The patent application focuses on enhancing radio link monitoring and beam failure detection in wireless communication systems. It outlines methods, systems, and devices aimed at improving the reliability and efficiency of these operations. This is particularly relevant for scenarios where handover procedures in the network might fail, leading to radio link failures. The application builds on existing techniques from the Third Generation Partnership Project (3GPP) networks, which describe methods for detecting and recovering from beam failures.
In current 3GPP networks, radio link monitoring is crucial for maintaining connection stability. When a handover is unsuccessful or not performed, radio link failures can occur. Beam failure recovery is another critical aspect, involving the detection of beam failures, selection of new beams, and restoration of connections. The application aims to address these challenges by refining existing techniques and introducing new methods for managing transitions in reference signal configurations.
The application provides a detailed description of various embodiments and techniques, supported by accompanying drawings. It emphasizes the importance of specific structures, architectures, interfaces, and methods to ensure a comprehensive understanding of the embodiments. The description also highlights the use of specific terminology such as "circuitry," "processor circuitry," and "interface circuitry," defining their roles in executing the described functionalities.
The described system includes a user equipment (UE) and an access node, such as a base station, which provides wireless serving cells. The access node transmits information in the downlink direction, mapping logical channels onto transport and physical channels. These channels facilitate data transfer across different layers, ensuring effective communication between the UE and the access node. The physical channels include the physical broadcast channel (PBCH), which broadcasts system information vital for the UE's initial access to a serving cell.
The PBCH, along with physical synchronization signals, forms part of the synchronization signal (SS)/PBCH block, used by the UE during cell search procedures and beam selection. This setup is designed to enhance the UE's ability to maintain robust communication links by efficiently managing the transition of reference signal configurations, thereby improving the timing of evaluation periods for radio link monitoring and beam failure detection.
