Description

Resource scheduling method, device, equipment and storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to a resource scheduling method, apparatus, device, and storage medium.

Background

1.4M + SUL (1.4M bandwidth and supplemental uplink, SUL)) is a technology for moderate resource integration to meet industry applications, which is proposed on the basis of the current Long Term Evolution (LTE) protocol. The standard frequency band of a 1.4M frequency-division duplex (FDD) mode may be used to support a trunking service or a low-rate service, and the SUL technology aggregates scattered uplink carriers by carrier aggregation to meet the requirement of an uplink high-rate service.

In the prior art, a typical application scenario of 1.4M + SUL is a combination of 1.4M FDD + SUL 8M, or a combination of 1.4M FDD + SUL 4M. According to the 3GPP LTE protocol, a Physical Downlink Control Channel (PDCCH) of 1.4M FDD can maximally use 4 Orthogonal Frequency Division Multiplexing (OFDM) symbols (about 6 Control Channel Elements (CCEs) with aggregation level 1) per subframe, and aims to share channel resources (including uplink 6 Resource Blocks (RBs) and downlink 6 RBs) over a 1.4M bandwidth. For a scenario of a combination of 1.4M FDD + SUL 8M or a combination of 1.4M FDD + SUL4M, the maximum available 4 OFDM symbols of the PDCCH for 1.4M FDD on each subframe are used for allocating shared channel resources on a 1.4M bandwidth, and besides, the resource allocation for the SUL shared channel (42 uplink RBs corresponding to 8M SUL or 21 RBs corresponding to 4ms ul) needs to be allocated.

If the PDCCH symbol number is flexibly adjusted according to scheduling, the problem of insufficient shared channel resources can be solved, but the shared channel resources of the cell are interfered by the service channel of the adjacent cell, so that the problem of unstable system exists.

The embodiments of the present application do not limit the spectrum resources used between the network device and the terminal device.

First, a brief description is given of an application scenario of the embodiment of the present application.

In the existing communication system, terminal devices of some industry clients are limited by frequency resources and service features, and cannot establish a proper cluster system according to the existing 3GPP or other standard protocols.

It can be understood that the standard frequency band of 1.4M FDD may be used to support trunking service or low-rate service, that is, resource allocation is performed by using shared channel resources on 1.4M bandwidth, and the SUL technology refers to aggregating scattered uplink carriers by a carrier aggregation method to meet the requirement of uplink high-rate service, such as video upload, picture upload, and the like.

In general, a PDCCH for 1.4M FDD has a maximum available 4 OFDM symbols (about 6 CCEs with aggregation level 1) per subframe, and these 4 OFDM symbols can be used for allocation of shared channel resources over a 1.4M bandwidth, and include 6 RBs for uplink and 6 RBs for downlink in total. However, in a scenario of 1.4M + SUL, for example, a combination of 1.4M FDD + SUL 8M, or a combination of 1.4M FDD + SUL4M, the maximum 4 OFDM symbols of the PDCCH of 1.4M FDD on each subframe need to be allocated for resources of the SUL shared channel (8M SUL corresponds to 42 uplink RBs, or 4M SUL corresponds to 21 RBs) in addition to allocation of shared channel resources on a 1.4M bandwidth, which may severely restrict the number of users and traffic conditions under a single cell, and especially for a part of users distributed in a region with poor cell signals, each scheduling of the users occupies more CCEs, which may cause a problem of more deficient control channels and insufficient shared channel resources. Aiming at the problem, one solution is that the PDCCH symbol number can be flexibly adjusted according to scheduling, the number of CCEs of a control channel can be expanded, and the problem of insufficient shared channel resources is solved, but the PDCCH symbol number can be flexibly adjusted according to scheduling, which causes interference of a service channel of an adjacent cell to the shared channel of the cell, and the problem of system instability exists.

