Claim Text:
1. A method for interference process of an interference signal in an OFDM (Orthogonal Frequency Division Multiplexing) based wireless communication system, comprising: receiving an interference signal; performing time domain and frequency domain analyses on the interference signal to obtain interference characteristics of the interference signal; determining an interference category of the interference signal according to the interference characteristics of the interference signal; and performing interference process on the interference signal in view of the interference category of the interference signal, wherein performing interference process on the interference signal in view of the interference category of the interference signal further comprises: in response to determining that the interference category of the interference signal is avoidable interference, generating interference indication information according to frequency occupation of the interference signal in a wireless frequency band; sending the interference indication information to a resource scheduler in an upper layer of its protocol stack; transmitting the interference indication information to a mobile terminal through a downlink control channel; and instructing the mobile terminal to avoid frequencies having interference thereon when the resource scheduler allocates frequencies to the mobile terminal.
