Method for transmitting uplink control information and device therefor
A method for transmitting uplink control information in a wireless communication system according to an embodiment of the present invention, which is performed by a terminal, may comprise the steps of: determining the number of coded symbols according to the payload size of uplink control information to be transmitted; and mapping the uplink control information to an uplink resource according to the determined number of the coded symbols, wherein the number of the coded symbols is determined using a parameter selected according to the payload size of the uplink control information to be transmitted.
1. A method of transmitting uplink control information on a physical uplink shared channel (PUSCH) in a wireless communication system, the method performed by a terminal and comprising:
receiving a uplink grant for the PUSCH, the uplink grant including a downlink assignment index (DAI);
generating coded symbols of hybrid automatic repeat request acknowledgement (HARQ-ACK) information; and
mapping the coded symbols of the HARQ-ACK information to an uplink resource of the PUSCH, via one of a puncturing scheme or a rate-matching scheme,
wherein which scheme is used between the puncturing scheme and the rate-matching scheme is determined based on a value of the DAI of the uplink grant.
2. The method of claim 1 , wherein a number of the coded symbols of the HARQ-ACK information is determined based on a beta offset, and the beta offset is selected as one of configured beta offset values based on a payload size range to which a payload size of the HARQ-ACK information belongs.
3. The method of claim 2 , wherein the configured beta offset values are received via a higher layer signaling.
4. The method of claim 2 , wherein the beta offset is selected as a first value when the payload size of the HARQ-ACK information belongs to a first payload size range and the beta offset is selected as a second value when the payload size of the HARQ-ACK information belongs to a second payload size range.
5. The method of claim 1 , further comprising:
transmitting the coded symbols of the HARQ-ACK information through the PUSCH.
6. A user equipment (UE) configured to transmit uplink control information on a physical uplink shared channel (PUSCH) in a wireless communication system, the terminal comprising:
a radio frequency (RF) unit comprising a transceiver; and
a processor configured to control the RF unit,
wherein:
the processor is configured to receive a uplink grant for the PUSCH, the uplink grant including a downlink assignment index (DAI), to generate coded symbols of hybrid automatic repeat request acknowledgement (HARQ-ACK) information, and to map the coded symbols of the HARQ-ACK information to an uplink resource of the PUSCH, via one of a puncturing scheme or a rate-matching scheme,
wherein which scheme is used between the puncturing scheme and the rate-matching scheme is determined based on a value of the DAI of the uplink grant.
7. The UE of claim 6 , wherein a number of the coded symbols of the HARQ-ACK information is determined based on a beta offset, and the beta offset is selected as one of configured beta offset values based on a payload size range to which a payload size of the HARQ-ACK information belongs.
8. The UE of claim 7 , wherein the configured beta offset values are received via a higher layer signaling.
9. The UE of claim 7 , wherein the beta offset is selected as a first value when the payload size of the HARQ-ACK information belongs to a first payload size range and the beta offset is selected as a second value when the payload size of the HARQ-ACK information belongs to a second payload size range.
10. The UE of claim 6 , wherein the processor is further configured to transmit the coded symbols of the HARQ-ACK information through the PUSCH.
