Application: Method for nr radio link monitoring (RLM) and evaluation period determination (Patent ID: US20230416132A1)
The patent filed by MediaTek Inc. proposes methods for defining user equipment (UE) behavior in performing synchronization signal block (SSB) based radio link monitoring (RLM) and channel state information reference signal (CSI-RS) based RLM. The first aspect involves the UE determining errors in CSI-RS RLM configuration if not QCLed to any CORESET. The second aspect configures SSB and RLM CSI-RS resources with different numerologies, allowing the UE to perform RLM based on TDMed configurations by the network. The third aspect involves determining an SMTC period and evaluating whether SMTC and RLM-RS are overlapped to determine the RLM evaluation period.
The claims of the patent detail a method where the UE receives SSB and CSI-RS configurations for RLM from the network, along with SMTC configurations, to determine the RLM evaluation period based on the shortest SMTC periodicity. The method includes considerations for SMTC periodicity, window duration, and timing offset, with the RLM evaluation period determined by the shortest SMTC periodicity. The UE is equipped with an RLM configuration circuit, receiver, and RLM control and handling circuit to implement the method, ensuring efficient RLM evaluation based on SMTC configurations and overlapping CSI-RS resources. The patent aims to enhance the synchronization and monitoring capabilities of UEs in wireless communication systems.
