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: 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: Improved techniques of beam management in a HO situation include receiving, at a source node from a candidate target node after receiving a measurement report from a UE prior to completion of a HO, a repetition configuration of a channel state information reference signal (CSI-RS) resource index to be used by the UE for random access. When beam refinement occurs during HO, a candidate target cell for HO provides the UE with a repetition configuration of CSI-RS resource index that will be selected and used by the UE for random access to the target cell. When beam refinement occurs before HO, the candidate target cell of handover provides the UE (e.g. during the handover preparation phase in case of conditional HO (CHO)) with the repetition configuration of CSI-RS resource index (or indices) whose transmission(s) is repeated while the UE is served by the source cell and before executing a handover.

Abstract: For a UE in a wireless network and able to communicate via sidelink communications with other UE(s), the UE determines whether a specific condition exists indicating the UE has limited availability of CG resources used to communicate for the sidelink communications. The UE sends, using the sidelink communications, a message indicating the limited availability of the CG resources toward the other UE(s). Another UE receives the message indicating a limited availability of CG resources for the UE, and prepares an application in the other UE for a less sensitive mode of operation having less QoS than a mode having a normal QoS. A base station can configure the UE with the CG resources and provide a set of parameters to the UE to be used to form the message for the user equipment to transmit to the other UE(s) using sidelink communications.

Abstract: A method and apparatus may include receiving, by a master node involved in multi-connectivity, at least one indication from a user equipment upon or after at least one condition for conditional cell change is fulfilled that it has detached from at least one source PSCell of a secondary node. The method may further include transmitting, by the master node, at least one SgNB Release Request to the source Secondary Node such that the secondary node stops transmission and reception on the source PSCell and/or initiates data forwarding to the target SN or to the MN. The method may further include receiving, by the master node, at least one SgNB Release Request Acknowledge from the source Secondary Node. The method may further include forwarding, by the master node, user data to the target secondary node upon receiving an indication from the user equipment.

Abstract: An example embodiment relates to Random Access Channel, RACH, procedure, for example in the New Radio, NR. Random access procedures may be of two types, contention based CBRA and contention free, CFRA. A client device may only perform CBRA fallback when none of the reference signal received strengths, RSRPs, of the synchronization signal blocks, SSBs, which is associated with the CFRA resources is above a predefined threshold, T1. All SSBs and CSI-RS with associated CFRA resources may be below the threshold. Then, the client device may select an SSB or CSI-RS according to a predefined rule and perform CFRA when CFRA resources are associated. Devices, methods and computer programs are disclosed accordingly.

Abstract: There are provided measures for enabling/realizing flexible and adaptive QoS monitoring for unicast/groupcast over sidelink communication, which may preferably be capable of enhancing support of unicast/groupcast services over sidelink communication. Such measures exemplarily comprise obtaining a request for QoS monitoring for unicast/groupcast over sidelink communication with a specified quality-of-service profile, which indicates at least one target QoS metric to be monitored, determining a QoS monitoring procedure, wherein a scheme for enforcing QoS monitoring over sidelink communication in collaboration with at least one unicast/groupcast receiving-side device is decided, and performing the QoS monitoring procedure, wherein QoS monitoring messages are exchanged with the at least one unicast/groupcast receiving-side device over the sidelink communication with the specified QoS profile in accordance with the decided scheme and the at least one target quality-of-service metric is derived based thereon.
