Abstract

A method and apparatus for transmitting a reference signal and a communication system. The reference signal transmission method includes: a transmitter end generates one or more signals corresponding to the same transport block, the one or more signals including a data channel and a reference signal; and the transmitter end transmits the one or more signals in one or more time-domain resource segments, positions of reference signals being determined based on the one or more time-domain resource segments. The terminal equipment and the network device may be able to determine the positions of the reference signals in an actual repetition according to time-domain resource segments occupied by the actual repetition.
