Method and device for transmitting uplink control information

摘要

One embodiment of the present specification discloses a method for transmitting uplink control information (UCI). The method may be performed by a terminal and comprise receiving control information for setting such that an uplink control channel and an uplink shared channel are not simultaneously transmitted on one uplink subframe; selecting one of the channels, if first uplink control information (UCI) for a first cell and second uplink control information (UCI) for a second cell are requested to be simultaneously transmitted on the one uplink subframe through the uplink control channel in case of the first uplink control information (UCI) and through the uplink shared channel in case of the second uplink control information (UCI); and transmitting at least one from among the first uplink control information (UCI) and the second uplink control information (UCI) on the uplink subframe through the selected channel.

1. A method of transmitting, by a User Equipment (UE), Uplink Control Information (UCI) in a wireless communication system, the method comprising:
receiving, by the UE, control information that configures an uplink control channel and an uplink shared channel to avoid being simultaneously transmitted on a single uplink subframe; determining, by the UE, whether a collision between the uplink control channel and the uplink shared channel is to occur, if first UCI for a first cell and second UCI for a second cell are required to be simultaneously transmitted through the uplink control channel and the uplink shared channel, respectively, on a single uplink subframe; if the UE determines that the collision is to occur, selecting, by the UE, any one of the uplink control channel and the uplink shared channel; and transmitting, by the UE, one or more pieces of the first UCI and the second UCI on the uplink subframe through the selected channel, wherein the UE piggybacks a hybrid automatic repeat request (HARQ) acknowledgement (ACK)/negative ACK (NACK) to another channel other than the selected channel and transmits the HARQ ACK/NACK if each of the one or more pieces of the first UCI and the second UCI comprises the HARQ ACK/NACK.
