Abstract

Embodiments under the present disclosure include systems and methods for prioritization for SR and PUSCH without LCH association. For example, certain embodiments can comprise a method performed by a wireless device for priority handling of SR and PUSCH without LCH association. The method can comprise the wireless device determining that the SR and PUSCH are not related to a LCH and determining a priority of the SR and PUSCH.

Claims (32)

1 . A method performed by a wireless device for priority handling of scheduling request, SR, and physical uplink shared channel, PUSCH, without Logical Channel, LCH, association, the method comprising:

determining that the SR and PUSCH are not related to a LCH;

determining a priority of the SR and PUSCH; and

receiving the priority of the PUSCH associated with an aperiodic Channel State Information, CSI, report in a Radio Resource Control Information Element, RRC IE;

wherein, in response to determining that the SR and PUSCH are not related to a LCH, the priority of the SR and PUSCH is determined based on a priority of at least one Medium Access Control-Control Element, MAC CE, or based on a physical-index-based priority of the SR and PUSCH.

2 . The method of claim 1 , wherein the MAC CE comprises at least one of a Beam Failure Recovery, BFR, MAC CE or a Listen Before Talk, LBT, failure MAC CE.

3 . The method of claim 1 , wherein the priority of the SR and PUSCH is determined to be a high priority, and the method further comprises prioritizing the SR and PUSCH over an overlapping resource that has a lower priority than the high priority of the SR and PUSCH.

4 . The method of claim 1 , further comprising prioritizing the SR and PUSCH over a grant associated with a Medium Access Control Packet Data Unit, MAC PDU, that includes only padding.

5 . A wireless device for priority handling of scheduling request, SR, and physical uplink shared channel, PUSCH, without Logical Channel, LCH, association, the wireless device comprising:

processing circuitry configured to:

determine that the SR and PUSCH are not related to a LCH;

determine a priority of the SR and PUSCH; and

receive the priority of the PUSCH associated with an aperiodic Channel State Information, CSI, report in a Radio Resource Control Information Element, RRC IE;

wherein, in response to determining that the SR and PUSCH are not related to a LCH, the priority of the SR and PUSCH is determined based on a priority of at least one Medium Access Control-Control Element, MAC CE, or based on a physical-index-based priority of the SR and PUSCH.

6 . The wireless device of claim 5 , wherein the MAC CE comprises at least one of a Beam Failure Recovery, BFR, MAC CE or a Listen Before Talk, LBT, failure MAC CE.

7 . The wireless device of claim 5 , wherein the priority of the SR and PUSCH is determined to be a high priority, and the processing circuitry is configured to prioritize the SR and PUSCH over an overlapping resource that has a lower priority than the high priority of the SR and PUSCH.

8 . The wireless device of claim 5 , wherein the processing circuitry is configured to prioritize the SR and PUSCH over a grant associated with a Medium Access Control Packet Data Unit, MAC PDU, that includes only padding.

9 . A method performed by a network node for configuring a wireless device for priority handling of scheduling request, SR, and physical uplink shared channel, PUSCH, without Logical Channel, LCH, association, the method comprising:

configuring the wireless device to determine a priority of the SR and PUSCH when the SR and PUSCH are not related to a LCH;

transmitting the priority of the PUSCH associated with an aperiodic Channel State Information, CSI, report in a Radio Resource Control Information Element, RRC IE;

wherein, when the SR and PUSCH are not related to a LCH, the priority of the SR and PUSCH is determined based on a priority of at least one Medium Access Control-Control Element, MAC CE, or based on a physical-index-based priority of the SR and PUSCH.

10 . The method of claim 9 , wherein the priority of the SR and PUSCH is determined based on a priority of at least one Medium Access Control-Control Element, MAC CE.

11 . The method of claim 10 , wherein the MAC CE comprises at least one of a Beam Failure Recovery, BFR, MAC CE or a Listen Before Talk, LBT, failure MAC CE.

12 . The method of claim 9 , further comprising configuring the wireless device to prioritize the SR and PUSCH over an overlapping resource when the priority of the SR and PUSCH is determined to be of a higher priority than a priority of the overlapping resource.

13 . The method of claim 9 , further comprising configuring the wireless device to prioritize the SR and PUSCH over a grant associated with a Medium Access Control Packet Data Unit, MAC PDU, that includes only padding.

14 . A network node for configuring a wireless device for priority handling of scheduling request, SR, and physical uplink shared channel, PUSCH, without Logical Channel, LCH, association, the network node comprising:

processing circuitry configured to configure the wireless device to determine a priority of the SR and PUSCH when the SR and PUSCH are not related to a LCH, the processing circuitry further configured to perform the steps of;

transmitting the priority of the PUSCH associated with an aperiodic Channel State Information, CSI, report in a Radio Resource Control Information Element, RRC IE;

wherein, when the SR and PUSCH are not related to a LCH, the priority of the SR and PUSCH is determined based on a priority of at least one Medium Access Control-Control Element, MAC CE, or based on a physical-index-based priority of the SR and PUSCH.

15 . The network node of claim 14 , wherein the priority of the SR and PUSCH is determined based on a priority of at least one Medium Access Control-Control Element, MAC CE.

16 . The network node of claim 15 , wherein the MAC CE comprises at least one of a Beam Failure Recovery, BFR, MAC CE or a Listen Before Talk, LBT, failure MAC CE.

17 . The network node of claim 14 , wherein the processing circuitry is configured to configure the wireless device to prioritize the SR and PUSCH over an overlapping resource when the priority of the SR and PUSCH is determined to be of a higher priority than a priority of the overlapping resource.
