Abstract

Various aspects of the present disclosure provide for an apparatus configured for determining priority information associated with data traffic at an upper layer, mapping the data traffic to a queue at an intermediate layer based on the priority information determined at the upper layer, and mapping an endpoint associated with the queue to an access category (AC) at a lower layer based on the priority information determined at the upper layer. The priority information of the data traffic may be associated with a classification or type of data in the data traffic. The upper layer may be an application layer. The intermediate layer may be a protocol adaptation layer (PAL). The lower layer may be a media access control (MAC) layer. Various apparatuses, methods, computer-readable medium including similar features are also provided herein. Additional and alternative aspects, embodiments, and features are also provided herein.

First claim

1 . A method of wireless communication by an apparatus, the method comprising:
determining priority information associated with data traffic at an upper layer; mapping the data traffic to a queue at an intermediate layer based on the priority information determined at the upper layer; mapping an endpoint associated with the queue to an access category (AC) at a lower layer based on the priority information determined at the upper layer; and transmitting the data traffic from the lower layer to another apparatus.

2 . The method of claim 1 , wherein:
the upper layer is an application layer; the intermediate layer is a protocol adaptation layer (PAL); and the lower layer is a media access control (MAC) layer.

3 . The method of claim 1 , wherein two or more queues are associated with a single endpoint.

4 . The method of claim 1 , wherein each queue is associated with a dedicated endpoint.

5 . The method of claim 1 , wherein the AC comprises at least one of a voice AC, a video AC, a best effort AC, or a background AC.

6 . The method of claim 1 , wherein the endpoint comprises at least one of a bulk endpoint, an interrupt endpoint, a control endpoint, or an isochronous endpoint.

7 . The method of claim 1 , wherein the priority information of the data traffic is associated with a classification or type of data in the data traffic.

8 . The method of claim 1 , wherein:
the data traffic comprises a parameterized traffic stream; the mapping the data traffic comprises mapping the parameterized traffic stream to a dedicated queue at the intermediate layer; and the mapping the endpoint comprises mapping the parameterized traffic stream to a dedicated AC.

9 . The method of claim 1 , wherein:
a first portion of the data traffic at the upper layer is associated with first priority information and is mapped to a first queue at the intermediate layer based on the first priority information; a second portion of the data traffic at the upper layer is associated with second priority information and is mapped to a second queue at the intermediate layer based on the second priority information; and the first queue is different from the second queue.

10 . The method of claim 9 , wherein:
a first endpoint associated with the first queue at the intermediate layer is mapped to a first AC at the lower layer based on the first priority information; and a second endpoint associated with the second queue at the intermediate layer is mapped to a second AC at the lower layer based on the second priority information; and the first AC is different from the second AC.

11 . An apparatus for wireless communication, the apparatus comprising:
a memory; at least one processor coupled to the memory and configured to:
determine priority information associated with data traffic at an upper layer;
map the data traffic to a queue at an intermediate layer based on the priority information determined at the upper layer; and
map an endpoint associated with the queue to an access category (AC) at a lower layer based on the priority information determined at the upper layer; and
a transceiver configured to:
transmit the data traffic from the lower layer to another apparatus.

12 . The apparatus of claim 11 , wherein:
the upper layer is an application layer; the intermediate layer is a protocol adaptation layer (PAL); and the lower layer is a media access control (MAC) layer.

13 . The apparatus of claim 11 , wherein two or more queues are associated with a single endpoint.

14 . The apparatus of claim 11 , wherein each queue is associated with a dedicated endpoint.

15 . The apparatus of claim 11 , wherein the AC comprises at least one of a voice AC, a video AC, a best effort AC, or a background AC.

16 . The apparatus of claim 11 , wherein the endpoint comprises at least one of a bulk endpoint, an interrupt endpoint, a control endpoint, or an isochronous endpoint.

17 . The apparatus of claim 11 , wherein the priority information of the data traffic is associated with a classification or type of data in the data traffic.

18 . The apparatus of claim 11 , wherein:
the data traffic comprises a parameterized traffic stream; the mapping the data traffic comprises mapping the parameterized traffic stream to a dedicated queue at the intermediate layer; and the mapping the endpoint comprises mapping the parameterized traffic stream to a dedicated AC.

19 . The apparatus of claim 11 , wherein:
a first portion of the data traffic at the upper layer is associated with first priority information and is mapped to a first queue at the intermediate layer based on the first priority information; a second portion of the data traffic at the upper layer is associated with second priority information and is mapped to a second queue at the intermediate layer based on the second priority information; and the first queue is different from the second queue.

20 . The apparatus of claim 19 , wherein:
a first endpoint associated with the first queue at the intermediate layer is mapped to a first AC at the lower layer based on the first priority information; and a second endpoint associated with the second queue at the intermediate layer is mapped to a second AC at the lower layer based on the second priority information; and the first AC is different from the second AC.

21 . A computer-readable medium comprising code for:
