Rapporteur:  Mr. Liu, Liehai

At the ITU World Radio communication Conference in 2015 (WRC-15), the frequency band 1427 - 1518 MHz (hereafter, L-band) was identified for International Mobile Telecommunications (IMT). In accordance with this outcome at WRC-15, ITU-R Working Party 5D (WP 5D) initiated to revise Recommendation ITU-R M.1036 "Frequency arrangements for implementation of the terrestrial component of International Mobile Telecommunications (IMT) in the bands identified for IMT in the Radio Regulations". For this revision, it has been proposed to include a new TDD arrangement.
In 3GPP, the Study Item required transmission restrictions of UE and BS to meet the unwanted emission limit (- 62dBW/27MHz with UE transmit power of 15dBm; -72dBw/27MHz at the BS antenna connector) for protection of the Earth Exploration-Satellite Service (EESS) was investigated. Also, MSS protection has been taking into account, for the BS case and EU case.
According to results of the studies, the implementation of TDD arrangement in the L-band is a realistic option while achieving the protection of the EESS and MSS.
