Resource selection for multiple destinations

A method associated with a wireless transmit/receive unit (WTRU), the method comprising:

• receiving information that indicates a first packet delay budget (PDB) associated with a first relay WTRU and a second PDB associated with a second relay WTRU;
• determining that there is data to be sent;
• determining a resource selection window based on one condition of a first condition or a second condition being satisfied, wherein the first condition being satisfied comprises that a congestion indication is received from the second relay WTRU and the second PDB is larger than the first PDB, and wherein the second condition being satisfied comprises that the congestion indication is not received from the second relay WTRU, the second PDB is larger than the first PDB, and a channel busy ratio (CBR) meets or is greater than a threshold;
• determining a resource within the determined resource selection window;
• and
• sending the data, wherein the data is sent via at least the determined resource.
