Non-Orthogonal Multiple Access Enabled Mobile Edge Computing in 6G Communications: A Systematic Literature Review

Round 1

Reviewer 1 Report

Please find my comments below:

 

As a survey, the first and second paragraphs have not impressed me. The background for the NOMA-enabled MEC should be more detailed and convincing. Some standards, policies, and implements should be discussed. 

 

It is some strang for me that after going through this paper, this paper indeed is not a survey paper. The main contribution is introducing SLR into NOMA-MEC networks. But the main motivation is not highlighed well. Also the technicality is not well introduced

Reviewer 2 Report

The paper is well presented and well collect a considerable amount of literature works, however, a revision is required, especially in terms of grammar and technical aspects. In addition, the authors are recommended to provide more technical illustrations, and it would be better if they chose performance metrics to compare among the NOMA and MEC techniques they mentioned from the literature review. For example, in the table within this manuscript, include figures depicting complexity comparisons among the proposed techniques. This would give the paper a more technical look and presentation.

Reviewer 3 Report

The authors of the paper "Non-Orthogonal Multiple Access Enabled Mobile Edge Computing in 6G Communications: A Systematic Literature Review" made a systematic literature review by using the PRISMA statement.

The paper is interesting however it has a lot of issues and inaccuracies:

-fig 2 does not provide any contribution, moreover, the continuous line instead of a bar chart has no sense.

- fig 3 should be described more in detail

- in Section 4 rows 287-292 the authors wrote that IEEE has the greater number of articles published, however from table 3 is it possible to observe that ieee as around 970 papers but in WOS more than 7000 papers have been published.

-a taxonomy is missing

Reviewer 4 Report

This paper focuses on two concepts related to NOMA and MEC structure, and deeply considers NOMA's requirements for MEC, resource and performance allocation, as well as its application in 6G network.

Problems in this paper:

1) The resource and performance analysis of NOMA's MEC system in this paper is deficient and needs to be further strengthened.

2) The analysis of relevant documents is not complete.

It is suggested to change to other journals.

Reviewer 4 Report

Non-orthogonal multiple access (NOMA) has been proposed as an alternative to classical orthogonal multiple access (OMA) because it can increase the number of users supported, improve spectral efficiency, and reduce latency.

In this study, the author considered the interoperability between NOMA and MEC, and provided important research content and techniques. In addition, the author also pointed out important unresolved issues and related further research directions and solutions.
