    Abstract: A device resolves a collision between its transmission and a simultaneous transmission of another device. The device is configured to interrupt its transmission, determine a negotiation signal, and determine at least one available resource to occupy with the negotiation signal during a negotiation period. Further, the device is configured to transmit the negotiation signal on the at least one available resource and simultaneously receive a negotiation signal on another resource from at least one other device during the negotiation period. Then, the device is configured to decide, based on all negotiation signals, whether to retransmit the interrupted transmission after the negotiation period.

    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.
