Abstract: A resonant converter has a primary resonant tank circuit and a secondary resonant tank circuit. An inverter circuit converts an input DC voltage received by the resonant converter at an input voltage node to a pulsating signal that is fed to the primary resonant tank circuit to generate a resonant tank current that flows through a primary winding of a transformer. The resonant tank current induces current in a secondary winding of the transformer. The induced current is rectified by a rectifier and the rectified signal is filtered to generate an output DC voltage at an output voltage node. The secondary resonant tank circuit is disposed between the secondary winding of the transformer and the output voltage node, and a tank node of the secondary resonant tank is connected to the primary resonant tank circuit through the inverter circuit.

Abstract: Apparatus and methods are provided for GNSS position fix in connected state. In one novel aspect, the UE reports GNSS assistance information to the network entity in the NTN system, wherein the GNSS assistance information includes a GNSS position fix time duration for measurement. When the UE detects the GNSS position out-of-date condition in the RRC_CONNECTED stated, the UE determines whether the GNSS position fix time duration for measurement is smaller than the network scheduled duration for GNSS measurement and performs the GNSS position acquisition procedure in the RRC_CONNECTED state if determined yes. In another embodiment, the network scheduled duration for GNSS measurement is configured for the UE to re-acquire GNSS position fix in the RRC_CONNECTED state and may further include duration to re-acquire downlink (DL) synchronization with or without NTN system information block (SIB). In one embodiment, the network scheduled duration for GNSS measurement is a new scheduling gap or a GNSS timer.
