Enabling redcap wireless devices with reduced maximum data rate

A method implemented in a wireless device configured to communicate with a network node, the method comprising:

• receiving a first indication from the network node indicating a first restriction, the first restriction being related to a maximum data rate computation for at least one carrier and being different from a legacy restriction;
• causing transmission of a second indication to the network node indicating a plurality of capability parameters, the plurality of capability parameters violating the legacy restriction and being in accordance with the first restriction;
• communicating with the network node on the at least one carrier in accordance with a maximum data rate associated with the indicated plurality of capability parameters;
• the plurality of capability parameters includes at least one of:
• a maximum number of supported multiple-input-multiple-output, MIMO, layers;
• a scaling factor;
• and
• a maximum supported modulation order;
• the legacy restriction restricts a product of the maximum number of supported MIMO layers, the scaling factor, and the maximum supported modulation order to be greater than 4;
• and
• the first restriction restricts the product to be greater than 1.
