Methods and a devices are provided is for receiving simultaneous downlink transmissions at a mobile station (STA). Information regarding whether endings of simultaneous data transmissions to the mobile station are to be aligned is transmitted to an access point (AP). The simultaneous data transmissions are between the AP and the STA over a pair of channels. Reception begins of a first data transmission, from the AP, on a first channel of the pair of channels. Reception begins of a second data transmission, from the AP, on a second channel of the pair of channels. The second data transmission overlaps at least a portion of the first data transmission. Reception of the second data transmission ends upon an end of the first data transmission when the information indicates that the endings of simultaneous downlink data transmissions are to be aligned.
