Title:
DATA SENDING AND RECEIVING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/028331
Kind Code:
A1
Abstract:
Provided are a data sending and receiving method and device. The method comprises: a sending end device performing pre-encoding on a plurality of spatial streams; obtaining a plurality of pre-encoded data streams; and transmitting the plurality of pre-encoded data streams, wherein at least two spatial streams in the plurality of spatial streams are obtained by performing emitting diversity processing on an original spatial stream. Since some spatial streams in a plurality of spatial streams on the same time-frequency resource may be transmitted by using a beam forming transmission mode based on emitting diversity, and the other spatial streams may be transmitted by using a space division multiplexing mode, the usage rate of a time-frequency resource is thereby improved.
