Terminal, communication method, and base station for mapping transport blocks
There is provided a communication device that communicates with another communication device, the communication device comprising: an arranging unit configured to arrange a demodulation reference signal and a group including a plurality of code blocks in a radio frame; and a transmitting unit configured to transmit the radio frame to the other communication device, wherein the plurality of code blocks are arranged in the radio frame based on a position of the demodulation reference signal in the radio frame.
1. A terminal comprising:
a control unit configured to map a transport block including a plurality of code blocks to a plurality of symbols; and
a transmission unit configured to transmit a signal including the plurality of symbols,
wherein the control unit maps the transport block to the plurality of symbols so that a number of resource elements of a first code block is less than a number of resource elements of a second code block, the first code block being nearest to a demodulation reference signal in a time domain, and the second code block being farthest from the demodulation reference signal in the time domain.
2. The terminal as claimed in claim 1 , wherein the demodulation reference signal is arranged near to a beginning of the plurality of symbols.
3. A terminal comprising:
a reception unit configured to receive a transport block including a plurality of code blocks mapped to a plurality of symbols; and
a control unit configured to determine that, in the plurality of symbols, a number of resource elements of a first code block is less than a number of resource elements of a second code block, the first code block being nearest to a demodulation reference signal in a time domain, and the second code block being farthest from the demodulation reference signal in the time domain.
4. A communication method of a terminal, comprising:
a control procedure of mapping a transport block including a plurality of code blocks to a plurality of symbols; and
a transmission procedure of transmitting a signal including the plurality of symbols,
wherein the control procedure includes a procedure of mapping the transport block to the plurality of symbols so that a number of resource elements of a first code block is less than a number of resource elements of a second code block, the first code block being nearest to a demodulation reference signal in a time domain, and the second code block being farthest from the demodulation reference signal in the time domain.
5. A base station, comprising:
a transmission unit configured to transmit a transport block including a plurality of code blocks mapped to a plurality of symbols; and
a control unit configured to determine that, in the plurality of symbols, a number of resource elements of a first code block is less than a number of resource elements of a second code block, the first code block being nearest to a demodulation reference signal in a time domain, and the second code block being farthest from the demodulation reference signal in the time domain.
