Title: Shugong Xu: Innovator in Wireless Communications
Introduction
Shugong Xu is a notable inventor based in Vancouver, WA, with an impressive portfolio comprising 30 patents. His work primarily focuses on innovations in wireless communication technologies, particularly in the area of voice over Internet Protocol (VoIP) systems.
Latest Patents
Among his most recent innovations is the patent for a method and system for control of discontinuous reception (DRX) by a mobile device in a wireless communications network. This technology utilizes autonomous DRX control post-initial VoIP traffic setup. When a mobile device sends a negative-acknowledgement signal (NACK), indicating a missed VoIP packet, it autonomously engages a predetermined delay to receive the retransmission. This delay correlates with the time required for the base station to process the NACK and prepare for retransmission. During the transmission or retransmission of VoIP packets, reception is temporarily deactivated, then reactivated after a preset delay to receive either an acknowledgment signal (ACK) or a NACK. Notably, VoIP packets may be sent from the mobile device before those from the base station, optimizing the communication process.
Career Highlights
Shugong Xu has contributed his expertise while working with esteemed organizations such as Sharp Laboratories of America, Inc. and Huawei Technologies Co., Limited.
