Dynamic Fractional Frequency Reuse Diversity Design for Intercell Interference Mitigation in Nonorthogonal Multiple Access Multicellular Networks

Algorithm 1

Fair resource allocation for edge and center users.

(1) Divide total bandwidth B into   &    with a

(2) total of L channels.

(3) for each u_b in U_b

(4) if do

(5) Assign a single channel.

(6)

(7)if   do

(8)if do

(9)Assign another channel to reduce

(10) required power & meet .

(11)

(12) else do

(13) Set total assigned power of CE user

(14) group to .

(15) end

(16) end

(17)

(18) else if do

(19) for channels in

(20) Map a center user on the same channel as

(21) an edge user.

(22) Allocate power as per and considering

(23) power allocation of edge user as well on

(24) the same channel using (10).

(25) ;

(26)

(27) end

(28) for channels in

(29) Assign channel and power to remaining

(30) users from as per rate requirement .
