    Abstract: Systems, methods, apparatuses, and computer program products for sidelink group coordination for group-specific synchronization reference are provided. For example, a method can include determining, by a user equipment, whether a first condition is met for coordination on group synchronization reference for a group of user equipment. The method can also include determining, by the user equipment, whether a second condition is met to act as group synchronization reference user equipment for the group. The method can further include transmitting, by the user equipment, a group synchronization reference signal when determined to act as the group synchronization reference user equipment. The method can additionally include performing, by the user equipment, a reduced synchronization search when determined not to act as the group synchronization reference user equipment.

    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: There is provided a method for a network node, comprising: determining that a remote user equipment (UE) in a cell requires a path switch, the path switch comprising switching the remote UE to connect with the network node via a relay UE; providing, for the remote UE, a connection configuration for connecting with the network node via the relay UE; after providing the connection configuration, determining that the relay UE is to be handed over to another cell; transmitting a message to the relay UE, the message prohibiting the relay UE from establishing a sidelink connection with the remote UE.

    Abstract: When there is a role switch between a first apparatus acting as a relay node towards a wireless network for one or more second apparatuses acting as remote nodes a relay context used by the first apparatus towards the wireless network is communicated to a second apparatus using sidelink communication. After that the first apparatus starts to act as a remote node and the second apparatus starts to act as a relay node using the relay context. Use of the same relay context makes the role switch transparent to the wireless network.

    Abstract: Systems, methods, apparatuses, and computer program products relating to the coexistence of a first mode and second mode of vehicle-to-vehicle (V2V) communications. One method includes allocating, to a user equipment (UE) operating in a first mode of V2V communication that is also configured to use resources from a shared transmit (Tx) pool of a second mode of V2V communication, a pair of resources. The first of the pair of resources may be allocated from an exclusive Tx pool for the first mode, and the second of the pair of resources may be allocated from the shared Tx pool of the second mode of V2V communication.

    Abstract: There is provided a method at a first user equipment, the method comprising: deciding to set up a unicast sidelink, SL, connection with a second user equipment; determining whether or not a radio access network serving the first user equipment or a radio access network serving the second user equipment is able to assist in setting up the unicast SL connection; performing one of the following: upon determining the positive, applying a L1 unicast-based SL connection for setting up the unicast SL connection, upon determining the negative, applying a L1 broadcast-based SL connection for setting up the unicast SL connection; and communicating with the second user equipment over the unicast SL.

    Abstract: The use of PUCCH resources can be more efficient such as by sharing PUCCH resources between URLLC UEs and non-URLLC UEs in a controllable way enhanced with a smart deterministic downlink polling when needed. A method comprises receiving, by a user equipment from a network node of a communication network, information comprising a given physical uplink control channel resource instance allocated to the user equipment, wherein the physical uplink control channel resource instance is allocated to more than one user equipment including the user equipment; signaling the network node using an allocated physical uplink control channel resource instance in a given sub-frame; and, receiving polling form the network node, wherein the polling comprises an uplink grant.
