Method, apparatuses and computer program for reporting in-device coexistence information

A method, comprising

• performing operations in a network entity for control for carrier aggregation of at least one device with coexisting radios, wherein for carrier aggregation one radio of
• the at least one device connects to a primary cell corresponding to the network entity and another radio of the at least one device connects to a secondary cell, the operations comprising
• storing interference information received from the at least one device in response to a changed activation status of a secondary cell, wherein the interference information comprises in-device coexistence interference information,
• determining, after the storing, a new change in the activation status of the secondary cell,
• determining whether new interference information is received in response to the new change in the activation status of the secondary cell, and
• using the stored interference information in the control of the at least one device for carrier aggregation in response to a determination that no new interference information is received subsequent to the new change in the activation status of the secondary cell, and wherein interference information is reported in response to the change in the activation status only when there is different information content to be reported compared to previous reporting for similar change.

An apparatus comprising at least one processor, and at least one memory including computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to

• perform operations for a device with coexisting radios, wherein for carrier aggregation one radio connects to a primary cell and another radio connects to a secondary cell, the operations comprising:
• determine a change in the activation status of the secondary cell,
• determine interference information to be reported in response to the determined change in the activation status of the secondary cell, wherein the interference information comprises in-device coexistence interference information,
• compare the determined interference information to be reported to interference information reported previously for a similar change in the activation status of the secondary cell,
• decide whether to send the determined interference information based on the comparison, and
• decide to send and send the determined interference information in response to the change in the activation status only when there is different information content to be reported compared to previous reporting for a similar change, wherein the determined interference information is for use by the network element for control of the device for carrier aggregation.
