Abstract
In this letter, we propose a mathematical model of variable-length payloads transmitted in EDCA and transmitted using MU-MIMO. Assuming fixed-length or the use of mean value of payload length leads to discordant results while calculating the total payload length of variable-length frames transmitted within a fixed duration. Using the proposed model results in accurate results (less than 3% relative errors) for total payload length under variable-length traffic.
