1. A method in a source User Equipment (UE), for group transmissions in a wireless communications system, wherein the wireless communications system comprises a group of UEs, including the source UE, which is assigned a first group Identity (ID), and wherein the source UE has data to be cooperatively transmitted by the group of UEs in a group transmission to a Radio Access Network (RAN) node, the method comprising:
transmitting, to the group of UEs, a SideLink (SL) message, wherein the SL message comprises the data to be transmitted to the RAN node, a source UE ID identifying the source UE, the first group ID identifying the group of UEs receiving the data and an indicator indicating that the data comprised in the SL message is to be transmitted cooperatively by the group of UEs in a group transmission to the RAN node;
creating a group message, based on the SL message, wherein the group message is created by scrambling the data comprised in the SL message with a second group ID identifying the group of UEs and adding the source UE ID to the group message; and
transmitting, cooperatively with the UEs assigned to the group, the group message to the RAN node.
