Title
(EN) DATA TRANSMISSION METHOD WIRELESS NETWORK NODE AND COMMUNICATION SYSTEM
Abstract
(EN)
Disclosed in an embodiment of the present invention is a data transmission method comprising: a first wireless network node obtaining a bearer type of a downlink data packet; and if the bearer type is Signaling Radio Bearer (SRB) the first wireless network node transmitting the downlink data packet to a second wireless network node so that the second wireless network node performs a function of a Packet Data Convergence Protocol (PDCP) layer to the downlink data packet; or if the bearer type is Data Radio Bearer (DRB) the first wireless network node performing the function of the PDCP layer to the downlink data packet and transmitting the processed downlink data packet to the second wireless network node. Correspondingly also disclosed in the embodiment of the present invention is a wireless network node capable of reducing the requirements of the transmission bandwidth and the time delay.
