Guard Band-Based Resource Sharing for Device-to-Device Communications Underlying Cellular Network
The performance of device-to-device (D2D) communication in a cellular network depends on the resource sharing between D2D links and cellular users. Existing researches on resource sharing mainly focus on power control between the D2D users and cellular users that operate in the same frequency band....
