A routing device for installation on a moving platform connects with multiple wireless access devices for wireless interconnection with a wide-area network (WAN). The routing device routes traffic to the WAN through an active one of the wireless access devices. The routing device monitors connection quality between each of the wireless access devices and the WAN and in response to the metric of connection quality for the wireless access device at the active port dropping below a threshold value, reconfigure the routing device to route data traffic to the WAN through a wireless access device at a targeted one of the ports, different from the active one of the ports.

The system comprises one or more of: 1) a hierarchical traffic control network of Traffic Control Centers (TCC's), local traffic controller units (TCUs), 2) A RSU (Road Side Unit) network (with integrated functionalities of vehicle sensors, I2V communication to deliver control instructions), 3) OBU (On-Board Unit with sensor and V2I communication units) network embedded in connected and automated vehicles, and 4) wireless communication and security system with local and global connectivity. This system provides a safer, more reliable and more cost-effective solution by redistributing vehicle driving tasks to the hierarchical traffic control network and RSU network.

One aspect of the present specification provides wireless communication device in a wireless communication system. The wireless communication device includes: at least one transceiver; at least one processor; and at least one computer memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising: receiving, via the at least one transceiver, sidelink signal based on a NR operating band n38 or a NR operating band n47, and wherein predefined reference sensitivity value, which is based on the NR operating band n38 or the NR operating band n47, is applied to the at least one transceiver.

A method for performing wireless communication by a first apparatus is proposed. The method may comprise the steps of: determining power related to a sidelink (SL) transmission, on the basis of a downlink pathloss, wherein the SL transmission includes at least one from among a sidelink-synchronization signal/physical sidelink broadcast channel (S-SS/PSBCH) block transmission, a physical sidelink control channel (PSCCH) transmission, a physical sidelink shared channel (PSSCH) transmission, and a physical sidelink feedback channel (PSFCH) transmission; and performing the SL transmission on the basis of the power related to the SL transmission. For example, on the basis of being configured to monitor a downlink control information (DCI) format 0_0, the downlink pathloss may be determined on the basis of a first reference signal (RS) used for control of power related to a physical uplink shared channel (PUSCH) transmission to be scheduled by the DCI format 0_0. For example, on the basis of not being configured to monitor the DCI format 0_0, the downlink pathloss may be determined on the basis of a second RS related to a synchronization signal block (SSB) for acquiring a master information block (MIB).

Apparatus and methods are provided for sidelink relay-based UE-to-network communication. In one novel aspect, the relay UE performs delayed relay forwarding upon determining the remote UE is in the DRX cycle based on the PC5 configuration. The relay UE buffers the relay traffic and/or sends a suspending indication to the base station to request the base station to suspend the relay traffic to the remote UE. In another novel aspect, the relay UE monitors paging occasions configured for itself and receives paging message from the network intended for the remote UE in one non-connected RRC state. The relay UE sends a PC5 paging message to the remote UE that is in the non-connected RRC state through the established SL based on the received paging message. In one embodiment, the network stores the SL association between the relay UE and the remote UE to the network.
