    Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of a proactive switch of vehicle-to-everything communication from a device-to-device connection to a connection routed by one or more network devices. In example embodiments, a first terminal device receives, from a second terminal device via a device-to-device connection, an indication of a decision to switch the device-to-device connection to a connection routed by at least one network device for communication with the second terminal device. Based on the received indication from the second terminal device, the first terminal device then determines proactive switching from the device-to-device connection to the routed connection to be performed. The first terminal device then sends a request to a first network device of the at least one network device to set up the routed connection, the request indicating a cause for the determined proactive switching.

    Abstract: A first user equipment able to communicate with other user equipments via sidelink communications determines a procedure to use for selecting a host of a coordination of sidelink discontinuous reception when receiving a connection request from a second user equipment, and based on whether a requirement for a flow corresponding to the connection request meets a threshold. The first user equipment then performs sidelink discontinuous reception coordination between the first and second user equipment based on the determined host. The first user equipment sends configuration a second user equipment to use for discontinuous reception for the sidelink communications, or it requests help from a second user equipment to perform alignment of discontinuous reception for the sidelink communications.

    Abstract: Systems, methods, apparatuses, and computer program products for remote user equipment direct to indirect path switching in sidelink relay are provided. For example, a method can include receiving, at a user equipment from a network element, a system information block message having an information element to configure monitoring of paging messages at a common paging occasion, which can be configured for user equipment that are in idle or inactive state and that are configured to act as a user-equipment-to-network relay user equipment. The method may also include monitoring a page at the common paging occasion based on the information element. The method may further include sending a random access preamble dedicated to the user equipment in response to the page. The method may additionally include performing a state transition to connected mode only after a response to the random access preamble is received.
