Embodiment Construction

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0053] In order to make full use of PRB resources and improve system throughput and user perception, in the embodiment of the present invention, the scheduling priority of each current UE to be scheduled is obtained according to the preset MAC scheduling algorithm, and the number of current UEs to be scheduled is determined to be greater than N , the first N-1 UEs are scheduled sequentially according to the scheduling priority, and then the best...

Abstract

The present invention relates to the field of communications, and in particular to a method and device for resource scheduling. The method is to obtain the scheduling priority of each current UE to be scheduled according to a preset MAC scheduling algorithm, and determine that the number of UEs currently to be scheduled is greater than N , the first N-1 UEs are scheduled sequentially according to the scheduling priority, and then the best UE is determined from every other UE to be scheduled except the first N-1 UEs as the current Nth UE to be scheduled. Among them, N represents the maximum number of UEs that can be scheduled in one subframe. In this way, the MAC scheduling algorithm and the processing performance of eNodeB, that is, the limit on the maximum number of UEs that can be scheduled in one subframe, are combined to maximize the PRB resource utilization or PRB resource utilization. Maximum performance, improving system throughput and user perception.

Description

technical field [0001] The present invention relates to the communication field, in particular to a resource scheduling method and device. Background technique [0002] In the Long Term Evolution (LTE) wireless communication network, the Physical Resource Block (PRB) resource is one of the most precious wireless resources. The LTE system adopts a shared channel mechanism. In order to use and Allocating shared resources requires scheduling between different user terminals (User Equipment, UEs) or between data radio bearers (Data Radio Bearers, DRBs) of different UEs. Allocate and reclaim resources. How to make full use of limited PRB resources (for example, 20M bandwidth corresponds to 100 PRB resources) directly determines the throughput of the system and the quality of user perception. However, under the existing technology, due to the limitation of the system processing capacity, that is, the number of users scheduled per subframe and the difference in the amount of data...
