RADIO CHANNEL FAILURE (RLF) HANDLING METHOD AND TERMINAL DEVICE Russian patent published in 2021 - IPC H04L1/00 

FIELD: wireless communication.

SUBSTANCE: invention relates to wireless communication and can be used in terminal devices in the event of a radio link failure (RLF), which occurs when a transmission channel with replication function is in an active state. The radio link failure (RLF) method includes disabling the terminal device of the replication and data transmission function of the first transmission channel and/or disabling the terminal device of the replication and data transmission function of the second transmission channel, if the retransmission of data of the first transmission channel on the first radio channel control (RLC) entity corresponding to the first transmission channel reaches the maximum number of retransmissions, the carrier frequency displayed by the RLC entity corresponding to the second transmission channel at least partially overlaps the carrier frequency displayed the first RLC object.

EFFECT: invention improves reliability of data transmission.
