Disclosed is a method of a sidelink related operation of a remote User Equipment (UE) in a wireless communication system, the method including performing measurement on one or more UEs by the remote UE, selecting a relay UE by the remote UE based on a result of the measurement, and receiving a notification message from the relay UE, wherein the notification message may include information informing that the relay UE has failed in Uu RRC connection establishment.

Apparatus and methods for extending and enhancing wireless networks. An exemplary wireless network configured according to the disclosure uses in-service Wireless Network Clients (WNCs), such as mobile phones, laptops, etc., to extend and enhance the wireless network coverage via peer-to-peer sub-networks. In one implementation, each WNC is configured to operate as a Service Access Node (SAN) to other wireless client devices in the same network. The SAN provides peer-to-peer communications capabilities (to communicate with wireless clients) and gateway functionality (to aggregate data traffic over its own uplink communications), thereby enabling wireless clients to “piggyback” their data link onto the WNC. Peer Control Manager (PCM) software on each WNC enables, disables, and controls the service functions for that WNC in accordance with an overarching Peer Controller (PC) entity operated by an Access Point Controller/Core Network.

An automatic train communications system includes a plurality of electronic train devices and a multi-channel communications network, wherein each electronic train device comprises a radio module configured to support a plurality of communications protocols and a plurality of frequency bands, and select a communications protocol and/or a frequency band from the plurality of communications protocols and frequency bands based on at least one performance criterium to reliably communicate with one or more electronic train devices via the multi-channel communications network.

A communication method of a first sidelink terminal in a wireless communication system is provided. The communication method includes obtaining sidelink radio bearer configuration information, identifying default sidelink radio bearer information in the sidelink radio bearer configuration information, and transmitting data to a base station or a second sidelink terminal based on the default sidelink radio bearer information.

A first user equipment (UE) device manages the cast type for transmissions to other UE devices within a group during handovers. At least two cast types can be used from a set of cast types that comprises groupcast and unicast although other cast types may be included.

A communication apparatus includes a transition information generation unit that generates a plurality of pieces of different transition information related to transition from a first mode in which centralized communication is performed by an access point to a second mode in which no centralized communication by an access point is performed and a frame generation unit that generates a frame containing the transition information.

Systems, apparatuses, methods, and computer-readable media, are provided for managing background data transfer sessions based on network events monitored by one or more network elements. Embodiments may be relevant to multi-access edge computing (MEC) and Automotive Edge Computing Consortium (AECC) technologies. Other embodiments may be described and/or claimed.

Provided are a path switching method and apparatus, a path switching configuration method and apparatus, a communication node and a non-transitory computer-readable storage medium. The path switching method is applied to a first user equipment (UE) and may include receiving path switching configuration information, and switching a communication link with a target node from a first link to a second link according to the path switching configuration information.

A first wireless device and a second wireless device are connected via a first IF and a second IF. A first controller performs control so as to execute a first mode in which a first communication interface performs communication with a base station device and a second controller does not perform communication between a second communication interface and a terminal device. When the reception strength of a signal from the base station device received in the first communication interface is smaller than a threshold value, the first controller performs control so as to execute a second mode in which the first communication interface performs communication with the base station device and the second controller performs communication between the second communication interface and the terminal device.

According to one embodiment, a wireless apparatus determines a state of a first wireless link with a first mobile station and a state of a second wireless link with a second mobile station in a first communication mode, and transmits a first signal to the first and the second mobile stations in accordance with the states of the first and the second wireless links. In response to the first signal, the first communication mode is changed to a second communication mode in which the wireless apparatus communicates with the second mobile station via a direct communication between the first and the second mobile stations.
