Abstract

The present invention proposes a method for dynamic resource allocation in a millimeter wave system, which includes initializing system parameters related to dynamic scenarios; observing channel status in a dynamic environment, status of base station beam and user connection status, and power allocation status; judging the current status Whether the actions taken below meet the constraints in the optimization problem; set different income values ​​according to whether the constraints are satisfied; store the data in the experience pool; train the Eval-Net Q network; update the Target-Net Q network; randomly generate The numerical value is compared with the exploration probability; and then the base station beam and user connection status, user power allocation status and exploration probability are updated; after a period of training and learning until convergence, the final base station beam and user connection status and user power allocation status are output. The method solves the technical problem in the prior art that beams and power cannot be jointly allocated in a dynamic channel environment to realize dynamic resource allocation and long-term user fairness.

Description

technical field [0001] The present invention relates to the technical field of mobile communication technology, in particular to a method for dynamic resource allocation in a millimeter wave system. Background technique [0002] At present, the operating frequencies of mobile communication systems are mainly concentrated in the microwave frequency band of 700MHz-2.6GHz, and the shortage of spectrum resources is becoming more and more serious. The millimeter wave communication greatly enriches the spectrum resources by operating in the 30GHz-300GHz frequency band. However, due to the disadvantages of poor penetration, easy absorption, and fast attenuation of millimeter-wave signals, millimeter-wave communication systems have problems such as large signal path loss and small base station coverage. Large-scale antenna technology can improve system capacity, spectrum efficiency, system anti-interference ability and other advantages by configuring a large number of antennas (mor...
