Abstract: A user device, UE, for a wireless communication network, acta as a relay UE so as to provide functionality to support connectivity between a transmitting entity and one or more receiving entities of the wireless communication network. The UE differentiates a transmission, which is received from the transmitting entity, between a first transmission to be relayed to a receiving entity and a second transmission that is intended for the UE. The UE differentiates the received transmission by control information associated with the transmission and/or resources on which the transmission and/or the associated control information is received.
