Abstract
A user agent (UA) in a wireless communication system. The UA is configured to transmit a preamble on a random access channel (RACH) to an access node in order to attach to the access node. The UA transmits a message to the access node, wherein the message contains an identity of one or more relay nodes to which the UA can be transferred. The UA requests the access node to hand-over the UA to one relay node of the one or more relay nodes.
