TRANSMISSION DEVICE, RECEPTION DEVICE, TRANSMISSION METHOD, AND RECEPTION METHOD

摘要

A transmission device includes multiplexing means for multiplexing a unicast channel, an MBMS channel, a unique pilot channel unique to a particular cell, and a common pilot channel common to a plurality of cells so as to crate a transmission symbol. The multiplexing means time-division multiplexes a unicast frame containing the unicast channel and an MBMS frame containing the MBMS channel by the same frequency band. The insertion density of the common pilot channel contained in the MBMS frame is higher than the insertion density of the unique pilot channel contained in the unicast channel.
