摘要

A transmitter (10) is provided with an MAC-PDU generating section (12), which multiplexes an information element and generates an MAC-PDU; and a first data unit transmitting section (13), which transmits the generated MAC-PDU, in an MAC layer. The information element is of an MAC-SDU received from an RLC layer, an MAC control block or padding. The MAC-PDU generating section (12) adds to an MAC-PDU an MAC header including a C/T for identifying the type of the information element to be multiplexed into the MAC-PDU and an LI for indicating the size of the information element.
