Background The access network device may employ adaptive modulation and coding (adaptive modulation and coding, AMC) techniques to obtain a better throughput rate. AMC refers to adjusting a reference modulation coding scheme (modulation and coding scheme, MCS) according to Acknowledgement (ACK)/negative acknowledgement (negative acknowledge, NACK) fed back by a terminal device, where the adjusted MCS is the final MCS. Wherein, the reference MCS is determined according to the channel quality indication (channel quality indicator, CQI) reported by the terminal equipment. In satellite systems, AMC may also be used by satellites in order to obtain better throughput. To enable satellites to service all the wave positions of a coverage area, beam Hopping (BH) technology is employed. The beam hopping technique requires that the isolation of-10 dB be satisfied between any two co-frequency beams on the satellite side, and the signal-to-interference-and-noise ratio (Signal to Interference plus Noise Ratio, SINR) of the received signal still can fluctuate widely in different beam hopping periods (Beam Hopping Period, BHP) of the terminal equipment, so that the AMC is in a low-efficiency state due to the fluctuation of the SINR in a large range, and the communication efficiency is reduced.
