Methods and apparatuses for a user equipment, UE, to report radio link failure, RLF, in a wireless network, said methods include sending, to a radio network node, RNN, in the wireless network, a first message including: a first RLF report related to an RLF that occurred in a cell of the wireless network, and a second indication of availability of one or more further RLF reports stored by the UE. The methods further include receiving, from the RNN, a second request for at least a portion of the stored RLF reports indicated by the second indication and sending, to the RNN, a second response including a second RLF report of the stored RLF reports. The apparatuses are configured to perform such methods.

Embodiments herein relate to a method implemented by a wireless communication device. The wireless communication device transmits data to a radio node of a wireless communication network. The wireless communication device monitors for a positive acknowledgement or a negative acknowledgement of the data from the radio node. The wireless communication device retransmits the data to the radio node when said monitoring indicates reception of a negative acknowledgement of the data. The wireless communication device refrains from retransmitting the data to the radio node when said monitoring indicates reception of a positive acknowledgement of the data. The wireless communication device also refrains from retransmitting the data to the radio node when said monitoring indicates neither reception of a positive acknowledgement of the data nor reception of a negative acknowledgement of the data.
