摘要： First resource blocks of a radio resource each include a first number of subcarriers and a second number of subframes having the first size. In this case, second resource blocks are formed, each second resource block including fewer subcarriers than the first number and fewer subframes than the second number based on the first resource blocks. A signal is transmitted in the first resource block or second resource block, and particularly, signals of first and second channels are transmitted by sharing the first resource block.
