Abstract
The present invention relates to a method for receiving control information by a UE in a wireless communication system, and an apparatus for same. More specifically, the method includes a step of receiving reconfiguration downlink control information (DCI), wherein the reconfiguration DCI includes a plurality of reconfigurations relating to a UE group including the UE and is configured so as to be received on the basis of a radio network temporary identifier (RNTI) defined for the reconfiguration DCI.
Claims6
A method for receiving downlink control information (DCI) by a user equipment (UE) served by a plurality of cells in a wireless communication system, the method comprising:
- receiving Radio Resource Control (RRC) configuration information including Radio Network Temporary Identifier (RNTI) information used for resource format indication;
- receiving a Physical Downlink Control Channel (PDCCH) including the DCI related to the resource format indication using the RNTI,
- wherein the DCI included in the PDCCH includes a plurality of resource format indicators related to reconfiguration of uplink-downlink configurations (UL-DL configurations),
- wherein each of the plurality of resource format indicators is related to one of a plurality of uplink-downlink (UL-DL) configurations for the plurality of cells,
- communicating, with one cell of the plurality of cells, based on a UL-DL configuration reconfigured based on one resource format indicator pre- configured for the one cell among the plurality of resource format indicators,
- wherein the RRC configuration information further includes a predetermined offset value, and
- wherein the DCI is monitored during a period determined based on the predetermined offset value.
A user equipment (UE), served by a plurality of cells, for receiving downlink control information (DCI) in a wireless communication system, the UE comprising:
- a transmitter and a receiver;
- and
- a processor coupled to the transmitter and receiver,
- wherein the processor is configured to:
- control the receiver to receive Radio Resource Control (RRC) configuration information including Radio Network Temporary Identifier (RNTI) information used for resource format indication,
- control the receiver to receive a Physical Downlink Control Channel (PDCCH) including the DCI related to the resource format indication using the RNTI,
- wherein the DCI included in the PDCCH includes a plurality of resource format indicators,
- wherein each of the plurality of resource format indicators is related to one of a plurality of uplink-downlink (UL-DL) configurations for the plurality of cells;
- and
- communicate, with one cell of the plurality of cells, based on a UL-DL configuration reconfigured based on one resource format indicator pre-configured for the one cell among the plurality of resource format indicators,
- wherein the RRC configuration information further includes a predetermined offset value, and
- wherein the DCI is monitored during a period determined based on the predetermined offset value.
