SYSTEMS, METHODS, AND DEVICES FOR HARQ MANAGEMENT IN NON-TERRESTRIAL NETWORKS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240187145 titled 'SYSTEMS, METHODS, AND DEVICES FOR HARQ MANAGEMENT IN NON-TERRESTRIAL NETWORKS

Simplified Explanation

The techniques described in this patent application focus on managing hybrid automatic repeat request (HARQ) processes and communications for non-terrestrial networks (NTNs), such as satellite networks in wireless communication systems.

• User equipment (UE) can connect to an NTN and determine HARQ capabilities related to NTNs.
• The UE can send a HARQ disablement message to the NTN and communicate without HARQ procedures.
• The HARQ disablement message includes UE's disablement capabilities and may request the network to disable HARQ.
• The message may contain a radio resource control (RRC) reconfiguration message and address HARQ disablement per logical channel identifier (LCID) or dedicated radio bearer (DRB).

Potential Applications

This technology can be applied in satellite communication systems, IoT networks, and other wireless communication systems where HARQ processes need to be managed efficiently.

Problems Solved

1. Efficient management of HARQ processes in non-terrestrial networks. 2. Seamless communication between user equipment and NTN without HARQ procedures.

Benefits

1. Improved reliability and performance in NTN communications. 2. Enhanced flexibility in managing HARQ processes based on UE capabilities. 3. Reduced latency and improved overall network efficiency.

Potential Commercial Applications

The technology can be utilized in satellite communication systems, IoT devices, remote sensing applications, and other wireless communication systems requiring reliable and efficient data transmission.

Possible Prior Art

One possible prior art could be the use of HARQ processes in traditional terrestrial wireless communication systems. However, the specific application of managing HARQ processes in non-terrestrial networks may be a novel aspect of this technology.

Unanswered Questions

How does this technology impact the overall network latency in NTN communications?

The patent application does not provide specific details on the impact of this technology on network latency in NTN communications.

What are the potential challenges in implementing HARQ disablement in NTN communications?

The patent application does not address any potential challenges that may arise in implementing HARQ disablement in NTN communications.

Original Abstract Submitted

techniques, described herein, include solutions for managing hybrid automatic repeat request (harq) processes and communications for non-terrestrial networks (ntns) (e.g., a wireless communication network that includes a satellite network component). a user equipment (ue) may connect to an ntn and determine hybrid automatic repeat request (harq) capabilities regarding ntns. the ue may also communicate a harq disablement message to the ntn and communicate with ntn without harq procedures. the harq disablement message may provide the harq disablement capabilities of the ue and/or be a request for the network to disable harq. the harq disablement message may include a radio resource control (rrc) reconfiguration message and may address harq disablement per logical channel identifier (lcid) or dedicated radio bearer (drb).
