DATA TRANSMISSION METHOD AND RECEIVING METHOD, AND TRANSMISSION DEVICE AND RECEIVING DEVICE

摘要

Provided are a data transmission method and receiving method, and transmission device and receiving device. The transmission method comprises: obtaining a first number of parallel channel resources configured to transmit data to a single target receiving station; processing the data as a second number of physical layer service data units, wherein the second number is two or more; and transmitting, on the first number of the parallel channel resources, a radio frame comprising the second number of the physical layer service data units. The present invention addresses a problem existing in the related art of a low data transmission efficiency with respect to a single user, thereby increasing the data transmission efficiency with respect to a single user.
