Title:
DATA TRANSMISSION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/132873
Kind Code:
A1
Abstract:
The invention relates to a data transmission method and device. The method comprises the following steps: when the time-frequency resource required by a target transmission block in burst transmission is greater than the available time-domain resource of a target time slot, performing rate matching on code words corresponding to the target transmission block, the bit number of the target code words being not greater than that of the available physical carriers of the target time slot; respectively using the available time domain resources of a first antenna assembly in the target time slot and the available time domain resources of a second pre-configured antenna assembly in the target time slot to transmit target code words, the first antenna assembly and the second antenna assembly having the same hardware configuration information and resource allocation information. According to the technical solution, transmit diversity gain can be obtained to ensure the reliability of services in a scenario where the time-frequency resources actually required for burst transmission are greater than the available time-domain resources of the target time slot, thereby improving the transmission quality.
