Background

In a New Radio (NR) system, the 3GPP NR protocol can support three service types: enhanced Mobile Broadband (eMBB), Ultra-reliable and Low Latency Communications (URLLC), and Enhanced Machine Type Communication (EMTC).

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The resource scheduling method provided by the present application can be applied to the application environment shown in fig. 1, where the base station 100 is in communication connection with the terminal device 200. The terminal 200 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, portable wearable devices, and the like. The base station may be, but not limited to, a macro base station, a micro base station, a small base station, and other types of base station devices, and the base station 100 may be a base station in a 5G network, a Customer Premise Equipment (CPE), and the like, and is not limited herein.

In an embodiment, as shown in fig. 2, a resource scheduling method is provided, which is described by taking the method as an example applied to the base station in fig. 1, and includes:

s101, determining a Downlink Control Information (DCI) scheduling format corresponding to a service type according to the service type of a service to be scheduled; the service type is one of enhanced mobile broadband eMBB service and ultra-high reliability and low delay communication URLLC service.

When the base station schedules resources for the UE, different resources may be scheduled according to different service types. The service type may be one of Enhanced Mobile broadband (eMBB) service and Ultra-reliable and Low Latency Communications (URLLC) service. The enhanced mobile broadband eMBB service is realized by adopting larger bandwidth and improving the base band rate, realizes higher transmission rate, and is mainly used for services such as high-speed data, high-definition video and the like. The URLLC service pursues lower delay and higher reliability, needs to realize extremely short delay by means of faster scheduling, and is mainly used for services such as car networking and remote control. The above-mentioned eMBB service and URLLC service may also be classified according to service characteristics, for example, URLLC service may be classified into high reliability service and low latency service.

The base station may determine a Downlink Control Information (DCI) scheduling format corresponding to the service type according to the service type of the service to be scheduled and a correspondence between a preset service type and the DCI scheduling format; for example, the DCI scheduling Format corresponding to the eMBB service is DCI Format0_1/1_1, and the DCI scheduling Format corresponding to the URLLC service is DCI Format0_2/1_ 2. Optionally, the eMBB service includes an eMBB uplink service and an eMBB downlink service; the URLLC service comprises a URLLC uplink service and a URLLC downlink service, the DCI scheduling Format corresponding to the eMMC uplink service can be DCI Format0-1, the DCI scheduling Format corresponding to the eMMC downlink service can be DCI Format1-1, the DCI scheduling Format corresponding to the URLLC uplink service can be DCI Format0-2, and the DCI scheduling Format corresponding to the URLLC downlink service can be DCI Format 1-2. The base station respectively corresponds to eBB uplink service, eBB downlink service, URLLC uplink service and URLLC downlink service through different DCI scheduling formats, and flexible scheduling of various types of services can be realized.

The DCI scheduling formats correspond to the service types one to one, and after receiving DCI, the terminal may determine which type of service is scheduled by the base station according to the DCI scheduling formats. The DCI scheduling format may also correspond to services with different characteristics in URLLC services and eMBB services, for example, a URLLC service may be divided into a high reliability service and a low delay service, and the base station may determine the DCI scheduling format corresponding to the low delay service when scheduling resources for the low delay service in the URLLC service.

S102, determining resource allocation information based on the service type and the pre-configured resource allocation parameters, wherein the resource allocation information is used for indicating available resources of User Equipment (UE); and resource configuration parameters URLLC configuration parameters corresponding to the URLLC service.

A base station may configure a resource configuration parameter for each User Equipment (User Equipment, UE for short), and in a scenario, the resource configuration parameter may further include an eMBB configuration parameter corresponding to an eMBB service; the eMMC configuration parameter is used for determining available resources of eMMC services, and the URLLC configuration parameter is used for determining available resources of URLLC services. In another application scenario, the URLLC configuration parameters include configuration parameters corresponding to a URLLC high-reliability service and configuration parameters corresponding to the URLLC low-delay service.

