1. A method for radio resource control (RRC) in the WCDMA system, comprising the following iterative steps:

  • obtaining a system state x and an action A(x) using an incoming request, a mean of interference Im and a variance of interference Iv;

    obtaining Q values based on x and A(x) by using Im, Iv,a change of mean Δ

    Im and a change of variance Δ

    Iv;

    allocating an optimal action A*(x) using the Q values; and

    updating the Q values using a state y and a cost function based on x and A*(x) when a new request with the state y arrives.
