Abstract

A base station may receive uplink data identifying uplink performance indicators associated with user equipment connected to the base station, and may receive tuning factors associated with shared channel traffic received by the user equipment and quality of service requirements of the user equipment. The base station may determine a total score associated with utilizing a long duration physical uplink control channel (PUCCH) format for uplink control information based on the uplink data and the tuning factors. The base station may determine that the total score satisfies a threshold score and may switch to the long duration PUCCH format for the uplink control information based on the total score satisfying the threshold score. The base station may perform one or more actions based on switching to the long duration PUCCH format for the uplink control information.

First claim

What is claimed is:

1. A method, comprising:
determining, by a base station, a total score associated with utilizing a long duration physical uplink control channel (PUCCH) format for uplink control information based on uplink data associated with user equipment connected to the base station,
wherein the total score comprises:
assigning weights to a plurality of scores associated with the uplink data, and
determining the total score based on the plurality of scores;

determining, by the base station, a PUCCH format based on whether the total score satisfies a threshold score; and
performing, by the base station, one or more actions based on the PUCCH format.

2. The method of claim 1 , wherein determining the total score comprises:
determining the total score associated with utilizing the long duration PUCCH format for the uplink control information based on tuning factors associated with shared channel traffic.

3. The method of claim 1 , wherein performing the one or more actions comprises:
maintaining a short duration PUCCH format for the uplink control information when the total score fails to satisfy the threshold score.

4. The method of claim 1 , wherein performing the one or more actions comprises:
switching to the long duration PUCCH format for the uplink control information when the total score satisfies the threshold score.

5. The method of claim 1 , wherein determining the total score comprises:
determining the total score associated with utilizing the long duration PUCCH format for the uplink control information based on one or more quality of service requirements for the user equipment.

6. The method of claim 1 , wherein
the plurality of scores are based on uplink performance indicators, and wherein the uplink data identifies the uplink performance indicators.

7. The method of claim 1 , wherein the uplink data includes one or more of:
error rates associated with the user equipment,
a quantity of the user equipment associated with errors, or
a quantity of the user equipment with high mobility rates.

8. A base station, comprising:
one or more processors configured to:
determine a total score associated with utilizing a long duration physical uplink control channel (PUCCH) format for uplink control information based on one or more of:
uplink data associated with user equipment connected to the base station, and
tuning factors associated with the user equipment connected to the base station;
wherein the one or more processors, when determining the total score, are to:
assign weights to a plurality of scores associated with the uplink data, and
determine the total score based on the plurality of scores;

determine whether the total score satisfies a threshold score;
determine a PUCCH format based on whether the total score satisfies the threshold score; and
perform one or more actions based on the PUCCH format.

9. The base station of claim 8 , wherein the uplink data identifies uplink performance indicators associated with the user equipment connected to the base station.

10. The base station of claim 8 , wherein, the one or more processors, to determine the total score, are configured to:
assign scores to uplink performance indicators associated with the uplink data and the tuning factors to generate the plurality of scores;
apply weights to the plurality of scores to generate a plurality of weighted scores; and
combine the plurality of weighted scores to determine the total score.

11. The base station of claim 8 , wherein the one or more processors, to perform the one or more actions, are configured to:
cause one or more of the user equipment to utilize the long duration PUCCH format when the total score satisfies the threshold score.

12. The base station of claim 8 , wherein the one or more processors, to perform the one or more actions, are configured to:
select the long duration PUCCH format from a plurality of long duration PUCCH formats when the total score satisfies the threshold score; and
cause one or more of the user equipment to utilize the selected long duration PUCCH format.

13. The base station of claim 8 , wherein the one or more processors, to perform the one or more actions, are configured to:
maintain a short duration PUCCH format for the uplink control information based on the total score failing to satisfy the threshold score.

14. The base station of claim 8 , wherein the tuning factors are further associated with one or more of:
distances between the user equipment and the base station,
radio frequency conditions of the user equipment,
service types of the user equipment, or
applications utilized by the user equipment.

15. A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:
one or more instructions that, when executed by one or more processors of a base station, cause the base station to:
determine a total score associated with utilizing a long duration physical uplink control channel (PUCCH) format for uplink control information based on uplink data associated with user equipment connected to the base station,
wherein the one or more instructions, that cause the base station to determine the total score, cause the base station to:
assign weights to a plurality of scores associated with the uplink data, and
determine the total score based on the plurality of scores;

determine a PUCCH format based on whether the total score satisfies a threshold score; and
perform one or more actions based on the PUCCH format.

16. The non-transitory computer-readable medium of claim 15 , wherein the one or more instructions, that cause the base station to perform the one or more actions, cause the base station to:
maintain a short duration PUCCH format for the uplink control information based on the total score failing to satisfy the threshold score.

17. The non-transitory computer-readable medium of claim 15 , wherein the one or more instructions, that cause the base station to perform the one or more actions, cause the base station to:
switch to a long duration PUCCH format for the uplink control information when the total score satisfies the threshold score.

18. The non-transitory computer-readable medium of claim 15 , wherein the one or more instructions, that cause the base station to determine the total score, cause the base station to:
receive tuning factors associated with shared channel traffic received by the user equipment and quality of service requirements of the user equipment;
