Method and device used for UE and base station in wireless communication

A method in a base station for wireless communications, comprising:

• transmitting a first signaling, the first signaling comprises DCI;
• and
• receiving a first radio signal, the first radio signal is transmitted on a 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;
• 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 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 an 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;
• 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.
