[0053] D1, D1 represents the average delay of uplink PDCP data packets.

[0054] D2.1, D2.1 represents the average delay of air interface data packets.

[0058] 1)D1

[0059] D1 is measured at the PDCP layer of the terminal device. D1 is used to characterize the PDCP queuing delay belonging to a data radio bearer (DRB). Specifically, D1 refers to the time difference from when a data packet arrives at the PDCP upper service access point (PDCP upper SAP) to when the uplink authorization for transmitting the data packet becomes available. D1 can be defined by the following formula:

[0060]

[0061] Wherein, M(T, drbid) represents D1. The following Table 1 describes the various parameters in the above formula.

[0062]

[0063] Table 1

[0064] Reference Figure 2-1 , after the data packet reaches the PDCP layer of the terminal device (i.e., the PDCP upper layer service access point), the terminal device sends a scheduling request (Scheduling Request, SR) to the network device; the network device sends an uplink authorization of the media access control element (MAC Control Element, MAC CE) that can carry the buffer status report (Buffer Status Report, BSR) to the terminal device; the terminal device sends a BSR MACCE to the network device through the uplink authorization; the network device schedules the uplink authorization that can carry the data packet for the terminal device based on the BSR MAC CE; the terminal device uses the uplink authorization to send the data packet. D1 refers to the time difference from the arrival of the data packet at the PDCP layer to the time when the uplink authorization for transmitting the data packet becomes available. Here, the network device can be a base station, such as a gNB.

[0065] Reference Figure 2-2 , after the data packet reaches the PDCP layer of the terminal device (i.e., the PDCP upper layer service access point), the terminal device has an uplink authorization that can carry the BSR MAC CE, so it can directly use the uplink authorization to send the BSRMAC CE to the network device; the network device schedules the uplink authorization that can carry the data packet for the terminal device based on the BSR MAC CE; the terminal device uses the uplink authorization to send the data packet. D1 refers to the time difference from when the data packet arrives at the PDCP layer to when the uplink authorization for transmitting the data packet becomes available. Here, the network device can be a base station, such as a gNB.

[0066] 2) D2.1

[0067] D2.1 is measured at the MAC layer of the network device. Here, the network device can be a base station, such as a gNB. D2.1 is used to characterize the average delay of transmitting data packets on the air interface. Specifically, D2.1 refers to the time from the transmission time of the data packet given in the scheduling grant to the time when the receiving end (i.e., the network device) successfully receives the data packet. D2.1 can be defined by the following formula:

[0068]

[0069] Wherein, M(T, drbid) represents D2.1. Table 2 below explains the various parameters in the above formula.

[0070]

[0071] Table 2

[0072] Reference Figure 2-3 After the network device sends an uplink grant that can carry a data packet to the terminal device, the terminal device transmits the data packet according to the time corresponding to the uplink grant; the network device fails to receive the transmission block containing the data packet and sends a negative acknowledgement (NACK) to the terminal device; the terminal device retransmits the transmission block containing the data packet; the network device successfully receives the retransmitted transmission block containing the data packet and sends a positive acknowledgement (ACK) to the terminal device. D2.1 refers to the time from the transmission time of the data packet given in the scheduling grant to the time when the receiving end (i.e., the network device) successfully receives the data packet. Here, the network device can be a base station, such as a gNB.

[0073] 3)D2.2

[0074] D2.2 is measured at the RLC layer of the network device, where the network device can be a base station, such as a gNB. D2.2 refers to the time difference between the time when the RLC PDU containing the first part of the RLC SDU is received and the time when the RLC SDU is sent to the PDCP layer. D2.2 can be defined by the following formula:

[0075]

[0076] Wherein, M(T, drbid) represents D2.2. The following Table 3 describes the various parameters in the above formula.

