Method, apparatus, and communication system for adaptive frequency domain resource configuration

摘要

Disclosed are an adaptive frequency domain resource configuration method, an apparatus, and a communications system. The method includes: receiving, by a receiving apparatus, a pilot signal transmitted by a transmitting apparatus; and feeding back channel information of a channel for transmitting the pilot signal to the transmitting apparatus by measuring the pilot signal, so that the transmitting apparatus divides a bandwidth frequency of the transmitting apparatus according to the channel information. The receiving apparatus can feed back the channel information to the transmitting apparatus according to the received pilot signal, so that the transmitting apparatus can divide the bandwidth frequency according to channel quality, and adaptive adjustment can be performed on a frequency domain resource of each subcarriers according to the channel information fed back by the receiving apparatus, so that the frequency efficiency of the system can be improved, and the performance of the communications system can be ensured.
