In some embodiments, a front-end architecture includes a switching assembly configured to provide switching for two or more frequency bands. In some embodiments, the switching assembly includes at least one coupler configured to couple a signal associated with the switching assembly. The front-end architecture can also include a diplexer circuit including a first filter configured to pass a first frequency band, a second filter configured to pass a second frequency band, and a first electrostatic discharge network configured to dissipate electrostatic energy associated with the first and second frequency bands from the front-end architecture.

Provided is an electronic device that includes a communication processor; a transceiver electrically connected to the communication processor; a first power amplifier electrically connected to the transceiver; a first antenna electrically connected to the first power amplifier; and a first supply adjustor electrically connected to the communication processor and the first power amplifier. The communication processor can be set to perform a first determination about whether a carrier bandwidth part of a first signal transmitted through the first antenna exceeds a first threshold value, perform a second determination about whether the power of the first signal exceeds a second threshold value, select a first tracking mode as an envelope tracking mode or an average power tracking mode on the basis of at least a portion of the first determination and the second determination, and control the first supply adjustor using the selected first tracking mode.

Systems and methods described herein are provided for beamforming and uplink control and data transmission techniques. Such techniques enable a UE to maintain at least one beam process for operation with multiple beams and/or points. A beam process may be indicated for transmission or reception over a downlink or uplink physical channel. Power, timing, and channel state information may be specific to a beam process. A beam process may be established as part of a random access procedure in which resources may be provisioned in random access response messages. Techniques are provided to handle beam process failures, to use beam processes for mobility, and to select beams using open-loop and closed-loop selection procedures.
