Methods and apparatus for sidelink transmission muting

A first wireless transmit/receive unit (WTRU) comprising:

• a transceiver;
• and
• a processor;
• wherein the transceiver and processor are configured to:
• receive configuration information, the configuration information including a sidelink positioning reference signal (SL-PRS) muting threshold;
• receive a first scheduling information for a first SL-PRS transmission from a second WTRU, wherein the second WTRU is in a positioning group;
• receive a second scheduling information for a second SL-PRS transmission, from a third WTRU, wherein the third WTRU is not in the positioning group;
• determine, based on the first scheduling information, the second scheduling information, and the muting threshold, that the second SL-PRS transmission will interfere with the first SL-PRS transmission;
• and
• transmit, to the third WTRU, a muting indication, the muting indication including a muting pattern.
