The data amount 100, 300, 400, then the total priority transmission data amount of the time E logical channel 1-3 is 200, 400, 500, respectively. At TTIy (time F), 1000 total transmission data is obtained, and the total priority transmission data amount 200, 400, 500 of logical channels 1-3 is preferentially guaranteed, since logical channels 1, 2 occupy 600 data amounts, logical channel 3 only Can allocate 400 data amount.
