Abstract
A first communication device in a first WLAN determines a channel estimate of a communication channel between the first communication device and a second communication device in a second WLAN using measurements at the first communication device of a first transmission between the second communication device and a third communication device in the second WLAN. The first communication device generates a PPDU for transmission to a fourth communication device in the first WLAN, including: determining, using the channel estimate, a precoder matrix to use for transmitting the PPDU in the first WLAN, and generating the PPDU using the precoder matrix so that interference at the second communication device in the second WLAN caused by transmission of the PPDU by the first communication device in the first WLAN is reduced. The first communication device transmits the PPDU to the fourth communication device in the first WLAN as a directional second transmission.
