Abstract:
1. A method for physical layer random access in a wideband time division duplex mobile communication system in which there is an UpPTS uplink access timeslot for random access, wherein the method comprises: a) receiving a system broadcast message of a cell, and obtaining frequency band configuration information on the UpPTS timeslot of the cell in the frequency domain; b) transmitting a random access sequence to a base station in the UpPTS timeslot in accordance with the frequency band configuration information on the UpPTS timeslot in the frequency domain; and c) retransmitting the random access sequence if no response message from the base station is received within a predetermined period; and proceeding with a subsequent processing flow for the random access if a response message is received within the predetermined period, wherein the frequency band configuration information on the UpPTS timeslot in the frequency domain comprises information on the number of frequency bands into which the UpPTS timeslot is divided over the entire used bandwidth, information in bandwidths of the respective frequency bands, and information on frequency point locations of the respective frequency bands.
