Description

A resource scheduling method and device

technical field

Embodiments of the present invention relate to the field of communication technologies, and in particular, to a resource scheduling method and device.

Background technique

Narrow Band Internet of Things (NB-IoT) is built on cellular networks and consumes only about 180KHz frequency band. It can be directly deployed in GSM networks, UMTS networks or LTE networks to reduce deployment costs and achieve smooth upgrades. NB-IoT has low cost, low power consumption, wide coverage, and the ability to support massive connections. It is mainly for low-cost, low-power, low-speed, and wide-coverage IoT services, such as sensors, meter reading, logistics monitoring, Tracking classes etc.

NB-IoT defines three different coverage levels. User equipment with a high coverage level improves its coverage by repeated repetitions, which is 20dB larger than the traditional coverage. Under the same frequency band, the coverage area is expanded by 100 times. In the coverage enhancement scenario, the transmission of Narrowband physical downlink control channel (NPDCCH) and narrowband physical downlink shared channel (Narrowband physical downlink shared channel, NPDSCH) needs to be repeated multiple times. The duration reaches the second level. There is a certain fixed delay between NPDCCH, NPDSCH, and Narrowband Physical Uplink Shared Channel (NPUSCH) in the process of simultaneous uplink and downlink services, and resource fragments are likely to occur during the continuous process of multi-user scheduling, resulting in resource fragmentation. The waste and users of different levels are blocked due to the limited scheduling resources.

Detailed ways

In order to make the object, technical solution and beneficial effects of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

FIG. 1 is a schematic diagram of a system architecture provided by an embodiment of the present invention.

As shown in FIG. 1, the system architecture includes a base station 101, a terminal 102, and a terminal 103. The system also includes a resource scheduling device (not shown in FIG. 1) for executing a resource scheduling method. The resource scheduling device may be An independent device in the base station may also be a functional module or functional unit integrated in the base station. The base station 101 and the terminal 102, and the base station 101 and the terminal 103 are connected through wireless. The base station schedules uplink and downlink resources for the terminal 102 and the terminal 103 .

Any one of the terminal 103 and the terminal 104 may communicate with one or more core networks via a radio access network (Radio Access Network, RAN for short), and the terminal may refer to a user equipment (User Equipment, UE for short), an access terminal , subscriber unit, subscriber station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device. The access terminal may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), Handheld devices with wireless communication capabilities, computing devices or other processing devices connected to wireless modems, in-vehicle devices, wearable devices, etc.

Based on the system architecture in FIG. 1 , FIG. 2 exemplarily shows a schematic diagram of downlink resource scheduling and feedback timing provided by an embodiment of the present invention.

The downlink resource scheduling process includes searching for downlink NPDCCH resources, NPDSCH resources and ACK/NACK feedback resources, wherein NPDCCH resources and NPDSCH resources are allocated from downlink resources, and ACK/NACK feedback resources are allocated from uplink resources. As shown in FIG. 2 , NPDCCH resources for sending downlink control information (Downlink Control Information, DCI) information are allocated in downlink (DL) resources, and the DCI information indicates NPDSCH resources for sending downlink data. Then, after the end subframe of the NPDCCH resource is determined, corresponding NPDSCH resource and ACK/NACK feedback resource start to be allocated. As shown in FIG. 2 , the end subframe n of the NPDCCH resource and the sending subframe of the NPDSCH resource are n+5+k ₀ , where k ₀ is the time delay between the NPDSCH resource and the NPDCCH resource. The sending subframe of the ACK/NACK feedback resource is n+k ₀ -1, where k ₁ is the delay of the ACK/NACK feedback resource corresponding to the NPDSCH resource.

Based on the system architecture in FIG. 1 , FIG. 3 exemplarily shows a schematic diagram of uplink resource scheduling and feedback timing provided by an embodiment of the present invention.

