Title:
DATA TRANSMISSION METHOD, TERMINAL DEVICE AND NETWORK DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/192530
Kind Code:
A1
Abstract:
Provided are a data transmission method, a terminal device and a network device. The method comprises: a terminal device acquiring first indication information at an Nth sending time, wherein the first indication information is used to indicate whether a first port used to send a first signal is the same as a second port used to send a second signal, and the second signal is sent by the terminal device at an N-K sending time, N and K are both positive integers, and N is greater than K; and the terminal device sending the first signal according to the first indication information. The first port comprises at least one of the following pieces of information: a first antenna port used to send the first signal, a first precoding matrix used to send the first signal, and a first spatial filter used to send the first signal. The data transmission method, the terminal device and the network device in the embodiments of the present application facilitate improving the reliability of data transmission.
