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:
receiving, by a base station, uplink data identifying uplink performance indicators associated with user equipment connected to the base station;
receiving, by the base station, tuning factors associated with shared channel traffic received by the user equipment and receiving quality of service requirements of the user equipment;
determining, by the base station, 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;
determining, by the base station, whether the total score satisfies a threshold score;
switching, by the base station, to the long duration PUCCH format for the uplink control information based on the total score satisfying the threshold score; and
performing, by the base station, one or more actions based on switching to the long duration PUCCH format for the uplink control information.

2. The method of claim 1 , further comprising:
maintaining a short duration PUCCH format for the uplink control information based on the total score failing to satisfy the threshold score.

3. The method of claim 1 , wherein the uplink performance indicators include 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.

4. The method of claim 1 , 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.

5. The method of claim 1 , wherein the long duration PUCCH format includes one of:
a first format that includes one bit of the uplink control information and one physical resource block,
a second format that includes more than two bits of the uplink control information and a plurality of physical resource blocks, or
a third format that includes more than two bits of the uplink control information and one physical resource block.

6. The method of claim 1 , wherein determining the total score comprises:
assigning scores to the uplink performance indicators and the tuning factors to generate a plurality of scores; and
determining the total score based on the plurality of scores.

7. The method of claim 1 , wherein determining the total score associated with utilizing the long duration PUCCH format for the uplink control information includes:
processing the uplink data and the tuning factors, with a machine learning model, to determine the total score associated with utilizing the long duration PUCCH format for the uplink control information,
wherein the machine learning model includes a decision tree machine learning model.

8. A base station, comprising:
