MUMBAI, India, March 14 -- Intellectual Property India has published a patent application (202431068059 A) filed by Indian Institute Of Technology, Kharagpur, West Bengal, on Sept. 9, 2024, for 'system and method for delay-reliability aware downlink-scheduling in 5g nr for extended reality (xr) services using delay tracking mechanism.'
Inventor(s) include Moyukh Laha; and Goutam Das.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "This invention discloses a novel downlink scheduling scheme to maximize the number of XR users who meet their strict delay reliability requirements in 5G networks. Each XR user is assigned a predefined delay bound, within which Data Units (DUs) - encompassing packets, frames, or Service Data Units (SDUs) - must be transmitted. Failure to transmit within this bound results in a delay violation, which can degrade the user's experience. Additionally, each user has a specified reliability threshold, denoted as X%, indicating the minimum percentage of DUs that must be successfully delivered within the delay bound to meet the user's quality expectations. The proposed scheduling scheme ensures that the highest possible number of XR users achieve their required delay reliability. To accomplish this, the scheme integrates two critical components: (a) a delay tracking mechanism, and (b) a downlink scheduling strategy that optimizes scheduling based on real-time delay information."
