimum of the remaining time of the RDB corresponding to all target objects and the remaining time of the PDB corresponding to all third objects within the LCG is the value of this LCG. i The corresponding cache size range is LCG. i The sum of the data volume of all target objects and third objects within the scope after deduplication.

[0129] For example, when the terminal reports the status of objects that meet the first condition (i.e., the target object) and the status of objects that meet the second condition (i.e., the third object) based on comprehensive statistical analysis, the terminal can report the status based on the MAC CE in the first format described above.

[0130] This embodiment reports the status report based on the first format MAC CE described above, which not only saves air interface overhead but also simplifies the design of status report reporting.

[0131] Optionally, the MAC CE is a second format MAC CE, which includes a fourth field, a fifth field, a sixth field, and a seventh field;

[0132] The fourth field indicates the LCG, the fifth field indicates the remaining time, the sixth field indicates the buffer size, and the seventh field indicates the latency status type, which includes relative latency status or data packet latency status.

[0133] The relative delay states described above are used to indicate delay states triggered by relative delay, such as the delay state triggered when an RDB is about to expire. The data packet delay states described above are used to indicate delay states triggered by data packet delay, such as the delay state triggered when a PDB is about to expire.

[0134] The aforementioned seventh field can be a newly added bit in the MAC CE, or the aforementioned seventh field can be a reserved (R) bit in the MAC CE used for reporting DSR in related technologies. For example, the R bit of the MAC CE shown in Figure 2 can be used to indicate the delay state type.

[0135] For example, the fourth field may include N LCG indicator bits, which may correspond to N LCGs respectively, where N is a positive integer, for example, N is 8. Each LCG indicator bit with a value of 1 may correspond to a second indicator field, and a second indicator field includes a fifth field, a sixth field, and a seventh field.

[0136] For example, the MAC CE of the second format described above can be as shown in Figure 4b, where type (T) represents the delay state type. For example, T=0 represents the data packet delay state, and T=1 represents the relative delay state. If T represents the relative delay state, then its corresponding LCG... i Setting it to 1 indicates that the LCG i If an object (i.e., the target object) exists that satisfies the first condition, BT represents the buffer size table used, and the remaining time represents the LCG. i The minimum remaining time of the RDB corresponding to all target objects within the LCG, in milliseconds. The buffer size represents the LCG's... i The sum of the data volume of all target objects within; if T represents the relative time delay state, then its corresponding LCGi is set to 1, indicating that the LCG... iThere exists an object that satisfies the second condition (i.e., the third object). BT represents the buffer size table used, and the remaining time represents the LCG. i The minimum remaining time of the PDB corresponding to all third objects within the LCG, in milliseconds. The buffer size represents the LCG's... i The sum of the data volume of all third-party objects within it.

[0137] For example, when the terminal reports the status of objects that meet the first condition (i.e., the target object) and the status of objects that meet the second condition (i.e., the third object) respectively, the terminal can report the status report based on the MAC CE in the second format described above.

[0138] In this embodiment, the seventh field of the MAC CE in the third format indicates the latency status type, which not only makes it easier for the network side to distinguish the latency status type reported by the terminal, but also saves the resource overhead of status report reporting.

[0139] Optionally, the MAC CE is a third-format MAC CE, which includes an eighth field, a ninth field, a tenth field, and an eleventh field.

[0140] The eighth field indicates the LCG corresponding to the relative delay state, the ninth field indicates the LCG corresponding to the data packet delay state, the tenth field indicates the remaining time, and the eleventh field indicates the buffer size.

[0141] For example, both the eighth and ninth fields mentioned above can include N LCG indicator bits, which can correspond to N LCGs respectively, where N is a positive integer, for example, N is 8. Each LCG indicator bit with a value of 1 can correspond to a third indicator field, and a third indicator field includes a tenth field and an eleventh field.

[0142] The eighth field mentioned above is used to indicate the LCG corresponding to the relative delay state. The remaining time indicated by the tenth field corresponding to the eighth field is the minimum value of the remaining time of the RDB corresponding to all target objects in the LCG. The cache size indicated by the eleventh field corresponding to the eighth field is the sum of the data volume of all target objects in the LCG.

[0143] The ninth field mentioned above is used to indicate the LCG corresponding to the packet delay status. The remaining time indicated by the tenth field corresponding to the ninth field is the minimum remaining time of the PDB corresponding to all third objects in the LCG. The buffer size indicated by the eleventh field corresponding to the ninth field is the sum of the data volume of all third objects in the LCG.

