The RFL is targeting a possible March return for clubs in the Championship and League One.
They say even though the government have said they will not be considering allowing crowds into games until at least April, the hope is the game can return before then.
Not having crowds was a big reason why they did not return in 2020. Despite this, there is a shared desire to return before crowds can come back.
Further discussions will take place at a forum between Championship and League One clubs next month.
The RFL will also liase with the Department for Culture, Media and Sport regarding the roadmap to get the sport back at that level.
Simon Johnson, the RFL Chair, said: “As we reflect on the Coral Challenge Cup Final, it is important that we continue to work with the clubs outside the Betfred Super League who have now gone almost seven months without any competitive action.
“The recent announcement that spectators would not be permitted to return to sport was a blow to these clubs, as it was to those in the Betfred Super League, as the return of spectators was key to the plans for the resumption of the Betfred Championship and League 1 competitions as soon as possible this winter.
“At the moment, we are led to believe crowds will not return until April. But as we have seen, these things can change – and with the Our League app, we do have the ability to provide coverage of matches direct to supporters even when crowds are not permitted in the grounds.
“It is difficult to come up with firm fixture plans given that ongoing uncertainty, but we want to give our clubs and supporters an idea of what might be possible in 2021.
“We of course face challenges, but the mood at the recent meeting was one of defiance and also excitement at the prospect of their 2021 return.”
