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 transmitting information by a device in a network in a mobile communication system, the method comprising:

transmitting, by the device, control information via a shared control channel via a first portion of a subframe to at least one user equipment, the control information comprising indication information and scheduling information,

wherein the indication information indicates

that the shared control channel corresponds to a specific logical channel, the specific logical channel being a Broadcast Control Channel (BCCH) or a Paging Control Channel (PCCH), and

that a control message will be transmitted via a shared data channel, the control message being a broadcast control message or a paging control message respectively corresponding to the BCCH and the PCCH, and

wherein the scheduling information indicates where a resource block (RB) containing the control message is located within a time domain and a frequency domain of the shared data channel; and

transmitting, by the device to the at least one user equipment via the shared data channel via a remaining portion of the subframe, the control message based on the indication information and the scheduling information,

wherein the first portion of the subframe and the remaining portion of the subframe are contiguous portions, and

wherein the indication information comprises a logical channel identifier.

2. The method of claim 1, wherein the indication information is transmitted periodically during a first period.

3. The method of claim 2, wherein the scheduling information is transmitted periodically during a second period after transmitting the indication information.

13. The method of claim 1, wherein the control message is a paging information message or a system information message.

4. A method of receiving information by a user equipment (UE) in a mobile communication system, the method comprising:

receiving, by the UE, control information via a shared control channel via a first portion of a subframe, the control information comprising indication information and scheduling information,

wherein the indication information indicates

that the shared control channel corresponds to a specific logical channel, the specific logical channel being a Broadcast Control Channel (BCCH) or a Paging Control Channel (PCCH), and

that a control message will be transmitted via a shared data channel, the control message being a broadcast control message or a paging control message respectively corresponding to the BCCH and the PCCH, and

wherein the scheduling information indicates where a resource block (RB) containing the control message is located within a time domain and a frequency domain of the shared data channel; and

receiving, by the UE via the shared data channel via a remaining portion of the subframe, the control message based on the indication information and the scheduling information,

wherein the first portion of the subframe and the remaining portion of the subframe are contiguous portions, and

wherein the indication information comprises a logical channel identifier.

5. The method of claim 4, wherein the indication information is received periodically during a first period.

6. The method of claim 5, wherein the scheduling information is received periodically during a second period after receiving the indication information.

14. The method of claim 4, wherein the control message is a paging information message or a system information message.

7. A base station configured to operate in a wireless network, the base station comprising:

a transmitter configured to;

transmit control information to at least one user equipment via a shared control channel via a first portion of a subframe, the control information comprising indication information and scheduling information,

wherein the indication information indicates

that the shared control channel corresponds to a specific logical channel, the specific logical channel being a Broadcast Control Channel (BCCH) or a Paging Control Channel (PCCH), and

that a control message will be transmitted via a shared data channel, the control message being a broadcast control message or a paging control message respectively corresponding to the BCCH and the PCCH, and

wherein the scheduling information indicates where a resource block (RB) containing the control message is located within a time domain and a frequency domain of the shared data channel; and

transmit, to the at least one user equipment via the shared data channel via a remaining portion of the subframe, the control message based on the indication information and the scheduling information,

wherein the first portion of the subframe and the remaining portion of the subframe are contiguous portions, and

wherein the first indication information comprises a logical identifier.

8. The base station of claim 7, wherein the transmitter is further configured to transmit the indication information periodically during a first period.

9. The base station of claim 8, wherein the transmitter is further configured to transmit the scheduling information periodically during a second period after transmitting the indication information.

15. The base station of claim 7, wherein the control message is a paging information message or a system information message.

10. A user equipment configured to operate in a wireless network, the user equipment comprising:

a receiver configured to;

receive control information from a base station via a shared control channel via a first portion of a subframe, the control information comprising indication information and scheduling information,

wherein the indication information indicates

that the shared control channel corresponds to a specific logical channel, the specific logical channel a Broadcast Control Channel (BCCH) or a Paging Control Channel (PCCH), and

that a control message will be transmitted via a shared data channel, the control message being a broadcast control message or a paging control message respectively corresponding to the BCCH and the PCCH, and

wherein the scheduling information indicates where a resource block (RB) containing the control message is located within a time domain and a frequency domain of the shared data channel; and

receive, from the base station via the shared data channel via a remaining portion of the subframe, the control message based on the indication information and the scheduling information,

wherein the first portion of the subframe and the remaining portion of the subframe are continuous portions, and

wherein the indication information comprises a logical channel identifier.

11. The user equipment of claim 10, wherein the receiver is further configured to receive the indication information periodically during a first period.

12. The user equipment of claim 11, wherein the receiver is further configured to receive the scheduling information periodically during a second period after receiving the indication information.

16. The user equipment of claim 10, wherein the control message is a paging information message or a system information message.
