Abstract:
1. A method for reducing interference between users in a mobile communications network in which uplink transmissions from user equipment to a radio base station can be performed on at least two different carriers, the user equipment supporting dynamic switching between code division multiplexing and time division multiplexing transmission modes and the radio base station being arranged to dynamically set the transmission mode for said user equipment, the method comprising; identifying at least a first user equipment as a high data rate user equipment currently requiring high data transmission rate; dedicating at least one of said at least two carriers to said high data rate user equipment for at least a first period of time, said at least one carrier referred to herein as a clean carrier, and allocating said high data rate user equipment to said clean carrier during said at least first period of time, while ensuring that no user equipment operating in code division multiplexing mode is transmitting on the same carrier as said high data rate user equipment during said period of time.
