Embodiment Construction

[0049] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0050] There are certain defects in the existing LTE uplink and downlink scheduling devices and methods:

[0051] Round Robin: This algorithm can bring opportunity fairness, but the device throughput is the lowest; Maximum C / I algorithm (Max C / I): The advantage of this algorithm is that it can maximize the device throughput, but if the user's If ...

Abstract

The embodiment of the invention provides an uplink and downlink scheduling method and device based on user perception. The method comprises the following steps: obtaining available scheduling resources in a scheduling period TTI of each scheduling; removing the UE without the to-be-sent data in the current scheduling queue; updating a TA regulation factor for activating the UE; acquiring the priority of the UE to be scheduled at this time, and performing scheduling queue arrangement from high to low according to the priority; and scheduling the UE in sequence according to the priority of the scheduling queue, and calling the data in the UE cache according to the size of the currently available scheduling resource and the power capability of the UE. According to the embodiment of the invention, the defect of low throughput or non-uniform resource allocation of the device in the existing packet scheduling algorithm is overcome.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of LTE wireless networks, and in particular to a method and device for uplink and downlink scheduling based on user perception. Background technique [0002] The present invention relates to the technical field of LTE wireless network. The English full name of LTE is Long Term Evolution, that is, the long-term evolution of universal mobile communication technology. Packet scheduling is to manage and schedule the services of packet data users according to the above-mentioned characteristics of packet data services. It determines when to initiate packet transmission and the available bit rate. [0003] There are three classic packet scheduling algorithms in LTE device design: 1. Round Robin: eNodeB schedules each user at an equal time interval, and each user gets an equal scheduling opportunity. 2. Maximum carrier-to-interference ratio algorithm (MaxC / I): eNodeB estimates the channel qu...
