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 is used for determining a port number of the first antenna port and a port number of the second antenna port.
