METHODS AND SYSTEMS FOR PDCCH BLIND DECODING IN MOBILE COMMUNICATION Russian patent published in 2013 - IPC H04L1/00 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to blind decoding of a physical downlink control channel (PDCCH) for user equipment. Several forms of arranging possible CCE combinations are examined and investigated. Based on PDCCH size estimation/information, CCE concatenations that are most likely (of limited sets) can be arrived at. Tree-based concatenations are also devised using largest CCE ordering to align smaller CCE sizes to similar boundaries. By such ordering, the search space for all possible CCE ordering and sizes can be reduced to an efficient tree. Set mapping between possible CCE/RE are also described using a first set to secondary and tertiary sets. Various other ordering and sorting schemes are also detailed that enable blind decoding of a PDCCH channel to be efficiently performed.

EFFECT: cutting processing costs for PDCCH signal blind decoding.
