We investigate memoryless multiple-access relay channels (MARCs) and establish the capacity of two semideterministic classes of such channels: MARCs with orthogonal receive components and state-decoupled MARCs. For both cases, the achievability and converse are proved using the noisy network coding lower bound and the cutset upper bound, respectively. Finally, the capacity of a MARC with additive Gaussian interference is quantified.
