Abstract: Methods and apparatuses directed to non-access stratum procedures in connection with layer 2 relaying are provided. A method implemented in a first WTRU, may comprise: receiving, from a second WTRU, a first sidelink transmission comprising a first information indicating an amount of time for the first WTRU to refrain from transmitting, to the second WTRU; determining to reselect to a third WTRU responsive to receiving the first information and based on a second sidelink transmission from the third WTRU; reselecting or autonomous reselecting to the third WTRU; establishing a connection with the third WTRU; and transmitting, to the third WTRU, a third sidelink transmission comprising a second information indicating congestion as a cause for the reselection.
