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: A user equipment (UE) selects first and second radio resources from respective first and second pools of radio resources. In one example these are primarily allocated for contention-free and scheduling-based channel access, respectively. Content to duplicate in parallel communications is selected based at least on a characteristic of uplink data waiting to be sent (such as size) and/or on the selected first and second radio resources (such as timing difference between them). The UE transmits the selected content on each of the selected first and second radio resources. In the examples the content to duplicate was selected from among the uplink data to send and a scheduling request message. In various embodiments one of these transmissions indicates it's a duplicate, and the duplicated scheduling request message is transmitted on the first resource with the uplink data. These teachings are particularly useful for URLLC data.

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.