In order to solve the problem, the embodiment of the present application provides a resource scheduling method, where a network device obtains an identifier of a terminal of a resource to be scheduled, where the terminal includes a first type of terminal that supports a SUL capability and/or a second type of terminal that does not support the SUL capability, and performs resource scheduling for the terminal of the resource to be scheduled according to a type of the terminal and a preset rule; the preset rule is used for determining a PDCCH for resource scheduling for the terminal. In the technical scheme, the scheduling strategy for the terminal is determined according to the type of the terminal and the preset rule, so that the PDCCH of the terminal is distributed in a staggered manner, the interference to the PDCCH is effectively avoided, and the system stability is improved.

The technical solution of the present application will be described in detail below with reference to specific examples. It should be noted that the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

Before describing the technical solution of the present application in detail, first, a terminal and a terminal resource pool related to the technical solution of the present application are briefly introduced.

In the 1.4M + SUL scenario, in order to facilitate determining whether the terminal supports the SUL capability, a field may be added in the signaling to characterize whether the terminal supports the SUL capability. Alternatively, a terminal supporting the SUL capability is referred to as a SUL terminal. For convenience of description, in the embodiments of the present application, a terminal supporting SUL capability (SUL terminal) is referred to as a first-type terminal, and a general terminal not supporting SUL capability is referred to as a second-type terminal.

Optionally, in a scenario of 1.4M + SUL, since the terminal accessing the network device may include both a terminal supporting the SUL capability and a terminal not supporting the SUL capability, and may also include both a terminal supporting the SUL capability and a terminal not supporting the SUL capability, in order that the network device can flexibly schedule the terminal on the PDCCH, the network device divides the resource pool of the terminal into a common terminal resource pool and a SUL terminal resource pool.

The maximum number of PDCCH symbols in the common terminal resource pool is 4, the maximum number of PDCCH symbols in the SUL terminal resource pool is 6, and compared with the common terminal resource pool, the SUL terminal resource pool can increase about 50% of CCE resources of a control channel.

Specifically, the determination method of the number of available OFDM symbols on the PDCCH is as follows:

(1) for the subframe 1 and the subframe 6 with the frame type of 2, when the number of downlink RBs is more than 10, the number of OFDM symbols on the PDCCH can take values of 1 and 2; when the number of downlink RBs is less than or equal to 10, the number of OFDM symbols on the PDCCH can take the value of 2;

(2) for a multicast/multicast single frequency network (MBSFN) subframe which is configured with 1 or 2 dedicated antenna ports and supports a Physical Downlink Shared Channel (PDSCH) on a carrier, when the number of downlink RBs is greater than 10, the number of OFDM symbols on the PDCCH may take values of 1 and 2; when the number of downlink RBs is less than or equal to 10, the number of OFDM symbols on the PDCCH can take the value of 2;

(3) for an MBSFN subframe which is configured with 4 special antenna ports and supports a PDSCH on a carrier, when the number of downlink RBs is more than 10, the number of OFDM symbols on the PDCCH can take a value of 2; when the number of downlink RBs is less than or equal to 10, the number of OFDM symbols on the PDCCH can take the value of 2;

(4) for the subframe which does not support PDSCH on the carrier, when the number of downlink RBs is more than 10, the number of OFDM symbols on the PDCCH can take the value of 0; when the number of downlink RBs is less than or equal to 10, the number of OFDM symbols on the PDCCH can take the value of 0;

(5) for a non-MBSFN subframe (except for the subframe 6 with the frame type of 2) configured with a positioning reference signal, when the number of downlink RBs is more than 10, the number of OFDM symbols on a PDCCH can take values of 1,2 and 3; when the number of downlink RBs is less than or equal to 10, the number of OFDM symbols on the PDCCH can take values of 2 and 3;

(6) for other cases, when the number of downlink RBs is greater than 10, the number of OFDM symbols on the PDCCH may take values of 1,2, and 3; when the number of downlink RBs is less than or equal to 10, the number of OFDM symbols on the PDCCH may take values of 2,3,4,5, and 6.

