Abstract

Certain aspects of the present disclosure relate to methods and apparatus for quality of service (QoS) configuration for wireless communications. Certain aspects provide a method for wireless communication by a base station. The method generally includes determining a channel quality for a user equipment communicating on a wireless channel. The method further includes selecting one or more values for the one or more parameters for providing QoS to the user equipment in a range of parameter values based on the determined channel quality.

First claim

What is claimed is:

1 . A method for quality of service (QoS) configuration for wireless communications, the method comprising:
determining a channel quality for a user equipment communicating on a wireless channel; and selecting one or more values for one or more parameters for providing QoS to the user equipment in a range of parameter values based on the determined channel quality.

2 . The method of claim 1 , further comprising assigning the user equipment to a class of a plurality of classes, wherein each of the plurality of classes corresponds to a different range of parameter values for providing the QoS.

3 . The method of claim 2 , wherein the range of parameter values in which the one or more values for the one or more parameters for providing the QoS to the user equipment are selected corresponds to the assigned class.

4 . The method of claim 2 , further comprising providing, for each of the plurality of classes, a range for each of the one or more values for the one or more parameters for providing the QoS to the user equipment at each channel quality.

5 . The method of claim 2 , wherein the different range of parameter values partially overlap for a first class of the plurality of classes and a second class of the plurality of classes.

6 . The method of claim 1 , wherein the one or more parameters comprise one or more of packet delay budget, prioritized bit rate, guaranteed bit rate, or packet error loss rate.

7 . The method of claim 1 , wherein determining the channel quality comprises receiving a channel quality metric from the user equipment.

8 . The method of claim 1 , further comprising allocating resources on the wireless channel to the user equipment based on the selected one or more values for the one or more parameters for providing the QoS to the user equipment.

9 . The method of claim 8 , further comprising providing a range for each of the selected one or more values for the one or more parameters for providing the QoS to the user equipment at each channel quality, wherein allocating the resources comprises allocating the resources on the wireless channel to the user equipment further based on the range for each of the selected one or more values.

10 . The method of claim 1 , further comprising:
determining an updated channel quality for the user equipment; and selecting one or more updated values for the one or more parameters for providing the QoS to the user equipment in the range of parameter values based on the determined updated channel quality.

11 . The method of claim 1 , wherein determining the channel quality comprises:
determining a first channel quality for a first layer of the wireless channel; and determining a second channel quality for a second layer of the wireless channel, and wherein selecting one or more values for the one or more parameters for providing the QoS to the user equipment comprises:
selecting one or more values for the one or more parameters for providing the QoS to the user equipment on the first layer in the range of parameter values based on the determined first channel quality; and
selecting one or more values for the one or more parameters for providing the QoS to the user equipment on the second layer in the range of parameter values based on the determined second channel quality.

12 . The method of claim 11 , wherein the first layer comprises a first wireless carrier, and wherein the second layer comprises a second wireless carrier.

13 . The method of claim 11 , wherein the first layer comprises a first spatial layer, and wherein the second layer comprises a second spatial layer.

14 . An apparatus, comprising:
a memory; and a processor, the memory and the processor being configured to: determine a channel quality for a user equipment communicating on a wireless channel; and select one or more values for one or more parameters for providing quality of service (QoS) to the user equipment in a range of parameter values based on the determined channel quality.

15 . The apparatus of claim 14 , the memory and the processor being further configured to assign the user equipment to a class of a plurality of classes, wherein each of the plurality of classes corresponds to a different range of parameter values for providing the QoS.

16 . The apparatus of claim 15 , wherein the range of parameter values in which the one or more values for the one or more parameters for providing the QoS to the user equipment are selected corresponds to the assigned class.

17 . The apparatus of claim 15 , the memory and the processor being further configured to provide, for each of the plurality of classes, a range for each of the one or more values for the one or more parameters for providing the QoS to the user equipment at each channel quality.

18 . The apparatus of claim 15 , wherein the different range of parameter values partially overlap for a first class of the plurality of classes and a second class of the plurality of classes.

19 . The apparatus of claim 14 , wherein the one or more parameters comprise one or more of packet delay budget, prioritized bit rate, guaranteed bit rate, or packet error loss rate.

20 . The apparatus of claim 14 , wherein the memory and the processor being configured to determine the channel quality comprises the memory and the processor being configured to receive a channel quality metric from the user equipment.

21 . The apparatus of claim 14 , the memory and the processor being further configured to allocate resources on the wireless channel to the user equipment based on the selected one or more values for the one or more parameters for providing the QoS to the user equipment.

22 . The apparatus of claim 21 , the memory and the processor being further configured to provide a range for each of the selected one or more values for the one or more parameters for providing the QoS to the user equipment at each channel quality, wherein the memory and the processor being configured to allocate the resources comprises the memory and the processor being configured to allocate the resources on the wireless channel to the user equipment further based on the range for each of the selected one or more values.

23 . The apparatus of claim 14 , the memory and the processor being further configured to:
determine an updated channel quality for the user equipment; and select one or more updated values for the one or more parameters for providing the QoS to the user equipment in the range of parameter values based on the determined updated channel quality.

24 . The apparatus of claim 14 , wherein the memory and the processor being configured to determine the channel quality comprises the memory and the processor being configured to:
determine a first channel quality for a first layer of the wireless channel; and determine a second channel quality for a second layer of the wireless channel, and wherein the memory and the processor being configured to select one or more values for the one or more parameters for providing the QoS to the user equipment comprises the memory and the processor being configured to:
select one or more values for the one or more parameters for providing the QoS to the user equipment on the first layer in the range of parameter values based on the determined first channel quality; and
select one or more values for the one or more parameters for providing the QoS to the user equipment on the second laye
