A.4 Measurement Performance Requirements

37.1713GPPRelease 16TSUniversal Terrestrial Radio Access (UTRA) and Evolved UTRA (E-UTRA)User Equipment (UE) performance requirements for RAT-Independent positioning enhancements

A.4.1 General

Unless explicitly stated otherwise:

РReported measurements shall be within defined range of accuracy limits defined in clause 5 for at least 90 % of the reported cases. If multiple measurement performance requirements are verified in the same test, the reported measurements for each requirement shall be within defined range of accuracy limits of the corresponding requirement defined in clause 5 for at least 90% of the reported cases.

– Measurements are performed in RRC_CONNECTED state.

A.4.2 MBS Code Phase Measurement Accuracy Requirements in AWGN

A.4.2.1 Test Purpose and Environment

The purpose of this test is to verify that the MBS Code Phase measurement accuracy is within the specified limits. This single test will verify the requirements in clauses 5.2, 5.3 and 5.4 for MBS measurements. The channel type for this test is AWGN, as specified in the appropriate sub-clause of clause 5. This test can be used for NR, UTRA and E-UTRA testing.

In each test, there is one beacon transmitted in each of four consecutive beacon slots. The position of first of the four consecutive beacons in the beacon transmission period can be any slot, but it is static for the duration of the test. In other slots there are no simulated beacons. All beacons are in the same time slotted RF channel, with centre frequency of 925.977 MHz or set using the network assistance data. All beacons are of type TB1 (2 MHz) [7], or set using the network assistance data in Release 14, and the data transmitted is in Type 2 packets with the following data fields: The MBS Transmitter ID and the Slot Index shall be set to the MBS slot number; All other beacon payload data shall be populated with zeros.

In the four slots containing beacon transmissions, every other slot shall contain a beacon with the higher signal strength beacon, and the other slots shall contain a beacon with the lower signal strength.

The higher power beacons (-30 dBm) shall have code phase delay of 1.6678×10-4 ms (corresponding to 50 m) and the lower power beacons (-130 dBm) shall have code phase delay of 5.00346×10-3 ms (corresponding to 1500 m).

Each of the beacons shall use a unique PN code chosen from the PN code list for TB1 [7].

If the UE supports MBS assistance data, the UE will receive the MBS assistance data for each beacon via LPP, according to Annex A.

A.4.2.2 Test Requirements

The MBS Code Phase measurement accuracy shall fulfil the requirements in clauses 5.2, 5.3 and 5.4.

A.4.3 MBS Code Phase Measurement Accuracy Requirements in Multipath

A.4.3.1 Test Purpose and Environment

The purpose of this test is to verify that the MBS Code Phase measurement accuracy is within the specified limits. This test will verify the requirements in clause 5.5 for MBS measurements. The channel type for the test is specified in clause 5.5. This test can be used for NR, UTRA and E-UTRA testing.

In this test, there is one beacon transmitted in each of two chosen slots. The position of the beacons in the beacon transmission period is static for the duration of the test. In other slots there are no simulated beacons. Both beacons are in the same time slotted RF channel, with centre frequency of 925.977 MHz or set using the network assistance data. All beacons are of type TB1 (2 MHz) [7], or set using the network assistance data in Release 14, and the data transmitted is in Type 2 packets with the following data fields: The MBS Transmitter ID and the Slot Index shall be set to the MBS slot number; All other beacon payload data shall be populated with zeros.

Both beacon slots shall contain a beacon with the signal strength listed in clause 5.5.

The beacons shall have code phase delay of 1.6678×10-4 ms (corresponding to 50 m).

Each of the beacons shall use a unique PN code chosen from the PN code list for TB1 [7].

If the UE supports MBS assistance data, the UE will receive the MBS assistance data for each beacon via LPP, according to Annex A.
