Method for transmitting uplink control information in a wireless access system and terminal for same |
摘要 |
The present invention relates to a method for transmitting uplink control information in a wireless access system and a terminal for the same. More particularly, the method comprises the following steps: attaching, if the bit size of uplink control information is larger than a preset number, cyclic redundancy check to the uplink control information; calculating the number of wireless resource elements for transmitting the uplink control information to which the CRC is attached; coding the uplink control information to which the CRC is attached, using a tail biting convolutional coding (TBCC) technique, based upon the calculated number of the wireless resource elements; and transmitting a physical uplink shared channel signal containing the coded uplink control information to a base station, wherein the uplink control information is either hybrid automatic repeat and request acknowledgement/negative acknowledgement (HARQ-ACK/NACK) information or rank indication (RI) information. |

1. A method for transmitting Uplink Control Information in a wireless communication system, the method comprising:
adding a CRC (Cyclic Redundancy Check) to the uplink control information when a bit size of the uplink control information is equal to or greater than a predetermined number; calculating a number of radio resource elements for transmitting the uplink control information having the CRC added thereto; coding the uplink control information having the CRC added thereto by using a TBCC (Tail Biting Convolutional Coding) coding method in accordance with the calculated number of radio resource elements; and transmitting a Physical Uplink Shared Channel signal having the coded uplink control information included therein to a base station, wherein the uplink control information corresponds to any one of HARQ-ACK/NACK (Hybrid Automatic Repeat and reQuest Acknowledgement/Negative-ACK) information and RI (Rank Indication) information. |
