Title:
DATA TRANSMISSION METHOD, DEVICE, AND COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/133860
Kind Code:
A1
Abstract:
Embodiments of the present application provide a data transmission method, a network device, and a terminal device. The method comprises: a network device sends first configuration information to a terminal device, the first configuration information comprising first carrier configuration information and first time configuration information, the first carrier configuration information indicating at least one carrier configured by the network device for a bearer or logical channel for performing a hybrid automatic repeat request (HARQ), the first time configuration information indicating the number of first transmission time unit bundles corresponding to each of the at least one carrier; and the network device sends or receives data corresponding to the bearer or the logical channel according to the first carrier configuration information and/or the first time configuration information. By means of the data transmission method in an embodiment of the present application, the transmission effect of low delay and high reliability can be achieved, and the utilization rate of resources can be improved.
