Apparatus and method for controlling coexistence interference within device in wireless communication system
The present invention provides an apparatus and a method for controlling coexistence interference within a device in a wireless communication system. The method discloses the following steps: performing triggering, in which a transmission, which is generated in a terminal, in a first frequency band of a first network system requests controlling of interference on a reception, which is generated in the terminal, in a second frequency band of a second network system; transmitting to a base station support information including information on a time section that can or cannot be used by the first network system of the second network system, due to the interference; and receiving from the base station reply information for accepting or denying interference control as a reply to the support information.
1. A method for coordinating in-device coexistence (IDC) interference by a user equipment, the method comprising:
detecting the IDC interference;
in response to detecting the IDC interference, generating a first message;
transmitting the first message to a base station;
receiving discontinuous reception (DRX) configuration information from the base station; and
performing a DRX operation based on the DRX configuration information;
wherein the first message comprises informantion indicating unusable subframes for uplink transmission.
2. The method of claim 1 , wherein the first message further comprises a list of one or more frequency bands affected by the IDC interference.
3. The method of claim 1 , wherein the first message further comprises information identifying a victim system.
4. The method of claim 1 , further comprising:
detecting a change in the IDC interference;
in response to detecting the change in the IDC interference,
generating a second message comprising DRX parameters; and
transmitting the second message to the base station.
5. A communication apparatus comprising:
a memory; and
a processor operably coupled to the memory,
wherein the processor, when executing program instructions stored in the memory, is configured to:
detect in-device coexistence (IDC) interference;
in response to detecting the IDC interference, generate a first message;
cause the communication apparatus to transmit the first message to a base station;
cause the communication apparatus to receive discontinuous reception (DRX) configuration information from the base station; and
cause the communication apparatus to perform a DRX operation based on the DRX configuration information;
wherein the first message comprises information indicationg unusable subframes for uplink transmission.
6. The communication apparatus of claim 5 , wherein the first message further comprises a list of one or more frequency bands affected by the IDC interference.
7. The communication apparatus of claim 5 , wherein the first message further comprises information identifying a victim system.
8. The communication apparatus of claim 5 , wherein the processor is further configured to:
detect a change in the IDC interference;
in response to detecting the change in the IDC interference,
generate a second message comprising DRX parameters; and
cause the communication apparatus to transmit the second message to the base station.
9. A device for a terminal, the device comprising:
a memory; and
a processor operably coupled to the memory,
wherein the processor, when executing program instructions stored in the memory, is configured to:
detect in-device coexistence (IDC) interference;
in response to detecting the IDC interference, generate a first message;
cause the terminal to transmit the first message to a base station;
cause the terminal to receive discontinuous reception (DRX) configuration information from the base station; and
cause the terminal to perform a DRX operation based on the DRX configuration information,
wherein the first message comprises information indicating unusable subframes for uplink transmission.
10. The device of claim 9 , wherein the first message further comprises a list of one or more frequency bands affected by the IDC interference.
11. The device of claim 9 , wherein the first message further comprises information identifying a victim system.
12. The device of claim 9 , wherein the processor is further configured to:
detect a change in the IDC interference;
in response to detecting the change in the IDC interference,
generate a second message comprising DRX parameters; and
cause the terminal to transmit the second message to the base station.
