1. A first node for wireless communications, comprising:
a first transmitter, transmitting a first signaling; and
a second transmitter, transmitting a first reference signal and a second signal through a first antenna port in a first time-frequency resource set;
wherein the first signaling is used to indicate the first time-frequency resource set, and the first signaling is used to indicate a number of time-frequency resource(s) used for the first reference signal in the first time-frequency resource set; the first reference signal is used to demodulate the second signal; the first antenna port conforms to a first Quasi Co-Located (QCL) relation, and the first QCL relationship is one of Q candidate QCL relationships; any of the Q candidate QCL relationships comprises at least one of a candidate reference signal or a QCL type; the number of time-frequency resource(s) used for the first reference signal in the first time-frequency resource set is used to indicate the first QCL relationship out of the Q candidate QCL relationships, Q being a positive integer greater than 1; wherein a first receiver receives second information, the second information and the number of time-frequency resource(s) used for the first reference signal in the first time-frequency resource set are used together to determine Q0 candidate QCL relationship(s) out of the Q candidate QCL relationships, and the first information is used to determine the first QCL relationship out of the Q0 candidate QCL relationship(s).
