Title:
DATA TRANSMISSION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/214119
Kind Code:
A1
Abstract:
Provided by the present application are a method and device for transmitting data. The method comprises: in a first time period, a first node receiving first data of a first node on a first resource allocated to the first node and receiving second data of a second node on a second resource allocated to the second node; the first node sending the second data on the second resource in a second time period according to a first rule, wherein the first rule comprises one or more of the following: if the first data is received successfully or decoded correctly, sending the second data; if first feedback information indicating that receiving of the second data failed is received, sending the second data; if the current time period is the second time period, sending the second data; and if an emergency degree of the second data meets an emergency condition, sending the second data. By means of the present application, the first node may transmit different data by means of the first frequency band and the second frequency band respectively, which may effectively reduce transmission delay and improve efficiency. The method provided in the present embodiment may be applied to communication systems, such as V2X, LTE-V, V2V, vehicle networking, MTC, IoT, LTE-M, M2M, Internet of Things, and the like.
