Summary:Embodiments of the present invention provide a method and an apparatus for downlink and uplink compression of a nonstandard bandwidth of an LTE system. A base station filters a baseband signal by using a filter whose bandwidth is a nonstandard bandwidth of LTE, and filters out a signal outside the nonstandard bandwidth of LTE; and the base station may send a signal to a terminal by using the nonstandard bandwidth of LTE that can be provided by an operator. For example, the operator can provide only an LTE nonstandard bandwidth of 3M that falls within 1-4M, and a standard bandwidth of the LTE is 5M, and therefore, the filter needs to filter out signals within bandwidths 0-1M and 4-5M. During final sending, the base station uses the LTE nonstandard bandwidth of 3M; during receiving, the terminal uses the LTE standard bandwidth of 5M for receiving; and the base station has no signal within bandwidths 0-1M and 4-5M. The base station also needs to send the nonstandard bandwidth of the LTE system to the terminal, so that the terminal sends data to the base station according to the nonstandard bandwidth of the LTE system.
