Abstract: A transistor assembly with gate current shunting capability includes a first N-channel field effect transistor (FET) having a first gate, a first drain electrically coupled to a first power supply, and a first source. A first pull-down circuit element is electrically coupled to the first gate. A first switching device is electrically coupled in series with the first pull-down circuit element. A control circuit, at least partially powered by a second power supply, generates a first control signal to control the first switching device and thereby control an operating state of the first FET. A capacitor and a second FET are collectively configured to shunt current away from the first gate during a pre-power operating state in which the first power supply is active and the second power supply is inactive. A second switching device discharges a gate-to-source capacitance of the second FET when the second power supply becomes active.

Abstract: The present disclosure is related to the field of telecommunication, and in particular, to enhancement for uplink data transmission.

Abstract: Systems and method provide for uplink carrier aggregation (UL CA) that is configured for a User Equipment (UE), and transmissions on multiple UL carriers by one power amplifier (PA). When a base station (e.g., a gNB) indicates the UE should switch its UL waveform from Cyclic-Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM) to Discrete Fourier Transform Spread OFDM (DFT-S-OFDM) for Physical Uplink Shared Channel (PUSCH) transmission in one or more UL carriers, the base station expects that the UE transmit power on a particular carrier can be increased, the carrier for which a UL coverage issue (e.g., low signal strength, signal to noise ratio, interference, etc.) is found. UL waveform switching from CP-OFDM to DFT-S-OFDM can improve the lower bound of PCMAX, namely the total UE transmit power on UL carriers of intra-band CA.
