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: Various communication systems may benefit from improved multiplexing of sidelink logical channels in sidelink groupcast. A method may comprise receiving at least one sidelink groupcast from at least one sidelink transmitter. The method may further include determining a distance to the at least one sidelink transmitter and determining one or more of at least one configured resource or ranging sequence to transmit at least one sidelink feedback based upon the determined distance to the at least one sidelink transmitter. The method may further include transmitting the at least one sidelink feedback to the at least one sidelink transmitter based upon the determined one or more of at least one configured resource or ranging sequence.

Abstract: A method comprising receiving a configuration of a resource associated with sidelink data transmission for a groupcast to a group of terminal devices from an anchoring terminal device, wherein the sidelink data transmission for the groupcast occurs outside an on-duration of a sidelink discontinuous reception cycle, obtaining data related to an event that is to be transmitted for the groupcast, transmitting, outside the on-duration of the sidelink discontinuous reception cycle, a first indication comprising a notification regarding the event using the resource, and transmitting the data for the groupcast.

Abstract: Systems, methods, apparatuses, and computer program products for resource collision avoidance in sidelink for discontinuous reception (DRX). For example, certain embodiments described herein may help to ensure a reliable method for reaching a power saving solution for an autonomous resource selection, using a fixed set of rules, based on concepts of sub-pools. This may be done by indicating a set of resources to user equipment (UEs), which may be used for sensing and selection. The resources provided may be offset by a number of resources selected at random, based on UE-identifier, or as otherwise indicated.

Abstract: A first UE sending via a sidelink messages to second UE(s) indicating the first UE is changing to a different network access node and therefore might be changing a synchronization source, which the second UE(s) use to maintain a sidelink communication between the first and second UEs. The first UE performs a handover process from a first network access node in the first wireless network to the different network access node in the second wireless network. The second wireless network uses the second synchronization source. The first UE attempts to synchronize the second UE(s) to the second synchronization source. The second UE, and first and second networks may interoperate to effectuate this process. Methods, apparatus, software, and computer program products are disclosed.

Abstract: An apparatus, method and computer program product is disclosed. The apparatus may comprise means for wirelessly transmitting a signal representing first payload data from a data source to a plurality of remote receivers. The transmitting means may be configured to send the first payload data to the different remote receivers at one or more of different times, with different power levels or with other artificial signal modifications. For example, the transmitting means may be configured to transmit the first payload data at different times responsive to determining that three or more remote receivers are within receiving range of the apparatus.
