Enabling technologies for beyond TD-LTE-Advanced and 5G wireless communications

TD-LTE-Advanced was accepted as one of the 4G global standards by ITU in 2012. In 2013, Chinese government issued 4G TD-LTE licenses to all 3 Chinese operators. Now, more than 1/3 of the global 4G equipments and users are using TD-LTE-Advanced technology. Simultaneously, research toward 5G is one of the most attractive topics of mobile communication industry. The 3GPP has launched several workshops to discuss further enhancement on LTE-Advanced in R12 and R13. ITU has prepared reports, the IMT.vision and IMT.trend, for discussing future development of IMT. Now requirements on 5G have been agreed globally.