Fig. 2 is a flowchart illustrating a first embodiment of a resource scheduling method according to an embodiment of the present application. The method is suitable for network equipment. As shown in fig. 2, the method may include the steps of:

and step 21, acquiring the identifier of the terminal of the resource to be scheduled, wherein the terminal of the resource to be scheduled comprises a first type terminal supporting the SUL capability and/or a second type terminal not supporting the SUL capability.

Typically, the terminal device has a signaling identifying the terminal capabilities supported by the terminal. Therefore, in this embodiment, when determining to schedule resources for a terminal device, a network device first obtains an identifier of a terminal of the resources to be scheduled, and then obtains a field of the terminal carrying the SUL according to the identifier of the terminal, and then determines whether the terminal supports the SUL capability according to the field of the SUL.

Optionally, in this embodiment, the terminal of the resource to be scheduled, which is obtained by the network device, may be a first type terminal capable of supporting the SUL capability, may also be a second type terminal that does not support the SUL capability, and may also include the first type terminal that supports the SUL capability and the second type terminal that does not support the SUL capability at the same time.

It is to be understood that whether the terminal supports the SUL capability may be determined as follows:

in practical applications, when a terminal accesses a network device, for example, first network access or cell handover, the terminal generally needs to report capabilities supported by the terminal to the network device. For example, in a scenario of 1.4M + SUL, the terminal reports the capability information to inform the network device of its supported capability. Optionally, the capability information may include a bit for indicating whether the terminal supports the SUL capability, and thus, the capability information is used to determine a PDCCH for scheduling resources for the terminal.

Specifically, a field indicating the SUL-capabilities of the terminal (UE-SULcapability) is added to the terrestrial radio access capabilities (UE-EUTRA-capabilities ie) in 3GPP 36331, and when the value of the field is TRUE, it indicates that the terminal supports the SUL capabilities, and when the UE-SULcapability field is not carried by the terminal or the value of the field is FALSE, it indicates that the terminal is a normal terminal and does not support the SUL capabilities.

Accordingly, after the terminal reports the capability information, the network device may receive the capability information reported by each terminal, and determine the type of the terminal according to a bit included in the capability information and used for indicating whether the terminal supports the SUL capability.

Illustratively, if a bit value included in the capability information for indicating whether the terminal supports the SUL capability is TRUE, the terminal is determined to be a first type of terminal supporting the SUL capability, otherwise, the terminal is determined to be a second type of terminal not supporting the SUL capability. After the network device determines the type of the terminal, the network device may further determine a preset rule for the terminal according to a preset scheduling policy.

Furthermore, in order to enable the terminal to accurately perform data transmission, after determining the scheduling information for the terminal, the network device may feed back the preset rule to the terminal on the PDCCH, so that the terminal can receive the preset rule in time. The network equipment feeds the scheduling information back to the terminal in time, and a foundation is laid for data transmission between the terminal equipment and the network equipment.

Step 22, scheduling resources for the terminal of the resources to be scheduled according to the type of the terminal and a preset rule; the preset rule is used for determining a PDCCH for resource scheduling for the terminal.

Optionally, in this embodiment, after obtaining the identifier of the terminal, the network device first determines the type of the terminal, then determines a preset rule of a PDCCH for performing resource scheduling on the terminal, and finally performs resource scheduling on the terminal of the resource to be scheduled together according to the type of the terminal and the preset rule.

For example, in this embodiment, as can be seen from the analysis in the step 21, the terminal may be a first type terminal capable of supporting the SUL capability, or may be a second type terminal not supporting the SUL capability, or may include both the first type terminal supporting the SUL capability and the second type terminal not supporting the SUL capability, so that the type of the terminal may be the first type or the second type.

For example, in this embodiment, the preset rule may include any one of the following:

(1) and scheduling resources for the terminal according to the user priority and/or the service priority.

