    in sync”

    indication comprising establishing a communication link for the anchor carrier before establishing any communication links for the secondary carriers, wherein the at least one “

    in sync”

    indication is derived based at least in part upon comparing one or more power control bits of each of the communication links for the anchor carrier and each secondary carrier with a threshold value within a period of time; and
