Embodiment Construction

[0040] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0041] figure 2 It is a flowchart of a scheduling method for improving RB resource utilization provided by an embodiment of the present invention, as shown in figure 2 shown, including:

[0042] Step S201: When receiving the to-be-sent message of each user terminal UE, determine the total amount of to-be-sent messages of each UE;

[0043] Step S202: According to the determined total amount of packets to be sent of each UE, classify the packets to be sent of all UEs into different scheduling queues with different access periods;

[0044] Step S203: During each packet scheduling, according to the access cycle of each scheduling queue, visit multiple sch...

Abstract

The invention discloses a scheduling method and device for improving the utilization rate of RB resources, which relate to the technical field of wireless communication. The method comprises the following steps: when receiving a to-be-sent message from each piece of user equipment UE, determining the buffer size of the to-be-sent message of each UE; classifying the to-be-sent messages of all the UE to different scheduling queues with different access cycles according to the determined buffer size of the to-be-sent message of each UE; and in each message scheduling, accessing the scheduling queues in turn according to the access cycle of each scheduling queue, and selecting one UE for scheduling from the at least one accessed scheduling queue so that the to-be-sent message of the scheduledUE can make full use of an allocated resource block RB. The possibility that a single TTI (Transmission Time Interval) simultaneously schedules multiples piece of UE with small buffer size is reduced.Therefore, the utilization rate of empty resources and the system throughput are improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a scheduling method and device for improving RB resource utilization. Background technique [0002] Due to the development of the Internet, there are various types of services sent through the wireless system, which results in that the total amount of packets (buffer size) waiting to be sent by each UE is also different. At the same time, the number of UEs scheduled by a single TTI (transmission time interval, transmission time interval) is limited by various reasons, typically (1) insufficient PDCCH (Physical Downlink Control Channel, physical downlink control channel) resources; (2) processor capacity limitation; in this way, if the total amount of packets to be sent by several UEs scheduled by the current TTI is relatively small, it will cause waste of air interface RB (Resource Block, resource block) resources, such as figure 1 shown. Contents of the...
