A cell search method and a base station for a code division multiple access mobile communication system

摘要

The present invention relates to a cell search method for a code division multiple access mobile communication system, comprising: transmitting, from a base station, a control signal via perch channels (106, 107), said perch channels being formed such that a long period code assigned to said base station and a first short period code are mapped in a first section (102) of one slot of said perch channel; and transmitting, from said base station, a predetermined short period code mapped in a second section (131) of said one slot. Said predetermined short period code is provided for use by a mobile terminal for performing cell search by calculating a correlation value for said second section of said one slot. Said predetermined short period code is transmitted plural times within said second section of said one slot.
