Abstract:
1. A base station used in a communication system of an orthogonal frequency division multiplexing (OFDM) scheme, comprising: a unit configured to generate a unicast channel multiplied by a scrambling code specific to a particular cell; a unit configured to generate a multicast broadcast channel multiplied by a scrambling code specific to the particular cell; a unit configured to generate and replicate a pilot channel multiplied by a scrambling code specific to the particular cell; a unit configured to multiplex the pilot channel, the unicast channel and the multicast broadcast channel to generate transmission symbols; and a unit configured to transmit the transmission symbols for each unit transmission frame that includes a plurality of symbols each having a predetermined duration, wherein a unit transmission frame including the unicast channel and a unit transmission frame including the multicast broadcast channel are time multiplexed, and a same frequency component for at least the multicast broadcast channel in the unit transmission frame is multiplied by a same scrambling code, and a symbol in which the pilot channel and a replica of the pilot channel are mapped and another symbol including the multicast broadcast channel are time multiplexed in the unit transmission frame.
