The invention is directed to establishing a channel between an access point (AP) and a contaminating UE. An exemplary method comprises: detecting, by an AP, a contaminating UE, wherein the contaminating UE interferes with communication between the AP and other UEs in communication with the AP; and transmitting, by the AP, data to the contaminating UE on a first channel associated with a data frame, wherein the data frame comprises a downlink (DL) part, an uplink (UL) part, and a header.
