Abstract: The method includes a processor of a first UE receiving first group information for a user group with user-device members, the first group information including information for mapping a sidelink channel resource for each of the user-device members to perform a groupcast communication over sidelink for the user group, the first UE being a user-device member of the user group. The method further includes receiving second group information for transmitting data within the groupcast communication, the second group information including updated information of the first group information that is specific to the first UE, initiating a first transmission process to transmit a first data block to the user group for the groupcast communication over the sidelink based on the first group information, and adapting the first transmission process of the first data block based on the second group information.

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: 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.
