Uplink transmission method and uplink transmission device
First Claim
1. An uplink transmission method, the method comprising:
- determining, by a user equipment (UE) configured with a first cell group of a first base station and a second cell group of a second base station, whether a first physical uplink control channel (PUCCH) transmission including a first scheduling request (SR) toward the first cell group is overlapped in a subframe with a second uplink channel transmission including a second SR toward the second cell group;
determining, by the UE, priorities of the first PUCCH transmission and the second uplink channel transmission when the overlap is determined in the subframe; and
performing, by the UE, both of the first PUCCH transmission including the first SR and the second uplink channel transmission including the second SR based on the determined priorities.

Abstract
One embodiment of the present specification discloses an uplink transmission method in a multi-cell environment in which a single uplink resource is shared. The method may comprise: receiving control information that configures an uplink control channel and an uplink shared channel so that the uplink control channel and the uplink shared channel are not simultaneously transmitted on the same one uplink subframe, wherein the single uplink resource is shared by a first cell and a second cell; selecting any one of the uplink control channel and the uplink shared 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 and the uplink shared channel, respectively; sending the selected channel on the uplink subframe.

7. A user equipment performing uplink transmission, the user equipment comprising:
-
a transceiver which is configured with a first cell group of a first base station and a second cell group of a second base station and transmits and receives signals; and a processor operatively connected to the transceiver and is configured to; determine whether a first physical uplink control channel (PUCCH) transmission including a first scheduling request (SR) toward the first cell group is overlapped in a subframe with a second uplink channel transmission including a second SR toward the second cell group; determine priorities of the first PUCCH transmission and the second uplink channel transmission when the overlap is determined in the subframe; and perform both of the first PUCCH transmission including the first SR and the second uplink channel transmission including the second SR based on the determined priorities. - View Dependent Claims (13, 14)
