PDCCH MONITORING METHOD AND APPARATUS IN A CARRIER JUNCTION SYSTEM

摘要

The present invention relates to a PDCCH monitoring method in a carrier junction system, comprising: monitoring a plurality of candidate PDCCHs in an overlapping region between a PDCCH search space of a first component carrier and a PDCCH search space of a second component carrier; and receiving downlink control information through one PDCCH out of the plurality of candidate PDCCHs, which has succeeded in decoding. The PDCCH having succeeded in decoding is a shared PDCCH that contains shared control information, a PDCCH for a self-scheduling component carrier without a carrier indicator field, or a PDCCH for a primary component carrier.
