The present disclosure provides a method and an apparatus of resource sharing for D2D and cellular communications. The method may comprise: determining a cellular user set containing potential cellular users that may share resources with a D2D pair; and determining transmit power of the D2D pair on a frequency band of at least one cellular user in the cellular user set and transmit power of the at least one cellular user through maximizing throughput of the D2D pair with a quality of service (QoS) constraint and a power budget constraint of each of the potential cellular users and a transmit power constraint of the D2D pair. With embodiments of the present disclosure, it may provide a non-orthogonal resource sharing solution in which a D2D pair can reuse resources of the cellular users as more as possible while the QoS of all the cellular users are guaranteed, whereby the performance of the D2D user may be improved greatly.
