Patent ID: 8630197

Claim:
A method for determining a data rate and a packet length for a data transmission in a wireless communication network, the method comprising: operating a wireless communication device within the wireless communication network to: initialize a starting value for a packet length and a data rate; determine an effective throughput (G) based on a measured value of a packet completion rate (PCR); determine a channel condition index based on the determined effective throughput; adjust the packet length based on the determined channel condition index; adjust the data rate based on the determined packet length; and transmit at least one data transmission using the adjusted packet length and the adjusted data rate; and wherein determining the channel condition index further comprises: calculating the channel condition index based on the current data rate; identifying the effective throughput (G) as a function of packet length (L) and the channel condition index (CCI); and finding a value of the channel condition index for which the function has the closest value to the effective throughput (G).
