    摘要： Apparatus, and an associated method, for providing transmit diversity to an open-loop MIMO communication scheme, such as a point to multipoint broadcast service in a cellular system. Multiple data streams of the broadcast data are broadcast by way of transmit diversity antennas of a sending station. The data symbols of the separate data streams are phase-shifted to be offset in phase from one another. The data streams, once the data symbols thereof are selectably phase-shifted by a phase shifter, are applied by an applier to sending nodes of the respective cells.

    摘要： A system is disclosed for providing multimedia broadcast multicast services (MBMS) using a single cell point-to-multipoint (SC-PTM) communication. The system includes a processor 720 configured to promote transmitting scheduling information for a multicast traffic channel (MTCH) 320 related to an MBMS service onto a physical downlink control channel (PDCCH) 334. In a first transmission, the scheduling information includes modulation and coding information related to the MBMS service. In a second transmission, the scheduling information includes an indicator 350 instead of the modulation and coding information. The indicator 350 related to the MBMS service and indicating to a user equipment 10 to use the modulation and coding information in the first transmission for the MBMS service.
