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

摘要

A method, system and device are provided for avoiding in-device coexistence interference between different radio technologies deployed in adjacent bands on the same device by providing preferred frequency solutions for the in-device coexistence system.

1. A method for use in user equipment (UE) device comprising first and second radio components on a single platform, comprising:
measuring, by the UE, 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.
