Abstract: There is provided a method, computer program, and apparatus for causing an apparatus for a first access node to perform: establishing a connection towards a user equipment via a serving cell supported by the first access node; instructing the user equipment to obtain a first timing advance value for a target cell supported by a second access node, wherein the first timing advance value indicates a timing for transmitting uplink transmissions to the target cell; receiving, from the user equipment, an indication that the first timing advance value is or will soon be invalid; and determining whether to instruct the user equipment to obtain a second timing advance value for the target cell in dependence on the received indication, the second timing advance value being obtained later in time than the first timing advance value.

Abstract: Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for enhancement of HARQ feedback. The method comprises: upon receipt of data of at least one of a group of services from a second device, generating, at a first device, a Hybrid Automatic Repeat Request acknowledgement (HARQ-ACK) codebook comprising HARQ feedback and identification information for the at least one service, the group of services comprising at least one of multicast and broadcast services (MBSs) and unicast services; and transmitting the HARQ-ACK codebook to the second device. In this way, retransmissions of unicast and multicast services can be accurately scheduled in time, and unnecessary retransmissions can be avoided. In addition, the spectral efficiency and packet loss rate of the communication system can be improved.

Abstract: Embodiments of the present disclosure relate to frequency domain resource allocation for multicast traffic. A method comprises: receiving, at a first device and from a core network element, multicast traffic to be scheduled for a second device; generating assistance information for the second device, the assistance information enabling the second device to identify, within a bandwidth part configured for the second device, a frequency domain resource allocated for the multicast traffic; and transmitting the assistance GC information to the second device. The method further comprises: receiving, at the second device, the assistance information from a first device; and determining the frequency domain resource from downlink control information based on the assistance information. In this way, a significant flexibility to schedule multicast traffic can be provided, and a significant complexity reduction to a terminal device can be provided.

Abstract: Embodiments of the present disclosure relates to estimating downlink size for a multicast traffic. According to embodiments of the present disclosure, a first device receives downlink control information (DCI) for a multicast traffic. The first device determines field size(s) in the DCI based on one or more parameters which are associated with the field size estimation for the multicast traffic. The first device decodes the DCI based on the determined field sizes(s). In this way, the DCI can be blindly decoded correctly.

Abstract: A master node is provided for a user equipment operating in dual-connectivity with the master node and a secondary node. The master node may be configured to receive information that indicates supported network slices of one or more further nodes. The master node may be configured to transmit slice support information for the one or more further nodes, based on the information. The slice support information may indicate one or more of the supported network slices, at least one non-supported network slice of the one or more further nodes, or at least one communication session of the user equipment that is associated with at least one non-supported network slice. The secondary node may receive the slice support information, and make a secondary node change determination at the secondary node, based on the slice support information.
