Narrative:
Deviation from SID track. I was pilot monitoring during climb out on the lgl 3B at cdg. We departed with minimum spacing behind a 777-300ER. With a weak to negligible crosswind component in light winds; we got into strong wake turbulence. Captain/pilot flying altered our flight path in an effort to climb above and upwind of the wake. We were given a frequency change to departure control; at which point we were in and out of the wake turbulence. We were unable to fly over PG264. Due to frequency congestion and my concern with monitoring the flight path; airspeed and cleaning up the aircraft; I failed to check in with departure in a timely manner. Weather was VMC with scattered small tcus and I observed no apparent traffic conflicts. As we began acceleration to clean up; ATC cleared us direct lesga. Remainder of flight was uneventful.task saturation and frequency congestion. We could have been more proactive; i.e. Requesting increased spacing above standard before commencing takeoff. I also could have been more assertive with pilot-to-pilot; as well as ATC communication; and asked the pilot flying if he would like SID track relief or just requested it from departure control.
