As a high-throughput satellite resource allocation method, beam-hopping technology can flexibly configure on-board resources according to ground service requirements, thereby improving onboard resource utilization. In this paper, the beam-hopping technology is applied to the Low Earth Orbit(LEO) constellation scenario. In view of the two situations where the user's traffic is unknown and known a priori, the co-channel interference between beams is considered. Based on the iterative algorithm and convex optimization, a suitable low-orbit constellation is formulated. The two beam-hopping beam resource scheduling strategies can achieve higher system throughput compared with the traditional strategy, and bear better delay performance at the same time. They also adapt to the uneven distribution of user service requirements.
