Problems solved by technology

[0020] However, among the above traditional algorithms, except for the FLS algorithm, the relationship between QoS delay and queuing delay is not considered. Although the FLS algorithm considers the amount of data to be transmitted in the frame, it does not consider the amount of data to be transmitted within the transmission time interval (Transmission TimeInterval, TTI). transfer data size

Abstract

The invention discloses a 5G wireless resource scheduling method and a downlink scheduling system, and belongs to the technical field of wireless communication. The method comprises the following steps: calculating the data volume needing to be transmitted in the f-th system frame of each arrival real-time stream by utilizing a discrete control system theory; calculating the priority of the real-time stream in each transmission time period; judging whether residual RB resources exist or not, and if not, ending the scheduling; if the remaining RB resources exist, calculating the priority of each transmission time period of the non-real-time stream; and after one-time scheduling is finished, the MAC layer data queue is emptied, and wireless resource scheduling is completed. According to the invention, for time-sensitive services, the packet loss rate of network transmission of the service type can be reduced, so that the time delay of the service type is further reduced.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular, to a 5G communication wireless resource scheduling method and a downlink scheduling system. Background technique [0002] The goal of radio resource scheduling is to manage and allocate air interface radio resources to provide uplink and downlink data transmission services for terminals. As one of the core functions of the MAC layer, radio resource scheduling realizes the dynamic allocation of time-frequency resources. In the 5G mobile communication system, the scheduling of uplink and downlink is separate, and the scheduling result depends on the scheduling strategy adopted by the uplink and downlink scheduler on the 5G base station side. The general scheduling process of the scheduler is as follows figure 1 shown. [0003] It can be seen that the input parameters of the scheduler mainly include: [0004] a. HARQACK / NACK information fed back by the U...
