Abstract: A physical sidelink feedback channel custom indication may be defined to indicate a half-duplex collision between one or more sidelink UE to a transmitting UE involved in the collision. In response to the indication, the transmitting UE may not retransmit the packet involved in the collision, and may stay awake for an extended period of time. A receiving UE that identified the collision and transmitted the indication may retransmit the packets involved in the collision to the transmitting UEs that have not yet received the respective packets.

Abstract: For a UE in a wireless network and able to communicate via sidelink communications with other UE(s), the UE determines whether a specific condition exists indicating the UE has limited availability of CG resources used to communicate for the sidelink communications. The UE sends, using the sidelink communications, a message indicating the limited availability of the CG resources toward the other UE(s). Another UE receives the message indicating a limited availability of CG resources for the UE, and prepares an application in the other UE for a less sensitive mode of operation having less QoS than a mode having a normal QoS. A base station can configure the UE with the CG resources and provide a set of parameters to the UE to be used to form the message for the user equipment to transmit to the other UE(s) using sidelink communications.

Abstract: There are provided measures for enabling/realizing flexible and adaptive QoS monitoring for unicast/groupcast over sidelink communication, which may preferably be capable of enhancing support of unicast/groupcast services over sidelink communication. Such measures exemplarily comprise obtaining a request for QoS monitoring for unicast/groupcast over sidelink communication with a specified quality-of-service profile, which indicates at least one target QoS metric to be monitored, determining a QoS monitoring procedure, wherein a scheme for enforcing QoS monitoring over sidelink communication in collaboration with at least one unicast/groupcast receiving-side device is decided, and performing the QoS monitoring procedure, wherein QoS monitoring messages are exchanged with the at least one unicast/groupcast receiving-side device over the sidelink communication with the specified QoS profile in accordance with the decided scheme and the at least one target quality-of-service metric is derived based thereon.

Abstract: It is provided a method comprising: monitoring if a remote terminal receives a first system information block from a first cell via a first path and a second system information block from a second cell via a second path different from the first path; comparing a content of the first system information block with a content of the second system information block if the remote terminal receives the first system information block and the second system information block; selecting one of the first path and the second path based on a result of the comparing; causing the remote terminal to connect via the selected one of the first path and the second path.

Abstract: Inter-alia, a method is disclosed comprising: determining a suitability to serve as a relay device for a relayed communication between a first device and a second device via one or more relay devices to be selected among one or more relay device candidates; transmitting a message as part of a relay discovery procedure, and with the apparatus acting as one of the one or more relay device candidates; and performing at least one of a transmit power adjustment and/or a radio resource selection for transmitting the message based, at least in part, on the determined suitability.

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: This document discloses a solution for performing rerouting of a relayed connection. In an aspect, a method for an anchor terminal device supporting relaying between an access node and an end terminal device comprises: receiving a message requesting rerouting of said relaying, the message comprising at least one information element indicating at least one candidate terminal device; determining a communication delay between the anchor terminal device and the end terminal device via at least one of said at least one candidate terminal device and comparing the determined communication delay with a maximum delay threshold; if at least one determined communication delay is smaller than the maximum delay threshold, rerouting the relaying between the anchor terminal device and the end terminal device via one of the at least one candidate terminal device that provides the communication delay smaller than the maximum delay threshold, wherein the rerouting is carried out autonomously without receiving from the access node a reconfiguration message instructing the rerouting configuration; and if no communication delay is smaller than the maximum delay threshold, causing transmission of a message to the access node, the message indicating a need for reconfiguration of the relaying.

Abstract: An arrangement for role management in relay communication is disclosed. In relay communication, one user equipment relays communication between a base station and at least one remote user equipment. Initially, the relay user equipment has a better signal to a base station. When the signal changes, a better signal channel may be achieved by switching roles between a relay user equipment and a remote user equipment. This includes detecting that a better signal exists and determining that a change would provide a better signal.
