Failure Handling for Secondary Cell - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240022929 titled 'Failure Handling for Secondary Cell

Simplified Explanation

The patent application describes a method for a user equipment (UE) connected to a wireless network in a carrier aggregation (CA) state with primary and secondary cell connections to recover from beam failures.

• The UE detects a beam failure in either the primary or secondary connection and initiates a beam failure recovery (BFR) operation.
• The BFR operation involves transmitting a BFR medium access control (MAC) control element to the primary cell.

Potential Applications

This technology could be applied in:

• 5G networks
• Mobile communication systems

Problems Solved

This technology addresses issues such as:

• Beam failures in wireless networks
• Maintaining seamless connectivity in CA states

Benefits

The benefits of this technology include:

• Improved reliability of wireless connections
• Enhanced user experience with reduced interruptions

Potential Commercial Applications

Potential commercial applications of this technology could be seen in:

• Telecommunications companies
• Network equipment manufacturers

Possible Prior Art

One possible prior art for this technology could be:

• Existing methods for beam failure recovery in wireless networks

Unanswered Questions

How does this technology impact battery life of the user equipment?

The patent application does not provide information on the potential impact of this technology on the battery life of the user equipment.

Are there any limitations to the range of beam failure recovery in this technology?

The patent application does not specify any limitations to the range of beam failure recovery in this technology.

Original Abstract Submitted

a user equipment (ue) is connected to a wireless network and operates in a carrier aggregation (ca) state that includes a first connection to a primary cell and a second connection to a secondary cell. the ue determines a beam failure has occurred for one of the first connection or the second connection and initiates a beam failure recovery (bfr) operation. the bfr operation includes transmitting, to the primary cell, a bfr medium access control (mac) control element (ce).
