Abstract: One of the embodiments of the present invention relates to a method for controlling a D2D discovery process at a discovering user equipment. The method comprises determining by the discovering user equipment whether discovery information in a discovering message received from a discovered user equipment is sufficient for performing the D2D discovery process or not. In response to a positive result of the determination, the user equipment continues the discovery procedure without involvement of network node, at least by using the discovery information in the discovering message; in response to a negative result of the determination, the user equipment sends a request to a network node for assistance on further discovery information for performing the D2D discovery process, and then receives the further discovery information from the network node. Embodiments of the present invention also provide methods, apparatuses and computer program products.

Abstract: Various communication systems may benefit from a high quality of service (QoS). For example, fifth generation (5G) wireless communication systems may benefit from differentiated service flows in the user plane that may impact a core network. According to certain embodiments, a method can include determining at a serving radio access network whether a modification of a service flow will impact at least one of a core network service monitoring, controlling, and configuring, and initiating, based on the determination, the modification of the service flow directly with a user equipment or through a controlling network entity located in the core network.

Abstract: Systems, methods, apparatuses, and computer program products for sidelink (SL) based multi-hop UE relaying, for example, to support tracking applications are provided. One method may include determining, at a user equipment (UE), to which tier of a sidelink (SL) based multi-hop user equipment (UE) relaying the user equipment (UE) belongs. The method may also include determining at least a relaying mode and arrangement of transmit and receive occasions for sidelink (SL) transmission and reception in dependence on the determined tier that the user equipment (UE) belongs, and performing, on the determined transmit and receive occasions, transmit and receive operations for the sidelink (SL) based multi-hop user equipment (UE) relaying based on the determined relaying mode and arrangement.

Abstract: Systems, methods, apparatuses, and computer program products for new radio (NR) sidelink relay of small data transmissions (SDT) are provided. One method may include determining whether conditions to use SDT via at least one relay user equipment are met. When it is determined that the conditions to use the SDT are met, the method may include transmitting a SDT relaying request comprising a SDT payload to the at least one relay user equipment. The method may also include receiving a SDT response, from the at least one relay user equipment, based on how the SDT relaying request is transmitted.

Abstract: The present invention provides apparatuses, methods, systems, computer programs, computer program products and computer-readable media for reducing overhead for Quality-of-service (QoS) monitoring of vehicle-to-everything (V2X) services. The method comprises receiving, at a user equipment, from a serving network, a request for a Quality-of-Service (QoS) monitoring session, making a first determination, at the user equipment, whether the user equipment is relevant for the request, based on the content of the request, making a second determination, at the user equipment, if it is determined in the first determination that the user equipment is relevant, whether the request is received in dedicated signaling or common signaling, deciding, at the user equipment, whether or not to initiate the requested QoS monitoring session based on the second determination.

Abstract: An apparatus in a network node has circuitry configured for causing a scheduling of an uplink transmission for a first user equipment and a downlink reception for a second user equipment on at least one resource, wherein the at least one resource is at least partially shared between the first user equipment and second user equipment. The apparatus has circuitry configured for providing an instruction, to the first user equipment, to transmit a first signal within the at least one resource. The apparatus also has circuitry configured for providing an instruction, to the second user equipment, to detect the first signal within the at least one resource. The apparatus having further circuitry configured for receiving information, from the second user equipment, wherein the information includes an indication of whether the second user equipment has detected the first signal.

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.

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.
