Annex Q (informative): RTS Anechoic Chamber Specification and Validation Method
Q.1 RTS anechoic chamber specifications
The RTS Anechoic Chamber implementation is based on the full SCME implementation described in TR 37.977 [29] clause 6.3.1.3 and would be evaluated for shielding effectiveness in accordance with Annex G.1 and would follow the recommendations in Annex A.3.5.
Q.2 RTS anechoic chamber minimum distance between the DUT and the measurement antenna
The RTS anechoic chamber minimum distance between the DUT and the measurement antenna would follow the recommendations in Annex A.3.3.
Q.3 RTS anechoic chamber quiet zone reflectivity level validation
The RTS anechoic chamber quiet zone relectivity level validation is performed in accordance with Annex G.2 and Annex G.3 and would follow the recommendations in Annex A.3.2 and Annex A.3.4.
Q.4 RTS anechoic chamber channel model verification
The RTS anechoic chamber channel model verification is performed in accordance with TR 37.977 [29] clause 8.3 for the channel model defined in clause 7.4.1.2 at the downlink centre frequency of the mid-channel defined in TS 36.508 [10] for the operating bands defined in clause 7.4.1.2. The results are expected to meet the recommended limits in TR 37.977 [29] clause 8.3.3.
Annex R: UE ATF Requirements
This annex defines the accuracy requirements for the RSAP and RSARP measurements, these requirements are normative for devices using the RTS method as defined in section 7.4.
It should be noted that the two-stage test method includes RSAP and RSARP validation and if necessary linearization of the results prior to calibration of the results against known radiated metrology standards, therefore the requirement for RSAP and RSARP is that they are monotonic over a given range and resolution. As a consequence their absolute accuracies are not relevant. However, due to the similarity with RSRP, in order to guide RSAP implementation, an upper bound limit on accuracy is defined for RSAP. Since RSAP is measured in much easier conditions than RSRP, the RSRP absolute requirement will not increase the demands on existing receiver designs.
R.1 RSAP
The requirements for RSAP accuracy are given in Table R-1.
Table R-1: Reference Signal Antenna Power requirements
Parameter |
Value |
Absolute accuracy |
± 6 dB |
Range |
RSAP absolute accuracy and monotonicity to be maintained over the range -60 dBm to -80 dBm incident power measured at the orientation of the DUT’s maximum antenna gain. |
Monotonicity |
Monotonicity over a 1 dB interval. This is necessary to enable linearization of the UE RSAP response as part of the accuracy requirements for the derived complex antenna pattern. |
R.2 RSARP
The requirements for RSARP accuracy are given in Table R-2.
Table R-2: Reference Signal Antenna Relative Phase requirements
Parameter |
Value |
Range |
RSARP monotonicity to be maintained over the range -60 dBm to -80 dBm incident power measured at the orientation of the DUT’s maximum antenna gain. |
Monotonicity |
Monotonicity over a 5 degree interval. This is necessary to enable linearization of the UE RSARP response as part of the accuracy requirements for the derived complex antenna pattern. |
