In this contribution, a measurement campaign for high- speed-train (HST) channel is introduced where the down- link signals of in-service Long Time Evolution-Advanced (LTE-A) network deployed along the HST railway between Beijing to Shanghai are acquired. Channel impulse responses (CIRs) are extracted from received signals, and concatenated power delay profiles (CPDPs) are illustrated. According to the delay trajectories of the CPDPs, measurement scenarios are categorized into non- tunnel and tunnel scenarios. The delay spread and K- factor are investigated for both scenarios. The results show that the two scenarios have distinguishable statistics in delay spread and K-factor.
