Abstract

Apparatuses, methods, and systems are disclosed for determining a priority order based on uplink transmission parameters. One apparatus includes a receiver that receives an uplink grant corresponding to uplink transmission parameters that include an indication of a numerology and a transmission time interval length. The apparatus includes a processor that determines a priority order of multiple logical channels based on the uplink transmission parameters and a logical channel priority of the multiple logical channels. The processor assigns resources to logical channels of the multiple logical channels based on the priority order.

First claim

The invention claimed is:

1. An apparatus comprising:
a processor that:
indicates uplink transmission parameters to a medium access control layer, wherein the uplink transmission parameters correspond to an uplink grant, the uplink transmission parameters comprise an indication of a numerology and an uplink transmission duration, and the numerology comprises a subcarrier spacing; and
assigns, by the medium access control layer, resources allocated by the uplink grant to the logical channels based on the uplink transmission parameters and a logical channel priority of the plurality of logical channels, wherein each logical channel of the plurality of logical channels is configured with a set of numerologies allowed by the respective logical channel and a maximum uplink transmission duration.

2. The apparatus of claim 1 , wherein the numerology comprises an orthogonal frequency-division multiplexing symbol duration, a cyclic prefix duration, or some combination thereof.

3. The apparatus of claim 1 , wherein the processor assigns the resources allocated by the uplink grant to the logical channels based on the uplink transmission parameters and the logical channel priority of the plurality of logical channels by:
selecting a set of logical channels of the plurality of logical channels in response to a numerology parameter of each logical channel of the set of logical channels including the numerology and the maximum uplink transmission duration of each logical channel of the set of logical channels being greater than or equal to the uplink transmission duration; and
assigning resources to the logical channels of the set of logical channels based on a logical channel priority of each logical channel of the set of logical channels.

4. The apparatus of claim 3 , wherein the processor assigns the logical channels of the set of logical channels by ordering the logical channels of the set of logical channels in descending priority order.

5. The apparatus of claim 3 , wherein the numerology parameter comprises one or more numerologies.

6. The apparatus of claim 3 , wherein logical channels of the set of logical channels are prioritized over a medium access control control element.

7. The apparatus of claim 1 , wherein the indication of the numerology comprises an index corresponding to the numerology.

8. The apparatus of claim 1 , wherein a medium access control control element is transmittable on the uplink grant for any numerology and any uplink transmission duration.

9. The apparatus of claim 1 , wherein each logical channel of the plurality of logical channels is configured with a maximum numerology allowed by the respective logical channel and the maximum uplink transmission duration.

10. The apparatus of claim 1 , wherein the processor assigns the resources allocated by the uplink grant to the logical channels based on the uplink transmission parameters and the logical channel priority of the plurality of logical channels by:
selecting a set of logical channels of the plurality of logical channels in response to a maximum numerology of each logical channel of the set of logical channels being less or equal to the numerology and the maximum uplink transmission duration of each logical channel of the set of logical channels being greater than or equal to the uplink transmission duration; and
assigning resources to the logical channels of the set of logical channels based on a logical channel priority of each logical channel of the set of logical channels.

11. The apparatus of claim 1 , wherein the processor selects a scheduling request resource for transmission, and the scheduling request resource corresponds to a numerology being requested for uplink transmission.

12. The apparatus of claim 11 , wherein the processor selects the scheduling request resource according to a first numerology of a set of configured numerologies of a logical channel of the plurality of logical channels for which a buffer status report is triggered due to data becoming available for transmission.

13. The apparatus of claim 1 , wherein the receiver receives a plurality of uplink grants and determines an order for processing the plurality of uplink grants based on a number of logical channels of the plurality of logical channels configured with a numerology corresponding to a respective uplink grant of the plurality of uplink grants.

14. The apparatus of claim 1 , wherein the receiver receives a plurality of uplink grants and determines an order for processing the plurality of uplink grants based on a predefined numerology priority order.

15. The apparatus of claim 1 , wherein the receiver receives a plurality of uplink grants and determines an order for processing the plurality of uplink grants based on a predefined order, a signaled order, or some combination thereof.

16. A method comprising:
indicating uplink transmission parameters to a medium access control layer, wherein the uplink transmission parameters correspond to an uplink grant, the uplink transmission parameters comprise an indication of a numerology and an uplink transmission duration, and the numerology comprises a subcarrier spacing; and
assigning, by the medium access control layer, resources allocated by the uplink grant to the logical channels based on the uplink transmission parameters and a logical channel priority of the plurality of logical channels, wherein each logical channel of the plurality of logical channels is configured with a set of numerologies allowed by the respective logical channel and a maximum uplink transmission duration.

17. The method of claim 16 , wherein the numerology comprises an orthogonal frequency-division multiplexing symbol duration, a cyclic prefix duration, or some combination thereof.

18. The method of claim 16 , wherein assigning the resources allocated by the uplink grant to the logical channels based on the uplink transmission parameters and the logical channel priority of the plurality of logical channels comprises:
selecting a set of logical channels of the plurality of logical channels in response to a numerology parameter of each logical channel of the set of logical channels including the numerology and the maximum uplink transmission duration of each logical channel of the set of logical channels being greater than or equal to the uplink transmission duration; and
assigning resources to the logical channels of the set of logical channels based on a logical channel priority of each logical channel of the set of logical channels.

19. The method of claim 18 , wherein assigning the resources to the logical channels of the set of logical channels comprises ordering the logical channels of the set of logical channels in descending priority order.

20. The method of claim 18 , wherein the numerology parameter comprises one or more numerologies.

21. The method of claim 18 , wherein logical channels of the set of logical channels are prioritized over a medium access control control element.

22. The method of claim 16 , wherein the indication of the numerology comprises an index corresponding to the numerology.

23. The method of claim 16 , wherein a medium access control control element is transmittable on the uplink grant for any numerology and any uplink transmission duration.

24. The method of claim 16 , wherein each logical channel of the plurality of logical channels is configured with a maximum numerology allowed by the respective logical channel and the ma
