Method for allocating code to cells and planning cell in OFDM cellular system

摘要

the invention of an OFDM based system in the cell -to- cell or inter-base station frame timing , and cell -to- set or base station relates to an inter-code allocation method , a forward included in the frame by using the phase and the external clock to the respective base stations existing on the wireless communication system using the same external clock to create a frame according to the frame timing of a certain unit link comprises the step of transmitting by assigning different offsets to the frames of the neighboring base stations so that each of the common channels are not overlapped with each other , the cell code assignment method for OFDM cellular system, the forward link frame transmission method , how to set timing between cells , can be drawn between the base station and the mobile station timing setting method .
