Method for transmitting uplink signals in wireless communication system for supporting short transmission time interval, and device for supporting same
The present specification relates to a method for transmitting uplink control channels in a wireless communication system, the method being performed by a terminal and comprising the steps of: receiving, from a base station, information on a cyclic shift (CS) index configuration, which indicates the configuration of an index group for a CS related to uplink control channel transmission; transmitting a first physical uplink control channel by using a first CS index included in the CS index group and a base sequence having a particular length; and transmitting a second physical uplink control channel by using a second CS index included in the CS index group and the base sequence having the particular length, wherein the first CS index is used for symbols that are not overlapped between transmission time intervals (TTI) for transmitting the physical uplink control channel, and the second CS index is used for symbols that are overlapped between the TTI.
1. A method of transmitting an uplink control information in a wireless communication system, comprising:
generating a sequence, using a cyclic shift index among cyclic shift indices for representing Hybrid Automatic Repeat Request ACK (HARQ-ACK) information; and
transmitting the HARQ-ACK information through an uplink control channel using the generated sequence,
wherein the cyclic shift index is based on a number of HARQ-ACK information bits and the HARQ-ACK information, and
wherein the cyclic shift interval is configured to 3 or 6, based on the number of HARQ-ACK information bits.
