In Rel-14 and Rel-16, RAN introduced a set of features under the umbrella of "LTE based 5G terrestrial broadcast" that, together with the corresponding enhancements in the core network, enable the deployment of a downlink-only dedicated broadcast network using 3GPP technologies.
A clear target spectrum for this technology is the portion of UHF spectrum allocated to broadcast systems (~470 - ~694/698MHz, depending on the region). The objective of this work item was to introduce the necessary features for LTE based 5G terrestrial broadcast to operate in the portion of UHF spectrum allocated to broadcast systems in different regions of the globe. For instance:
- For ITU region 1, a channelization of 8 MHz is used.
-
For ITU region 2, a channelization of 6 MHz is used.
- In some countries (e.g. North America), frequencies above 614 MHz are used by FDD (B71).
-
For ITU region 3, different channelizations (6/7/8 MHz) are used in different countries, for instance China and India are using 8 MHz.
- In China broadcast systems are using the spectrum ranges 470 - 702 MHz.
- In India broadcast systems are using the spectrum ranges 470 - 610 MHz and 614 - 698 MHz.
- For ITU region 1, requirements defined in ETSI EN 302 296 [3] and GE06 Agreement [5].
-
For ITU region 2:
- In United States, FCC Title 47 CFR 73.622 [6].
- In Brazil, ABNT NBR 15601 [7].
- For ITU region 3: in China, GB20600-2006 [8].
