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.

Claims

1. Wireless telecommunication method, comprising the steps of:

transmitting data on a first channel at a first frequency in selected time slots within time frames;

receiving data on a second channel of a second frequency in selected time slots within time frames, the first frequency and second frequency being offset; and

transmitting or receiving data on a third channel at a third frequency, different from the first frequency and second frequency, and in time slots in which data is not sent on the first channel nor the second channel.

2. The method of claim 1, wherein the third channel is set on a bearer channel shared between a plurality of user terminals.

3. The method of apparatus according to claim 1, wherein the third channel is a Down Link Shared Channel (DSCH).

4. The method of claim 1 in which the third channel is a Common Packet Channel.

5. A method of wireless telecommunication, comprising the steps of:

transmitting downlink data on a first channel in selected time slots within time frames and at a first frequency;

receiving uplink data on a second channel in selected time slots within time frames and at a second frequency; and

transmitting or receiving further data on a third channel at a third frequency, in timeslots in which data is not sent on the first channel nor the second channel.

6. A method of wireless telecommunication, comprising the steps of:

transmitting uplink data on a first channel in selected time slots within time frames and at a first frequency;

receiving downlink data on a second channel in selected time slots within time frames and at a second frequency; and

transmitting or receiving further data on a third channel at a third frequency, in timeslots in which data is not sent on the first channel nor the second channel.
