Abstract

The embodiment of the invention discloses a data processing method and a data processing device. The data processing method provided by the embodiment of the invention comprises the following steps of: receiving a data unit; and when a serial number of the received data unit is greater than the upper limit of a sliding window and an interval between the serial number of the data unit and the upper limit of the sliding window is smaller than a preset value, receiving the data unit, wherein the preset value is smaller than the size of the sliding window. The method and the device have the advantages of narrowing the range of movement of the upper limit of the sliding window and reducing the probability of receiving repetitive data units to further reduce the power consumption of a system and improve the performance of the system.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a data processing method and device. Background technique [0002] The LTE (Long Term Evaluation, long-term evolution) project is an evolution of 3G, which is proposed by integrating a part of 4G core technologies. LTE improves and enhances the air access technology of 3G, and adopts OFDM (Orthogonal Frequency Division Multiplexing) and MIMO (Multiple Input Multiple Output) as standards for its wireless network evolution. [0003] The RLC (Radio Link Control, radio link control) layer is located in the L2 (Layer 2, layer 2) part of the LTE system frame. Automatic repeat request) and other functions. The RLC transmission mode is divided into TM (Transparent Mode, transparent mode), UM (Unacknowledged Mode, unacknowledged mode) and AM (Acknowledged Mode, acknowledged mode). [0004] During data transmission using UM, different PDUs (Protocol Data Unit, proto...
