Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a first device may transmit a signal to a second device including a number of error detection bits interleaved with a number of information bits. The second device may use the error detection bits to determine if the signal was received correctly, where each error detection bit may be associated with a set of information bits. The second device may progressively decode the signal and continuously perform an error detection calculation based on a first set of information bits associated with a first error detection bit. Based on the error detection calculation, the second device may calculate an expected error detection bit corresponding to the first error detection bit. The second device may compare the first error detection bit to the expected error detection bit. Other aspects and features are also claimed and described.

Abstract: 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.
