It sounds like you're using manifest_version 2, which means you can just add path-to-jquery.js to the background.scripts array.

"background": {
    "scripts": ["jquery.js", "background.js"]
}

Those files all get loaded in an generated page together, so they access the same global scope—which means you can use jQuery as usual.
