Claim:
1. A method of resource sharing for device-to-device (D2D) and cellular communications, comprising: 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, wherein the determining the cellular user set comprises: for each of scheduled cellular users, performing a feasibility checking to find cellular users whose QoS can be guaranteed without resource sharing, and wherein the performing the feasibility checking comprises: determining whether power budget of each of the scheduled cellular users satisfy: wherein ρ
