description Disclosed are an indication method, system and device for a dynamic idle frequency. After a TD-LTE network side determines a usable idle frequency band, the idle frequency band is used as an auxiliary carrier, wherein the idle frequency band includes frequencies occupied by other narrowband systems; then a main carrier sends auxiliary carrier configuration information, which includes an auxiliary carrier center frequency point and bandwidth, to a terminal, wherein the auxiliary carrier center frequency point is a center frequency point of the usable idle frequency band and the auxiliary carrier bandwidth is a non-LTE-standard bandwidth; and at last, auxiliary carrier resources are scheduled for the terminal and scheduling information is notified to the terminal through the main carrier, wherein the scheduling information is capable of indicating all resource blocks of the non-standard-bandwidth auxiliary carrier and narrowband interference signals in an auxiliary carrier frequency range can be avoided. The TD-LTE is capable of using an idle frequency band with a non-LTE-standard width as an auxiliary carrier and capable of scheduling and indicating all resource blocks capable of avoiding the narrowband interference signals on the auxiliary carrier so as to allocate to the terminal.
