[0002] In the NR (New Radio) system, the base station generally allocates uplink resources to the terminal periodically. In order to send uplink data, the terminal needs to first send an SR (Scheduling Request) on the PUCCH (Physical Uplink Control Channel). After receiving the SR, the base station sends an uplink authorization. The terminal sends a BSR (Buffer Status Report) according to the uplink authorization to further request uplink resources, and sends uplink data after obtaining the uplink scheduling.

[0036] The term "plurality" in the embodiments of the present disclosure refers to two or more than two, and other quantifiers are similar thereto.

Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0038] The disclosed embodiments provide an uplink pre-scheduling processing method, apparatus, network equipment and storage medium, which are used to determine the pre-scheduling notification information submitted by the high-level layer when the current reporting period expires based on the packet period of the uplink data and the pre-scheduling data packet size learned by the high-level layer. According to the pre-scheduling notification information submitted by the high-level layer, each DRB pre-scheduling time point is determined, and uplink pre-scheduling processing is performed based on the pre-scheduling time point and the pre-scheduling data packet size of each DRB pre-scheduling time point, which can realize sparse uplink pre-scheduling processing, improve the prediction hit rate of the pre-scheduling period, reduce the empty packet rate and IOT (Interference over Thermal, uplink interference), improve the uplink spectrum efficiency, and meet the application delay requirements.

[0039] Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0040] The technical solution provided by the embodiment of the present disclosure can be applicable to a variety of systems, especially 5G systems. For example, the applicable system can be a global system of mobile communication (GSM) system, a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) general packet radio service (GPRS) system, a long term evolution (LTE) system, a LTE frequency division duplex (FDD) system, a LTE time division duplex (TDD) system, an advanced long term evolution (LTE-A) system, a universal mobile telecommunication system (UMTS), a world-wide interoperability for microwave access (WiMAX) system, a 5G new radio (NR) system, etc. These various systems include terminal equipment and network equipment.

In some network structures, the network device may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be arranged geographically separately.

[0042] Figure 1 It is a flow chart of an uplink pre-scheduling processing method provided according to an embodiment of the present disclosure. It should be noted that the uplink pre-scheduling processing method provided by the embodiment of the present disclosure can be applied to the uplink pre-scheduling processing device provided by the embodiment of the present disclosure. Exemplarily, the processing device can be configured on a network device.

[0043] like Figure 1 As shown, the uplink pre-scheduling processing method includes but is not limited to the following steps:

[0044] In step S101, a pre-scheduling notification message submitted by a higher layer of a network device when a current reporting period expires is obtained.

[0045] In an embodiment of the present disclosure, the pre-scheduled notification message includes the pre-scheduled data volume of each data radio bearer (DRB) in at least one DRB, wherein the pre-scheduled data volume may include the packet period and pre-scheduled data packet size of the uplink data learned by the higher layer based on the corresponding DRB in the current reporting period.

[0046] In some embodiments, the network device includes a high layer and a MAC (Media Access Control) layer. In one implementation, the MAC layer of the network device obtains a pre-scheduling notification message submitted by the high layer of the network device when the current reporting period expires. That is, the high layer can periodically report a pre-scheduling notification message to the MAC layer, and the pre-scheduling notification message includes a packet period and a pre-scheduling data packet size of uplink data learned by the high layer based on the corresponding DRB in the current reporting period.

[0047] In some embodiments of the present disclosure, within the current reporting period, the high layer parses the uplink data packets received by at least one DRB, counts the packet period and pre-scheduled data packet size of the uplink data received by the corresponding DRB, and sends the statistical results to the MAC layer in the form of a pre-scheduled notification message, so that the MAC layer can obtain the pre-scheduled notification message submitted by the high layer when the current reporting period expires.

[0048] In step S102, the pre-scheduling time point of each DRB is generated according to the packet period of the uplink data in the pre-scheduled data volume of each DRB and the Scheduling Request (SR) period.

[0049] In some embodiments of the present disclosure, the SR cycle is determined, and the number of pre-scheduling times is determined, and the pre-scheduling interval is determined based on the SR cycle and the number of pre-scheduling times. For each DRB, the initial air interface transmission time of the last data packet of the DRB in the current reporting cycle is determined based on the packet period associated with the DRB, and the pre-scheduling time point of the DRB is generated based on the length of the initial air interface transmission time from the next SR time point, and the pre-scheduling interval. Since the pre-scheduling interval is determined based on the number of pre-scheduling times and the SR cycle, and each pre-scheduling time point is determined based on the packet period obtained by high-level self-learning and the next SR time point, the generated DRB pre-scheduling time point is sparse, so that sparse pre-scheduling can be achieved.

