Receiving device and radio communication method
The present invention is designed to reduce the delay time to transmit delivery acknowledgment information as feedback in response to data channels. According to one aspect of the present invention, a receiving device has a receiving section that receives one or more code blocks mapped per given number of symbols, in a slot in which a data signal is scheduled, and a control section that controls the transmission of delivery acknowledgment information in response to the data signal in the slot, based on the decoding results of the code blocks mapped per given number of symbols.
1. A receiving device comprising:
a receiver that receives one or more code blocks mapped per given number of symbols, in a slot in which a data signal is scheduled; and
a processor that controls transmission of delivery acknowledgment information in response to the data signal in the slot, based on decoding results of the code blocks mapped per given number of symbols,
wherein the processor controls a size of the code blocks based on a maximum code block size in accordance with a coding scheme and at least one of a number of resource blocks allocated to the data signal, a modulation scheme, a coding rate, and a number of layers,
wherein the processor controls a coding length and/or the coding rate of the code blocks based on at least one of the number of resource blocks allocated to the data signal, the modulation scheme, the coding rate, and the number of layers,
wherein the processor determines whether or not to transmit the delivery acknowledgment information in the slot based on at least one of the number of resource blocks allocated to the data signal, the modulation scheme, the coding rate, and the number of layers, and
wherein the processor controls a coding length and a coding rate of the code block regardless of at least one of the number of resource blocks allocated to the data signal, the modulation scheme, the coding rate, and the number of layers.
2. A radio communication method comprising, in a receiving device:
receiving one or more code blocks mapped per given number of symbols, in a slot in which a data signal is scheduled; and
controlling transmission of delivery acknowledgment information in response to the data signal in the slot, based on decoding results of the code blocks mapped per given number of symbols,
wherein the receiving device controls a size of the code blocks based on a maximum code block size in accordance with a coding scheme and at least one of a number of resource blocks allocated to the data signal, a modulation scheme, a coding rate, and a number of layers,
wherein the receiving device controls a coding length and/or the coding rate of the code blocks based on at least one of the number of resource blocks allocated to the data signal, the modulation scheme, the coding rate and the number of layers,
wherein the receiving device determines whether or not to transmit the delivery acknowledgment information in the slot based on at least one of the number of resource blocks allocated to the data signal, the modulation scheme, the coding rate, and the number of layers, and
wherein the receiving device controls a coding length and a coding rate of the code block regardless of at least one of the number of resource blocks allocated to the data signal, the modulation scheme, the coding rate, and the number of layers.
