Abstract
A method performed by a STA may comprise receiving, from an access point, a RTS frame having a duration field and transmitting, to the AP, in response to receiving the RTS frame, a CTS frame. The method may further comprise receiving, from the AP, data of a MU data unit addressed to the STA and another STA and, in response, transmitting an ACK frame, to the AP. The data may be received by the STA on a subset of sub-carrier frequencies of which the MU data unit spans and the MU data unit and the ACK frame may be transmitted within a duration indicated by the duration field.