In this embodiment, when performing resource scheduling on the terminal, the network device may determine, based on the user priority and/or the service priority corresponding to the terminal, whether the network device considers the user priority of the terminal first or considers the service priority of the terminal first in the specific implementation, which may be determined according to different requirements. For a specific implementation scheme of how to schedule resources for a terminal according to a user priority and/or a service priority, reference may be made to the following description in the embodiments shown in fig. 4 and fig. 5, which is not described herein again.

(2) And carrying out resource scheduling on the terminal according to the number of the preset PDCCH symbols.

Illustratively, the preset rule may be a fixed PDCCH symbol number.

Specifically, if the PDCCH symbol number is flexibly adjusted according to scheduling, the resources of the PDCCH may be interfered by a neighboring cell service channel, and at this time, in order to reduce the interference of the neighboring cell service channel on the control channel (PDCCH) of the local cell, the demodulation capability of the control channel of the weak coverage area may be enhanced, that is, the PDCCH symbol number is selected to be the maximum.

For the SUL terminal resource pool, the number of PDCCH symbols selected may be 6; for a general terminal resource pool, the number of selected PDCCH symbols may be 4.

(3) And determining the CCE initial number when the resource scheduling is carried out on the terminal according to the number of the used PDCCH symbols.

In this embodiment, the preset rule may be flexibly adjusted according to PDCCH CCE resources.

Optionally, for a scenario in which the PDCCH symbol number is 4, the preset rule may be summarized as the following cases:

a1: if all terminals can be scheduled by the CCE on 1 PDCCH symbol, the symbol number initially allocated by the CCE is a result obtained by calculating a remainder from 4 and the number of Physical Cell Identifiers (PCIs), and may be simply labeled as PCI mod 4.

A2: if the CCE of 2 PDCCH symbols can schedule all terminals, the symbol number assigned at the beginning of the CCE is the result obtained by subtracting PCI from 2, and may be simply labeled as PCI mod 2.

A3: if all terminals can be scheduled by the CCEs on 2 or more PDCCH symbols, the predetermined rule is to start to allocate CCEs from the first PDCCH symbol.

Optionally, for a scenario in which the PDCCH symbol number is 6, the preset rule may be summarized as the following cases:

b1: if all terminals can be scheduled by the CCE on 1 PDCCH symbol, the initial CCE allocation symbol number is the result obtained by subtracting the number of PCIs from 6, and may be simply denoted as pcmimod 6.

B2: if all terminals can be scheduled by the CCE on 2 PDCCH symbols, the CCE initial allocation symbol number is the result obtained by calculating the remainder from the number of PCIs and 3, and may be simply labeled as pcmimod 3.

B3: if all terminals can be scheduled by the CCE on 3 PDCCH symbols, the CCE initial allocation symbol number is the result obtained by subtracting the remainder from 2 and the number of PCImod 2, and may be simply labeled as PCImod 2.

B4: if all terminals can be scheduled by the CCEs on 3 or more PDCCH symbols, the predetermined rule is to start to allocate CCEs from the first PDCCH symbol.

(4) And carrying out resource scheduling on the terminal according to the uplink scheduling priority, wherein the uplink scheduling priority is determined according to the CCE efficiency.

Optionally, in this embodiment, in order to improve the scheduling efficiency of each CCE on the control channel, the network device may determine the uplink scheduling priority of the terminal based on the efficiency of the CCE, and then perform resource scheduling on the terminal according to the uplink scheduling priority.

It can be understood that the embodiment of the present application does not limit the specific implementation manner of the preset rule, and the specific implementation manner can be determined according to the actual situation, which is not described herein again.

According to the resource scheduling method provided by the embodiment of the application, network equipment acquires the identifier of a terminal of a resource to be scheduled, the terminal comprises a first type terminal supporting the SUL capability and/or a second type terminal not supporting the SUL capability, and the resource scheduling is carried out on the terminal of the resource to be scheduled according to the type of the terminal and a preset rule; the preset rule is used for determining a PDCCH for resource scheduling for the terminal. In the technical scheme, the scheduling strategy for the terminal is determined according to the type of the terminal and the preset rule, so that the PDCCH of the terminal is distributed in a staggered manner, the interference to the PDCCH is effectively avoided, and the system stability is improved.

