The present disclosure provides a method and device in a node for wireless communications. A first node receives a first signaling; and operates a first signal group. The first signaling is used for determining a first reference-signal-resource set; a first parameter-group set comprises a positive integer number of parameter group(s), any parameter group in the first parameter-group set is used for the operating action of a signal in the first signal group; any reference signal resource in the first reference-signal-resource set is used for determining a parameter group in the first parameter-group set. The above method unifies beam management mechanisms for both Uplink and Downlink, which improves performance of Uplink transmission and reduces corresponding signaling overhead and delay.
