In this paper, we consider the implementation of different Zadoff–Chu sequences to different modulation levels in communication systems with multiple modulation levels. The base station of the system can dynamically estimate the number of users in each modulation level by detecting the Zadoff–Chu sequences it receives. The base station then calculates the throughput of each modulation level and determines if any modulation level is saturated. If a modulation level is saturated, then the base station implements an additional mechanism on the users in the modulation level with the largest throughput. This mechanism makes users enter a waiting period before allowing further data transmissions so as to mitigate or reduce the base station load to accomplish the tasks and functions of the self-organizing network.