The foregoing eMBB configuration parameter may be used to indicate a time domain position of an available resource of an eMBB service, and may also be used to indicate a frequency domain range of the available resource of the eMBB service, which is not limited herein. The URLLC configuration parameter may be used to indicate a time domain position of an available resource of the URLLC service, and may also be used to indicate a frequency domain range of the available resource of the URLLC service, which is not limited herein.

The resource configuration parameter may be a configuration parameter of a service resource, or a configuration parameter of a control resource; accordingly, the available resource may be a service resource for transmitting downlink service data or receiving uplink service data, or may be a control resource for transmitting control information or receiving feedback information, which is not limited herein. The resource allocation information may be allocation information for indicating a service resource, or may be allocation information for indicating a control resource, and is not limited herein.

After determining the service type of the service to be scheduled, the base station may determine the available resource for scheduling the service according to the resource configuration parameter corresponding to the service type, and then the base station may generate the resource allocation information according to the scheduled resource.

S103, sending DCI to the UE by adopting a DCI scheduling format; the DCI carries resource allocation information of the UE.

On the basis of the above steps, the base station may send the resource allocation information of the UE to the UE through DCI using a DCI scheduling format matching the service type of the service to be scheduled.

The DCI information may include resources required for the UE to process the service to be scheduled, and may further include information such as a modulation scheme used by the UE to process the scheduling service. Optionally, the DCI further includes a priority of a service to be scheduled; wherein, the priority of the eMBB service is lower than that of the URLLC service. The base station may set the priority of the eMBB service to 0, the priority of the URLLC service to 1, and when the resource of the eMBB service scheduled by the base station for the UE conflicts with the resource of the URLLC service, the data of the URLLC service may be preferentially processed according to the priority parameter, for example, the data of the eMBB service with low priority is discarded.

After receiving the DCI, the terminal may first determine which type of service the base station schedules according to the scheduling Format of the DCI, for example, if the DCI scheduling Format of the DCI received by the terminal is DCI Format0_2/1_2, the UE may determine that the base station currently schedules the URLLC service. Further, the terminal may determine, according to the resource allocation information carried in the DCI, a resource for processing the service to be scheduled, and then process the service data on the resource.

In the resource scheduling method, the base station determines the downlink control information DCI scheduling format corresponding to the service type according to the service type of the service to be scheduled; then, determining resource allocation information based on the service type and the pre-configured resource allocation parameters, and sending DCI carrying the resource allocation information of the UE to the UE by adopting a DCI scheduling format; the service type is one of enhanced mobile broadband eMBB service and ultra-high reliability and low delay communication URLLC service; the resource configuration parameters include eBB configuration parameters corresponding to eBB services and URLLC configuration parameters corresponding to URLLC services. Because the base station determines different DCI scheduling formats according to different service types, eMBB service and URLLC service can be flexibly scheduled; furthermore, since the pre-configured resource configuration parameters include the URLLC configuration parameters corresponding to the URLLC service, appropriate resources can be allocated to the service to be scheduled according to the service type and the resource configuration parameters, so that the resource requirements of the URLLC service can be met, and the service performance can be guaranteed.

In an embodiment, on the basis of the foregoing embodiment, the URLLC configuration parameter includes a control resource configuration parameter and a traffic resource configuration parameter, where the control resource configuration parameter is used to indicate a control channel resource available to the UE; the service resource configuration parameter is used for indicating a scheduling strategy adopted when the base station schedules the service resource for the UE.

The control resource configuration parameter is used to indicate the control channel resource available to the UE. The control resource configuration parameter may be used to indicate an uplink control channel resource, and may also be used to indicate a downlink control channel resource. Optionally, the Control resource configuration parameter includes a Physical Uplink Control Channel (PUCCH) configuration parameter and a Physical Downlink Control Channel (PDCCH) configuration parameter.

The PUCCH configuration parameter may be used to indicate a PUCCH resource available to the UE, where the PUCCH resource may be used to send HARQ-ACK feedback to the base station, send an uplink Scheduling Request (SR) to the base station, and send Channel Status Information (CSI for short) to the base station. The PUCCH configuration parameters comprise a sub-slot length and a time interval set from downlink service data to uplink feedback; the PUCCH configuration parameters may further include a PUCCH resource set and a PUCCH format, for example, the PUCCH format may be format0, format1, and the like, and is used to indicate a symbol length of the PUCCH resource.

