FIELD: wireless communication.
SUBSTANCE: to achieve the technical result, a data processing system processor generates and transmits a basic service set (BSS) load element, comprising a high-efficiency station (STA) count field, frequency underload field and spatial flow underload field. HE STA count field indicates the total number of HE STAs associated, at a given moment in time, with the BSS, the frequency underutilized field indicates the frequency domain resource underutilization, and the underutilized spatial flow field indicates underutilized spatial domain resource. Frequency underutilization field is calculated based on orthogonal frequency division multiple access (OFDMA) resource unit (RU) size, and the spatial flow underutilization field is calculated based on the OFDMA RU size.
EFFECT: improvement of spectral efficiency and reliability of communication line.
