Abstract
A method of a trigger mechanism of buffer status report (BSR) and scheduling request (SR) for a media access control layer of a user equipment in a wireless communication system, the method including receiving a first data, identifying a state of semi-persistent scheduling (SPS) resource configuration and a type of the first data when the first data arrives at a transmission buffer and deciding a state of a BSR-SR triggering according to the state of SPS resource configuration, the type of the first data and a comparison between a size of a second data in the transmission buffer and a threshold.
