Latest Patents

One of Heun-Chul Lee's latest patents is a scheme for transmitting reference signals in wireless communication systems. This patent describes methods, systems, and apparatuses for evolved NodeB (eNB), User Equipment (UE), and chipsets in cellular communication systems. The method for a UE includes receiving a Channel State Information Reference Signal (CSI-RS) transmitted by an eNB according to a specific pattern in a time-frequency resource grid. The UE measures the state of the transmission channel using the CSI-RS, generates channel state information based on the measurement, and transmits this information as feedback. Additionally, the UE receives a downlink signal that includes data and a Cell-specific Reference Signal (CRS) from the eNB, estimating the transmission channel using the CRS to acquire the data.

Another notable patent involves a method and apparatus for blind detecting a transmission mode for interference cancellation. This invention provides methods and apparatuses for determining an interference transmission mode (TM) at a communication device in a cellular communication system. The process includes receiving a first signal that comprises both a serving signal and an interference signal, and projecting the received signal onto multiple projection vectors to determine a traffic-to-pilot ratio (TPR) decision metric for the interference signal.
