An embodiment of a user equipment supports conditional handovers to one or more cells of a cellular network. The user equipment is configured to receive configuration data from the cellular network. The configuration data indicates for a plurality of target cells of the cellular network, conditions to trigger a conditional handover to any of the target cells. The user equipment is further configured to check the conditions with respect to appliance, and, in case of appliance, trigger the conditional handover.

HARQ process / entity based uplink multiplexing

The present invention concerns a novel form of communication within a cellular wireless communication network. One aspect of the invention concerns a User Equipment for a cellular network, wherein the UE inter alia includes a first interface for UE-to-Basestation communication configured to communicate with a base station of the cellular network and a second interface for UE-to-UE communication configured to communicate with one or more other UEs of a UE-Group to which the UE belongs. According to the invention the UE is configured to receive via its first interface configuration data for configuring its second interface, and to coordinate, via the second interface, a communication within the UE Group.

UE groups, UE group manager UEs and UE group member UEs

A wireless communication system includes a plurality of user devices, UEs, and at least one logical group defined in accordance with one or more logical group criteria. The logical group includes a plurality of member UEs to be connected via sidelink for sidelink communication with each other, and all member UEs of the logical group have assigned the same destination identification, ID, the destination ID being unique for the logical group.

A user equipment for a mobile communication network is provided. The mobile communication network has a radio access network including a plurality of cells and being configured to serve the user equipment within a cell. To receive a data packet from the radio access network, the user equipment is configured to receive a plurality of different versions of the data packet transmitted by the radio access network to the user equipment in parallel via different physical resources. To provide a data packet to the radio access network, the user equipment is configured to provide a plurality of different versions of the data packet and to transmit the plurality of different versions of the data packet to the radio access network in parallel via different physical resources.

A concept for handovers in cellular networks, a concept for improved handling of tracking/paging areas for, for instance, user entities in inactive modes and a concept for enabling intelligent route selection in cellular networks are presented.

Preemptive handover preparation and tracking/paging area handling and intelligent route selection in a cellular network

A wireless communication system includes a plurality of user devices, UEs, configured for a sidelink communication using resources from a set of sidelink resources of the wireless communication system. The plurality of UEs includes at least one transmitting UE and at least one receiving UE, the transmitting UE and the receiving UE configured to use at least a subset of the sidelink resources of the wireless communication system for the sidelink communication. The wireless communication system is configured to allow a data duplication on the sidelink, wherein the data duplication on the sidelink is activated or triggered dependent on one or more of a sidelink quality of the sidelink between the transmitting UE and the receiving UE, and/or an occupancy of the sidelink resources, and/or data received by a network element/network function, and/or the application service running on one of the UEs.

NR V2X reliability enhancements

In the field of mobile communication systems, techniques relating to checking or verifying if information sent by a transmitter has been correctly received at a receiver so as to initiate a retransmission in case of a non-successful transmission of the information are described. Embodiments relate to simultaneous synchronous and asynchronous HARQ, hybrid automatic repeat request, operations in a network entity of the wireless communication system, like a base station or a user equipment, UE. In particular, an approach for reliably handling retransmissions in a wireless communication system for data or information associated with different services types is described.

A base station for a wireless communication network comprising a plurality of logical radio access networks, wherein the base station is configured to communicate with a plurality of users to be served by the base station for accessing one or more of the logical radio access networks, and the base station is configured to selectively control the physical resources of the wireless communication network assigned to the logical radio access networks and/or to control access of the users or user groups to one or more of the logical radio access networks, wherein, during a first operation mode of the wireless communication network, the base station is configured to allow access of users or user groups of one or more of the logical radio access networks (e.g., eMBB, URLLC, eMTC), and wherein, during a second operation mode of the wireless communication network, the base station is configured to adaptively limit access of users or user groups to one or more of the logical radio access networks, and/or adaptively reduce a number of enabled logical radio access networks.

Access control for network slices of a wireless communication system

Radio access network controller-based mobility optimization is disclosed. Mobility reports are received at a radio access network controller from multiple network node devices, each mobility report reporting at least one individual failure event to complement one or more aggregated mobility event counters and/or one or more aggregated performance measurement reports. The mobility reports are related to client devices in one or more service areas. The radio access network controller analyzes the received mobility reports. In response to the analyzing resulting in a perceived need for an update of a cell configuration of a service area of the one or more service areas, the radio access network controller determines updated cell configuration information for the service area. The updated cell configuration information is transmitted from the radio access network controller to-wards at least one network node device in the service area.
