when the MAC layer has data for transmission on the PHY layer, initiate delivery of the subsequent frame from the MAC layer to the PHY layer for transmission before the end of delivery of the first frame by the PHY layer, wherein the subsequent frame is transmitted using the RIFS interval.
17. The apparatus of claim 16 wherein the function to indicate the PHY layer as busy further prompts the apparatus to:
assert a PHY carrier sense signal.
18. The apparatus of claim 16 wherein the delivery of the frame from the MAC to the PHY layer further comprises:
indicating the delivery with a MAC transmit frame signal.
19. The apparatus of claim 16 wherein releasing the PHY layer includes the PHY layer placing a PHY carrier sense signal at a logic low.
