The types of committed availability may include a first type that is non-cancelable and a second type that is cancelable. The second availability schedule may be the second type. The wireless station may be further configured to transmit, to a second peer wireless station of the plurality of peer wireless stations, a third availability schedule where the third availability schedule may be the first type.
