In accordance to embodiments, methods, devices, and systems for determining initial transmissions in grant-free transmissions are disclosed. A UE receives a resource configuration for grant-free (GF) transmissions. The resource configuration comprises a periodicity parameter (P), a repetition number (K), and a sequence of redundancy version (RV) numbers corresponding to one or more RV types. The periodicity parameter defines a period having K transmission occasions (TOs), and each of the KTOs is associated with one RV number in the sequence of RV numbers. The UE performs an initial GF transmission of data in a TO of the K TOs in the period defined by the periodicity parameter. The TO is associated with an RV number corresponding to RV0.

A vertically integrated slice management system is provided that can leverage dynamic alliances of access layer, core layer, and service layer services. The system can instantiate a vertical slice that incorporates one or more services and network functions from a selection of layer slices in order to provide a streamlined and efficient mechanism for serving a user device based on the type of the user device, and the type of service requested.

A method and apparatus for robust adjustment of access and mobility management functions are disclosed. In one embodiment, a method includes: receiving a radio access network (RAN)-user equipment (UE) identifier from a first access and mobility management function (AMF), the RAN-UE identifier configured to identify a UE or UE context for a RAN; producing an AMF-UE identifier, the AMF-UE identifier configured to identify the UE or UE context for a second AMF; selecting a transport network layer association (TNLA) link towards a RAN; and sending the AMF-UE identifier to the RAN.

For example, certain embodiments may benefit from an improved signaling of control messages in 5G or New Radio systems between a donor node and a plurality of integrated access and backhaul nodes. A method may include generating at a network node a control message for a plurality of other nodes. The method may also include transmitting the control message from the network node to the plurality of other nodes via a multicast radio bearer. The multicast radio bearer may connect the plurality of other nodes.

Systems and methods for signaling information related to wireless device positioning in a cellular communications network are disclosed. In some embodiments, a method of operation of a first network node for signaling information related to wireless device positioning in a cellular communications network comprises signaling, from the first network node to a second node, information comprising information that relates to a new vertical surface model for a plurality of cells in a cellular communications network. The new vertical surface model is a translated and scaled version of an initial vertical surface model.

The present disclosure is directed to method in a mobility management node and such a node for delivering data to a wireless communication device (WCD) served by the mobility management node, operating in a communication network comprising a network entity (NE) and a radio access network (RAN) node serving the WCD, the method comprises: obtaining capability information indicating whether the RAN node supports acknowledgement of a successful delivery of data to the WCD; receiving a data message sent by the NE comprising user data intended for the WCD; sending a control plane message comprising the user data to the RAN node for further delivery to the WCD; sending a response to the NE indicating the outcome of the data delivery.
