Interference Mitigation through Successive Cancellation in Heterogeneous Networks

Algorithm 2

High Level MS-OIC scheme taking one MeNB and its co-located FeNBs as an example.

Outer loop: Search MUE_𝑗 for MeNB_𝑖, 𝑖∈𝑆, to maximize the CoMP set wide weighted sum

throughput. For each MUE_𝑗 for MeNB_𝑖, 𝑖∈𝑆, go to the following steps.

 Step  1: Pair (MeNB_𝑖, MUE_𝑗, FeNB_𝑘, FUE_𝑘) to perform MS design (by Algorithm 4) to

 obtain the precoders for these two eNBs.

 Step  2: For each of the other femtocells located in the macrocell of MeNB_𝑖, perform

 OIC design assuming MeNB_𝑖, 𝑖∈𝑆, use the precoders designed in Step  1.

 End of Steps