The PDCCH configuration parameter is used to indicate PDCCH resources available to the UE, and the PDCCH resources are used to carry scheduling and other control information, such as transport format, resource allocation, uplink scheduling grant, power control, and uplink retransmission information. The PDCCH configuration resources comprise a PDCCH resource region CORESET and at least one corresponding search space. The CORESET described above is only the frequency domain range and the time domain range required for PDCCH resources. The base station can set different aggregation levels according to the requirement of the URLLC service on PDCCH resources. For example, the aggregation level of URLLC traffic may be 8 or 16; the base station can generate a search space according to the aggregation level corresponding to the URLLC service. For services with different characteristics in URLLC service, such as high reliability service and low latency service, different parameters may be configured in the PDCCH configuration resource for the services with different characteristics. For example, high reliability traffic corresponds to CORESET1, CORESET1 corresponds to multiple search spaces; low latency traffic corresponds to CORESET2, CORESET2 corresponds to multiple search spaces; the number of search spaces in CORESET1 and CORESET2 may be the same or different.

The service resource configuration parameter is used to indicate a scheduling policy that is adopted when the base station schedules the service resource for the UE, and the service resource configuration parameter may be used to indicate a scheduling policy that is adopted when the base station schedules the uplink service resource for the UE, and may also be used to indicate a scheduling policy that is adopted when the base station schedules the downlink service resource for the UE. Optionally, the service resource configuration parameter includes a Physical Uplink Shared Channel (PUSCH) configuration parameter and a Physical Downlink Shared Channel (PDSCH) configuration parameter.

The PDSCH configuration parameters comprise PDSCH aggregation factors used for indicating the repeated sending times of downlink service data in a plurality of time slots; in addition, the PDSCH configuration parameters may also include a traffic mapping type, CSI-RS resource configuration, and the like. The PUSCH configuration parameters comprise time slot level repetition parameters or symbol level repetition sending parameters; the time slot level repetition parameter is used for indicating the repeated sending times of the uplink service data in a plurality of time slots; the symbol-level repetition parameter is used to indicate the number of repeated transmissions of uplink traffic data on symbols within a slot or slots.

The eMBB configuration parameters may include a control resource configuration parameter and a service resource configuration parameter. The control resource configuration parameters in the eMBB configuration parameters may also include PUCCH configuration parameters and PDCCH configuration parameters, and the service resource configuration parameters in the eMBB configuration parameters may also include PUSCH configuration parameters and PDSCH configuration parameters; the PDCCH configuration parameters in the eMBB configuration parameters may also include a CORESET corresponding to an eMBB service and a plurality of search spaces corresponding to the CORESET, the PDCCH aggregation level of the eMBB may be 1,2, or 4, and the base station may generate different search spaces for the aggregation level. The base station configures a larger aggregation level for the URLLC service, so that the URLLC service can obtain more PDCCH resources, and the PDCCH transmission reliability of the URLLC service is improved.

Specifically, the method for determining the base station search space may include: for the URLLC service, determining a plurality of search spaces corresponding to the URLLC service based on a first aggregation level corresponding to PDCCH resources of the URLLC service; and determining a plurality of search spaces corresponding to the eBB service based on the second aggregation level corresponding to the eBB service PDCCH resource. After determining the resource configuration parameters of the UE, the base station may send the resource configuration parameters to the UE through an RRC reconfiguration message.

