Hi Randy,
In the IEEE802.15.4e, there are two attributes related with a cell, i.e. LinkOption and LinkType. LinkOption indicates TX, RX, Shared, or Timekeeping; and LinkType indicates Normal or Advertising. According to my understanding, if the attributes of a cell are set as LinkOption = TX and LinkType= ADVERTISING, then the cell can be used as Broadcast cell. Make sense?
ThanksQin

Randy
