Latest Patents

Lee’s listed patent is “Device and Method for Multi-Subscriber Identity Module Wireless Communication.” It describes an operating method for user equipment that supports dual-SIM dual-active (DSDA) communication.

The method enables a device to communicate with a first base station through a first SIM while responding to a request from a second SIM to communicate with another base station. If the device does not have additional radio-frequency transmission paths available, it allocates at least one path to each SIM using time-division multiplexing (TDM). This approach supports communication across two networks while managing the device’s available radio resources.