In the RRC reconfiguration message, a frequency domain resource frequency and a number of continuous symbols of the PDCCH resource may be configured in a ControlResourceSet, where the number of continuous symbols indicates a time domain resource range of the PDCCH resource; and then, a search space is indicated by configuring a monitoring period and an offset monitorngslotperiodicityandoffset, wherein the monitoring period can be 1 time slot for both eMBB service and URLLC service. The above offset is used to indicate the starting position of the search space in CORESET, and for eMBB traffic, the first symbol within 1 slot is configured as the monitor symbol monitoringsymbols within slot. For high reliability service in URLLC service, 1 starting symbol is configured in 1 slot, for example, the monitoring symbol is {10000000000000}, which means that the base station can send DCI at the first symbol position in the slot, and the UE can listen to DCI at the first symbol position in the slot; for low-latency services in URLLC services, multiple start symbols are configured in 1 slot, for example, the monitoring symbol is {10101010101010}, which means that the base station can transmit DCI at multiple symbol positions in the slot, and the UE can monitor DCI at multiple symbols in the slot. Taking fig. 2A as an example, in one timeslot, the PDCCH resource for the eMBB service may be the first symbol, and for the URLLC low-latency service, the PDCCH resource may be two symbols.

According to the resource scheduling method, the base station respectively configures the control resource configuration parameters and the service resource configuration parameters aiming at the eMBB service and the URLLC service, so that the base station can configure appropriate resources for the control messages and the service data of the eMBB service and the URLLC service, and the reasonability of resource configuration is improved.

When the service to be scheduled is a downlink service, the base station may first determine a PDSCH resource corresponding to the downlink service, and send downlink service data to the UE through the PDSCH resource; determining PUCCH resources and PDCCH resources corresponding to downlink services, and then sending resource allocation information of PDSCH resources to UE through the PDCCH resources, so that the UE can determine the position of the PDSCH resources according to the PDCCH resources and receive downlink service data; the base station also indicates the PUCCH resource in which the UE returns the uplink control information, so that the UE generates an HARQ-ACK codebook after receiving the downlink service data and sends the HARQ-ACK codebook to the base station through the PUCCH resource. In the following embodiments, the procedure of scheduling PDSCH resources, PUCCH resources, and PDCCH resources for URLLC downlink traffic by the base station is described separately.

Fig. 3 is a flowchart illustrating a resource scheduling method in an embodiment, where the present embodiment relates to a manner in which a base station determines resource allocation information based on a service type and a pre-configured resource allocation parameter when the service type is a URLLC downlink service, where the resource allocation information is PDSCH resource allocation information, and on the basis of the above embodiment, as shown in fig. 3, the S102 includes:

s201, determining downlink service characteristics of the URLLC downlink service according to the attribute parameters of the URLLC downlink service; the attribute parameters of the URLLC downlink service comprise a packet error rate and a packet delay budget of the URLLC downlink service; the downlink service characteristics include downlink high reliability service or downlink low delay service.

When the base station schedules the URLLC downlink service of the UE, it may determine a suitable PDSCH resource for the downlink service characteristics of the URLLC service. Specifically, the base station may determine whether the service to be scheduled is a downlink high reliability service or a downlink low latency service according to the 5QI attribute of the downlink service.

Wherein, the attribute parameters of the URLLC downlink service include a packet error rate and a packet delay budget of the URLLC downlink service. The computer device can set a high reliability threshold and a low delay threshold, compare the attribute parameters of the URLLC downlink service with the above threshold values, and determine the downlink service characteristics of the service to be scheduled. Specifically, if the packet error rate of the URLLC downlink service is less than the preset high reliability threshold, determining that the URLLC downlink service is a downlink high reliability service; and if the packet delay budget of the URLLC downlink service is less than the preset low delay threshold, determining that the URLLC downlink service is the downlink low delay service.

S202, determining a downlink scheduling strategy matched with the downlink service characteristics according to the downlink service characteristics.

When the base station determines the appropriate PDSCH resources according to the downlink service characteristics of the URLLC service, the base station can determine the downlink scheduling strategy of the service to be scheduled according to the downlink service characteristics, and the appropriate downlink scheduling strategy is adopted to schedule the PDSCH resources for the UE.

