    Abstract: A radio frequency (RF) front end for wireless communications, in particular for use in a half duplex (HD) and/or full duplex (FD) transceiver. The RF front end is based on a quadrature balanced power amplifier (QBPA). The RF front end includes an antenna port for outputting a transmit signal to and receiving a receive signal from an antenna, and a receive port for outputting the receive signal to a signal processing section. Further, the QBPA is configured to receive a transmit input signal at a first port, receive a cancellation input signal at a fourth port, and receive the receive signal at a second port coupled to the antenna port.

    Abstract: A device for determining a received signal as minimum values of a set of values, the device comprising a processor configured to: load a first set of values in a register; identify a maximum value of the first set of values and a minimum value of the first set of values; in the register, replace the maximum value by a value of a second set of values and simultaneously replace the minimum value by a new value, calculated based on the minimum value, to receive an updated first set of values; and repeat previous steps until all values of the updated first set of values are replaced by values of the second set of values.

    Abstract: Disclosed are a physical layer (PHY) protocol data unit (PPDU) transmission method and a related apparatus. The method includes: generating a PPDU, where the PPDU includes a universal signal field (U-SIG), and the U-SIG includes a subfield indicating that the PPDU is a null data packet (NDP); and sending the PPDU. In this way, a beamformee (Bfee) that receives the NDP can identify the NDP earlier. This helps improve efficiency of reading the NDP by the Bfee. The PPDU is an NDP used for a standard after 802.11ax. In a scenario in which wireless communication is performed by using the standard (for example, 802.11be) after 802.11ax, the Bfee can perform channel estimation based on the NDP.

    Abstract: The present disclosure suggests to expand and improve the method of utilizing channel resources in the 802.11be standard by allowing the use of multiple and non-contiguous portions of a channel. Supporting multiple resource units (MRUs) and non-contiguous resource units (RUs) improves the channel utilization by making it more efficient due to enhancing the capability of leveraging the channel selectivity. To this end, a wireless network device for resource allocation is provided and configured to define a non-contiguous MRU in the bandwidth of the channel. The channel comprises a plurality of RUs, and the MRU is defined based on non-punctured RUs after puncturing one or more of the RUs of the channel, and/or is defined by aggregating two or more non-adjacent RUs of the channel.

    Abstract: An access point, AP (110), configured to perform a sounding procedure with one or more associated non-AP stations (120) in a wireless local area network (100) is provided. The AP (110) comprises a processing circuitry (111) configured to generate a null data PPDU announcement, NDPA, frame, wherein the NDPA frame comprises for each of the one or more associated non-AP stations (120) a station info field. The station info field comprises a partial BW info subfield, including a feedback bitmap and an indication of a resolution and/or a range of the feedback bitmap with a 20 MHz or 40 MHz subchannel resolution for a Sounding NDP with a bandwidth of up to 320 MHz. The AP (110) further comprises a communication interface (113) configured to transmit the NDPA frame to the one or more associated non-AP stations (120). Moreover, a corresponding non-AP station (120) is disclosed.
