Wireless resource allocation method in imperfect channel state information fading channel

Abstract

The invention discloses a wireless resource allocation method in an imperfect channel state information fading channel, and the method comprises the following steps: (1) considering the influence of achannel estimation error, and modeling the estimation error of channel state information into an uncertain set by using an ellipsoid approximation method; (2) establishing a joint optimization problem by using a weighted summation method; (3) based on an on-line learning method, respectively proposing a time delay sensitive data scheduling method aiming at two conditions of channel estimation error boundary determination and uncertainty. The scheduling algorithm based on online learning provided by the invention can solve the problem of channel state information estimation errors, and improves the performance of the system in the aspects of energy efficiency, transmission delay and packet loss rate.

Description

technical field

[0001] The invention belongs to the technical field of wireless communication, and relates to a wireless resource allocation method in an imperfect channel state information fading channel. Background technique

[0002] With the popularization of wireless services, the demand for wireless transmission has increased significantly in recent years. In order to meet this demand, the future cellular mobile communication will provide a peak transmission rate exceeding 10Gb per second. However, high throughput usually means high energy consumption. The total energy consumption of wireless communication infrastructure accounts for more than 3% of the total electricity consumption worldwide, and this proportion is expected to increase rapidly as the data transmission rate of wireless communication increases in the future. The increase of energy consumption and the direct increase of greenhouse gas emissions have been considered as a major threat to environmental pro...
