METHOD FOR TRANSMITTING DATA FROM AN EMITTER TO A PLURALITY OF RECEIVERS

摘要

A safety layer splits into sub-layers for medium access control (MAC), radio link control (RLC), packet data convergence protocol (PDCP) and broadcast/multicast control (BMC). A relaying layer has two parts for radio resource control (RRC) and duplication avoidance (DA). The RRC layer terminates in a universal mobile telecommunications system terrestrial radio access network (UTRAN). An instance of DA is not part of the UTRAN but is moved into a core network. Independent claims are also included for a transmitter-receiver unit and for a communications system both for converting the method of the present invention.
