  We study the quantum coherence and its distribution of N-partite GHZ and W
states of bosonic fields in the noninertial frames with arbitrary number of
acceleration observers. We find that the coherence of both GHZ and W state
reduces with accelerations and freezes in the limit of infinite accelerations.
The freezing value of coherence depends on the number of accelerated observers.
The coherence of N-partite GHZ state is genuinely global and no coherence
exists in any subsystems. For the N-partite W state, however, the coherence is
essentially bipartite types, and the total coherence is equal to the sum of
coherence of all the bipartite subsystems.
