To　satisfy　differentiated　service　requirements　of　delay-sensitive　and　computing-intensive　tasks　in　satellite　communication　networks,　we　propose　a　cache-assisted　low-latency　content　distribution　scheme　in　multi-cell　multi-carrier　non-orthogonal　multiple　access　(MCMC-NOMA)-based　satellite-edgeterminal　cooperation　environments.　In　the　paper,　a　delay　minimization　problem　is　formulated　to　achieve　optimal　content　distribution　by　jointly　optimizing　the　allocation　of　subchannels　and　transmit　power,　which　is　decomposed　and　solved　in　each　slot　by　using　many-to-one　matching　and　successive　convex　approximation,　respectively.　Simulation　results　show　that　the　proposed　model　significantly　improve　network　latency　and　content　distribution　in　comparison　to　its　existing　counterparts　in　cloud-edgeterminal　cooperation　networks.
