METHOD FOR MULTIPLEXING UE SIGNALS HAVING DIFFERENT BANDWIDTH, AND METHOD FOR TRANSMITTING UPLINK SIGNAL

摘要

A method for multiplexing UE signals having various bandwidths and a method for transmitting an uplink signal are provided to maintain orthogonality even when lengths are difference between sequences for multiplexing, thereby maintaining a CDM(Code Division Multiplexing) mode as a multiplexing mode and enabling a base station to discriminate from which UE a received uplink signal is transmitted. A multiplexing method comprises the following steps of: setting a bandwidth, corresponding to a common measure of bandwidths used by each of plural UEs(User Equipments), as a reference bandwidth; selecting reference sequences corresponding to the reference bandwidth in order to multiplex signals of the plural UEs; and multiplexing the signal by using a sequence made by repeating the reference sequence if the signal is a signal of a UE using a bandwidth more than the reference bandwidth among the plural UEs.
