After checking in with Denver Approach;  we were given a descend from 13;000 to 11;000 feet.  As we began the descent;  we received a GPS Primary Lost message on the navigation display and the GPS accuracy went from HIGH to LOW.  We also received the alert message NAV ADS-B RPTG 1 (and 2) FAULT.  Turning onto the final approach course;  the GPS accuracy returned to HIGH; but the ADS-B Fault periodically returned.  We landed the aircraft without any other issues.  Denver stated that it may have something to do with the 5G network.
On descent via the TBARR3 arrival into Denver we experienced dual GPS failure and dual NAV ADS-B RPTG 1 and 2 FAULTS.We checked in with Denver approach and we were given a heading 070 degrees and clearance to descend from 13;000 to 11;000 ft.  Approach advised that several aircraft were reporting 5G navigation interference on arrival into DEN.  We then experienced DUAL GPS failure and dual NAV ADS-B RPTG FAULTS in systems 1 and 2.  It was an intermittent failure about every 30 seconds for about 2 minutes until it finally failed.  We were approximately 30 miles southwest of DEN at this time. We subsequently heard several other aircraft report the same anomalies.The aircraft was on autopilot and continued to descend and level at 11;000 feet normally. The weather was 3;000 broken; 500 scattered and 1 3/4 miles visibility. We planned to fly the CAT I ILS 35L.  I discussed the issue with the First Officer and decided to continue with our plan to fly the ILS approach.  We received vectors to final and flew an uneventful approach and landing.I'm reporting this because I'm not sure if it was related to the 5G bulletins we have received over the last week.There were no NOTAMs that indicated that 5G would be an issue.
Air carrier flight crew reported loss of GPS signal while in descent to Denver airport.