For downlink high-reliability service, the base station can repeatedly send downlink service data to ensure that the UE can smoothly receive the downlink service data. Optionally, when the URLLC downlink service is a downlink high reliability service, the base station may determine that the downlink scheduling policy is a downlink timeslot aggregation scheduling policy; the downlink time slot aggregation scheduling strategy represents that the base station repeatedly sends downlink service data of the UE in a plurality of time slots.

For the downlink low-delay service, the base station can reduce the delay of the URLLC downlink service by reducing the interval between the downlink service data transmission and the uplink feedback of the service. Optionally, if the URLLC downlink service is a downlink low-delay service, the base station determines that the downlink scheduling policy is a self-contained time slot scheduling policy or a downlink sub-time slot scheduling policy; the self-contained time slot scheduling strategy represents that the base station schedules PDSCH resources in a special time slot; the downlink sub-slot scheduling strategy represents that the base station schedules PDSCH resources in one sub-slot. Specifically, the special time slot is a time slot in a frame structure, and includes both an uplink symbol and a downlink symbol, so that the base station can complete scheduling of PDSCH resources and PUCCH resources of URLLC downlink low-latency services in the same time slot. The base station can preferentially schedule the PDSCH resources in the special time slot, and if the special time slot in the current time slot has no available resources, the base station can further schedule the resources for the UE according to the downlink sub-time slot scheduling policy, so that the downlink service data of the UE can be sent in one sub-time slot without being delayed to be sent to the next sub-time slot. The length of the sub-slot may be 2 symbols, or may be 4 symbols or 7 symbols. If the sub-slot length is 7 symbols, the symbol length of the PDSCH resources scheduled by the base station for the URLLC downlink low-delay traffic may be 2 symbols, 4 symbols, or 7 symbols.

S203, determining PDSCH resource allocation information of the UE according to the resource configuration parameters and the downlink scheduling strategy.

After determining a downlink scheduling policy of the URLLC downlink service, the base station may determine the PDSCH resource of the UE according to the resource configuration parameter configured for the UE, and obtain PDSCH resource allocation information of the UE; and transmits downlink traffic data in the PDSCH resources.

Specifically, if the downlink scheduling policy is a downlink timeslot aggregation scheduling policy, determining PDSCH resource allocation information of the UE according to the PDSCH aggregation factor in the resource configuration parameter. The base station may determine the size of the PDSCH aggregation factor configured for the UE in the resource configuration parameter, that is, the number of times of repeated transmission of downlink service data; then, determining the PDSCH symbol length according to the size of the downlink service data of the UE, namely the size of PDSCH resources required by transmitting the downlink service data once; after obtaining the number of repeated transmissions and the size of resources required for a single transmission, the base station may determine PDSCH resource allocation information for the UE.

And if the downlink scheduling strategy is a downlink sub-time slot scheduling strategy, determining the PDSCH resource allocation information of the UE according to the sub-time slot length in the resource configuration parameter. The base station may determine the sub-slot length in the resource configuration parameter, and then determine the PDSCH resources of the UE within one sub-slot.

If the downlink scheduling policy is a self-contained time slot scheduling policy, the base station may directly schedule the PDSCH resources of the UE on the special time slot of the current frame structure.

Taking the frame structure shown in fig. 4 as an example, a frame structure with a period of 5ms is shown in the figure, and the slot configuration is 7D1S2U, which indicates that the slot includes 7 downlink slots, 1 special slot S slot and 2 uplink slots, where the S slot includes both uplink symbols and downlink symbols, and the S slot configuration may be 6D4G4U, which indicates that the S slot includes 6 downlink symbols, 4 GAP symbols and 4 uplink symbols. Of course, the frame structure configuration may be DDDSUUDDD, DSUU, DDDSU, DS, SU, and other types according to the requirements of different scenes. If the URLLC downlink service is a downlink high-reliability service, the base station may determine the number of repeated transmissions to be 4 times according to the PDSCH aggregation factor, and determine the PDSCH symbol length, then determine the PDSCH resources in one time slot in the first four time slots of the frame structure according to the PDSCH symbol length, respectively, obtain the PDSCH resource PDSCH1 of the UE, and then repeatedly transmit downlink service data in the four time slots. If the URLLC downlink service is a downlink low-delay service and the scheduling policy is determined to be a self-contained slot scheduling policy, the base station may determine PDSCH resource PDSCH2 of the UE in the special slot 7.

