A method, apparatus and computer program for providing a frame based access (FBA) for a wireless communication system such as a WLAN is disclosed. An FBA frame 412 to be provided to one or more stations (STAs) 434, 436, 438 indicating initiation of a multi-user transmission opportunity (TXOP) comprises an indication of an allocation of transmission resources and an access type for the FBA, comprising for example, at least one of orthogonal frequency-division multiple access (OFDMA), multi-channel OFDMA, or Time division multiple access (TDMA). The FBA frame may be transmitted in a beacon or at a predetermined time after a beacon. The FBA frame may contain an indication of MIMO mode. Legacy STAs interpret the frame as a long transmission and may enter low power mode. |
