The two basic ideas behind LTE-TDD are that more data comes in to a phone than goes out from a phone, and that transmissions to and from the phone should share the same frequency.

On November 6, KT announced that it succeeded in demonstrating the world’s first TM9 based two-way simultaneous CoMP technology in association with Ericsson. 

CoMP is one of the main technologies for LTE-A, allowing mutual interlocking among base stations to make sure cellphones can receive the best antenna signals. It was limited to one-way operations until now, either as an uplink or downlink. KT explained that it minimized interruptions from nearby cell towers by sending demodulated signals or recovering signals from one base station changed per cellphone device. 

With this information it is possible to handle the drastically-increased data usage from servicing mass storage video streaming, uploading photos and videos on SNS, and long-term storage of data on cloud servers. The goal is to commercialize the technology by early 2014. 

KT explained, “This demonstration was held on November 6 at the Ericsson headquarters in Sweden with major executives from both companies participating, and confirmed that the uploading and downloading speed on cellphones near the base stations have increased 20% from the original speed.”
