Abstract

A method and apparatus for providing new configurations for transmitting control information between a mobile terminal and a network using a common control channel (CCCH) logical channel/transport channel. The new configurations enable messages to be sent that are larger than currently allowed and the availability of the new configurations is indicated such that mobile terminals that do not support the new configurations are not impacted.

Claims

1. A method of transmitting a data in wireless communication system, the method comprising:

receiving a first message from a network, wherein the first message comprises at least one available configuration that is physical random access channel (PRACH) information related to a common control channel (CCCH) and the PRACH information relates to additional transport format information for the CCCH; and

transmitting, by a processing unit, a second message over the CCCH using the additional transport format information based on a selected configuration from the at least one available configuration,

wherein the additional transport format Information comprises an RLC (Radio Link Control) size, a transport block size, or a number of transport blocks.

2. The method of claim 1, wherein the first message is a radio resource control (RRC) message.

3. The method of claim 2, wherein the RRC message is related to a signaling radio bearer 0 (SRB0).

4. The method of claim 1, wherein the at least one available configuration comprises a legacy configuration mode and legacy configuration identity.

5. The method of claim 1, wherein the at least one available configuration comprises a predefined configuration mode and a predefined configuration identity.

6. The method of claim 5, wherein the predefined configuration mode comprises at least an additional channel, an increased message block size for an existing channel, a new channel mapping configuration, or a new message format.

7. The method of claim 6, wherein the additional channel comprises at least a logical channel or a physical channel.

8. The method of claim 6, wherein the existing channel comprises at least a logical channel or a physical channel.

9. The method of claim 6, wherein the new channel mapping configuration is associated with mapping a logical channel to a physical channel.

10. A method of transmitting a data in wireless communication system, the method comprising:

receiving a message from a network, wherein the message comprises at least one available configuration that is physical random access channel (PRACH) information related to a common control channel (CCCH) and the PRACH information relates to additional random access channel (RACH) transport format information for the CCCH; and

transmitting, by a processing unit, data using the additional RACH transport format information based on a selected configuration from the at least one available configuration,

wherein the additional RACH transport format information comprises power offset information.

11. The method of claim 10, wherein the message is a radio resource control (RRC) message.

12. The method of claim 11, wherein the RRC message is related to a signaling radio bearer 0 (SRB0).

13. The method of claim 10, wherein the at least one available configuration comprises a legacy configuration mode and legacy configuration identity.

14. The method of claim 10, wherein the at least one available configuration comprises a predefined configuration mode and a predefined configuration identity.

15. The method of claim 14, wherein the predefined configuration mode comprises at least an additional channel, an increased message block size for an existing channel, a new channel mapping configuration, or a new message format.

16. The method of claim 15, wherein the additional channel comprises at least a logical channel or a physical channel.

17. The method of claim 15, wherein the existing channel comprises at least a logical channel or a physical channel.

18. The method of claim 15, wherein the new channel mapping configuration is associated with mapping a logical channel to a physical channel.
