Title: METHOD AND APPARATUS FOR DATA RETRANSMISSION, AND MAC DEVICE
Abstract:
Provided in the present invention are a method and apparatus for data retransmission, and a media access control (MAC) device. The data retransmission method comprises: if the retransmission of a media access control service data unit (MAC SDU) fails, detecting whether the failure waiting time of the MAC SDU has timed out; if the judgment result is no, retransmitting the MAC SDU and/or relevant data of the MAC SDU. The present invention solves the problems in the related art that a two-layer retransmission mechanism may delay the timely submission of service data to an application layer, and affect the quality of service (QoS) of the service, thereby achieving the effect of expediting the submission of the data to the application layer and improving the QoS of the service.