According to the resource scheduling method, when the URLLC downlink service is a downlink high-reliability service, the base station repeatedly sends downlink service data by determining the corresponding downlink scheduling strategy, so that the transmission reliability of the downlink service data is improved; when the URLLC downlink service is the downlink low-delay service, the base station reduces the downlink service delay by determining a corresponding downlink scheduling strategy, and ensures the data transmission performance of the downlink low-delay service.

Fig. 5 is a flowchart illustrating a resource scheduling method in an embodiment, where the present implementation relates to a manner in which a base station determines a PUCCH resource of a UE based on a service type when the service type is a URLLC downlink service, and on the basis of the foregoing embodiment, as shown in fig. 5, the foregoing method further includes:

s301, if the URLLC downlink service is the downlink high reliability service, determining PUCCH resources of the UE according to a time interval set from downlink service data to uplink feedback in the PUCCH configuration parameters.

The time interval from downlink service data to uplink feedback in the PUCCH configuration parameter may be a feedback interval range, and the base station may select a feedback interval in the feedback interval range and send the feedback interval to the UE through DCI, so that the UE determines the corresponding PUCCH resource according to one feedback interval in the feedback interval set after obtaining the PDSCH resource through PDCCH demodulation. Continuing with fig. 4 as an example, after receiving downlink service data in four slots, the UE may generate an HARQ-ACK codebook according to the downlink service data, and the HARQ-ACK codebooks corresponding to the HARQ-ACK codebooks are all sent to the base station through a PUCCH resource PUCCH1 in slot 8.

S302, if the URLLC downlink service is the downlink low-delay service, determining PUCCH resources of the UE in a self-contained time slot in which PDSCH resources of the UE are located.

If the URLLC downlink service is a downlink low-delay service, the PUCCH resource and the PDSCH resource configured for the UE by the base station are in the same time slot. Continuing with fig. 4 as an example, after receiving downlink service data in a special timeslot S, the UE may generate an HARQ-ACK codebook according to the downlink service data, and send the HARQ-ACK codebook corresponding to the HARQ-ACK codebook to the base station through an uplink symbol PUCCH resource PUCCH2 in the timeslot.

According to the resource scheduling method, the base station respectively determines the appropriate PUCCH resources aiming at the downlink high-reliability service and the downlink low-delay service in the URLLC downlink service, so that the UE can upload the uplink control information in the determined PUCCH resources, and the transmission reliability of the URLLC downlink service is improved.

Fig. 6 is a flowchart illustrating a resource scheduling method in an embodiment, where the present embodiment relates to a manner in which a base station determines a PDCCH resource of a UE and then transmits DCI through the PDCCH resource, and on the basis of the foregoing embodiment, as shown in fig. 6, the foregoing S103 includes:

s401, determining a target CORESET corresponding to the service type in the resource configuration parameters.

Specifically, the base station may determine, according to the service type of the service to be scheduled, which CORESET the service type corresponds to in the resource configuration parameter, and determine the service type as the target CORESET.

S402, acquiring the data size of the downlink control information of the service to be scheduled, and determining the aggregation level matched with the data size.

S403, determining a search space corresponding to the aggregation level matched with the data size as a PDCCH resource of the UE;

further, the base station may select a suitable aggregation level according to the data size of the downlink control information of the service to be scheduled, and determine a search space corresponding to the aggregation level in the target CORESET as the PDCCH resource of the UE.

S404, transmitting the DCI to the UE through the PDCCH resource of the UE.

Based on the above steps, the base station may send DCI carrying resource allocation information to the UE on the PDCCH resource.

It should be noted that after the base station sends the PDCCH configuration parameters to the UE, the UE needs to monitor all the services in the CORESET corresponding to each service type to obtain the DCI sent by the base station when the UE does not determine which type of service the base station schedules.