[0050] In step S103, uplink pre-scheduling processing is performed based on the pre-scheduling time point of each DRB and the pre-scheduled data packet size in the pre-scheduled data volume of each DRB.

[0051] In some embodiments of the present disclosure, for each DRB, a pre-scheduling linked list of the DRB is constructed to store the pre-scheduling time point of the DRB and the pre-scheduling data packet size in the pre-scheduling data volume of the DRB. According to the pre-scheduling linked list of each DRB, it is determined whether the current moment is a pre-scheduling time point. When the current moment is a pre-scheduling time point, corresponding pre-scheduling processing is performed according to the information in the pre-scheduling linked list.

[0052] In some embodiments of the present disclosure, when the number of DRBs is one, at the pre-scheduling time point, uplink pre-scheduling processing is performed according to the pre-scheduling data packet size of the DRB.

[0053] In some embodiments of the present disclosure, when there are multiple DRBs, the pre-scheduled data packet sizes of different DRBs pre-scheduled at the same pre-scheduled time point are merged; at the pre-scheduled time point, uplink pre-scheduling is performed according to the pre-scheduled data packet sizes after the merge. In other words, BO (Buffer Occupy) merging is performed on different DRBs at the same pre-scheduled time point.

[0054] In the embodiment of the present disclosure, based on the packet period of uplink data and the pre-scheduled data packet size learned by the high-level layer, the pre-scheduled notification information submitted by the high-level layer when the current reporting period expires is determined. According to the pre-scheduled notification information submitted by the high-level layer, each DRB pre-scheduled time point is determined, and uplink pre-scheduled processing is performed based on each DRB pre-scheduled time point and the pre-scheduled data packet size, thereby realizing sparse uplink pre-scheduled processing, improving the prediction hit rate of the pre-scheduled period, reducing the empty packet rate and IOT (Interference over Thermal, uplink interference), improving the uplink spectrum efficiency, and meeting the application delay requirements.

[0055] It should be noted that for each DRB, the upper layer is used as the execution body, and the uplink data received by the DRB is self-learned within the current reporting period to obtain the packet period and pre-scheduled data packet size of the uplink data, and the packet period and pre-scheduled data packet size information of the uplink data are added to the pre-scheduled data volume of the DRB. When the number of DRBs is one, the upper layer adds the pre-scheduled data volume of the DRB to the pre-scheduled notification information. When the number of DRBs is multiple, the upper layer adds the pre-scheduled data volume of multiple DRBs to the pre-scheduled notification information. When the current reporting period expires, the pre-scheduled notification information is submitted to the MAC layer. After the pre-scheduled notification information is submitted by the upper layer, the MAC layer is used as the execution body to perform operations such as generating a pre-scheduled time point and uplink pre-scheduling processing according to the received pre-scheduled notification information. Optionally, Figure 2FIG. 1 is a flowchart of a high-level self-learning of uplink data received by each DRB according to an embodiment of the present disclosure. Figure 2 As shown, the process of the high layer performing self-learning on the uplink data received by each DRB includes but is not limited to the following steps:

[0056] In step S201, the number of uplink data packets and the maximum packet size received by the corresponding DRB in the current reporting period are counted.

[0057] In some embodiments of the present disclosure, after determining that the pre-scheduling function control switch is turned on, the number of uplink data packets and the maximum packet size received by the corresponding DRB in the current reporting period are counted.

[0058] Optionally, the pre-scheduling function control switch is used to control the on and off of the pre-scheduling function of the network device, which can be configured by the network, wherein the configured parameters can be represented by SlaSwitch. Exemplarily, the network is configured with the SlaSwitch, and its value can be 0 or 1, or it can be on or off. For example, when the value of SlaSwitch is 1, the pre-scheduling function of the network device is on, and the upper layer can self-learn the uplink data received by each DRB; when the value of SlaSwitch is 0, the pre-scheduling function of the network device is off, and the network device does not perform pre-scheduling processing.

[0059] In step S202, it is determined whether the number of packets reaches a first threshold, and the period of each uplink data packet is calculated.

