The D2D enabled user equipment (12) supports D2D-communication with another D2D-enabled user equipment (15). The communication system (10) comprises a base station (15) serving one or more cellular user equipment (14) unable to support D2D communication. The D2D enabled user equipment (2, 15) and the cellular user equipment (14) share the same communication resources. The method (20) comprises: receiving (21), from the base station (13), configuration parameters comprising information on a reference signal pattern for use by the D2D enabled user equipment (12), and transmitting (22), based on the configuration parameters, cellular reference signals, enabling the cellular user equipment (14) to measure and report, to the base station (13), channel information on a channel from the D2D enabled user equipment (12) to the cellular user equipment (14). The invention also relates to D2D user equipment, methods in a base station, base station, computer programs and computer program products.

    Abstract: A method performed by a first user equipment (121) for performing Device-to- Device, D2D, communications with a second user equipment (122)is provided. The first user equipment (121) determines that a valid timing reference is not present in the first user equipment (121). Also,the first user equipment (121) determines whether a preconfigured timing advance can be used in the D2D communication. Then, when determined that the preconfigured timing advance can be used, the first user equipment (121) transmits a D2D signal to the second user equipment (122) with a timing using the preconfigured timing advance to perform D2D communication. A user equipment (121), a network node (110)and method therein for enabling D2D communications between user equipments (121, 122) in a radio communications network (100) are also provided.

    Abstract: A method, a user equipment, base stations for performing random access procedures in a network including a high power base station, a low power base station and a user equipment are provided, wherein the user equipment is in connection with the high power base station in a downlink direction and is in connection with the low power base station in an uplink direction. The method comprises performing, by the user equipment, the random access procedure with the low power base station if the random access procedure is initiated by the user equipment. The method further comprises performing, by the user equipment, the random access procedure with the high power base station if the random access procedure is initiated by the high power base station. With the present invention, the duration of the random access procedure conducted under the decoupled downlink/uplink scenario can be significantly shortened.
