The launch in China will give the company access to about half the users of its Android operating system, the report said.
The search engine giant exited China in 2010, citing repeated hacking attempts, potential loss of intellectual property and persistent censorship.
Some of Google's web services remain blocked in China and the features will not be available in the foreseeable future, the report said.
Nevertheless, "it will be unclear until the last minute" whether the government will actually permit a launch.
Google was not immediately available to comment.
