The invention provides a method for rail transit wireless data transmission based on LTE. The method solves cofrequency interference problem of LTE data transmission networks under limited frequency range resources conditions. Frequency range switching or ICIC is triggered by combination of speed and distance determined by a base station, and UE on a train carries out inter-frequency handover to a same frequency range for frequency multiplex. In this way, frequencies of other adjacent trains can be made different, and interference can be completely eliminated. When no sufficient frequency ranges can be supplied to two trains to use different frequency ranges and interference has to be eliminated, an on-board train terminal can solve the problem of interference between two trains in a station through a novel method of dynamic frequency switching. The impact on train transmission performance and capacity is minimal.
