Abstract

The invention discloses a data sending method, a data receiving method, equipment and a system, belonging to the technical field of communication. The data sending method includes: precoding multiple spatial streams to obtain multiple precoded data streams, the multiple spatial streams include at least two first pre-processed spatial streams, and the at least two first pre-processed spatial streams are for the first pre-processed spatial stream Obtained by preprocessing an original spatial stream; transmitting multiple precoded data streams. The invention solves the problem of low scheduling flexibility and achieves the effect of improving scheduling flexibility. The invention is used for data transmission.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data sending method, a data receiving method, equipment and a system. Background technique [0002] The long-term evolution (English: Long Term Evolution; abbreviation: LTE) or advanced long-term evolution (English: Longterm evolution-advanced; abbreviation: LTE-A) system adopts multiple input multiple output (English: Multiple Input Multiple Output; abbreviation: MIMO) technology, The MIMO technology improves the performance of the LTE or LTE-A system by deploying multiple antennas on the transmitting end device and the receiving end device. For example, the transmitting end device may be a base station, the receiving end device may be user equipment (English: User equipment; UE for short), and the base station may schedule multiple UEs to perform data transmission. [0003] In related technologies, multiple UEs scheduled at the same time must use the same tran...
