SEARCH SPACE FOR ePDCCH CONTROL INFORMATION IN OFDM-BASED MOBILE COMMUNICATION SYSTEM Russian patent published in 2016 - IPC H04L5/00 

FIELD: radio engineering, communication.

SUBSTANCE: receiving method comprises receiving a signal including downlink control information mapped to a first search space which is configured according to a first pattern or a second search space which is configured according to a second pattern, each pattern defining one or a plurality of physical downlink control channel (PDCCH) candidates for each of a plurality of aggregation levels, each PDCCH candidate being consisting of a control channel element (CCE) or a plurality of aggregated CCE, wherein a first plurality of aggregation levels defined by the first pattern overlap with a second plurality of aggregation levels defined by the second pattern, and the second pattern defines one or a plurality of second PDCCH candidates with at least one of the first plurality of aggregation levels defined by the first pattern and another second PDCCH candidate with an aggregation level higher than any one of the first plurality of aggregation levels; and monitoring one or a plurality of first PDCC candidates included in the first search space or one or a plurality of second PDCCH candidates included in the second search space and acquiring downlink control information for a receiving apparatus.

EFFECT: minimising signalling overhead.