For example, in a possible design of the foregoing embodiment, fig. 3 is a flowchart illustrating a second embodiment of a resource scheduling method provided in the embodiment of the present application. Referring to fig. 3, the preset rule includes: when the terminal is scheduled with resources according to the uplink scheduling priority, the method may further include the following steps:

and 31, acquiring the data quantity which can be scheduled by the terminal on the current subframe and the used CCE aggregation level.

In this embodiment, the network device first determines, according to the capability of the terminal, the data amount that the terminal device can schedule on the current subframe and the CCE aggregation level used by the terminal device.

And step 32, determining the efficiency of the CCE used by the terminal according to the data quantity which can be scheduled by the terminal on the current subframe and the used CCE aggregation level.

The efficiency of the CCE used by the terminal is a ratio of a data amount that the terminal can schedule on the current subframe to a CCE aggregation level used by the terminal.

And step 33, determining the uplink scheduling priority of each terminal according to the CCE efficiency used by each terminal.

In this embodiment, after the network device calculates the efficiency of the CCE used by each terminal, the network device may rank the efficiencies of the CCEs used by all terminals to obtain the uplink scheduling priority of each terminal. For example, the efficiencies of the CCEs used by the terminals are sorted in descending order, and the uplink scheduling priority of each terminal is determined according to the efficiency of the CCEs used by the terminals.

In the resource scheduling method provided in this embodiment, the network device determines the efficiency of the CCE used by the terminal according to the acquired data amount that the terminal can schedule on the current subframe and the CCE aggregation level used by the terminal, and then determines the uplink scheduling priority of each terminal according to the efficiency of the CCE used by each terminal. The technical scheme improves the scheduling efficiency of each CCE on the control channel.

For example, in another possible design of the foregoing embodiment, fig. 4 is a flowchart illustrating a third embodiment of a resource scheduling method provided in this embodiment. Referring to fig. 4, the preset rule includes: when performing resource scheduling on the terminal according to the user priority and/or the service priority, the step 22 may be implemented by the following steps:

and step 41, dividing the terminal into at least one type of terminal according to the type of the terminal.

Optionally, in this embodiment, the network device first obtains the terminal capability level reported by the terminal, then determines the type of the terminal according to the terminal capability level of the terminal, and classifies the terminal of the resource to be scheduled to obtain at least one type of terminal.

For example, terminals may be classified into a first type of terminal that supports SUL and a second type of terminal that does not support SUL capability according to whether the terminals support SUL capability.

And step 42, determining the resource scheduling sequence for each type of terminal according to the user priority corresponding to each type of terminal.

Optionally, after dividing all the terminals of the resources to be scheduled into at least one type of terminals, the network device sorts the priorities of the terminals according to the user priorities corresponding to the terminals, and determines the resource scheduling order for the terminals.

And step 43, determining the resource scheduling sequence for each terminal in the same class of terminals according to the service priority.

For example, in this embodiment, the network device may determine, according to a service priority preset in the system, a sequence in which the resource scheduling is performed for each terminal in the same class of terminals with respect to a service requested by each terminal in the same class of terminals.

And step 44, scheduling the resource for the terminal of the resource to be scheduled according to the sequence of scheduling the resource for each type of terminal and the sequence of scheduling the resource for each terminal in the same type of terminal.

In the embodiment, after determining the resource scheduling sequence of each type of terminal and the resource scheduling sequence for each terminal in the same type of terminal, the network device sorts all the terminals, so as to perform resource scheduling on the terminals to be scheduled resources based on the determined terminal sequence.

According to the technical scheme of the embodiment of the application, the terminal can be reasonably scheduled, and resources of the PDCCH are utilized to the maximum extent.

