Method and apparatus for reporting in-device coexistence information in wireless mobile communication system
View Patent ↗A method for in-device coexistence information reporting is provided. The method includes receiving from a base station a first Radio Resource Control (RRC) message, transmitting a second RRC message, the second RRC message includes an in-device coexistence information, receiving a third RRC message, and applying a configuration based on the third RRC message. A first in-device coexistence information is included in the second RRC message if the first RRC message includes a first information, the first in-device coexistence information includes information related to frequency domain, the first information configures the terminal to report in-device coexistence information related to frequency domain. A second in-device coexistence information is included in the second RRC message if the first RRC message includes a second information, the second in-device coexistence information includes information related to time pattern, the second information configures the terminal to report in-device coexistence information related to time pattern.
1 . A method by a terminal in a wireless communication system, the method comprising:
receiving by the terminal from a base station a first Radio Resource Control (RRC) message, wherein the first RRC message comprises two parameters for in-device coexistence (IDC) assistance configuration, including:
a first parameter related to frequency-specific IDC assistance configuration, and
a second parameter related to time-specific IDC assistance configuration; and
transmitting by the terminal to the base station a second RRC message in case that in-device coexistence problem is detected,
wherein the second RRC message comprises:
a parameter indicating a list of specific combinations, each of which consists of two or more bandwidth portions related to inter-modulation distortion,
a parameter indicating victim system, and
a parameter related to slot pattern.
2 . A terminal in a wireless communication system, the terminal comprising:
a transceiver configured to transmit and receive a signal; and
