PROBLEM TO BE SOLVED: To provide a method for performing local transmission and wide area transmission in a wireless broadcast communication network. SOLUTION: In order to perform broadcast communications of transmission of different type having a hierarchy with different communication-possible range in a wireless broadcast communication network, each base station processes data for the wide area transmission according to a first mode (or coding scheme and modulation scheme) (S812), and processes data for the local transmission according to a second mode (S814). Based on each desired communication-possible range for the wide area transmission and the local transmission, each of the first mode and the second mode is selected. Each base station performs the broadcast communication on the local transmission and the wide area transmission as well as pilots related to them, based on different characteristics for a multi-frequency network and a single network.
