Embodiment Construction

[0041] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0042]The embodiment of the present invention discloses a two-stage mobile edge computing communication method based on NOMA and UAV assistance, which is applied to a communication system. The communication system includes a user group, a relay UAV group, and a ground base station. The user group passes The relay drone group communicates with the base station on the ground. Such as figure 1 As shown, it specifically includes the following steps:

[0043] S10, each user in the user group executes: obtain the task amount of each user in the user group, and calculate the average task amount of the users in the user group, when the user's task amount is greater than or equal to the average task amount, The user is determined as a fully unloaded user, and the fully unloaded user completely offloads its task load to the relay drone determined in ...

Abstract

The invention discloses a two-stage mobile edge computing communication method based on NOMA and unmanned aerial vehicle assistance, which is applied to a communication system, the communication system comprises a user group, a relay unmanned aerial vehicle group and a ground base station, and the user group communicates with the ground base station through the relay unmanned aerial vehicle group. Each user in the user group executes the following steps that: the task load of each user in the user group is acquired, the average task load of the users in the user group is calculated, and when the task load of the user is greater than or equal to the average task load, the user is determined as a completely unloaded user; the complete unloading user completely unloads the task load to the relay unmanned aerial vehicle determined in the relay unmanned aerial vehicle group; the relay unmanned aerial vehicle receives the task amount sent by the complete unloading user and unloads a part of the received task amount to the ground base station according to the calculated task unloading ratio; user task data unloading is reasonably carried out in the communication system, and the performance of the communication system can be improved.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and in particular relates to a two-stage mobile edge computing communication method based on NOMA and UAV assistance. Background technique [0002] With the development of mobile wireless communication technology and the increase in the number of mobile wireless communication users, the data traffic has shown explosive growth. Unmanned aerial vehicle (UAV), as an emerging mobile device, has become an important part of the fifth generation mobile communication technology (5G) and future mobile wireless communication network due to its high degree of freedom and operability. . UAV-assisted mobile wireless communication can provide users with high-quality and various types of communication services due to its Line of Sight (LOS)-dominated channel environment and high flexibility. [0003] However, also due to the channel environment dominated by UAV line-of-sight links, UAV-assisted m...
