Abstract

A wireless communication system is described that consists of at least one RAN, at least one UE. In particular, herein described are means and methods of implementing contention-based (CB) uplink (UL) data transmissions to at least one RAN using common / shared resources, and methods of transmitting downlink (DL) response messages to acknowledge those CB UL data transmissions.