The uplink resource scheduling process includes allocating NPDCCH resources and NPUSCH resources for sending DCIN0, wherein the NPDCCH resources are allocated from the downlink resources, and the NPUSCH resources are allocated from the uplink resources. As shown in FIG. 3 , it is first necessary to allocate NPDCCH resources for sending DCIN0 (end subframe n), and DCI N0 information indicates NPUSCH resources for sending uplink data. Then, corresponding uplink resource allocation starts at n+k ₂ , that is, NPUSCH resource allocation, where k ₂ is the time delay between NPDSCH resource and NPDCCH resource.

According to Figure 2 and Figure 3, it can be seen that in both the uplink scheduling and downlink scheduling processes, downlink NPDCCH resources are required, where the downlink NPDCCH resources required in the uplink scheduling process are used to schedule uplink data transmission, and the downlink Downlink NPDCCH resources are used to schedule downlink data transmission. In the downlink scheduling process, a certain resource interval will be generated between NPDCCH and NPDSCH every time. In the case of multi-user scheduling, it will inevitably lead to resource discretization and fragmentation increase, thereby affecting multi-UE in-depth scheduling and resource utilization.

Based on the above-mentioned FIG. 1 , FIG. 2 and FIG. 3 , the resource scheduling method provided by the embodiment of the present invention will be described in detail below.

Fig. 4 exemplarily shows a schematic flowchart of a resource scheduling method provided by an embodiment of the present invention. The resource scheduling method is executed by a resource scheduling device, as shown in Figure 4, the method includes the following steps:

Step 401: Obtain resource allocation information of downlink resources; the resource allocation information is used to determine whether downlink resources are occupied;

Step 402: Determine whether there is a hole resource in the downlink resource according to the resource allocation information;

Step 403: If there are empty resources in the downlink resources, allocate narrowband physical downlink control channel NPDCCH resources to the UE to be scheduled according to the empty resources; the empty resources indicate unoccupied and continuous radio bearer RBs ; Hole resources indicate unoccupied and continuous radio bearer RB; the first preset condition includes that there is an uplink data transmission requirement, and the number of RBs required for bearing and scheduling uplink data transmission downlink control information DCI is less than or equal to the hole resource and the RB position indicated by the hole resource is within the current search space of the UE to be scheduled. In the embodiment of the present invention, RB is a downlink subframe resource.

Among them, the search space is a user-level parameter with periodicity, and the search space also corresponds to different repetition levels and aggregation levels. The search spaces corresponding to each UE to be scheduled may be the same or different.

In the embodiment of the present invention, the resource scheduling device acquires resource allocation information of downlink resources, and the resource allocation information is used to determine whether the downlink resources are occupied; determine whether there are empty resources in the downlink resources according to the resource allocation information; if there are empty resources in the downlink resources, then Allocate narrowband physical downlink control channel NPDCCH resources according to the user equipment UE to be scheduled that is determined to meet the first preset condition in the hole resource; wherein, the hole resource indicates an unoccupied and continuous radio bearer RB; the first preset condition includes existence Uplink data transmission requirements, and the number of RBs required for carrying downlink control information DCI for scheduling uplink data transmission is less than or equal to the number of RBs in the hole resource, and the RB position indicated by the hole resource is within the current search space of the UE to be scheduled. In this way, allocating NPDCCH resources to UEs to be scheduled with uplink data transmission requirements according to the hole resources can reduce resource fragmentation, thereby improving resource utilization and reducing resource waste.

In specific implementation, step 401 is implemented by the following manner: initializing uplink and downlink resources and scheduling parameters. According to the cell configuration information, including broadcast and common channel configuration information, calculate the current cell fixed resource usage, and fixedly map the information to the uplink time-frequency resource list and downlink time-frequency resource list. Then, when it is necessary to determine the resource allocation information of the downlink resources, the occupancy of the downlink resources can be determined according to the downlink time-frequency resource list.

