Embodiments herein relate to a method performed by a network node (110) for selecting a communication mode in a wireless communications network (100). The network node (110) obtains information about a first and a second wireless device (121, 122) in the wireless communications network (100) indicating that the first and the second wireless device (121, 122) are capable of communicating using any one of a set of at least three communication modes comprising at least a cellular communication mode, a Device-to-Device, D2D, half-duplex communication mode, and a D2D full-duplex communication mode. Also, the network node (110) selects, from the set of at least three communication modes, one of the communication modes for a communication between the first and second wireless devices (121, 122) when at least one criterion on a capability of the first and second wireless device (121) associated with one of the communication modes is met, and/or at least one criterion on an operational capability of the network node (110) associated with one of the communication modes is met. Then, the network node (110) transmits information about the selected communication mode for the communication between the first and second wireless devices (121, 122) to at least the first wireless device (121). Embodiments of the network node (110) are also described. Furthermore, embodiments herein further relate to a wireless device (110) and method therein for selecting a communication mode for a communication with a second wireless device (122) in a wireless communications network (100). |
