SYSTEM AND METHOD FOR SUPPORTING MULTICAST BROADCAST SERVICE (MBS) SERVICE IN NON-TERRESTRIAL NETWORK (NTN) - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240204925 titled 'SYSTEM AND METHOD FOR SUPPORTING MULTICAST BROADCAST SERVICE (MBS) SERVICE IN NON-TERRESTRIAL NETWORK (NTN)

The patent application describes a system and method for supporting Multicast Broadcast Service (MBS) in a Non-Terrestrial Network (NTN). A User Equipment (UE) device is equipped with at least one antenna, at least one radio for wireless communication using various radio access technologies, and one or more processors. The radio and processors are configured to receive MBS data and determine transmission timing for Hybrid Automatic Repeat Request (HARQ) feedback transmissions based on timing offsets provided by a network device.

• User Equipment (UE) device includes antenna, radio, and processors for receiving MBS data and determining transmission timing for HARQ feedback transmissions.
• HARQ feedback transmission timing is based on timing offsets provided by a network device.
• Supports Multicast Broadcast Service (MBS) in a Non-Terrestrial Network (NTN).
• Enables efficient communication and feedback transmission in non-terrestrial network environments.

Potential Applications: This technology can be applied in satellite communication systems, space-based networks, and other non-terrestrial communication platforms requiring multicast broadcast services.

Problems Solved: Addresses the challenge of efficient multicast broadcast service support in non-terrestrial networks. Improves communication reliability and feedback transmission timing in NTN environments.

Benefits: Enhanced performance and reliability of multicast broadcast services in non-terrestrial networks. Optimized transmission timing for feedback in NTN communication systems.

Commercial Applications: Title: "Non-Terrestrial Network Communication System for Multicast Broadcast Services" Commercial uses include satellite communication systems, space-based networks, and other non-terrestrial communication platforms. Market implications include improved efficiency and reliability of multicast broadcast services in NTN environments.

Prior Art: Readers can explore prior patents related to multicast broadcast services in non-terrestrial networks, HARQ feedback transmissions, and communication systems in NTN environments.

Frequently Updated Research: Stay informed about advancements in satellite communication technologies, space-based networks, and non-terrestrial communication systems for potential updates related to this technology.

Questions about the technology: 1. How does this technology improve multicast broadcast services in non-terrestrial networks? 2. What are the key advantages of using timing offsets for HARQ feedback transmissions in NTN communication systems?

Original Abstract Submitted

the disclosure relates to system and method for supporting multicast broadcast service (mbs) service in non-terrestrial network (ntn). in some aspects, a user equipment (ue) device may comprises: at least one antenna; at least one radio, configured to perform wireless communication using at least one radio access technology; and one or more processor coupled to the at least one radio, wherein the at least one radio and the one or more processor are configured to receive multicast broadcast service (mbs) data, wherein the one or more processor are configured to case the ue device to: receive, from a network device, a timing offset indicating a slot offset for a hybrid automatic repeat request (harq) feedback transmission; and determine a transmission timing for an harq feedback transmission for the mbs data based on the timing offset.
