Abstract: Systems, methods, and apparatus are described that employ a partial interference alignment scheme in conjunction with an interference detection scheme to mitigate interference in quasi-static multiple input multiple output (MIMO) channels. In an aspect, sets of transmitter and receiver pairs are determined based on feasibility of alignment of the transmitters at the receivers of the sets in accordance with an interference alignment scheme and path loss associated with signal transmissions between the transmitter and receiver pairs, wherein the sets include different alignment assignments of the respective transmitters at the respective receivers of the sets. The alignment assignments can include different numbers of the transmitters aligned at the receivers of the sets. A set is then selected from the sets that contributes to an interference profile at the receivers that facilitates interference detection at the receivers.

Abstract: Systems, methods, and apparatus are described that employ specially designed interference patterns to build an in-band side channel without degrading the effective throughput of the main channel. Transmitter and receiver pairs implement a two-stage dynamic interference mitigation scheme based on the partial connections in limited dimension MIMO interference channels. The first stage determines the stream assignments and the subspace constraints for beamforming vectors and zero-forcing vectors based on the partially connected topology such as the path loss, shadowing and spatial correlation. The second stage determines the beamforming vectors and the zero-forcing vectors based on the instantaneous channel state information over the subspaces obtained from the first stage. In an aspect, a controller device implements the first and second stage and assigns the transmitter and receiver pairs to perform interference alignment using the stream assignments and beamforming and zero-forcing vectors respectively.