[0060] In some embodiments of the present disclosure, within a reporting period, a higher layer may periodically perform statistics on the period of uplink data packets, and each statistics may be referred to as a statistical period. That is, a reporting period may include multiple statistical periods.

[0061] Optionally, the end condition of a statistical period may be that the number of uplink data packets received by the DRB within the statistical period reaches a first threshold.

[0062] Optionally, the first threshold refers to the limit on the number of uplink data packets received by the DRB in a statistical period, which can be configured by the network, wherein the configured parameters can be represented by SlaNPkg. Exemplarily, the network configures the SlaNPkg, and its value range can be [1,100]. For example, the value of the first threshold configured by the network is 100. When the number of uplink data packets received by the DRB in a statistical period does not reach 100, the uplink data packets continue to be parsed; when the number of uplink data packets received by the DRB in a statistical period reaches 100, the period of each uplink data packet in the statistical period is calculated, and the statistical period ends. If the current reporting period has not ended, enter the next statistical period and recount the uplink data packets received by the DRB.

[0063] In step S203, an average value is calculated according to the period of each uplink data packet, and the obtained average value is determined as the packet period of the uplink data learned based on the corresponding DRB in the current reporting period.

[0064] In some embodiments of the present disclosure, when the current reporting period includes a statistical period, the average value is calculated based on the period of each uplink data packet in the statistical period, and the obtained average value is determined as the packet period of the uplink data learned based on the corresponding DRB in the current reporting period.

[0065] As an example, the value of the first threshold is 2. In the current reporting period, the DRB receives two uplink data packets in sequence, namely uplink data packet A and uplink data packet B, and the period of both data packets is 2 slots (time slots). Since the value of the first threshold is 2, the current reporting period includes a statistical period, and the uplink data in the statistical period includes uplink data packet A and uplink data packet B. Based on the average period of uplink data packet A and uplink data packet B, the packet period of the statistical period is 2 slots. Therefore, the packet period of the uplink data learned based on the corresponding DRB in the current reporting period is 2 slots.

[0066] In some embodiments of the present disclosure, when the current reporting period includes multiple statistical periods, for each statistical period, the period of each uplink data packet in the statistical period is averaged to obtain the packet period of the uplink data in the statistical period. For the current reporting period, the packet period of the uplink data in each statistical period in the current reporting period is averaged, and the obtained average value is determined as the packet period of the uplink data learned based on the corresponding DRB in the current reporting period.

[0067] As an example, the value of the first threshold is 2. In the current reporting period, the DRB receives four uplink data packets in sequence, namely uplink data packet 1, uplink data packet 2, uplink data packet 3 and uplink data packet 4, and the period of each of the four data packets is 4 slots. Since the value of the first threshold is 2, the current packet period includes two statistical periods, namely statistical period 1 and statistical period 2. The uplink data in statistical period 1 includes uplink data packet 1 and uplink data packet 2; the uplink data in statistical period 2 includes uplink data packet 3 and uplink data packet 4. According to the average value of the period of the uplink data packets in statistical period 1, the packet period of statistical period 1 is 2 slots. According to the average value of the period of the uplink data packets in statistical period 2, the packet period of statistical period 2 is 2 slots. According to the average value of the packet period of each statistical period in the current reporting period, the average value is 2 slots. Therefore, the packet period of the uplink data learned based on the corresponding DRB in the current reporting period is 2 slots.

[0068] In step S204, the pre-scheduled data packet size of the uplink data learned based on the corresponding DRB in the current reporting period is determined according to the packet period of the uplink data and the pre-scheduled default scheduling packet size or the maximum packet size.

[0069] In some embodiments of the present disclosure, the pre-scheduled data packet size of the uplink data learned based on the corresponding DRB in the current reporting period is determined according to the relationship between the packet period of the uplink data and the size of a preset number of slots.

[0070] Optionally, the above-mentioned preset number of slots may be 1 slot.

[0071] As a possible implementation method, when the packet period of uplink data is less than a preset number of slots, the pre-scheduled default scheduling packet size is adjusted according to the ratio of the packet period of uplink data to the preset number of time slots, and the adjusted packet size is determined as the pre-scheduled data packet size of the uplink data learned based on the corresponding DRB in the current reporting period.

[0072] For example, the preset number is 1, the packet period of uplink data is 0.5 slots, and the pre-scheduled data packet size of uplink data is 500 bytes. Since the packet period of uplink data is less than 1 slot, it is re-determined to 1 slot. The ratio of the packet period of uplink data to 1 slot is The pre-scheduled data packet size value of the uplink data is modified to 1000 bytes in the same proportion.

