Configuration method for resource sharing among multiple wireless links, signal transmission method and node

A configuration method for resource sharing among multiple wireless links, the multiple wireless links comprising a first link and a second link, or comprising a first link, a second link and a third link,

• wherein the method comprising:
• performing P-Q configuration on a set N formed by a group of continuous units, and determining a set P configured for downlink transmission of the second link and a set Q configured for uplink transmission of the second link in the set N;
• performing
• U-V configuration on the set N, and determining a set U configured for downlink transmission of the first link and a set V configured for uplink transmission of the first link in the set N;
• and
• determining a set S for uplink transmission of the second link and downlink transmission of the second link;
• or, the method comprising:
• performing P-Q configuration on a set N formed by a group of continuous units, and determining a set P configured for downlink transmission of the third link and a set Q configured for uplink transmission of the third link in the set N;
• performing U-V configuration on the set N, and determining a set U configured for downlink transmission of the third link and a set V configured for uplink transmission of the third link in the set N;
• and determining a set S for uplink transmission of the third link and downlink transmission of the third link;
• wherein the units are time units, the set P and the set Q are not intersected, the set U and the set V are not intersected and both belong to a set M, where the set M=N−(P+Q), and the set S=M−(U+V),
• wherein the first link is a link between a first node and a second node;
• the second link is a link between the second node and a third node;
• the third link is a link between the first node and the third node;
• and directions from the first node to the second node and the third node and from the second node to the third node are downlink directions of corresponding links, and opposite directions of the downlink directions are uplink directions of the corresponding links.
