Method and apparatus for avoiding in-device coexistence interference with preferred frequency notification

A method for use in radio access network (eNB) to avoid interference between first and second radio components located on a single platform at a user equipment (UE), comprising:

• receiving a coexistence interference indication message as a Radio Resource Control (RRC) message, the coexistence interference indication message comprising one or more proposed control parameters for establishing a coexistence mode for the first and second radio components by specifying a preferred frequency notification for the first radio component, where the preferred frequency notification comprises at least one of a fixed frequency boundary which defines usable frequencies for the first radio component that will not interfere with the second radio component, a variable frequency boundary which defines usable frequencies for the first radio component that substantially reduces interfere with the second radio component, a frequency boundary which defines unusable frequencies for the first radio component that will interfere with the second radio component, or a transmission scheme used by the second radio component to implicitly specify a frequency band used by the second radio component;
• and
• sending, by the eNB, a response message comprising one or more control parameters for establishing a new frequency for the first radio component so that the first radio component at the UE can be enabled to use the new frequency without interference to/from the second radio component.

A computer program product comprising a non-transitory computer readable storage medium having computer readable program code embodied therein, the computer readable program code adapted to be executed to implement a method for operating user equipment (UE) in a coexistence mode, comprising:

• instructions for measuring at a first radio component in-device coexistence interference from a second radio component;
• instructions for sending a coexistence interference indication message as a Radio Resource Control (RRC) message, the coexistence interference indication message comprising one or more proposed control parameters for establishing a coexistence mode for the first and second radio components by specifying a preferred frequency notification for the first radio component, wherein the preferred frequency notification comprises at least one of a fixed frequency boundary which defines usable frequencies for the first radio component that will not interfere with the second radio component, a variable frequency boundary which defines usable frequencies for the first radio component that substantially reduces interfere with the second radio component, a frequency boundary which defines unusable frequencies for the first radio component that will interfere with the second radio component, or a transmission scheme used by the second radio component to implicitly specify a frequency band used by the second radio component;
• instructions for receiving a response message comprising one or more control parameters for establishing a new frequency for the first radio component;
• and
• instructions for enabling the first radio component with the one or more control parameters to use the new frequency without interference to/from the second radio component.

A user equipment device comprising first and second radio components on a single platform, comprising:

• a first radio component and a second radio component on a shared platform;
• and
• processor control circuitry configured to provide a preferred frequency notification for the first radio component to avoid in-device coexistence interference from the second radio component by:
• measuring at the first radio component in-device coexistence interference from the second radio component;
• sending a coexistence interference indication message as a Radio Resource Control (RRC) message, the coexistence interference indication message comprising one or more proposed control parameters for establishing a coexistence mode for the first and second radio components by specifying a preferred frequency notification for the first radio component wherein the preferred frequency notification comprises at least one of a fixed frequency boundary which defines usable frequencies for the first radio component that will not interfere with the second radio component, a variable frequency boundary which defines usable frequencies for the first radio component that substantially reduces interfere with the second radio component, a frequency boundary which defines unusable frequencies for the first radio component that will interfere with the second radio component, or a transmission scheme used by the second radio component to implicitly specify a frequency band used by the second radio component;
• and
• receiving a response message comprising one or more control parameters for establishing a new frequency for the first radio component.
