Title:
COMMUNICATION METHOD AND COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/068202
Kind Code:
A1
Abstract:
The present application provides a signal transmission method and apparatus, which can achieve, without reconfiguring a transmission mode (TM) for a terminal device, the following functions: supporting the scheduling of single-user multi-stream spatial multiplexing, and the maximum number of layers of supported MUBF pairings being greater than 8. The method comprises: a terminal device receives a first demodulation reference signal (DMRS) in a first TM, the first DMRS supporting single-user multi-stream spatial multiplexing; the terminal device receives first indication information from a network device, and according to the first indication information, receives a second DMRS in the first TM, wherein the maximum number of layers of MUBF pairings supported by the second DMRS is greater than 8.
