B.3 High speed train condition
36.1413GPPBase Station (BS) conformance testingEvolved Universal Terrestrial Radio Access (EUTRA)Release 17TS
High speed train conditions are as follows:
Scenario 1 / Scenario 1LTE500a / Scenario 1LTE500b: Open space
Scenario 3 / Scenario 3LTE500a / Scenario 3LTE500b: Tunnel for multiantennas
The high speed train conditions for the test of the baseband performance are two nonfading propagation channels in both scenarios. For BS with Rx diversity defined in scenario 1 / Scenario 1LTE500a / Scenario 1LTE500b, the Doppler shift variation is the same between antennas.
Doppler shift for both scenarios is given by:
(B.3.1)
where is the Doppler shift and is the maximum Doppler frequency. The cosine of angle is given by:
, (B.3.2)
, (B.3.3)
, (B.3.4)
where is the initial distance of the train from BS, and is BSRailway track distance, both in meters; is the velocity of the train in m/s, is time in seconds.
Doppler shift and cosine angle is given by equations B.3.1 and B.3.2B.3.4 respectively, where the required input parameters listed in Table B.31 and B.32, and the resulting Doppler shift is shown in Figure B.31, B.32, B.33, B.34, B.35 and B.36 are applied for all frequency bands.
