    Abstract: A system, method and apparatus for mobile communications including is provided. A user equipment (UE) receives measurement configuration parameters including one or more first measurement configuration parameters for handover decisions associated with one or more first services, the one or more first services associated with a first type of service and one or more second measurement configuration parameters for handover decisions associated with one or more second services. The first services are associated with a first type of service and the second services are associated with a second type of service. The UE transmits one or more measurement reports that include the two types of measurement information. The UE then receives a radio resource control (RRC) reconfiguration message indicating a handover to the target cell and establishes a connection with the target cell based on the received the RRC reconfiguration message.

    Abstract: A system, method and apparatus for wireless communications is provided. A user equipment (UE) receives control information including first configuration parameters and second configuration parameters. The first configuration parameters are associated with a plurality of sets of reference signals associated with one or more transmission reception points (TRP)s and a transmission configuration indication (TCI) state. The second configuration parameters for reference signal measurements and reports for identified sets of reference signals. The UE transmits a measurement report based on the second configuration parameters and one or more identified sets of reference signals of the plurality of sets of reference signals. The UE receives scheduling information indicating a first TCI state associated with one or more identified TRPs of the plurality of TRPs of the network node. The scheduling information is based, at least in part, on a plurality of received measurement reports transmitted by a plurality of UEs.

    Abstract: A system, method and apparatus for mobile communications including sidelink transmissions is provided. A user equipment (UE) determines based on a partial sensing resource allocation process associated with a first window size, first radio resources for one or more first sidelink transport blocks. The UE transmits the one or more first sidelink transport blocks based on the first radio resources. The UE receives hybrid automatic repeat request (HARQ) feedback based on a first number of number of negative acknowledgements (NACKs) and a second number of positive acknowledgements (ACKs). Based on application of a threshold, the UE determines second radio resources for one or more second sidelink transport blocks. The UE transmits the one or more second sidelink transport blocks based on the second radio resources.
