The Six Nations sides, along with Japan and Fiji, are set to feature in an eight-team tournament which will replace this year's autumn internationals, the BBC reports.
The tournament is scheduled to begin on November 14, two weeks after the completion of the Six Nations Championship that was postponed by the COVID-19 outbreak in March.
The report says England are likely to be in a four-team pool, alongside Wales, Ireland and Fiji, while Scotland, France, Italy and Japan will make up the other group.
After playing each other once, the teams would face their correspondingly ranked side in the other pool on the final weekend.
The tournament would be staged on four consecutive weekends until December 5, in line with the temporary international window proposed by the World Rugby last week.
