Abstract:
1. A method for selective suppression of sidelobe signals using controlled signal cancellation, the method comprising: receiving an indication that a signal from a single user equipment (UE) is received at each of two or more access points (APs) over the same channel, wherein the relatively stronger power signal is received over a primary lobe of a communication beam of one of the APs and the relatively weaker power signal is received over a side lobe of a communication beam of another one of the APs; testing the efficacy of signal cancellation by turning signal cancellation on and off to measure the UE signals received at one of the APs; and if interference is lower when signal cancellation is turned on, applying said signal cancellation for continued communication with said UE to cancel side lobe signals and if interference is lower when signal cancellation is turned off, communicating with said UE without applying said signal cancellation.