[0144] For example, the MAC CE in the third format described above can be as shown in Figure 4c, where the LCG in the first row... i Setting it to 1 indicates that the LCG i There exists an object (i.e., the target object) that satisfies the first condition, and the LCG in the first row is... j Setting it to 1 indicates that LCGj contains an object that satisfies the second condition (i.e., the third object). BT represents the buffer size table used. LCG i The corresponding remaining time indicates the LCG. i The minimum remaining time of the RDB corresponding to all target objects within the LCG. i The corresponding buffer size represents the LCG. i The sum of the data volume of all target objects within; LCG j The corresponding remaining time indicates the LCG. j The minimum remaining time of the PDB corresponding to all third objects within the LCG. j The corresponding buffer size represents the LCG. j The sum of the data volume of all third-party objects within it.

[0145] It should be noted that if the aforementioned status report includes both the relative latency status and the data packet latency status, the order in which the relative latency status and data packet latency status are arranged in the status report can be determined according to the protocol or the network-side device configuration. For example, it can be agreed by protocol to arrange the relative latency status of all LCGs first, and then arrange the data packet latency status of all LCGs; or, it can be agreed by protocol to arrange the relative latency status and data packet latency status of the same LCG together, wherein the order in which the relative latency status and data packet latency status of the same LCG are arranged can also be agreed by protocol, for example, arranging the relative latency status first, then the data packet latency status; or, arranging the data packet latency status first, then the relative latency status.

[0146] For example, when the terminal reports the status of objects that meet the first condition (i.e., the target object) and the status of objects that meet the second condition (i.e., the third object) respectively, the terminal can report the status report based on the MAC CE in the third format described above.

[0147] In this embodiment, the relative latency status and data packet latency status of LCG can be reported separately through the third format MAC CE. This not only allows the network side to obtain different types of latency status, but also makes it easier to distinguish the various types of latency status reported by the terminal, which is convenient for the network side to perform scheduling.

[0148] Optionally, the MAC CE is a fourth-format MAC CE, which includes a twelfth, thirteenth, fourteenth, and fifteenth domains.

[0149] The twelfth field is used to indicate the LCG, the thirteenth field is used to indicate the threshold index for triggering delay status reporting, the fourteenth field is used to indicate the remaining time, and the fifteenth field is used to indicate the cache size.

[0150] The aforementioned threshold indexes are used to indicate thresholds. The aforementioned thirteenth field can be used to indicate K threshold indices, where K is a positive integer, for example, K is 8. The aforementioned K threshold indices may include at least one threshold index corresponding to a relative delay state and at least one threshold index corresponding to a data packet delay state. For example, the 8 threshold indices indicated by the aforementioned thirteenth field may include 1 threshold index corresponding to a relative delay state and 7 threshold indices corresponding to a data packet delay state; or, the 8 threshold indices indicated by the aforementioned 8 threshold indication bits may include 3 threshold indices corresponding to a relative delay state and 5 threshold indices corresponding to a data packet delay state.

[0151] The thresholds indicated by the threshold indices corresponding to the relative delay states may include the aforementioned RDB, the first time threshold, or the second time threshold. For example, the thresholds indicated by the three threshold indices corresponding to the relative delay states may include the first time threshold a1, the first time threshold a2, and the first time threshold a3.

[0152] The thresholds indicated by the threshold indices corresponding to the packet delay state may include the aforementioned PDB, the third time threshold, or the fourth time threshold. For example, the thresholds indicated by the five threshold indices corresponding to the relative delay state may include the third time threshold b1, the third time threshold b2, the third time threshold b3, the third time threshold b4, and the third time threshold b5.

[0153] For example, the MAC CE of the fourth format described above can be as shown in Figure 4d, wherein Thre k Setting it to 1 indicates that the Thre exists. k The delayed status report is triggered, and the value of k ranges from [1, 8]. k Corresponding LCG i Setting it to 1 indicates that the LCG i There exists a Thre k Triggered latency status reporting, BT indicates the buffer size table used, LCG i The corresponding remaining time indicates the LCG. iInternally based on the above Thre k Given the determined remaining time, the aforementioned LCG i The corresponding buffer size represents the LCG. i Internally based on the above Thre k A defined amount of data, for example, if the above Thre k To correspond to the threshold of the relative time delay state, the above LCG i The corresponding remaining time indicates the LCG i The minimum remaining time of the RDB corresponding to all target objects determined by the Threk algorithm above is the minimum value of the LCG above. i The corresponding cache size indicates the LCG. i The sum of the data volume of all target objects determined by Threk as described above; if the Threk... k As a threshold corresponding to the packet delay state, the above LCG i The corresponding remaining time indicates the LCG i The minimum remaining time of the PDB corresponding to all third objects determined by the Threk above, the aforementioned LCG i The corresponding cache size indicates the LCG. i The sum of the data volume of all third objects determined based on the above Threk.

