==LBT Parameters for SRS Transmission - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18450565 titled 'LBT Parameters for SRS Transmission

==Simplified Explanation==

The patent application describes a method for managing the size of a contention window in a user equipment (UE) for unlicensed spectrum transmissions. The method involves performing a listen-before-talk (LBT) procedure using a specific contention window size and priority class for an acknowledged uplink transmission. It also includes transmitting an un-acknowledged uplink transmission and receiving an acknowledgement for the first transmission. Based on the received acknowledgement, both the contention window size for the acknowledged transmission and a second contention window size are modified. A second LBT procedure is then performed using the modified contention window size and a different priority class for an un-acknowledged uplink transmission.

* The method involves managing the contention window size in a UE for unlicensed spectrum transmissions.
* It includes performing a first LBT procedure for an acknowledged uplink transmission.
* The method also involves transmitting an un-acknowledged uplink transmission and receiving an acknowledgement for the first transmission.
* Based on the received acknowledgement, both the contention window size for the acknowledged transmission and a second contention window size are modified.
* A second LBT procedure is performed using the modified contention window size and a different priority class for an un-acknowledged uplink transmission.

== Potential Applications ==
* This method can be applied in various wireless communication systems that utilize unlicensed spectrum, such as Wi-Fi networks.
* It can be used in devices like smartphones, tablets, laptops, and IoT devices that rely on unlicensed spectrum for uplink transmissions.

== Problems Solved ==
* The method addresses the issue of contention in unlicensed spectrum by managing the contention window size.
* It helps in optimizing the transmission performance by adjusting the contention window size based on the acknowledgement received for previous transmissions.

== Benefits ==
* By dynamically modifying the contention window size based on acknowledgements, the method improves the efficiency and reliability of uplink transmissions in unlicensed spectrum.
* It allows for better management of contention and reduces the chances of collisions and interference in the spectrum.
* The method helps in maximizing the utilization of unlicensed spectrum resources and improving overall network performance.


==Original Abstract Submitted==

According to some embodiments, a method for use in a user equipment (UE) of managing a listen-before-talk (LBT) contention window size comprises performing a first LBT procedure using a first contention window size and priority class for a first uplink transmission in unlicensed spectrum. The first uplink transmission comprises an acknowledged transmission. The method further comprises transmitting a second uplink transmission. The second uplink transmission comprises an un-acknowledged transmission. The method further comprises receiving an acknowledgement for the first uplink transmission, and modifying both the first contention window size and a second contention window based on the received acknowledgement. The method further comprises performing a second LBT procedure using the second contention window size and a second priority class for a third uplink transmission in unlicensed spectrum. The third uplink transmission comprises an un-acknowledged transmission.
