Method of predicting the received power level at a base station of a CDMA network and base station implementing the method
First Claim
1. A method of predicting a received power level at a base station receiving signals transmitted by users, called active users, assuming the admission of an additional user, called a candidate user, by said base station, as a function of a power level actually received by said base station, said method consisting in, assuming admission of said candidate user by said base station, taking into account an increase in the individual power levels of said active users;
- wherein the relationship between said power level {tilde over (P)}rxtot received by said base station assuming admission of said candidate user by said base station and said power level Prxtot actually received by said base station from said active users is of the form;

Abstract
The invention concerns in particular a method of predicting a power level received by a base station assuming admission of a candidate user by the base station. According to the invention, the method consists in allowing for the impact of introducing the candidate user on the status of the system, this impact being reflected in an increase in the individual power levels of all users served by the base station.

8. A method, comprising:
-
transmitting a first signal from a first mobile station and a second signal from a second mobile station to a base station of a mobile radio system, wherein the first and second mobile stations are admitted to the mobile radio system;
determining a first total power level, the first total power level comprising a first individual power level, with which the first signal of the first mobile station is received by the base station, and a second individual power level, with which the second signal of the second mobile station is received by the base station;
receiving an admission request signal from a third mobile station, which is seeking admission to the mobile radio system; and
predicting a second total power level, with which signals of the first, second and third mobile stations would be received at the base station, if the third mobile station were to be admitted to the mobile radio system, taking into account an increase of the first and second individual power levels of the first and second mobile stations, respectively.
