Abstract

Method and apparatus for controlling in-device coexistence (IDC) interference in a wireless communication system are described in the present invention. The present invention includes transmitting UE capability information whether the UE has a capability to measure IDC, to a base station (BS); receiving measurement configuration information whether the UE is allowed to send IDC indication, from the BS; and transmitting the IDC indication and at least one of measurements which are a measurement in consideration of IDC and a measurement without consideration of IDC to the BS. It is possible to control reducing occurrence of in-device coexistence interference.

Claims (39)

1. A method for avoiding an interference, comprising:

receiving, by a User Equipment (UE), In Device Coexistence (IDC) enabling information that indicates whether the UE is configured to initiate an IDC indication to a Base Station (BS) through a Radio Resource Control (RRC) connection reconfiguration message;

generating, by the UE, the IDC indication; and

transmitting, to the BS, the IDC indication including updated unusable frequency information and Time Division Multiplex (TDM) pattern information based on discontinuous reception (DRX) information and indicating an update on whether the UE is in an IDC entry situation or whether the UE is in an IDC release situation with a 1 or 2 bit IDC indicator,

wherein a pattern periodicity interval comprises a scheduled period interval and an unscheduled period interval to avoid the IDC interference based on the DRX.

2. The method of claim 1 , further comprising:

transmitting, to the BS, at least one of a measurement in consideration of IDC and a measurement without consideration of IDC.

3. The method of claim 1 , wherein the updated unusable frequency information includes information of an updated frequency associated with an IDC interference.

4. The method of claim 1 ,

wherein the IDC entry situation is determined based on a comparison of a measurement result which has considered IDC interference and a measurement result which has not considered IDC interference, and

wherein when the comparison is greater than a threshold, an event indicating that a state in which IDC interference is ongoing is triggered.

5. The method of claim 1 , further comprising:

determining whether IDC is ongoing in the UE; and

receiving an IDC control from the BS.

6. The method of claim 1 , wherein capability information of the UE is a one bit bitmap indicator indicating the UE supports IDC.

7. The method of claim 1 , wherein the updated unusable frequency information corresponds to information regarding an unusable frequency in which IDC is ongoing, and the TDM pattern information corresponds to information regarding an applicable Time Division Multiplex pattern.

8. A method for controlling an interference, comprising:

generating, by a Base Station (BS), IDC enabling information associated with a User Equipment (UE);

transmitting, from the BS to the UE, the IDC enabling information that indicates whether the UE is configured to initiate an IDC indication to BS through a Radio Resource Control (RRC) connection reconfiguration message; and

receiving the IDC indication from the UE, the IDC indication including updated unusable frequency information and Time Division Multiplex (TDM) pattern information based on discontinuous reception (DRX) information and indicating an update on whether the UE is in an IDC entry situation or whether the UE is in an IDC release situation with a 1 or 2 bit IDC indicator,

wherein a pattern periodicity interval comprises a scheduled period interval and an unscheduled period interval to avoid the IDC interference based on the DRX.

9. The method of claim 8 , further comprising:

receiving, by the BS, at least one of a measurement in consideration of IDC and a measurement without consideration of IDC from the UE.

10. The method of claim 8 , wherein the IDC entry situation is determined based on a comparison of a measurement result which has considered IDC interference and a measurement result which has not considered IDC interference, and

wherein when the comparison is greater than a threshold, an event indicating that a state in which IDC interference is ongoing is triggered.

11. A User Equipment (UE) for avoiding an interference in a wireless communication system, the UE comprising:

a receiver to receive, from a Base Station (BS), IDC enabling information that indicates whether the UE is allowed to send an IDC indication;

a processor to generate the IDC indication; and

a transmitter to transmit the IDC indication including updated unusable frequency information and Time Division Multiplex (TDM) pattern information based on discontinuous reception (DRX) information and indicating an update on whether the UE is in an IDC entry situation or whether the UE is in an IDC release situation with a 1 or 2 bit IDC indicator,

wherein a pattern periodicity interval comprises a scheduled period interval and an unscheduled period interval to avoid the IDC interference based on the DRX.

12. The UE of claim 11 , wherein the transmitter transmits at least one of a measurement in consideration of IDC and a measurement without consideration of IDC to the BS.

13. The UE of claim 11 , wherein the updated unusable frequency information includes information of an updated frequency associated with an IDC interference.

14. The UE of claim 11 , wherein the IDC entry situation is determined based on a comparison of a measurement result which has considered IDC interference and a measurement result which has not considered IDC interference, and

wherein when the comparison is greater than a threshold, an event indicating that a state in which IDC interference is ongoing is triggered.

15. The UE of claim 12 , further comprising:

a controller to determine whether IDC is ongoing in the UE,

wherein the receiver receives an IDC control from the BS.

16. The UE of claim 11 , wherein capability information of the UE is a one bit bitmap indicator indicating the UE supports IDC.

17. The UE of claim 11 , wherein the updated unusable frequency information corresponds to information regarding an unusable frequency in which IDC is ongoing, and the TDM pattern information corresponds to information regarding an applicable Time Division Multiplex pattern.
