All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "comprises" and "comprising," and any variations thereof, in the description and claims of this invention, are intended to cover non-exclusive inclusions, e.g., a process or an apparatus that comprises a list of steps is not necessarily limited to those structures or steps expressly listed but may include other steps or structures not expressly listed or inherent to such process or apparatus.
The embodiment of the invention provides a method for scheduling radio resources, which can be executed by a scheduling device of radio resources, and the scheduling device can be arranged in a base station. Referring to fig. 1, fig. 1 is a flowchart of a method for scheduling radio resources according to an embodiment of the present invention, and as shown in fig. 1, the method includes:
And 102, if the RB utilization rate is higher than a preset threshold value, reducing the SPS resource configuration proportion of the cell.

Optionally, the target priority service in this embodiment includes, but is not limited to, CBTC service and service with priority higher than that of the CBTC service, for example, service with Qos Class Indication (QCI) equal to 5 and data retransmission service.
In this embodiment, the scheduling apparatus obtains the RB utilization rate of the target priority service of the cell in the current period according to a preset period.
Optionally, this embodiment may respectively calculate an RB utilization rate of an uplink target priority service and an RB utilization rate of a downlink target priority service in the cell, and configure the uplink and downlink SPS resources of the cell based on the calculated RB utilization rates, or may only calculate the RB utilization rate of the uplink or downlink target priority service in the cell, and configure the uplink or downlink SPS resources based on the calculated uplink or downlink RB utilization rates, for example, when the RB utilization rate of the uplink target priority service in the cell in the current period is lower than a first preset threshold, increase the resource configuration ratio of the uplink SPS resource in the cell, when the RB utilization rate of the downlink target priority service in the cell in the current period is lower than a second preset threshold, increase the resource configuration ratio of the downlink SPS resource in the cell, otherwise, when the RB utilization rate of the uplink target priority service in the cell in the current period is higher than the first preset threshold, the SPS resource allocation ratio of the uplink in the cell is reduced to ensure the priority of the target priority service of the uplink, and similarly, the downlink direction is also the same, that is, what can be exemplified here is to reduce the SPS resource allocation ratio of the cell when the RB utilization ratio of the target priority service in the cell is higher than a preset threshold, and increase the SPS resource allocation ratio of the cell when the RB utilization ratio of the target priority service in the cell is lower than the preset threshold.
Optionally, in this embodiment, when the SPS resource configuration ratio of the uplink or downlink of the cell is adjusted based on the RB utilization ratio of the uplink or downlink target priority service in the cell, the adjustment range may be set as needed, for example, the adjustment range of the SPS resource configuration ratio may be set according to different values of the preset threshold (the first preset threshold or the second preset threshold) used for comparison, when the value of the preset threshold is smaller, the adjustment range of the SPS resource configuration ratio is set to be larger, and when the value of the preset threshold is larger, the adjustment range of the SPS resource configuration ratio is set to be smaller. Of course, this is only an example and is not the only limitation of the present invention, in practice, multiple thresholds may also be set in an actual scenario, for example, thresholds a and b may be set, where a is smaller than b, when the calculated RB utilization is smaller than a, the SPS resource allocation ratio is adjusted based on the preset adjustment range smaller than a, when the RB utilization is larger than a is smaller than b, the SPS resource allocation ratio is adjusted based on the preset adjustment range larger than a and smaller than b, and when the RB utilization is larger than b, the SPS resource allocation ratio is adjusted based on the preset adjustment range larger than b.

Optionally, in a first possible manner, the number of RBs used by the target priority service that is uplink in the current period of the cell may be divided by the number of RBs used by all uplink services in the current period of the cell, so as to obtain the RB utilization rate of the target priority service that is uplink in the current period of the cell. The number of RBs used by the target downlink priority service in the current period of the cell is divided by the number of RBs used by all downlink services in the current period of the cell, so as to obtain the RB utilization rate of the target downlink priority service in the current period of the cell, that is, the RB utilization rate called in step 101 in this implementation is a statistical value calculated by using a statistical algorithm.
Optionally, in a second possible manner, after obtaining the statistical value of the RB utilization rate of the target priority service that the cell is uplink in the current period by using the first manner, the statistical average value H of the RB utilization rate of the target priority service that the cell is uplink in the current period may be calculated based on the following expressionnFurther, whether to increase the SPS resource allocation ratio of the cell is determined based on the calculated statistical average of the RB utilization, that is, the RB utilization referred to in step 101 in this implementation is based on the first RB utilizationThe implementation calculates a statistical average value obtained by calculating the obtained statistical value:
Hn=a*R+(1-a)*Hn-1
wherein a is a preset weight value, and a specific value thereof may be set as required, and in this embodiment, a is equal to 0.1 as an example. HnIs a statistical average of the RB utilization of the current cycle, Hn-1The RB utilization rate is the statistical average value of the RB utilization rate of the previous period, and R is the statistical value of the RB utilization rate calculated and obtained in the current period.
In a second possible implementation manner, the algorithm of the statistical average of the utilization rate of the RBs in the cell downlink is the same as that in the uplink, and is not described herein again.
