Abstract: Briefly, in accordance with one or more embodiments, an apparatus of a user equipment (UE) comprises one or more baseband processors to generate a first set of one or more radio resource control (RRC) messages to create a packet data convergence protocol (PDCP) and RRC entity at a donor Fifth Generation evolved NodeB (DgNB), and to generate a second set of one or more RRC messages to create a radio link control (RLC) entity at a serving relay node (RN) to couple with the DgNB in a multi-hop relay network, and a memory to store the first set of one or more RRC messages or the second set of one or more RRC messages.

Abstract: An electronic device may be provided with control signal generation circuitry that generates a differential pair of control signals, power supply circuitry that generates a bias voltage, and an antenna having a tuning circuit. First switching circuitry may be coupled to the power supply circuitry and the control signal generation circuitry. Second switching circuitry may be coupled to the tuning circuit. A pair of control lines may be coupled between the first and second switching circuitry. In a first switching mode, the power supply circuitry may transmit the bias voltage to the tuning circuit over one of the control lines. The bias voltage may charge storage circuitry coupled to the tuning circuit. In a second switching mode, the control signal generation circuitry may transmit the differential pair of control signals to the tuning circuit. The tuning circuit may be powered by the storage circuitry in the second switching mode.
