1. A first node for wireless communications, comprising:
a first receiver, receiving a first signaling, the first signaling being used for determining a first time-frequency resource block set and a second time-frequency resource block set; and
a first transmitter, transmitting a first signal, a first reference signal and a first demodulation reference signal in the first time-frequency resource block set; and transmitting a second signal, a second reference signal and a second demodulation reference signal in the second time-frequency resource block set;
wherein the first time-frequency resource block set and the second time-frequency resource block set are orthogonal; a measurement performed on the first demodulation reference signal is used for a demodulation of the first signal, a measurement performed on the second demodulation reference signal is used for a demodulation of the second signal; a third antenna port is an antenna port transmitting the first reference signal, a fourth antenna port is an antenna port transmitting the second reference signal, and both a port number of the third antenna port and a port number of the fourth antenna port are a target antenna port number; a first antenna port is an antenna port transmitting the first demodulation reference signal, and the third antenna port is associated with the first antenna port; a second antenna port is an antenna port transmitting the second demodulation reference signal, and the fourth antenna port is associated with the second antenna port; the first signaling comprises a fourth field, the fourth field comprised in the first signaling is a PTRS-DMRS association field; for the target antenna port number, the fourth field comprised in the first signaling indicates a port number of the first antenna port and a port number of the second antenna port; the first signaling is a DCI (Downlink Control Information) signaling, the first signal is transmitted on a Physical Uplink Shared CHannel (PUSCH), the second signal is transmitted on a PUSCH, the first signal and the second signal respectively comprise two repetitive transmissions of a first bit block, the first bit block comprises a positive integer number of bit(s); a first reference signal comprises a PTRS (Phase-Tracking Reference Signal), and the second reference signal comprises a PTRS; the target antenna port number is a non-negative integer; the first time-frequency resource block set comprises a positive integer number of time-frequency resource blocks that are orthogonal in frequency domain, the second time-frequency resource block set comprises a positive integer number of time-frequency resource blocks that are orthogonal in frequency domain, and the first time-frequency resource block set and the second time-frequency resource block set are orthogonal in time domain.
