    Abstract: Systems, apparatus and methods enable layer 2 (L2) relaying optimizations for a remote user equipment (UE) to receive system information (SI) from a relay UE. The relay UE may establish a sidelink communication channel with the remote UE that is in a radio resource control (RRC) idle state, an RRC inactive state, or an out-of-coverage (OOC) state with respect to the base station. The relay UE decodes a relay SI request received through the sidelink communication channel from the first remote UE. The relay SI request indicates requested system information. The Relay UE obtains the requested system information or a subset of the requested system information from a memory device or from the base station and encodes a relay SI response to send to the first remote UE. The relay SI response includes the requested system information or the subset of the requested system information.

    Abstract: The exemplary embodiments relate to a computer-readable storage medium, a device, an integrated circuit and a method that perform operations related to a first user equipment (UE) configured with a side link (SL) connection with a second UE. The operations include generating an SL counter check request including at least a first count for data transmissions from the first UE to the second UE as determined by the first UE. The operations further include transmitting the request to the second UE and receiving a counter check response to the request, the response comprising at least a second count for data transmissions from the first UE to the second UE as determined by the second UE. The operations further include determining a first difference between the first count and the second count and, when the first difference exceeds a threshold, releasing the SL connection with the second UE.

    Abstract: Coordinated leaving for a UE having a first SIM and a second SIM may include decoding, at a baseband processor, an RRC reconfiguration message associated with the first SIM received from a first network. A communication corresponding to the second SIM received from a second network is decoded while the baseband processor is processing the received RRC reconfiguration message. The communication received from the second network is determined to comprise a higher priority than the RRC reconfiguration procedure. Based on determining, a UAI message corresponding to the first SIM is encoded by the baseband processor for transmission to the first network. The UAI message is configured to inform the first network of coordinated leaving and abortion of the RRC reconfiguration procedure. The first SIM is transitioned to an idle mode. An RRC request corresponding to the second SIM is encoded by the baseband processor for transmission to the second network.
