    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 translation: 提供了由第一用户设备（121）执行的用于执行设备到设备D2D与第二用户设备（122）的通信的方法。 第一用户设备（121）确定在第一用户设备（121）中不存在有效的定时参考。 此外，第一用户设备（121）确定是否可以在D2D通信中使用预配置的时间提前量。 然后，当确定可以使用预配置的时间提前量时，第一用户设备（121）利用预配置的时间提前量的定时向第二用户设备（122）发送D2D信号以执行D2D通信。 还提供了用于启用无线电通信网络（100）中的用户设备（121,122）之间的D2D通信的用户设备（121），网络节点（110）及其中的方法。

    Abstract: The present disclosure relates to methods and to a wireless device, 10, 20, for enabling device-to-device communication. In particular the present disclosure relates to a method, performed in a radio node, of assigning resources for direct control signalling. The method comprises receiving, S1, from at least one further radio node, 160, sets of resources for direct control signalling in a respective cell or cluster. The method further comprises assigning, S2, resources for direct control signalling transmission within an area controlled by the radio node based at least on the received sets of resources, and transmitting, S3, to wireless devices controlled by the radio node, a message indicating resources assigned for direct control signalling. The disclosure also relates to the corresponding method in a wireless device and to a radio and to a wireless device implementing the methods, as well as to corresponding computer programs.

    Abstract: Embodiments are disclosed which improve the accuracy of measurement quantities obtained based on filtered measurements, by enabling filter memory reset events triggered by specific configuration and/or reconfiguration commands. According to some embodiments, a method for obtaining a measurement quantity is provided. The measurement quantity is based on a filtered reference signal (RS) measurement value. The method is executed in a wireless device, e.g. a user equipment (UE). According to the method, the wireless device receives (1410) a filter reset indication. In response to the indication, the wireless device resets (1420) one or more RS measurement filters. The wireless device then obtains (1430) a new filtered RS measurement value, and obtains (1440) the measurement quantity based on the new filtered RS measurement value.
