Abstract

There is disclosed a method of operating a user equipment in a radio access network. The method includes transmitting control information utilizing a control information format, the control information format being selected from a plurality of different control information formats based on a format indication. The disclosure also pertains to related devices and methods.

Claims

1. A method of operating a user equipment in a New Radio (NR) radio access network, the method comprising transmitting Hybrid Acknowledgement Repeat Request (HARQ) feedback in a Physical Uplink Shared Channel (PUSCH) transmission, the HARQ feedback being mapped to resources of the PUSCH transmission based on one of puncturing and rate-matching based on the number of bits of HARQ feedback to be transmitted.

2. The method according to claim 1, wherein the number of bits is indicated by a format indication.

3. The method according to claim 2, wherein the format indication is received in a scheduling grant scheduling the resources for the PUSCH transmission.

4. The method according to claim 1, wherein the HARQ feedback is punctured if the number of bits is a number up to a threshold number X of bits, and is rate-matched if the number of bits is above X.

5. The method according to claim 4, wherein X is predefined.

6. A user equipment for a New Radio (NR) radio access network, the user equipment comprising:

processing circuitry and radio circuitry, the user equipment being configured to utilize the processing circuitry and radio circuitry to;

transmit Hybrid Acknowledgement Repeat Request (HARQ) feedback in a Physical Uplink Shared Channel (PUSCH) transmission, the HARQ feedback being mapped to resources of the PUSCH transmission based on one of puncturing and rate-matching based on the number of bits of HARQ feedback to be transmitted.

7. The user equipment according to claim 6, wherein the number of bits is indicated by a format indication.

8. The user equipment according to claim 7, wherein the format indication is received in a scheduling grant scheduling the resources for the PUSCH transmission.

9. The user equipment according to claim 6, wherein the HARQ feedback is punctured if the number of bits is a number up to a threshold number X of bits, and is rate-matched if the number of bits is above X.

10. The user equipment according to claim 9, wherein X is predefined.

11. A network node for a New Radio (NR) radio access network, the network node comprising:

processing circuitry and radio circuitry, the network node being configured to utilize the processing circuitry and radio circuitry to;

receive Hybrid Acknowledgement Repeat Request (HARQ) feedback transmitted by a user equipment in a Physical Uplink Shared Channel (PUSCH) transmission, the HARQ feedback being mapped to resources of the PUSCH transmission based on one of puncturing and rate-matching based on the number of bits of HARQ feedback to be transmitted.

12. The network node according to claim 11, wherein the number of bits is indicated by a format indication.

13. The network node according to claim 12, wherein the format indication is received in a scheduling grant scheduling the resources for the PUSCH transmission.

14. The network node according to claim 11, wherein the HARQ feedback is punctured if the number of bits is a number up to a threshold number X of bits, and is rate-matched if the number of bits is above X.

15. The network node according to claim 14, wherein X is predefined.
