    Abstract: Inter-cell mobility may include decoding a first radio resource control (RRC) reconfiguration message received from a first cell. The first RRC reconfiguration message may comprise a first portion of configuration information for performing a cell change to a second cell. A cell change message received from the first cell may be decoded. The cell change message may indicate that a cell change to the second cell is to be performed. A cell change acknowledgment may be encoded for transmission to the second cell. A second RRC reconfiguration message received from the second cell may be decoded. The second RRC reconfiguration message may comprise a second portion of configuration information for performing the cell change to the second cell. The second portion of configuration information may comprise a remaining portion of configuration information to perform the cell change to the second cell.

    Abstract: Disclosed are embodiments for sidelink (SL) capability exchange via a PC5 link between first and second UEs for configuring inter-UE coordination (IUC). In one embodiment, a method entails generating a radio resource control (RRC) message for the second UE, the RRC message including information to identify supported IUC types of the first UE or provide an indication of which resource allocation mode is supported for IUC; signaling with a first SL unicast transmission to the second UE the RRC message; and receiving through a second SL unicast transmission from the second UE the SL capability of the second UE to configure IUC. Also disclosed are techniques for IUC with a UE configured for mode 1 (network-controlled) sidelink (SL) resource allocation.

    Abstract: Various embodiments are described for apparatuses, systems, and methods for pre-forwarding data packets for conditional handover. A UE may connect to a serving base station and perform measurement(s) of one or more neighboring base stations. The UE may provide measurement report(s) corresponding to the measurement(s) to the serving base station. The UE may receive handover assistance information from the serving base station. The handover assistance information may identify at least one neighboring base station that receives downlink packet forwarding of downlink packets intended for the UE prior to handover. The UE may evaluate handover conditions of the neighboring base stations, including the at least one neighboring base station. The UE may perform handover to a first neighboring base station of the at least one neighboring base station based on the at least one neighboring base station receiving downlink packet forwarding of downlink packets intended for the UE prior to handover.
