DATA SENDING METHOD AND APPARATUS

WIPO Patent Application WO/2024/067244

A1

The present application provides a data sending method and apparatus, capable of improving the data transmission reliability. The method comprises: a terminal device receives first information from a network device, wherein a first field in the first information is used for indicating a first number of data streams sent according to a first pre-coding matrix and a second number of data streams sent according to a second pre-coding matrix; the terminal device determines a first demodulation reference signal (DMRS) port set and a second DMRS port set according to a third number and a second field in the first information, wherein the third number is equal to the sum of the first number and the second number; and the terminal device sends, to the network device, the first number of data streams according to the first DMRS port set, and sends, to the network device, the second number of data streams according to the second DMRS port set, wherein the number of DMRS ports comprised in the first DMRS port set is equal to the first number, the number of DMRS ports comprised in the second DMRS port set is equal to the second number, and the first number is not equal to the second number.
