Device-To-Device Assisted Video Transmission [PDF]

2013 20th International Packet Video Workshop, 2013
To increase spectrum efficiency, researchers envision a device-to-device (D2D) communication system in which a closely located mobile device pair may share the same spectrum with a cellular user. By opportunistically choosing the frequency, the D2D pair may increase the spectrum efficiency in terms of data rate per Hertz, at the price of additional ...
