According to an article from The Register, a team from Stanford University has patented technology that could halve the bandwidth that a mobile provider needs.
Operating under the name Kumu Networks, they are showcasing tech which they claim would exactly double throughput. Radio equipment (such as mobile phones) would be able to send and receive on the same frequency through a process similar to noise-cancelling headphones; by knowing what a base station is transmitting it can cancel out the information from the very faint signal it receives.

So are they claiming double-throughput because you would still use two frequencies, but use them each full duplex?

No. They're claiming to double spectral the efficiency of a single frequency by allowing a radio to both transmit and receive on a singular frequency, without the local transmitter desensing the local receiver.
Of course it could use multiple carriers -- just as anything else could, from RF to Ethernet. That's a different issue.
