Abstract: A method performed in a communication device for handling a resume procedure from a power saving mode of operation to a connected mode of operation is disclosed. The communication device is configured with multi-radio dual connectivity (MR-DC) with a first cell group and a second cell group in a wireless communication network. The method comprises initiating (13010) a resume procedure when there is an uplink (UL) data available at the communication device while it is in the power saving mode of operation; setting (13050, 13060) an UL data indication indicating whether the UL data is available for the first cell group or the second cell group; and transmitting (13070) the UL data indication to a network node.

Abstract: A wireless device configured to acquire network support information associated with a neighbor cell, wherein the network support information indicates that the neighbor cell supports a Stand-Alone (SA) mode of operation and/or a Non-Stand-Alone (NSA) mode of operation; and transmit to a serving network node a report comprising identification information associated with the neighbour cell and the network support information indicating that the neighbor cell supports a SA mode of operation and/or a NSA mode of operation. A serving network node configured to receive a report transmitted by a wireless device, wherein the report comprises identification information associated with the neighbor cell and network support information indicating that the neighbor cell supports a Stand-Alone (SA) mode of operation and/or a Non-Stand-Alone (NSA) mode of operation; and determine, based on the report, a type of interface to establish between the serving network node and the neighbor network node.

Abstract: A method in a network node for transmitting a cell identifier to identify a source for one or more beamed transmissions includes determining a cell identifier (CID) of the network node. The method also includes determining a beam identifier (BID) of a beam of the network node. The method further includes linking the CID and the BID and transmitting the BID and the CID to one or more user equipment (UE).
