The service outage based allocation problem explores variable rate transmission schemes and combines the concepts of ergodic capacity and capacity versus outage for fading channels. A service outage occurs when the transmission rate is below a given basic rate r o. The allocation problem is to maximize the expected rate subject to the average power constraint and the constraint that the outage probability is less than ε. A general class of probabilistic power allocation schemes is considered in this problem. In an M-parallel fading channel model, the optimum power allocation scheme is derived and is shown to be deterministic except at channel states of a boundary set. The resulting service outage average rate is between the outage capacity times 1 - ε and the ergodic capacity.
