Abstract: A remote UE transmits a first signaling for user registration of the remote UE into an MCPTT server. The MCPTT server detects a relationship of connection between the remote UE that transmitted the first signaling and a relay UE to which the remote UE is connected. Upon receiving voice data from a UE given a floor grant, the MCPTT server determines, as a destination UE of the voice data, only one of the relay UE and the remote UE that have the relationship of connection. The MCPTT server transmits the voice data with use of a unicast bearer for the destination UE. The relay UE transmits, to all of the remote UEs connected to the relay UE, the voice data that is transmitted from the MCPTT server.

Abstract: A network node (200), a wireless device (202) and methods therein, for decoding of contention based uplink transmissions of data in a cell served by the network node. The network node (200) registers the wireless device (202) for contention based uplink transmissions of data on a radio resource reserved for contention based uplink transmissions of data, e.g. when receiving a registration request sent from the wireless device, such that the wireless device (202) is included in a set (200a) of wireless devices being registered for contention based uplink transmissions of data on the radio resource in the cell. The network node (200) then performs blind decoding of uplink signals transmitted on the radio resource by considering the wireless devices in the set. In this way, the decoding is made more efficient by disregarding any other wireless devices in the cell which are not registered for contention based uplink transmissions of data on the radio resource in the cell.
