Patent ID: 7826429

Claim:
A system, comprising: a medium access controller to wirelessly communicate with a remote device under an 802.11n wireless standard, the medium access controller comprising: a processor to transmit frames to and receive frames from the remote device under a modulation standard using one or more target modules, the one or more target modules comprising a digital signal processor; a transmit and receive machine to process frames received wirelessly from the remote device; wherein: the digital signal processor sends a first hardware control signal to the transmit and receive machine when a receive envelope closes, wherein the closed receive envelope indicates an end of a received frame, wherein the hardware control signal is coupled between the digital signal processor and the transmit and receive machine; the transmit and receive machine starts an interval timer to denote a first time period; if the transmit and receive machine confirms that: the received frame is addressed to the medium access controller; and the received frame is without error; then, the transmit and receive machine initiates an acknowledge signal to be sent to the remote device by the processor at a second time period; wherein the duration between the second time period and the first time period is within a short inter-frame spacing interval of the modulation standard.
