Embodiment Construction
[0025] Consider a satellite communication system with K beams, each beam has N users, resource scheduling is to divide all users (a total of K×N) into N groups, and each group contains K users from different beams. The basic idea of the resource scheduling algorithm is to select one user from each of the K beams, group the K users into a group, repeat N times in total, and set the frequency point f i (i∈[1,N]) is assigned to the user merged for the ith time. If the number of users in a certain beam is less than that of other groups, if it is found that the users in this beam have been grouped during grouping, this beam will be skipped. If there are many users in a certain beam, the extra users use frequency points on the reserved frequency band to transmit downlink signals.
[0026] Denote the central beam as beam 1 and number the other beams in spiral order outward from the central beam. use Record the unassigned users in beam k before the ith merging process (k∈[1,K],...
