Abstract
A method for a communications system, wherein in response to detecting a radio link problem during a first phase of a radio link failure, the first user terminal transmits an indication of the detection of the radio link problem to a second user terminal over a device-to-device link. In response to a report on the radio link problem detection of the first user terminal being sent from the second user terminal to a network apparatus, the first user terminal receives a confirmation on a status of the report from the second user terminal over the device-to-device link. Based on the confirmation, the first user terminal decides, whether to stop a first radio link failure timer, reset the first radio link failure timer, or extend the first radio link failure timer.
