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.

摘要： A signal transmission method checks, when detecting an occurrence of a communication request, whether the communication request is a high speed communication (step S302). In the case of the high speed communication, it checks whether the number of current high speed communications (m) plus one is greater than the upper limit (mmax) of the high speed communication (step S312). If greater, it cancels the request as a call loss (S316), and sets to a variable a the ratio (h) of the rate of the high speed communication to that of a low speed communication. If the communication request is the low speed communication, it sets one to the variable a (step S304). It compares n plus a with nmax (step S306), where n is the total number of all the current communications, a is the value associated with the communication request, and nmax is the upper limit of the number of communications acceptable in a bandwidth, all of which are expressed in terms of the number of the low speed communications. If n plus a is greater than nmax, the communication request is canceled as a call loss (S316). Otherwise, the total number of the current high speed communications (m) and the total number of all the current communications (n) expressed in terms of the number of the low speed communications are updated, and a channel is assigned to the communication request (step S310).

摘要： A control method of searching for a neighboring cell of a mobile station communicating with a base-station is provided in a direct sequence CDMA mobile communication system which transmits information by carrying out double modulation using a first spreading code group and a second spreading code. The first spreading code group includes spreading codes that have a same repetition period as an information symbol period and are used in common by the base stations, and the second spreading code has a repetition period longer than the information symbol period. The base stations are assigned different second spreading codes. The control method stores at least one second spreading code and its phase into a first table, which second spreading code corresponds to a perch channel whose second spreading code and phase are known; stores a second spreading code used by a neighboring base station into a second table; searches for a perch channel whose second spreading code and phase are unknown; and searches for a perch channel whose second spreading code and phase are known. The neighboring cell search method can save the power consumption and time required for the mobile station to carry out the cell search with preventing an increase in the total cost of the system.