[0077]

[0078] Table 3

[0079] Reference Figure 2-4, RLC PDU 1 containing the first part of RLC SDU i corresponds to TB1, RLC PDU 2 containing the second part of RLC SDU i corresponds to TB2, and RLC PDU 3 containing the third part of RLC SDU i corresponds to TB3. The RLC layer receives TB1 (i.e., RLC PDU 1), TB2 (i.e., RLC PDU 2), and TB3 (i.e., RLC PDU 3) sent by the MAC layer, among which TB3 is successfully received by the RLC layer after retransmission by the MAC layer. At this point, the MAC layer assembles RLC PDU 1, RLC PDU 2, and RLC PDU 3 into the corresponding RLC SDU i, and delivers RLC SDU i to the PDCP layer. D2.2 refers to the time difference between the time when the RLC PDU containing the first part of the RLC SDU is received and the time when the RLC SDU is sent to the PDCP layer.

[0080] 4)D2.4

[0081] D2.4 is measured at the PDCP layer of the network device. Here, the network device can be a base station, such as a gNB. D2.4 is used to characterize the average delay of the network device for PDCP reordering of received data packets. Specifically, D2.4 refers to the delay from the time a PDCP PDU is received to the time the PDCP PDU is sent to the upper layer service access point. D2.4 can be defined by the following formula:

[0082]

[0083] Wherein, M(T, drbid) represents D2.4. Table 4 below explains the various parameters in the above formula.

[0084]

[0085] Table 4

[0086] ●Cross-base station bearer under dual-connection architecture

[0087] Reference Figure 3-1 , Figure 3-1 It is a schematic diagram of the protocol stack of the MN terminated SCG bearer. For the MN terminated SCG bearer, the PDCP layer of the bearer is located on the MN side, and the RLC layer and MAC layer of the bearer are located on the SN side.

[0088] Reference Figure 3-2 , Figure 3-2It is a schematic diagram of a protocol stack of a MN terminated split bearer. For a MN terminated split bearer, the PDCP layer of the bearer is located at the MN side, and the RLC layer and MAC layer of the bearer are located at the MN side and the SN side.

[0089] Above Figure 3-1 and Figure 3-2 The termination points of the bearers shown are all at the PDCP layer of the MN, and the uplink / downlink data packets on the SN side need to be transmitted through the Xn interface between the MN and the SN.

[0090] Reference Figure 3-3 , Figure 3-3 It is a schematic diagram of the protocol stack of the SN terminated MCG bearer. For the SN terminated MCG bearer, the PDCP layer of the bearer is located on the SN side, and the RLC layer and MAC layer of the bearer are located on the MN side.

[0091] Reference Figure 3-4 , Figure 3-4 It is a schematic diagram of a protocol stack of an SN terminated split bearer. For an SN terminated split bearer, the PDCP layer of the bearer is located at the SN side, and the RLC layer and MAC layer of the bearer are located at the SN side and the MN side.

[0092] Above Figure 3-3 and Figure 3-4 The termination points of the bearers shown are all at the PDCP layer of the SN, and the uplink / downlink data packets on the MN side need to be transmitted through the Xn interface between the MN and the SN.

[0093] Each component (D1, D2.1, D2.2, D2.4) of the uplink transmission delay is related to the protocol layer. In the dual-connection architecture, the protocol layer used by the bearer has the above-mentioned different situations. How to support the measurement of the uplink transmission delay in the dual-connection scenario needs to be solved. To this end, the following technical solution of the embodiment of the present application is proposed.

[0094] It should be noted that the technical solution of the embodiment of the present application can be applied to a dual-connection architecture, and the types of dual-connection architectures include but are not limited to: MR-DC, NR-DC, EN-DC, NE-DC, etc.

[0095] It should be noted that the first delay in the present application corresponds to D1 in the above solution, the second delay corresponds to D2.1 in the above solution, the third delay corresponds to D2.2 in the above solution, and the fourth delay corresponds to D2.4 in the above solution.

[0096] Figure 4The following is a flow chart of the transmission delay measurement method provided in the embodiment of the present application. Figure 1 ,like Figure 4 As shown, the transmission delay measurement method includes the following steps:

[0097] Step 401: The terminal device sends a measurement report to the network device, and the measurement report includes a first delay measurement value, where the first delay refers to the average delay of an uplink packet data convergence protocol PDCP data packet; wherein the measurement report also carries first indication information, and the first indication information is used to indicate whether the transmission delay corresponding to the first delay measurement value is a transmission delay towards the main node MN or a transmission delay towards the secondary node SN.

