摘要： A method and an apparatus for signal transmission in a CDMA mobile communication system which are capable of preventing an unnecessary increase of an amount of interference power due to the signal transmission through a radio channel and thereby preventing an unnecessary decrease of a system capacity. The radio channel transmission signals are transmitted through the radio channel, where the radio channel transmission signals contain the transmission signals which are formed by control signals or user signals and necessary signals which are necessary in maintaining the radio channel, and this radio channel transmission is controlled so that only signal portions for the necessary portions are transmitted without transmitting any other signal portions when there is no transmission signal to be transmitted.

摘要： A mobile station position estimation scheme for a cellular mobile communication system which is capable of estimating a position of a mobile station in a simple manner even in the general cellular mobile communication systems in which base stations are not synchronized. According to this mobile station position estimation scheme, a first signal sequence and a second signal sequence which are uniquely predetermined for the mobile station are exchanged between the mobile station and the base station, and then a position of the mobile station is estimated at one station among the base station and the mobile station, by obtaining a phase difference between the first signal sequence and the second signal sequence and calculating an estimated distance between the base station and the mobile station according to the phase difference.

摘要： A cell selection scheme in a CDMA mobile communication system which is capable of shortening the cell selection processing time while constructing a mobile communication system with a practically feasible base station configuration. In a CDMA mobile communication system, first type base stations which share a common reference timing are transmitting pilot channels spread by using an identical pilot channel spread code at mutually different spread code phases with respect to the common reference timing where these mutually different spread code phases are assigned to different first type base stations, and second type base stations which do not share the common reference timing are transmitting pilot channels spread by using mutually different pilot channel spread codes at arbitrary spread code phases where these mutually different pilot channel spread codes being assigned to different second type base stations. A mobile station receives these pilot channels and judges a located cell of the mobile station according to receiving levels, pilot channel spread codes and spread code phases of received pilot channels.
