Abstract

Claims (42)

1. An apparatus for a network access node, the apparatus comprising:

at least one processor; and

at least one memory storing instructions that, when executed with the at least one processor, cause the apparatus to perform:

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.

2. An apparatus as claimed in claim 1 , wherein the instructions, when executed with the at least one processor, cause the apparatus to perform:

causing the first modulation and coding scheme to be used for transmissions made during at least one subband full duplex slot; and

causing the second modulation and coding scheme to be used for transmissions made during an uplink-only slot or during a downlink-only slot.

3. An apparatus as claimed in claim 1 , wherein the instructions, when executed with the at least one processor, cause the apparatus to perform:

determining first acknowledgement and negative acknowledgment information for signals received during subband full duplex slots; and

calculating the first offset value based on the first acknowledgment and negative acknowledgement information.

4. An apparatus as claimed in claim 1 , wherein the instructions, when executed with the at least one processor, cause the apparatus to perform receiving the first signal-to-interference and noise ratio from the terminal.

5. An apparatus as claimed in claim 1 , wherein the instructions, when executed with the at least one processor, cause the apparatus to perform receiving the first signal-to-interference and noise ratio in at least one of a channel quality indicator report or a channel state indicator.

6. An apparatus as claimed in claim 1 , wherein the instructions, when executed with the at least one processor, cause the apparatus to perform:

determining second acknowledgement and negative acknowledgment information for signals received during uplink-only slots or downlink-only slots; and

calculating the second offset value based on the second acknowledgment and negative acknowledgement information.

7. An apparatus as claimed in claim 6 , wherein the instructions, when executed with the at least one processor, cause the apparatus to perform:

adjusting a second signal-to-interference and noise ratio measured during the uplink-only slots or downlink-only slots using the second offset value to form a second adjusted signal-to-interference and noise ratio; and

determining the second modulation and coding scheme using the second adjusted signal-to-interference and noise ratio.

8. An apparatus as claimed in claim 7 , wherein the instructions, when executed with the at least one processor, cause the apparatus to perform receiving the second signal-to-interference and noise ratio from the terminal.

9. An apparatus as claimed in claim 7 , wherein the instructions, when executed with the at least one processor, cause the apparatus to perform receiving the second signal-to-interference and noise ratio in at least one of a channel quality indicator report or a channel state indicator.

10. An apparatus as claimed in claim 1 , wherein the first and second offset values are used during outer loop link adaptation mechanisms.

11. An apparatus as claimed during claim 1 , wherein the transmission power used for downlink transmissions made during the subband full duplex slots is different to the transmission power used for downlink transmissions made during the downlink-only slots.

12. 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.

13. 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.

14. An apparatus as claimed in claim 1 , wherein the terminal-specific correction offset values are outer loop link adaptation offset values.
