Airport; Procedure
Initiated takeoff. Aircraft approaching to land on adjacent runway initiated Go-Around. Our relative position to the Go-Around aircraft caused Tower to cancel our takeoff clearance. I was Pilot Flying (PF) though my hands were not on the thrust levers due SOP. I was pretty sure I heard the Cancel Takeoff clearance; but the Captain did not respond. I said; 'I'm pretty sure that call was for us.' The Captain immediately called Tower requesting 'Who was that for?' to which they replied with our flight number. He then initiated an RTO. We both believe our speed was about 105 knots at initiation. The RTO braking feature worked perfectly and by the time I thought to make my first call out (having to revert to Pilot Monitoring (PM) rather suddenly); we were below 60 knots. My thoughts at that time; seeing we had thousands of feet of runway remaining...was to disarm the auto brakes so the stop would not be so uncomfortable to the passengers but I remembered that is against policy. So I accepted the uncomfortable; 3;000 psi braked stop.... Our jumpseater...used the [performance computer] to determine a brake cooling time (40 minutes) as we returned to the gate for cooling and additional fuel.
