TDD Spectrum White Paper-June 2019 Update from GTI

TDD Spectrum:

To provide information and suggestions for facilitating the efficient utilisation and fast deployment of TD-LTE globally and smooth evolution to 5G NR, this white paper summarises the advantages of TDD spectrum, driving forces of rapid TDD network deployment and fast TDD spectrum allocation for 5G.Further, spectrum-related issues on TDD applications and network deployment are discussed and corresponding solutions for commercial deployment are presented.

Also, this white paper identifies major TDD market trends as follows:

• TDD spectrum is becoming more and more important with new values: the rapid development of new technologies such as massive MIMO and mature industry ecosystem and smooth evolution to 5G
• As the demand for unlimited packages and wireless home broadband grows, TDD network deployment is accelerating around the world to effectively resolve capacity and experience issues with evolution capabilities.
• TDD spectrum allocation has become a majorconcern of national regulators. TDD spectrum (for example, 2.3 GHz, 2.6 GHz, 3.5 GHz, and 4.8 GHz) allocation is accelerating, not only to meet the network requirements in the short term, but also to meet the strategic requirements for telecommunication industry development in the long term.

To facilitate fast TD-LTE and NR deployment, this white paper also provides the following recommendations and suggestions for operators, standardisation organisations, and regulators:

• Accelerate the allocation of TDD spectrum (especially 2.3 GHz, 2.6 GHz, 3.5 GHz, and 4.8 GHz bands) to break through the 4G traffic bottleneck and quickly evolveto 5G
• Guide reasonable spectrum pricing and issue nationwide exclusive licenses with a 15-to 20-year validity period. This plays a fundamental role in maintaining the flourishing development of the mobile industry while advancing rapid deployment of wireless infrastructure.
• Contiguous TDD spectrum assignments employing wide blocks is beneficial for improving mobile broadband experience and spectrum efficiency of networks. 2.6GHz(band 41) is recommended for contiguous TDD spectrum allocation leveraging the large bandwidth
• New spectrum assignments must be technology and service neutral
• Synchronized operation amongst TDD networks is recommended for best spectrum utilization
• Speed up the reclaiming of TDD spectrum still occupied by old technologies or satellitesand re-assign these resourcesto improve spectral efficiency and contribute to economic development.
