A method performed, by a first user equipment, UE, in a wireless communication system, the method comprising: establishing a connection with an eNodeB, eNB, which broadcasts D2D control information; receiving information on one of an evolved-UMTS terrestrial radio access network, E-UTRAN, planned mode or a UE autonomous mode from the eNB, wherein the E-UTRAN planned mode is a mode in which the eNB is responsible for radio resources for a D2D connection, wherein the UE autonomous mode is a mode in which the first UE is responsible for radio resources for the D2D connection, wherein the information is received via a radio resource control, RRC, message on a dedicated control channel, DCCH, and wherein the RRC message includes a common configuration for the D2D connection; when the information on the E-UTRAN planned mode is received: broadcasting a control signal on a D2D broadcast control channel, D-BCCH, by using a D-BCCH configuration contained in the common configuration for the D2D connection based on the D2D control information; receiving a D2D connection request message from a second UE, wherein the D2D connection request message includes an identifier of the second UE; transmitting the received D2D connection request message to the eNB; receiving a D2D connection setup message from the eNB; transmitting the D2D connection setup message to the second UE, wherein the D2D connection setup message includes a cell radio network temporary identifier, C-RNTI, allocated for the second UE and a serving cell identifier for the first UE; receiving a D2D connection setup complete message from the second UE, wherein the D2D connection setup complete message includes a serving cell identifier for the second UE; and delivering the received D2D connection setup complete message to the eNB to finalize establishment of the D2D connection. establishing a connection with an eNodeB, eNB, which broadcasts D2D control information; receiving information on one of an evolved-UMTS terrestrial radio access network, E-UTRAN, planned mode or a UE autonomous mode from the eNB, wherein the E-UTRAN planned mode is a mode in which the eNB is responsible for radio resources for a D2D connection, wherein the UE autonomous mode is a mode in which the first UE is responsible for radio resources for the D2D connection, wherein the information is received via a radio resource control, RRC, message on a dedicated control channel, DCCH, and wherein the RRC message includes a common configuration for the D2D connection; when the information on the E-UTRAN planned mode is received: broadcasting a control signal on a D2D broadcast control channel, D-BCCH, by using a D-BCCH configuration contained in the common configuration for the D2D connection based on the D2D control information; receiving a D2D connection request message from a second UE, wherein the D2D connection request message includes an identifier of the second UE; transmitting the received D2D connection request message to the eNB; receiving a D2D connection setup message from the eNB; transmitting the D2D connection setup message to the second UE, wherein the D2D connection setup message includes a cell radio network temporary identifier, C-RNTI, allocated for the second UE and a serving cell identifier for the first UE; receiving a D2D connection setup complete message from the second UE, broadcasting a control signal on a D2D broadcast control channel, D-BCCH, by using a D-BCCH configuration contained in the common configuration for the D2D connection based on the D2D control information; receiving a D2D connection request message from a second UE, wherein the D2D connection request message includes an identifier of the second UE; transmitting the received D2D connection request message to the eNB; receiving a D2D connection setup message from the eNB; transmitting the D2D connection setup message to the second UE, wherein the D2D connection setup message includes a cell radio network temporary identifier, C-RNTI, allocated for the second UE and a serving cell identifier for the first UE; receiving a D2D connection setup complete message from the second UE, wherein the D2D connection setup complete message includes a serving cell identifier for the second UE; and delivering the received D2D connection setup complete message to the eNB to finalize establishment of the D2D connection.
