Latest Patents
Liu's latest patents include innovative designs for scrambling sequences aimed at enhancing multi-mode block discrimination on downlink control information (DCI) blind detection. One of his notable inventions focuses on methods and devices for polar encoding and decoding control information that is modulated based on identifiers of the transmitter and/or receiver. This invention describes the application of separate scrambling masks to different bit fields within a coded DCI message, derived from user equipment (UE)-specific identifiers, UE group identifiers, or base station identifiers. Additionally, Liu has developed techniques for using frozen bits of the polar code to encode and transmit hybrid automatic repeat request (HARQ) acknowledgment messaging, facilitating early retransmission of unsuccessful downlink messages. Another patent emphasizes scrambling sequence design for embedding receiver IDs into frozen bits for blind detection, which helps mitigate intercell interference and ensures that the receiver is the intended recipient.
