Problems solved by technology
However, if the available physical resources in the current slot are less than the actual required physical resources, the bit rate of the rate matching output will increase, thereby deteriorating the transmission quality, which is reliable for transmission such as URLLC services and eURLLC services. For services with high requirements, it is difficult to meet the high reliability service quality requirements of the business, which seriously affects the service quality

The invention relates to a data transmission method and a device thereof. The data transmission method comprises the steps of when the time frequency resource required by a target transmission block in emergent transmission is larger than the available time frequency resource of a target time slot, performing rate matching on codes which correspond with the target transmission block, and obtaininga target code; wherein, the number of bits of the target code is not higher than the number of bits of an available physical load of the target time slot; respectively transmitting the target code bymeans of a first set of antenna assembly at the available time domain resource of the target time slot and the available time domain resource of a pre-configured second set of antenna assembly at thetarget time slot; wherein the first set of antenna assembly and the second set of antenna assembly have same hardware configuration information and resource configuration information. The data transmission method and the device thereof can obtain a transmitting diversity gain and ensures high reliability of the service in a scene when the actual required time frequency resource of emergent transmission is higher than the available time frequency resource of the target time slot, thereby improving transmission quality.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method and device. Background technique [0002] Because different service types have different service quality requirements for wireless communication technologies, for example, the main requirements of enhanced Mobile Broadband (eMBB, enhanced Mobile Broad Band) service types focus on large bandwidth and high speed, and high reliability and low delay communication (URLLC , Ultra Reliable Low Latency Communication) business type mainly requires high reliability and low delay, and massive machine type communication (mMTC, massive machine type of communication) business type mainly requires a large number of connections , therefore, the new generation of wireless communication system needs to support the transmission of various business types through a flexible and configurable design. [0003] In the related art, in the mapping type B (mapping ...
