Document Type and Number:
WIPO Patent Application WO/2018/127112
Kind Code:
A1
Abstract:
The present application relates to a data transmission method and apparatus. The method comprises: a first device sending first indication information, wherein the first indication information is used for indicating a time frequency resource of a first reference signal, and the first reference signal is used for carrying out channel estimation on retransmission data of first data; and the first device sending the retransmission data. When a time frequency resource occupied by a reference signal and indicated by the first indication information is less than a time frequency resource occupied by a reference signal and used during first transmission of the first data, the overhead of a reference signal can be saved on, and the flexibility of resource configuration of the reference signal and data transmission efficiency are improved.
