Proposal

We propose to use both the MACS and Codec/Model Size to characterize ULBC complexity and set complexity, RAM and ROM respectively for ULBC as below:

Complexity: single Model Size < 3M parameters and < 600MMACS.

RAM: < 3M parameters.

ROM: < 15M parameters.

And it is proposed to agree the following changes to the TR 26.940.
