Abstract
Provided are a method and a device for monitoring the control channel in a multicarrier system. The terminal determines a plurality of terminal-specific search spaces corresponding respectively to a plurality of scheduled component carriers in a control region within a subframe. The terminal monitors a downlink control channel for the scheduled component carriers corresponding respectively to the plurality of terminal-specific search spaces.
Claims18
A method for monitoring a control channel in a multiple carrier system, the method comprising:
- receiving information related to a carrier indicator field (CIF);
- if an aggregation of carriers is configured, determining a plurality of UE-specific search spaces of a first carrier;
- monitoring a plurality of downlink control channels within the plurality of UE-specific search spaces of the first carrier;
- and
- receiving downlink control information (DCI) on downlink control channels, which are successfully decoded, via the first carrier,
- wherein a start point for each of the plurality of UE-specific search spaces is determined based on the CIF if the CIF is configured,
- wherein the start point of each of the UE-specific search spaces is different from a start point of a common search space, and
- wherein the DCI received on the downlink control channel of the first carrier includes scheduling information on either a downlink channel or an uplink channel in a second carrier.
A user equipment (UE) for monitoring a control channel in a multiple carrier system, the UE comprising:
- a radio frequency unit configured to transmit and receive radio signals;
- and
- a processor operatively connected to the radio frequency unit and configured to:
- receive information related to a carrier indicator field (CIF);
- if an aggregation of carriers is configured, determine a plurality of UE-specific search spaces of a first carrier;
- monitor a plurality of downlink control channels within the plurality of UE-specific search spaces of the first carrier;
- and
- receive downlink control information (DCI) on a downlink control channels, which are successfully decoded, via the first carrier,
- wherein a start point for each of the plurality of UE-specific search spaces is determined based on the CIF if the CIF is configured,
- wherein the start point of each of the UE-specific search spaces is different from a start point of a common search space, and
- wherein the DCI received on the downlink control channel of the first carrier includes scheduling information on either a downlink channel or an uplink channel in a second carrier.
