Abstract

A method for configuring configuration information with a user equipment in a mobile communication system is provided. The method includes determining, upon receipt of a Physical Uplink Control Channel/Sounding Reference Signal (PUCCH/SRS) release request from a lower layer, whether configuration information required for a transmission mode supporting Coordinated Multi-Point (CoMP) has been configured, and if the configuration information has been configured, reconfiguring a setting state of the configuration information.

First claim

What is claimed is:

1. A method for configuring information for radio resource control by a terminal in a wireless communication system, the method comprising:
receiving a physical uplink control channel/sounding reference signal (PUCCH/SRS) release request from a lower layer; and
releasing channel quality indicator (CQI) report information associated with CQI configuration information specifying a CQI reporting configuration, wherein if transmission mode 10 is configured for a serving cell, the CQI report information comprises a set of periodic CQI related parameters.

2. The method of claim 1 , wherein if the transmission mode 10 is configured for the serving cell, the CQI report information further comprises at least one of a CSI-RS-ConfigNZP-r11, a CSI-IM-Config-r11, or a CSI-Process-r11.

3. The method of claim 2 , wherein the CSI-RS-ConfigNZP-r11 is configured to provide resource configuration information about a channel state information reference signal (CSI-RS) requiring non-zero transmission power.

4. The method of claim 2 , wherein the CSI-Process-r11 is configured to specify a reporting unit that the terminal uses to report the CQI.

5. The method of claim 2 , wherein the CSI-IM-Config-r11 is configured to provide resource configuration information about a channel state information-interference measurement (CSI-IM).

6. The method of claim 1 , wherein if at least one secondary cell is configured for the terminal, releasing the CQI configuration information for each of the at least one secondary cells.

7. A terminal configured to configure information for radio resource control in a wireless communication system, the terminal comprising:
a transceiver configured to receive a physical uplink control channel/sounding reference signal (PUCCH/SRS) release request from a lower layer; and
a controller configured to release channel quality indicator (CQI) report information associated with CQI configuration information specifying a CQI reporting configuration, wherein if transmission mode 10 is configured for a serving cell, the CQI report information comprises a set of periodic CQI related parameters.

8. The terminal of claim 7 , wherein if the transmission mode 10 is configured for the serving cell, the CQI reporting information further comprises at least one of a CSI-RS-ConfigNZP-r11, a CSI-IM-Config-r11, or a CSI-Process-r11.

9. The terminal of claim 8 , wherein the CSI-RS-ConfigNZP-r11 provides resource configuration information about a channel state information reference signal (CSI-RS) requiring non-zero transmission power.

10. The terminal of claim 8 , wherein the CSI-Process-HI is configured to specify a reporting unit that the terminal uses to report the CQI.

11. The terminal of claim 8 , wherein the CSI-IM-Config-r11 is configured to provide resource configuration information about a channel state information-interference measurement (CSI-IM).

12. The terminal of claim 7 , wherein if at least one secondary cell is configured for the terminal, the controller is configured to release the CQI configuration information for each of the at least one secondary cells.
