Reports in Barcelona claimed the 41-year-old had already held a meeting with club president Sandro Rosell, at which he outlined his future plans.
He will convey that message to the players when they reconvene for training on Friday ahead of Sunday's trip to Rayo Vallecano, and then - according to the Spanish press on Thursday evening - will hold a joint press conference alongside Rosell.
The press conference is reportedly due to start at 1200 local time (6pm HKT, 3.30pm IST).
Guardiola has operated on short-term deals throughout his time at the Barca helm and his latest deal expires in the summer.
But the manner of their defeat to Real Madrid last weekend - a loss which effectively saw them relinquish their La Liga title to Jose Mourinho's men - and the midweek exit to Chelsea in the Champions League semi-finals may prompt Guardiola to walk away after four trophy-laden years.
Speculation on Thursday morning suggested the former Spain and Barca midfielder was giving serious consideration to quitting.
Speaking after the game with Chelsea on Tuesday, Guardiola said: "I will speak with Tito [Vilanova, assistant manager] and see what we have to do.
"Right now, we need to talk more about the emotion of our players and how they recover because there are many players that have been playing a long time.
"We have to go to Rayo Vallecano [this weekend]. We are still Barca. We have to continue doing things as we usually do them.
"So we will talk to the president as well and we will talk about everything - the situation what happened in these days and of course we will take a decision because it is time to take a decision now."
His departure may prompt speculation he could be a contender to become the new England manager, but journalists understand that will not be the case.
Guardiola stepped up from Barca B manager to first-team boss in 2008 and has gone on to become the most successful coach in the club's illustrious history.
He has led the azulgrana to two Champions League crowns, three La Liga trophies, one Copa del Rey, three Supercopas, two UEFA Super Cups and two FIFA Club World Cups.
Meanwhile, midfielder Xavi could miss the rest of the season because of a calf muscle tear.
"After tests this morning revealed his left calf has a tear, Xavi will be out of action for the next 15 days," a statement on the club's website read.
