Revised – in principle. The commenter asks to clarify the sentence describing the OBO management. The related sentence has been modified:”… an HE STA shall initialize its OBO counter to a random integer value in the range of 0 and OCW.” 6005 The OCWmin value use for UL MU OFDMA random access is not clearly defined.

The commenter asks to clarify the OCWmin value and its usage.
