1. A method of data transmission in a wireless network, the method comprising:
transmitting a frame from a first affiliated wireless access point (AP) of a multi-band wireless AP for receipt by a wireless station (STA), wherein the transmitting performed over a first wireless link, and the frame solicits a response frame;
determining that a second affiliated wireless AP of the multi-band wireless AP is scheduled to transmit a trigger frame to the wireless STA over a second wireless link, the trigger frame comprising a carrier sense (CS) required field having a predetermined value; and
transmitting the trigger frame from the second affiliated wireless AP for receipt by the wireless STA over the second wireless link, wherein the response frame solicited by the frame is scheduled for transmission after the predetermined value has expired following an end of a physical layer conformance procedure (PLCP) protocol data units (PPDUs) which contains the trigger frame.
