The hidden terminal problem with a specific two-network scenario, i.e., K = 2. This is the hidden terminal-based system model in MU-MIMO WLANs that we have considered, with the jth network reference client “I4”. Here, we have taken K=2 APs, out of which AP1 is the desired AP for “I4” whereas the remaining ith network AP2 is a hidden AP. Given K hidden APs, there are K APs interfering with the desired transmission at the jth network client “I4”
