If you have to go around then you do your lost comm procedures, ie squawk 7600. The reason we squawk 7600 is to ALERT ATC that we are no comm. They should then expect a traffic pattern to return to land while they clear the area. They are not going to keep funneling traffic to the airport with a 7600 on a go-around. This should be no different than losing comm on the arrival. Squawk 7600, proceed to a fix and begin an approach at your ETA like we have all learned before.
