Sharing of ARQ slots in Gilbert-Elliot channels

This letter treats the problem of m transmission slots sharing a pool of n automatic repeat request slots. Two cases are treated. In one, these m slots belong to the same base station-terminal pair, i.e., a frequency-division multiplexing channel. In the other, they are used by m different base station-terminal pairs, i.e., a time-division multiplexing channel. The smallest n to satisfy loss and delay requirement is determined.
