Dynamic resource allocation method for controlled wireless network system based on POMDP

Abstract

A dynamic resource allocation method for a controlled wireless network system based on POMDP belongs to the field of controlled wireless network and communication resource allocation. According to the dynamic resource allocation method of the present invention, a state transition matrix of the number of users accessing a base station in a cell and a feedback observation matrix are constructed, then a user belief state probability and a transmission rate obtained by the user according to the number of opened antennas of the base station are calculated, thus the number of the opened antennas of the base station and the optimal number of the users accessing the base station when the system achieves the maximum benefit can be determined, thereby achieving optimal resource allocation in the cell. The dynamic resource allocation method of the present invention determines the final number of the opened antennas of the base station and the final number of the users accessing the base station by aiming to achieve the maximum system benefit respectively with the maximum user reception power and the minimum user data transmission error rate in the cell in the case that there are the plurality of users and one multi-antenna base station in the cell. The dynamic resource allocation method of the present invention overcomes the problems of excessive energy consumption, large load of the base station in the cell, unmatched number of the opened antennas and the number of the users accessing the base station, and so on, and has certain advantages in the aspects of improving the user reception power, anti-interference performance, and system overall benefit.

Description

technical field [0001] The invention relates to a dynamic resource allocation method of a controlled wireless communication network system based on a partially observable Markov decision process (POMDP). Through the POMDP method, a selection scheme that is beneficial to the resource allocation of the wireless communication network is designed, which belongs to the subject Controlled wireless network and communication resource allocation research related fields. Background technique [0002] Mobile communication has developed rapidly in recent decades, and users' demand for wireless communication network service quality is also constantly improving, prompting the wireless communication system to evolve from 2G, 3G, B3G, 4G and 5G, and the main body of the network will also be dominated by voice. The network is transforming to a network dominated by high-speed data. At the same time, mobile multimedia services have higher and higher requirements on bandwidth, and "broadband" ...
