Considering the time duplex division (TDD)-based cellular network, this paper investigates the uplink/downlink interference under the framework of centralized-radio access network (C-RAN). According to different uplink/downlink configurations within three neighboring cells, two fundamental cases are discussed, which can be further classified into several scenarios. For the sake of tackling this kind of interference, the interference alignment (IA) transceivers are studied case-by-case… CONTINUE READING
