Backoff snooze wake power consumption within single user, multiple user, multiple access, and/or MIMO wireless communications. If a communication (e.g., transmission) attempt fails (e.g., by a wireless station (STA), smart meter station (SMSTA), etc.), then a backoff snooze countdown may be performed before a subsequent communication is attempted. Also, if communication activity is detected on the communication medium, then such a backoff snooze countdown may be performed before monitoring the communication medium or a subsequent communication attempt is made. Such a backoff snooze countdown may be based on a codeword value (e.g., such as provided within a beacon received from an access point (AP)), and different respective backoff snooze countdowns may be made based on different respective codeword values. Such backoff snooze countdowns are performed outside of a restricted access window (RAW) in which only devices of a particular class (e.g., low-power, Z, etc.) have access to the communication medium.
