1. A method for communicating in a wireless communication network, the method comprising:
generating, at a first communication device, a multi-user (MU) physical layer (PHY) data unit having independent data for multiple second communication devices; generating, at the first communication device, respective control frames corresponding to at least some of the second communication devices, wherein the respective control frames are configured to prompt the at least some of the second communication devices to transmit an orthogonal frequency division multiple access (OFDMA) PHY data unit to acknowledge that the at least some of the second communication devices received the MU PHY data unit; transmitting, with the first communication device, the MU PHY data unit to the multiple second communication devices; transmitting, with the first communication device, the respective control frames to the multiple second communication devices; receiving, at the first communication device, the OFDMA PHY data unit from the at least some of the second communication devices, the OFDMA PHY data unit corresponding to an acknowledgment of the single MU PHY data unit by the at least some of the second communication devices; and processing, at the first communication device, the OFDMA PHY data unit to determine that the at least some of the multiple second communication devices received the single MU PHY data unit. |
