Abstract
Provided are an apparatus and a method for monitoring a control channel in a multiple-carrier system. The user equipment monitors downlink control channels for a plurality of scheduled component carriers in an extended search space. The user equipment receives downlink control information for the scheduled component carrier via a successfully decoded downlink control channel.
Claims11
A method for monitoring a control channel in multi-cells, the method comprising:
- if a received carrier indicator field (CIF) is configured, monitoring by a user equipment (UE) plural UE-specific search spaces according to aggregation levels;
- monitoring, by the UE, downlink control channel candidates within the plural UE-specific search spaces;
- and
- receiving, by the UE, downlink control information on at least one of the downlink control channel candidates which is successfully decoded.
