Senior Engineer (Wireless communication PHY layer).

Patent №:  12261802 – Method for transmitting/receiving PDSCH in wireless communication system, and device therefor. A terminal receives configuration info for semi-persistent downlink transmission and CORESETs, then receives DCI via the configured CORESETs. Based on the DCI, it activates and receives the corresponding semi-persistent PDSCH.

Patent №: 12261664 – Method and apparatus for transmitting and receiving channel state information in wireless communication system. A method and apparatus for transmitting and receiving channel state information (CSI) in a wireless system are disclosed. The method includes receiving CSI configuration from a base station, receiving reference signal (RS) resources via different downlink spatial filters, and sending CSI—such as layer 1 SINR—back to the base station based on the RS resources.

Principal Engineer at Samsung Electronics.

Patent №: 12262361 – Method and apparatus for transmitting and receiving physical-layer channel in consideration of priority in wireless communication system. The disclosure relates to a communication method and system combining 5G and IoT technologies to support advanced services like smart homes, cities, cars, healthcare, and more. It describes a method and apparatus for transmitting and receiving a physical-layer channel in a wireless system, taking priority into account.

Patent №:  12261785 – Apparatus and method for multiplexing switching of integrated access and backhaul node in wireless communication system. The disclosure relates to 5G/6G systems enabling high data rates. A method by an IAB node includes receiving multiplexing configuration info (SDM, FDM, TDM) from an upper IAB node, performing a fallback from SDM or FDM to TDM, and using the configuration to handle DU data transmission and reception accordingly.

Patent №:  12238017 – Method and apparatus for transmission and reception in wireless communication system supporting scalable frame structure. Example embodiments describe a data transmission system where both devices share a master key. The transmitter uses it to create a diversified key, encrypt data, and secure a counter value. The receiver derives the same key to decrypt the data and validate the counter.

Jeffrey Rule

Product Director, Machine Learning.

Patent №:  12261960 – Systems and methods for cryptographic authentication of contactless cards. Example embodiments describe a data transmission system where both transmitting and receiving devices share a master key. The transmitting device generates a diversified key, encrypts data, and protects a counter value before sending. The receiving device uses the master key to derive the same diversified key, decrypt the data, and verify the counter value.

Patent №:  12261832 – Message authenticated communication sessions. Aspects described enable generating a message to the recipient before a communication session begins. The system monitors apps and devices to detect session initiation, then uses data and a machine learning model to create a draft message for the initiating user. These messages can help authenticate the user with the recipient.

Patent №:  12261655 – Dynamic power levels in NFC card communications. Various embodiments dynamically adjust NFC reader power in a computing device based on feedback from a contactless card. The card sends a message with a checksum, which the device verifies. If the checksums don’t match, indicating an error, the device temporarily increases NFC power to improve communication.

Patent №:  12260393 – Devices and methods for selective contactless communication. A card includes an antenna, processor(s), and memory with two applications. It detects input and identifies the request type. If the request follows the EMV standard, it activates the first app for contactless payments via NFC. If the request follows the NDEF standard, it activates the second app for identification or verification, also via NFC.
