Method for improving or enabling radio coverage for a user equipment with respect to a mobile communication network, wherein the mobile communication network comprises a core network and an access network, wherein the access network of the telecommunications network comprises a base station entity, wherein the user equipment is enabled to use a device to device communication mode D2D mode wherein a relay user equipment is likewise enabled to use device to device communication mode, wherein the base station entity transmits a timing information related to a master timing schedule relevant for any user equipment being served by the base station entity, wherein the base station entity furthermore transmits an indication related to a discovery time interval, the discovery time interval being used for discovery signals exchanged between user equipments being enabled to use the device to device communication mode and using the device to device communication mode, wherein -- in case that the relay user equipment is connected to the base station entity, and -- in case that the user equipment - at a given point in time - has been connected to the base station entity or to another base station entity of the access network of the mobile communication network but is out of direct radio coverage with the base station entity at a further point in time, the further point in time being subsequent to the given point in time, the method comprising the following first and second step: -- in the first step, the user equipment transmits a first discovery signal, the first discovery signal being received by the relay user equipment and the first discovery signal -- being subject to a time limitation with respect to the discovery time interval, wherein the time limitation of the first discovery signal corresponds to avoiding a first part and a second part of the discovery time interval, the first part of the discovery time interval including the beginning of the discovery time interval and the second part of the discovery time interval including the end of the discovery time interval, and/or -- comprising a synchronization indication, the synchronization indication being related to an estimated timer deviation of a timer within the user equipment with respect to the master timing schedule of the base station entity, -- in the second step, subsequent to the first step, the relay user equipment - upon reception of the first discovery signal from the user equipment - applies reception capabilities during a first reception time interval, the first reception time interval comprising but exceeding the discovery time interval in time, wherein the first reception time interval is dependent on the time limitation and/or the synchronization indication of the first discovery signal, -- in case that the relay user equipment is connected to the base station entity, and -- in case that the user equipment - at a given point in time - has been connected to the base station entity or to another base station entity of the access network of the mobile communication network but is out of direct radio coverage with the base station entity at a further point in time, the further point in time being subsequent to the given point in time, -- in the first step, the user equipment transmits a first discovery signal, the first discovery signal being received by the relay user equipment and the first discovery signal -- being subject to a time limitation with respect to the discovery time interval, wherein the time limitation of the first discovery signal corresponds to avoiding a first part and a second part of the discovery time interval, the first part of the discovery time interval including the beginning of the discovery time interval and the second part of the discovery time interval including the end of the discovery time interval, and/or -- comprising a synchronization indication, the synchronization indication being related to an estimated timer deviation of a timer within the user equipment with respect to the master timing schedule of the base station entity, -- being subject to a time limitation with respect to the discovery time interval, wherein the time limitation of the first discovery signal corresponds to avoiding a first part and a second part of the discovery time interval, the first part of the discovery time interval including the beginning of the discovery time interval and the second part of the discovery time interval including the end of the discovery time interval, and/or -- comprising a synchronization indication, the synchronization indication being related to an estimated timer deviation of a timer within the user equipment with respect to the master timing schedule of the base station entity, -- in the second step, subsequent to the first step, the relay user equipment - upon reception of the first discovery signal from the user equipment - applies reception capabilities during a first reception time interval, the first reception time interval comprising but exceeding the discovery time interval in time, wherein the first reception time interval is dependent on the time limitation and/or the synchronization indication of the first discovery signal,
