Abstract: PROBLEM TO BE SOLVED: To provide a frame structure for cellular telecommunication systems. SOLUTION: In order to double the size of cells for a UMTS/ UTRAN(Universal Mobile Terrestrial System/UMTS Terrestrial Radio Access Network) system operating in time division mode (TDD) from 3.75 km to 7.5 km, the node B station defines a guard period (66) for a downlink slot followed by an adjacent uplink slot to be longer than the guard period (68) for an uplink slot, followed by an adjacent downlink slot, whereby the cell size is extended. Each UE(user equipment) adjusts its timing, in response to timing deviation signals (64) transmitted at the start of each downlink burst, so as to transmit an uplink burst which arrive at the node B, at the beginning of the next uplink slot.

Abstract: 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.
