Abstract

A method of receiving control information by a terminal in a mobile communications system having a single control channel and a plurality of common channels and having a network that periodically transmits the control information via the control channel, the method comprising: periodically receiving the control channel; detecting, at a particular time, an identifier from the received control channel; and receiving data via a particular common channel that is indicated by control information that includes the detected identifier.

Claims

1. A method of receiving control information by a terminal in a mobile communications system having a single control channel and a plurality of common channels and having a network that periodically transmits the control information via the control channel, the method comprising:

periodically receiving the control channel;

detecting, at a particular time, an identifier from the received control channel; and

receiving data via a particular common channel that is indicated by control information that includes the detected identifier.

2. The method of claim 1, wherein the identifier is a terminal identifier for the terminal itself or is a common channel identifier.

3. The method of claim 1, wherein at least one of the common channels is a CCCH, a BCCH, a MCCH, a MTCH or a PCCH.

4. The method of claim 1, wherein the control information is received via the control channel.

5. The method of claim 1, wherein the control information and data are received in the same sub-frame.

6. The method of claim 1, wherein the control information and data are received in different sub-frames.

7. The method of claim 1, wherein the control information indicates time and frequency information for the data in the same sub-frame or a different subsequent sub-frame.

8. The method of claim 1, wherein the control information comprises at least one of SCCH, FCCH, and L1/L2 control information.

9. The method of claim 1, wherein the control information indicates at least one of a frequency parameter, a time parameter, and a size parameter of the data to be read.

10. The method of claim 9, wherein the frequency parameter relates to symbols, the time parameter relates to sub-carriers, and the size parameter relates to symbols and sub-carriers.

11. A method of transmitting control information by a network to a terminal in a mobile communications system having a single control channel and a plurality of common channels, the method comprising:

periodically transmitting the control channel; and

transmitting data via a particular common channel that is indicated by control information that includes an identifier detected, at a particular time, by the terminal from the control channel.

12. The method of claim 11, wherein the identifier is a terminal identifier for the terminal itself or is a common channel identifier.

13. The method of claim 11, wherein at least one of the common channels is a CCCH, a BCCH, a MCCH, a MTCH or a PCCH.

14. The method of claim 11, wherein the control information is transmitted via the control channel.

15. The method of claim 11, wherein the control information and data are transmitted in the same sub-frame.

16. The method of claim 11, wherein the control information and data are transmitted in different sub-frames.

17. The method of claim 11, wherein the control information indicates time and frequency information for the data in the same sub-frame or a different subsequent sub-frame.

18. The method of claim 11, wherein the control information comprises at least one of SCCH, FCCH, and L1/L2 control information.

19. The method of claim 11, wherein the control information indicates at least one of a frequency parameter, a time parameter, and a size parameter of the data to be read.

20. The method of claim 19, wherein the frequency parameter relates to symbols, the time parameter relates to sub-carriers, and the size parameter relates to symbols and sub-carriers.
