Method, apparatus and computer program

A method for an apparatus for a network access node, the method comprising:

• calculating for a terminal a first offset value based on first acknowledgment and negative acknowledgement information for signals received during subband full duplex slots;
• calculating for the terminal a second offset value based on second acknowledgement and negative acknowledgment information for signals received during uplink-only slots or during downlink-only slots;
• using the first and second offset values to determine respective first and second modulation and coding schemes to be used with the terminal for transmissions made in a subband full duplex slots and either uplink-only slots or downlink-only slots;
• wherein the first offset value and the second offset value are terminal-specific correction offset values;
• adjusting a first signal-to-interference and noise ratio measured during the uplink-only slots or downlink-only slots using the first offset value to form a first adjusted signal-to-interference and noise ratio;
• and
• determining a first modulation and coding scheme using the first adjusted signal-to- interference and noise ratio.

A non-transitory program storage device readable with an apparatus, tangibly embodying a program of instructions executable with the apparatus for performing operations, the operations comprising:

• calculating for a terminal a first offset value based on first acknowledgment and negative acknowledgement information for signals received during subband full duplex slots;
• calculating for the terminal a second offset value based on second acknowledgement and negative acknowledgment information for signals received during uplink-only slots or during downlink-only slots;
• and
• using the first and second offset values to determine respective first and second modulation and coding schemes to be used with the terminal for transmissions made in a subband full duplex slots and either uplink-only slots or downlink-only slots;
• wherein the first offset value and the second offset value are terminal-specific correction offset values;
• adjusting a first signal-to-interference and noise ratio measured during the uplink-only slots or downlink-only slots using the first offset value to form a first adjusted signal-to-interference and noise ratio;
• and
• determining a first modulation and coding scheme using the first adjusted signal-to-interference and noise ratio.
