Abstract

A method for physical layer random access in wideband TDD mobile communication system is disclosed, and the method comprises: receiving the system broadcast message of the cell, obtaining the configuration information of the frequency band in frequency domain in the UpPTS time slot of the cell; and the terminal sends random access sequences to the BS in the UpPTS time slot according to the configuration information of the frequency band in the UpPTS time slot. The configuration information of the frequency band in frequency domain in the UpPTS time slot comprises the information about the frequency band number that the total bandwidth used is divided in the UpPTS time slot, the information about the bandwidth size of each frequency band, and the information about the position of the frequency point. Phod, device and terminal for physical layer random access in wideband TDD mobile communication system provided in the present invention can use the frequency bands whose time slots are different to perform network access, which can reduce the competition and collision probability when sending random access sequences, and can realize an efficient random access procedure.
