Method and device in communication nodes for wireless communication

A second node for wireless communications, comprising:

• a second processor, receiving a first signal set;
• wherein time-domain resource(s) occupied by one or more signals comprised in the first signal set is(are) used for determining a first time window;
• the first signal set comprises a first signal, the first signal comprising a first sub-signal and a first reference signal;
• the first sub-signal comprises a first field, and the first field of the first sub-signal is used for triggering a first CSI report;
• a first condition set is used for determining whether a transmitter of the first signal set is allowed to trigger a second CSI report in the first time window;
• when the first condition set is fulfilled, the transmitter of the first signal set is not allowed to trigger the second CSI report in the first time window;
• when the first condition set is not fulfilled, the transmitter of the first signal set is allowed to trigger the second CSI report in the first time window;
• the first condition set comprises at least one of a first condition or a second condition;
• the first condition comprises that a number of signals comprised in the first signal set is no less than a first threshold;
• the second condition comprises that a first index is equal to a second index, the first CSI report is associated with the first index, and the second CSI report is associated with the second index.
