    Abstract: An operation method of a first device may comprise: receiving, from a second device, first configuration information signaled for CLI-related procedures; receiving, from the second device, second configuration information signaled for operating a multiplexing operation of the first device; in response to recognizing, with respect to a first resource, a collision between first DL-UL configuration information indicated by the first configuration information and second DL-UL configuration information indicated by the second configuration information, comparing priorities of the first DL-UL configuration information and the second DL-UL configuration information; and determining a DL-UL configuration applied to the first resource based on the compared priorities.

    Abstract: Disclosed are a frame transmission method using a selective beamforming and a communication apparatus to perform the frame transmission method. The communication apparatus may determine a beamforming matrix based on classification information in which a plurality of subcarriers used for communication is classified into a plurality of frequency units, may map a long training field (LTF) sequence to the beamforming matrix, and transmit a beamforming training (BF-T) frame including the mapped LTF sequence to a plurality of stations, may receive, from the plurality of stations having receiving the BF-T frame, feedback information generated based on a reception strength of the BF-T frame, and may allocate frequency units to data frames to be transmitted to the plurality of stations based on the feedback information, and transmit the data frames using the allocated frequency units. The reception strength of the BF-T frame may be determined at each station for each frequency unit.