For example, in another possible design of the foregoing embodiment, fig. 5 is a flowchart illustrating a fourth embodiment of a resource scheduling method provided in the embodiment of the present application. Referring to fig. 5, the preset rule includes: when performing resource scheduling on the terminal according to the user priority and/or the service priority, the step 22 may be implemented by the following steps:

and step 51, dividing the terminal into a plurality of terminal sets according to the service priority, and determining the resource scheduling sequence for each terminal set, wherein the terminal in each terminal set requests the same type of service.

In this embodiment, the network device may first divide all terminals that require resources to be scheduled according to services requested by the terminals, group the terminals that require the same type of services into the same terminal set, and then determine the order of scheduling resources for each terminal set according to service priorities preset in the system and in the order from high to low of the service priorities.

And step 52, classifying the terminals in each terminal set according to the type of each terminal in each terminal set to obtain at least one type of terminal included in each terminal set.

In this embodiment, for each terminal set, the network device first obtains a terminal capability level reported by the terminal, then determines a type of the terminal according to the terminal capability level of the terminal, and then classifies the terminals in each terminal set to obtain at least one type of terminal included in each terminal set.

And step 53, determining the resource scheduling sequence for each type of terminal according to the user priority corresponding to each type of terminal in each terminal set.

Optionally, after determining at least one type of terminal included in each terminal set for each terminal set, the network device may sort the priorities of each type of terminal according to the user priorities corresponding to each type of terminal, and determine the order of resource scheduling for each type of terminal.

And step 54, scheduling the resources for the terminal of the resources to be scheduled according to the sequence of scheduling the resources for each terminal set and the sequence of scheduling the resources for each type of terminal in each terminal set.

In the embodiment, after determining the sequence of resource scheduling for each terminal set and the sequence of resource scheduling for each type of terminal in each terminal set, the network device may rank all the terminals, so as to perform resource scheduling on the terminals to be scheduled resources based on the determined terminal sequence.

The technical scheme of the embodiment of the application can also realize reasonable scheduling of the terminal and can also maximally utilize the resources of the PDCCH.

Exemplarily, on the basis of the foregoing embodiments, fig. 6 is a schematic flowchart of a fifth embodiment of a resource scheduling method provided in the embodiment of the present application. Referring to fig. 6, the step 22 may be implemented by:

and step 61, determining the type of the terminal of the resource to be scheduled.

In this embodiment, after acquiring the identifier of the terminal of the resource to be scheduled, the network device may first determine the type of the terminal of the resource to be scheduled according to the terminal capability information uploaded by the terminal, and then determine the scheduling policy for the terminal.

Optionally, according to the execution result of step 61, the resource scheduling method of this embodiment may be implemented by the following three possible designs:

referring to fig. 6, in one possible design of the present application, when the terminals to schedule resources include only the first type of terminals, after step 61, the following step 62 is performed:

and step 62, adopting the SUL terminal resource pool with the PDCCH symbol being maximum 6, and scheduling the resources of the first class of terminals according to a preset rule.

As an example, if the terminal to be scheduled with resources only includes a first type of terminal that supports the SUL capability, in order to ensure that the network device can schedule all terminals on the resources of the PDCCH, the network device may perform resource scheduling on the first type of terminal by using a SUL terminal resource pool according to a preset scheduling policy, that is, a preset rule. Specifically, the maximum number of PDCCH symbols in the SUL terminal resource pool is 6, so the network device can flexibly adjust the number of the PDCCH symbols in the OFDM symbols 2,3,4,5, and 6 according to actual needs, thereby avoiding the problem of insufficient number of PDCCH OFDM symbols in the cell.

In another possible design of the present application, when the terminal to schedule resources includes only the second class of terminals, after step 61, the following step 63 is performed:

and 63, adopting a common terminal resource pool with the maximum PDCCH symbol of 4, and scheduling the resources of the first class of terminals according to a preset rule.

For example, the network device may indicate the number of PDCCH OFDM symbols of a cell through a Physical Control Format Indicator Channel (PCFICH), where the maximum bandwidth of a normal terminal resource pool can only support 4 OFDM symbols, and the maximum bandwidth of a SUL terminal resource pool can support 6 OFDM symbols.