[0073] As a possible implementation method, when the packet period of uplink data is greater than or equal to a preset number of slots, the maximum packet size is determined as the pre-scheduled data packet size of the uplink data learned based on the corresponding DRB in the current reporting period.

[0074] For example, the preset number is 1, the packet period of the uplink data is 2 slots, and the maximum packet size of the uplink data is 1000 bytes. Since the packet period of the uplink data is greater than 1 slot, the pre-scheduled data packet size of the uplink data is determined to be 1000 bytes.

[0075] In an embodiment of the present disclosure, the upper layer self-learns the packet period and pre-scheduled data packet size of the uplink data based on the uplink data received by at least one DRB. Based on the packet period and pre-scheduled data packet size of the uplink data self-learned by the upper layer, the network device can implement periodic prediction of resource scheduling requirements for the uplink data.

[0076] It should be noted that the method for generating the pre-scheduling time point for each DRB is determined based on the relationship between the packet period of the uplink data and the SR period in the pre-scheduled data volume of each DRB. When the packet period of the uplink data is greater than or equal to the SR period, the pre-scheduling interval is determined based on the SR period and the number of pre-scheduling times. The pre-scheduling time point of the DRB is generated based on the initial air interface transmission time of the last packet of data of the DRB in the current reporting period and the pre-scheduling interval. When the packet period of the uplink data is less than or equal to the SR period and the sum of the current time and the packet period includes the next SR time point, the pre-scheduling time point of the DRB is generated according to the situation that the packet period of the uplink data is greater than or equal to the SR period; when the packet period of the uplink data is less than or equal to the SR period and the sum of the current time and the packet period does not include the next SR time point, the pre-scheduling time points of the DRB are generated at equal intervals. Optionally, Figure 3 FIG. 1 is a flowchart of another uplink pre-scheduling processing method provided according to an embodiment of the present disclosure. Figure 3 As shown, when the packet period of the uplink data is greater than or equal to the SR period, the uplink pre-scheduling processing method includes but is not limited to the following steps:

[0077] In step S301, a pre-scheduling notification message submitted by a higher layer of a network device when a current reporting period expires is obtained. The pre-scheduling notification message includes the pre-scheduled data volume of each DRB in at least one data radio bearer DRB. The pre-scheduled data volume includes the packet period and pre-scheduled data packet size of the uplink data learned by the higher layer based on the corresponding DRB during the current reporting period.

[0078] In the embodiments of the present disclosure, step S301 may be implemented in any manner in the embodiments of the present disclosure, and the embodiments of the present disclosure do not limit this and will not be described in detail.

[0079] In step S302, for the packet period of uplink data in the pre-scheduled data volume of each DRB, it is determined that the packet period is greater than or equal to the SR period.

[0080] In step S303, the initial air interface transmission time of the last packet of data of the DRB in the current reporting period is determined according to the packet period.

[0081] In some embodiments of the present disclosure, the initial air interface transmission time may be determined by time information included in the data packet, for example, a frame number or a time slot number.

[0082] In step S304, the pre-scheduling interval is determined according to the SR period and the number of pre-scheduling times.

[0083] In some embodiments of the present disclosure, the ratio of the SR cycle to the number of pre-scheduling times is calculated, and the pre-scheduling interval is determined according to the relationship between the ratio and 1. Exemplarily, when the ratio is greater than 1, the pre-scheduling interval is determined to be the ratio. When the ratio is less than or equal to 1, the pre-scheduling interval is determined to be 1.

[0084] Optionally, the SR period refers to the period during which the terminal requests resources for uplink data transmission, which may be configured by the network, wherein the configured parameters may be represented by SRPeriod, and exemplarily, the network configures the SRPeriod, and its value range is [11slot, 1640slot]. The number of pre-scheduling times is the number of pre-scheduling times within an SR period, which may be configured by the network, wherein the configured parameters may be represented by SlaScheNTime, and exemplarily, the network configures the SlaScheNTime, and its value range may be [1, 1000].

