A ROBUST RADIO LINK MONITORING METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240187899 titled 'A ROBUST RADIO LINK MONITORING METHOD

Simplified Explanation

The patent application describes a method to improve Radio Link Monitoring (RLM) by allowing a User Equipment (UE) to apply a longer monitoring window for out-of-sync determinations before triggering an RLM timer for in-sync determinations. The UE first obtains a reference signal from a base station, then determines multiple groups of consecutive out-of-sync indications in response to the reference signal. After identifying these groups, the UE triggers the RLM timer. This approach enables the UE to perform additional out-of-sync monitoring during RLM, accounting for rapid Block Error Rate (BLER) changes that may occur in Heterogeneous Networks (HetNets) due to tropospheric turbulence.

• The UE obtains a reference signal from a base station.
• The UE determines multiple groups of consecutive out-of-sync indications in response to the reference signal.
• The UE triggers the RLM timer after identifying these groups.

Potential Applications

This technology could be applied in wireless communication systems to enhance the accuracy of RLM determinations and minimize Radio Link Failure (RLF) detections.

Problems Solved

1. Rapid BLER changes in HetNets due to tropospheric turbulence. 2. Inaccurate RLM determinations leading to frequent RLF detections.

Benefits

1. Improved accuracy in RLM determinations. 2. Reduced RLF detections. 3. Enhanced performance in wireless communication systems.

Potential Commercial Applications

This technology could be beneficial for telecommunications companies, network equipment manufacturers, and providers of wireless communication services.

Possible Prior Art

One possible prior art could be the use of looped out-of-sync monitoring in wireless communication systems to improve RLM accuracy.

How does this technology impact battery life in UEs?

The patent application does not address the potential impact of this technology on the battery life of User Equipment. It would be essential to understand if the longer monitoring window affects power consumption.

What are the potential challenges in implementing this technology in existing wireless networks?

The patent application does not discuss the challenges that may arise when integrating this technology into current wireless communication systems. It would be crucial to consider compatibility issues and the need for software or hardware upgrades.

Original Abstract Submitted

aspects are provided which improve rlm by allowing a ue to apply a longer monitoring window for out-of-sync determinations before the ue triggers an rlm timer for in-sync determinations. the ue first obtains a reference signal from a base station. the ue then determines multiple groups of consecutive out-of-sync indications in response to the reference signal. for example, the ue may perform looped out-of-sync monitoring, multi-cell or carrier monitoring, or a combination of such monitoring to determine the multiple groups of out-of-sync indications. afterwards, the ue triggers the rlm timer in response to determining the multiple groups of consecutive out-of-sync indications. as a result, the ue may perform additional out-of-sync monitoring during rlm before proceeding with in-sync monitoring, thus allowing the ue to account for rapid bler changes (ping-pong effects) that may occur in haps systems due to tropospheric turbulence and enabling more accurate rlm determinations and minimal rlf detections.
