Joint Channel Allocation and Power Control for Uplink NOMA-Assisted Multi-UAV Networks

Algorithm 1

Channel allocation algorithm.

1://initialization: each UAV sends a request packet (coordination, speed, channel state, etc.) to GB, =;

2: Get the nonascending order of channel gains, ;

3: Mark the UAV with channel gain as ;

4: Obtain the sets {,,, };

5: for each subset , do

6: for =; ; do

7: if the set is not empty, then

8: Add the th component in set to subset ;

9: Judge whether the components in subset meet constraint (8);

10: If not, adjust the power level of corresponding component in ;

11: end if

12: end for

13: =-1;

14: end for

15: If all UAVs are assigned to the special channels, the algorithm is terminated;

16: return .
