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: Systems, methods, apparatuses, and computer program products for configuring Channel State Information-Reference Signal (CSI-RS) resources of neighboring cells for inter-cell mobility are provided. One method may include providing, by a network node, at least one reporting configuration to one or more user equipment. The reporting configuration is based on at least one of channel state information reference signals (CSI-RS) or synchronization signal/physical broadcast channel (SS/PBCH) blocks. The method may also include receiving at least one measurement report comprising measurement results when and as specified by the at least one reporting configuration.

Abstract: A technique of performing a HO includes the source BS sending a HO resume message to the UE at the conclusion of a RACH access procedure that occurs in response to a HO command while a second TRX of the UE continues to exchange data packets with the source BS as if no HO command were issued. By continuing to exchange data with the source BS as if there were no HO command until the HO resume message reintroduces a RACH-less HO procedure, the interruption may be reduced to about 4 msec. At any point in time the UE handles only one protocol stack and only one security, which avoids the complexity of the advanced prior art methods.

Abstract: Methods and apparatus, including computer program products, are provided for conditional handovers. In some example embodiments, there may be provided a method including sending, by a first node serving a user equipment, a message to a second node, the message including an indication of whether a conditional cell change is prohibited at the second node; and receiving, by the first node, an acknowledgment in response to the message.

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.

Abstract: Systems, methods, apparatuses, and computer program products for source cell to provide a service/slice indication to the target cell in the handover preparation. The source cell provides to a target cell a list of one or more service/slice specific indications for individual ones of one or more network slices in a request for enhanced handover from the source cell to the target cell in a handover preparation phase. The source cell receives from the target cell, indications in a handover request acknowledgement of one or more selected network slices to be handed over from the source cell to the target cell using enhanced handovers. Performs make-before-break handovers to hand over these selected network slices from the source cell to the target cell and performs normal handovers for the one or more other network slices.
