Abstract
A method for monitoring a downlink control channel, is performed by a user equipment (UE) configured with multiple carriers and includes receiving information on carrier index, determining a plurality of UE-specific search spaces for monitoring the downlink control channel, and monitoring the downlink control channel within the plurality of UE-specific search spaces, wherein location of each of the plurality of the UE-specific search spaces is determined based on the carrier index.
Claims18
A method for monitoring a downlink control channel, the method performed by a user equipment (UE) configured with multiple carriers and comprising:
- receiving radio resource control (RRC) signal including first information on a first carrier in which the downlink control channel is to be monitored and second information on a carrier index;
- determining a plurality of UE-specific search spaces for monitoring the downlink control channel;
- monitoring the downlink control channel within the plurality of UE-specific search spaces of the first carrier indicated by the first information of the RRC signal,
- wherein a location of each of the plurality of UE-specific search spaces is determined based on the carrier index,
- wherein the plurality of UE-specific search spaces are included in the first carrier among the multiple carriers;
- and
- receiving downlink control information (DCI) through the downlink control channel, which is successfully decoded, via the first carrier among the multiple carriers,
- wherein the DCI includes scheduling information on either a downlink channel or an uplink channel in a second carrier among the multiple carriers.
A user equipment (UE) for monitoring a downlink control channel, the UE configured with multiple carriers and comprising:
- a transceiver configured to receive radio resource control (RRC) signal including first information on a first carrier in which the downlink control channel is to be monitored and second information on a carrier index;
- and
- a processor operatively connected to the transceiver,
- wherein the processor is configured to:
- determine a plurality of UE-specific search spaces for monitoring the downlink control channel,
- monitor the downlink control channel within the plurality of UE-specific search spaces of the first carrier indicated by the first information of the RRC signal,
- wherein a location of each of the plurality of UE-specific search spaces is determined based on the carrier index,
- wherein the plurality of UE-specific search spaces are included in the first carrier among the multiple carriers, and
- receive downlink control information (DCI) through the downlink control channel, which is successfully decoded, via the first carrier among the multiple carriers,
- wherein the DCI includes scheduling information on either a downlink channel or an uplink channel in a second carrier among the multiple carriers.