[0098] In the embodiment of the present application, the network device may be a MN or a SN.

[0099] In the embodiment of the present application, when the transmission mode of split bearer is adopted, refer to Figure 3-2 and Figure 3-4 , the bearer has two paths, one path corresponds to the RLC layer and MAC layer of MN, and the other path corresponds to the RLC layer and MAC layer of SN. For uplink transmission, the terminal device can send data to MN and SN at the same time through the split bearer. The uplink scheduling speeds of MN and SN for the terminal device may be different, and the first delay (i.e., D1) is related to the uplink scheduling (i.e., uplink authorization). Therefore, if the first delay measured by the PDCP layer of the terminal device is for MN transmission, the measured value of the first delay needs to be determined based on the uplink authorization of MN; if the first delay measured by the PDCP layer of the terminal device is for SN transmission, the measured value of the first delay needs to be determined based on the uplink authorization of SN. Here, the measured value of the first delay can be understood with reference to the aforementioned description of D1.

[0100] In order to make the network side clear about the difference in PDCP queuing delays of data packets transmitted by the terminal device to the MN and SN through the air interface, the terminal device informs the network side whether the transmission delay corresponding to the measurement result (i.e., the first delay measurement value) is the transmission delay for the primary node MN or the transmission delay for the secondary node SN each time it reports a measurement report. Specifically, in addition to the first delay measurement value, the measurement report also includes first indication information, and the first indication information is used to indicate whether the transmission delay corresponding to the first delay measurement value is the transmission delay for the MN or the transmission delay for the SN.

[0101] In an optional manner, the measurement report includes a first delay measurement value, and the first indication information is used to indicate that the transmission delay corresponding to the first delay measurement value is a transmission delay oriented to the MN.

[0102] Reference Figure 5In case 1, the measurement report includes a value of 1 for D1, and indicates that the transmission delay corresponding to the value 1 is the transmission delay toward the MN.

[0103] In an optional manner, the measurement report includes a first delay measurement value, and the first indication information is used to indicate that the transmission delay corresponding to the first delay measurement value is a SN-oriented transmission delay.

[0104] Reference Figure 5 In case 2, the measurement report includes a value 2 of D1, and indicates that the transmission delay corresponding to the value 2 is the transmission delay toward the SN.

[0105] In an optional manner, the measurement report includes two first delay measurement values, and the first indication information is used to indicate that the transmission delay of one of the two first delay measurement values ​​is the transmission delay towards the MN, and the transmission delay of the other first delay measurement value is the transmission delay towards the SN.

[0106] Reference Figure 5 In case three, the measurement report includes a value 1 of D1 and a value 2 of D1, and indicates that the transmission delay corresponding to the value 1 is the transmission delay toward the MN, and the transmission delay corresponding to the value 2 is the transmission delay toward the SN.

[0107] Figure 6 FIG. 2 is a flow chart of a method for measuring transmission delay provided in an embodiment of the present application. Figure 6 As shown, the transmission delay measurement method includes the following steps:

[0108] Step 601: The network device determines the uplink transmission delay based on a first delay measurement value within a first time period, a second delay measurement value within the first time period, a third delay measurement value within the first time period, and a fourth delay measurement value within the first time period; wherein the first delay refers to the average delay of uplink PDCP data packets, the second delay refers to the average delay of air interface data packets, the third delay refers to the average delay of radio link control RLC data packets, and the fourth delay refers to the average PDCP reordering delay.

[0109] In the embodiment of the present application, the network device is MN or SN.

[0110] In an embodiment of the present application, the network device determines the sum of a first delay measurement value in a first time period, a second delay measurement value in the first time period, a third delay measurement value in the first time period, and a fourth delay measurement value in the first time period as the uplink transmission delay.

[0111] Taking the first time period as T1 as an example, the uplink transmission delay can be calculated by the following formula:

[0112] D_T1=D1_T1+D2.1_T1+D2.2_T1+D2.4_T1

[0113] Among them, D_T1 represents the uplink transmission delay, D1_T1 represents the first delay measurement value in the first time period, D2.1_T1 represents the second delay measurement value in the first time period, D2.2_T1 represents the third delay measurement value in the first time period, and D2.4_T1 represents the fourth delay measurement value in the first time period.

