Patent ID: 7688855

Claim:
A computer implemented method for sending a multi-rate multi-response multi-receiver aggregate frame comprising at least one data frame and at least one multi-receiver multi-response aggregate frame, the method comprising: initiating transmission of the multi-rate multi-response multi-receiver aggregate frame; transmitting at least one data frame embedded in the multi-rate, multi-response, multi-receiver aggregate frame until encountering a multi-receiver multi-response aggregate frame; transmitting the multi-receiver multi-response aggregate frame embedded within the multi-rate multi-receiver multi-response aggregate frame; suspending the transmission of the multi-rate multi-response multi-receiver aggregate frame, responsive to transmitting the multi-receiver multi-response aggregate frame, immediately after sending the multi-receiver multi-response aggregate frame embedded within the multi-rate multi-response multi-receiver aggregate before sending a next frame contained within the multi-rate multi-response multi-receiver aggregate frame; waiting for a predetermined time period after suspending the transmission; and resuming transmission of the multi-rate multi-response multi-receiver aggregate frame after waiting the predetermined time period; wherein resuming transmission comprises sending the next frame contained within the multi-rate, multi-response, multi-receiver aggregate frame.
