Abstract
In this paper, we study the feasibility of interference neutralization (IN) in partially connected relay-aided multi-input-multi-output (MIMO) interference broadcast channel (IBC), where each relay only communicates with users in the same cell. Due to partial connectivity, there is no need to exchange channel information among the relays in different cells. We first present the necessary and sufficient condition for IN feasibility using linear transceiver. We then provide the minimum relay configuration required to support the maximal number of data streams without interference. Finally, the achievable degrees-of-freedomregion is obtained.