[0114] The network device adds the first delay measurement value, the second delay measurement value, the third delay measurement value and the fourth delay measurement value belonging to the same time period (ie, the first time period) using the above formula to obtain the final uplink transmission delay corresponding to the time period.

[0115] In the embodiment of the present application, the first delay measurement value is obtained by measuring the terminal device. Specifically, the first delay measurement value (ie, D1) is obtained by measuring the PDCP layer of the terminal device.

[0116] In the embodiment of the present application, the measurement positions of the second delay measurement value, the third delay measurement value and the fourth delay measurement value may be implemented in the following ways.

[0117] A) Method 1

[0118] The second delay measurement value and the third delay measurement value are obtained by SN measurement, and the fourth delay measurement value is obtained by MN measurement.

[0119] In one example, for a MN-terminated SCG bearer (see Figure 3-1 ), D2.1 and D2.2 are measured by the SN, wherein D2.1 is measured by the MAC layer of the SN, and D2.2 is measured by the RLC layer of the SN; D2.4 is measured by the MN, specifically, D2.4 is measured by the PDCP layer of the MN.

[0120] In one example, for a MN-terminated offload bearer (see Figure 3-2 ), for the second path of the bearer, D2.1 and D2.2 are measured by the SN, where D2.1 is measured by the MAC layer of the SN, and D2.2 is measured by the RLC layer of the SN; D2.4 is measured by the MN, specifically, D2.4 is measured by the PDCP layer of the MN. It should be noted that in this case, D1 measured by the PDCP layer of the terminal device needs to correspond to SN-oriented transmission.

[0121] In an optional method, if the measurement aggregation point is MN (that is, the network device is MN), MN needs to receive the second delay measurement value and the third delay measurement value reported by SN, as well as the first delay measurement value reported by the receiving terminal device, and then calculate the final uplink transmission delay in combination with the fourth delay measurement value obtained by its own measurement.

[0122] In another optional method, if the measurement aggregation point is SN (that is, the network device is SN), SN needs to receive the fourth delay measurement value reported by MN and the first delay measurement value reported by the receiving terminal device, and then calculate the final uplink transmission delay based on the second delay measurement value and the third delay measurement value obtained by its own measurement.

[0123] B) Method 2

[0124] The second delay measurement value and the third delay measurement value are obtained by SN measurement, and the fourth delay measurement value is obtained by SN measurement.

[0125] In one example, for a SN terminated offload bearer (see Figure 3-4 ), for the first path of the bearer, D2.1 and D2.2 are measured by the SN, wherein D2.1 is measured by the MAC layer of the SN, and D2.2 is measured by the RLC layer of the SN; D2.4 is measured by the SN, specifically, D2.4 is measured by the PDCP layer of the SN. It should be noted that in this case, D1 measured by the PDCP layer of the terminal device needs to correspond to SN-oriented transmission.

[0126] In an optional method, if the measurement aggregation point is MN (that is, the network device is MN), MN needs to receive the second delay measurement value, the third delay measurement value and the fourth delay measurement value reported by SN, and the first delay measurement value reported by the receiving terminal device, and then calculate the final uplink transmission delay.

[0127] In another optional method, if the measurement aggregation point is SN (that is, the network device is SN), SN needs to receive the first delay measurement value reported by the terminal device, and then calculate the final uplink transmission delay based on the second delay measurement value, the third delay measurement value and the fourth delay measurement value obtained by its own measurement.

[0128] C) Method 3

[0129] The second delay measurement value and the third delay measurement value are obtained by measuring by the MN, and the fourth delay measurement value is obtained by measuring by the SN.

[0130] In one example, for an SN terminated MCG bearer (see Figure 3-3), D2.1 and D2.2 are measured by the MN, wherein D2.1 is measured by the MAC layer of the MN, and D2.2 is measured by the RLC layer of the MN; D2.4 is measured by the SN, specifically, D2.4 is measured by the PDCP layer of the SN.

