A method of operating a user equipment in a radio access network, the method comprising:
- determining a number of bits of Hybrid Acknowledgement Repeat Request (HARQ) feedback to be transmitted;
- transmitting Physical Uplink Shared Channel (PUSCH) data in a PUSCH transmission;
- and
- multiplexing the HARQ feedback in the PUSCH transmission, the PUSCH data and the HARQ feedback being multiplexed according to one of:
- puncturing the HARQ feedback into the PUSCH data based on the determined number of bits of HARQ feedback to be transmitted being less than or equal to a preconfigured size threshold of 2 bits;
- and
- rate-matching the PUSCH data around the HARQ feedback based on the determined number of bits of HARQ feedback to be transmitted being greater than the preconfigured size threshold of 2 bits.
A user equipment for a radio access network, the user equipment being configured to:
- determine a number of bits of Hybrid Acknowledgement Repeat Request (HARQ) feedback to be transmitted;
- transmit Physical Uplink Shared Channel (PUSCH) data in a PUSCH transmission;
- and
- multiplex the HARQ feedback in the PUSCH transmission, the PUSCH data and the HARQ feedback being multiplexed according to one of:
- puncturing the HARQ feedback into the PUSCH data based on the determined number of bits of HARQ feedback to be transmitted being less than or equal to a preconfigured size threshold of 2 bits;
- and
- rate-matching the PUSCH data around the HARQ feedback based on the determined number of bits of HARQ feedback to be transmitted being greater than the preconfigured size threshold of 2 bits.
A method of operating a radio node in a radio access network, the method comprising:
- determining a number of bits of Hybrid Acknowledgement Repeat Request (HARQ) feedback to be received;
- receiving Physical Uplink Shared Channel (PUSCH) data in a PUSCH transmission;
- receiving HARQ feedback in the PUSCH transmission according to a HARQ feedback format, the PUSCH data and the HARQ feedback being multiplexed according to one of:
- puncturing the HARQ feedback into the PUSCH data based on the determined number of bits of HARQ feedback to be received being less than or equal to a preconfigured size threshold of 2 bits;
- and
- rate-matching the PUSCH data around the HARQ feedback based on the determined number of bits of HARQ feedback to be received being greater than the preconfigured size threshold of 2 bits.
A radio node for a radio access network, the radio node being configured to:

- puncturing the HARQ feedback into the PUSCH data based on the determined number of bits of HARQ feedback to be received being less than or equal to a preconfigured size threshold of 2 bits;
- and
- rate-matching the PUSCH data around the HARQ feedback based on the determined number of bits of HARQ feedback to be received being greater than the preconfigured size threshold of 2 bits.
A non-transitory computer storage medium storing an executable computer program comprising instructions that, when executed, cause processing circuitry to at least one of control and perform a method of operating a user equipment in a radio access network, the method comprising:
- determining a number of bits of Hybrid Acknowledgement Repeat Request (HARQ) feedback to be transmitted;
- transmitting Physical Uplink Shared Channel (PUSCH) data in a PUSCH transmission;
- and
- multiplexing the HARQ feedback in the PUSCH transmission, the PUSCH data and the HARQ feedback being multiplexed according to one of:
- puncturing the HARQ feedback into the PUSCH data based on the determined number of bits of HARQ feedback to be transmitted being less than or equal to a preconfigured size threshold of 2 bits;
- and
- rate-matching the PUSCH data around the HARQ feedback based on the determined number of bits of HARQ feedback to be transmitted being greater than the preconfigured size threshold or 2 bits.
