Demo: Non-classic Interference Alignment for Downlink Cellular Networks
Our demo aims at proving the concept of a recent proposed interference management scheme that reduces the inter-cell interference in downlink without complex coordination, known as non -classic interference alignment (IA) scheme. We assume a case where one main Base Station (BS) needs to serve three users equipments (UE) while another BS is causing interference. The primary goal is to construct...
متن کاملRelay-Aided MIMO Cellular Networks Using Opposite Directional Interference Alignment
In this paper, we propose an interference alignment (IA) scheme for the multiple-input multipleoutput (MIMO) uplink cellular network with the help of a relay which operates in half-duplex mode. The proposed scheme only requires global channel state information (CSI) knowledge at the relay, with no transmitter beamforming and time extension at the user equipment (UE), which differs from conventi...
متن کاملUplink-Downlink Duality of Interference Alignment in Cellular Relay Networks
This paper focuses on signal space interference alignment for the uplink and downlink transmissions in a cellular relay network with multiple cells where a single base station serves multiple mobile stations in each cell and several amplifyand-forward relays are deployed. We show that the interference alignment problems in the uplink and downlink transmissions are a pair of formally dual proble...
متن کاملInterference Cancellation trough Interference Alignment for Downlink of Cognitive Cellular Networks
In this letter, we propose the interference cancellation through interference alignment at the downlink of cognitive cellular networks. Interference alignment helps the spatial resources to be shared among primary and secondary cells and thus, it can provide higher degrees of freedom through interference cancellation. We derive and depict the achievable degrees of freedom. We also analyse and c...
متن کاملElements of Cellular Blind Interference Alignment - Aligned Frequency Reuse, Wireless Index Coding and Interference Diversity
We explore degrees of freedom (DoF) characterizations of partially connected wireless networks, especially cellular networks, with no channel state information at the transmitters. Specifically, we introduce three fundamental elements — aligned frequency reuse, wireless index coding and interference diversity — through a series of examples, focusing first on infinite regular arrays, then on fin...
