SEARCH SPACE FOR EPDCCH CONTROL INFORMATION IN AN OFDM-BASED MOBILE COMMUNICATION SYSTEM

摘要

The present invention relates to a method for receiving control information within a subframe of a multi-carrier communication system supporting carrier aggregation, the method comprising the following steps performed at a receiving node: performing a blind detection for the control information within a search space by means of a first search pattern, wherein the first search pattern is one of a plurality of search patterns, each of the plurality of search patterns comprising a plurality of candidates distributed on any of a plurality of aggregation levels, and wherein the plurality of search patterns further comprises a second search pattern whose candidates are non-overlapping the candidates of the first search pattern on the same aggregation levels.

主权项

1. A communication apparatus comprising:
a receiver which, in operation, receives control information mapped to at least one of a first search space and a second search space, the first search space including a first set of PDCCH candidates corresponding to a plurality of aggregation levels, the second search space including a second set of PDCCH candidates corresponding to the plurality of aggregation levels and an aggregation level higher than any one of the plurality of aggregation levels; and a monitor which, in operation, monitors at least one of the first set of PDCCH candidates and the second set of PDCCH candidates for the control information.
