Latest Patents
Hugh Wang's latest patents include a method for time synchronization of a satellite positioning system enabled mobile receiver and base station. This innovation focuses on synchronizing mobile receivers and cellular communication network base stations with satellite positioning system clocks. The method involves determining a variable propagation delay for the transmission of assistance messages from the base station to the mobile receiver, which helps in correcting the handset clock. Additionally, local clock drift of mobile receivers and base stations is addressed by calculating a ratio of local and satellite time differences based on sequential time snapshots.
Another significant patent is a transmission power control method that subdivides transmission power steps into multiple sub-steps. In this method, a base station instructs a mobile station to use a defined power step, allowing the mobile station to initially select a maximum power sub-step during the initial transmission. Throughout the call, the mobile station dynamically adjusts the power sub-step based on measured signal reception quality and channel conditions, resulting in improved call completion rates with minimal impact on battery life.
