Traffic Load-Based Spectrum Trading between Two Mobile Network Operators in HetNets Using Interference Management Technique

Algorithm 1

Conventional RB Allocation.

(1)	and set of macro and small cell users
(2)	User Association is performed for all and based on SINR using (3)
(3)	Required number of RBs are calculated using (8) and (9) for each macro and small cell user, respectively
(4)	Allocate required number of RBs to each user and based on best SINR calculated in Step 2
(5)	Initialize set of users whose data rate is below the threshold
(6)	Calculate for each small cell user with selected SBS using (4)
(7)
(8)	or store that each user in
(9)	end
(10)	end
(11)	Repeat Step 7 for all small cells
