    Abstract: A base station belonging to a first cell group (CG) that includes a transceiver configured to connect to a user equipment (UE) and a processor configured to transmit a command to the UE to perform a BWP switch, and monitor a physical uplink control channel (PUCCH) for an acknowledgement or a negative acknowledgement (ACK/NACK) for a predetermined period of time, wherein the predetermined period of time is the sum of a standard-defined period of time between transmission of a radio resource control (RRC) command and receipt of the ACK/NACK, a time to process an RRC command, and a time to perform a BWP switch.

    Abstract: A user equipment (UE) includes a first subscriber identification module (SIM) and a second SIM. The UE is configured to establish a first cellular network connection based on, at least, the first SIM and a second cellular network connection based on, at least, the second SIM. The UE sends, by the first SIM, a first registration request to the network, wherein the first registration request comprises an identification indicating the multi-SIM device is a type of multi-SIM device, receives, by the first SIM, a first registration accept message indicating the first registration request has been accepted, wherein the first registration accept message comprises a first temporary identification for the first SIM and sends, by the second SIM, an access network message comprising one of the first temporary identification or a further temporary identification based on, at least, the first temporary identification.

    Abstract: The exemplary embodiments relate to a user equipment (UE) performing radio link monitoring of a sidelink. The UE may transmit a signal over the sidelink and receive an indication of a type of hybrid automatic repeating request (HARQ) feedback in response to the signal. The UE may then generate a radio link metric associated with the sidelink based on the type of HARQ feedback. The UE may determine that the radio link metric satisfies a predetermined threshold and initiate a keep alive procedure for the sidelink based on the radio link metric satisfying the predetermined threshold.
