CLAIMS

What is claimed is:

1. A method in a wireless device, comprising:

- triggering a Sidelink (SL) Buffer Status Report (BSR) in response to data to be sent over the SL;

- triggering a Sidelink (SL) Scheduling Request (SR) for transmitting the SL BSR, wherein the SL BSR is intended to be transmitted by using a first uplink (UL) grant triggered by the SL SR; and

- cancelling the SL SR transmission if the SL BSR has been transmitted by using a second UL grant triggered by other sources.

2. The method according to claim 1 , wherein the SL BSR has been transmitted by using the second UL grant triggered by the Uu SR,

wherein the Uu SR is triggered by a Uu BSR, which is triggered in turn by data to be sent over the Uu interface.

3. The method according to claim 2, wherein the SL BSR and the Uu BSR has been transmitted together by using the second UL grant triggered by the Uu SR.

4. The method according to claim 2 or 3, further comprising:

- determining Logical Channel Prioritization (LCP) for at least the Uu BSR and the SL BSR; and

- transmitting the Uu BSR and/or the SL BSR according to the determined LCP.

5. The method according to claim 4, wherein the LCP is determined based on Quality of Service (QoS) requirement of the Uu BSR and the SL BSR,

wherein the QoS requirement includes priority requirement and/or latency requirement.

6. The method according to claim 5, wherein the QoS requirement of the Uu BSR is the highest QoS requirement of the logical channels included in the Uu BSR; and the QoS requirement of the SL BSR is the highest QoS requirement of the logical channels included in the SL BSR.

7. The method according to claim 5 or 6, wherein the SL BSR is prioritized over the Uu BSR if the QoS requirement of the SL BSR is higher than the QoS requirement of the Uu BSR.

8. The method according to any one of claims 5 to 7, wherein the SL BSR is prioritized over the Uu BSR if the QoS requirement of the SL BSR is higher than a threshold.

9. The method according to any one of claims 5 to 7, wherein the Uu BSR is prioritized over the SL BSR if the QoS requirement of the Uu BSR is higher than a threshold.

10. The method according to claim 8 or 9, wherein the threshold is preconfigured or configured by a network node via common or dedicated signalling.

11. The method according to claim 1 , wherein the SL BSR has been transmitted by using a third UL grant triggered by a second SL SR with a different configuration.

12. The method according to claim 1 , wherein the SL SR is transmitted without being cancelled, and the SL BSR and/or the Uu BSR is transmitted by using the first UL grant triggered by the Uu SR.

13. A wireless device, comprising:

at least one processor; and

a non -transitory computer readable medium coupled to the at least one processor, the non -transitory computer readable medium contains instructions executable by the at least one processor, whereby the at least one processor is configured to:

- trigger a Sidelink (SL) Buffer Status Report (BSR) in response to data to be sent over the SL;

- trigger a Sidelink (SL) Scheduling Request (SR) for transmitting the SL BSR, wherein the SL BSR is intended to be transmitted by using a first uplink (UL) grant triggered by the SL SR; and

- cancel the SL SR transmission if the SL BSR has been transmitted by using a second UL grant triggered by other sources.

14. The wireless device according to claim 13, wherein the SL BSR has been transmitted by using the second UL grant triggered by the Uu SR,

wherein the Uu SR is triggered by a Uu BSR, which is triggered in turn by data to be sent over the Uu interface.

15. The wireless device according to claim 14, wherein the SL BSR and the Uu BSR has been transmitted together by using the second UL grant triggered by the Uu SR.

16. The wireless device according to claim 14 or 15, the at least one processor is further configured to:

- determine Logical Channel Prioritization (LCP) for at least the Uu BSR and the SL BSR; and

- transmit the Uu BSR and/or the SL BSR according to the determined

LCP.

17. The wireless device according to claim 16, wherein the LCP is determined based on Quality of Service (QoS) requirement of the Uu BSR and the SL BSR,

wherein the QoS requirement includes priority requirement and/or latency requirement.

18. The wireless device according to claim 17, wherein the QoS requirement of the Uu BSR is the highest QoS requirement of the logical channels included in the Uu BSR; and the QoS requirement of the SL BSR is the highest QoS requirement of the logical channels included in the SL BSR.

19. The wireless device according to claim 17 or 18, wherein the SL BSR is prioritized over the Uu BSR if the QoS requirement of the SL BSR is higher than the QoS requirement of the Uu BSR.

20. The wireless device according to any one of claims 17 to 19, wherein the SL BSR is prioritized over the Uu BSR if the QoS requirement of the SL BSR is higher than a threshold.

21. The wireless device according to any one of claims 17 to 19, wherein the Uu BSR is prioritized over the SL BSR if the QoS requirement of the Uu BSR is higher than a threshold.

22. The wireless device according to claim 20 or 21 , wherein the threshold is preconfigured or configured by a network node via common or dedicated signalling.

23. The wireless device according to claim 13, wherein the SL BSR has been transmitted by using a third UL grant triggered by a second SL SR with a different configuration.

24. The wireless device according to claim 13, wherein the SL SR is transmitted without being cancelled, and the SL BSR and/or the Uu BSR is transmitted by using the first UL grant triggered by the Uu SR.

25. A computer readable medium comprising computer readable code, which when run on an apparatus, causes the apparatus to perform the method according to any one of claims 1 -12.
