US 10,219,257 B2 · Method and device for transmitting uplink control information

Abstract

The present invention relates to a method and a device for transmitting uplink control information in a wireless communication system supporting carrier merging of a plurality of cells comprising a first cell and a second cell, the method comprising the steps of: receiving a first uplink grant from a base station by means of a random access response; the first uplink grant scheduling first physical uplink shared channel (PUSCH) transmission on a first cell and receiving a second uplink grant from the base station by means of a physical downlink control channel (PDCCH); and the second uplink grant scheduling a second PUSCH transmission on a second cell and, if the first PUSCH transmission and the second PUSCH transmission are configured in the same subframe, transmitting uplink control information to the base station on the second cell by means of a second PUSCH, wherein the first PUSCH transmission scheduled on the first cell is dropped.

Dependent claims

A method for transmitting uplink control information by a user equipment in a wireless communication system supporting carrier aggregation of a plurality of cells containing a first cell and a second cell, the method comprising:

receiving a random access response via a physical downlink shared channel (PDSCH) from a base station,
wherein the random access response schedules a first physical uplink shared channel (PUSCH) transmission on the first cell;
receiving downlink control information via a physical downlink control channel (PDCCH) from the base station,
wherein the downlink control information schedules a second PUSCH transmission on the second cell;
and
when the first PUSCH transmission and the second PUSCH transmission are configured in a same subframe, transmitting the uplink control information to the base station on the second cell via the second PUSCH,
wherein the first PUSCH transmission scheduled on the first cell is dropped.

A user equipment configured to transmit uplink control information to a base station in a wireless communication system supporting carrier aggregation of a plurality of cells containing a first cell and a second cell, the user equipment comprising:

a transceiver configured to transmit and receive a signal;
and
a processor operably connected to the transceiver and configured to:
control the transceiver to receive a random access response via a physical downlink shared channel (PDSCH) from a base station,
wherein the random access response schedules a first physical uplink shared channel (PUSCH) transmission on the first cell,
control the transceiver to receive downlink control information via a physical downlink control channel (PDCCH) from the base station,
wherein the downlink control information schedules a second PUSCH transmission on the second cell,
when the first PUSCH transmission and the second PUSCH transmission are configured in a same subframe, control the transceiver to transmit the uplink control information to the base station on the second cell via the second PUSCH,
wherein the first PUSCH transmission scheduled on the first cell is dropped.
