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 present application provides a method for determining a CP. A STA performs channel estimation, determines a CP value according to the result of channel estimation, and sends indication information to an AP, wherein the indication information is used for indicating the CP value, so that the AP may choose a suitable CP according to the indication information. Therefore, overhead may be reduced and system throughput may be optimized.

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: The present disclosure relates to Hybrid Automatic Repeat Request (HARQ) in wireless communication technologies, particularly HARQ for IEEE 802.11, i.e. HARQ for Wi-Fi. One example transmitting device is configured to encapsulate a data unit in a container unit, and encode the container unit into a codeword set of one or more codewords. One example receiving device is configured to receive, from a transmitting device, at least one codeword set of one or more codewords, decode the codewords of the codeword set to obtain a container unit, and decapsulate the container unit to obtain a data unit. A bit-size of the container unit is equal to a bit-size of the codeword set in the transmitting device and the receiving device.
