17. An apparatus for transmitting a reference signal, configured in a terminal equipment, the apparatus comprising,
processor circuitry configured to generate one or more actual repetitions corresponding to the same transport block, each of the one or more actual repetitions comprising a data channel and a reference signal;
a transmitter configured to transmit the one or more actual repetitions in one or more time-domain resource segments in which the one or more actual repetitions are located, positions of reference signals in the one or more actual repetitions being determined based on the one or more time-domain resource segments in which the one or more actual repetitions are located; and
a receiver configured to, before the transmitter transmits the signal, receive a command transmitted by a network device, the command configuring or indicating repetition of a data channel or a transport block, wherein
the command configuring or indicating repetition of a data channel or a transport block comprises: configuring or indicating the repetition of the transport block by the network device via higher layer signaling and downlink control information, the higher layer signaling comprising a third parameter, the third parameter configuring or indicating the repetition of the transport block, and the downlink control information comprising an indication field, the indication field indicating whether to enable the repetition, and the indication field indicating dynamic switching between a first repetition and a second repetition,
the first repetition corresponds to R15 repetition, and
the second repetition corresponds to R16 repetition.
