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.

Abstract: The subject specification comprises a cognitive relay communications management (CRCM) component associated with a primary communication system, wherein the CRCM component controls relaying at least a portion of transmitted communications from a secondary source device (SSD) transmitting data to a secondary destination device (SDD) associated with a secondary communication system, in accordance with a specified relay protocol, such as a buffered decode-and-forward protocol. The CRCM component identifies when the secondary relay station (SRS) is not transmitting on the relay-destination (R-D) link and the source-relay link is not blocked, and, in such instance, allows transmission of a packet from the SSD to the SRS. The SRS forwards the packet to the SDD when the CRCM component identifies when the R-D link is not blocked. The SRS and/or SSD remove the packet from their respective queues when an acknowledgement message(s) is received from the SDD and/or SRS, respectively.
