send the user data and the self-organizing network measurement information together in the message to the base station, when it is determined that the self-organizing network measurement information can be accommodated in the message together with the user data.

2. The apparatus of claim 1 , wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus to:

compare the total size of the self-organizing network measurement information and the user data with the allocated transport block size for the message, when determining whether the self-organizing network measurement information can be accommodated in the message together with the user data.

3. The apparatus of claim 1 , wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus to:

send an indication to the base station that the apparatus has self-organizing network measurement information to send, without sending the self-organizing network measurement information along with the indication, when it is determined that the self-organizing network measurement information cannot be accommodated in the message together with the user data.

4. The apparatus of claim 1 , wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus to:

in response to determining that the apparatus has no user data to transmit to a base station, send the self-organizing network measurement information to the base station at a predetermined time as part of an early data transmission.

5. The apparatus of claim 1 , wherein the message comprises a radio resource control early data request message, or a radio resource control connection resume request message, or a media access control element, sent as part of early data transmission.

6. The apparatus of claim 1 , wherein the self-organizing network comprises a narrowband internet of things network.

7. 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 to, with the at least one processor, cause the apparatus at least to:

send to a user equipment an indication that reporting by the user equipment of self-organizing network measurement information together in a message with user data is supported by the apparatus; and in response to the indication, receive self-organizing network information together in the message with the user data from the user equipment, wherein the self-organizing network measurement information can be accommodated in the message together with the user data when a total size of the self-organizing network measurement information and the user data is within an allocated transport block size for the message.

8. The apparatus of claim 7 , wherein the indication to the user equipment comprises indicating one or more report types to the user equipment, the one or more report types comprising information of a preference of the apparatus for receiving the self-organizing network measurement information.

9. The apparatus of claim 7 , wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus to:

receive the message as a radio resource control early data request message, or a radio resource control connection resume request message, or a media access control control element, received as part of early data transmission.

10. The apparatus of claim 7 , wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus at least to:

receive from the user equipment an indication that the user equipment has self-organizing network measurement information to send, without receiving the self-organizing network measurement information along with the indication.

11. The apparatus of claim 7 , wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus to:

configure a maximum transport block size for reporting of the self-organizing network measurement information, the configuring a maximum transport block size comprising selecting the maximum transport block size from a plurality of available transport block sizes.

12. The apparatus of claim 7 , wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus to:

blindly decode the received self-organizing network measurement information.

13. The apparatus of claim 7 , wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus to:

blindly decode self-organizing network measurement information received from multiple user equipment.

14. A method comprising:

receiving, by a user equipment, from a base station an indication that reporting by the user equipment of self-organizing network measurement information in a message together with user data is supported by the base station;

performing self-organizing network measurements at the user equipment to generate the self-organizing network measurement information; and

in response to determining that the user equipment has user data to transmit to the base station, determining whether the self-organizing network measurement information can be accommodated in the message together with the user data, wherein it is determined that the self-organizing network measurement information can be accommodated in the message together with the user data when a total size of the self-organizing network measurement information and the user data is within an allocated transport block size for the message; and

sending the user data and the self-organizing network measurement information together in the message to the base station, when it is determined that the self-organizing network measurement information can be accommodated in the message together with the user data.

15. The method of claim 14 , further comprising comparing the total size of the self-organizing network measurement information and the user data with the allocated transport block size for the message, when determining whether the self-organizing network measurement information can be accommodated in the message together with the user data.

16. The method of claim 14 , further comprising sending by the apparatus an indication to the base station that the user equipment has self-organizing network measurement information to send, without sending the self-organizing network measurement information along with the indication, when it is determined that the self-organizing network measurement information cannot be accommodated in the message together with the user data.
