Study of TD-LTE Coverage and Uplink/Downlink Power Budget in High-Speed Train

Abstract:

The signal coverage technology and the difficulties of TD-LTE coverage in High-speed Train are summarized. The method of the TD-LTE uplink/downlink power budget is mentioned and the path loss and power budget are calculated in ordinary scene and tunnel scene respectively. The results show that in the F working frequency band of the TD-LTE, the maximum path loss of the High-speed Train is allowable to reach 110~130 dB. In the ordinary scene, by using large power station and a high gain antenna, the outdoor coverage radius of TD-LTE is up to 600~1000m. In the tunnel scene, using the leaked cable, the coverage radius of the RRU is up to 500m.
