Abstract

A method performed by a wireless device for mapping data to specific HARQ processes is provided. The method includes receiving an indication that maps data that can be sent on one or more of specific HARQ processes and transmitting/receiving a transmission for the specific HARQ process based on the received indication. A method performed by a base station for mapping data to specific HARQ processes is also provided. A wireless device and a base station for mapping data to specific HARQ processes are also provided.

First claim

What is claimed is:

1. A method performed by a wireless device for mapping data to specific HARQ processes, the method comprising:
receiving an indication that maps data that can be sent on one or more of specific HARQ processes; and
transmitting a transmission for a specific HARQ process of the one or more specific HARQ processes based on the received indication, such that;
when the indication comprises a parameter for logical channel prioritization (LCP), a restriction applies to logical channels such that only data from specific logical channels are included that are allowed to send data on HARQ processes with a HARQ procedure disabled, based on the received indication; and
when the indication does not comprise the parameter for logical channel prioritization, the wireless device interprets that logical channels are allowed to send data on the specific HARQ process without said restriction.

2. The method of claim 1 wherein the indication is provided by radio resource control (RRC) signaling.

3. A method performed by a base station, the method comprising:
determining an indication for mapping data; and
sending to a wireless device an indication that maps data that can be sent on one or more of specific HARQ processes, such that:
when the indication comprises a parameter for logical channel prioritization (LCP), a restriction applies to logical channels such that only data from specific logical channels are included that are allowed to send data on HARQ processes with a HARQ procedure disabled, based on the received indication; and
when the indication does not comprise the parameter for logical channel prioritization, the wireless device is enabled to interpret that logical channels are allowed to send data on the specific HARQ process without said restriction.

4. The method of claim 1 , wherein the indication is provided by radio resource control (RRC) signaling.

5. A wireless device for mapping data to specific HARQ processes, the wireless device comprising processing circuitry configured to:
receive an indication that maps data that can be sent on one or more of specific HARQ processes; and
transmit a transmission for a specific HARQ process of the one or more specific HARQ processes based on the received indication, such that;
when the indication comprises a parameter for logical channel prioritization (LCP), a restriction applies to logical channels such that only data from specific logical channels are included that are allowed to send data on HARQ processes with a HARQ procedure disabled, based on the received indication; and
when the indication does not comprise the parameter for logical channel prioritization, the wireless device interprets that logical channels are allowed to send data on the specific HARQ process without said restriction.

6. The wireless device of claim 5 wherein the indication is provided by radio resource control (RRC) signaling.

7. The method of claim 1 , wherein the method is for communication with a non-terrestrial network.

8. The method of claim 1 , wherein the method is for communication with a non-terrestrial network supported in new radio (NR).

9. The wireless device of claim 5 , wherein the wireless device is for communication with a non-terrestrial network.

10. The wireless device of claim 5 , wherein the wireless device is for communication with a non-terrestrial network supported in new radio (NR).

11. A base station comprising processing circuitry configured to:
determine an indication for mapping data; and
send to a wireless device an indication that maps data that can be sent on one or more of specific HARQ processes such that:
when the indication comprises a parameter for logical channel prioritization, a restriction applies to logical channels such that only data from specific logical channels are included that are allowed to send data on HARQ processes with a HARQ procedure disabled, based on the received indication; and
when the indication does not comprise the parameter for logical channel prioritization, the wireless device is enabled to interpret that logical channels are allowed to send data on the specific HARQ process without said restriction.

12. The base station of claim 11 , wherein the base station is for use in a non-terrestrial network.

13. The base station of claim 11 , wherein the base station is for use in a non-terrestrial network supported in New Radio (NR).

14. The base station of claim 11 , wherein the indication is provided by Radio Resource Control (RRC) signaling.
