Abstract

Embodiments of the present application provide a data processing method and device, which can avoid unnecessary cache overhead as much as possible. The method includes: starting a timer for limiting the buffering duration for the first packet data convergence protocol PDCP service data unit SDU; when the timer expires, controlling the first media access including the first PDCP SDU MAC data unit for processing.

Description

technical field [0001] The present application relates to the communication field, and more specifically, to a data processing method and device. Background technique [0002] In the Long Term Evolution (LTE) system, when the sender sends data, it will set the maximum number of retransmissions for the Media Access Control (MAC) data unit. If the transmission fails all the time and reaches the maximum When the number of retransmissions is increased, the media access control (Media Access Control, MAC) data unit stored in the buffer may be cleared. [0003] Only when the maximum number of retransmissions is reached, the data in the cache is cleared, which will cause unnecessary cache overhead. Contents of the invention [0004] Embodiments of the present application provide a data processing method and device, which can avoid unnecessary cache overhead as much as possible. [0005] In the first aspect, a data processing method is provided, including: [0006] Start a time...
