The disclosure is generally directed to systems and methods for controlling electrical power outlets in a vehicle. An example method executed by a processor of an electrical power outlet controller includes detecting a transitioning of a vehicle to a drive mode and further includes disconnecting, based on the transitioning, electrical power supplied to a first electrical power outlet in the vehicle. The transitioning of the vehicle to the drive mode may be detected based on a transition of a drive selector of the vehicle from a park position to a drive position. In another example method, the processor, detects the vehicle in motion and disconnects electrical power supplied to a second electrical power outlet in the vehicle. The first electrical power outlet and/or the second electrical power outlet are accessible from outside the vehicle, and may, for example, be located outside a cabin area of the vehicle.

A communication system includes a communication apparatus and a base station. The communication apparatus includes a Discrete Fourier Transform (DFT) transformer which transforms a time-domain signal into a frequency-domain signal with a DFT size that is a product of powers of a plurality of values; a mapper which maps the frequency-domain signal on a plurality of frequency bands, each frequency band being located at a position separate from position(s) of other(s) of the plurality of frequency bands; and a signal generator which generates a single carrier-frequency division multiple access (SC-FDMA) time-domain signal from the mapped signal. The base station includes a receiver which receives the SC-FDMA time-domain signal; a combiner which generates the frequency-domain signal from the SC-FDMA time-domain signal; and a transformer which transforms the frequency-domain signal into the time-domain signal with an inverse Discrete Fourier Transform (IDFT) having the DFT size.

A cellular communication device is configured to use Non-Standalone Architecture (NSA) for communicating with a cellular communication network using 4.sup.th-Generation (4G) Long-Term Evolution (LTE) and 5.sup.th-Generation (5G) New Radio (NR) radio access technologies. In NSA mode, the device may receive separate transmit power control commands for LTE and NR transmissions, respectively. In some situations, the cellular communication device may be commanded to use LTE and NR transmit powers that when combined would exceed regulatory limits or performance limits. In these situations, LTE and NR uplink transmissions are scheduled to implement time-division multiplexing, so that the LTE and NR uplink transmissions occur during different time intervals rather than concurrently.
