Abstract: A technique includes transmitting a request for the delivery of multicast data; receiving the multicast data via a unicast data radio bearer or a multicast data radio bearer, wherein the user device is located in a first cell; receiving, by the user device from the base station, a connection suspend message, wherein the connection suspend message includes: information describing a radio access network (RAN) multicast area (RMA) for the delivery of the multicast data via a multicast data radio bearer, and a group identifier associated with the multicast data, wherein the RMA includes a list of one or more cells that has been updated by the base station to include the first cell where the user device is located; entering, by the user device, a low activity state in response to the connection suspend message; and, receiving, by the user device, the multicast data via the multicast data radio bearer.

Abstract: Methods and apparatus for handling a security aspect after cell reselection are disclosed. In a method a cell reselection is determined at a communication device that is in an intermediate radio resource control state where the communication device is inactive but connected to a radio access system. Subsequent to the determining, communication of security credential information is initiated with a selected cell of the radio access system while the communication device is in the intermediate radio resource control state. Communications with the selected cell are based on a security configuration according to the security credential information.

Abstract: For example, a communication link between a first relay node and a second relay node, which are in synchronous movement, is established. Beam management assistance information from the first relay node is received at the second relay node upon an occurrence of beam failure at the first relay node (S801). At the second relay node it is decided about a timing at which the received beam management assistance information is to be transmitted to a serving network node (S802), and the received beam management assistance information is transmitted from the second relay node to the serving network node at the decided timing (S803).
