Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] Such as figure 1 The illustrated embodiment is that the embodiment is a throughput-first LTE fair scheduling method, including N users {u 1 , u 2 ,...,u N}, set u i is each user, u i ∈{u 1 , u 2 ,...,u N};

[0034] Step 1: Throughput accounting;

[0035] Step 1-1: Set the signal-to-noise ratio of each user as The bit error rate of the business The number of RB resource blocks allocated to each user is use the formula Compute the throughput evaluation metric for each user

[0036] Step 1-2: Set the bandwidth occupied by each RB resource to B RB , using the formula Calculate throughput per user

[0037] Step 2: Priority update;

[0038] Step 2-1: Using the formula Calculate throughput expectations and using the formula Calculate the dimensionless throughput value for each user

[0039] Step 2-2: Utilize t...

Abstract

The invention discloses a LTE fair scheduling method with throughput priority, comprising the following steps: throughput calculation; priority update; high-throughput user scheduling and low-throughput user scheduling. The invention can automatically track the rate change of each user in the cell, dynamically set the evaluation threshold, screen out users with good channel quality, and improve their scheduling priority; for users with low throughput, fair scheduling is used to prevent their Starvation, and then take into account the system throughput and fairness at the same time, improve the service quality of business development to ensure the characteristics of customer perception.

Description

technical field [0001] The invention relates to a dispatching method of an LTE system, in particular to a throughput-priority LTE fair dispatching method. Background technique [0002] LTE adopts various key technologies such as OFDM, SC-FDMA and MIMO to improve and enhance the air interface technology of 3G, which can significantly reduce the delay of the user plane and the control plane, and improve the throughput of the cell. How to better use the scheduling algorithm is the key point to improve throughput. For different users, RB resource allocation is performed according to various factors such as their current channel indication, service quality, and scheduling status, so as to ensure that the allocated resources are fully utilized each time. , to enhance user perception. Constrained by the limited spectrum resources, the resource scheduling algorithm of LTE is very important, which determines the sequence of packet transmission and the available transmission rate. ...
