In its 5G roadmap, the CEPT highlights the need to assess the technical conditions for the 900 MHz and 1800 MHz, with the goal to ensure suitability for 5G use and when applicable Active Antenna Systems (AAS). This Report assessed the suitability of the current ECC Decision (06)13 [1] regulatory framework for the possible future usage of: 900 MHz band for 5G non-AAS technology including SUL mode of operation. AAS technology is not considered for the 900MHz band in this Report; 1800 MHz band for 5G (AAS and non AAS) including SUL mode of operation; 1800 MHz band for LTE-AAS. The compatibility of such new technologies with current systems listed in the annexes 1 and 2 of the ECC Decision (06) 13 (GSM, UMTS, LTE, WiMAX and IoT cellular technologies) and adjacent band systems in 900/1800MHz bands have been evaluated in this Report and confirmed to be possible on similar basis as those concluded for LTE non-AAS in CEPT Report 40 [2], 41 [3] and 42 [4] and in ECC Report 266 [5]. The development of this Report followed the methodology used in previous ECC and CEPT reports and in particular CEPT Reports 40 and41. It also accounted for the development of Active antenna systems support for both LTE and 5G NR BSs. For the purpose of this report, Active Antenna System Technology for the BS will be referred to as AAS (LTE/NR) provided this technology is defined for LTE and for NR BSs and the related characteristics of both systems are generally aligned. AAS technology applies only to the BS side and not to the UE. This report does not consider or propose a Block Edge Mask (BEM) approach to technical harmonisation for 900/1800MHz band. In light with the results of the compatibility analyses, the report recommended updated ECC regulatory framework based on reference to ETSI harmonised standard of 5G (AAS and non-AAS) including SUL mode of operation and ETSI harmonised standard of LTE-AAS.
