Backoff techniques for transitioning between single-user and multi-user modes

A method for wireless communication by a Base Station (BS) comprising:

• detecting that at least one Station (STA) has data to transmit on a medium;
• attempting to access the medium based on a first set of parameters to transmit a trigger frame to the at least one STA, the trigger frame scheduling resources for transmitting the data in a Multi-User (MU) mode,
• wherein one or more parameters of the first set of parameters are different from one or more parameters of a second set of parameters for attempting to access the medium in a Single-User (SU) mode and one or more parameters of a third set of parameters for attempting to access the medium in the MU mode.
