Methods, systems, and devices for wireless communications are described. A shared channel may include a set of tones carrying multiple types of control information multiplexed together. A wireless device may perform a tone classification method to determine individual subsets of tones from the set of tones for each type of control information to extract each type of control information. The wireless device may determine multiple subsets of tones correspond to multiple types of control information simultaneously based on different extraction parameters. For example, the wireless device may determine a total number of tones in a set of tones, a distance between any given two tones in the set of tones, an offset value, or any combination thereof for the extraction parameters. The wireless device may then use these extraction parameters to determine or extract two or more subsets of tones for two or more corresponding types of control information.
