    Abstract: Provided is an operating method of a first apparatus communicating with a second apparatus in a wireless local area network (WLAN) system including the first apparatus and the second apparatus. The operating method of the first apparatus includes obtaining channel characteristic data with the second apparatus based on a null data packet (NDP) frame received from the second apparatus; generating beamforming feedback information and a feedback frame based on a class of a channel determined by applying a machine learning algorithm to the channel characteristic data; and transmitting the feedback frame to the second apparatus.

    Abstract: A method includes generating a first aggregated physical layer protocol data unit (PPDU) including a first null data packet (NDP) based on an extremely high throughput (EHT) protocol standard and a second NDP based on an EHT+ protocol standard, which is a next generation of the EHT protocol standard, and transmitting the first aggregated PPDU to a second apparatus in a wireless local area network (WLAN) system. Each of the first NDP and the second NDP has a same duration, and the first NDP is transmitted in a first band and the second NDP is transmitted in a second band that is different from the first band.

    Abstract: A beamformee device includes a channel estimator, first and second beamforming matrix providers and a dimension reduction unit. The channel estimator receives a NDP through a channel, and obtains channel information of the channel based on the NDP. The first beamforming matrix provider provides wideband beamforming matrices based on the channel information. The dimension reduction unit generates equivalent channel information based on the wideband beamforming matrices. The second beamforming matrix provider provides beamforming matrices based on the equivalent channel information. The wideband beamforming matrices and the subcarrier beamforming matrices are fed back to the beamformer device. Any one or any combination of the plurality of wideband beamforming matrices and the plurality of subcarrier beamforming matrices are selected from codebooks.
