Abstract
A method for multiplexing a data information stream, including a systematic symbol and a non-systematic symbol, and a control information stream of at least three types in a wireless mobile communication system is disclosed. The method includes mapping the data information stream to a resource area so that the systematic symbol is not mapped to a specific resource area to which the control information stream is mapped, and mapping the control information stream to the specific resource area.
Claims16
A method of transmitting an uplink signal, the method comprising:
- mapping information symbols on resource elements in a subframe,
- wherein the subframe includes two slots and each slot includes a plurality of Single Carrier Frequency Division Multiple Access (SC-FDMA) symbols;
- mapping reference signal symbols on the resource elements such that the reference signal symbols are present on only one SC-FDMA symbol in each slot;
- and
- transmitting the information symbols and the reference signal symbols via the plurality of SC-FDMA symbols at the subframe,
- wherein rank information symbols of the information symbols are present on four SC-FDMA symbols and each of the four SC-FDMA symbols is separated from the SC-FDMA symbols for the reference signal symbols by one SC-FDMA symbol, and
- wherein Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) information symbols of the information symbols are present on four SC-FDMA symbols and each of the four SC-FDMA symbols is contiguous with the SC-FDMA symbols for the reference signal symbols.
A mobile communication device configured to transmit an uplink signal, the mobile communication device comprising:
- first module for mapping information symbols on resource elements in a subframe including two slots such that each slot includes a plurality of Single Carrier Frequency Division Multiple Access (SC-FDMA) symbols and for mapping reference signal symbols on the resource elements such that the reference signal symbols are present on only one SC-FDMA symbol in each slot of the subframe;
- and
- a second module for transmitting the information symbols and the reference signal symbols via the plurality of SC-FDMA symbols at the subframe,
- wherein rank information symbols of the information symbols are present on four SC-FDMA symbols and each of the four SC-FDMA symbols is separated from the SC-FDMA symbols for the reference signal symbols by one SC-FDMA symbol, and
- wherein Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) information symbols of the information symbols are present on four SC-FDMA symbols and each of the four SC-FDMA symbols is contiguous with the SC-FDMA symbols for the reference signal symbols.
