1. A user device, UE, for a wireless communication system, wherein the UE comprises:
one or more processors, wherein the one or more processors configure the UE to establish a sidelink communication with one or more further UEs in the wireless communication system, the sidelink communication comprising a first-stage sidelink control message and a second-stage sidelink control message to be transmitted on sidelink resources, wherein the one or more processors further configure the UE to identify the first-stage sidelink control message and the second-stage sidelink control message for the UE; and
to decode the first-stage sidelink control message for the UE to derive control information embedded in the first-stage sidelink control message, wherein the information embedded in the first-stage sidelink control message indicates time and frequency resources for the second-stage sidelink control message and a configuration of the second-stage sidelink control message,
wherein the information embedded in the first-stage sidelink control message includes a periodicity with which the first-stage sidelink control message and/or the second-stage sidelink control message are repeated, and wherein the periodicity is signaled or selected by a variable number of bits, wherein the variable number of bits represent an entry into a list of periodicities selected from a set of predefined periodicities, and wherein at least one of the predefined periodicities is a predefined value for the periodicity which signals a single-shot transmission of the first-stage sidelink control message and/or the second-stage sidelink control message without any periodicity.
