The present disclosure includes systems and techniques relating to interference measurement pilot tones in communication systems. In some implementations, a method includes identifying, by a transmitting device, a pilot pattern for transmission in a plurality of orthogonal frequency-division multiplexing (OFDM) symbols over a wireless local area network (WLAN) channel, the pilot pattern including an interference measurement pilot tone, wherein the interference measurement pilot tone is located at a specified frequency and time location in the plurality of OFDM symbols, the interference measurement pilot tone including a null tone that facilitates a receiving device to measure interference; and transmitting, by the transmitting device, the pilot pattern in the plurality of OFDM symbols over the WLAN channel. The pilot pattern can further include a regular, nonzero pilot tone that facilitates the receiving device to measure a frequency drift or a phase noise.
