Method and network equipment for reusing resources of relay system

The invention discloses a method and network equipment for reusing resources of a relay system. The method comprises the following steps: determining the interference ratio and the signal to interference and noise ratio of user equipment in the second time slot in a sector; determining whether the user equipment can be reused or not according to the interference ratio and the signal to interference and noise ratio of the user equipment; and distributing the total spectrum resources of the second time slot in the sector respectively to the user equipment which can be reused, direct transfer use equipment which can not be reused and relay user equipment which can not be reused to be used, wherein the spectrum resources distributed to the user equipment which can be reused can be reused by the direct transfer use equipment which can be reused and the relay user equipment which can be reused. The network equipment comprises a first determination module, a second determination module and a first distribution module. The method and the network equipment can effectively avoid interference and improve the signal to interference and noise ratio of the user equipment by dividing the user equipment into the user equipment which can be reused and the user equipment which can not be reused, thus increasing the throughput of the whole system.
