Brazil Releases Amended Requirements for Access Terminal Stations
National telecommunication agency of Brazil (ANATEL) published Act № 10002 on November 29, 2021. The Act updates Act №3151 on technical requirements for conformity assessment procedure for Access Terminal Stations. ANATEL adds requirements to the Cat NB2 standard (NB-IoT). In addition, it introduces the following new requirements and test methods applicable to 5G NR technology:
1. Frequency range 1 non-standalone intra-band non-contiguous SMP:
EU Maximum Output Power reduction for Intra-Band Non-Contiguous EN-DC
General spurious emissions for Intra-band non-contiguous EN-DC
2. Frequency range 1 non-standalone inter-band SMP:
Adjacent channel leakage ratio for inter-band EN-DC within FR1
3. Frequency range 2 standalone and SMP (test methods according to ETSI TS 138 521-2 V16.6.0 (2021-02)):
UE maximum output power
Configured transmitted power
Minimum output power
General ON/OFF time mask
Error Vector Magnitude
Spectrum emission mask
Adjacent channel leakage ratio
Transmitter Spurious emissions
4. Frequency range 2 standalone inter-band SMP (test methods according to ETSI TS 138 521-3 V16.6.0 (2021-01)):
UE Maximum Output Power for Inter-Band EN-DC including FR2
Configured Output Power for Inter-Band EN-DC including FR2
EU Minimum Output Power for EN-DC Inter-band EN-DC including FR2
Frequency Error for inter-band EN-DC including FR2.
Occupied bandwidth for Inter-Band EN-DC including FR2 (2 CCs)
Spectrum emissions mask for Inter-band EN-DC including FR2 (2 CCs)
Adjacent channel leakage ratio for Inter-band EN-DC including FR2 (2 CCs)
General Spurious Emissions for Inter-band including FR2 (2 CCs)
Please, note that if the standard tests are not intended for the “LTE anchor agnostic”, it is possible to use approach with anchoring in 3 (three) LTE bands (lower frequency band, intermediate frequency band and higher frequency band), performing the combination of the 3 LTE bands with all the NR 5G bands.
Furthermore, ANATEL updates the following standards for application:
ETSI TS 136 521-1 V16.8.1 (2021-06) - LTE; Evolved Universal Terrestrial Radio Access (E-UTRA); User Equipment (UE) conformance specification; Radio transmission and reception; Part 1: Conformance testing (3GPP TS 36.521-1 version 16.8.1 Release 16);
ETSI TS 138 521-1 V16.6.0 (2021-02) - 5G; NR; User Equipment (UE) conformance specification; Radio transmission and reception; Part 1: Range 1 standalone (3GPP TS 38.521-1 version 16.6.0 Release 16);
ETSI TS 138 521-3 V16.6.0 (2021-01) - 5G; NR; User Equipment (UE) conformance specification; Radio transmission and reception; Part 3: Range 1 and Range 2 Interworking operation with other radios (3GPP TS 38.521-3 version 16.6.0 Release 16).
They also add the following standard:
ETSI TS 138 521-2 V16.6.0 (2021-02) - 5G; NR; User Equipment (UE) conformance specification; Radio transmission and reception; Part 2: Range 2 standalone (3GPP TS 38.521-2 version 16.6.0 Release 16).
