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 invention relates to the field of communication, and in particular relates to a resource scheduling method and device. The method comprises the steps of: according to a pre-set MAC scheduling algorithm, obtaining the scheduling priority of current each UE to be scheduled, when the fact that the number of current UE to be scheduled is greater than N is determined, sequentially scheduling previous N-1 UE according to the scheduling priority, then, determining the best UE from other UE to be scheduled, except the previous N-1 UE, and taking the best UE as the current Nth UE to be scheduled, wherein N represents the maximum number of UE capable of being scheduled by one sub-frame. Thereby, the MAC scheduling algorithm is combined with the eNodeB processing performance, namely limitation of the maximum number of the UE capable of being scheduled by one sub-frame; therefore, the PRB resource utilization rate is maximum; or, the PRB resource efficiency is maximum; and the system throughput and the user perception are improved.

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 (Long Term Evolution, LTE) wireless communication network, the physical resource block (Physical Resource Block, PRB) resource is one of the most precious wireless resources, the LTE system adopts the mechanism of shared channel, in order to use To allocate and share resources, scheduling needs to be performed between different user equipments (User Equipment, UEs) or between data radio bearers (Data Radio Bearers, DRBs) of different UEs. The main purpose of scheduling is to provide packet data for the user plane and control plane 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 t...
