METHOD AND DEVICE FOR DETERMINING SEARCH SPACE, AND METHOD AND DEVICE FOR DETERMINING CANDIDATE CONTROL CHANNEL RESOURCES Russian patent published in 2014 - IPC H04W16/00 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to communication engineering and can be used to determine search space and candidate control channel resources. The method includes determining the number of downlink control information bits of each type of control channel currently required to be monitored by user equipment (UE); determining a temporary search space corresponding to each type of control channel currently required to be monitored by the UE, according to a mapping relationship between a component carrier for carrying a data channel and a component carrier for carrying a control channel, wherein the mapping relationship is currently used by the UE; and determining that an actual search space corresponding to a selected type of control channel is all or part of control channel elements (CCE) of a union of temporary search spaces corresponding to all or a part of control channels with the same number of downlink control information bits.

EFFECT: high transmission channel throughput.
