Detailed Description

Dummy Multi User Scheduler used to test OFDMA ack sequences.

This Multi User Scheduler returns SU_TX until the simulation time reaches 1.5 seconds (when all BA agreements have been established). Afterwards, it cycles through UL_MU_TX (with a BSRP Trigger Frame), UL_MU_TX (with a Basic Trigger Frame) and DL_MU_TX. This scheduler requires that 4 stations are associated with the AP.
