Method and device in nodes used for wireless communication

A second node for wireless communications, characterized in comprising:

• a second receiver, receiving a first signal, the first signal used to indicate a first reference signal;
• and
• a second transmitter, transmitting a first signaling, the first signaling used to determine a first time;
• the second transmitter, transmitting a first-type channel in a first resource subset after the first time, the first-type channel being a Physical Downlink Control Channel (PDCCH);
• wherein the first reference signal is one of M reference signals, M being a positive integer greater than 1;
• after the first time, a transmitter of the first signal monitors the first-type channel in the first resource subset with same spatial parameters as those of a target reference signal;
• whether the target reference signal is the first reference signal is related to a type/types of a channel/channels carrying the first signal;
• when the type/types of the channel/channels carrying the first signal includes/include a first type, the target reference signal is the first reference signal;
• when the type/types of the channel/channels carrying the first signal does/do not include the first type, whether the target reference signal is the first reference signal is related to the first reference signal.
