1. A method comprising:
receiving, by a first wireless device from a base station, configuration information associated with direct data transmission between the first wireless device and one or more wireless devices, wherein the configuration information comprises information of a resource selection mode for direct data transmission, and wherein the information of a resource selection mode indicates a resource pool from which the first wireless device selects a resource for direct data transmission to one or more wireless devices;
transmitting, to the base station, a radio resource control (RRC) message comprising information of a first target identity identified based on a discovery procedure and information of a second target identity identified based on the discovery procedure, wherein the first target identity is associated with at least one target wireless device of a first group of target wireless devices, and wherein the second target identity is associated with at least one target wireless device of a second group of target wireless devices; and
transmitting, to the base station, a signal associated with a MAC-layer message, wherein the MAC-layer message comprises:
a first field that indicates the first target identity and indicates a first group identity associated with the first target identity; and
a second field that indicates the second target identity and indicates a second group identity associated with the second target identity.