[0131] In one example, for a SN terminated offload bearer (see Figure 3-4 ), for the second path of the bearer, D2.1 and D2.2 are measured by the MN, wherein D2.1 is measured by the MAC layer of the MN, and D2.2 is measured by the RLC layer of the MN; D2.4 is measured by the SN, specifically, D2.4 is measured by the PDCP layer of the SN. It should be noted that in this case, D1 measured by the PDCP layer of the terminal device needs to correspond to the transmission towards the MN.

[0132] In an optional method, if the measurement aggregation point is MN (that is, the network device is MN), MN needs to receive the fourth delay measurement value reported by SN and the first delay measurement value reported by the receiving terminal device, and then calculate the final uplink transmission delay based on the second delay measurement value and the third delay measurement value obtained by its own measurement.

[0133] In another optional method, if the measurement aggregation point is SN (that is, the network device is SN), SN needs to receive the second delay measurement value and the third delay measurement value reported by MN, and the first delay measurement value reported by the receiving terminal device, and then calculate the final uplink transmission delay in combination with the fourth delay measurement value obtained by its own measurement.

[0134] D) Method 4

[0135] The second delay measurement value and the third delay measurement value are obtained by measuring by the MN, and the fourth delay measurement value is obtained by measuring by the MN.

[0136] In one example, for a MN-terminated offload bearer (see Figure 3-2 ), for the first path of the bearer, D2.1 and D2.2 are measured by the MN, wherein D2.1 is measured by the MAC layer of the MN, and D2.2 is measured by the RLC layer of the MN; D2.4 is measured by the MN, specifically, D2.4 is measured by the PDCP layer of the MN. It should be noted that in this case, D1 measured by the PDCP layer of the terminal device needs to correspond to the transmission towards the MN.

[0137] In an optional method, if the measurement aggregation point is MN (that is, the network device is MN), MN needs to receive the first delay measurement value reported by the terminal device, and then calculate the final uplink transmission delay based on the second delay measurement value, the third delay measurement value and the fourth delay measurement value obtained by its own measurement.

[0138] In another optional method, if the measurement aggregation point is SN (that is, the network device is SN), SN needs to receive the second delay measurement value, the third delay measurement value and the fourth delay measurement value reported by MN, and the first delay measurement value reported by the terminal device, and then calculate the final uplink transmission delay.

[0139] In an embodiment of the present application, when the measurement aggregation point is MN or SN, in order to enable the network device to add the first delay measurement value, the second delay measurement value, the third delay measurement value and the fourth delay measurement value obtained in the same time period (i.e., the first time period), it is stipulated that relevant information of the first time period needs to be added to the measurement report reported to the measurement aggregation point.

[0140] Specifically, the measurement report where the first delay measurement value is located, the measurement report where the second delay measurement value is located, the measurement report where the third delay measurement value is located, and the measurement report where the fourth delay measurement value is located carry second indication information, and the second indication information is used to determine the first time period.

[0141] In an optional manner, the second indication information is used to indicate the Nth time period, where N is a positive integer, and the value of N is determined based on the start time of this measurement, the configured start time of measurement, and the configured measurement interval period.

[0142] In an optional manner, the second indication information is used to indicate a time difference between the start time of this measurement and the configured start time of measurement.

[0143] In an optional manner, the second indication information is used to indicate the start time of this measurement.

[0144] In specific implementation, the core network element and / or the access network element (such as a base station) configures the measurement interval period and the measurement start time in the MDT measurement configuration signaling, wherein the measurement interval period is used to determine the period of the delay measurement, and the measurement start time is used to determine the time starting point of the measurement start. The MN, SN and terminal equipment attach time-related labels in their respective corresponding measurement reports, such as the Nth time period, or the time difference between the current measurement start time and the configured measurement start time, or the current measurement start time.

[0145] For example, if the measurement interval configured in the MDT measurement configuration signaling is 5s and the measurement start time is 9:00:00, then the time tag in the measurement report sent by the SN to the MN for the measurement at 9:00:30 can be T6 (i.e., the 6th time period), or 30s, or 9:00:30. Similarly, the measurement report of the terminal device will also be sent to the MN in this form. Finally, the MN summarizes the various delays and generates the upload transmission delay corresponding to 9:00:30.