[0085] For example, after the SR period and the number of pre-scheduling times are configured, the pre-scheduling interval can be calculated using the following formula (1):

[0086]

[0087] Among them, ScheInterval refers to the pre-scheduling interval, SRPeriod refers to the SR period, and SlaScheNTime refers to the number of pre-scheduling times. As an example, when the SR period is 20 slots and the number of pre-scheduling times is 5, the ratio of the SR period to the number of pre-scheduling times is 4. This ratio is greater than 1, so the pre-scheduling interval is 4 slots. As another example, when the SR period is 2 slots and the number of pre-scheduling times is 5, the ratio of the SR period to the number of pre-scheduling times is 0.4. This ratio is less than 1, so the pre-scheduling interval is 1 slot.

[0088] In step S305, the distance between the initial air interface transmission time and the next SR time point is determined.

[0089] As an example, the length of the initial air interface time to the next SR time point refers to the time length from the initial air interface time to the next SR time point, and its unit is slot. For example, if the initial air interface time is 2 slots and the next SR time point is 8 slots, then the length of the initial air interface time to the next SR time point is 6 slots.

[0090] In step S306, the pre-scheduling time point of the DRB is generated according to the length of the initial air interface transmission time to the next SR time point and the pre-scheduling interval.

[0091] In some embodiments of the present disclosure, a remainder calculation is performed based on the length of the initial air interface time from the next SR time point and the pre-scheduling interval, and the obtained remainder is determined as the time length from the initial air interface time to the first pre-scheduling time point (or called time offset). Subsequent pre-scheduling time points are separated by a time length of the pre-scheduling interval, or in other words, the offset of the subsequent pre-scheduling time point from the previous pre-scheduling time point is the pre-scheduling interval. For example, after determining the length of the initial air interface time from the next SR time point and the pre-scheduling interval, the following formula (2) can be used to calculate the time length from the initial air interface time to the first pre-scheduling time point (or called time offset):

[0092] P0 = Distance % ScheInterval (2)

[0093] Among them, P0 refers to the time length from the initial air interface transmission time to the first pre-scheduling time point (or called time offset); Distance refers to the length from the initial air interface transmission time to the next SR time point; ScheInterval refers to the pre-scheduling interval.

[0094] For example, Figure 4 is a schematic diagram of an uplink pre-scheduling processing method provided according to an embodiment of the present disclosure, such as Figure 4 As shown, when the first SR time point is the 1st slot, the second SR time point is the 7th slot, the initial transmission air interface time is the 2nd slot, and the pre-scheduling interval is 2 slots, the length of the initial transmission air interface time from the second SR time point is determined to be 5 slots. According to the length of the initial transmission air interface time from the second SR time point and the pre-scheduling interval, the time length from the initial transmission air interface time to the first pre-scheduling time point can be obtained as 1 slot. Therefore, according to the length of the initial transmission air interface time from the next SR time point and the pre-scheduling interval, the generated DRB pre-scheduling time point includes the first pre-scheduling time point, the second pre-scheduling time point and the third pre-scheduling time point. Among them, the first pre-scheduling time point is the 3rd slot, the second pre-scheduling time point is the 5th slot, and the third pre-scheduling time point is the 7th slot.

The pre-scheduling time point of DRB is generated according to the initial air interface transmission time of the last packet of data of DRB in the current reporting period and the pre-scheduling interval, so that the pre-scheduling time point is the same as the SR time point, so as to reduce the time consumption of executing SR scheduling, improve the hit rate of pre-scheduling, and reduce service delay.

[0098] It should be noted that when the packet period of uplink data is less than or equal to the SR period and the sum of the current time and the packet period contains the next SR time point, the pre-scheduled time point of DRB is generated according to the situation that the packet period of uplink data is greater than or equal to the SR period.

[0114] In an embodiment of the present disclosure, when the packet period of uplink data is less than or equal to the SR period and the sum of the current time and the packet period contains the next SR time point, the pre-scheduling time point of the DRB is generated according to the situation that the packet period of the uplink data is greater than or equal to the SR period, so that the pre-scheduling time point is the same as the SR time point, so as to reduce the time consumption of executing SR scheduling, improve the hit rate of pre-scheduling, and reduce service delay, empty packet rate and IOT (Interference over Thermal, uplink interference).

[0125] Optionally, determining that the sum of the initial transmission air interface time and the packet period time does not include the next SR time point means that the next SR time point is not within a time range consisting of the initial transmission air interface time and the above time and moment.

[0126] In step S606, based on the pre-scheduling interval, pre-scheduling time points of the DRB are generated at equal intervals.
