Abstract: A method and apparatus for cross link (XL) establishment and maintenance are disclosed in which the XL enables direct communication between the LTE WTRU and the another LTE WTRU. In the method and apparatus, a XL between a Long Term Evolution (LTE) terminal wireless transmit/receive unit (T-WTRU) and an LTE helper WTRU (H-WTRU) is established and maintained. The T-WTRU is configured to maintain the XL while in an XL-idle substate in which data communication on the XL is disabled. A receiver of the T-WTRU is configured to receive a first keep alive message on the XL in the XL-idle substate, and, on a condition that the first keep alive message is received, at least one processor of the T-WTRU is configured to maintain the XL.