According to the resource scheduling method, the base station can configure a higher aggregation level for the URLLC service, so that the URLLC service can obtain more PDCCH resources, and the PDCCH transmission reliability of the URLLC service is improved.

Fig. 7 is a flowchart illustrating a resource scheduling method in an embodiment, where the present embodiment relates to a manner in which a base station determines resource allocation information based on a service type and a pre-configured resource allocation parameter when the service type is a URLLC uplink service, where the resource allocation information is PUSCH resource allocation information, and on the basis of the above embodiment, as shown in fig. 7, the S102 includes:

s501, determining uplink service characteristics of the URLLC uplink service according to the attribute parameters of the URLLC uplink service; the attribute parameters of the URLLC uplink service comprise a packet error rate and a packet delay budget of the URLLC uplink service; the uplink service characteristics comprise uplink high reliability service or uplink low delay service.

The method for determining the uplink service characteristics of the uplink service by the base station according to the attribute parameters of the URLLC uplink service is similar to the method for determining the downlink service characteristics in S201, and the base station can determine an appropriate PUSCH resource for the uplink service characteristics of the URLLC service when scheduling the URLLC uplink service of the UE. Specifically, the base station may determine whether the service to be scheduled is an uplink high reliability service or an uplink low latency service according to the 5QI attribute of the uplink service.

Wherein, the attribute parameters of the URLLC uplink service include a packet error rate and a packet delay budget of the URLLC uplink service. The computer device can set a high reliability threshold and a low delay threshold, compare the attribute parameters of the URLLC uplink service with the above threshold values, and determine the uplink service characteristics of the service to be scheduled. Specifically, if the packet error rate of the URLLC uplink service is less than the preset high reliability threshold, determining that the URLLC uplink service is an uplink high reliability service; and if the packet delay budget of the URLLC uplink service is smaller than the preset low delay threshold, determining that the URLLC uplink service is the uplink low delay service.

And S502, determining an uplink scheduling strategy matched with the uplink service characteristics according to the uplink service characteristics.

When the base station determines a suitable PUSCH resource according to the uplink service characteristics of the URLLC service, an uplink scheduling strategy of the service to be scheduled can be determined according to the uplink service characteristics, and the PUSCH resource is scheduled for the UE by adopting the suitable uplink scheduling strategy.

For the uplink high-reliability service, the base station can instruct the UE to repeatedly send uplink service data, so as to ensure that the base station can smoothly receive the uplink service data. Optionally, when the URLLC uplink service is an uplink high reliability service, the base station may determine that the uplink scheduling policy is an uplink timeslot aggregation scheduling policy or a symbol repetition scheduling policy; the uplink time slot aggregation scheduling strategy represents that a base station indicates UE to repeatedly send uplink service data in a plurality of time slots; the symbol repeated scheduling strategy represents that the base station instructs the UE to repeatedly send the uplink service data in a plurality of symbols.

For the uplink low-delay service, the base station can reduce the delay of the URLLC uplink service by reducing the interval between the downlink control information of the service and the uplink service data. Optionally, if the URLLC uplink service is an uplink low-delay service, determining that the uplink scheduling policy is an uplink sub-slot scheduling policy; and the uplink sub-slot scheduling strategy represents that the base station indicates the UE to send uplink service data in one sub-slot.

The base station can schedule resources for the UE according to the uplink sub-time slot scheduling strategy, so that uplink service data of the UE can be sent in one sub-time slot without being delayed to be sent in the next sub-time slot. The length of the sub-slot may be 2 symbols, or may be 4 symbols or 7 symbols. If the length of the sub-slot is 7 symbols, the length of the symbol of the PUSCH resource scheduled by the base station for the URLLC uplink low-latency service may be 2 symbols, 4 symbols, or 7 symbols.

