Title:
RADIO TRANSMISSION DEVICE AND RADIO TRANSMISSION METHOD
Document Type and Number:
WIPO Patent Application WO/2007/083636
Kind Code:
A1
Abstract:
Provided is a radio transmission device capable of improving reception accuracy of a unicast channel received after a multicast channel. In the radio transmission device, a multicast transmission power control unit (106) performs control to reduce the transmission power of the OFDM symbol at the end of a sub frame for a multicast signal outputted from a CP insertion unit (105-2). A radio transmission unit (108) transmits a unicast signal multiplexed by a sub frame multiplexing unit (107) and a multicast signal of controlled transmission power via a transmission antenna (109).
