Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0029] At present, the communication requirements of the fifth-generation mobile communication technology mainly focus on the following two aspects:

[0030] 1. Enhanced Mobile Broadband (eMBB, Enhanced Mobile BroadBand) scenarios requiring high transmission rates. This scenario means that in the mobile communication environment, users actively seek higher communication quality and more extreme communication experience. For example, some virtual reality (VR, Virtual Reality) games, important calls, etc.

[0031] 2. Massive machine type communication (mMTC, massive Machine Type of Communication) that requires high access, that is, large-scale IoT scenarios. This scenario refers to trying to ensure that more users can access the network in an application environment with high ...

Abstract

The embodiment of the invention discloses a service-oriented spectrum slicing method and device and a computer storage medium. The method can comprise the following steps: randomly allocating subcarriers to each user equipment based on a subcarrier number upper limit corresponding to a set communication demand scene and a communication demand scene where each user equipment is located; wherein thecommunication demand scene comprises a first communication demand scene and a second communication demand scene; obtaining residual bandwidth according to the total bandwidth of the system and subcarriers randomly distributed to all user equipment; determining candidate user equipment from the user equipment in the first communication demand scene according to a set selection strategy; quantitatively allocating subcarriers to at least one candidate user equipment based on the residual bandwidth, and obtaining the updated residual bandwidth; and allocating subcarriers to the user equipment inthe second communication demand scene according to the updated residual bandwidth.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a service-oriented spectrum slicing method, device, and computer storage medium. Background technique [0002] With the maturity of the fifth generation mobile communication technology (5G, 5th Generation), more and more users access cognitive radio networks. Scarce spectrum resources have gradually become one of the most important factors affecting user communication quality. It can be seen from the frequency allocation diagrams of various countries in the world that spectrum resources from 3KHz to 300GHz are authorized to different radio services, and spectrum resources in some frequency bands (such as 1164MHz to 3000MHz) have a high utilization rate and are even very crowded. At present, there are also schemes that use relatively high-frequency idle spectrum resources for communication. However, as the frequency increases, the transmission ...
