You haven't really defined what kind of "other signal" you set up. ath10k sets/enables dynamic_bw wmi parameter in ath10k_start(). From what I know dynamic_bw does enable fw/hw to downgrade traffic from 80MHz to 40MHz in case there's other 802.11 traffic on the subband happening at least on 10.1.467 - not sure about non-802.11 traffic. I suppose newer firmware revisions do that too. I'm not sure about 999.999.0.636 though.
