1. A method in a User Equipment (UE) for wireless communications, comprising:
receiving a first signaling, the first signaling comprises downlink control information (DCI); and
transmitting a first radio signal, the first radio signal is transmitted on a physical uplink shared channel (PUSCH);
wherein the first signaling comprises scheduling information of the first radio signal;
a first reference signal is used to determine at least one of transmitting power of the first radio signal or one or more antenna ports for transmitting the first radio signal;
wherein determination of an antenna port for transmitting the first radio signal comprises: using the first reference signal to determine a spatial domain transmission filter corresponding to the first radio signal;
a first radio resource is associated with the first reference signal, the first radio resource is a physical uplink control channel (PUCCH) resource, and the first radio resource is related to the first signaling;
the first signaling does not comprise a first field, and the first field is a sounding reference signal (SRS) resource indicator field, the first field indicating one or more antenna ports for transmitting a radio signal scheduled by a signaling to which the first field belongs; and
the first radio resource is related to the first signaling by using a time-frequency resource occupied by the first signaling to determine the first radio resource.
