Method and device for non-terrestrial network (NTN) node selection in wireless communication

A second node for wireless communications, comprising:

• a second receiver, receiving a first message, the first message comprising a first measurement result and a second measurement result;
• a second transmitter, transmitting a first signaling;
• wherein a first-type measurement is performed, the first-type measurement being used to determine the first measurement result and the second measurement result;
• the first measurement result is associated with a first cell, while the second measurement result is associated with a second cell, the first cell and the second cell are respectively two different cells, and a RAT adopted by the first cell is the same as a RAT adopted by the second cell;
• the first message comprises a measurement report;
• at least one of a cell parameter of the first cell or a cell parameter of the second cell is used to determine an order of how the first measurement result and the second measurement result are arranged in the first message;
• the cell parameter comprises at least one of a cell type, a cell height, or a cell orbit or a cell delay wherein a first reference signal is received in the first cell, while a second reference signal is received in the second cell:
• a measurement for the first reference signal according to a first measurement quantity set is used to determine the first measurement result, while a measurement for the second reference signal according to the first measurement quantity set is used to determine the second measurement result;
• the first signaling indicates the first measurement quantity set, the first-type measurement being associated with the first measurement quantity set;
• the first measurement quantity set is used to determine the order of how the first measurement result and the second measurement result are arranged in the first message;
• the first measurement quantity set is related to signal quality.
