    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: The application relates to an access point type communication device (110) configured to allocate a plurality of random access resources to a set of associated client type communication devices (120a-c). The access point type communication device (110) comprises a controller (111) configured to maintain a set of association identifiers, wherein each identifier of the set of association identifiers is configured to identify a respective client type communication device of the set of client type communication devices (120a-c), as well as a set of random access identifiers. In an embodiment, the access point type communication device (110) further comprises an allocator (113) configured to allocate the plurality of random access resources to the set of client type communication devices (120a-c) on the basis of the set of random access identifiers.

    IPC: H04L25/03

    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: 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.

    Abstract: A first access point (AP) in a wireless local area network (WLAN) is configured to communicate with one or more non-AP stations associated with the first AP and at least one second AP. The first AP includes a communication interface configured to receive, from the one or more non-AP stations, a first subset of uplink packets transmitted by the one or more non-AP stations to the first AP and receive, from the at least one second AP, a second subset of the uplink packets transmitted by the one or more non-AP stations to the first AP. Moreover, the first AP comprises a processing circuitry configured to determine the uplink packets based on the first subset and the second subset.
