Dynamic scheduling method and device for maximizing scheduling user set potential

Abstract

The invention discloses a dynamic scheduling method and a dynamic scheduling device for maximizing scheduling user set potential, which are used for a scene that a base station carries out selective scheduling when facing large-scale user terminals. Firstly, a feasible user set is obtained through screening according to user signal to interference plus noise ratios and service requirements; then different user subsets are constructed in the feasible user set, and a user subset which meets the service requirements of all users in the set and has the minimum total sending power is found to serve as a scheduled user set; and a user from the scheduled user set is taken out, the remaining user set is taken as a to-be-optimized user set, a to-be-optimized user set with the minimum total sending power is selected, and the taken-out user is recorded. If the last added user in the scheduled user set is the same as the recorded extracted user, outputting the scheduled user set and the corresponding beam forming vector. The method can perform user scheduling and beam forming optimization at the same time, and has the advantages of low time complexity, large number of scheduled users, small interference among the scheduled users and the like.

Description

technical field [0001] The present invention relates to the communication resource allocation problem in the communication scene satisfying the specific rate requirement, and in particular relates to a dynamic scheduling method and device for maximizing the scheduling of user concentration. Background technique [0002] In recent years, with the explosive growth of Internet and Internet of Things application requirements, the contradiction between the limited spectrum resources faced by wireless communications and the continuously growing wireless service requirements has become increasingly prominent. In order to support higher-speed wireless transmission, the fifth-generation (5G) and post-5G mobile communication systems will use high-frequency millimeter-wave communication on the basis of utilizing lower frequency band resources to meet the user's "Quality of Experience (QoE) )” as the center of wireless communication needs. Compared with the fourth generation (4G) mobil...

Problems solved by technology

In the uRLLC scenario, in order to minimize the transmission delay, data with a finite block length (channel usage) is usually sent, so that the traditional Shannon formula assumes the condition (assuming that the code word length of the channel coding and the block length allowed to carry data grow without limit ) cannot satisfy

On the other hand, it is noted that these user scheduling algorithms usually only consider the orthogonality of user channels or maximize the network capacity, but do not specifically consider the specific service requirements of different users, such as minimum rate requirements, reliability requirements, etc.
