Method and device in nodes used for wireless communication

A second node for wireless communications, comprising:

• a second transmitter, transmitting a first information;
• and
• a second receiver, receiving first CSI;
• wherein the first information block is used to indicate a first RS resource set, the first RS resource set comprises at least one RS resource;
• a measurement on the first RS resource set is used to generate the first CSI, the first CSI comprises a first information set and a second information set, the first information set comprises at least one first-type information group, and the second information set comprises at least one information group;
• both the first-type information group and the second information set comprise at least one CSI report quantity, the first-type information group corresponds to a first bandwidth, and a priority of the first-type information group is higher than a priority of any information group in the second-type information set;
• first channel information belongs to the first CSI, and a type of the first channel information is either PMI or first type, where the PMI is codebook-based and the first type is non-codebook-based;
• the type of the first channel information is used to determine a number of the first-type information group(s) comprised in the first information set.
