US 2002/0164986 A1 · Wireless telecommunications apparatus in particular of UMTS or other third generation type and a method of wireless telecommunication

Abstract

Wireless telecommunications apparatus and method. A base station sends data to a user terminal on a first channel at a first frequency in selected time slots and the user terminal sends data to the base station at a second frequency in selected time slots. These two frequencies are different. The network also either includes a transmitter which transmits further data to the user equipment at a third frequency in time slots in which the other data is not being sent or includes a receiver which receives further data from the user equipment at the third frequency in time slots in which the other data is not being sent. The apparatus can be a UMTS or other third generation system.
