Latest Patents

One of his latest patents is titled "Method and apparatus for aligning interference using a feed forward index in a hierarchical cell communication system." This invention provides an innovative approach to interference alignment without the need for full feed-forwarding. It allows a macro base station to generate transmission beamforming vectors that nullify interference channels to pico terminals while also managing interference among macro terminals. The effective interference channels are determined based on the reception beamforming vectors of the pico terminals. The macro base station transmits a feed-forward indicator (FFI) to the macro terminal, which helps in obtaining information related to the reception beamforming vector.

Another notable patent is "Communication apparatus and precoding method based on multiple cells and multiple users." This invention describes a communication apparatus capable of generating a precoding matrix that includes precoding vectors designed to cancel or align interference among multiple terminal devices. The terminal device estimates the channel formed with the communication apparatus to effectively manage interference signals.
