For LTE, the WLAN measurement time is defined as the time starting from the moment that the UE has received the LPP message of type REQUEST LOCATION INFORMATION, and ending when the UE starts sending the LPP message of type PROVIDE LOCATION INFORMATION on the Uu interface. The response times specified for all test cases are based on new measurements unless otherwise stated, i.e. the UE shall not re use any information on measurements or other aiding data that was previously acquired or calculated and stored internally in the UE. A dedicated test message ‘RESET UE POSITIONING STORED INFORMATION’ has been defined in TS 36.509 [11] clause 6.9 for the purpose of deleting this information. No WLAN assistance data is provided to the UE.

The signals from the WLAN APs shall be available at the UE for the duration of the measurement time. Each WLAN AP transmits a beacon signal with a beacon interval smaller or equal to 102.4 ms. The beacon frames from different access points shall be transmitted in different time slots or non-overlapping frequency channels. The beacon frames have variable time duration of ~1ms.

The WLAN Measurement Reporting Delay is given as:

sec

where:

is the total time for detecting and measuring the WLAN Access Points

is the elapsed time from the trigger of the measurement to the start of the first WLAN transmission period and is shown in Figure 12.1.1.3-1.

Figure 12.1.1.3-1: Illustration of the WLAN Measurement Time

The normative reference for the WLAN reporting delay requirement is 3GPP TS 37.171 [39] clause 4.3 and the normative reference for the WLAN AP Identification under nominal conditions requirement is 3GPP TS 37.171 [39] clause 7.3.

12.2.1.5 Test requirement

The UE shall send BT-ProvideLocationInformation, within a maximum response time of 11.15 seconds (including test tolerance of 300ms) from the beginning of time period T2. The maximum response time is equal to the LPP time IE value of 11 seconds, minus ΔT, where ΔT = 150 ms, plus the test tolerance of 300ms. The LPP time IE value is derived from TBT_meas, where TBT_meas is 10.24 seconds as described in clause 12.2.1.3, plus one broadcast interval, which is taken as 100 ms, giving a total value of 10.34 seconds which is then rounded up to the next allowed LPP value of 11 seconds.

The BT‑ProvideLocationInformation IE shall include BT Measurements for all of the simulated BLE devices identified by the corresponding UUID.

The rate of correct events observed during repeated tests shall be at least 90% with a confidence level of 95%.

Propagation Condition

AWGN

Antenna Configuration

1×2

Note 1: OCNG shall be used such that all cells are fully allocated and a constant total transmitted power spectral density is achieved for all OFDM symbols.

Note 2: Interference from other cells and noise sources not specified in the test is assumed to be constant over subcarriers and time and shall be modelled as AWGN of appropriate power for Noc1 to be fulfilled.

Note 3: Interference from other cells and noise sources not specified in the test is assumed to be constant over the bandwidth and time and shall be modelled as AWGN of appropriate power for Noc2 to be fulfilled.

Note 4: Es/Iot, RSRP, SCH_RP, Io and Bluetooth RSSI have been derived from other parameters for information purposes. They are not settable parameters themselves.

Note 5 The resources for uplink transmission are assigned to the UE prior to the start of time period T2.

Note 6: If Cell 1 is LTE FDD, the FDD OCNG and RMCs shall be used. If Cell 1 is LTE TDD, the TDD OCNG and RMCs shall be used
