1 Scope p. 6

The present document is a technical report for Work Item on New Radio (NR) Access Technology, covering introduction of lower 6GHz NR unlicensed operation for Europe (NR_6GHz_unlic_EU) and in the 5925-7125 MHz range for other regions (NR_6GHz_unlic_full).

2 References p. 6

4 Background p. 7

Administrations in Europe have had unlicensed operation in the range 5925 to 6425 MHz for consultation. The result of this consultation is that at the November 2020 meeting the ECC with ECC Decision (20)01 "on the harmonised use of the frequency bands 5945 to 6425 MHz for the implementation of Wireless Access Systems including Radio Local Area Networks (WAS/RLANs)" approved unlicensed operation in the range 5945 to 6425 MHz. This initiated this TR which has later been expanded to also include NR unlicensed operation in the 6 GHz band for other regions.

NR-Unlicensed is standardized in Rel-16 with the definition of band n96 covering the spectrum range 5925-7125 MHz which is currently applicable in the USA only subject to FCC Report and Order FCC 20-51. For Rel-17 3GPP WG4 is tasked to also enable unlicensed operation in the range 5945 to 6425 MHz for European deployments and in the 5925-7125 MHz range for other regions.
