    Abstract: Wireless User Equipment, UE, and network apparatuses may be adapted to facilitate continuity of Multicast/Broadcast Service, MBS, across cells. A UE in idle/inactive mode, for example, may receive MBS assistance information comprising scheduling information defining MB S reception windows and perform a cell re selection evaluation process accordingly. An UE in connected mode may conduct and report MB S quality measurements and receive an RRC reconfiguration comprising an MB S configuration for a target cell, determine that MBS transmission progress differs between the source cell and the target cell, and recover lost MBS PDUs or delete duplicate MBS PDUs accordingly. A network apparatus, such as a gNB for example, may map a GPRS Tunneling Protocol Sequence Number of an MBS PDU, to a Packet Data Convergence Protocol Sequence Number in a target cell, and determine an MB S configuration for use by a UE requesting a handover accordingly.

    Abstract: The exchange of resource allocation assistance information between a requester User Equipment (UE) and an assistant UE allows the requester to make better resource allocation decisions. The assistance information may include a blacklist, a whitelist, resource allocation information, a candidate resource set, and measurement information, for example. Both UEs may have an assistance configuration to assist in the exchange of resource allocation assistance information, that may be obtained from a third apparatus, such as a base station. The configuration may include information related to when to trigger assistance, identities of UEs, and types of assistance information, for example. The requester may, based on the assistance information received, modify a candidate resource set at a Medium Access Control (MAC) layer. The requester may, at the MAC layer, determine a configured sidelink grant for a selected destination using assistance information targeting this destination.

    Abstract: Radio network Positioning Reference Signals (PRSs) may be managed dynamically via user equipment (UE) requests triggered by measurements in accordance with initial PRS configurations, whereby a UE contacts an Access and Mobility Management Function (AMF) and/or a Location Management Function (LMF). Similarly, an LMF may initiate adjustments in PRS configurations and transmission via communications with base stations, UEs, and/or AMFs. Dynamic signaling of PRS configurations may be achieved via legacy protocols and/or New Radio Positioning Protocol A (NRPPa), for example. A requests from a UE for PRS configuration adjustment may include an indication of a required level of service or of a class of service, for example, and/or an indication of signal measurements, a position estimate, an indication of a capability of the UE.
