37.1053GPPActive Antenna System (AAS) Base Station (BS) transmission and receptionRelease 17TS

9.3.1 General

The OTA AAS BS base station output power is declared as TRP.

9.3.2 OTA Maximum output power

9.3.2.1 General

The rated carrier output power of the OTA AAS BS shall be as specified for UTRA in table 9.3.2.1-1, and for E-UTRA and NR in table 9.3.2.1-2

Table 9.3.2.1-1: UTRA OTA AAS Base Station rated output power limits for BS classes

OTA AAS BS class

PRated,c,TRP

Wide Area BS

(NOTE)

Medium Range BS

≤ 44 dBm

Local Area BS

≤ 30 dBm

NOTE: There is no upper limit for the PRated,c,TRP of the Wide Area Base Station.

9.3.2.2 Minimum requirement for MSR operation

9.3.2.2.1 General

In normal conditions, Pmax,c,TRP shall remain within +2,0 dB and -2,0 dB of the configured carrier TRP as declared by the manufacturer.

In certain regions, the minimum requirement for normal conditions may apply also for some conditions outside the range of conditions defined as normal.

9.3.2.2.2 Additional requirements (regional)

9.3.2.3 Minimum requirement for single RAT UTRA operation

The minimum requirement for single RAT UTRA BS is the same as that defined in subclause 9.3.2.2.

9.3.2.4 Minimum requirement for single RAT E-UTRA operation

9.3.2.4.1 General

The minimum requirement for single RAT E-UTRA BS is the same as that defined in subclause 9.3.2.2.

9.3.2.4.2 Additional requirements (regional)

9.3.3 OTA E-UTRA DL RS power

9.3.3.1 General

This requirement applies to the RIB(s) transmitting primary DL RS.

The DL RS power is the resource element power of the Downlink Reference Symbol at the RIB transmitting the DL RS for a cell.

The absolute DL RS power is indicated on the DL-SCH. The absolute accuracy is defined as the maximum deviation between the DL RS power indicated on the DL-SCH and the DL RS power of each E-UTRA carrier.

9.3.3.2 Minimum requirement for MSR operation

There is no DL RS power requirement for UTRA operation.

There is no DL RS power requirement for NR operation.

The minimum requirement for MSR E-UTRA operation is the same as that defined in subclause 9.3.6.4.

9.3.3.3 Minimum requirement for single RAT UTRA operation

There is no DL RS power requirement for UTRA operation.

9.3.3.4 Minimum requirement for single RAT E-UTRA operation

The DL RS power of each E-UTRA carrier shall be within ±2,1 dB of the DL RS power indicated on the DL-SCH.