When entering the current scheduling cycle, unoccupied RB resources are obtained first, and the uplink and downlink resources are allocated to each UE to be scheduled in combination with the currently received resource requirements of each UE to be scheduled. Specifically, before scheduling, the number of scheduling resources used by each UE to be scheduled for sending DCI and the search space information of the NPDCCH resources of the UE to be scheduled may be estimated. Since the search space corresponding to each UE to be scheduled may be different, when scheduling the NPDCCH resource for sending DCI for the UE to be scheduled, it is necessary to determine whether the RB resource is within the search space of the UE to be scheduled. If not, Then the RB resource cannot be used as the NPDCCH resource for sending DCI; if it is in the search space, the RB resource can be considered as the NPDCCH resource for sending DCI.

In an optional implementation manner, determining whether there is a hole resource in the downlink resource includes the following implementation manner: according to the resource allocation information, determine at least one group of unoccupied continuous RBs from the downlink resource; For each group of unoccupied continuous RBs, perform: if the number of unoccupied continuous RBs in this group is less than the preset RB quantity threshold and greater than the DCI required by each UE to be scheduled for carrying and scheduling uplink data transmission with uplink data transmission requirements If the minimum value of the number of RBs is the minimum value, it is determined that the group of unoccupied continuous RBs are empty resources. If the number of unoccupied continuous RBs in the group is greater than the preset RB quantity threshold, or the number of unoccupied continuous RBs in the group is greater than the DCI required by each UE to be scheduled for carrying and scheduling uplink data transmission with uplink data transmission requirements If the minimum value of the number of RBs is the minimum value, it is determined that the unoccupied continuous RBs in this group are not empty resources. In this way, each set of determined hole resources can satisfy the number of RBs required by at least one UE to be scheduled.

For example, there are 4 UEs to be scheduled that have uplink data transmission requirements, and the number of RBs required by each UE to be scheduled to carry the DCI for scheduling uplink data transmission is: UE ₁ needs 4 RBs, UE ₂ needs 4 RBs. 4 RBs, UE ₃ needs 8 RBs, and UE ₄ needs 16 RBs. It can be seen that the minimum number of RBs required by each UE to be scheduled for carrying DCI for scheduling uplink data transmission is 4.

For example, the preset threshold for the number of RBs is 10, the number of unoccupied continuous RBs in the first group is 3, and the number of unoccupied continuous RBs in the second group is 8. It can be seen that the number of unoccupied continuous RBs in the first group 3 is less than the preset RB quantity threshold 10, but less than the minimum value 4 of the RB quantity required by each UE to be scheduled, therefore, the first group of unoccupied continuous RBs is not a hole resource; the second group of unoccupied continuous RBs is 8 It is less than the preset RB quantity threshold of 10 and greater than the minimum value of 4 for the RB quantity required by each UE to be scheduled. Therefore, the second group of unoccupied continuous RBs are empty resources.

Further, in the above step 402, the determined hole resources may have multiple UEs that can be used as UEs to be scheduled. In order to allocate resources reasonably and maximize the utilization of hole resources, an optional implementation mode is provided as follows: The first preset condition further includes: the UE to be scheduled is the UE with the smallest difference between the number of RBs required to carry the DCI for scheduling uplink data transmission and the number of RBs of the hole resources among the UEs with uplink data transmission requirements .

That is to say, after the hole resources are determined, if there are multiple RBs that meet the requirements for uplink data transmission and are used to carry the downlink control information DCI for scheduling uplink data transmission, the number of RBs required is less than or equal to the number of RBs in the hole resources , and the RB position indicated by the hole resource is within the current search space of the UE to be scheduled, the number of RBs required for carrying the downlink control information DCI for scheduling uplink data transmission in these multiple UEs is the same as The UE with the smallest difference in the number of RBs in the hole resources is the UE to be scheduled. In this way, the hole resources are allocated to the waiting group with the smallest difference between the number of RBs required for carrying the downlink control information DCI for scheduling uplink data transmission and the number of RBs in the hole resources. The UE is scheduled so that the hole resources are occupied as much as possible and there are as few unoccupied RBs as possible, thereby maximizing resource utilization and avoiding resource waste.

Further, after step 402, the method further includes: if it is determined that there is no hole resource in the downlink resources, allocating NPDCCH resources and NPDSCH resources from the downlink resources to UEs to be scheduled that have downlink data transmission requirements.

