Sec. 90.1005  Competitive bidding mechanisms.

    (a) Sequencing. The Commission will establish and may vary the 
sequence in which 220 MHz geographic area licenses are auctioned.
    (b) Grouping. The Commission will determine which licenses will be 
auctioned simultaneously or in combination.
    (c) Minimum bid increments. The Commission may, by public 
announcement before or during an auction, require minimum bid increments 
in dollar or percentage terms.
    (d) Stopping rules. The Commission may establish stopping rules 
before or during an auction in order to terminate the auction within a 
reasonable time.
    (e) Activity rules. The Commission may establish activity rules 
which require a minimum amount of bidding activity. In the event that 
the Commission establishes an activity rule in connection with a 
simultaneous multiple round auction, each bidder may request waivers of 
such rule during the auction. The Commission may, by public announcement 
either before or during the auction, specify or vary the number of 
waivers available to each bidder.
