Resource Allocation Combining Heuristic Matching and Particle Swarm Optimization Approaches: The Case of Downlink Non-Orthogonal Multiple Access
Round 1
Reviewer 1 Report
Some suggestions to improve the paper:
-A better title for subsection 1.3 can be 'Novelty of this work and structure of the paper'
-Line 106-110, the numbering of the sections are not consistent with rest of the paper. should be secion2, section 3 etc.
-Please consider re-writing line 202-204, since it contains grammatical error.
-From the power budget of 46 dBm it looks like you are considering a macro BS. What is the justification of using 500m of cell?
-I can see that you have mentioned that users are deployed randomly. but how are you modeling the user arrival and death rate?

Reviewer 2 Report
This paper investigates the case of downlink Non-Orthogonal Multiple Access in resource allocation combining heuristic matching and particle swarm optimization approaches. Even though this topic is interesting and timely, I have the following minor concerns.
There are three drawbacks for the paper:
In the system description and problem formulation of section 2, NOMA scheme described by SIC is not detailed enough, the authors are suggested to have a more detailed derivation process. In the part of simulation results of the paper, the authors can try to do more comparison, and the performance parameters should be clear. In the channel matching and power allocation scheme in section 3, it is very important that the authors should clearly indicate the initial requirements when discussing the algorithm. Before giving the simulation, it’s better to make a simple introduction to the system scene.Author Response
