BCCI Secretary Niranjan Shah told UNI phone from Rajkot that the tourney is likely to be held in January-February and is expected to feature Sri Lanka, who have already confirmed their participation and West Indies after they finish their tour of Pakistan.
The World Cup is to be held in the West Indies in March-April.
Meanwhile, the proposed tri-series in Singapore and Malaysia will tentatively be staged from September 15 to 29, Shah said, adding that the series would have seven matches which would require around 15 days.
The series, part of the BCCI's scheduled off-shore neutral venue ties, will feature India and Australia while confirmation is awaited from the West Indies.
''The West Indies Board officials have sought two or three more days' grace period from us to confirm whether they can take part after talking to their players,'' Shah explained.
''A final decision would be taken before the end of this week.
There are other teams who are willing to take the place of the West Indies in case they are unable to come,'' Shah added.
