摘要： For example, a non Access Point (AP) (non-AP) station (STA) may be configured to operate in a 40 Megahertz (MHz) operating mode, as a 40 MHz operating non-AP STA, which supports a 40 MHz operating channel width. For example, the 40 MHz operating non-AP STA may be capable to process allocation information from an AP to identify a Resource Unit (RU) or Multiple RU (MRU) (RU/MRU) allocated to the 40 MHz operating non-AP STA within the 40 MHz operating channel width; and to communicate data over the RU/MRU allocated to the 40 MHz operating non-AP STA as part of a wider bandwidth Orthogonal Frequency Division Multiple Access (OFDMA) transmission over a channel bandwidth of at least 80 MHz.
