1. A method for reusing timeslots designated for transmission of control information for user traffic, the method comprising the steps of:
- identifying timeslots designated for transmission of control information within a wireless communication system including a plurality of cells;
allocating the timeslots designated for transmission of control information throughout the plurality of cells so that a time slot allocated for transmission of control information in a first cell is not used for transmission of control information in any cells neighboring said first cell; and
wherein said time slot allocated for transmission of control information in the first cell is reused for user traffic in cells neighboring the first cell.

Abstract
A method and system is disclosed wherein timeslots designated in a wireless communication system as Common Physical Channel (CPCH) timeslots may be reused for user traffic. A CPCH timeslot used in a first cell may be reused by a second cell, assuming the first and second cells transmit control information in different CPCH timeslots, for user traffic. The second cell is permitted to reuse the timeslot in which the first cell is transmitting control information so long as the second cell'"'"'s reuse of that timeslot does not degrade reception of control information in the first cell.

8. A method for reusing Common Physical Channel (CPCH) timeslots for user traffic within a first cell of a wireless communication system, the system including a plurality of cells and each cell transmitting control information in an allocated CPCH timeslot, the method comprising:
transmitting and receiving user traffic in CPCH timeslots which are utilized for transmission of control information in cells neighboring said first cell.

9. A wireless communication system wherein timeslots designated for transmission of control information may be reused for user traffic, the system comprising:
-
a plurality of wireless transmit/receive units (WTRUs) configured to report performance measurements regarding the quality with which they receive control information; at least one base station configured to receive the performance measurements provided by the WTRUs and obtain the location of each WTRU reporting the performance measurements; and a radio network controller (RNC) configured to identify base stations whose reuse of timeslots designated for transmission of control information is degrading reception of control information at another base station and adjust the power with which said base stations are reusing said timeslots. - View Dependent Claims (10, 11, 12)
