[0054]This embodiment provides a network resource scheduling method, which is mainly oriented to 6G mobile communication networks. For the NOMA multi-user system in the terahertz frequency band, a novel joint resource scheduling mechanism is proposed, which decouples the joint resource allocation problem into sub-channel allocation. and power allocation two sub-problems, using the improved whale optimization algorithm WOA to solve the approximate optimal solution of the problem in order to achieve green energy saving and maximize economic benefits; figure 1 As shown, in the proposed model, we consider a two-layer NOMA network architecture in the terahertz frequency band, which includes 1 macro base station MBS and K small base stations SBSs. There are M macrocell users MUEs randomly distributed around the MBS, and each SBS can cover one femtocell user FUEs. For convenience of discussion, this embodiment assumes that all base stations BSs and user UEs are equipped with only one...

Abstract

The invention discloses a network resource scheduling method and device, and the method and device are used for a double-layer NOMA network scene in a terahertz frequency band, and the method comprises the steps: carrying out the modeling of a terahertz indoor propagation environment, and obtaining a channel model suitable for the scene; decoupling the joint resource scheduling problem into two sub-problems of sub-channel allocation and power allocation; based on a whale optimization algorithm, solving the channel model to obtain an optimal solution of sub-channel allocation and power allocation so as to realize network resource scheduling according to the obtained optimal solution of sub-channel allocation and power allocation. According to the method, better network resource scheduling can be realized, green and energy-saving effects are ensured, the method is applied to a terahertz-band NOMA multi-user system network scene, and the network energy effectiveness and economic benefitscan be improved to the maximum extent.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a network resource scheduling method and device. Background technique [0002] In the coming 6G era, the number of mobile devices continues to increase, and the demand for data rates is exploding. How to improve the rate of wireless networks has become an urgent problem in the field of wireless communications. [0003] In fact, the existing needs of users can only be met by increasing the carrier frequency to obtain more spectrum resources. Under such circumstances, terahertz waves have received extensive attention from industry and academia due to their huge bandwidth and great potential in future wireless communications. [0004] In the electromagnetic spectrum, the frequency of terahertz waves is between 0.1THz and 10THz, and the wavelength is between 0.3mm and 3mm. Therefore, terahertz waves have the advantages of both microwaves and light waves, can pr...
