MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202647121391 A) filed by Qualcomm Incorporated on October 09, 2026, for Techniques Associated With Contention Window Size Selection In Wi-Fi Systems.
Inventors include Katar, Srinivas; Wentink, Maarten Menzo; Cherian, George; Lee, Jinsung; Kakani, Naveen Kumar; Banerjea, Raja; Asterjadhi, Alfred; and Huang, Xiaolong.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: This disclosure provides methods, components, devices and systems for techniques associated with contention window size selection in Wi-Fi systems. Some implementations relate to mechanisms according to which a wireless communication device may select a contention window size for a transmission attempt to maintain relatively smaller contention window sizes in some scenarios and to use relatively larger contention window sizes in some other scenarios. In some examples, a wireless communication device may statically use a same contention window size for a given access category. Additionally, or alternatively, the wireless communication device may use a first contention window size for a first quantity of transmission attempts and a second contention window size for a second quantity of transmission attempts. Additionally, or alternatively, the wireless communication device may use a selection scheme according to which the wireless communication device directly maps a collision probability to a contention window size.
