Abstract: A controlling radio network controller (C-RNC) for use in radio resource management (RRM) functions includes a radio resource management function for managing radio resources. The RRM function uses data stored in a common database, including cell data and wireless transmit/receive unit (WTRU) data. The cell data includes resource assignment information for a cell, and the WTRU data includes WTRU capability and WTRU radio link information.

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.

Abstract: A method of fast dynamic channel allocation call admission control for radio link addition includes a pre-code allocation process, a signal-independent code allocation process, and a post-code allocation process. The pre-code allocation process receives and processes a request message, retrieves the new cell identification from the message, and retrieves the old cell identification and system information from a centralized database. The code allocation process checks the availability of a code set in the new cell, generates timeslot sequences for the available timeslots, and assigns a code set 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 process stores the new radio link information in the database and creates a response message with new allocation information.

Abstract: A method of implementing a fast dynamic channel allocation background interference reduction procedure in a wireless communication system includes a pre-code allocation process, a signal-independent code allocation process, and a post-code allocation process. The pre-code allocation process receives a timer trigger signal and retrieves system measurements from a centralized database. The physical resources to be reassigned are determined based on a figure of merit. The code allocation process checks the availability of a code set in the cell and generates timeslot sequences for the available timeslots. A code set is allocated 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 reallocation information is stored in the centralized database and is sent in a physical channel reconfiguration request message.

Abstract: A method of implementing fast dynamic channel allocation call admission control for radio link reconfiguration 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 request message and retrieves system measurements and wireless transmit/receive unit (WTRU) capability information from a centralized database. A list of available timeslots and a list of code sets is retrieved from the centralized database. The code sets are allocated to the available timeslots, wherein a successful assignment is a solution. The solution having the lowest weighted interference signal code power is an optimal solution. The WTRU information with new allocation information is updated in the centralized database. A radio link reconfiguration ready message with the results of the code allocation process is then sent.
