3 . The method of claim 1 , wherein the indication data associated with the future transmission is associated with a trigger message transmitted to a chipset of the WD, the trigger message indicating a time that a packet will be generated.

4 . The method of claim 1 , wherein the method further includes:

receiving a first uplink, UL, grant based at least on the SR on the periodic SR opportunity; and

transmitting at least a first UL packet and a first buffer status report, BSR, in response to receiving the first UL grant.

5 . The method of claim 4 , wherein the buffer status report, BSR, includes at least one of future data and non-causal data, the non-causal data being transmittable one of within the WD and to the network node.

6 . The method of claim 1 , wherein the method further includes:

determining generated uplink, UL, data for a transmission of at least one UL packet associated with the generated UL data, the generated UL data being generated by a WD application.

7 . The method of claim 1 , wherein the method further includes:

receiving a second uplink, UL, grant; and

transmitting at least the second UL packet and a second buffer status report, BSR.

8 . The method of claim 7 , wherein at least the second UL packet and the second buffer status report, BSR, are transmitted in response at least to receiving at least any one of the second uplink, UL, grant from the network node and generated UL data from a WD application.

9 . The method of claim 1 , wherein method further includes:

predicting traffic associated with the future transmission based in part on input received from a WD application.

10 . A method implemented in a network node configured to communicate with a wireless device, WD, the method comprising:

receiving a scheduling request, SR, on a periodic SR opportunity based at least on indication data associated with a future transmission, the SR being associated with a future time at which data for a future transmission from the WD will be available and an amount of data that will be available for the future transmission, the future transmission having a time offset that is based on at least one of: applying one or more optimization techniques or performing one or more interactions with a chipset of the WD, the indication data indicating the amount of data and a predetermined time for the future transmission, and the predetermined time being based on the future time at which the data will be available and the time offset; and

determining at least one uplink, UL, grant for the WD based at least in part on the received SR.

11 . The method of claim 10 , wherein the indication data associated with the future transmission is associated with a packet ping associated with the WD at a predetermined time based on a time offset, the time offset being determined based on the future transmission.

12 . The method of claim 10 , wherein the indication data associated with the future transmission is associated with a trigger message transmitted to a chipset of the WD, the trigger message indicating a time that a packet will be generated.

13 . The method of claim 10 , wherein the method further includes:

transmitting a first uplink, UL, grant based at least on the SR on the periodic SR opportunity; and

receiving at least a first UL packet and a first buffer status report, BSR, in response to the first UL grant.
