Verfahren zur Semaphorkanalübertragung und Zellauswahl in einem CDMA Übertragungssystem

摘要

A perch channel transmission and cell selection method for a CDMA mobile communication system which is capable increasing a system capacity by reducing an amount of interference power. In this method, each base station intermittently transmits a perch channel which is spread by using a spread code assigned to each base station. Then, a mobile station receives more than one perch channels transmitted from more than one base stations, measures a receiving level of an intermittently transmitted portion of each received perch channel, and judges a located cell according to measured receiving levels of these more than one perch channels.
