Abstract: There are provided measures for handling of paging messages in communication endpoint to network relaying scenarios. Such measures exemplarily comprise, at a relay terminal connected to a mobile access entity of a cellular network systems, selecting, for a terminal to be relayed, a sidelink communication group of a set of configured sidelink communication groups, monitoring network-served paging indicator resources corresponding to said terminal to be relayed for a network-served paging related identifier indicative of transmission of a network-served paging message and information on network-served paging message resources for said transmission of said network-served paging message, transmitting, if said network-served paging related identifier indicative of transmission of said network-served paging message is detected in said network-served paging indicator resources corresponding to said terminal to be relayed and information indicative of paging of said terminal to be relayed is identified in said network-served paging message transmitted in said network-sewed paging message resources as a result of said monitoring, in inter-terminal paging indicator resources configured for said sidelink communication group and next to said network-served paging message resources including said information indicative of paging of said terminal to be relayed, an inter-terminal paging related identifier indicative of transmission of an inter-terminal paging message and information on inter-terminal paging message resources for said transmission of an said inter-terminal paging message, and transmitting said inter-terminal paging message in said inter-terminal paging message resources for said transmission of said inter-terminal paging message.

Abstract: An SL UE that detects a resource conflict associated with a transmitting UE may be able to indicate this resource conflict by transmitting inter-UE coordination information over a PSFCH resource determined based on a group member ID of the transmitting UE. This may be different from transmitting HARQ feedback via a PSFCH resource determined based on a group member ID of the detecting UE.

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: Methods, apparatuses, systems and computer program products for sidelink communication to operate in a power efficient manner. The method comprises determining, at a user equipment, information related to a sidelink traffic load in a first set of resources. The user equipment is configured with an indication of the first set of resources and an indication of a second set of resources. The method also comprises determining the sidelink traffic load in the first set of resources based, at least partially, on the determined information. The method further comprises, based on the determined sidelink traffic load, determining a third set of resources for monitoring. In addition, the method comprises monitoring the third set of resources.

Abstract: Disclosed is a method comprising receiving, by a first terminal device, a first transmission from a second terminal device. The first terminal device measures a channel busy ratio over a first time window. The first terminal device determines a channel occupancy ratio of the second terminal device based at least partly on the received first transmission. The first terminal device updates the channel busy ratio based at least partly on the determined channel occupancy ratio and the measured channel busy ratio. The first terminal device determines one or more sidelink transmission parameters based at least partly on the updated channel busy ratio.
