Method for implementing fast dynamic channel allocation escape mechanism in radio resource management
First Claim
1. A method of implementing a fast dynamic channel allocation escape procedure in a wireless communication system, comprising:
- a pre-code allocation procedure;
a signal-independent code allocation procedure, including;
checking the availability of a code set in the cell;
checking the transmission power of a candidate timeslot;
checking if the interference signal code power (ISCP) for other timeslots is lower than the ISCP of the candidate timeslot;
generating timeslot sequences for the available timeslots;
assigning a code set to the available timeslots in a timeslot sequence, wherein a successful assignment is a solution;
calculating the ISCP for each solution; and
selecting the solution having the lowest weighted ISCP as an optimal solution; and
a post-code allocation procedure.

Abstract
A method of implementing a fast dynamic channel allocation escape procedure in a wireless communication system includes a pre-code allocation procedure, a signal-independent code allocation procedure, and a post-code allocation procedure. The pre-code allocation procedure receives and processes a measurement trigger signal, retrieves system measurements from a centralized database, and determines physical resources to be reassigned. The code allocation procedure checks the availability of a code set in the cell and generates timeslot sequences for the available timeslots. A code set is assigned to the available timeslots in a timeslot sequence, wherein a successful assignment is a solution. The interference signal code power (ISCP) is calculated for each solution and the solution having the lowest weighted ISCP is selected as an optimal solution. The post-code allocation procedure stores the reallocation information in the centralized database and creates a physical channel reconfiguration request message.
