User terminal and radio communication method
A terminal is disclosed including a processor that, when an uplink shared channel is used to transmit a delivery acknowledgement signal (HARQ-ACK) and an uplink data (UL-SCH), controls a mapping of the delivery acknowledgement signal based on whether bundling is applied to the delivery acknowledgement signal and based on a number of bits of the delivery acknowledgement signal; and a transmitter that transmits the delivery acknowledgement signal and the uplink data. In other aspects, a radio communication method and a base station are also disclosed.
1. A terminal comprising:
a processor that, when an uplink shared channel is used to transmit a delivery acknowledgement signal (HARQ-ACK) and an uplink data (UL-SCH), controls a mapping of the delivery acknowledgement signal based on whether bundling is applied to the delivery acknowledgement signal and based on a number of bits of the delivery acknowledgement signal; and
a transmitter that transmits the delivery acknowledgement signal and the uplink data,
wherein, when the bundling is applied, if the number of bits of the delivery acknowledgement signal after the bundling is less than or equal to 2 bits, the processor maps the delivery acknowledgement signal to a first resource for puncturing, and if the number of bits of the delivery acknowledgement signal after the bundling exceeds 2 bits, the processor maps the delivery acknowledgement signal to a second resource for rate matching.
2. The terminal according to claim 1 , wherein the processor controls the mapping of the delivery acknowledgement signal based on whether a plurality of code words are scheduled by a single downlink control information.
3. The terminal according to claim 1 , wherein, when the bundling is applied, the processor determines whether to apply puncturing or rate matching on the uplink data based on the number of bits of the delivery acknowledgment signal after the bundling.
4. The terminal according to claim 2 , wherein, when the bundling is applied, the processor determines whether to apply puncturing or rate matching on an uplink transport block based on the number of bits of the delivery acknowledgment signal after the bundling.
5. A radio communication method comprising:
when an uplink shared channel is used to transmit a delivery acknowledgement signal (HARQ-ACK) and an uplink data (UL-SCH), controlling a mapping of the delivery acknowledgement signal based on whether bundling is applied to the delivery acknowledgement signal and based on a number of bits of the delivery acknowledgement signal;
transmitting the delivery acknowledgement signal and the uplink data; and
when the bundling is applied, if the number of bits of the delivery acknowledgement signal after the bundling is less than or equal to 2 bits, mapping the delivery acknowledgement signal to a first resource for puncturing, and if the number of bits of the delivery acknowledgement signal after the bundling exceeds 2 bits, mapping the delivery acknowledgement signal to a second resource for rate matching.
6. A base station comprising:
a processor that, when an uplink shared channel is used to receive a delivery acknowledgement signal (HARQ-ACK) and an uplink data (UL-SCH), determines the delivery acknowledgement signal whose mapping is controlled based on whether bundling is applied to the delivery acknowledgement signal and based on a number of bits of the delivery acknowledgement signal; and
a receiver that receives the delivery acknowledgement signal and the uplink data,
wherein, when the bundling is applied, if the number of bits of the delivery acknowledgement signal after the bundling is less than or equal to 2 bits, the delivery acknowledgement signal is mapped to a first resource for puncturing, and if the number of bits of the delivery acknowledgement signal after the bundling exceeds 2 bits, the delivery acknowledgement signal is mapped to a second resource for rate matching.
7. A system comprising a terminal and a base station:
the terminal comprises:
a processor that, when an uplink shared channel is used to transmit a delivery acknowledgement signal (HARQ-ACK) and an uplink data (UL-SCH), controls a mapping of the delivery acknowledgement signal based on whether bundling is applied to the delivery acknowledgement signal and based on a number of bits of the delivery acknowledgement signal; and
a transmitter that transmits the delivery acknowledgement signal and the uplink data,
wherein, when the bundling is applied, if the number of bits of the delivery acknowledgement signal after the bundling is less than or equal to 2 bits, the processor maps the delivery acknowledgement signal to a first resource for puncturing, and if the number of bits of the delivery acknowledgement signal after the bundling exceeds 2 bits, the processor maps the delivery acknowledgement signal to a second resource for rate matching, and
the base station comprises:
a processor that, when the uplink shared channel is used to receive the HARQ-ACK and the uplink data, determines the delivery acknowledgement signal whose mapping is controlled based on whether bundling is applied to the delivery acknowledgement signal and based on the number of bits of the delivery acknowledgement signal; and
a receiver that receives the delivery acknowledgement signal and the uplink data.
