Patent ID: 7773639

Claim:
A method for synchronizing packet production and receipt from a digital signal processor (DSP) with polled transmission opportunities in an IEEE 802.11(e) network, the method comprising: producing a packet via the DSP; transmitting the packet from the DSP to a transmission device at a time that is substantially synchronized with a next polled transmission opportunity granted by an access point in an IEEE 802.11(e) network; time stamping the arrival of the packet at the transmission device; transmitting the packet from the transmission device, time stamping the transmission of the packet by the transmission device; computing the wait time of the packet in the transmission device as the difference between the arrival time stamp and the transmission time stamp; comparing the wait time to a wait time threshold; determining a shift time based on the computed wait time upon the computed wait time being greater than the wait time threshold; and transmitting the shift time to the DSP in a synchronization request.
