Patent ID: 8565264

Claim:
A radio communication system comprising: a radio transmission apparatus that includes: a first data processing section that is placed at a MAC sub-layer which mediates data transmission between a transport channel and two or more logical channels, and sends out data to the transport channel in such a way that data received from two or more logical channels are integrated, control information to be transferred to an associated entity which is placed at a MAC sub-layer of a receiving side is added, and transmission order information representative of transmission order is added; and a data transmission section that is placed at a physical layer, receives data transmitted from the first data processing section via the transport channel and transmits the received data by radio; and a radio receiving apparatus that includes: a data receiving section that is placed at a physical layer, receives data transmitted by radio and transmits the data to a transport channel; and a second data processing section that is placed at MAC sub-layer which mediates data transmission between the transport channel and two or more logical channels, and operates in accordance with the control information which is added to the data received from the transport channel, so that the control information is removed from the data to separate the data into data associated with individual logical channel and distribute the data to the individual logical channel, wherein the second data processing section determines, based on the transmission order information added to the received data, whether the received data is data received in delay out of the transmission order, and as to the control information added to the data received in delay, determines whether the inconvenience is caused when the control information is executed in timing of being received in delay and disregards the control information causing the inconvenience not to be executed.
