Abstract: A method, apparatus, and a computer-readable storage medium are provided for forwarding of buffered user data at a target node to a re-establishment node. In an example implementation, the method may include receiving, by a first network node, a handover cancel or an Xn-User plane address indication message from a second network node, the handover cancel or the Xn-User plane address indication message including tunnel addresses for one or more data radio bearers; and forwarding, by the first network node, buffered downlink packets to a third network node or the second network node, the forwarding based at least on the tunnel addresses. In an additional example implementation, the method may include sending, by a third network node, tunnel addresses for one or more data radio bearers to a second network node upon re-establishing of a radio resource control connection; and receiving, by the third network node, buffered packets at the first network node from a second network node or the first network node. In an additional example implementation, the method may include initiating, by a user equipment, a radio resource control re-establishment procedure with a third network node, the re-establishment procedure is initiated upon a handover failure of the user equipment from a second network node to a first network node; and receiving, by user equipment, buffered packets at the first node from a third network node.

Abstract: The example embodiments of the invention provide at least a method and apparatus to perform determining, by a network node of a communication network, information including a conditional handover configuration and a target dual active protocol stack handover configuration for a handover of user equipment in the communication network, wherein the information includes at least one triggering condition associated with the handover to be met for application of the target dual active protocol stack handover configuration for the handover; and sending toward the user equipment the information for use by the user equipment with the handover. In addition, example embodiments of the invention provide at least a method and apparatus to perform receiving, by a user equipment of a communication network, from a network node information including a conditional handover configuration and a target dual active protocol stack handover configuration for use with a handover of the user equipment in the communication network, wherein the information includes at least one triggering condition associated with the conditional handover to be met for application of the target dual active protocol stack handover configuration for the handover; and based on the information, performing operations for the handover.

Abstract: Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of extended bandwidth allocation. In example embodiments, a first device receives, from a second device, an indication of a reference bandwidth. The first device receives, from the second device, an indication of a bandwidth extended from the reference bandwidth and receives, from the second device, an indication of at least one frequency offset of a first set of narrowbands with respect to a second set of narrowbands associated with the reference bandwidth. Then, the first device determines, based on the reference bandwidth, the extended bandwidth and the at least one frequency offset, the first set of narrowbands for communication with the second device.

Abstract: It is provided a method comprising: checking if an indication indicates that a target cell is configured to store concurrently first and second configurations of a terminal, wherein the first configuration is based on a first conditional handover request, and the second configuration data set is based on a second conditional handover request; monitoring if the source cell intends performing a radio reconfiguration of the terminal after the source cell configured the terminal for the first conditional handover; canceling the first conditional handover if the source cell intends performing the radio reconfiguration and the indication does not indicate the concurrently storing; instructing the source cell to request the second conditional handover from the target cell if the source cell intends performing the radio reconfiguration and the indication indicates the concurrently storing.

Abstract: Embodiments of the present disclosure relate to the resource configuration for Narrow Band Internet of Thing (NB-IoT). A method of resource configuration for NB-IoT includes determining, at a network device, whether a configured Uplink Resource (PUR) for transmission from a terminal device to the network device is to be adjusted; in response to determining that the PUR is to be adjusted, determining a set of resources to be allocated for further transmission from the terminal device to the network device based on a Transport Block Size (TBS) associated with the further transmission; generating reconfiguration information of the PUR based on the set of the resources; and transmitting the reconfiguration information to the terminal device. In this way, the resource configuration may be determined and adjusted more efficiently and flexibility compared to the conventional way.
