1. A method for communicating in a wireless local area network (WLAN) via a communication channel that includes a plurality of channel segments, the method comprising:
selecting, at a first communication device, respective sets of medium access control (MAC) layer data units for transmission via respective channel segments, among the plurality of channel segments, to one or more second communication devices, including selecting at least i) a first set of MAC layer data units for transmission in a first channel segment and ii) a second set of MAC layer data units for transmission in a second channel segment, wherein the first channel segment and the second channel segment are non-overlapping frequency segments;
generating, at the first communication device, respective aggregate MAC layer data units to include the respective sets of MAC layer data units, including generating i) a first aggregate MAC layer data unit to include the first set of MAC layer data units and ii) a second aggregate MAC layer data unit to include the second set of MAC layer data units;
generating, at the first communication device, respective physical (PHY) layer data units to include the respective aggregate MAC layer data units, including generating i) a first PHY layer data unit to include the first aggregate MAC layer data unit and ii) a second PHY layer data unit to include the second aggregate MAC layer data unit; and
transmitting, from the first communication device, the respective PHY layer data units to the one or more second communication devices, including transmitting i) the first PHY layer data unit in the first channel segment and ii) the second PHY layer data unit in the second channel segment, wherein transmission of the first PHY layer data unit in the first channel segment overlaps in time with transmission of the second PHY layer data unit in the second channel segment.