[0154] In an optional embodiment, the delay states can be arranged in order of thresholds, that is, delay states triggered by the same threshold are grouped together. For example, as shown in Figure 4e, if thre1 and thre2 are 1, and for thre1, LCH1 and LCH5 are both 1; for thre2, LCH2 and LCH6 are both 1; then first arrange the delay states of the two LCHs corresponding to thre1, with each LCH1 and LCH5 corresponding to 2 bytes to indicate its remaining time and buffer size; then arrange the delay states of the two LCHs corresponding to thre2, with each LCH2 and LCH6 corresponding to 2 bytes to indicate its remaining time and buffer size, and so on.

[0155] In another optional embodiment, the delay states can be sorted according to the LCH order, that is, the delay states of the same LCH are arranged together. For example, as shown in Figure 4f, if LCG3 and LCG6 are 1, and for LCG3, there are thre1 and thre2 both 1; for LCG6, there are thre2 and thre4 both 1; then first arrange the two threshold-triggered delay states corresponding to LCG3. For the delay states triggered by thre1 and thre2, each corresponds to 2 bytes to indicate its remaining time and buffer size; then arrange the two threshold-triggered delay states corresponding to LCG6. For the delay states triggered by thre2 and thre4, each corresponds to 2 bytes to indicate its remaining time and buffer size, and so on.

[0156] In this embodiment, the MAC CE of the fourth format can report the relative delay status or data packet delay status triggered by different thresholds, so that the network side can obtain the delay status triggered by different thresholds, which is convenient for the network side to perform scheduling.

[0157] Optionally, the status report reported by the terminal includes:

[0158] If the third condition is not met, the terminal reports a status report;

[0159] The third condition includes at least one of the following:

[0160] Before the first object and the second object meet the first condition, the target object has already triggered a status report.

[0161] The target object has been transmitted;

[0162] The target object is the one that transmits more slowly between the first object and the second object.

[0163] In this embodiment, if the target object has already triggered a status report before the target object currently triggers a status report (for example, the target object triggered a status report before the target object currently triggers a status report because the second condition was met) or the target object has been transmitted, the status report can be cancelled to save system resources; otherwise, the status report can be reported.

[0164] Optionally, the method further includes:

[0165] If the third condition is met, the terminal cancels the status report reporting.

[0166] This embodiment cancels the status report reporting when the third condition mentioned above is met, which helps to save system resources.

[0167] Optionally, the method further includes:

[0168] The terminal receives configuration information from the network-side device;

[0169] The configuration information includes at least one of the following: RDB, first time threshold, and second time threshold.

[0170] For example, at least one of the RDB, the first time threshold, and the second time threshold mentioned above can be configured at the granularity of each packet, each packet group, each QoS flow, or each LCG.

[0171] Optionally, the relative delay between the first object and the second object is the time difference between the first object being submitted to the lower layer and the second object being submitted to the lower layer;

[0172] Alternatively, the relative delay between the first object and the second object is the time difference between receiving the confirmation information from the first object and receiving the confirmation information from the second object.

[0173] For example, the aforementioned lower layer can be a lower layer of the PDCP layer, such as the radio link control (RLC) layer or the media access control (MAC) layer.

[0174] The aforementioned receipt of the confirmation information for the first object can be understood as receiving confirmation information for the first object from the network side, which indicates that the network side has received the first object. The aforementioned time difference in receiving the confirmation information for the second object can be understood as receiving confirmation information for the second object from the network side, which indicates that the network side has received the second object.

[0175] Optionally, the RDB includes a first RDB and a second RDB, wherein the relative delay between the first object and the second object is greater than or equal to the RDB, including:

[0176] When the first object is transmitted before the second object, the relative delay between the first object and the second object is greater than or equal to the first RDB.

[0177] When the second object is transmitted before the first object, the relative delay between the first object and the second object is greater than or equal to the second RDB.

[0178] And / or,

[0179] The first time threshold includes a first sub-threshold and a second sub-threshold. The remaining time of the RDB between the first object and the second object is less than or equal to the first time threshold, including:

[0180] If the first object is transmitted before the second object, the remaining time of the RDB between the first object and the second object is less than or equal to the first sub-threshold.

[0181] If the second object is transmitted before the first object, the remaining time of the RDB between the first object and the second object is less than or equal to the second sub-threshold.

[0182] And / or,

[0183] The second time threshold includes a third sub-threshold and a fourth sub-threshold. The relative time delay between the first object and the second object is greater than or equal to the second time threshold, including:

[0184] When the first object is transmitted before the second object, the relative delay between the first object and the second object is greater than or equal to the third sub-threshold.

