Abstract:
1. A data transmission method for a network side equipment capable of being communicably coupled to a terminal, the method comprising: receiving, by the network side equipment, a first downlink data packet sent for the terminal and preparing a second downlink data packet without a high layer protocol stack header by removing the high layer protocol stack header in the first downlink data packet and maintaining context information related to the removed high layer protocol stack header to recover the removed high layer protocol stack header when receiving an uplink data packet without a high layer protocol stack header from the terminal, wherein before sending the second downlink data packet to the terminal through an air interface connection, the network side equipment performing processes of: wherein the terminal processes the second downlink data packet without the high layer protocol stack header that is sent to the terminal through the air interface connection by:
