摘要 |
P/S conversion section 302 performs parallel/serial conversion of data sequences #1 through #4 input in parallel, in accordance with control by assignment control section 303, so that data to a higher-priority communication terminal is assigned to an upper bit in one symbol; M-ary modulation section 304 performs M-ary modulation on the data that has been subject to parallel/serial conversion; S/P conversion section 305 converts a symbol that has been subject to M-ary modulation to parallel form; multipliers 306-1 through 306-4 execute spreading processing on the symbols output in parallel; multiplexing section 309 multiplexes the symbol that has been subject to spreading processing with an assignment notification signal that has been subject to spreading processing; and radio transmitting section 310 transmits the multiplex signal.
