Title:
WIRELESS COMMUNICATION METHOD AND TERMINAL FOR RAIL TRANSIT
Document Type and Number:
WIPO Patent Application WO/2018/094771
Kind Code:
A1
Abstract:
The present invention provides a wireless communication method for rail transit. The method comprises: performing signaling interaction with a source cell base station after entering a source cell and obtaining a handover threshold parameter, the handover threshold parameter comprising distance information between a handover point and the source cell base station and signal intensity information; determining the handoff point based on the handover threshold parameter; and performing channel measurement when the handover point is reached and performing a handover from the source cell to a destination cell. The present invention also provides a terminal for use in rail transit. A handover point is accurately determined according the signal intensities of different terminal users in different directions, allowing the terminal users to complete a cell handover in only a single measurement process in most cases, which greatly reduces the number of measurements, reduces the costs of cell handovers, and improves the communication efficiency of the overall system.