In the embodiment of the present invention, after the empty resource is searched, it further includes: updating the resource allocation information of the downlink resource to obtain the updated resource allocation information; the updated resource allocation information indicates that all the downlink resources are occupied and unoccupied Resources. If it is determined that the updated resource allocation information satisfies a second preset condition, then end the current scheduling; the second preset condition includes that the total amount of downlink resources allocated by the downlink resource reaches a preset total threshold, or, within the specified The number of UEs to be scheduled to which resources have been allocated in the current scheduling period reaches a preset number threshold. In this way, resources can be reasonably allocated in each scheduling period, and resource utilization can be improved.

In a specific implementation, a scheduling threshold may be set for each scheduling period. On the one hand, the total number of UEs to be scheduled with a demand for uplink data transmission and the number of UEs to be scheduled with a demand for downlink data transmission is set, that is, a preset number threshold. On the other hand, the total amount of downlink resource allocation is set, that is, the preset total amount threshold. The scheduling threshold can be set according to actual needs.

In combination with the above embodiments, at the current scheduling time, according to the unoccupied resources in the current system, the number of RBs required by the UE to be scheduled, and combined with the search results of empty resources, the scheduling sequence is as follows:

First, search whether there are hole resources in the downlink scheduling space. If there is, the uplink scheduling process is prioritized, the UE to be scheduled is extracted from the uplink request list, and the RB hole resources are allocated to the NPDCCH required by the UE to be scheduled. Full hole position, while considering that the uplink NPDSCH resource satisfies the adapted scheduling relationship. If not, the downlink scheduling process is prioritized to schedule NPDCCH resources and NPDSCH resources, and the scheduled NPDCCH and NPDSCH satisfy the (n+5+k ₀ ) timing relationship. After that, record the scheduling order at this time and update the allocated resources to the resource allocation information, and record the total number of currently allocated uplink and downlink resources and the total amount of allocated downlink resources. If the total amount of downlink resources allocated by the downlink resources reaches the preset total amount threshold, or the number of UEs to be scheduled whose resources are allocated in the current scheduling period reaches the preset number threshold, the current scheduling period ends. In this way, the uplink and downlink scheduling sequence can be reasonably arranged, and the interval resource for downlink scheduling is allocated to the DCI for uplink scheduling, thereby improving the efficiency of multi-UE scheduling and reducing the operation of UE blind search resources.

In order to more clearly introduce the resource scheduling method in the embodiment of the present invention, the following examples are provided.

Fig. 5 exemplarily shows a schematic flowchart of another resource scheduling method provided by an embodiment of the present invention. The resource scheduling method is executed by a resource scheduling device, as shown in Figure 5, the method includes the following steps:

Step 501: Initialize uplink and downlink resources and scheduling parameters;

Step 502: Obtain the scheduling request at the current scheduling moment;

Step 503: Obtain the list of uplink and downlink resources at the current scheduling moment according to the scheduling request;

Step 504: Whether there are empty resources in the current downlink resource; if yes, execute step 505; if not, execute step 506;

Step 505: Select UEs to be scheduled that have uplink data transmission requirements for scheduling allocation; after that, execute step 507;

Step 506: Select UEs to be scheduled that have uplink data transmission requirements for scheduling allocation; then, execute step 507;

Step 507: Whether the scheduling threshold is reached; if so, execute step 508; if not, execute step 504;

Step 508: This scheduling ends.

It can be seen from the above-mentioned embodiments that, according to the current system business conditions and the utilization of uplink and downlink resources, it is judged whether the latest downlink scheduling space leaves spaced available hole resources, and if so, the uplink UEs to be scheduled are screened from the uplink list, and the Segment hole resources are allocated to uplink UEs to be scheduled; otherwise, downlink UEs to be scheduled are screened from the downlink list. After downlink scheduling is performed and hole resources are generated between DCI and NPDSCH, the segment resources are preferentially used as DCI resources for uplink scheduling for uplink indexing. allocation, so as to achieve the optimal utilization of scheduling resources.
