Method for measuring carriers in rrc inactive mode
A recently granted patent (Publication Number: US12003985B2) discloses an apparatus and method for efficient communication in a wireless network. The apparatus includes a processor and memory with a computer program code that enables the device to acquire a configuration for secondary cells from the network, enter a radio resource control (RRC) inactive mode, maintain part of the configuration during the inactive mode, determine which carriers to measure during the inactive mode based on the configuration, perform measurements, and provide results to the network upon entering an RRC connected mode. The system focuses on measuring only a subset of carriers, specifically those activated within a predetermined duration before entering the inactive mode.
Furthermore, the apparatus is designed to receive a state transition message from the network, acquire information on the validity duration for determining which carriers to measure during the inactive mode, and apply multicarrier connectivity for communication with the network after entering the RRC connected mode. The validity duration is specified separately for each carrier to be measured, allowing for flexibility in managing different carriers with varying validity durations. This innovative approach aims to enhance network efficiency and optimize communication processes, particularly in New Radio (NR) communication networks where the apparatus functions as user equipment.