In this embodiment, if the network device schedules on the subframe and only the terminal that the network device needs to schedule has a data scheduling request for the second class of terminals that do not support the SUL capability, the terminal may be scheduled according to a preset rule by using a common terminal resource pool, and since the number of PDCCH symbols in the common terminal resource pool is 4 at most, the network device may be flexibly adjusted according to actual needs in OFDM symbols 2,3, and 4.

In another possible design of the present application, when the terminals of the resources to be scheduled include a first class terminal and a second class terminal, after step 61, the following steps are performed:

step 64, judging whether the resources when the PDCCH symbols are at most 4 can be scheduled for all terminals, if so, executing step 65; if not, go to step 66.

For example, in this embodiment, if the network device schedules on the subframe and the terminal that the network device needs to schedule has both the second class of terminal that supports the SUL capability and the second class of terminal that does not support the SUL capability, the terminal is selected according to the scheduling policy, so that it is ensured that the control channel resource of the PDCCH is maximally utilized.

Specifically, when the terminals to be scheduled by the network device include a first type terminal and a second type terminal, it is first determined whether resources are sufficient when the PDCCH symbol is at most 4, that is, whether resources can be scheduled for all terminals when the PDCCH symbol is at most 4, and then subsequent operations are performed according to the determination result.

And step 65, adopting a common resource pool with the maximum PDCCH symbol of 4, and scheduling the resources of the first class terminal and the second class terminal according to a preset rule.

As an example, if the resources of the PDCCH with the maximum symbol of 4 can be scheduled for all terminals, in order to improve the utilization rate of the resources on the PDCCH, a common terminal resource pool with the maximum symbol of 4 may be used, and resource scheduling is performed for the first class of terminals and the second class of terminals based on a preset rule in the system.

Step 66, judging whether the resources with the maximum PDCCH symbol of 4 can finish scheduling all the first class terminals; if yes, go to step 67, otherwise go to step 68.

As another example, if the resources of the PDCCH with the maximum symbol of 4 cannot schedule all terminals, it may be determined whether the resources of the PDCCH with the maximum symbol of 4 can schedule all the first type terminals, and then perform resource scheduling according to the determination result.

And 67, adopting a common resource pool with the maximum PDCCH symbol of 4, and scheduling the resources of the first class of terminals and the second class of terminals according to a preset rule.

In this embodiment, if the resources of the PDCCH symbol being maximum 4 can schedule all the first class terminals, then in order to improve the utilization rate of the resources and ensure that the first class terminals can be scheduled in time, the first class terminals and the second class terminals may be scheduled according to the common terminal resource pool and the preset rule, for example, according to the preset rule, all the first class terminals are scheduled by using the resources of the PDCCH symbol being maximum 4, then some terminals in the second class terminals are scheduled by using the remaining resources, and the remaining terminals in the second class terminals may be scheduled on the next subframe.

It can be understood that the part of the terminals in the second class of terminals may be terminals randomly selected by the network device, or may be determined by the network device according to the priority of the terminal and the priority of the service.

And 68, adopting the SUL resource pool to schedule the resources of the first class terminal according to a preset rule.

In this embodiment, if the resources of the PDCCH symbol being 4 at most cannot schedule all the first class terminals, in order to ensure that all the first class terminals can be scheduled in time, the resource pool of the SUL terminal may be directly utilized to perform resource scheduling on the first class terminals according to a preset rule.

It should be noted that, the specific expression of the preset rule in this embodiment may refer to the description in the embodiment shown in fig. 2, and is not described herein again.

In the embodiment of the application, the network device can flexibly adjust the number of the OFDM of the downlink control channel according to the capability of the terminal, and can select the first-class terminal and the second-class terminal according to a preset rule when the first-class terminal and the second-class terminal need to be scheduled on one subframe, so that the control channel resource of the PDCCH can be maximally utilized, and the problem of insufficient PDCCH resource on a certain subframe can be solved.
