Embodiment
Express clearly clear for making the object, technical solutions and advantages of the present invention, below in conjunction with drawings and the specific embodiments, the present invention is further described in more detail.
In embodiments of the present invention, the user that priority is the highest is being selected to be the first dispatched users according in the dispatched users queue of priority arrangement, and then determine the second dispatched users, be that two users carry out Resourse Distribute, and record secondary pairing user and the remaining resource of secondary pairing user, when system does not have idling-resource, also utilize the remaining resource of secondary pairing user, for correspondingly matching user resource allocation.Above method can be avoided complicated resource lookup process and ensure that dispatching priority of users order is unaffected, thus ensures systematic function.
See the method flow schematic diagram that accompanying drawing 1 is Resourse Distribute, specifically comprise the following steps:
101, in dispatched users queue, the user that priority is the highest is selected to be the first dispatched users.
According to priority formula f (CQI, BSR), according to priority, order arrangement user from high to low obtains dispatched users queue.According to User Priority order from high to low, in dispatched users queue, the user that priority is the highest is selected to be the first dispatched users.After the first selected dispatched users completes scheduling, upgrade dispatched users queue, select in dispatched users queue user that current priority is the highest as on once the first dispatched users.
102, judge system whether idling-resource, if the available free resource of system, then perform 103; If system does not have idling-resource, then perform 107.
103, the available free scheduling of resource of system, determines the second dispatched users in the pairing user of the first dispatched users.
The available free scheduling of resource of system, because the first dispatched users has at least one pairing user, then needs from multiple pairing user, determine that a pairing user is as the second dispatched users.
First, by channel quality and user's data to be transmitted amount determination user utility value.Channel quality and user's data to be transmitted amount are the relations be directly proportional to user utility value.Can carry out detailed setting according to concrete system, the present invention does not limit this.
Pairing user corresponding to maximum user utility value is the second dispatched users.Because priority is relevant to user utility value, ensure that pairing user corresponding to maximum user utility value becomes the second dispatched users, just can ensure that the priority according to user carries out the scheduling of resource.
104, in the first dispatched users and the second dispatched users, first resource user and Secondary resource user is determined by the data to be transferred amount of user.
The data to be transmitted amount of the first dispatched users is different from the data to be transmitted amount of the second dispatched users, then select user that wherein data to be transmitted amount is larger as first resource user, and the less user of data to be transmitted amount is as Secondary resource user.
Specifically, the data to be transferred amount of the first dispatched users is more than or equal to the data to be transferred amount of the second dispatched users, then the first dispatched users is first resource user, and the second dispatched users is Secondary resource user.
The data to be transferred amount of the first dispatched users is less than the data to be transferred amount of the second dispatched users, then the first dispatched users is Secondary resource user, and the second dispatched users is first resource user.
105, being first resource user resource allocation, in the resource that first resource user distributes, is Secondary resource user resource allocation, and mark first resource user matches user recording in institute's Resources allocation not by the surplus resources of Secondary resource CU for secondary.
Determining that the object of first resource user is, is the first resource user resource allocation that data to be transmitted amount is larger, then in the resource of first resource user distribution, is Secondary resource user resource allocation.If the data to be transmitted amount of first resource user is less than the data to be transmitted amount of Secondary resource user, then cannot realize above-mentioned technical scheme.
Data to be transmitted amount due to first resource user is greater than the data to be transmitted amount of Secondary resource user, that is first resource user distribute resource in not completely shared by Secondary resource user, also has remaining resource, mark first resource user matches user recording in institute's Resources allocation not by the surplus resources of Secondary resource CU for secondary, like this when system does not have idling-resource, the surplus resources of first resource user can also be utilized to carry out secondary pairing.
106, upgrade system resource and dispatched users queue, namely in dispatched users queue, delete first resource user and Secondary resource user, again in dispatched users queue, select the first dispatched users.
Upgrade system resource, in dispatched users queue, again select user that current priority is the highest as the first dispatched users.
107, when system does not have idling-resource, then secondary pairing is carried out.
Namely there is the pairing user not yet dispatched in secondary pairing user; On the surplus resources of secondary pairing user, it is the pairing user resource allocation not yet dispatched.If there is multiple pairing user not yet dispatched, be then pairing user resource allocation corresponding to maximum user utility value.
