摘要： Embodiments of the present disclosure relate to methods and devices for data retransmission. In example embodiments, a method implemented in a first device is provided. According to the method, a RLC packet to a second device is transmitted on a RLC layer. It is determined whether an ACK feedback for the RLC packet is received from the second device during a predetermined RLC retransmission period. In response to missing the ACK feedback during the RLC retransmission period, the RLC packet is retransmitted to the second device on the RLC layer, regardless whether a NACK feedback for the previously transmitted RLC packet is received from the second device.
