TS-0026 Error behavior missing when MT request size is greater than maxPacketSize
In TS-0026 4.5, clause 7.1.1.2, Step 2: IN-CSE determines to issue a SCEF-based Mobile Terminated NIDD Downlink Data Transfer Request The IN-CSE shall only issue a SCEF-based Mobile Terminated (MT) NIDD Downlink Data Transfer Request if the NIDD Configuration Request for the targeted ASN/MN-CSE or ADN-AE hosted on a UE was successful and the size of the oneM2M request primitive to be sent in the MT NIDD Request is less than or equal to the maximumPacketSize defined in the NIDD Configuration response.
When request is intended for a 3GPP UE but it could not be sent due to above error (i.e. MT packet size > maxPacketSize) then what error should be returned to the originator?
