Wireless telecommunications system and method for asymmetric data transmission

摘要

Wireless telecommunications apparatus comprises a base station and a user terminal. The base station sends data to the user terminal on a first channel (DL1) at a first frequency (f1) in selected time slots and the user terminal sends data to the base station on a second channel (UL2) at a second frequency (f2) in selected time slots. These two frequencies are different. The network also either includes a transmitter which transmits further data to the user equipment on a shared channel (DL0) at a third frequency (f0) in time slots in which the other data is not being sent or includes a receiver which receives further data from the user equipment on a shared channel 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. <IMAGE>
