Abstract: Methods, apparatuses, and computer program products for providing uniform user equipment initialization procedure for both in-coverage and out-of-coverage device-to device communications are disclosed herein, incorporating a novel tri-timer design: an initial timer, a search timer, and an active timer. In a method a determination is made regarding a user equipment as being a clusterhead candidate which can act as a clusterhead of a cluster. The user equipment searches for a suitable cell or cluster to join. If a suitable cell or a cluster is not found, the user equipment is selected to be a clusterhead which will act as the clusterhead of its own cluster. After selecting the user equipment to be a clusterhead and establishing its cluster, the user equipment transmits a discovery signal which alerting other user equipment to the clusterhead, to which the other user equipment can join. The user equipment as clusterhead then maintains the cluster.
