UPLINK TRANSMISSION METHOD AND UPLINK TRANSMISSION DEVICE

摘要

One embodiment of the present specification discloses an uplink transmission method performed by a terminal in a multi-cell environment for sharing one uplink resource. The uplink transmission method can comprise the steps of: receiving control information for setting such that one uplink is shared by a first cell and a second cell, wherein the control information sets such that an uplink control channel and an uplink shared channel are not transmitted simultaneously on the same uplink frame; selecting one channel if a first scheduling request (SR) for the first cell and uplink control information (UCI) for the second cell are requested to be simultaneously transmitted on the same subframe through the uplink control channel for the first scheduling request and through the uplink shared channel for the uplink control information; and transmitting the selected channel on the uplink subframe.
