Title: DATA TRANSMITTING METHOD, DATA RECEIVING METHOD, NETWORK DEVICE, AND TERMINAL DEVICE
Abstract:
Provided are a data transmitting method, a data receiving method, a network device, and a terminal device capable of obtaining a higher diversity gain, increasing quality of a received signal, and increasing reliability of data transmission. The method comprises: a network device performing transmit diversity preprocessing on a modulation symbol stream to obtain one or more transmit diversity spatial streams; the network device performing precoder cycling on the one or more transmit diversity spatial streams to obtain one or more pre-coded data streams, wherein each of the one or more transmit diversity spatial streams corresponds to at least two different pre-coded vectors; and the network device transmitting, to a first terminal device, the one or more pre-coded data streams.
