摘要： A transmission apparatus including: a layer multiplexing unit configured to assign, to a radio resource which is divided based on a time, a frequency and a layer, a bit sequence which constitutes at least one information source to be transmitted, in accordance with a communication state and a priority level of the information source; and a layer coding unit configured to perform a layer coding processing for the bit sequence assigned to the radio resource. The layer multiplexing unit performs the assignment so that a length of each bit sequence assigned to each radio resource becomes equivalent.