[0185] When the second object is transmitted before the first object, the relative delay between the first object and the second object is greater than or equal to the fourth sub-threshold.

[0186] In this embodiment, the trigger thresholds corresponding to the first object being transmitted before the second object and the trigger thresholds corresponding to the second object being transmitted before the first object are different. This is beneficial for meeting the relative latency requirements in different scenarios.

[0187] Please refer to Figure 5, which is a flowchart of a transmission method provided in an embodiment of this application. This method can be executed by a network-side device, and as shown in Figure 5, it includes the following steps:

[0188] Step 501: The network-side device receives a status report from the terminal;

[0189] The status report includes at least one of a latency status report (DSR) and a data status report (BSR), wherein the DSR or BSR includes at least one of the following: a first remaining time and a first cache size;

[0190] The first remaining time is determined based on the remaining time of the relative latency budget RDB corresponding to the target object, and the first cache size is determined based on the amount of data of the target object;

[0191] The target object is the slower-transmitting object between the first object and the second object.

The first object or the second object includes data packets, data packet sets, or Quality of Service (QoS) flows.

[0192] Optionally, the first remaining time is the minimum value among the remaining times of the RDBs corresponding to all target objects within the first logical channel group (LCG).

[0193] And / or, the first cache size is the sum of the data amounts of all target objects within the first LCG;

[0194] Wherein, the first LCG can be any LCG.

[0198] The third object is a data packet that meets the second condition, which includes the following: the delay of the data packet is greater than or equal to the PDB, the remaining time of the PDB of the data packet is less than or equal to the third time threshold, and the delay of the data packet reaches the fourth time threshold.

[0199] Optionally, the first remaining time is the minimum of the remaining time of the RDB corresponding to all target objects in the first LCG and the remaining time of the PDB of all third objects in the first LCG.

[0200] And / or, the first cache size is the sum of the data volume of all target objects in the first LCG and the target data volume, wherein the target data volume is the data volume of a third object in the first LCG that is different from the target object;

[0206] Optionally, the second remaining time is the minimum value among the remaining times of the PDBs corresponding to all third objects within the first LCG;

[0207] And / or, the second cache size is the sum of the data amounts of all third objects within the first LCG;

[0208] Wherein, the first LCG can be any LCG.

[0235] It should be noted that the implementation method of this method can be found in the relevant description of the embodiment shown in Figure 3, and will not be repeated here.

[0236] The following examples illustrate this embodiment:

[0237] Referring to Figure 6, the transmission method provided in this embodiment includes the following steps:

[0238] Step 601: The UE or gNB obtains the MMSID and RDB associated with the QoS flow of the MM.

[0239] Step 602: The gNB configures a relative delay threshold (i.e., the second time threshold mentioned above) or a remaining time threshold of relative delay (i.e., the first time threshold mentioned above) for the UE.

[0240] Step 603: The UE counts the latency status of objects that exceed the configured threshold and triggers DSR.

[0241] In this step, the UE can count at least one of the first remaining time and the first cache size, and / or the UE can count at least one of the second remaining time and the second cache size. The first remaining time, the first cache size, the second remaining time and the second cache size can be referred to the relevant descriptions in the foregoing embodiments, and will not be repeated here.

[0242] Step 604: The UE reports DSR via MAC CE.

[0243] In this embodiment, the format of MAC CE can be found in the relevant descriptions of the foregoing embodiments, and will not be repeated here.

[0244] In summary, in this embodiment, the UE can utilize the DSR mechanism of related technologies to report relative latency (i.e., relative latency of different QoS flows in the MM service) triggered reports. This not only saves air interface overhead but also simplifies the parts of the standard that need modification, requiring only the definition of relative latency-related triggers. Alternatively, the UE can report the relative latency status and packet latency status of different QoS flows in the MM service based on the newly defined DSR report. In this case, if an object's PDB and RDB expire simultaneously, the relative latency status and packet latency status can be reported separately. Alternatively, it can be reported only in the PDB or RDB, with the other reporting only the difference. This facilitates the network side in distinguishing between packet latency status triggered by PDB and relative latency status triggered by RDB. When the UE is configured to simultaneously configure PDB (data latency) triggered DSR and RDB (relative latency) triggered DSR, the UE needs to determine whether the corresponding packet has already been reported with DSR to avoid the network side allocating unnecessary uplink resources. In addition, by defining the way MAC CE is filled, it can be ensured that the two DSRs will not send the same information repeatedly, which can avoid the network side allocating unnecessary uplink resources.
