Abstract

An apparatus such as a user equipment is in an embodiment of the invention configured to broadcast an access request to at least one neighboring node, the access request containing signature information indicating a user identifier, to check whether a collision indicator is received from a relay node, and to send another access request depending on a received collision indicator. The collision indicator may e.g. be a signature collision indicator, received from the node in case of colliding users, or a collision indicator of transmission received when transmissions of access requests are colliding at the node. A relay node may be configured to receive an access request from a user equipment, to detect a collision, and to inform the user equipment on a detected collision, indicating a type of collision.
