Abstract

The invention discloses a radio resource scheduling method of queue service with finite length. The method comprises the following steps of: calculating the time information of each user data packet in a packet queue composed of user data packets of a radio channel transmission system; respectively calculating the scheduling priority factor of each user data packet according to the time information of each user data packet and the channel condition of user data packet corresponding to user equipment; and selecting the user data packet with a highest scheduling priority factor to schedule according to the calculated magnitude sequence of scheduling priority factors of user data packets. By using the method in the invention, the radio channel resource can be utilized fully.

Description

technical field [0001] The invention relates to the communication field, in particular to a wireless resource scheduling method for limited-length queue services. Background technique [0002] In a data transmission system, a typical transmission mode is packet transmission, that is, user data arrives at the system in the form of data packets and is stored in a queue, and the system calls transmission resources to process and transmit data to each user. Aiming at services with queues of limited length, many resource scheduling methods have been researched and adopted at present. Specifically, the wireless channel transmission system can be divided into two categories: a method for scheduling according to user queue status and a method for scheduling according to user channel status. [0003] figure 1 It is a schematic diagram of a wireless transmission system with a finite length queue. The scheduling period is a time frame, that is, each fixed time segment is a frame. In ...
