Title:
DATA TRANSMISSION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/124487
Kind Code:
A1
Abstract:
The present invention relates to a data transmission method and device. The method comprises: sending a target warning sequence to a network access device using a first uplink grant-free transmission resource corresponding to the target warning sequence, wherein the target warning sequence is used to inform the network access device terminal to request to use the first uplink grant-free transmission resource to send data; upon receiving a collision indication fed back by the network access device in response to the target warning sequence, sending uplink data using a transmission resource which is different from the first uplink grant-free transmission resource. In the present technical solution, before sending the uplink data by means of the terminal, the first uplink grant-free transmission resource corresponding to the target warning sequence is used to send the warning sequence to the network access device, which may avoid the problem of conflict during multi-user resource multiplexing transmission, reduce the transmission interference, improve the demodulation performance and ensure service quality.