As shown in fig. 8, if the URLLC uplink service is a high-reliability service, the UE may repeatedly transmit the uplink service data in the time slot for 2 times through a symbol repetition scheduling policy, where the symbol length corresponding to each transmission is 4 symbols, and corresponds to the PUSCH resource PUSCH1 in the middle; if the URLLC uplink service is an uplink low-delay service, the UE may send uplink service data in one sub-slot through an uplink sub-slot scheduling policy, where the length of the sub-slot may be 7 symbols, and corresponds to PUSCH 2; the sub-slot length may be 2 symbols and corresponds to PUSCH 3.

S503, determining PUSCH resource allocation information of the UE according to the resource configuration parameters and the uplink scheduling strategy.

After determining the uplink scheduling policy, the base station may determine the PUSCH resource of the UE according to the resource configuration parameter, and obtain PUSCH resource allocation information of the UE.

And if the uplink scheduling strategy is an uplink time slot aggregation scheduling strategy, determining the PUSCH resource allocation information of the UE according to the time slot level repetition parameters in the resource configuration parameters.

And if the uplink scheduling strategy is a symbol repeated scheduling strategy, determining the PUSCH resource allocation information of the UE according to the symbol-level repeated transmission parameters in the resource configuration parameters.

Correspondingly, after the UE receives the DCI, if the DCI scheduling format indicates that the service type scheduled by the base station is the URLLC uplink high reliability service, the base station may determine, in the resource configuration parameter, whether the base station is configured as a slot-level repetition parameter or a symbol-level repetition parameter. If the base station configures the slot level repetition parameter, the UE may determine that the PUSCH resource scheduled by the base station for the UE is a resource for the UE to transmit uplink service data to the base station through the uplink slot aggregation scheduling policy, and the UE may repeatedly transmit the uplink service data in the PUSCH resource according to the slot level repetition parameter. If the base station configures the symbol-level repetition parameter, the UE may determine that the PUSCH resource scheduled by the base station for the UE is a resource for the UE to transmit uplink service data to the base station through the symbol repetition scheduling policy, and the UE may repeatedly transmit the uplink service data in the PUSCH resource according to the symbol-level repetition parameter.

According to the resource scheduling method, the base station respectively determines the appropriate PUSCH resources aiming at the uplink high-reliability service and the uplink low-delay service in the URLLC uplink service, so that the UE can adopt the corresponding uplink scheduling strategy to transmit the uplink service data in the determined PUCCH resources, and the transmission performance of the uplink service data is guaranteed.

Further, the base station may transmit DCI to the UE in the DCI scheduling format.

The implementation principle and technical effect of the foregoing embodiment are similar to the resource scheduling method corresponding to the base station side, and are not described herein again.

Fig. 11 is a flowchart illustrating a resource scheduling method in an embodiment, where the present implementation relates to a manner in which a terminal device sends uplink service data when a service type is a URLLC uplink service, where the resource allocation information is PUSCH resource allocation information, and on the basis of the foregoing embodiment, as shown in fig. 11, the method further includes:

Specifically, when the packet error rate of the URLLC uplink service is less than the preset high reliability threshold, the UE determines that the URLLC uplink service is an uplink high reliability service; and when the packet delay budget of the URLLC uplink service is smaller than a preset low delay threshold, determining the URLLC uplink service as the uplink low delay service.

S802, determining an uplink scheduling strategy matched with the uplink service characteristics according to the uplink service characteristics.

After the UE receives the DCI, if the DCI scheduling format indicates that the service type scheduled by the base station is the URLLC uplink high reliability service, the base station may determine, in the resource configuration parameter, whether the base station is configured as a slot-level repetition parameter or a symbol-level repetition parameter. If the URLLC uplink service is an uplink high-reliability service and the resource configuration parameters comprise time slot level repetition parameters, determining that the uplink scheduling strategy is an uplink time slot aggregation scheduling strategy; the uplink time slot aggregation scheduling strategy represents that uplink service data are repeatedly sent in a plurality of time slots; if the URLLC uplink service is an uplink high-reliability service and the resource configuration parameters comprise symbol-level repetition parameters, determining that the uplink scheduling strategy is a symbol repetition scheduling strategy; the symbol repetition scheduling strategy represents that uplink service data is repeatedly transmitted in a plurality of symbols.
