Abstract: Various aspects provide a radiohead circuit and a communication device including the radiohead circuit. In an example, the radiohead circuit includes an antenna interface, a radio frequency front end configured to receive a wireless communication signal via the antenna interface, and a processor configured to perform an initial signal detection to detect if a wireless communication signal has been received based on whether a signal the processor received from the radio frequency front end fulfill a predefined radiohead circuit detection criterion, generate an initial signal detection information comprising an information as to whether the wireless communication signal has been received based on the initial signal detection; and provide the initial signal detection information to a communication interface for a final signal detection; the communication interface configured to couple the processor to a radiohead circuit-external processor external to the radiohead circuit.

Abstract: Devices, methods, and media described herein can employ the central 26-tone allocation of 802.11ax for transmission of NB beacons and wake-up packets. Having a dedicated narrowband channel for transmission of NB beacons and/or wake-up packets improves the overall spectrum efficiency. Further, the embodiments may use the central 26-tone subchannel for LP-WUR and legacy IEEE 802.11ax OFDMA transmission, but not for the LP-NB IoT devices that have a OFDM waveform. This configuration reduces the implementation cost and test/certification time & cost of IoT devices.

Abstract: A wireless device includes a controller configured to identify a scheduled transmission including a first section having a first bandwidth and a second section having a second bandwidth, select a transmit power limit for the scheduled transmission based on a relative duration of the first section compared to the second section, and select a transmit power value based on the transmit power limit, and a transmitter configured to perform the scheduled transmission with a transmit power indicated by the transmit power value.

Abstract: Today's IEEE 802.11 devices operating in the 2.4/5 GHz bands use a 20 MHz channel as a basic operation unit to maintain coexistence with other 802.11 devices. One exemplary aspect is directed toward using a narrower signal bandwidth (e.g. 2 MHz) in the 2.4/5 GHz bands to reduce transmit/receive power consumption or increase transmission range. However, one problem with introducing a narrow bandwidth signal is how to maintain the coexistence between a legacy IEEE 802.11 device that uses a 20 MHz signal bandwidth and a new IEEE 802.11 device that uses a narrower signal bandwidth.
