Latest Patents

Lee is named on 1 patent: “Device and Method for Identifying Polarization for Uplink Transmission in Wireless Communication System.” The invention describes an electronic device that receives downlink control information from a base station and selects a polarization for an uplink signal using a preconfigured table. The selection can depend on variables such as the antenna module, operating band, or channel, particularly when the control information does not specify a transmitted precoding matrix indicator. The approach supports polarization selection for wireless systems designed to provide higher data rates than 4G LTE.

Career Highlights

Lee’s listed patent reflects work on wireless communication technology at Samsung Electronics Ltd. It focuses on how an electronic device can determine the polarization used to transmit an uplink signal.

Collaborations

The patent lists Jaegon Ghim and Heeyoon Kwak among Lee’s coworkers. Their inclusion indicates a collaborative context for the invention, though the provided information does not specify their individual contributions.

Conclusion

Yunbum Lee’s patent concerns a practical method for selecting uplink polarization in wireless communication systems, contributing to the development of higher-rate 5G and pre-5G technologies.
