Abstract

Claims (49)

1. A method implemented in a wireless device, the method comprising:

receiving a priority indicator associated with a downlink control information, DCI, message, the DCI message being associated with one of an uplink-configured grant, UL-CG, configuration and a downlink-semipersistent assignment, DL-SPS, configuration;

determining a use of the priority indicator associated with the DCI message; and

using the priority indicator according to the determined use, the using of the priority indicator according to the determined use comprising using the priority indicator to determine a relative priority among one of a plurality of UL-CG configurations and a plurality of DL-SPS configurations having a same priority.

2. The method of claim 1 , wherein the priority indicator includes a field in the DCI message.

3. The method of claim 2 , further comprising:

receiving a radio resource control, RRC, parameter, the RRC parameter indicating a size of the priority indicator field in the DCI message.

4. The method of claim 3 , wherein the size corresponds to a number of bits between 0 and n, n being a number greater than 0.

5. The method of claim 2 , further comprising:

receiving a radio resource control, RRC, parameter, the RRC parameter indicating a size of a priority indicator field in a DCI message associated with a dynamic scheduling of the wireless device.

6. The method of claim 5 , wherein a size of the priority indicator field in the DCI message associated with the one of the UL-CG configuration and the DL-SPS configuration is a fixed size.

7. The method of claim 1 , wherein the RRC parameter is comprised in one of a physical uplink shared channel, PUSCH, configuration and a physical downlink shared channel, PDSCH, configuration.

8. The method of claim 1 , wherein determining the use comprises determining the use of the priority indicator based at least in part on at least one of:

a radio network temporary identifier associated with the DCI message, a search space associated with the DCI message, a control resource set, CORESET, associated with the DCI message, a DCI format of the DCI message and a size of the DCI message.

9. The method of claim 1 , wherein determining the use comprises determining the use of the priority indicator based at least in part on a pre-defined rule.

10. The method of claim 1 , further comprising:

using the priority indicator according to the determined use, using the priority indicator comprises one of:

using the priority indicator to determine whether the DCI message corresponds to an activation or a release of the one of the UL-CG configuration and the DL-SPS configuration; and;

using the priority indicator to validate one of an activation and a release of the one of the UL-CG configuration and the DL-SPS configuration;

using the priority indicator to validate one of an activation and a release of the one of the UL-CG configuration and the DL-SPS configuration; and

using the priority indicator to determine whether the DCI message corresponds to an activation/release of the one of the UL-CG configuration and the DL-SPS configuration, or a re-transmission request associated with the one of the UL-CG configuration and the DL-SPS configuration based at least in part on the priority indicator.

11. The method of claim 10 , wherein using the priority indicator comprises at least one of:

using the priority indicator to indicate a physical channel, PHY, priority to logical channel, LCH, priority mapping set;

using the priority indicator to indicate a DCI priority to logical channel, LCH, priority mapping set;

overriding a priority indicated by a radio resource control, RRC, priority parameter; and/or

using the priority indicator to indicate a parameter unrelated to priority.

12. The method of claim 1 , further comprising:

receiving a radio resource control, RRC, priority parameter associated with the one of the UL-CG configuration and the DL-SPS configuration.

13. The method of claim 1 , further comprising determining a relative priority order between at least two of:

a first priority indicated by a radio resource control, RRC, priority parameter associated with the one of the UL-CG configuration and the DL-SPS configuration;

a second priority indicated by the priority indicator in the DCI message;

a third priority for a re-transmission associated with the one of the UL-CG configuration and the DL-SPS configuration; and

a fourth priority for a dynamic transmission.

14. The method of claim 13 , further comprising determining the relative priority order based at least in part on a pre-defined rule.

15. The method of claim 13 , wherein the third priority for the re-transmission is a same as one of the second priority and the first priority.

16. The method of claim 1 , wherein the priority indicator includes at least one of:

a radio network temporary identifier associated with the DCI message, a search space associated with the DCI message, a control resource set, CORESET, associated with the DCI message, a DCI format of the DCI message and a size of the DCI message.

17. A method implemented in a network node, the method comprising:

determining a use of a priority indicator associated with a downlink control information, DCI, message;

using the priority indicator according to the determined use, the using of the priority indicator according to the determined use comprising using the priority indicator to determine a relative priority among one of a plurality of uplink-configured grant, UL-CG, configurations and a plurality of downlink-semipersistent assignment, DL-SPS, configurations having a same priority; and

sending the priority indicator associated with the DCI message according to the determined use, the DCI message being associated with one of an UL-CG configuration and a DL-SPS configuration.

18. A wireless device configured to communicate with a network node, the wireless device comprising processing circuitry, the processing circuitry configured to cause the wireless device to:

receive a priority indicator associated with a downlink control information, DCI, message, the DCI message being associated with one of an uplink-configured grant, UL-CG, configuration and a downlink-semipersistent assignment, DL-SPS, configuration;

determine a use of the priority indicator associated with the DCI message; and

using the priority indicator according to the determined use, the using of the priority indicator according to the determined use comprising using the priority indicator to determine a relative priority among one of a plurality of UL-CG configurations and a plurality of DL-SPS configurations having a same priority.

19. A network node configured to communicate with a wireless device, the network node comprising processing circuitry, the processing circuitry configured to cause the network node to:

determine a use of a priority indicator associated with a downlink control information, DCI, message;

using the priority indicator according to the determined use, the using of the priority indicator according to the determined use comprising using the priority indicator to determine a relative priority among one of a plurality of uplink-configured grant, UL-CG, configurations and a plurality of downlink-semipersistent assignment, DL-SPS, configurations having a same priority; and
